CREB1 and cervical cancer: We present convincing evidence showing that serum starvation and CREB1 could increase the transcription of miR-320a, that serum starvation improves the proliferation of HeLa and C33A cervical cancer cells through miR-320a, that miR-320a prolonged the survival of cervical cancer cells, and that repressing the expression of VDAC1 enhanced mitophagy.
