PTBP3 and non-small cell lung carcinoma: A recent study suggested that PTBP3 promotes migration of non-small cell lung cancer (NSCLC) cells by regulating E-cadherin in the epithelial–mesenchymal transition signalling pathway and that there was a significant association between high PTBP3 expression in NSCLC tissues with poor OS (Wu et al., 2020).
