Spatial Multi-Omics Analysis Pipeline

Comprehensive biological interpretation of spatial omics data. Transforms spatially variable genes (SVGs), domain annotations, and tissue context into actionable biological insights.

KEY PRINCIPLES :

1. Report-first approach - Create report file FIRST, then populate progressively
2. Domain-by-domain analysis - Characterize each spatial region independently before comparison
3. Gene-list-centric - Analyze user-provided SVGs and marker genes with ToolUniverse databases
4. Biological interpretation - Go beyond statistics to explain biological meaning of spatial patterns
5. Disease focus - Emphasize disease mechanisms and therapeutic opportunities when disease context is provided
6. Evidence grading - Grade all evidence as T1 (human/clinical) to T4 (computational)
7. Multi-modal thinking - Integrate RNA, protein, and metabolite information when available
8. Validation guidance - Suggest experimental validation approaches for key findings
9. Source references - Every statement must cite tool/database source
10. English-first queries - Always use English terms in tool calls

When to Use This Skill

Apply when users:

• Provide spatially variable genes from spatial transcriptomics experiments
• Ask about biological interpretation of spatial domains/clusters
• Need pathway enrichment of spatial gene expression data
• Want to understand cell-cell interactions from spatial data
• Ask about tumor microenvironment heterogeneity from spatial omics
• Need druggable targets in specific spatial regions
• Ask about tissue zonation patterns (liver, brain, kidney)
• Want to integrate spatial transcriptomics + proteomics data

NOT for : Single gene interpretation (use target-research), variant interpretation, drug safety, bulk RNA-seq, GWAS analysis.

Evidence Grading

Analysis Phases Overview

Phase 0: Input Processing & Disambiguation (ALWAYS FIRST)

Resolve tissue/disease identifiers, establish analysis context. Get MONDO/EFO IDs for disease queries.

• Tools: OpenTargets_get_disease_id_description_by_name, OpenTargets_get_disease_description_by_efoId, HPA_search_genes_by_query

Phase 1: Gene Characterization

Resolve gene IDs, annotate functions, tissue specificity, subcellular localization.

• Tools: MyGene_query_genes, UniProt_get_function_by_accession, HPA_get_subcellular_location, HPA_get_rna_expression_by_source, HPA_get_comprehensive_gene_details_by_ensembl_id, HPA_get_cancer_prognostics_by_gene, UniProtIDMap_gene_to_uniprot

Phase 2: Pathway & Functional Enrichment

Identify enriched pathways globally and per-domain. Filter FDR < 0.05.

• Tools: STRING_functional_enrichment (PRIMARY), ReactomeAnalysis_pathway_enrichment, GO_get_annotations_for_gene, kegg_search_pathway, WikiPathways_search

Phase 3: Spatial Domain Characterization

Characterize each domain biologically, assign cell types from markers, compare domains.

• Tools: Phase 2 tools + HPA_get_biological_processes_by_gene, HPA_get_protein_interactions_by_gene

Phase 4: Cell-Cell Interaction Inference

Predict communication from spatial patterns. Check ligand-receptor pairs across domains.

• Tools: STRING_get_interaction_partners, STRING_get_protein_interactions, intact_search_interactions, Reactome_get_interactor, DGIdb_get_drug_gene_interactions

Phase 5: Disease & Therapeutic Context

Connect to disease mechanisms, identify druggable targets, find clinical trials.

• Tools: OpenTargets_get_associated_targets_by_disease_efoId, OpenTargets_get_target_tractability_by_ensemblID, OpenTargets_get_associated_drugs_by_target_ensemblID, clinical_trials_search, DGIdb_get_gene_druggability, civic_search_genes

Phase 6: Multi-Modal Integration

Integrate protein/RNA/metabolite data. Compare spatial RNA with protein detection.

• Tools: HPA_get_subcellular_location, HPA_get_rna_expression_in_specific_tissues, Reactome_map_uniprot_to_pathways, kegg_get_pathway_info

Phase 7: Immune Microenvironment (Cancer/Inflammation only)

Classify immune cells, check checkpoint expression, assess Hot vs Cold vs Excluded patterns.

• Tools: STRING_functional_enrichment, OpenTargets_get_target_tractability_by_ensemblID, iedb_search_epitopes

Phase 8: Literature & Validation Context

Search published evidence, suggest validation experiments (smFISH, IHC, PLA).

• Tools: PubMed_search_articles, openalex_literature_search

See phase-procedures.md for detailed workflows, decision logic, and tool parameter specifications per phase.
