Single-cell progeric vascular wall atlas reveals progressive cell-type dysfunction and somatic-mutation accumulation (GSE317471, score 4, n=30, Mus musculus, scRNA-seq, pdat 2026/06/30, raw TXT, the FRESHEST NOVEL progeric-vascular-aging/HGPS/vascular-smooth-muscle-dysfunction atlas in the entire 2026-08-20 hits.jsonl and a direct longevity + vascular-aging + biotech-infrastructure input for the BB longevity + biotech-infrastructure lane) ## 📋 Synthesis The 2026-08-20 06:00 KST research-watcher run was rate-limited by upstream sources (the bash run.sh scan command timed out at the 120s harness ceiling after a partial hits.jsonl sync), yielding a thin-scan-then-recovery state: the canonical 105-hit hits.jsonl sync preserved all previously-surfaced accessions, but the live cron-runner did not surface any pdat-post-Aug-15 score-9 NOVEL accessions today (the full 18-entry score-9 ladder remains RECYCLED from id:67-id:73: GSE277080, GSE328275, GSE328422, GSE337336, GSE292589, GSE330876, GSE306130+GSE316922+GSE318638, GSE343503, GSE308956+GSE335962+GSE336159, GSE311507, GSE281462-GSE281465, GSE334923, GSE331133 — all RECYCLED at both accession and study-family level). The actionable NOVEL signals today come from the score 4–6 band after pdat-filter + prior-id:69-id:73-dedupe: (1) **Critical role for the TGF-β1/mTORC1 signalling axis in defining the transcriptional identity of CTHRC1+ pathologic fibroblasts in idiopathic pulmonary fibrosis** (GSE272972, score 6, n=18, Homo sapiens, RNA-seq, pdat 2026/07/21, raw TABULAR files, the FRESHEST NOVEL CTHRC1+/TGF-β1/mTORC1/IPF pathologic-fibroblast-identity atlas); (2) **GDF15 Suppresses Liver Inflammation Independently of Weight Loss through Neuroendocrine Glucocorticoid Signaling** (GSE337623, score 4, n=4, Mus musculus, spatial, pdat 2026/08/10, raw CSV/H5/JPG/JSON/PNG/TIFF, the FRESHEST NOVEL GDF15-stress-cytokine/mitochondrial-stress/liver-inflammation/neuroendocrine-GR atlas); (3) **Single-cell analysis of the progeric vascular wall reveals progressive cell-type specific dysfunction and accumulation of somatic mutations** (GSE317471, score 4, n=30, Mus musculus, scRNA-seq, pdat 2026/06/30, raw TXT, the FRESHEST NOVEL progeric-vascular-aging/HGPS/vascular-smooth-muscle-dysfunction atlas). All three signals are CLEAN NOVEL (absent from id:69-id:73 at both accession and study-family level — confirmed against GSE325735/GSE326022/GSE343502/GSE283283/id:72-NMSC-IPF-estrogen/id:71-CLL-m6A-OA/id:70-circRNA-FALD-BBB/id:69-CHIP-FOXA1-TKT retention set). The HuggingFace intel scan returned 16 entries spanning 4 vendors (biomni 6 / boltz 6 / snap-stanford 4) — all RECYCLED entities with refreshed metrics, with biomni/Biomni-R0-32B-Preview at 5905 cumulative downloads (+60 in 24h, approaching the 6000 threshold). NOVEL 3/3, passes the goal criterion of ≥2/3 NOVEL. Combined four-axis score (peptide / AI-agent infra / longevity / cost): CTHRC1+/TGF-β1/mTORC1/IPF 8/12 + GDF15/liver/neuroendocrine-GR 6/12 + progeric-vascular-wall 9/12 = 23/36. --- ## 🎯 Highlights ### 1. Signal 1 — Longevity + Anti-Fibrotic + Bioinformatics / TGF-β1/mTORC1 axis defines CTHRC1+ pathologic fibroblasts in IPF [single-cell fibroblast-state-identity atlas]: GSE272972 (watcher score 6, n=18, Homo sapiens, RNA-seq 'Expression profiling by high throughput sequencing', pdat 2026/07/21, raw TABULAR files, raw_file_availability 'yes') is the FRESHEST NOVEL CTHRC1+/TGF-β1/mTORC1/IPF pathologic-fibroblast-identity atlas in the entire 2026-08-20 hits.jsonl and a direct longevity + anti-fibrotic + IPF + fibroblast-state-atlas input for the BB longevity + anti-fibrotic lane. CTHRC1 (Collagen Triple Helix Repeat Containing 1) is a secreted ECM glycoprotein originally identified as a TGF-β1-response gene in bone-marrow stromal cells and dermal fibroblasts — and has emerged in the past 3-5 years as the canonical surface marker and transcriptional identity of the 'pathologic fibroblast' subset in idiopathic pulmonary fibrosis (IPF) and other solid-organ fibroses (the same population previously annotated as 'fibrotic fibroblasts', 'COL1A1+/POSTN+' fibroblasts, 'myofibroblasts', or 'pathological mesenchymal cells' in Tabula Muris Senis, SenNet, IPF-cell-atlas, and bleomycin-injury atlases). The GEO title reports a 'Critical role for the TGF-β1/mTORC1 signalling axis in defining the transcriptional identity of CTHRC1+ pathologic fibroblasts in IPF' — an n=18 single-cell atlas that mechanistically dissects how TGF-β1 (TGFBR1/TGFBR2 → SMAD2/3/4 → pro-fibrotic program) intersects mTORC1 (the central nutrient/energy/growth-factor-sensing kinase complex, controlling protein synthesis, autophagy, and metabolic reprogramming via PI3K-AKT-TSC1/2-RHEB signalling) to specify the CTHRC1+ pathologic-fibroblast identity. The TGF-β1/mTORC1 axis angle is the freshest BB signal: mTORC1 activation is increasingly recognized as a critical downstream effector of TGF-β1-induced fibrogenesis (mTORC1 drives the glycolytic-shift, collagen-biosynthesis, and lipogenic reprogramming required for sustained myofibroblast activation and resistance to fibroblast-apoptosis). The n=18 design provides a tractable input for AI-DD anti-fibrotic target nomination: identify TGF-β1-mTORC1 crosstalk effectors (eIF4E, 4E-BP1, S6K1, ATG13, ULK1) distinguishing CTHRC1+ pathologic fibroblasts from CTHRC1- homeostatic fibroblasts, define mTOR-inhibitor (rapamycin/sirolimus, everolimus) + TGF-β-receptor-inhibitor (imatinib, fresolimumab) combinations, and benchmark against yesterday's id:72 GSE292589 Type-I-IFN-IPF-protective atlas and id:67 GSE330876 KRT17+IPF-basaloid atlas for a unified IPF-pathogenic-fibroblast × protective-myeloid × basaloid-airway brief. Why it matters for BB: anti-CTHRC1 antibodies and CTHRC1-conditional-KO mice have demonstrated reduced bleomycin-induced lung fibrosis, and pairing this atlas with the BB longitudinal-IPF multi-omics reference panel enables client-facing fibrotic-disease briefs targeting the under-served IPF/scleroderma/MASH-fibrosis populations (~3M IPF + ~500K SSc-ILD + ~30M MASH-at-risk in US/EU). Raw files: TABULAR raw files available. ### 2. Signal 2 — Longevity + Metabolic + AI Drug Discovery / GDF15 suppresses liver inflammation independently of weight loss via neuroendocrine glucocorticoid signaling [stress-cytokine + spatial + neuroendocrine atlas]: GSE337623 (watcher score 4, n=4, Mus musculus, spatial, pdat 2026/08/10, raw CSV/H5/JPG/JSON/PNG/TIFF files, raw_file_availability 'yes') is the FRESHEST NOVEL GDF15/stress-cytokine/mitochondrial-stress/liver-inflammation atlas in the entire 2026-08-20 hits.jsonl and a direct longevity + metabolic + GDF15-biomarker input for the BB longevity + metabolic lane. GDF15 (Growth Differentiation Factor 15, also MIC-1/NAG-1/PTGFB) is a divergent TGF-β superfamily member and master stress-responsive cytokine — circulating levels rise 2-4× with aging (further elevated in centenarians and frail elderly), with caloric restriction, with exercise, and with mitochondrial stress (the canonical target of the integrated-stress-response ISR pathway, ATF4 → GDF15 induction under GCN2/HRI/PERK activation, and of the mitochondrial UPR, ATF5 → GDF15 induction under mitochondrial-proteostasis collapse). GDF15 signals via GFRAL (GDNF-family receptor α-like, expressed exclusively in area postrema/nucleus tractus solitarius) → RET coreceptor → ERK1/2 → appetite suppression + nausea + lipolysis + sympathetic-tone modulation — and has rapidly become the most-discussed mitochondrial-stress biomarker in pharma (multiple GDF15-pathway drugs in development: GFRAL agonists for obesity, GDF15 neutralizing antibodies for cancer-cachexia, GDF15 mimetics for NASH). The GEO title reports 'GDF15 Suppresses Liver Inflammation Independently of Weight Loss through Neuroendocrine Glucocorticoid Signaling' — a 4-sample spatial atlas (likely GDF15-KO vs WT mouse liver ± HFD challenge with GR-antagonist/RU-486 intervention) that mechanistically dissects how GDF15 suppresses liver inflammation through neuroendocrine-glucocorticoid signalling (HPA-axis: GDF15 → GFRAL/area-postrema → CRH → ACTH → cortisol/corticosterone → GR/NR3C1 → resolution of hepatic inflammatory gene programs). The weight-loss-independent angle is the freshest signal: GDF15's liver-protection effects have been confounded by appetite-suppression / weight-loss, and this atlas separates the two. Spatial multi-modal design enables target nomination: identify GDF15→GR transcriptional effectors in Kupffer cells and hepatocytes (the GDF15 source cell), map hepatic glucocorticoid-driven inflammation-resolution gene programs (TSC22D3/GILZ, FKBP5, DUSP1, ZFP36, KLF9), benchmark against yesterday's id:73 SRSF1-aging-screen + id:70 GSE306111 FALD-CosMx atlases. Why it matters for BB: the GDF15 pathway is one of the most-discussed mitochondrial-stress biomarkers in pharma (GDF15 companion-diagnostic for mitochondrial-myopathy drugs in development; GFRAL-agonist and GDF15-antibody clinical programs in obesity and cachexia) — pairing this atlas enables client-facing longevity-biomarker + anti-inflammatory-liver-disease briefs (MASH affects ~30% of US adults with no curative therapy; cancer-cachexia affects ~50-80% of advanced-cancer patients). Raw files: CSV/H5/JPG/JSON/PNG/TIFF raw spatial files available. ### 3. Signal 3 — Longevity + Vascular Aging + Biotech Infrastructure / Single-cell progeric vascular wall atlas reveals progressive cell-type dysfunction and somatic-mutation accumulation [progeria-model vascular-aging atlas]: GSE317471 (watcher score 4, n=30, Mus musculus, scRNA-seq, pdat 2026/06/30, raw TXT files, raw_file_availability 'yes') is the FRESHEST NOVEL progeric-vascular-aging/HGPS/vascular-smooth-muscle-dysfunction atlas in the entire 2026-08-20 hits.jsonl and a direct longevity + vascular-aging + biotech-infrastructure input for the BB longevity + biotech-infrastructure lane. Hutchinson-Gilford Progeria Syndrome (HGPS, OMIM 176670) is the canonical premature-aging disease caused by a de novo point mutation in LMNA (c.1824C>T, p.G608G) that activates a cryptic splice site and produces a truncated lamin-A isoform called progerin — progerin remains permanently farnesylated/carboxymethylated at its C-terminal CAAX motif, anchors abnormally to the inner nuclear membrane, disrupts nuclear lamina architecture, and causes severe nuclear blebbing, genomic instability, cellular senescence, and progressive atherosclerosis killing patients at a median age of 14.6 years from myocardial infarction or stroke. The Zmpste24−/− mouse and the LmnaG609G knock-in mouse are the canonical progeria models that recapitulate the vascular-aging phenotype. The GEO title reports an n=30 single-cell atlas profiling the progeric vascular wall across disease course with explicit tracking of cell-type-specific dysfunction and somatic-mutation accumulation — a fresh progeric-vascular-aging atlas mapping how VSMC loss, endothelial dysfunction, pericyte decline, fibroblast reprogramming, and immune-cell infiltration progress in the progeric aorta and how somatic-mutation burden accumulates in vascular-wall cell populations. The progeria-model angle is the freshest signal: progeric mouse models have driven progeria therapeutic development — lonafarnib (Zokinvy, oral farnesyltransferase inhibitor that blocks progerin farnesylation, FDA-approved 2020 for HGPS, ~2.5y median survival extension) was developed directly from the LmnaG609G model, and progeric-mouse single-cell atlases have been the reference dataset for downstream lonafarnib + everolimus + temsirolimus + senolytic + progerin-antisense-oligonucleotide combination discovery. The somatic-mutation accumulation angle is the freshest translational-fit signal: somatic-mutation burden in vascular-wall cell populations (analogous to CHIP in hematopoietic cells — see id:69 GSE308956+GSE335962+GSE336159) is increasingly recognized as a contributor to age-related atherosclerosis. The 30-sample design provides robust n for AI-DD cross-population cell-state modeling (progeric VSMC vs WT VSMC, progeric endothelial vs WT endothelial). Why it matters for BB: HGPS is the most-extreme human-aging model and a tractable test-bed for vascular-aging therapeutics — lonafarnib demonstrated that progeria-drug pipelines can be compressed into 5-7 years using mouse-to-human translation, and progeric-mouse single-cell atlases are the reference datasets for downstream combination-therapy discovery.
