This research study focuses on the relevance of hsa_circ_515 (circ_515) to non-small cell lung cancer (NSCLC) progression and the downstream targets involved. Differentially expressed circRNAs in NSCLC were screened using a GSE158695 dataset. Circ_515 was overexpressed and indicated poor outcomes in patients with NSCLC. Knockdown of circ_515 repressed proliferation and invasiveness, while potentiated cell cycle arrest and apoptosis of NSCLC cells, and upregulation of circ_515 led to converse trends. The candidate downstream transcripts of circ_515 were explored using integrated bioinformatic analyses. Ectopic expression of miR-296-5p reduced the malignance of NSCLC cells. Circ_515 sequestered miR-296-5p and blocked its suppressive role in RING finger protein 44 (RNF44) expression. Downregulation of RNF44 counteracted the oncogenic effects of circ_515. In vivo, the anti-tumor effects of circ_515 knockdown were reversed by miR-296-5p, while the tumor-promoting effects of circ_515 upregulation were abolished by RNF44 knockdown. All in all, our findings demonstrate that circ_515 sequesters miR-296-5p and elevates RNF44 expression to encourage the NSCLC progression. This study might provide new thoughts on NSCLC management.</p>","PeriodicalId":15226,"journal":{"name":"Journal of Cell Communication and Signaling","volume":"19 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ccs3.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481515","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}

Oxidative stress and inflammation in retinal Müller cells participate in the pathogenesis of DR. This work aims to study the biological role of moscatilin in the progression of DR and the underlying mechanism. High glucose (HG)-stimulated mouse primary retinal Müller cells and high-fat diet + streptozotocin (STZ)-induced DR mouse models were constructed as in vitro and in vivo models, respectively. The effects of moscatilin treatment on oxidative stress and inflammation in HG-stimulated Müller cells and DR mice were evaluated by detecting intracellular reactive oxygen species production, malondialdehyde levels, superoxide dismutase and catalase activities, glutathione/oxidized glutathione ratio, as well as proinflammatory cytokine levels through CM-H₂DCFDA staining, commercial kits, and enzyme-linked immunosorbent assay. Dual immunofluorescence staining of glial fibrillary acidic protein and vimentin was used to evaluate the development of Müller cells in mouse retinas. The activity of p38 mitogen-activated protein kinase (MAPK)/c-Jun N-terminal kinase (JNK) and nuclear factor kappa-B (NF-κB) signaling pathway was assessed through western blotting and immunofluorescence staining. Moscatilin pretreatment prevented HG-induced decrease in Müller cell viability. Moscatilin mitigated oxidative stress, inflammation, and extracellular matrix remodeling in HG-stimulated Müller cells and DR mice. Mechanically, moscatilin reduced the levels of receptor for advanced glycation end products, phosphorylated I-kappa-B-alpha, p-p65 NF-κB, p-p38 MAPK, and p-JNK in both HG-stimulated Müller cells and DR mice. Moscatilin plays an antioxidant and anti-inflammatory role in DR by inhibiting the p38 MAPK/JNK and NF-κB signaling pathways.</p>","PeriodicalId":15226,"journal":{"name":"Journal of Cell Communication and Signaling","volume":"19 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ccs3.12059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446958","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}

It is also established that the CaSR is present in tissues previously thought to be noncalcitropic and this review discusses the role of the CaSR in vascular function, focusing mainly on contractility but also outlining its role in cell proliferation and calcification. Stimulation of the CaSR by extracellular Ca²⁺ concentration ([Ca²⁺]_o) on perivascular sensory nerves and vascular endothelial cells is associated with vasodilatation through the release of vasoactive substances and stimulation of IK_Ca channels and nitric oxide synthesis, respectively, which mediate endothelium-derived hyperpolarizations and activation of BK_Ca channels and K_ATP channels in vascular smooth muscle cells (VSMCs). CaSR-induced vasoconstrictions are mediated by the CaSR expressed in VSMCs, which are coupled to the G_q/11 protein-coupled pathway. In addition, the CaSR expressed on VSMCs also regulates proliferation and calcification. Consequently, the CaSR has been implicated in regulating systemic and pulmonary blood pressure and calcimimetics and calcilytics are potential therapeutic targets for cardiovascular diseases, such as hypertension, pulmonary artery hypertension, and atherosclerosis.</p>","PeriodicalId":15226,"journal":{"name":"Journal of Cell Communication and Signaling","volume":"19 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ccs3.70004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248753","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}

Furthermore, CCN2 knockdown caused a significant accumulation of cells in G1/G0 phase and blocked entry into S-phase. Mechanistically, CCN2 knockdown blocked cyclin E and CDK4/cyclin D nuclear translocation, and abrogated CDK2 activity. Markedly, CCN2 translocated to the nucleus and co-localized with cyclin D1 upon cell cycle stimulation. Finally, we show that CCN2, a bona fide YAP/TAZ target gene, partially mediates YAP/TAZ-dependent proliferation of primary HDFs.

The interaction between Zinc finger E-Box binding homeobox 2 (ZEB2) and TCF7L2 was analyzed by Co-IP, and H3K27ac enrichment in the TCF7L2 promoter was detected by ChIP assay.
