The above article, published online on April 25, 2018, in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the journal Editor-in-Chief, Robert Heath, and Wiley Periodicals LLC. Concerns were raised to the journal editorial office, as well as on PubPeer [1], regarding multiple duplicated images in the figures. Following investigation, evidence of duplication was found within Figure 2A; between Figure 2A of this article and Figure 2B of a different article by some of the same authors [Shu et al. 2017: https://doi.org/10.1038/s41598-017-07633-7]; and between Figure 4A of this article and Figure 3 of a different article by some of the same authors [Tian et al. 2017: https://doi.org/10.1038/cddis.2017.2]. The authors cooperated with the investigation and sent a proposed correction, but this was not considered sufficient to resolve the concerns. The editor has lost confidence in the results reported, and therefore, the article must be retracted. The authors disagree with the decision. Reference: [1] B.

In this study, we established cellular senescence models of human small intestinal organoids using two senescence-inducing agents: butyrate (an endogenous microbial metabolite) and cisplatin (an exogenous chemotherapeutic agent). Both molecules induced senescence-associated features, including increased p16INK4a, CDKN1A, IL8, and TNF expression, as well as SA-β-Gal activity. RNA-sequencing revealed that cisplatin, but not butyrate, activated the p53 signaling pathway, whereas both downregulated various nutrient absorption and metabolism-related pathways.

In cisplatin-treated organoids, epithelial to mesenchymal transition (EMT)-related gene ontologies were enriched based on RNA-sequencing. The induction of EMT through cisplatin-induced senescence was further confirmed by EMT marker gene expression, which decreased following the inhibition of TGF-β signaling, a canonical EMT-inducing pathway. Notably, TGF-β signaling inhibition attenuated senescence-induced inflammation and nutrient dysfunction, which suggests the importance of EMT as a target for preventing intestinal senescence.

In myoblasts, Transient Receptor Potential Canonical (TRPC) channels, with TRPC1 as a predominant isoform, mediate store-operated Ca²⁺ entry (SOCE) and are essential for myogenesis. PDLIM5 (ENH1), a PDZ-LIM scaffold protein, organizes signaling events, including ion channel regulation and transcriptional control in muscles. This study aims to test the hypothesis that PDLIM5 regulates TRPC1-mediated Ca<sup>2+</sup> entry in myoblasts. Thapsigargin-induced SOCE was suppressed by the SOCE inhibitors Gd<sup>3+</sup> and 2-APB, as well as by TRPC1 siRNA, supporting the involvement of TRPC1 in SOCE in C2C12 myoblasts. Additionally, SOCE inhibition decreased the number of nuclei per myotube and reduced the size of myotubes. ENH1 siRNA knockdown significantly downregulated TRPC1 and STIM1 mRNA expression, increased basal cytosolic Ca<sup>2+</sup> level, and impaired SOCE response and myotube maturation. Overexpression of ENH4, a skeletal muscle-specific short splice variant of ENH1, similarly repressed TRPC1-mediated SOCE and myotube formation. Conversely, ENH1 overexpression enhanced SOCE without altering the mRNA levels of TRPC1, Orai1, or STIM1. Immunoprecipitation showed a physical interaction between ENH1/ENH4 and TRPC1. In differentiated myotubes, TRPC1 also contributed to thapsigargin-induced SOCE, as evidenced by the reduced Ca<sup>2+</sup> entry following TRPC1 knockdown. ENH1 knockdown and ENH4 overexpression significantly attenuated SOCE in myotubes; notably, ENH1 knockdown also increased basal cytosolic Ca<sup>2+</sup> level. In contrast to myoblasts, ENH1 overexpression did not enhance SOCE in myotubes, concomitant with the absence of a detectable interaction between ENH1 and TRPC1, whereas ENH4 retained its association with TRPC1. These findings suggest that ENH1 and ENH4 differentially modulate TRPC1-dependent Ca<sup>2+</sup> entry in C2C12 cells, thereby regulating myogenic differentiation and contributing to skeletal muscle formation and development.</p>","PeriodicalId":15220,"journal":{"name":"Journal of Cellular Physiology","volume":"241 5","pages":"e70173"},"PeriodicalIF":4.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147838525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knockdown of SGK1 via siRNA or pharmacological inhibition disrupts spindle assembly and impairs kinetochore-microtubule attachments in mouse oocytes. This disruption leads to sustained activation of the spindle assembly checkpoint, failure of Cyclin B1 and Securin degradation, impaired metaphase I-anaphase transition, and defective first polar body extrusion. Mechanistically, we identify RanBP1 as a potential mediator of SGK1 function during meiotic progression. In porcine oocytes, SGK1 inhibition similarly compromises maturation and Cyclin B1 degradation, suggesting a conserved role across mammalian species.

These stones interact with the surface of renal epithelial cells and initiate injury. In differentiated renal epithelial cells (DREC), we demonstrated that oxalate (Oxa) injures monolayers, which undergo a type II epithelial-mesenchymal transition during the first 24 h (the damage period). Thereafter, cells gradually recover their morphology, restituting the monolayer between 48 and 72 h (the restitution period). Since Oxa induces lipid peroxidation (LPO), which disrupts membrane homeostasis, we hypothesize that epithelial restitution occurs after the activation of lipid metabolism and the restoration of cellular membrane integrity. The goal of this study was to determine the role of glycerolipid (GL) metabolism in DREC monolayer survival and restitution after Oxa injury. DREC monolayers were incubated with 1.5 mM Oxa during the damage and the restitution periods. After the damage period, we found alterations in the DREC monolayer and a decrease in cell number. Moreover, Oxa-induced LPO changes membrane composition and properties. These changes were accompanied by the activation of glycerophospholipid (GP) and triacylglyceride (TG) synthesis and by an increase in the number of lipid droplets (LD), but a decrease in their size. The inhibition of lipin activity impaired GP and TG synthesis, completely preventing DREC monolayer restitution. Collectively, these results demonstrate that Oxa-induced LPO disrupts DREC membrane properties, changing their biophysics and composition, which affects cell physiology.

PGRN critically shapes the inflammatory and stromal landscape that sustains tumor growth. This review aims to comprehensively summarize current knowledge on the multifaceted roles of PGRN within the TME, with a particular focus on its functions in immune and stromal cells that contribute to tumor progression and immune evasion. In fact, it reprograms TME toward an immunosuppressive state by activating signaling pathways such as TNFR2/STAT3 and PI3K/AKT. It promotes M2-like macrophage polarization, enhances PD-L1 expression, supports regulatory T-cell stability, and suppresses CD8⁺ T- and NK-cell cytotoxicity, and fosters immune evasion. Simultaneously, PGRN affects stromal components by activating cancer-associated fibroblasts (CAFs), remodeling the extracellular matrix, and stimulating angiogenesis. These coordinated actions position PGRN as a central orchestrator of tumor-associated inflammation. Despite these insights, its roles in myeloid-derived suppressor cells, neutrophils, and other stromal subsets remain poorly understood. Therefore, investigating PGRN's influence on these cells is crucial for understanding tumor progression and therapeutic resistance and may reveal novel strategies to disrupt PGRN-dependent inflammatory circuits and enhance anti-tumor immunity.</p>","PeriodicalId":15220,"journal":{"name":"Journal of Cellular Physiology","volume":"241 5","pages":"e70188"},"PeriodicalIF":4.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147868593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
