Perception of environmental stressors like food scarcity often leads to physiological changes that promote survival and slow aging. However, recent work shows that perception of attractive food smells can block the health benefits of dietary restriction in multiple model organisms. While it is known that sensory perception and cell nonautonomous signaling can modulate health and longevity, our knowledge of the specific sensory cues and mechanistic pathways that define this signaling is still limited. Here we find that the sense of touch interacts with nutritional state to modulate lifespan in Caenorhabditis elegans. Worms subjected to dietary restriction are shorter-lived when they perceive tactile stimuli that mimic bacterial food and/or protective soil. Touch modulation of dietary restriction requires putative mechanoreceptor proteins, the neurotransmitters dopamine and tyramine/adrenaline, and the neuropeptides INS-11 and GnRH. Ultimately, the touch circuit regulates the longevity effectors DAF-2/IGF1R and FMO-2/FMO5. These results establish a physiological touch circuit and connect neural reward pathways to the growth and reproductive axes. Finding that texture mechanosensation can modulate longevity suggests a role for touch in lifespan.","PeriodicalId":20548,"journal":{"name":"Proceedings of the National Academy of Sciences of the United States of America","volume":"42 1","pages":"e2423780122"},"PeriodicalIF":11.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Injury induces SerpinB3 expression in vitro and in vivo in the migrating epidermal tongue; overexpression of the protein promotes epithelial-to-mesenchymal transition-like changes. Recombinant Serpinb3a, the mouse ortholog, enhances re-epithelialization in vitro and accelerates wound closure and collagen remodeling in vivo.

O-Glucose glycans are transferred to serine residues located between the first and second conserved cysteines within the epidermal growth factor-like (EGF) repeats in the Notch extracellular domain. Previously, O-glucose glycans were shown to be extended to a trisaccharide structure with two xyloses via α1-3 linkages. Our recent studies, however, indicated that the O-glucose glycan on NOTCH1 EGF10 can be extended by hexose and Neu5Ac. Here, we demonstrated that this hexose- and Neu5Ac-extended glycan has a 3'-sialyllactose-like structure synthesized by specific members of two isoenzyme families, B4GALT1 and ST3GAL4. Using mass spectrometry, we identified this modification exclusively on NOTCH1 EGF10 and the analogous NOTCH3 EGF9 domain, with no detection in any other EGF domains in NOTCH1, NOTCH2, and NOTCH3. Sequence comparison and mutagenesis experiments identified one amino acid at position -2 of the fourth cysteine (C4-2) in the EGF domain as crucial for the galactose elongation of O-glucose glycans. We further demonstrated that this site-specific elongation of O-glucose on NOTCH1 EGF10 significantly impacts ligand binding and signal transduction of NOTCH1. In the context of early T cell development, the C4-2 mutants NOTCH1 A396Y and A396F enhance T cell differentiation through DLL1- and DLL4-dependent NOTCH1 signaling.

DAG can be enzymatically transformed into phosphatidic acid (PA) and accumulated at the PM. PYK2 N-terminal domain-interacting receptor 2 (Nir2) mediates the formation of ER-PM membrane contact sites (MCSs) by specifically recognizing PA at the PM and directly interacting with ER membrane protein vesicle-associated membrane protein-associated proteins (VAPs). The N-terminal phosphatidylinositol transfer protein domain of Nir2 facilitates PI/PA exchange at ER-PM MCSs to maintain PI and PA levels. Here, we reveal the mechanisms by which Nir2 senses phosphatidic acid (PA) and associates with membranes, based on three crystal structures of its C-terminal Lipin/Ned1/Smp2 (LNS2) domain bound to PA, the diphenylalanine [FF]-containing acidic tract (FFAT) motif complexed with vesicle-associated membrane protein-associated protein B/C (VAPB), and the Asp-Asp-His-Asp (DDHD) domain. The C-terminal LNS2 domain of Nir2 directly interacts with the phosphate in the headgroup of PA via hydrogen bonds involving S1025, T1065, K1103, and K1126. Formation of a salt bridge between E355 in Nir2 and R55 in VAPB is essential for Nir2 FFAT-VAPB interaction. The central DDHD domain of Nir2 forms a twofold symmetric dimer, and this self-association contributes to stable and tight membrane association. These findings reveal how Nir2-mediated ER-PM MCS formation maintains continued PI(4,5)P2-dependent PLC signaling.","PeriodicalId":20548,"journal":{"name":"Proceedings of the National Academy of Sciences of the United States of America","volume":"2 1","pages":"e2516849122"},"PeriodicalIF":11.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, male embryos from the reciprocal cross maintain normal expression level of C. nigoni xol-1 genes, consistent with their viability. We further demonstrate that the cis-regulatory regions of Cbr-xol-1 and Cni-xol-1 have functionally diverged. Finally, X transcription is also aberrantly repressed in lethal hybrid male embryos from crosses between gonochoristic species C. latens and C. remanei.

Here, we report a nascent RNA-dependent PHF19-YTHDC1 condensate capable of switching EZH2-mediated gene suppression to activation during prostate cancer progression. We found that the long isoform of PRC2 accessory subunit PHF19, PHF19L, was highly expressed in advanced prostate cancer that promoted the tumor progression and hormonal therapy resistance. Mechanistically, PHF19L was recruited to the m6A modified nascent RNA through YTHDC1 and formed a liquid-like YTHDC1-PHF19L condensate that pulled the EZH2 away from chromatin, resulting in reduced H3K27me3 deposition and the activated expression of EZH2-repressed genes.

As these systems utilize germline encoded receptors, the mechanisms underlying allelic discrimination are unknown. The invertebrate chordate, Botryllus schlosseri, undergoes a natural transplantation reaction controlled by a highly polymorphic, polygenic locus (called the fuhc) with over 1,000 allelic haplotypes found worldwide. Two individuals are compatible if they share one or both fuhc alleles, and we had found that polymorphic discrimination is due to the integration of signals from two allorecognition receptors encoded within the fuhc locus, called fester and uncle fester. Here we show that these two receptors are members of an extended family consisting of >35 genes, now called the Fester family (FF), and coexpressed with members of another diverse gene family, the fester coreceptors (FcoR). Both FF and FcoR are Immunoglobulin superfamily members and each FcoR encodes conserved tyrosine signal transduction motifs, including ITIMs or hemITAMs. FF and FcoR are expressed and encoded as cognate pairs in two polymorphic haplotypes: one within the fuhc locus, and another on a separate chromosome, and remarkably, copy number variation between haplotypes is of gene pairs. Furthermore, two FcoR genes can swap ITIMs and hemITAMs by alternative splicing, suggesting that dynamic tuning of activating and inhibitory signaling is required for allelic discrimination. These results indicate that conserved signal processing mechanisms are the foundation of both allelic discrimination in Botryllus, and recurring convergent evolution of allorecognition receptors observed from invertebrates to mammals.","PeriodicalId":20548,"journal":{"name":"Proceedings of the National Academy of Sciences of the United States of America","volume":"16 1","pages":"e2519372122"},"PeriodicalIF":11.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an effort to understand the genetics underlying breast cancer in these families, we evaluated 136 such families for coinheritance of breast cancer with each of 79 common variants reported as high-confidence \"risk alleles\" for breast cancer by meta-analyses of genome-wide association studies. Simulations based on allele frequencies and family structures revealed one (and only one) of these 79 variants to cosegregate with breast cancer in the families significantly more frequently than expected by chance. This variant (rs2046210) is located 180 kb proximal to ESR1, encoding the estrogen receptor alpha. Reporter assays in MCF7 cells revealed enhancement by the genomic segment at this site of activity of ESR1 promoters, but no difference in effect among alternative haplotypes. In contrast, the 600 kb genomic region including ESR1 and rs2046210 harbored 11 rare variants, each of which cosegregated with breast cancer in one or a few families. For 9 of these 11 variants, reporter assays indicated significant allele-specific effects on ESR1 promoters, with the breast-cancer-linked allele of each variant yielding higher promoter activity. At the site with the most striking effect, the breast-cancer-linked allele was associated with increased binding by transcription factor AP2-gamma TFAP2C in both MCF7 and T47D cells. These results demonstrate coinheritance with breast cancer of rare alleles that increase activity of ESR1 promoters, and suggest that rare ESR1 regulatory alleles may contribute to inherited predisposition to breast cancer.","PeriodicalId":20548,"journal":{"name":"Proceedings of the National Academy of Sciences of the United States of America","volume":"73 1","pages":"e2517736122"},"PeriodicalIF":11.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the early stages of JEV infection in the mouse brain employing a highly multiplexed spatial transcriptomics platform to map viral RNA and host gene expressions in intact brain sections at a single-cell resolution. Although JEV RNA was undetectable in brain sections at 1-day postinfection (dpi), innate immune responses were transiently activated across the brain. At 4 dpi, we detected limited viral RNA and mapped its spatial distribution, identifying glial cells surrounding microvessels as early targets of brain infection. We further characterized transcriptional changes in infected and surrounding bystander cells, revealing cell-type-specific antiviral responses. Notably, JEV neuroinvasion led to the downregulation of endothelial tight junction genes, indicative of an early event that precedes BBB impairment during subsequent disease progression. Our spatial transcriptomic analysis provides insights into cell-type- and region-specific responses to JEV infection, and highlights the early role of glial cells in shaping the immune response landscape of the brain.
