MiR-10b was highly expressed in monotocous goat ovaries.
Brain-derived neurotropic factor (BDNF) was highly expressed in polytocous goat ovaries.
Human chorionic gonadotropin induced a transient expression of BDNF in granulosa cells.
Human chorionic gonadotropin upregulated miR-10b expression in a time-dependent manner.
MiR-10b inhibited granulosa cell proliferation by targeting BDNF.
