[Longevity & Anti-Fibrotic] A macrophage-associated senescence signature emerges from a MASH/fibrosis single-cell atlas (GSE300744, score 4, n=3, Mus musculus, pdat 2026/06/18 = 75 days ago, raw files yes ### 2. linked PMID 42650820 / DOI 10.3390/biom16081154) ### 3. [Clinical & Spatial Oncology] CCL21+ lymphatic endothelial cells coordinate a favorable immune environment in acral melanoma (GSE344166, score 6, n=116, Homo sapiens, pdat 2026/08/24 = 8 days ago, integrated scRNA-seq + spatial transcriptomics + multiplexed immunofluorescence) ### 4. [AI-DD & Longevity] ABCA1-driven cholesterol overload links mitochondrial quality-control failure to neuronal injury (GSE303508, score 6, n=6, Homo sapiens, pdat 2026/08/27 = 5 days ago, single-cell transcriptome ### 5. no linked PMID or DOI listed in the GEO record) ## 📋 Synthesis The 2026-09-01 06:00 KST research-watcher scan completed via the fixed `bash run.sh scan` entry point: 106 hits across 27 queries, scan.json reports hit_count=106 and source_errors=[], and hits.jsonl was written at 2026-09-01 06:03 KST. The three featured accessions are clean NOVEL relative to all GSE references in the retained five-entry page and are absent from yesterday's top five digest entries. The high-score ladder was mostly recycled, so the selection moved to fresh score-4/6 candidates with human or mammalian evidence, a concrete BB lane, and a direct action.\n\nSignal 1 — Longevity & Bioinformatics: GSE300744 is a mouse liver single-cell atlas from HFD-induced MASH and CCl4-induced fibrosis. The linked PubMed study (PMID 42650820; DOI 10.3390/biom16081154) integrated four transcriptomic datasets (127 controls and 127 MASLD cases), used WGCNA, CIBERSORT, and three machine-learning algorithms, then used single-cell analysis of GSE300744 to localize a reduced SOCS1/SOCS2/GADD45G macrophage-associated senescence signature. In the reported experiments, GADD45G fell in HFD mouse liver and palmitic-acid-stimulated macrophages, while camptothecin and myristicin partially restored expression in vitro. Treat these compounds as mechanistic leads, not clinical efficacy.\n\nSignal 2 — Clinical & Spatial Oncology: GSE344166 is a 116-sample human acral-melanoma atlas integrating scRNA-seq, spatial transcriptomics, and multiplexed immunofluorescence. The GEO record identifies CCL21+ IGF1+ IL7+ PDPN+ lymphatic endothelial cells that communicate with dendritic and CD4+ T cells through CCL21-CCR7, with CCL21/CCR7 expression associated with improved survival in melanoma cohorts. The actionable BB use is a spatial immune-niche and response-biomarker map, not a therapy claim; the record does not list a linked PMID or DOI.\n\nSignal 3 — AI Drug Discovery & Longevity: The GEO record for GSE303508 supplies a detailed record-level abstract connecting astrocytic ABCA1 activity, lysosomal cholesterol accumulation, GPR155, mTOR-mediated autophagy suppression, alpha-synuclein aggregation, and neuronal injury. It also reports docking and mouse survival work around magnesium citrate as an ABCA1 inhibitor. The n=6 human cell-line dataset is a prioritization signal, not independent clinical proof, and the record has no linked PMID or DOI.\n\nFour-axis scorecard (peptide / AI-agent infrastructure / longevity / cost; cost is 5 for low ingest burden): GSE300744 = 0/5 / 4/5 / 5/5 / 4/5; GSE344166 = 0/5 / 2/5 / 1/5 / 4/5; GSE303508 = 0/5 / 3/5 / 4/5 / 3/5. The peptide axis is intentionally zero because none of these records is peptide-specific. The infrastructure tracker is GEO-only: today's scan.json has no hf_intel key, and no HuggingFace movement is inferred from the rolling intel.jsonl file. --- ## 🎯 Highlights ### 1. NOVEL + provenance — Signal 1 / Longevity & Bioinformatics: GSE300744 (watcher score 4, n=3, Mus musculus, scRNA-seq, pdat 2026/06/18, raw files yes; query MASH liver atlas) is absent from the retained page and yesterday's top five. The record's single-cell liver resource is the MASH/fibrosis layer used in the linked analysis, while the paper's larger 127-control/127-MASLD discovery cohort supplies orthogonal evidence. ### 2. Evidence — The linked PMID 42650820 study (DOI 10.3390/biom16081154) reports reduced SOCS1, SOCS2, and GADD45G in MASLD liver, macrophage-associated single-cell expression, and partial GADD45G restoration by camptothecin or myristicin in a macrophage assay. This supports a senescence–immune signature for fibrosis-to-HCC monitoring, not an approved-drug claim. ### 3. Four-axis score — peptide 0/5; AI-agent infrastructure 4/5; longevity 5/5; cost 4/5. WGCNA, CIBERSORT, machine-learning feature selection, and single-cell triangulation are the AI-DD layer; the small GEO arm and existing external cohort keep the ingest burden moderate. ### 4. Why it matters for BB + action — Run QC, macrophage-state stratification, and expression-direction validation against a Brown Biotech fibrosis or liver dataset, then package GADD45G/SOCS1/SOCS2 as candidate biomarkers and pathway-response readouts. The first deliverable should be a cross-disease liver-fibrosis/HCC brief, not a compound recommendation. ### 5. NOVEL + provenance — Signal 2 / Clinical & Spatial Oncology: GSE344166 (score 6, n=116, Homo sapiens, pdat 2026/08/24, raw files yes; integrated single-cell + spatial + multiplexed immunofluorescence) is absent from the retained page and yesterday's top five. The large human cohort makes it the strongest spatial-immune prioritization candidate in today's scan. ### 6. Mechanism — The GEO record identifies distinct invasive-front, intratumoral, and distant-inflammation habitats. CCL21+ IGF1+ IL7+ PDPN+ lymphatic endothelial cells signal through CCL21-CCR7 to dendritic and CD4+ T cells, whereas vascular endothelial cells are predicted to interact with fibroblasts and macrophages; CCL21/CCR7 expression is associated with survival. ### 7. Four-axis score — peptide 0/5; AI-agent infrastructure 2/5; longevity 1/5; cost 4/5. The AI-DD value is in cell-cell communication, spatial deconvolution, and response-biomarker modeling rather than an autonomous agent or peptide program; 116 samples make the first pass relatively low cost. ### 8. Why it matters for BB + action — Build a spatial immune-niche map and test whether CCL21/CCR7 predicts immunotherapy response or immune-cell entry in rare/refractory melanoma cohorts. Validate the signal with independent cohorts before using it as a clinical biomarker; no linked PMID or DOI is listed in the GEO record. ### 9. NOVEL + provenance — Signal 3 / AI-DD & Longevity: GSE303508 (score 6, n=6, Homo sapiens, single-cell transcriptome, pdat 2026/08/27, raw files yes) is absent from the retained page and yesterday's top five. The GEO record is the provenance for a mechanistic cholesterol/ABCA1 signal, so its small n and human-cell-line status remain explicit. ### 10. Mechanism — The record-level abstract describes ABCA1-associated astrocyte and dopaminergic-neuron cholesterol dysregulation, lysosomal cholesterol accumulation, GPR155 activation, mTOR-mediated autophagy suppression, alpha-synuclein aggregation, and neurodegeneration. It reports magnesium-citrate docking and mouse survival work; this is a target/repurposing lead, not a clinical result. ### 11. Four-axis score — peptide 0/5; AI-agent infrastructure 3/5; longevity 4/5; cost 3/5. Docking and pathway-level prioritization support AI-DD use, but the six-sample dataset needs independent expression and perturbation confirmation; the cost score reflects that extra validation step. ### 12. Why it matters for BB + action — Add ABCA1-GPR155-mTOR-autophagy to the Brown Biotech neurodegeneration/longevity target map, then run QC and orthogonal validation against mitochondrial-quality-control and alpha-synuclein models. Do not attach an unrelated PMID/DOI; the GEO record has none linked. ### 13. Infrastructure tracker — Today's scan.json contains 106 GEO hits, 27 queries, and zero source_errors, but no hf_intel key. The rolling intel.jsonl feed is not treated as a same-day HuggingFace result, so this digest reports GEO-only evidence without fabricated vendor metrics. --- ## 💼 Next Steps - **[Open GSE300744 in GEO (MASH/fibrosis liver scRNA-seq)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE300744)** - **[Read PMID 42650820 / DOI 10.3390/biom16081154](https://doi.org/10.3390/biom16081154)** - **[Open GSE344166 in GEO (acral-melanoma spatial atlas)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE344166)** - **[Open GSE303508 in GEO (ABCA1/cholesterol transcriptome)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE303508)** - **[Request MASH–senescence + melanoma immune-niche + ABCA1 brief](https://brownbio.tech/services/ai-drug-discovery#brief)** - **[View multiomics service](https://brownbio.tech/services/multiomics)** - **[View biostatx service](https://brownbio.tech/services/biostatx)** --- ## 📡 Provenance - **Source:** research-watcher (PubMed/GEO scan, 27 query families × Brown Biotech pipelines) - **Pipeline:** [`brown-biotech-daily-tech-digest`](https://github.com/ohbryt/brown-biotech-platform) — 06:00 KST cron - **Generated:** 2026-09-01 06:18 KST - **Repo:** `ohbryt/brown-biotech-platform` --- _Auto-published by `brown_biotech_research_digest_publisher.py` · [brownbio.tech](https://brownbio.tech) · Decision-ready research, daily._
