CCND1 and non-small cell lung carcinoma: Another similar study found cell cycle progression was also slowed down by miR-146a via specifically downregulating the expression of CCND1/2 (genes of cyclins D1/2), both at post-transcriptional and protein stages that arrested the G0/G1 phase of cell cycle progression [63] and targeted cyclin J that promoted NSCLC chemosensitivity to cisplatin [64].
