摘要: While estrogen receptor β (ERβ) may impact the progression of non-small cell lung cancer (NSCLC), its linkage to alteration vasculogenic mimicry (VM) formation influence NSCLC invasion remains unclear. Here, we analyzed immunohistochemistry data from tissues and found that ERβ-positive female patients had worse survival outcomes than those ERβ-negative patients. In vitro studies using multiple lines also revealed ERβ could increase VM invasion. Molecular mechanism dissection suggested lncRNA-MALAT1 (MALAT1) expression via directly binding response elements (EREs) located on promoter MALAT1, which then lead (i) suppressing miR145-5p (ii) increasing NEDD9 protein as can target 3'-UTR NEDD9-mRNA. A preclinical study in vivo mouse model further confirmed data. Together, results above demonstrated promote altering ERβ/MALAT1/miR145-5p/NEDD9 signaling. Targeting this newly identified signaling pathway with small molecules help development novel therapies better suppress metastasis.
