Yet its role in non-small cell lung cancer (NACLC) and underlying mechanism are still unclear. In this study, we found YME1L was highly expressed at both protein and RNA levels in NSCLC tissues, which was consistent with the result of database analysis. The bioinformatics analysis also showed that YME1L expression negatively correlated with survival rate. The significance of YME1L was investigated through gain- and loss-of-function studies in vivo and vitro. As expected, the protease activity was consistent with the expression of YME1L. Knockdown of YME1L significantly inhibited mitochondrial activity, proliferation and migration of NACLC cell lines, and suppressed the growth of xenografted tumors in nude mice. While over-expression of YME1L promoted the development of tumors. Further study revealed that YME1L increased the proportion of S-phase and reduced the number of G0/G1 ratio in NSCLC cells, suggesting the strong proliferation activity. Mechanically, knockdown of YME1L decreased the expression of Gαi1 and the phosphorylation of Akt, and on the contrary, YME1L over-expression increased the Gαi1 expression and Akt activation, which in turn stimulated cell proliferation, migration and survival, and promoted the progression of NSCLC. In this study, we revealed that YME1L played a novel oncogenic role in promoting NSCLC tumorigenesis and progression via the mitochondria-Gαi1-AKT axis, providing a new target for the treatment of lung cancer.</div></div>","PeriodicalId":49225,"journal":{"name":"Cancer Genetics","volume":"298 ","pages":"Pages 212-220"},"PeriodicalIF":2.1,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145410670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among its subunits, laminin γ2 (LAMC2) emerges as a key player in the progression of cancer. This review delves into the current understanding of LAMC2′s role, highlighting its significant contribution to cancer development through promoting cell proliferation, invasion, and vasculogenic mimicry, as well as inhibiting apoptosis. Notably, LAMC2 expression is markedly increased in cancerous tissues compared to normal counterparts, with higher levels of LAMC2 correlating with poorer survival rates. This correlation underscores LAMC2′s potential as a diagnostic and prognostic marker across various cancers. Furthermore, the increasing importance of LAMC2 as a viable target for cancer therapy is explored.
