CPEB1 and astrocytoma (excluding glioblastoma): Overexpression of CASC2c promotes the malignant characteristic of astrocytoma cells.CASC2c directly bound miR-101 and mediated pre-miR-101 processing into mature miR-101, and functions as a competitor of miR-101 target genes such as CPEB1. Patients who possessed both low CASC2c and high miR-101 had a longer survival than those of low CASC2c alone or high miR-101 alone.
