About - WntHub

Overview

WntHub is a panel-based interactive platform for exploring Wnt signaling pathway genes across genomic, transcriptomic, epigenomic, proteomic, and clinical dimensions. It integrates data from GTEx, Human Protein Atlas, TCGA, CELLxGENE, Tahoe100m, ENCODE, ChIP-Atlas, LINCS L1000, and more into a unified sidebar + tabbed interface with interactive Plotly.js charts, an IGV.js genome browser, D3 force-directed co-expression networks, and an AI-powered research assistant grounded in 23K+ Wnt publications.

The platform covers 91 Wnt-pathway genes, organised into eight functional categories: ligands (all 19 WNTs), Frizzled receptors (FZD1–10), co-receptors (LRP5/6) and non-canonical receptors (ROR1/2, RYK), the R-spondin axis (RSPO3, LGR4/5/6, RNF43, ZNRF3), secreted antagonists (DKK1–4, SFRP1/2/4/5, FRZB, WIF1, SOST, KREMEN1/2, NOTUM) and secretion machinery (PORCN, WLS), the destruction complex (APC, AXIN1/2, GSK3B, CSNK1A1) with cytoplasmic transducers (CTNNB1, DVL1–3, CSNK1E) and feedback inhibitors (NKD1/2, FRAT1/2), the planar-cell-polarity / Rho axis (VANGL1/2, PRICKLE1/2, CELSR1–3, DAAM1/2, RHOA, RAC1, CDC42), and the transcription layer (TCF7, TCF7L1/2, LEF1, NLK, TLE1, CTNNBIP1) with canonical target genes (MYC, CCND1).

Cross References tab: Cross Refs

Dynamic links to 30+ external databases (GeneCards, UniProt, NCBI, Ensembl, KEGG, Reactome, ClinVar, OMIM, etc.).

Good for: Finding a gene in other databases, jumping to external resources.

AI Research Assistant

RAG-powered chatbot grounded in 23,323 Wnt pathway publications (31,773 text chunks). Accessible via the floating widget from any tab. Supports multi-turn conversation with history, markdown rendering, and adjustable temperature.

Architecture

Query Classifier: Qwen3-14B pre-classifies every query as site, hybrid, or science. Site questions (e.g. "which species?", "where can I find variant data?") skip the RAG pipeline entirely and are answered in ~1-2s from platform knowledge. Science questions proceed through the full RAG pipeline. Hybrid questions get both
Embeddings: BAAI/bge-base-en-v1.5 (768-dim), Neon PostgreSQL + pgvector HNSW
Search: Hybrid — vector similarity (70%) + BM25 (30%), 100 candidates
Reranking: Qwen3-Reranker (4B/8B) with quality threshold
LLM: Qwen3-Next-80B MoE (default) · Qwen3-235B (deep analysis)
Response Types: Concise (3K), Overview (5K), Interpretive (10K), Deep (10K)

Data Integration

The AI assistant can optionally include structured experimental data from the site alongside literature context. Selectable data sections:

Genomic: Gene structure, ClinVar variants, ChIP-Atlas TF peaks
HPA / DepMap / CELLxGENE / Tahoe: Tissue and cancer cell line expression
Pathways: MSigDB pathway enrichment (KEGG, Reactome, GO, Hallmark)
GTEx Correlations: Top co-expressed genes per tissue (Spearman r ≥ 0.5). Automatic pairwise lookup when multiple genes are queried
TCGA: Tumor expression (log₂ TPM) across 33 TCGA cancer types with tissue-aware cancer detection (e.g., "liver cancer" → LIHC)

Changelog

May 11, 2026 — wnthub.org Launch & Engine Polishing

Custom Domain Live: WntHub now serves at https://wnthub.org. Apex A record → Netlify load balancer + www CNAME, Let’s Encrypt cert auto-provisioned, Force HTTPS enabled. The auto-generated aesthetic-cascaron-f8669f.netlify.app URL keeps working — Netlify auto-301-redirects it to wnthub.org — so any grant-application links already circulating remain valid. Pre-submission inquiry letter (NAR Database Issue) updated to the live URL.
Site-Neutral Engine Identifiers: Two-step engine refactor moved every WntHub-specific identifier (WNT_GENES, WNT_SET, WNT_SET_HASH, _wntSetHash, wnt_gene/wnt_adj/wnt_edges/wnt_df local variables, load_wnt_expression(), etc.) into neutral names (GENES, GENE_SET, GENE_SET_HASH, _geneSetHash, pathway_gene, gene_adj, ...) across 27 engine scripts. WNT_GENES kept as a one-line alias so site-specific code (the AI-summary toolchain) keeps working unchanged. Future cherry-picks between WntHub and CABase now auto-merge instead of needing manual conflict resolution.
Site-Config-Driven Identity: scripts/pipelines/config.py now reads site-config.json at import and re-exports SITE_NAME, GENE_SET_LABEL, GENE_SET_FULL, DATA_SUFFIX — engine code never needs the literal “WntHub” / “Wnt” / “Wnts” strings hardcoded.
Automated Site Stats: Two new engine scripts (scripts/build_site_stats.py + scripts/render_site_text.py) compute every data-derived number on the site (gene count, GTEx subtissues, TCGA KM curves, PRECOG records, iPTMnet sites, CELLxGENE counts, LINCS records, Tahoe drug-perturbation counts, RAG corpus size, ...) and substitute them into HTML/JS via declarative <span data-stat="key"> markers. Wired into master_rebuild_all.sh as Step 18, after data pipelines and before the _site/ rsync. Manual overrides via site_stats_overrides.json for values that can’t be derived from on-disk data (e.g. RAG corpus counts that live in the Neon Postgres DB). Eliminates the stale-number drift that has historically dogged about/index page edits.

May 6, 2026 — Pathway Coverage Doubled (46 → 91 genes)

Gene Set Expanded: The curated Wnt-pathway set grew from 46 to 91 genes, organised into eight functional categories. Selection driven by recurrence across 70 MSigDB Wnt-related pathway sets. New additions span the secreted-antagonist arm (DKK1–4, SFRP1/2/4/5, FRZB, WIF1, SOST, KREMEN1/2), the R-spondin / RNF43 / LGR stem-cell axis (RSPO3, LGR4/5/6, RNF43, ZNRF3), Wnt secretion machinery (PORCN, WLS, NOTUM), CK1 destruction-complex isoforms (CSNK1A1, CSNK1E), non-canonical receptors (ROR1/2, RYK), planar-cell-polarity core (VANGL1/2, PRICKLE1/2, CELSR1–3, DAAM1/2), Rho GTPases (RHOA, RAC1, CDC42), and transcription-layer regulators (NLK, TLE1, CTNNBIP1). WNT11, previously dropped due to a hand-transcription error, is now included — bringing all 19 human WNT ligands into the set.
Pipelines Re-run End-to-End: All 18 ingestion steps in scripts/pipelines/master_rebuild_all.sh were executed against the expanded set with cache-aware skip logic, so existing per-gene API calls (ChIP-Atlas, iPTMnet, ProteomicsDB) and per-gene LINCS GCTX extractions were re-used; only the 45 new genes hit the external services. Co-expression network JSONs now embed a _wntSetHash fingerprint and self-invalidate when the gene set changes.
Downstream Counts Refreshed: ClinVar 84,249 variants across 91 genes; ChIP-Atlas TF universe 1,086 → 1,328 chromatin-associated factors; TCGA Kaplan-Meier curves 1,451 → 2,898; PRECOG records ~5K → ~9.4K (adult + ICI + pediatric combined); LINCS L1000 genetic 45,868 → 103,206 records (View 1) and 59,533 → 97,680 (View 2); Tahoe-100M perturbations 217,915 → 458,122 records; iPTMnet 1,118 → 1,875 PTM sites; co-expression network files 2,144 → 4,269.
Engineering Hardening: Three drifted hand-typed gene lists (in build_survival_json.py, build_network_json.py, gtex/06_build_site_correlations.py) consolidated to import from a single source (scripts/pipelines/config.py); the duplicate gtex/04_network_json.py was reduced to a deprecation stub. LINCS pipelines gained per-gene skip-if-exists logic with --force override, with cached per-gene files folded into the combined output so subsequent runs touch only new genes.
HPA Source-Schema Fixes (caught en route): HPA renamed the FANTOM5 sTPM column case (“Scaled Tags Per Million” → “Scaled tags per million”) and retired the rna_cancer.tsv.zip endpoint; pipeline definitions in hpa/01_retrieve_and_filter.py updated accordingly. The DepMap portal is currently 403’ing public file downloads; CCLE expression now resolves through a local snapshot symlinked into data/_raw/DepMap/.

April 14, 2026 — GTEx Direct Build & Documentation Refresh

GTEx Source Unified: The RNA-Seq tab's GTEx panels (bar + 4 radar charts) now consume the same in-house GTEx V10 build that powers the Correlation/Network analyses. The HPA-redistributed GTEx nTPM file is no longer used anywhere on the site. Pipeline: scripts/pipelines/gtex/08_build_true_gtex_expression.py (GTEx V10 parquet → per-subtissue median TPM → nTPM, ≥20 samples/subtissue, 55 subtissues)
Manuscript Data Table Refresh: Updated docs/manuscript-data-table.2026-04-14.xlsx supersedes the 2026-03-23 version. GTEx row reclassified as direct/in-house; added rows for Tahoe-100M perturbations, ENCODE/UCSC regulatory tracks, and HPA subcellular localization; LINCS L1000 split into three rows (compounds, "what affects gene", "what gene affects"); LINCS compound count corrected to 12,735 filtered uniques
New Provenance Document: docs/data-generation-report.md — per-plot/per-table provenance covering every panel in every sidebar tab, from upstream database through pipeline script to rendered value
About Page Counts Corrected: ChIP-Atlas factors 1,086 → 1,846; Tahoe scRNA-Seq "116M cells" → "2.3M DMSO cells (77M total)"; CELLxGENE "38 tissues · 187 cell types" → actual 62 tissues · 806 cell types; co-expression network files 2,088 → 2,144

March 24, 2026 — Tahoe-100M Perturbations & iPTMnet Improvements

Tahoe-100M Perturbations: New sub-tab on the Perturbations page integrating single-cell RNA-seq drug response data from the Tahoe-100M dataset (~77M cells, 379 drugs, 50 cell lines, 14 plates). Pseudobulk replicate approach: cells split into 25- or 50-cell replicates, Wilcoxon rank-sum test vs matched DMSO replicates, BH FDR correction. 217,915 records across 32 genes (84.3% BH-significant). Waterfall chart, MOA enrichment, and filterable table with p-values, replicate counts, and confidence tiers
Info Tooltips: Added contextual info icons across all 10 site-wide data tables explaining statistical metrics, column meanings, and data sources. Floating tooltip design escapes all CSS stacking contexts
Tab Persistence Fix: Fixed Plotly charts going blank when navigating away from a tab and returning. Charts now re-render from cached data on tab switch
iPTMnet Plot: Y-axis now uses iPTMnet score (instead of known enzymes), circle size represents number of enzymes. Hover tooltip includes enzyme list and publication count
iPTMnet Table: Rebuilt with TableViewer for sorting, filtering, and export. Added Score and Position columns, enzyme names link to UniProt, dropdown filters on Type/Score/Known/Evidence
Mol* Viewer Fix: Fixed issue where switching from PTM overlays to structure property themes would fail. Viewer now reloads cleanly when transitioning between overlay categories
