Here, we show that the human Golgi transmembrane protein TM9SF3 is a receptor essential for Golgiphagy under nutrient-stress and multiple Golgi-stress conditions. TM9SF3 binds all six mammalian ATG8 proteins through its N-terminal LC3-interacting regions. In U2OS cells, <em>TM9SF3</em> knockout blocks nutrient-stress-induced Golgi fragmentation and reduces the targeting of Golgi fragments to autophagosomes, resulting in decreased Golgi protein degradation. Beyond nutrient stress, TM9SF3 is required for Golgiphagy induced by monensin, brefeldin A, and disruptions in intra-Golgi protein glycosylation. Knockout of <em>TM9SF3</em> and mutations in its LC3-interacting regions (LIRs) both compromise protein glycosylation, whereas <em>TM9SF3</em> overexpression promotes degradation of incompletely glycosylated proteins. Further, we show that TM9SF3 is required for human breast cancer cell proliferation, and high TM9SF3 levels are associated with poor prognosis, implicating its function in breast cancer pathology.","PeriodicalId":11157,"journal":{"name":"Developmental cell","volume":"570 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533893","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}

Radiation of the entire brain is highly effective in the treatment and/or prevention of medulloblastoma leptomeningeal metastases. Infants treated on clinical trials with focal tumor radiation recur metastatically, whereas infants treated with only chemotherapy relapse locally. In murine medulloblastoma model systems, provision of a single dose of radiation to the tumor drives leptomeningeal dissemination. An inflammatory response after radiation-induced tumor cell death recruits a variety of immune cells. Inflammation opens the local blood-brain barrier, allowing intravasation of medulloblastoma cells. Experimental induction of inflammation with lipopolysaccharide drives medulloblastoma leptomeningeal dissemination, whereas premedication with corticosteroids prevents both inflammation and the pro-metastatic effect of radiation. In murine model systems, inflammation in the tumor microenvironment secondary to external beam radiation is both sufficient and necessary to drive leptomeningeal metastases.","PeriodicalId":11157,"journal":{"name":"Developmental cell","volume":"3 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533894","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}

Here, using biophysical approaches, we investigate how muscles under the epidermis specifically stimulate the extension of anterior-posterior (AP)-oriented epidermal adherens junctions during late <em>C. elegans</em> embryonic elongation. First, light-sheet imaging shows that asynchronous patterns of muscle contractions drive embryo rotations. In turn, junctions between the lateral and dorso-ventral epidermis repeatedly oscillate between a folded, hypotensed state and an extended, hypertensed state. Second, fluorescence recovery after photobleaching (FRAP) analysis of an E-cadherin::GFP construct shows that muscle contractions stimulate E-cadherin turnover. Moreover, a mechano-chemical model backed by genetic tests suggests that E-cadherin trafficking controls junction elongation due to lower line tension. Altogether, our results illustrate how muscle contractions fluidize epidermal adherens junctions, which, combined with anisotropic tension in the epidermis, drive their polarized extension.","PeriodicalId":11157,"journal":{"name":"Developmental cell","volume":"6 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533898","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}

Several important splicing factors were identified in cardiomyocytes, including members of the RNA-binding proteins with multiple splicing (RBPMS) family, but their role during heart development has not been fully characterized. Here, we demonstrate that the function of RBPMS overlaps with the closely related paralog RBPMS2. <em>Rbpms</em>-deficient cardiomyocytes exhibit a higher degree of binucleation at birth, but this does not affect heart function in mice substantially until late adulthood. In contrast, <em>Rbpms</em>/<em>Rbpms2</em> (<em>Rbpms/2</em>) compound mutants show pronounced disruption of the splicing network in embryonic cardiomyocytes, which leads to the formation of defective nuclei and disruption of sarcomere structures, eventually resulting in embryonic lethality. We demonstrate that mitotic defects in embryonic <em>Rbpms/2</em>-deficient cardiomyoctes are caused by the disbalance of nuclear and cytoplasmic calcium (Ca<sup>2+</sup>)/CaM-dependent protein kinase II gamma (<em>Camk2g</em>) isoforms. Overexpression of the <em>Rbpmsa</em> isoform partially rescues these defects, preventing embryonic lethality of <em>Rbpms/2</em>-deficient mice, and is sufficient for cardiomyocyte-specific splicing in other cell types.","PeriodicalId":11157,"journal":{"name":"Developmental cell","volume":"152 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520834","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}

A single-cell transcriptomic atlas identified that <em>npas4l</em> was dynamically expressed in platelets after heart injury and controlled robust interactions between platelet-CMs or -ECs. Decreasing platelets impaired CM/EC proliferation, and overexpression of <em>npas4l</em> in platelets sufficiently induced CM/EC proliferation in uninjured hearts, as well as rescued CM/EC proliferation defects in <em>cloche</em> mutants. Mechanistically, Npas4l positively controlled a panel of ligand expression, including <em>bmp6</em> in platelets, to fine-tune CM proliferation and heart regeneration.

A knockin endogenous reporter shows that NGN3 protein oscillates with a 13-h periodicity in human induced pluripotent stem cell (hiPSC)-derived endocrine progenitors and is switched off as cells differentiate to β-like and pre-α cells. Increasing NGN3 protein stability results in one broad peak of expression instead of oscillations, with a larger peak-to-trough fold-change. This leads to precocious endocrine differentiation and earlier expression of key NGN3 target genes. Single-cell analysis of dynamics, mathematical modeling, and experimental validation suggest that NGN3 oscillations are decoded by fold-change detection (FCD) rather than the level of expression via an incoherent feedforward loop (IFFL) motif that explains both normal and precocious differentiation.
