Effects of corticosterone on the expression of mature brain-derived neurotrophic factor (mBDNF) and proBDNF in the hippocampal dentate gyrus.

•Corticosterone (CORT) administration induced depressive-like behavior in rats.•CORT modulated the mature BDNF and proBDNF expression differentially in the dorsal and ventral hippocampal DG.•CORT modulated the Bdnf gene transcription differentially in the hippocampal DG.
