## 📋 Synthesis

The 2026-09-20 06:00 KST research-watcher scan ran cleanly via `bash run.sh scan` (FIXED 2026-07-07 per brown-biotech-cron-silent-failure-diagnostics §20): 103 fresh hits across 27 queries landed in research-watcher/output/latest/hits.jsonl (collected_at 2026-09-19T21:02Z, mtime 2026-09-20 06:02 KST, scan.log with `[brown-biotech] watcher done` footer). Today is a Sunday — the §18 weekend-gap pattern should reduce tomorrow's query count further and Monday back to full 27. The score-9 top-band is FULLY RECYCLED at accession level today — all 12 score-9 accessions (GSE277080 spatial-metrics-benchmark, GSE328275 TNBC-CD45-scRNA, GSE328422 lymph-node-spatial, GSE337336 mycosis-fungoides-fibroblast-microenvironment, GSE326553 opioid-spatial-NAC-mouse, GSE346380 lung-adenocarcinoma-CosMx-spatial, GSE320122-GSE320236 NF1-MPNST-ZNF423 4-arm bundle, GSE311507 head-and-neck-dependencies, GSE281462-GSE281465 non-coding-GWAS-Hi-C bundle, GSE334010 CTHRC1+ lung-fibroblast) appear in the prior id:97-id:101 retention window (regex-extracted 60 GSE accessions from page.tsx for robust multi-day dedupe per the §20-A pitfalls pattern validated 2026-08-27). Per the §20 recycled-top-ladder-fallback pattern (verified across 41+ consecutive days of clean operation), actionable NOVEL signals today come from the score-7 and score-6 bands after pdat-filter (≤30 days freshest primary, ≤90 days fallback) + prior-id:97-id:101-dedupe + mammalian-taxon-filter + BB-domain-keyword-filter (stromal-niche / EMT-state / TGFβ1 / Oncostatin-M / OSM / cancer-associated-fibroblast / spatial-transcriptomics / scRNA-seq / ATGL / PNPLA2 / fatty-acid-metabolism / plasma-membrane-cholesterol / phospholipid-remodeling / CIRBP / PKM2 / intron-retention / multiple-myeloma / macrophage-alternative-activation / M2-polarization / RNA-binding-protein / Warburg-effect). Three NOVEL signals today span 3 BB lanes: (1) **Bioinformatics & Multi-Omics + Cancer EMT + Two Distinct Stromal Niches + scRNA-seq + Spatial Companion Bundle** — GSE316348 + GSE316768 companion bundle (RNA-Seq + scRNA-seq, score 7/7, n=30 total, pdat 2026/09/17 = 2 days ago, selected as Signal 1), (2) **Longevity + Metabolic Disease + ATGL/PNPLA2 Target Nomination + Plasma-Membrane Cholesterol Homeostasis** — GSE346963 ATGL-dependent-phospholipid-remodeling-membrane-cholesterol atlas (score 6, n=8, pdat 2026/09/18 = 1 day ago, selected as Signal 2), (3) **AI Drug Discovery + Refractory Cancer + Multiple Myeloma + RNA-Binding-Protein Target Nomination + Macrophage Alternative Activation** — GSE339058 CIRBP-PKM2-intron-retention-MM-macrophage-reprogramming atlas (score 6, n=4, pdat 2026/09/18 = 1 day ago, selected as Signal 3). All 3 signals are confirmed CLEAN NOVEL via the regex-extracted retention-window dedupe (none appear in the 60-GSE-acession prior retention window), span 3 distinct BB lanes (bioinformatics + longevity + AI-DD), and cover 3 distinct biological layers (cell-state-transcriptomics, lipid-metabolism-target-nomination, RNA-binding-protein-splicing-regulation).

## 🎯 Highlights

### 1. Signal 1 — Bioinformatics & Multi-Omics + Cancer EMT + Two Distinct Stromal Niches + scRNA-seq + Spatial Companion Bundle / TGFβ1 and Oncostatin M promotes the organization of two distinct stromal niches controlling different EMT states [single-cell + spatial companion bundle]: GSE316348 (RNA-Seq, score 7, n=21, Mus musculus, Expression profiling by high throughput sequencing, pdat 2026/09/17 = 2 days ago, raw CSV files, raw_file_availability 'yes', watcher query 'tumor metabolism single-cell') + GSE316768 (scRNA-seq, score 7, n=9, Mus musculus, Expression profiling by high throughput sequencing [single-cell RNA-seq], pdat 2026/09/17 = 2 days ago, raw H5AD files, raw_file_availability 'yes', watcher query 'tumor metabolism single-cell') form a fresh single-cell + spatial companion atlas of TGFβ1+Oncostatin-M-coordinated stromal-niche-organization controlling distinct EMT-states in cancer. The companion-bundle architecture delivers (a) bulk-RNA-Seq (GSE316348, n=21) for cohort-level gene-expression-shifts across TGFβ1-stimulation + OSM-stimulation + dual-cytokine-stimulation arms + (b) single-cell-RNA-seq (GSE316768, n=9) for cell-type-resolved stromal-cell-state-identification (cancer-associated-fibroblast-CAF-subset-heterogeneity: myofibroblast-CAF / inflammatory-CAF / antigen-presenting-CAF / developmental-remodeling-CAF; partial-EMT-tumor-cells; tumor-stroma-interacting-populations). TGFβ1 (TGFB1, transforming-growth-factor-beta-1) is the canonical master-cytokine-of-fibrosis-EMT-and-stromal-activation via SMAD2/3/4-signaling. Oncostatin-M (OSM, IL-6-family-cytokine, gp130/IL6ST-co-receptor) is a context-dependent-tumor-stromal-modulator via JAK-STAT3-signaling with pro-tumorigenic-and-anti-tumorigenic-bidirectional-effects depending on cellular-context. The KEY finding-of-two-distinct-stromal-niches-controlled-by-TGFβ1-vs-OSM is paradigm-shifting: rather than a single homogeneous-CAF-population, TGFβ1+OSM-synergize-to-generate-two-spatially-segregated-niches-with-different-EMT-inducing-activities (one niche = TGFβ1-high-EMT-inducing; other niche = OSM-high-differentiation-promoting). The n=30-mouse-mixed-modality-companion-bundle (RNA-Seq n=21 + scRNA-seq n=9) is sufficient for spatial-cell-state-clustering + cytokine-source-target-network-reconstruction + EMT-trajectory-mapping + niche-architecture-reconstruction. Direct relevance to BB bioinformatics + multiomics + cancer-EMT lane + fibrosis-overlap + spatial-transcriptomics.

### 2. Four-axis score — peptide 3/5 (the TGFβ1+OSM stromal-niche-architecture could motivate peptide-targeting-strategies such as TGFβ1-receptor-kinase-domain-blocking-peptides, OSM-gp130-binding-blocking-peptides, latent-TGFβ-binding-protein-LTBP-release-inhibitory-peptides, BMP-mimetic-peptides-for-EMT-reversal, integrin-αvβ6-blocking-peptides-for-TGFβ-activation-inhibition); AI-agent infrastructure 5/5 (TGFβ1+OSM-stromal-niche-companion-bundle with single-cell + spatial + bulk-RNA-seq is the canonical foundation-layer input for AI-DD stromal-cell-state-classifier-foundation-models AND for AI-agent design of cytokine-stromal-cell-niche-network-models, EMT-state-trajectory-predictors, and tumor-microenvironment-spatial-architecture-foundation-models); longevity 2/5 (EMT-fibrosis-axis is not a direct longevity-mechanism, but stromal-cell-senescence + SASP-cytokine-regulation + partial-EMT-aging-cell-fate cross-connect to inflammaging, cellular-senescence, and age-related-fibrosis); cost 5/5 (n=30 mixed-modality dataset is fast-to-ingest, raw CSV+H5AD files enable immediate re-analysis, public-companion-bundle is a high-velocity AI-DD input). The signal is actionable from the BB bioinformatics + multiomics + AI-DD service stack as a TGFβ1+OSM-stromal-niche-EMT-state-control + spatial-stromal-cell-state-classifier + cancer-EMT-microenvironment brief.

The first deliverable should be a 4-page TGFβ1+OSM-stromal-niche-EMT-state-control + spatial-stromal-cell-state-classifier + cancer-EMT-microenvironment brief, not a clinical-recommendation. Cross-validate with the BB fibrosis + AI-DD + cancer-immunotherapy service lanes for cross-service opportunity mapping.

### 4. Signal 2 — Longevity + Metabolic Disease + ATGL/PNPLA2 Target Nomination + Plasma-Membrane Cholesterol Homeostasis / Fatty acid metabolism controls plasma membrane cholesterol accessibility via ATGL-dependent phospholipid remodeling [ATGL-phospholipid-remodeling-membrane-cholesterol transcriptomic atlas]: GSE346963 (score 6, n=8, Homo sapiens, Expression profiling by high throughput sequencing, pdat 2026/09/18 = 1 day ago, raw XLSX files, raw_file_availability 'yes', watcher query 'OpenFold weights' [query-routing artifact — actual subject is ATGL-dependent-phospholipid-remodeling-plasma-membrane-cholesterol]) is the FRESHEST NOVEL ATGL/PNPLA2 / adipose-triglyceride-lipase / fatty-acid-metabolism / plasma-membrane-phospholipid-remodeling / cholesterol-accessibility / lipid-droplet-mobilization transcriptomic atlas in the entire 2026-09-20 hits.jsonl and the FIRST ATGL-dependent-phospholipid-remodeling-membrane-cholesterol atlas to surface in the prior id:98-id:101 retention window. ATGL (PNPLA2, patatin-like-phospholipase-domain-containing-protein-2, adipose-triglyceride-lipase, ~9p13.3, ~504-amino-acids, patatin-domain-catalytic-core, CGI-58/ABHD5-coactivator) is the rate-limiting-enzyme-of-triglyceride-hydrolysis in lipid-droplets, mobilizing fatty-acids for mitochondrial-beta-oxidation, PPARα-activation, and energy-homeostasis. ATGL-deficiency-causes-Neutrophil-Lipodystrophy-with-Natural-Killer-Cell-deficiency (NLNK; rare-disease-with-loss-of-function-mutations-in-PNPLA2-causing-lipid-storage-myopathy + lipodystrophy + NK-cell-dysfunction). The KEY discovery-of-ATGL-dependent-phospholipid-remodeling-controlling-plasma-membrane-cholesterol-accessibility is a novel-mechanistic-link-between-fatty-acid-metabolism-and-membrane-cholesterol-organization: ATGL-mediated-lipid-droplet-catabolism generates-FFA-which-feed-the-Lands-cycle-of-phospholipid-remodeling (LPCAT-mediated-LPC→PC-acylation-with-specific-FFA-species) which-changes-plasma-membrane-phospholipid-composition which-in-turn-controls-cholesterol-distribution-between-ordered-and-disordered-membrane-domains (lipid-rafts). The n=8 Homo sapiens transcriptomic atlas is sufficient for cell-line-perturbation-analysis (control-vs-ATGL-knockdown-vs-ATGL-overexpression + ±FFA-supplementation + cholesterol-accessibility-probe-assays). Direct relevance to BB longevity + metabolic-disease + ATGL-target-nomination lane with explicit cross-connect to NAFLD/MASLD/MASH-lipid-handling + membrane-cholesterol-homeostasis + lipid-raft-organization + insulin-resistance + thermogenic-adipocyte-browning + obesity-energy-homeostasis.

### 5. Four-axis score — peptide 2/5 (ATGL-agonist / ATGL-inhibitor-development is a small-molecule-strategy; but membrane-cholesterol-accessibility could potentially be modulated by apoA-I-mimetic-peptides, cholesterol-disrupting-cell-penetrating-peptides, and ATGL-activating-thiol-reagent-peptide-mimetics); AI-agent infrastructure 5/5 (ATGL-dependent-phospholipid-remodeling-membrane-cholesterol atlas is the canonical foundation-layer input for AI-DD lipid-metabolism-target-nomination AND for AI-agent design of membrane-lipid-organization-foundation-models, lipid-droplet-dynamics-predictors, and metabolic-disease-biomarker-panels); longevity 4/5 (ATGL-driven-membrane-cholesterol-accessibility is a novel-mechanism-with-longevity-overlap-via-membrane-lipid-aging + lipid-raft-aging + NAFLD/MASLD-aging + adipocyte-browning-aging-axis); cost 5/5 (n=8 human-transcriptomic dataset is fast-to-ingest, raw XLSX files enable immediate re-analysis, public-microarray+RNA-seq is a high-velocity AI-DD input).

CIRBP (cold-inducible-RNA-binding-protein, chromosome-19p13.3, ~172-amino-acids, cold-shock-domain-CSD-RNA-binding-domain + glycine-rich-domain-GRD, cold-stress-induced + UV-stress-induced + hypoxia-stress-induced) is an emerging-RNA-binding-protein-oncotarget with connections to stress-granule-formation, mRNA-stability, splicing-regulation, and stress-response. PKM2 (pyruvate-kinase-muscle-isozyme-2, chromosome-15q23, ~531-amino-acids, glycolytic-enzyme-with-protein-kinase-activity) is the canonical-Warburg-effect-driver in cancer-cells; PKM1-vs-PKM2-splicing-switch (via-hnRNPA1/PTBP1/PSF/SRSF3-splicing-factors) determines-glycolytic-vs-oxidative-phosphorylation-balance.

Why it matters for BB + action — Ingest GSE339058 raw TXT files via the standard bulk-RNA-seq-pipeline (Salmon/kallisto + DESeq2/edgeR + GSEA/GSVA + MSigDB-HALLMARK-GLYCOLYSIS-gene-set + MSigDB-HALLMARK-OXIDATIVE-PHOSPHORYLATION-gene-set + MSigDB-HALLMARK-MYELOMA-signature + PKM-pathway-gene-set [PKM, PKM2, PKM1, HNRNPA1, HNRNPA2B1, PTBP1, SRSF3, CIRBP, RBM3, RBM10] + intron-retention-gene-set-computation [bam-file-intron-retention-quantification-via-IRFinder-or-IntEREst-or-MAJIQ] + macrophage-polarization-markers [ARG1, CD163, MRC1, NOS2, IL12A, IL6, TNF, IL10, TGFB1]), identify-CIRBP-KD-vs-control-MM-cell-DEGs, identify-CIRBP-OE-vs-control-MM-cell-DEGs, identify-PKM2-intron-retention-rate-by-condition (CIRBP-OE-should-INCREASE-intron-retention-rate-of-PKM2-pre-mRNA, reducing-functional-PKM2-protein-level), identify-Warburg-vs-OXPHOS-shift-by-condition (lactate-production + glucose-consumption + OCR/ECAR-ratio), identify-M2-macrophage-polarization-markers-by-CIRBP-status (CIRBP-KD-should-PROMOTE-M2; CIRBP-OE-should-PROMOTE-M1), cross-reference with public-MM-atlases (the Zhan-2002-MM-GEP-cohort + the Mulligan-2007-MM-GEP + the Broyl-2010-MM-7q-gain + the Chapman-2011-MM-WGS-cohort + the Lohr-2014-MM-WES + the Walker-2018-MM-RNA-seq + the Maura-2024-MM-multi-omic-atlas) + public-PKM2-atlases (the Christofk-2008-PKM2-Warburg + the Luo-2011-PKM2-splice-switch + the Israelsen-2013-PKM2-knock-in + the Dayton-2021-PKM2-kinase-activity + the Liu-2024-PKM2-intron-retention-discovery) + public-CIRBP-atlases (the Nishiyama-1997-CIRBP-clone + the Liao-2017-CIRBP-stress + the Zhong-2019-CIRBP-cancer + the Yang-2023-CIRBP-immune + the Liu-2024-CIRBP-tumor-microenvironment) + clinical-trial-data (MM-therapies-IMiDs-lenalidomide-Revlimid-pomalidomide-Pomalyst-FDA-approved + PIs-bortezomib-Velcade-carfilzomib-Kyprolis-ixazomib-Ninlaro-FDA-approved + anti-CD38-daratumumab-Darzalex-FDA-approved-2015-isatuximab-Sarclisa-FDA-approved-2020 + anti-BCMA-ADC-belantamab-mafodotin-Blenrep-FDA-approved-2020-withdrawn-2022 + CAR-T-idecabtagene-vicleucel-ABECMA-FDA-approved-2021 + ciltacabtagene-autoleucel-CARVYKTI-FDA-approved-2022 + bispecific-T-cell-engager-teclistamab-TECVAYLI-FDA-approved-2022 + elranatamab-ELREXFIO-FDA-approved-2023 + talquetamab-TALVEY-FDA-approved-2023 + CIRBP-targeting-no-clinical-yet + PKM2-activator-TEPP-46-preclinical + PKM2-inhibitor-shikonin-preclinical + shikonin-PKM2-anti-MM-preclinical + RBP-targeting-no-clinical-yet + intron-retention-modulator-no-clinical + M2-macrophage-reprogramming-no-clinical + Warburg-metabolism-vulnerability-targeting-no-clinical), and package as a candidate list of (a) CIRBP-target-validation (CIRBP-CSD-domain-blocking-peptide + CIRBP-RNA-binding-domain-blocking-peptide + CIRBP-stress-granule-disruptor); (b) PKM2-splice-switch-modulator (PKM1-promoting-compound + PKM2-intron-retention-promoting-compound); (c) RBP-RNA-binding-domain-blocking-peptide-mimetic-class; (d) intron-retention-as-oncotarget (intronic-splice-site-blocking-PNA + antisense-oligonucleotide-for-intron-retention-induction); (e) MM-Warburg-vulnerability-stratification-biomarker; (f) M2-macrophage-reprogramming-via-CIRBP-modulation; (g) MM-CAR-T-resistance-via-M2-macrophage-stratification; (h) cross-cancer-CIRBP-validation-cohort (pan-cancer-CIRBP-expression + survival-correlation); (i) cold-shock-domain-CSD-drug-discovery-platform. The first deliverable should be a 3-page CIRBP-PKM2-RBP-target-nomination + multiple-myeloma-refractory-cancer + Warburg-vulnerability + M2-macrophage-reprogramming brief, not a clinical-recommendation. Cross-validate with the BB AI-DD + cancer-immunotherapy + longevity-inflammaging service lanes for cross-service opportunity mapping.

### 10. Tracker note — Biotech Infrastructure / §20 silent-failure fix stable for 41+ consecutive days; HF intel probe absent today (no fabricated HF metrics); score-9 ladder fully-recycled again, score-7 + score-6 band delivers 3 fresh NOVEL signals across 3 BB lanes: The 2026-09-20 research-watcher scan returned 103 fresh hits across 27 queries (collected_at 2026-09-19T21:02Z, mtime 2026-09-20 06:02 KST, scan.json keys [mode, axis, generated_at, hit_count, hits, queries, source_errors], zero source_errors, scan.log with `[brown-biotech] watcher done` footer) after the §20 silent-failure fix has now been stable for 41+ consecutive days (per the cron-silent-failure-diagnostics skill §20). Today is a Sunday — the §18 weekend-gap pattern will reduce Saturday/Sunday coverage to the smaller subset, Monday back to full 27-query weekday set. The score-9 top-band is FULLY RECYCLED at accession level — all 12 score-9 accessions appear in the prior id:97-id:101 retention window (regex-extracted 60 GSE accessions from page.tsx for robust multi-day dedupe per the §20-A pitfalls pattern validated 2026-08-27). The actionable NOVEL signals today come from the score-7 and score-6 bands after pdat-filter (≤30 days freshest primary, ≤90 days fallback) + prior-id:97-id:101-dedupe + mammalian-taxon-filter + BB-domain-keyword-filter (stromal-niche / EMT-state / TGFβ1 / Oncostatin-M / OSM / cancer-associated-fibroblast / spatial-transcriptomics / scRNA-seq / ATGL / PNPLA2 / fatty-acid-metabolism / plasma-membrane-cholesterol / phospholipid-remodeling / CIRBP / PKM2 / intron-retention / multiple-myeloma / macrophage-alternative-activation / M2-polarization / RNA-binding-protein / Warburg-effect). The 3 NOVEL signals today span 3 BB lanes: (a) **Bioinformatics & Multi-Omics + Cancer EMT + Two Distinct Stromal Niches + scRNA-seq + Spatial Companion Bundle** — GSE316348 + GSE316768 companion bundle (RNA-Seq + scRNA-seq, score 7/7, n=30 total, pdat 2026/09/17 = 2 days ago, selected as Signal 1), (b) **Longevity + Metabolic Disease + ATGL/PNPLA2 Target Nomination + Plasma-Membrane Cholesterol Homeostasis** — GSE346963 ATGL-dependent-phospholipid-remodeling-membrane-cholesterol atlas (selected as Signal 2, score 6, n=8, pdat 2026/09/18 = 1 day ago), (c) **AI Drug Discovery + Refractory Cancer + Multiple Myeloma + RNA-Binding-Protein Target Nomination + Macrophage Alternative Activation** — GSE339058 CIRBP-PKM2-intron-retention-MM-macrophage-reprogramming atlas (selected as Signal 3, score 6, n=4, pdat 2026/09/18 = 1 day ago). Honorable mentions: GSE347085 [Hepatitis E virus insertions antiviral response, n=12, pdat 2026/09/18], GSE347843 [rice OsPSY8 overexpression — out of BB-domain, plant], GSE316348+GSE316768 [companion bundle — selected as Signal 1], GSE286186 [Single-Nucleus Transcriptomic Atlas of Human Glomerular Diseases, n=59, pdat 2026/09/08], GSE337131 [Spatial transcriptomics of early-grade Huntington's disease Caudate, n=2, pdat 2026/09/01], GSE342738 [Multiscale spatial transcriptomics human amygdala Visium HD, n=5, pdat 2026/08/24], GSE314596 [FAP-Directed Immunotherapy atherosclerosis CITEseq, n=58, pdat 2026/02/02], GSE330687 [PD-L1 metabolic reprogramming NSCLC, n=6, pdat 2026/05/17]. HF intel layer continues to track 9 vendor-intel entries (longevity-db/human-muscle-aging-atlas-snRNAseq + mouse-muscle-aging-atlas-snRNAseq, ProteinGym_v1, OATML-Markslab/ProteinGym_v1, genbio-ai/ProteinGYM-DMS, ICML2022/ProteinGym, Jianwen/protein_ligand_cofolding_posebusters, SharkieJones/celldega_Visium-HD_hCRC).
