Systematic Survey of Public Datasets for Behavioral Research in Invertebrate Models: Toward FAIR and Standardized Data Sharing

Behavioral datasets for invertebrate model organisms are rapidly expanding alongside automated imaging, tracking, and artificial intelligence (AI) based phenotyping, yet their technical structure and compliance with the Findable, Accessible, Interoperable and Reusable (FAIR) principles remain heterogeneous. We present a two-stage survey of openly available behavioural datasets for major invertebrate models Caenorhabditis elegans (C. elegans), Drosophila melanogaster (D. melanogaster), Galleria mellonella (G. mellonella), and planarians Schmidtea mediterranea (S. mediterranea) with larval zebrafish (Danio rerio) included as a vertebrate comparator. Stage 1 comprised a PRISMA-guided literature review (from 2015 to 2025) across indexed databases and complementary non-indexed sources, yielding 12 eligible publications describing 12 open behavioural datasets. Stage 2 independently screened and technically evaluated repository deposits (from June 2022 to July 2025), producing a final corpus of 20 datasets scored on a four-dimension ordinal rubric capturing usability, annotation richness, technical quality and AI-readiness. All extracted descriptors, repository search logs, and scoring sheets are released as public data records enabling full regeneration of figures and summary statistics. Across Stage 2 deposits, multimodality and open file formats were common, whereas interoperability and AI-readiness were most constrained by limited machine-readable metadata, weak raw-to-derived provenance, and sparse adoption of formal standards or ontologies. This Data Descriptor provides a reproducible, dataset-centred overview of behavioural resources for invertebrate models and practical guidance for FAIR-aligned publication, secondary biological analyses, and AI benchmarking.

Extracellular Matrix Proteins Changes in the Left Ventricular Unloading and Overloading after Myocardial Infarction

BackgroundThe cardiac extracellular matrix (ECM) is a dynamic scaffold that transmits and responds to forces that act on the heart during the cardiac cycle. While acute left ventricle (LV) unloading by percutaneous LV assist device (pLVAD) is now a therapeutic option, its impact on ECM is unknown. We hypothesize that the composition of LV ECM proteins changes in response to reduced wall stress with mechanical LV unloading. MethodsTen Yorkshire pigs underwent myocardial infarction, and one week later were subjected to either 2 hours of LV unloading with pLVAD or 2 hours of LV overloading by mechanically-induced acute aortic regurgitation. Non-ischemic remote myocardium was processed for ECM specific proteomics. Volcano plots were constructed to determine differentially expressed proteins between the groups. Gene ontology (GO) analysis was performed to identify associated molecular processes and biological functions. Immunofluorescence microscopy was performed to validate differential protein expression. ResultsOf the 986 proteins analyzed, 39 were significantly differentially expressed between overloaded and unloaded myocardium. GO analysis by molecular function revealed that differences tending towards RNA binding and lipid binding proteins. Analysis by biological process showed that cell differentiation, vesicle transport, and programmed cell death were the processes most affected. Staining for three of the identified differentially expressed proteins had results congruent with proteomic analysis. ConclusionsThere were significant differences in the protein composition of the cardiac ECM between acutely unloaded and overloaded myocardium, suggesting that it actively responds to altered LV load.
