Abstract

BackgroundThe network biology of disease-gene association provides a holistic framework to decipher the intrinsic complexity of disease signaling pathways into cellular communication level. Different types of studies including large-scale genome-wide association, multifactor dimensional reduction analysis, whole genome, or exome-based sequencing strategies of diseases are striving to connect genes to diseases. Indeed, these approaches have had some accomplishments, but the cellular communication level needs a more streamlining outcome to understand the mechanistic impact of context. The higher-order combination of disease-gene interaction has a great potential to decipher the intricateness of diseases. The molecular interaction pattern of diseases at the genomic and proteomic level offers a revolutionized platform not only to understand the complexity of particular disease modules and pathways but also leading towards design novel therapeutics. ResultsThe enrichment and topology analysis was performed by JEPETTO a plugin of Cytoscape software. We identified the chronic myeloid leukemia (CML) disease signaling pathways that appeared first in the ranking order based on XD-score among the bone, breast, and colon genes set and second at kidney and liver. This result validates the highest proximity between CML and five cancerous tissue gene set clusters. The topology analysis also supports the results while (p<0.0001) is considered to be extremely significant between CML and fives cancerous tissues genes set. Enrichment analysis identified that abl-gene acts as an overlapping node which is the major gene for inducing various mutations in CML. Amazingly, we identified 56 common path expansion/added genes among these five cancerous tissues which can be considered the direct cofactors of CML disease. By relative node degree, resolution, possible ligand, stoichiometry, Q-mean, and Z-score analysis we found 11 hubs proteins like SMAD3, GRB2, TP53, SMAD4, RB1, HDAC1, RAF1, ABL1, SHC1, TGFBR1, RELA which can be regarded for further drug target identification. ConclusionsOur proposed network analysis reflects on the gene set interaction pattern of disease signaling pathways of humans. The integrated multidrug computational and experimental approaches boost up to improve the novel drug target approach. Besides, such a trove can yield unprecedented insights to lead to an enhanced understanding of potential application both in drug target optimization and for drug dislodging.

spatialMET: an open and scalable framework for spatial metabolomics analysis

Mass spectrometry imaging (MSI) enables spatially resolved metabolomics in intact tissue sections, but analysis remains challenging at scale. Existing MSI workflows often require users to combine multiple software tools, while others rely on proprietary vendor software that limits interoperability and reproducibility. To address these challenges, we developed spatialMET, an open-source framework that provides an end-to-end workflow for MSI analysis. spatialMET provides a unified platform for preprocessing, spatial domain detection, and visualization. Downstream analyses include differential abundance testing, spatial autocorrelation and gradient analysis, dimensionality reduction, and correlation network analysis. Spatial domain detection uses hcdist, a C-based hierarchical clustering implementation that substantially reduces runtime and memory use relative to existing R-based approaches. spatialMET can be run through an interactive R Shiny application or as a standalone command-line workflow for larger datasets or high-performance computing environments. Applied to mouse small cell lung cancer MALDI-MSI data containing 284,673 pixels, spatialMET identified tumor-associated, stromal, and adjacent lung spatial domains that aligned with matched histology. Differential abundance analysis identified 117 m/z features that differed between tumor and stromal regions, while spatial autocorrelation analyses revealed spatially structured abundance patterns. Applying spatialMET to mouse lung adenocarcinoma data from an entire lung lobe containing 338,477 pixels further demonstrated scalability and captured spatial heterogeneity across tumor and surrounding lung tissue. In summary, spatialMET provides a scalable, open-source framework for end-to-end spatial metabolomics analysis, and it is distributed as a Docker container for reproducible deployment. Source code and installation instructions are available at https://github.com/biodatalab/spatialMET.

Probing the transcriptome response to shivering in skeletal muscle using a multilayered bioinformatics approach

Cold acclimation holds therapeutic potential for improving metabolic health. We previously demonstrated that repeated cold-induced shivering enhances insulin sensitivity in humans. However, the molecular pathways that underlie the skeletal muscle shivering response, and how these relate to beneficial physiological effects, remain poorly understood. In this study, we combined complementary bioinformatics approaches to allow in-depth analysis of the transcriptomic response of human skeletal muscle to repeated shivering. We identified a robust transcriptional signature and show a sex-specific component in the shivering skeletal muscle response, which seemed to diminish following cold adaptation. Our findings provide mechanistic insights into cold-induced muscle adaptations, shed light on potential interesting molecular targets for further investigation, and emphasize the importance of including both sexes in future cold acclimation studies.

An Information Geometry approach to model topological trajectories and Gene Expression Radius from UMAP geometry.

Understanding the relationship between gene expression dynamics and cellular identity remains a central challenge in single cell biology. Here, we introduce a novel computational and mathematical framework that integrates information geometry, fuzzy topology, and UMAP analysis to model gene expression landscapes derived from single cell RNA sequencing data. We formalize gene expression data as a fuzzy topological space, where interactions between expression points are governed by probabilistic distributions inspired by manifold learning approaches such as UMAP. Within this framework, we define an information geometric structure through a Fisher metric induced by these distributions, enabling the computation of geodesic trajectories that capture cellular differentiation processes. A key contribution of this work is the derivation of analytical conditions, expressed as expression radius formulas, that characterize local neighborhoods in gene expression space. These conditions allow for the identification of genes associated with stem cell states and predictions in transitional cell types in future work. Application of the proposed framework to single cell datasets reveals biologically meaningful gene sets enriched in key regulatory pathways and transcription factors, demonstrating the capacity of our approach to uncover latent structure in complex gene expression data. Our results suggest that integrating differential geometry with statistical learning theory offers a powerful paradigm for modeling genotype and phenotype relationships and cellular state transitions, with potential implications for precision medicine and systems biology.
