the n=28 mouse-kidney MRSA time-course design enables direct innate-immune + adaptive-immune + stromal-response trajectory mapping across the infection course (early neutrophil infiltration, macrophage polarization shift, T-cell recruitment, bacterial-clearance dynamics, tissue-repair trajectory), with the renal focus providing a clean window into disseminated-staphylococcal-infection host response (kidney is a high-burden secondary target in bacteremic S. aureus infection and MRSA-induced acute kidney injury [AKI] is a major driver of mortality in severe sepsis); the n=28 cohort with suppfile TXT format supports standard DEG + pathway-enrichment + immune-cell-deconvolution reanalysis; MRSA-host-response dissection is a direct input for Brown Biotech's infectious-disease + host-directed-therapy + antibiotic-repurposing lane, where CMap-style host-response-signature matching can identify FDA-approved drugs that mimic the transcriptomic signature of effective MRSA clearance (e.g., adjunctive immunomodulators that boost host defense without driving resistance); the score-6 ranking (highest among today's fresh unduplicated picks) reflects the high-priority-pathogen + clean-license + raw-files-available + time-course design combination; first promoted to primary feature today; pairs with the GSE302227 MRSA-kidney Multiome (score 4, pdat 2026/07/04, n=8, paired multiome ATAC+RNA on the same MRSA-kidney-injury model, today's combined-signal) on shared MRSA-host-response biology with paired transcriptomic + epigenomic resolution. --- ## 🎯 Highlights ### 1. Mouse kidney Methicillin-resistant Staphylococcus aureus infection time course (GSE302226, score 6, n=28, pdat 2026/07/04, transcriptomics, Mus musculus, clean license, raw files available, suppfile TXT): a freshly deposited (pdat = 3 days ago, the freshest score-6 entry in the current scan) score-6 transcriptomic time course of mouse-kidney MRSA infection, the highest-scored fresh unduplicated hit in the 2026-07-05 scan after rotation past id:25–id:34's 11 already-featured score-4+ entries — the cleanest available input for renal-tropism + time-resolved host-response dissection in methicillin-resistant Staphylococcus aureus (MRSA, a WHO Priority-1 antimicrobial-resistance pathogen and the leading cause of community- and hospital-acquired bacterial infections globally, with >100,000 attributable deaths/year in the US alone and rising vancomycin + daptomycin + linezolid resistance rates driving urgent need for adjunctive host-directed therapies); the n=28 mouse-kidney MRSA time-course design enables direct innate-immune + adaptive-immune + stromal-response trajectory mapping across the infection course (early neutrophil infiltration driven by S. aureus-derived chemotactic peptides [fMLP, PSMα], macrophage polarization shift from M1-like pro-inflammatory to M2-like tissue-repair phenotype, T-cell recruitment dynamics, bacterial-clearance kinetics, and tissue-repair trajectory including fibrotic-remodeling risk); the renal focus provides a clean window into disseminated-staphylococcal-infection host response (kidney is a high-burden secondary target in bacteremic S. aureus infection, with MRSA-induced acute kidney injury [AKI] a major driver of mortality in severe sepsis and Staphylococcus-aureus bacteremia [SAB]); the suppfile TXT format supports standard DEG + pathway-enrichment (GO/KEGG/Reactome/Hallmark) + immune-cell-deconvolution (CIBERSORTx/MCPcounter/xCell) reanalysis; MRSA-host-response dissection is a direct input for Brown Biotech's infectious-disease + host-directed-therapy + antibiotic-repurposing lane, where CMap-style host-response-signature matching can identify FDA-approved drugs that mimic the transcriptomic signature of effective MRSA clearance (e.g., adjunctive immunomodulators that boost host defense without driving further resistance — a key strategy given the dry antibiotic-development pipeline); the score-6 ranking reflects the high-priority-pathogen + clean-license + raw-files-available + time-course design combination; first promoted to primary feature today; pairs with the GSE302227 MRSA-kidney Multiome (score 4, pdat 2026/07/04, n=8, paired multiome ATAC+RNA on the same MRSA-kidney-injury model — today's combined-signal pick) on shared MRSA-host-response biology with paired transcriptomic + epigenomic resolution, and with the GSE337004 PM2.5-induced-mammary-spheroid RNA-seq (score 4, pdat 2026/07/04, n=8, environmental-exposure + breast-cancer-spheroid model — also combined-signal) on shared environmental-exposure + epithelial-stress-response biology. ### 2. Truncated Gpr114-based ultrasound-hypersensitive gene circuit for controlled expression of therapeutics (GSE311869, score 4, n=3, pdat 2026/07/03, protein-design [misclassified — actually synthetic-biology + sonogenetics], Mus musculus, clean license, raw files available, suppfile MTX/TSV): a freshly deposited (pdat = 4 days ago) score-4 synthetic-biology / sonogenetics / acoustogenetics dataset describing a truncated Gpr114-based ultrasound-hypersensitive gene circuit for controlled expression of therapeutics — the cleanest available input for ultrasound-controlled therapeutic-gene-expression circuits in the current scan; Gpr114 (also known as ADGRG5, an adhesion G-protein-coupled receptor from the GPCR family) is a mechanosensitive receptor that responds to mechanical stimuli, and the truncation strategy (typically removing the extracellular N-terminal fragment that keeps the receptor in an autoinhibited state, similar to the canonical Notch / NTF-displacement / Stachel-peptide activation mechanism shared across adhesion GPCRs) creates a gain-of-function mechanosensitive variant that can be activated by focused-ultrasound (FUS) stimulation; the gene-circuit design links Gpr114-truncation activation to a downstream therapeutic-expression cassette (e.g., insulin, anti-TNF nanobody, anti-PD-L1 scFv, IL-10, GLP-1) under synthetic-promoter control, enabling non-invasive, spatially-targeted, on-demand therapeutic-protein expression in vivo; focused ultrasound (FUS) is a clinically-deployed non-invasive stimulation modality (already FDA-cleared for essential tremor, tremor-dominant Parkinson's disease, and bone metastases pain palliation via Insightec Exablate, and in active clinical trials for blood-brain-barrier opening in glioblastoma + Alzheimer's + brain-tumor drug delivery), and pairing FUS with a mechanosensitive-GPCR-based gene circuit enables a closed-loop, non-invasive, drug-like-control therapeutic-platform with no requirement for exogenous small-molecule inducers; the n=3 single-cell cohort (suppfile MTX/TSV) supports cell-type-resolved analysis of which cell populations express the circuit and respond to ultrasound stimulation; this is a direct biotech-infrastructure / synthetic-biology input for Brown Biotech's cell-therapy + gene-therapy dosing-control lane, where on-demand, spatially-controlled expression addresses the canonical safety + dosing + tumor-targeting challenges of in-vivo gene therapy (CAR-T + regulatory-T-cell + Treg + cytokine + antibody-expression circuits); first promoted to primary feature today; the sonogenetics paradigm complements the more-mature optogenetics paradigm (channelrhodopsins + archaerhodopsins + halorhodopsins, widely used in neuroscience but limited by poor tissue-penetration of visible light) with the superior tissue-penetration of ultrasound (cm-scale penetration, including through the skull with FUS), and the truncated-Gpr114 design is the cleanest available non-optogenetic, non-magnetogenetic (Ferritin-based) actuator for in-vivo therapeutic-control applications; pairs with the longevity-db/human-muscle-aging-atlas-snRNAseq (id:31) on shared open-license dataset accessibility and with the broader boltz + biomni vendor-intel channel (today's combined-signal) on shared biotech-infrastructure + AI-driven-design methodology. ### 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, pdat 2026/06/30, single-cell, Mus musculus, clean license, raw files available, suppfile TXT): a freshly deposited (pdat = 7 days ago) score-4 single-cell atlas of the progeric vascular wall revealing progressive cell-type-specific dysfunction + accumulation of somatic mutations — the cleanest available input for progeria + vascular-aging + somatic-mutation-accumulation dissection in the current scan; Hutchinson-Gilford progeria syndrome (HGPS) is the canonical accelerated-aging paradigm, caused by a de novo point mutation in LMNA (c.1824C>T, p.G608G) that creates a cryptic splice site and produces a truncated lamin-A isoform called progerin (a farnesylated + permanently-membrane-associated intermediate that disrupts nuclear-envelope integrity, drives genomic instability, and accelerates cellular aging); HGPS patients display premature cardiovascular pathology (severe atherosclerosis, vascular smooth muscle cell loss, endothelial dysfunction, myocardial infarction, stroke) with median life expectancy of ~14.5 years, almost all dying of cardiovascular causes; the most-common mouse models include LmnaG609G (the knock-in equivalent of the human LMNA c.1824C>T mutation, on a C57BL/6 background) and Zmpste24-deficient mice (ZMPSTE24 is the metalloprotease that cleaves the farnesylated C-terminal tail of pre-lamin-A to mature lamin-A, and Zmpste24-/- mice accumulate farnesylated pre-lamin-A that phenocopies HGPS); the n=30 single-cell cohort enables direct dissection of vascular-wall cell-type-specific dysfunction across the major vascular-wall populations (vascular smooth muscle cells [VSMCs, the contractile cells that lose density in HGPS vascular pathology, driving aneurysm + stenosis], endothelial cells [ECs, with endothelial-to-mesenchymal-transition [EndMT] driving intimal fibrosis], vascular fibroblasts [the stromal source of collagen + fibrotic-remodeling], pericytes + vascular stem cells), and the somatic-mutation-accumulation axis is the molecular-aging signature that drives the premature cardiovascular pathology (with elevated single-nucleotide-variant + small-insertion-deletion burden, characteristic C>T transitions at CpG sites, and clonal hematopoiesis-driver-mutation [CHIP]-like signatures in the vascular-wall populations); this is a direct longevity / progeria + vascular-aging + senolytic-target-nomination input for Brown Biotech's vascular-aging + progeria lane, where the progerin-axis is a tractable therapeutic target (lonafarnib, an FTI [farnesyltransferase inhibitor], received FDA approval in 2020 for HGPS and is the only approved progeria-specific therapy, but combinations with senolytics + autophagy-inducers + progerin-clearance approaches are active translational lanes); the n=30 single-cell cohort with suppfile TXT format supports standard scRNA-seq reanalysis + cell-type-stratified mutation-burden quantification (via single-cell-mutation-calling from read-level data using tools like CellSNP-lite + SCAN-SNV + SComatic); first promoted to primary feature today; pairs with the GSE330351 ferritin cardio-fibrosis atlas (id:30) on shared vascular-cardio-fibrosis biology, and with the longevity-db/human-muscle-aging-atlas-snRNAseq (id:31) on shared aging-biology + single-nucleus-resolved atlas methodology. ### 4. Combined signal: bioinformatics / infectious-disease + host-pathogen + antimicrobial-resistance (Mouse kidney MRSA infection time course, GSE302226, n=28 transcriptomic time course, pdat 3 days ago, the freshest score-6 MRSA-host-response dataset this cycle, the highest-scored fresh unduplicated entry in the 2026-07-05 scan after rotation past id:25–id:34's 11 already-featured score-4+ items) + biotech-infrastructure / synthetic-biology + sonogenetics + ultrasound-controlled gene circuits (Truncated Gpr114-based ultrasound-hypersensitive gene circuit, GSE311869, n=3 single-cell, pdat 4 days ago, the freshest sonogenetic / acoustogenetic / ultrasound-controlled-therapeutic-expression dataset in the current scan, the cleanest available non-optogenetic + non-magnetogenetic in-vivo therapeutic-control actuator and a direct enabling technology for cell-therapy + gene-therapy dosing control) + longevity / progeria + vascular-aging + somatic-mutation accumulation (Single-cell progeric vascular wall, GSE317471, n=30 single-cell, pdat 7 days ago, the cleanest available input for HGPS + vascular-aging + cell-type-specific dysfunction + somatic-mutation-accumulation dissection in the current scan, a direct senolytic-target-nomination + progeria-therapeutic input for Brown Biotech's longevity lane) + clinical / epigenetics + chromatin + melanoma (GSE301779, n=24 Mus musculus CUT&Run ChIP-seq, pdat 2026/07/04, score-4 'Examine the epigenetic consequences of KMT2D loss in melanoma using ChIP-seq profiling [CUT&Run]' — KMT2D [also known as MLL4, the canonical H3K4 monomethyltransferase writer that installs H3K4me1 at enhancers and super-enhancers] loss-of-function in melanoma, the cleanest CUT&Run dissection of enhancer-epigenome rewiring downstream of KMT2D loss in melanoma, a direct clinical + epigenetics input for KMT2D-mutant-melanoma enhancer-targeted-therapy nomination; pairs with the GSE336618 CosMx-SMI recombinant-HA-vaccine spatiotemporal atlas (also fresh, score 4, pdat 2026/06/25, n=26, vaccine-immunology + CosMx-spatial methodology) on shared chromatin + immune-cell + melanoma + vaccine-spatial methodology threads) + biotech-infrastructure / agentic-bio-AI vendor-intel (the watcher's 2026-07-07 re-scan of the arxiv channels surfaced two biotech-relevant agentic-bio-AI papers: 'Deterministic access to global viral sequence data enables robust agentic scientific discovery' [arxiv 2606.06749, ts 2026-06-04, vendor=phylo] — a paper on deterministic-access viral-sequence-data infrastructure for agentic-bio-AI, the cleanest available data-access-layer architecture for AI-driven viral-genomics + pandemic-preparedness + biosecurity, and 'BioVeil MATRIX: Uncovering and categorizing vulnerabilities of agentic biological AI scientists' [arxiv 2605.00927, ts 2026-04-30, vendor=phylo] — a paper on red-teaming + vulnerability-categorization for agentic-bio-AI systems, the cleanest available input for biosafety + dual-use-risk assessment of agentic-AI-scientist platforms) — five orthogonal modalities spanning 5 of 6 Brown Biotech coverage categories (bioinformatics + clinical + longevity + biotech-infrastructure + ai-drug-discovery); today's three primary picks are the highest-priority + freshest-deposited unduplicated entries (GSE302226 score 6 + GSE311869 score 4 + GSE317471 score 4, all pdat within 7 days) and the two combined-signal items (GSE301779 KMT2D/melanoma CUT&Run + agentic-bio-AI vendor-intel) are bundled as today's supporting signals; the watcher's 2026-07-07 re-scan (collected_at 2026-07-05T21:02–21:03 UTC, the underlying hits.jsonl + intel.jsonl were last updated 2026-07-05 and the 2026-07-07 cron run did not produce a new hits.jsonl in 2026-07-07/ — only an intel/scan.jsonl re-run that surfaced the same 20 arxiv items already in latest/intel.jsonl) ran on its normal 06:00 KST cadence; today's rotation is a clean post-id:25–id:34 mid-cycle pass with 11 of 16 score-4+ entries already featured, leaving MRSA-host-response + sonogenetic-gene-circuit + progeric-vascular-wall as today's three cleanest picks across the bioinformatics + biotech-infrastructure + longevity lanes. --- ## 💼 Next Steps - **[Request bioinformatics / MRSA host-response brief](https://brownbio.tech/multiomics#brief)** - **[Request biotech infrastructure / sonogenetic gene-circuit brief](https://brownbio.tech/services/ai-drug-discovery#brief)** - **[Request longevity / progeric-vascular senolytic-target brief](https://brownbio.tech/services/biostatx#brief)** - **[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:** 2026-07-07 06:08 KST - **Repo:** `ohbryt/brown-biotech-platform` --- _Auto-published by `brown_biotech_research_digest_publisher.py` · [brownbio.tech](https://brownbio.tech) · Decision-ready research, daily._
