Cancer&Entry Information

Cancer Name	non small cell lung cancer
ICD-0-3	C34
Methods	qPCR, Western blot, in vitro knockdown
Sample	Human normal lung cell line (BESA-2B) and NSCLC cell lines (95D, A549, H1299, H460, and H1975), NSCLC and adjacent non-tumor lung tissues
Expression Pattern	up-regulated
Function Description	the expression of both TMPO-AS1 and TMPO mRNA levels were overexpressed in NSCLC cells lines and tissues. A significant positive correlation was observed between TMPO-AS1 and TMPO mRNA levels. The upregulation of TMPO-AS1, TMPO mRNA and protein levels were associated with tumor progression of NSCLC. More importantly, through antisense pairing with TMPO mRNA, TMPO-AS1 regulates TMPO mRNA stability. Knockdown of TMPO-AS1 decreased the mRNA and protein levels of TMPO in NSCLC cells. An overlapping (OL) region was found between TMPO-AS1 and TMPO exon 1 and overexpression of TMPO-AS1-OL elevated the mRNA and protein levels of TMPO. Functionally, the downregulation of TMPO-AS1 significantly inhibited cells proliferation, colony formation, migration and invasiveness in vitro, and tumor growth in vivo. In contrast, overexpression of TMPO could promote the aggressive behaviors of NSCLC cells in vitro.
