This polarization is associated with distinct proximal-promoter structures, distinguishing high-paused genes with restricted RNA Pol II pause-release from low-paused genes undergoing rapid RNA Pol II firing into productive elongation.

We observed significant species-specific differences in GCN robustness and dorsal-ventral propensity for progenitor development. Benchmarking three common differentiation protocols against the in vivo datasets showed that they fail to reproduce human-like GCNs, thereby limiting stem cell-derived insulin-secreting β cell (SC-β cell) induction efficiency. To address this, we developed a protocol that reconstructs human pancreatic GCN dynamics, shortens the induction period to 19 days, and achieves up to ∼70% β cell content.

Here, we identify a pathological role for bromodomain-containing 3 (BRD3) in driving septic shock by upregulating aconitate decarboxylase 1 (ACOD1) in monocytes and macrophages via a non-canonical pathway. Mechanistically, lipopolysaccharide triggers an interaction between BRD3 and tripartite motif containing 21 (TRIM21), which activates CREB binding lysine acetyltransferase (CREBBP) via its E3 ligase activity, facilitating CREBBP's binding to and acetylation of cyclic adenosine monophophate (cAMP)-response-element-binding protein 1 (CREB1). BRD3 then recognizes and phosphorylates acetylated CREB1 at the transcription-activating site, thereby upregulating ACOD1 transcription. In four murine models of infection, myeloid-specific Brd3 deletion (Brd3<sup>Mye</sup><sup>-/-</sup>) or pharmacological intervention using small-molecule inhibitor OTX015 confers significant protection, reducing systemic inflammation and organ injury, similar to the effects observed in Acod1<sup>Mye-/-</sup> mice.

To avoid this, flowering plants have intricate polytubey block mechanisms that prevent additional pollen tubes from entering the ovule. In one mechanism for blocking polytubey, the fertilized egg cell secretes the aspartic endopeptidases EGG CELL-SPECIFIC1 (ECS1) and ECS2, which degrade pollen tube attractants. However, the mechanism underlying the egg-cell-specific expression of <em>ECS1</em> and <em>ECS2</em> was unknown. Here, we demonstrate that in <em>Arabidopsis thaliana</em> egg cells, SMALL RNA DEGRADING NUCLEASE (SDN) degrades microRNAs (miRNAs) targeting <em>ECS</em> genes, thereby allowing ECS1 and ECS2 to accumulate in egg cells to establish the polytubey block. Like <em>Arabidopsis ecs1 ecs2</em> mutants, <em>sdn1 sdn2 sdn3</em> mutants exhibited polytubey, as did plants specifically overexpressing miRNAs targeting <em>ECS</em> genes in egg cells.

In this study, we demonstrate that sensory nerves constitute a critical component of the skeletal stem cell (SSC) niche. Deletion of the neurotrophin receptor p75NTR in neurons or sensory-specific cells, but not in osteogenic or sympathetic cells, resulted in reduced sensory innervation, disrupted SSC homeostasis, and significant bone loss. Although a cell-intrinsic role of p75NTR in SSCs cannot be ruled out, further experiments involving sensory denervation or transplantation into hosts with sensory-neuron-specific p75NTR deficiency confirmed impaired SSC osteogenesis. Mechanistically, p75NTR controls the expression of neuronal osteopontin (SPP1), which in turn promotes SSC self-renewal and osteogenic differentiation. Notably, this p75NTR-SPP1 signaling axis was found to be disrupted in AD mouse models, offering a direct mechanistic explanation for AD-associated osteopenia and highlighting the therapeutic potential of targeting neural control of SSCs.","PeriodicalId":11157,"journal":{"name":"Developmental cell","volume":"9 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
