BACH1 and non-small cell lung carcinoma: Wei et al.12 evaluated the expression of MIR17HG is down-regulated in NSCLC, while the over-expression of MIR17HG can lead to up-regulation of miR-142-3p and down-regulation of Bach-1 expression, thereby inhibiting the invasion and migration ability of non-small cell lung cancer (NSCLC) cells through methylation-specific PCR (MSP) and Transwell invasion and migration tests.
