#GSEA
Step 3: Pathway-level aggregation

Feature noise limits statistical power. We aggregated 30,000+ features using #GSEA & structured knowledge frameworks.
This transformed raw data into functional #pathways-mapping downstream pathology and quantification of rescue.

GSEA is one of the highly cited methods (> 50K! ) for gene set enrichment analysis. Do you really understand it?

They wanted a chart similar to a Gene Set Enrichment Analysis (GSEA), but they needed to summarize the effect across many GO terms at once, in a simpler and easier to understand way. Hence, the lollipop chart in this notebook: new.observablehq.com/@neurogenomi...

The DEGs were involved in immune dysregulation, neuroinflammation and neurological dysfunction, and metabolic dysregulation. GSEA analysis revealed 23 canonical pathways with FDR below 0.10.

Conclusion: Our findings revealed higher cumulative

So... day 2 is already over? 🫣

Talks, packed rooms, GSEA, meetings, posters, drinks, football... yes, it has been full! 😄

Unless you're feeling the World Cup blues... sleep well! Tomorrow morning some of us are going plogging before Mehmet Somel's plenary session. 🏃‍♀️

RANKOR: Direct Drug Prioritization from Bulk and Single-Cell Transcriptomic Signatures
Background Prioritizing therapeutics from transcriptomic data remains a key challenge in precision medicine. Signature reversal approaches, most commonly implemented through Gene Set Enrichment Analysis (GSEA), have been widely used to match disease signatures to candidate drugs. However, enrichment-based methods can be sensitive to noise and are restricted to previously profiled compounds Methods We developed RANKOR, a machine-learning framework designed to rank candidate drugs directly from transcriptomic signatures. Rather than predicting full expression profiles, RANKOR learns structured latent representations of transcriptional responses alongside chemical structure, enabling prioritization from standardized signatures derived from disease states or treatment perturbations. The framework is applicable to both bulk and single-cell transcriptomic data. Results Across large-scale perturbational datasets, RANKOR achieved consistently lower median ranks than similarity- and distance-ba
