The evolution of autonomy from two cooperative specialists in the fluctuating environments

From microbes to humans, organisms perform numerous tasks for their survival, including food acquisition, migration, and reproduction. A complex biological task can be performed by either an autonomous organism or by cooperation among several specialized organisms. However, it remains unclear how autonomy and cooperation evolutionarily switch. For example, it remains unclear whether and how a group of cooperative specialists can evolve into an autonomous organism. Here, we address this question by experimentally evolving a mutualistic microbial consortium composed of two specialists that cooperatively degrade naphthalene. We observed that autonomous genotypes capable of performing the entire naphthalene degradation pathway evolved from two cooperative specialists and came to dominate the microbial community. This evolutionary transition was driven by the horizontal gene transfer between the two specialists. However, this evolution was exclusively observed to occur in the fluctuating environment supplied with either naphthalene or pyruvate, where mutualism and competition between the two specialists alternated. The naphthalene-supplied environment exerts selective pressure that favors the expansion of autonomous genotypes but was associated with both low cell density and low coexistence levels. In contrast, the pyruvate-supplying environment promoted the coexistence and cell density of the cooperative specialists, thereby increasing the likelihood of horizontal gene transfer. Using a mathematical model, we quantitatively demonstrate that environmental fluctuations facilitate the evolution of autonomy through HGT when the relative growth rate and carrying capacity of the cooperative specialists allow enhanced coexistence and higher cell density in the competitive environment. Together, our results demonstrate that mutualistic cooperation can evolve into autonomous organisms through direct genetic exchange under specific conditions, including the alternation of mutualism and competition in fluctuating environments in a manner frequently occurring in nature.

The "motive cocktail" in altruistic behaviors

Prosocial motives such as social equality and efficiency are key to altruistic behaviors. However, predicting the range of altruistic behaviors in varying contexts and among different individuals proves challenging if we limit ourselves to one or two motives, as most previous studies have done. Here we demonstrate the numerous, interdependent motives in altruistic behaviors and the possibility to disentangle them through behavioral experimental data and computational modeling. In one laboratory experiment (N=157) and one pre-registered online replication (N=1258) across 100 different situations, we found that both third-party punishment and helping behaviors aligned best with a model of seven socioeconomic motives, referred to as a "motive cocktail", including two compound motives. For instance, the "inequality discounting" motives imply that individuals, when confronted with costly interventions, behave as if the inequality between others barely exists. The motive cocktail model also provides a unified explanation for a range of phenomena in the literature.

A kinome-wide synthetic lethal CRISPR/Cas9 screen reveals that mTOR inhibition prevents adaptive resistance to CDK4/CDK6 blockade in HNSCC

The comprehensive genomic analysis of the head and neck cancer (HNSCC) oncogenome revealed frequent loss of p16INK4A (CDKN2A) in most HPV negative HNSCC lesions, often concomitant with amplification of the cyclin D1 (CCND1) gene locus. However, cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors as single agents have shown modest effect in the clinic, even when combined with cetuximab. The aberrant activation of PI3K/mTOR pathway is highly prevalent in HNSCC, and recent clinical trials targeting mTOR showed promising results in terms of objective responses and progression free survival. However, the clinical efficacy of mTOR inhibitors (mTORi) for advanced HNSCC patients may be limited due to intrinsic or acquired resistance. By a kinome-wide CRISPR/Cas9 screen, we identified cell cycle inhibition as a synthetic lethal target for mTORi. Combination of mTORi and palbociclib, a CDK4/6 specific inhibitor, showed strong synergism in HNSCC-derived cells in vitro and in vivo. Remarkably, we found that adaptive increase in cyclin E1 (CCNE1) expression upon palbociclib treatment underlies the rapid acquired resistance to this CDK4/6 inhibitor in HNSCC. Mechanistically, mTORi inhibits the formation of eIF4G-CCNE1 mRNA complexes, with the consequent reduction in mRNA translation and CCNE1 protein expression. Our findings suggest that concomitant mTOR blockade reverts the adaptive resistance to palbociclib, thereby providing a novel multimodal therapeutic option for HNSCC patients by co-targeting mTOR and CDK4/6. Our findings may have broad implications to halt the emergence of palbociclib resistance.

Super-resolution optical imaging reveals accumulation of small mitochondria in the nucleoli of mouse embryos and stem cells

The nuclear mitochondrial DNA (NUMT) is found in cancer cells, but the mitochondrial DNAs entering the nuclei in normal cells have not been captured. Here, we utilized super-resolution optical imaging to capture the phenomenon by the probe PicoGreen and found mitochondrial DNAs and mitochondria accumulated in the nucleoli by four probes and overexpressing the MRPL58-DsRed. Our results provide an new explanation for mtDNA carryover and lay the foundation for the involvement of nuclear export of nucleoli in de novo mitochondrial biogenesis in another of our unpublished articles.

hadge: a comprehensive pipeline for donor deconvolution in single cell

Single cell multiplexing techniques (cell hashing and genetic multiplexing) allow to combine multiple samples, thereby optimizing sample processing and reducing batch effects. Cell hashing conjugates antibody-tags or chemical-oligonucleotides to cell membranes, while genetic multiplexing allows to mix genetically diverse samples and relies on aggregation of RNA reads at known genomic coordinates. We developed hadge (hashing deconvolution combined with genotype information), a Nextflow pipeline that combines 12 methods to perform both hashing- and genotype-based deconvolution. We propose a joint deconvolution strategy combining the best performing methods and we demonstrate how this approach leads to recovery of previously discarded cells in a nuclei hashing of fresh-frozen brain tissue.

Seed size control via phloem end by callose deposition/degradation of β-1,3-glucanase

Seed formation is crucial for lives of plants as well as humans; however, the mechanisms governing seed size require further investigation. Here, we present a new mechanism to modify the seed size by the newly identified phloem end that support nutrient transport, at the chalazal end of the ovule, however, blocked by callose deposition. Callose is removed after central cell fertilization (open state), allowing nutrients to be transported to the seed. However, if fertilization fails, callose deposition persists (closed state), preventing the phloem end from transporting nutrients. {beta}-1,3-glucanase genes, including putative plasmodesmata-associated proteins (AtBG_ppap), were identified as regulators of callose removal. The Atbg_ppap mutant had the phloem end in the closed state and produced smaller seeds due to incomplete callose degradation. In contrast, the AtBG_ppap overexpression line produced larger seeds than the wild type due to continuous callose degradation, indicating that the phloem end regulates substance flow via callose deposition/degradation.

Recombinant Ranpirnase enhances the expression of co-transfected mRNA by modulating cellular metabolic activity

As the worlds first approved prophylactic mRNA vaccine, the development of the Covid-19 mRNA vaccine marks a milestone in mRNA therapeutics. However, achieving efficient transgene expression in therapeutic applications such as protein replacement and cancer therapeutical vaccines remains challenging. This study explores the use of recombinant Ranpirnase, a small ribonuclease, as a novel expression-enhancing tool for mRNA-based therapeutics. In Balb/c mice, co-expression of Ranpirnase significantly increased transgene expression levels by 3-to 6-fold and prolonged expression duration by more than 85%, regardless of mRNA nucleoside modification status. Recombinant Ranpirnase induces a cytostatic state in host cells, stabilizing mRNA and protein transcripts, thereby enhancing transgene expression. Importantly, co-expression of Ranpirnase recombinants did not cause detectable cytotoxicity or alter the tissue distribution of transgene expression, ensuring safety and tolerability at higher translation levels. The compact size of the recombinant Ranpirnase gene allows for seamless fusion with the target gene or co-transfection with existing delivery technologies. Altogether, recombinant Ranpirnase shows promise as an expression-enhancing element in mRNA-based therapeutics, including veterinary applications.

Selectivity-specialized feedback connections mediate the interaction of distinct neural processes during flexible decision-making

Neural activity in the primate brain correlates with both sensory evaluation and action selection aspects of decision-making. However, the intricate interaction between these distinct neural processes and their impact on decision behaviors remains unexplored. Here, we examined the interplay of these decision processes in posterior parietal cortex (PPC) when monkeys performed a flexible decision task. We found that the PPC activity related to monkeys abstract decisions about visual stimuli was nonlinearly modulated by monkeys following saccade choices directed outside each neurons response field. Recurrent neural network modeling indicated that the feedback connections, matching the learned stimuli-response associations during the task, might mediate such feedback modulation. Further analysis on network dynamics revealed that selectivity-specific feedback connectivity intensified the attractor basins of population activity underlying saccade choices, thereby increasing the reliability of flexible decisions. These results highlight an iterative computation between different decision processes, mediated primarily by precise feedback connectivity, contributing to the optimization of flexible decision-making.

Molecular characterization of baculovirus-induced chromatin marginalization and architectural alteration

To facilitate rapid replication and assembly of progeny, baculovirus is known to manipulate the host nuclear microenvironment by inducing chromatin changes in localization and architecture. However, the molecular mechanisms underlying these changes remain unknown. Here, we revealed that the nuclear lamina (NL) protein Lamin A/C interacts with the heterochromatin protein 1 alpha (HP1a) and identified the middle region of HP1a as critical for this interaction. Suppression of Lamin A/C and HP1a expression resulted in a significant inhibition of chromatin marginalization mediated by baculovirus infection. Moreover, the heterochromatin modification H3K9me3, which is recognized and bound by HP1a, also participated in the process of chromatin marginalization. Our live-cell imaging and quantitative analysis unveiled a passive function of marginal chromatin, which involves the formation of a physical barrier that impedes the nuclear egress of the nucleocapsids. Furthermore, baculovirus-induced nuclear F-actin altered the steady-state of intranuclear actin pool, thus regulating the nucleosome disassembly. Overall, our findings illustrate the molecular mechanisms dictating chromatin marginalization and structural alterations during baculovirus infection, shedding new light on the potential function of marginalized chromatin in the origin of its biphasic life cycle. Author SummaryIn our previous study, we illustrated the organization and accessibility of chromatin marginalized by baculovirus infection through a combination of ATAC-seq and biochemical assays. Here, we further dissect the molecular mechanism underlying the baculovirus infection induced chromatin marginalization and disassembly. Specifically, baculovirus utilizes the Lamin A/C-HP1a-H3K9me3 axis to mediate chromatin marginalization at the nuclear periphery. When the interaction between Lamin A/C and HP1a is disrupted, the marginalization of chromatin is also affected. Furthermore, our single-virion tracking results indicate that the marginalized chromatin forms a physical barrier, impeding the nuclear export of nucleocapsids at the very late stage of infection. For the changes in chromatin architecture, we propose a model in which baculovirus infection induced nuclear F-actin compromises the dynamics of nuclear actin pool, which in turn promotes chromatin disassembly. Taken together, we provide a comprehensive understanding of molecular mechanism of baculovirus infection induced changes in chromatin localization and organization, which lay the foundation for studies on how DNA viruses manipulate the nuclear microenvironment.

Maresin-2 Fine-tunes ULK1 O-GlcNAcylation to Improve Post Myocardial Infarction Remodeling

Maresin-2, a specialized pro-solving mediator of inflammation has been consolidated to be a novel cytokine fine-tuning inflammatory cascade. However, the underlying molecular basis is still largely unknown. Focused on cardiac dysfunction and remodeling, we employed in vivo- and in vitro- based genome editing methodology tools including adenosine associated virus, adenosine virus, lenti-virus, plasmid transfection, and CRISPR-Cas9 methodology for investigation. As suggested, exogenous maresin-2 supplement facilitated autophagosome formation by microtubule-associated proteins 1A/1B light chain 3B (LC3) conjugation system under the modulation of O-GlcNAcylation dependent ULK1 activation, whereas reversed by ULK1 S409A and S422A mutagenesis, showcasing the potential O-GlcNAc (O-linked {beta}- N-acetylglucosamine) modifiable sites on ULK1. Moreover, we found that hereafter maresin-2 treatment glutamine-fructose-6-phosphate aminotransferase 1 (GFAT1) which is accessary to sense hexosamine biosynthesis influx is more likely the prime checkpoint for conjugating O-terminal {beta}-N-acetylglucosamine motif onto ULK1, rather than O-linked N-acetylglucosaminyltransferase (OGT). Mechanistically, maresin-2 largely prohibits transforming growth factor-{beta} (TGF-{beta})-activated kinase 1 (TAK1), therefore increasing the availability of TAB1 for GFAT1, which encourages O-GlcNAcylation of ULK1.

Joint analysis of single-cell and bulk tissue sequencing data to reveals the adaptation and remodeling of the tumor microenvironment by breast cancer cells at different stages of brain metastasis process

ObjectiveTo integrate macro-transcriptomics and single-cell sequencing to analyze the differential gene expression between primary and brain metastatic breast cancer cells, as well as between active and dormant cancer cells within brain metastases, exploring their adaptation and remodeling abilities at different stages of brain metastasis. MethodsFour public datasets were used: three mRNA microarray datasets from breast cancer and brain metastasis tissues, and one single-cell RNA sequencing (scRNA-seq) dataset from active and dormant brain metastatic cells. Gene differential expression, pathway enrichment, and cell clustering analyses were performed to compare primary and metastatic breast cancer cells, as well as active and dormant cells in brain metastases, focusing on gene expression, metabolic pathways, and functional pathways. ResultsMetastatic breast cancer cells showed weakened pathways related to the extracellular matrix and protein digestion. Active cells exhibited enhanced cell cycle regulation, tumor proliferation, and hypoxia resistance pathways compared to dormant cells. Clustering analysis revealed that cluster 6, unique to dormant cells, had enhanced functions in epithelial-mesenchymal transition (EMT), extracellular matrix (ECM), collagen formation, tumor inflammation siganure (TIS), and IL-10 signaling. Cluster 3 and 4 in active cells had enhanced DNA replication and tumor proliferation pathways, respectively. ConclusionThis study highlights the role of cancer cell characteristics and heterogeneity in the invasiveness of brain metastasis. Understanding these mechanisms can guide the development of more effective treatment strategies for breast cancer brain metastasis (BCBM) patients.

The Role and Mechanism of TEAD4 in Preimplantation Embryonic Development in Mice and Cattle

Tead4, a critical transcription factor expressed during preimplantation development, is essential for the expression of trophectoderm-specific genes in mice. However, the functional mechanism of Tead4 in mouse preimplantation development and its conservation across mammals remain unclear. Here, we report that Tead4 is a crucial transcription factor necessary for blastocyst formation in mice. Disruption of Tead4 through base editing results in developmental arrest at the morula stage. Additionally, RNA-seq analysis reveals dysregulation of 670 genes in Tead4 knockout embryos. As anticipated, Tead4 knockout leads to a decrease in trophectoderm genes Cdx2 and Gata3. Intriguingly, we observed a reduction in Krt8, suggesting that Tead4 influences the integrity of the trophectoderm epithelium in mice. More importantly, we noted a dramatic decrease in nuclear Yap in outside cells for Tead4-deficient morula, indicating that Tead4 directly regulates Hippo signaling. In contrast, bovine embryos with TEAD4 depletion could still develop to blastocysts with normal expression of CDX2, GATA3, and SOX2, albeit with a decrease in total cell number and ICM cell number. In conclusion, we propose that Tead4 regulates mouse blastocyst formation via Krt8 and Yap, both of which are critical regulators of mouse preimplantation development.

Long-read Transcriptome Landscapes of Primary and Metastatic Liver Cancers at Transcript Resolution

BackgroundThe liver is the sixth most common site of primary cancer in humans and is frequently colonized by metastases from cancers of other organs. Few studies have investigated the transcriptomic profiles of matched primary tumor and hepatic metastases of patients. Moreover, the read length of 100-200 bases in conventional short-read RNA sequencing is too short, which makes it difficult to directly infer the full-length transcript structure. To help develop effective treatments and improve survival, it is crucial to understand the complex and diverse molecular mechanisms of primary and metastatic liver cancers. MethodsNinety-five primary and secondary liver cancer patients who underwent hepatic resection were included with long-read sequencing isoform-sequencing and short-read RNA sequencing. We compared the transcriptome landscapes of primary and metastatic liver cancers and systematically investigated HCC, paired primary tumors and liver metastases, and matched non-tumor liver tissues. ResultsWe defined the full-length isoform-level transcriptome of human primary and metastatic liver cancers and identified isoform-level diversity in HCC and metastasis-associated transcriptome variations in metastatic liver cancers. Specific RNA transcripts and isoform switching events with clinical implications were profoundly discovered in liver cancer. Metastasis-specific transcripts that can predict the metastatic risk and identify the primary sites of cancers of unknown primary liver metastasis patients were defined. Additionally, we found that adjacent paracancerous liver tissues are abnormal and characterized the premetastatic immunological and metabolic alterations in the liver that favor the spread of cancer metastases. ConclusionsOur findings strongly highlight the powerfulness of full-length transcriptome profiling to yield novel biological insights into understanding the molecular basis of tumorigenesis and will further benefit the treatment of primary and metastatic liver cancers.

Unconventional Activation of IRE1 Enhances TH17 Responses and Promotes Neutrophilic Airway Inflammation

Treatment-refractory severe asthma manifests a neutrophilic phenotype associated with TH17 responses. Heightened unfolded protein responses (UPRs) are associated with the risk of asthma, including severe asthma. However, how UPRs participate in the deregulation of TH17 cells leading to this type of asthma remains elusive. In this study, we investigated the role of the UPR sensor IRE1 in TH17 cell function and neutrophilic airway inflammation. We found that IRE1 is induced in fungal asthma and is highly expressed in TH17 cells relative to naive CD4+ T cells. Cytokine (e.g. IL-23) signals induce the IRE1-XBP1s axis in a JAK2-dependent manner. This noncanonical activation of the IRE1-XBP1s pathway promotes UPRs and cytokine secretion by TH17 cells. Ern1 (encoding IRE1)-deficiency decreases the expression of ER stress factors and impairs the differentiation and cytokine secretion of TH17 cells. Genetic ablation of Ern1 leads to alleviated TH17 responses and airway neutrophilia in a Candida albicans asthma model. Consistently, IL-23 activates the JAK2-IRE1-XBP1s pathway in vivo and enhances TH17 responses and neutrophilic infiltration into the airway. Taken together, our data indicate that IRE1, noncanonically activated by cytokine signals, promotes neutrophilic airway inflammation through the UPR- mediated secretory function of TH17 cells. The findings provide a novel insight into the fundamental understanding of IRE1 in TH17-biased TH2-low asthma.

The evolution and mutational robustness of chromatin accessibility in Drosophila

The evolution of regulatory regions in the genome plays a critical role in shaping the diversity of life. While this process is primarily sequence-dependent, the enormous complexity of biological systems has made it difficult to understand the factors underlying regulation and its evolution. Here, we apply deep neural networks as a tool to investigate the sequence determinants underlying chromatin accessibility in different tissues of Drosophila. We train hybrid convolution-attention neural networks to accurately predict ATAC-seq peaks using only local DNA sequences as input. We show that a model trained in one species has nearly identical performance when tested in another species, implying that the sequence determinants of accessibility are highly conserved. Indeed, model performance remains excellent even in distantly-related species. By using our model to examine species-specific gains in chromatin accessibility, we find that their orthologous inaccessible regions in other species have surprisingly similar model outputs, suggesting that these regions may be ancestrally poised for evolution. We then use in silico saturation mutagenesis to reveal evidence of selective constraint acting specifically on inaccessible chromatin regions. We further show that chromatin accessibility can be accurately predicted from short subsequences in each example. However, in silico knock-out of these sequences does not qualitatively impair classification, implying that chromatin accessibility is mutationally robust. Subsequently, we demonstrate that chromatin accessibility is predicted to be robust to large-scale random mutation even in the absence of selection. We also perform in silico evolution experiments under the regime of strong selection and weak mutation (SSWM) and show that chromatin accessibility can be extremely malleable despite its mutational robustness. However, selection acting in different directions in a tissue-specific manner can substantially slow adaptation. Finally, we identify motifs predictive of chromatin accessibility and recover motifs corresponding to known chromatin accessibility activators and repressors. These results demonstrate the conservation of the sequence determinants of accessibility and the general robustness of chromatin accessibility, as well as the power of deep neural networks as tools to answer fundamental questions in regulatory genomics and evolution.

HSP90 inhibitor NVP-HSP990 alleviates rotavirus infection

Rotavirus (RV) infection is a significant cause of hospitalization and mortality in infants and young children. Although conventional symptomatic treatments usually appear effective, tens of thousands of infants and young children still die each year due to the absence of safe and effective anti-RV drugs. Heat shock protein 90 (HSP90) is usually required for efficient viral infection; however, due to unsatisfactory antiviral efficacy and toxicity, there has been no HSP90-targeting agents applied for clinical antiviral therapy currently. Here, we demonstrated that NVP-HSP990, a novel small-molecule HSP90 inhibitor with excellent oral bioavailability and brain penetration, was a potent inhibitor of RV infection with much bigger selectivity index (SI) than traditional HSP990 inhibitors. NVP-HSP990 potently inhibited RV replication in vitro without blocking infection establishment. NVP-HSP990 remarkably restored gene expressions of most KEGG pathways disturbed by RV infection in intestinal cells, except some inflammatory pathways (IL-17, TNF, etc.). To be noted, NVP-HSP990 significantly altered gene expressions in MAPK signaling pathway and inhibited RV-induced activation of MAPK as well as disruption of tight junctions in Caco-2 cells. More importantly, NVP-HSP990 effectively alleviated RV diarrhea, competently inhibited RV replication, and obviously prevented pathological lesions of intestine in BALB/c suckling mice. Therefore, our results suggested that NVP-HSP990 can be a promising antiviral drug candidate against RV infection.

Myosin 10 uses its MyTH4 and FERM domains differentially to support two aspects of spindle pole biology required for mitotic spindle bipolarity

Myosin 10 (Myo10) has the ability to link actin filaments to integrin-based adhesions and to microtubules by virtue of its integrin-binding FERM domain and microtubule-binding MyTH4 domain, respectively. Here we used Myo10 knockout cells to define Myo10s contribution to the maintenance of spindle bipolarity, and complementation to quantitate the relative contributions of its MyTH4 and FERM domains. Myo10 knockout HeLa cells and mouse embryo fibroblasts (MEFs) both exhibit a pronounced increase in the frequency of multipolar spindles. Staining of unsynchronized metaphase cells showed that the primary driver of spindle multipolarity in knockout MEFs and knockout HeLa cells lacking supernumerary centrosomes is pericentriolar material (PCM) fragmentation, which creates y-tubulin-positive acentriolar foci that serve as additional spindle poles. For HeLa cells possessing supernumerary centrosomes, Myo10 depletion further accentuates spindle multipolarity by impairing the clustering of the extra spindle poles. Complementation experiments show that Myo10 must interact with both integrins and microtubules to promote PCM/pole integrity. Conversely, Myo10s ability to promote the clustering of supernumerary centrosomes only requires that it interact with integrins. Importantly, images of Halo-Myo10 knock-in cells show that the myosin localizes exclusively within adhesive retraction fibers during mitosis. Based on these and other results, we conclude that Myo10 promotes PCM/pole integrity at a distance, and that it facilitates supernumerary centrosome clustering by promoting retraction fiber-based cell adhesion, which likely provides an anchor for the microtubule-based forces driving pole focusing.

Acute stress reshapes third-party punishment and help decisions: Behavioral evidence and neurocomputational mechanisms

People tend to intervene in others injustices by either punishing the transgressor or helping the victim. Injustice events often occur under stressful circumstances. However, how acute stress affects a third partys intervention in injustice events remains open. Here, we show a stress-induced shift in third parties willingness to engage in help instead of punishment by acting on emotional salience and central-executive and theory-of-mind networks. Acute stress decreased the third partys willingness to punish the violator and the severity of the punishment and increased their willingness to help the victim. Computational modeling revealed a shift in intervention severity bias from punishment toward help under stress. This finding is consistent with the increased dorsolateral prefrontal engagement observed with higher amygdala activity and greater connectivity with the ventromedial prefrontal cortex. A brain connectivity theory-of-mind network predicted stress-induced severity bias in punishment. Our findings suggest a neurocomputational mechanism of how acute stress reshapes third parties decisions by reallocating neural resources in emotional, executive and mentalizing networks to inhibit punishment bias and decrease punishment severity.
