ALI culture of ELC-org-mono greatly developed goblet cells and enhanced the gene expression levels of many drug-metabolizing enzymes, drug transporters and intestinal differentiation markers. However, their activities were not enhanced. RNA-seq analysis suggested that ALI culture increased the expression of genes related to metabolic processes but decreased glycolytic processes. Analysis of glycolytic capacity confirmed that ALI culture decreased glycolytic activities.

Thus, it becomes critical to identify novel factors and their mechanism of action in regulating the adhesion and migration of MSCs under nutrient stress condition for successful clinical application. In human placenta-derived MSCs (PL-MSCs), we demonstrated an increase in cell spread area, along with increased adhesion and reduced migration of the cells, when cultured under nutrient stress condition. Correspondingly, an increase in the total number per cell and size of focal adhesions (FAs), together with prominent stress fibers were observed in nutrient-stressed PL-MSCs compared to control PL-MSCs. The FAs were demonstrated to be more stable, exhibiting slower turnover and longer lifespan. Vitronectin (VTN), an ECM glycoprotein, was upregulated under nutrient stress condition. Knockdown of VTN in PL-MSCs led to a significant reduction in the total number per cell and size of FAs, along with their faster turnover and shorter lifespan. Subsequently, a reversal in the cell spread area, adhesion and migration properties of the nutrient-stressed PL-MSCs were noted. Additionally, our findings indicated that VTN, as an upstream regulator, stimulated the phosphorylation of myosin light chain, which possibly promoted the maturation and stability of FAs along with assembly of stress fibers, thereby leading to increased adhesion and reduced migration of the cells. Overall, our study defines a distinct role of VTN as a critical regulator of migration in PL-MSCs under nutrient stress condition.</div></div>","PeriodicalId":12010,"journal":{"name":"European journal of cell biology","volume":"104 2","pages":"Article 151477"},"PeriodicalIF":4.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143079013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously showed that a down-regulation of FHIT causes an up-regulation of the activity of HER2 associated to an epithelial-mesenchymal transition (EMT) and that lung tumor cells harboring a FHIT<sup>low</sup>/pHER2<sup>high</sup> phenotype are sensitive to anti-HER2 drugs. Here, we sought to decipher the FHIT-regulated HER2 signaling pathway in NSCLC. Transcriptomic analysis of tumor cells isolated from NSCLC revealed the endocytic receptor low density lipoprotein receptor-related protein 1 (LRP1), a central regulator of membrane trafficking and cell signaling, as a potential player of this signaling. In a cohort of 80 NSCLC assessed by immunohistochemistry, we found a significant association between a low FHIT expression and a high pHER2 and LRP1 expression by tumor cells. Experiments of FHIT silencing showed that FHIT regulated LRP1 expression both at the mRNA and protein levels in lung cell lines. Analyzing the relationship between LRP1 and HER2, we observed that an anti-HER2 targeted therapy reversed LRP1 overexpression induced by FHIT silencing whereas LRP1 silencing did not affect HER2 activity. Studying the functional role of LRP1, we showed that cell proliferation and invasion induced by FHIT silencing were LRP1-dependent. In addition, we found that the induction of vimentin upon FHIT inactivation was counteracted by LRP1 silencing. These results suggest that LRP1 acts downstream of HER2 to induce EMT and tumor progression following FHIT loss. Dual targeting of HER2 and LRP1 might represent a therapeutic strategy to more efficiently inhibit HER2 signaling in FHIT-negative NSCLC.</div></div>","PeriodicalId":12010,"journal":{"name":"European journal of cell biology","volume":"104 1","pages":"Article 151475"},"PeriodicalIF":4.5,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142926874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing Piezo1 activity suppressed <em>klf2a</em> and increased vSMC association with the cardinal vein, while inhibition of Piezo1 activity increased <em>klf2a</em> levels and decreased vSMC association with arteries. We supported the small molecule findings with <em>in vivo</em> genetic suppression of <em>piezo1</em> and <em>2</em> in zebrafish, resulting in loss of <em>transgelin+</em> vSMCs on the dorsal aorta. Further, endothelial cell (EC)-specific <em>Piezo1</em> knockout in mice was sufficient to decrease vSMC accumulation along the descending dorsal aorta during development, thus phenocopying our zebrafish data, and supporting functional conservation of Piezo1 in mammals. To determine the underlying mechanism, we used <em>in vitro</em> modeling assays to demonstrate that differential sensing of pulsatile versus laminar flow forces across endothelial cells changes the expression of mural cell differentiation genes.
