Among these miRNAs, miR‐202 is gonad‐specific and might be important in the prevention of premature ovarian failure (POF) (Sontakke et al.,2014), and miR‐27b and its target, peroxisome proliferator activated receptor gamma (PPARγ), is crucial for the maturation of porcine oocytes (Song et al.,2016). The gene discussed is PPARG; the disease is primary ovarian failure.
