KLF9 and polycystic ovary syndrome: In the present study, to further verify the role of hepatic KLF9 in the development of PCOS, we crossed Rosa26 Klf9fl/fl mice with Alb‐cre mice to generate hepatocyte‐specific Klf9 transgenic mice (Alb‐Cre+; Rosa26 Klf9fl/+, hereafter named LTg); littermates lacking the Cre gene were used as controls (Alb‐Cre−; Rosa26 Klf9fl/+, hereafter named LCtr).
