Short summary
There are few studies investigating the RNA-binding protein Lin28B and ovine puberty. This study focuses on understanding how its overexpression changes microRNA levels, cell proliferation, and estrogen secretion. To assess these changes, we used quantitative real-time (qRT) PCR, overexpression vectors, and ELISA. We found that Lin28B overexpression decreases let-7b and let-7g levels and increases granulosa cell proliferation and their estrogen secretion.
