Chromatin Level Epigenetic Reprogramming and Altered Transcriptional Dynamics by lncRNAs uc.123 and uc.382 [RNA-seq companion atlas] (GSE344329 + GSE344336, score 4/4, n=10/14, Rattus norvegicus, transcriptomics, pdat 2026/08/24 = 3 days ago, raw files yes, the FRESHEST NOVEL ultra-conserved-lncRNA-uc.123-uc.382 / chromatin-epigenetic-reprogramming / transcriptional-dynamics companion atlas in the entire 2026-08-27 hits.jsonl and a direct longevity + epigenetic-reprogramming + regenerative-medicine input for the BB longevity + bioinformatics lane) ## 📋 Synthesis The 2026-08-27 06:00 KST research-watcher scan completed cleanly via `bash run.sh scan` after the §20 silent-failure fix: 105 fresh hits across 27 queries landed in `research-watcher/output/latest/hits.jsonl` (collected_at 2026-08-26T21:02Z). The score-9 top-band is FULLY RECYCLED at accession level from id:71-id:80 — every score-9 accession today (GSE277080 [spatial-transcriptomics-metrics], GSE328275 [TNBC-CD45+], GSE328422 [lymph-node-metastasis spatio-temporal], GSE337336 [fibroblast-EM microenvironment], GSE306130 + GSE318638 [macrophage-skin-cancer Xenium + Visium pair], GSE311507 [HNF-subtype-vulnerabilities], GSE281462-GSE281465 [non-coding-GWAS-loci 3D-chromatin], GSE334010 [CTHRC1+ lung-fibroblast], GSE331133 [estrogen-vaginal-wall POP], GSE281463, GSE281464) already appears in the prior id:71-id:80 retention window. The score-7 ladder is also RECYCLED (GSE343274 [bleomycin-BAL] from id:77, GSE344363 [carrot-taproot] is plant-biology). The actionable NOVEL signals today therefore come from the score 4-6 band after pdat-filter (≤4 days) + prior-id:71-id:80-dedupe + human/mouse/rat-taxon-filter: (1) **Multiscale spatial transcriptomics resolves the cellular and molecular architecture of the human amygdala** as a 3-dataset multi-platform companion atlas pairing GSE342289 (Xenium spatial, score 6, n=4, Homo sapiens, pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'Xenium atlas') with GSE342709 (Visium HD spatial, score 6, n=51, Homo sapiens, pdat 2026/08/24 = 3 days ago) + GSE342738 (Visium spatial, score 6, n=5, Homo sapiens, pdat 2026/08/24 = 3 days ago — the FRESHEST NOVEL multi-platform human-amygdala spatial-transcriptomic atlas in the entire 2026-08-27 hits.jsonl and the LARGEST-n (n=51 Visium-HD arm) score-6 NOVEL spatial cohort today); (2) **Tumor cell-intrinsic stress states drive sensitivity to CAR T cell-therapy in pancreatic cancer** (GSE319162, watcher score 4, n=13, Mus musculus, metabolism 'Expression profiling by high throughput sequencing', pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'tumor metabolism single-cell' — the FRESHEST NOVEL tumor-cell-intrinsic-stress-state / CAR-T-sensitivity / pancreatic-cancer RNA-seq atlas and a direct refractory-cancer + cell-therapy + biomarker input); (3) **Chromatin Level Epigenetic Reprogramming and Altered Transcriptional Dynamics by lncRNAs uc.123 and uc.382** as a 2-dataset companion atlas pairing GSE344329 (RNA-seq, score 4, n=10, Rattus norvegicus, transcriptomics, pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'OpenFold weights') with GSE344336 (RNA-seq, score 4, n=14, Rattus norvegicus, pdat 2026/08/24 = 3 days ago — the FRESHEST NOVEL ultra-conserved-lncRNA-uc.123-uc.382 / chromatin-epigenetic-reprogramming / transcriptional-dynamics companion atlas in the entire 2026-08-27 hits.jsonl). All three signals are CLEAN NOVEL — absent from id:71-id:80 at both accession and study-family level — and cover three BB lanes: spatial-biology / neuroscience (Signal 1), refractory-cancer / cell-therapy (Signal 2), and longevity / epigenetic-reprogramming (Signal 3). No HuggingFace intel section is included today (the watcher's HF intel probe was not in scope for this scan). Recommended BB next moves: ingest the amygdala companion atlas as the spatial-biology reference for the BB neuroscience + AI-DD lane; characterize the CAR-T-stress-state signatures from GSE319162 for pancreatic-cancer patient-stratification; evaluate uc.123 / uc.382 epigenetic targets for partial-reprogramming + longevity lane. --- ## 🎯 Highlights ### 1. Signal 1 — Spatial Biology + Neuroscience + AI Drug Discovery / Multiscale spatial transcriptomics resolves the cellular and molecular architecture of the human amygdala [Xenium + Visium HD + Visium multi-platform companion atlas]: GSE342289 (watcher score 6, n=4, Homo sapiens, Xenium spatial, pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'Xenium atlas', collected_at 2026-08-26T21:01Z) paired with GSE342709 (watcher score 6, n=51, Homo sapiens, Visium HD spatial, pdat 2026/08/24 = 3 days ago) + GSE342738 (watcher score 6, n=5, Homo sapiens, Visium spatial, pdat 2026/08/24 = 3 days ago) form the FRESHEST NOVEL multi-platform (Xenium single-molecule-resolution + Visium-HD sub-cellular + Visium spot-level) human-amygdala spatial-transcriptomic atlas in the entire 2026-08-27 hits.jsonl and a direct spatial-biology + neuroscience + AI-DD-target-nomination + stress-axis-biomarker input for the BB bioinformatics + longevity lane. The amygdala is the central nucleus of the limbic system and the master regulator of emotion-processing, fear-conditioning, reward, anxiety, stress-axis (HPA-axis) output, and autonomic/endocrine stress responses — it integrates cortical emotion input (medial prefrontal cortex, anterior cingulate, insular cortex), hippocampal context/memory input, thalamic/sensory input, and outputs via the central amygdala (CeA) to the hypothalamus (paraventricular nucleus PVN → CRH release → pituitary ACTH → adrenal cortisol), brainstem (periaqueductal gray for freezing response, locus coeruleus for norepinephrine arousal), and ventral striatum (nucleus accumbens for reward). The amygdala comprises ~13 nuclei in humans: basolateral (BLA, the cortical-input station, glutamatergic pyramidal neurons), central (CeA, the main output station, GABAergic), lateral (LA, the gateway for thalamic sensory input), intercalated cell masses (ITC, GABAergic feedforward inhibition gates that filter fear-memory output), and medial (MeA, olfactory/pheromonal input). The clinical relevance is enormous: amygdala dysfunction is implicated in PTSD (fear-memory hyperconsolidation + impaired extinction), generalized anxiety disorder, panic disorder, depression (especially the amygdala-insula-cingulate 'salience-network' hyperactivation seen on fMRI), addiction (ventral-tegmental-area → nucleus-accumbens → amygdala reward circuit), and Alzheimer's disease (the amygdala is one of the earliest regions to accumulate tau pathology and amyloid deposition, and amygdala atrophy is a strong early-AD biomarker). The Xenium + Visium-HD + Visium multi-platform design is the freshest BB signal: Xenium (10x Genomics single-molecule fluorescence-in-situ-hybridization, ~5,000-plex gene panel at sub-cellular resolution) provides single-cell + sub-cellular spatial gene-expression mapping; Visium HD (10x Genomics, 2-µm bin resolution) provides sub-cellular-resolution spot-level expression across the full transcriptome; Visium (10x Genomics, 55-µm spot resolution) provides whole-transcriptome spot-level expression. Combining the three yields: (a) cell-type-identification via Xenium (e.g., CRH+ CeA neurons, GABAergic ITC cells, BLA pyramidal neurons, parvalbumin+ interneurons, microglia, astrocyte subtypes, oligodendrocyte-lineage cells, vascular-endothelial cells, pericytes), (b) cell-type-specific gene-expression from Visium HD at sub-cellular resolution, and (c) whole-transcriptome quantification from Visium for de-novo gene discovery and pathway analysis. Direct BB lane fits: neuroscience + spatial-biology (the multi-platform spatial atlas is the foundational resource for stress-axis + limbic-system AI-DD target-nomination), biomarker (amygdala-region-specific gene-expression signatures of stress-susceptibility vs stress-resilience for PTSD / depression patient-stratification), AI-DD target-nomination (CRH-receptor antagonists, glucocorticoid-receptor modulators, FKBP5 inhibitors, GABA-A-receptor positive-allosteric modulators, NPY-Y1 agonists, oxytocin-receptor agonists, TACR1/2 antagonists, and CCR2 microglia modulators are the actionable target list). ### 2. Signal 2 — Refractory Cancer + Cell Therapy + AI Drug Discovery / Tumor cell-intrinsic stress states drive sensitivity to CAR T cell-therapy in pancreatic cancer [CAR-T-sensitivity-stratification RNA-seq atlas]: GSE319162 (watcher score 4, n=13, Mus musculus, metabolism 'Expression profiling by high throughput sequencing', pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'tumor metabolism single-cell', collected_at 2026-08-26T21:01Z) is the FRESHEST NOVEL tumor-cell-intrinsic-stress-state / CAR-T-sensitivity / pancreatic-cancer RNA-seq atlas in the entire 2026-08-27 hits.jsonl and a direct refractory-cancer + cell-therapy + biomarker input for the BB clinical + AI-DD lane. Pancreatic ductal adenocarcinoma (PDAC) is the prototypical refractory GI cancer (~64,000 US cases/year, ~50,000 deaths/year, 5-year overall survival ~13%, the worst of all common cancers, mostly diagnosed at metastatic stage when resection is not feasible) and one of the most-CAR-T-resistant solid tumors despite multiple clinical trials targeting MSLN (mesothelin, e.g., CART-meso trials), CEA (CAR-CEA trials), Claudin18.2 (CT041 / zolbetuximab-claudin18.2 CAR-T, the most-recently-approved Claudin18.2-targeted antibody), HER2 (HER2-CAR-T trials), and PSCA (prostate-stem-cell-antigen CAR-T trials). The CAR-T-resistance mechanisms in PDAC are multifactorial: (a) physical barrier — the desmoplastic stroma (rich in cancer-associated-fibroblasts [CAFs], hyaluronan, collagen-I, fibronectin, TGF-β, periostin) limits T-cell trafficking and infiltration, (b) antigen escape — heterogeneous target-antigen expression (MSLN-low/negative cells escape MSLN-CAR-T, etc.), (c) immunosuppressive microenvironment — TGF-β, IL-10, adenosine (CD39/CD73), PD-L1+ myeloid cells, M2-polarized tumor-associated-macrophages, Tregs, myeloid-derived-suppressor-cells (MDSCs), (d) metabolic barrier — hypoxia, low glucose, lactate accumulation, tryptophan depletion (IDO1/TDO2), (e) tumor-cell-intrinsic resistance — MHC-class-I downregulation (β2M/HLA-loss, ~20-40% of PDAC), IFNγ-signaling-resistance (JAK1/JAK2 loss-of-function mutations in ~10-20% of PDAC, makes IFNγ-CAR-T ineffective), and — the freshest BB signal — 'tumor cell-intrinsic stress states' that modulate tumor-cell vulnerability to T-cell killing. Recent single-cell + CRISPR-perturbation work has identified multiple tumor-cell-intrinsic stress-state programs that determine CAR-T-sensitivity: (1) integrated-stress-response (ISR, PERK-ATF4-GADD34) — chronic ISR activation can be either pro-death (if unresolved) or pro-survival (if GADD34-mediated translational recovery occurs); CAR-T efficacy correlates with target-cell eIF2α-phosphorylation levels and ATF4 transcriptional output, (2) ferroptosis-susceptibility state — defined by GPX4-dependence, lipid-peroxidation-tolerance, and ACSL4/SLC7A11 expression balance; ferroptosis-vulnerable PDAC cells are preferentially killed by CAR-T cells because CAR-T-cell-derived IFNγ suppresses SLC7A11/xCT and induces lipid-ROS accumulation in target cells, (3) OXPHOS vs glycolysis dependency — OXPHOS-high tumor cells are more-vulnerable to mitochondrial-stress-induced apoptosis during CAR-T-cell engagement (because IFNγ-induced nitric oxide + superoxide overwhelm OXPHOS capacity), (4) NRF2-active oxidative-stress-response state — NRF2-high PDAC cells are more CAR-T-resistant due to enhanced ROS-detoxification and drug-efflux-pump expression, (5) hypoxia-HIF1α-driven state — chronic HIF1α activation drives metabolic reprogramming toward glycolysis + lactate production + PD-L1 upregulation, all of which suppress CAR-T function. The GSE319162 dataset likely profiles mouse PDAC tumors under CAR-T treatment ± metabolic-stress-modulating drugs (glutamine-antagonism via CB-839 / DRP-104, ferroptosis-induction via IKE / erastin, ISR-modulation via ISRIB / integrated-stress-response-inhibitor) — yielding a stress-state × CAR-T-sensitivity map for patient-stratification. Direct BB lane fits: refractory-cancer (PDAC is BB's prototypical refractory-cancer case), cell-therapy (CAR-T-sensitivity stratification is the actionable clinical readout), biomarker (stress-state gene-expression signatures for pre-treatment CAR-T-responder prediction), AI-DD (CRISPR-perturbation targets that sensitize PDAC to CAR-T — the actionable target list includes GCN2/eIF2α kinases, SLC7A11/xCT, GPX4, NRF2, HIF1α, β2M, JAK1/2, B2M, antigen-presentation-pathway members). ### 3. Signal 3 — Longevity + Epigenetic Reprogramming + Regenerative Medicine / Chromatin Level Epigenetic Reprogramming and Altered Transcriptional Dynamics by lncRNAs uc.123 and uc.382 [ultra-conserved-lncRNA chromatin-reprogramming companion atlas]: GSE344329 (watcher score 4, n=10, Rattus norvegicus, transcriptomics 'Expression profiling by high throughput sequencing', pdat 2026/08/24 = 3 days ago, raw files yes, watcher query 'OpenFold weights', collected_at 2026-08-26T21:01Z) paired with GSE344336 (watcher score 4, n=14, Rattus norvegicus, pdat 2026/08/24 = 3 days ago) form the FRESHEST NOVEL ultra-conserved-lncRNA-uc.123-uc.382 / chromatin-epigenetic-reprogramming / transcriptional-dynamics companion atlas in the entire 2026-08-27 hits.jsonl and a direct longevity + epigenetic-reprogramming + regenerative-medicine input for the BB longevity + bioinformatics lane. Ultra-conserved (uc.) long non-coding RNAs (lncRNAs) are a class of ~200-700nt transcripts with 100% sequence conservation between human, mouse, and rat — significantly higher conservation than protein-coding genes (median conservation ~80%) and far higher than typical lncRNAs (median conservation ~30-40%) — first systematically characterized by the Calin/Croce group via genomic-alignment of transcripts from multiple species (Bejerano et al. 2004 Science; Calin et al. 2007; Scaruffi 2009). The uc-lncRNA family (e.g., uc.123, uc.134, uc.282, uc.339, uc.382, uc.417) is enriched for tissue-specific functions in embryonic development, pluripotency, hematopoiesis, neurodevelopment, and stress-response. uc.339 was the first-characterized uc-lncRNA with oncogenic function (Calin group, mapped to the T-Cell-Lymphoma Invasion and Metastasis 1 [TIAM1] locus, regulates cell-cycle progression). uc.282 was linked to hematopoiesis. uc.123 and uc.382 are less-characterized but the title suggests they regulate 'Chromatin Level Epigenetic Reprogramming and Altered Transcriptional Dynamics' — implying they modulate: (a) chromatin accessibility via recruitment / scaffolding of chromatin-remodeling complexes (SWI/SNF / BAF / PBAF for nucleosome-positioning, PRC2/EZH2-SUZ12-EED for H3K27me3-deposition at target loci, COMPASS/SET1/MLL for H3K4me3-deposition at active promoters, NuRD/CHD3-CHD4-HDAC1-HDAC2 for HDAC-mediated silencing, ATRX/DAXX for H3.3-deposition at telomeric/pericentromeric heterochromatin), (b) histone modifications (H3K4me3 / H3K27ac / H3K9me3 / H3K27me3 / H3K79me2 deposition at target loci via cis-acting recruitment of writers / erasers), (c) DNA methylation (TET1/TET2/TET3-mediated 5-methylcytosine-hydroxylation, DNMT1/DNMT3A/DNMT3B-mediated methylation, UHRF1-mediated maintenance methylation), (d) 3D-genome architecture (TAD-boundary maintenance, CTCF/cohesin-mediated enhancer-promoter looping, A/B-compartment switching). The connection to longevity + partial-reprogramming is the freshest BB signal: epigenetic drift (progressive accumulation of stochastic epigenetic errors across cell-division cycles) is one of the canonical hallmarks of aging (López-Otín 2013/2023) and is quantified by epigenetic clocks (Horvath 2013, Hannum 2013, GrimAge 2019, PhenoAge 2018, DunedinPACE 2023) and epigenetic-age-acceleration measures. Partial-reprogramming approaches — transient OSK (OCT4/SOX2/KLF4 or OSK without c-MYC) expression in vivo or in vitro — can reset epigenetic age without erasing cellular identity (Belmonte lab Lu et al. 2020 Nature Aging; Cohen lab Kerepesi et al. 2023; Ocampo et al. 2016) — and have shown rejuvenation in retinal-ganglion-cells, muscle-stem-cells, hematopoietic-stem-cells, and skin. Identifying uc-lncRNAs that mediate chromatin-level reprogramming (e.g., recruit SWI/SNF to pluripotency loci, evict PRC2 from senescence-effector loci, deposit H3K4me3 at Yamanaka-factor-target sites) opens a new target class for: (a) partial-reprogramming-therapeutics (small-molecule or ASO / siRNA / CRISPRa modulators of uc.123 / uc.382 to reset epigenetic age without full iPSC reprogramming), (b) senescence-reversal (the SASP-suppressor + chromatin-reset combination is uniquely achievable via lncRNA-mediated partial-reprogramming), (c) regenerative-medicine (liver-regeneration, muscle-regeneration, hematopoiesis-restoration in aged HSCs). Direct BB lane fits: longevity (epigenetic-age-reset is BB's prototypical longevity intervention), epigenetic-reprogramming (the mechanistic foundation), regenerative-medicine (the therapeutic application), AI-DD target-nomination (uc.123 / uc.382 small-molecule modulators, antisense-oligonucleotide therapeutics, CRISPRa-activators of beneficial uc-lncRNAs, CRISPRi-repressors of detrimental uc-lncRNAs). ### 4. Tracker note — Biotech Infrastructure / HuggingFace AI-DD + longevity intel scan: Today's research-watcher run (2026-08-27 06:00 KST) returned 105 hits across 27 queries from the GEO-source scan only — the HuggingFace + longevity-db intel probe that fed the prior id:74-id:80 tracker-note sections is not present in today's `scan.json` (the watcher's HF query-fan-out appears to have been disabled or returned no entries for this run). The GEO-source scan is therefore the sole basis for today's 3 NOVEL signals; no HuggingFace entity movement to report. Next scan (2026-08-28) should restore the HF intel probe; if the probe is intentionally disabled (e.g., for a quiet Sunday scan or scheduled maintenance window), this will be reflected in the next scan's `source_errors` field. Recommended BB move: continue to monitor the GEO-source scan for spatial-biology + refractory-cancer + longevity + epigenetic-reprogramming lanes; flag the missing HF intel probe to the watcher maintainer if it persists beyond the next scan. --- ## 💼 Next Steps - **[Open GSE342289 in GEO (human-amygdala Xenium spatial, n=4)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE342289)** - **[Open GSE342709 in GEO (human-amygdala Visium HD spatial, n=51, largest arm)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE342709)** - **[Open GSE342738 in GEO (human-amygdala Visium spatial, n=5)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE342738)** - **[Open GSE319162 in GEO (CAR-T-stress-state PDAC RNA-seq, n=13)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE319162)** - **[Open GSE344329 in GEO (uc.123/uc.382 lncRNA chromatin-reprogramming RNA-seq, n=10)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE344329)** - **[Open GSE344336 in GEO (uc.123/uc.382 lncRNA chromatin-reprogramming RNA-seq, n=14)](https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE344336)** - **[Request amygdala-spatial + CAR-T-PDAC-stress + uc-lncRNA-epigenetic-reprogramming brief](https://brownbio.tech/services/ai-drug-discovery#brief)** --- ## 📡 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:** 2026-08-27 06:06 KST - **Repo:** `ohbryt/brown-biotech-platform` --- _Auto-published by `brown_biotech_research_digest_publisher.py` · [brownbio.tech](https://brownbio.tech) · Decision-ready research, daily._
