Endocrinology . 2025 Jan; 166(2). PMID: 39834231
This study uncovers a dynamic shift in estrogen receptor expression during granulosa cell (GC) differentiation in the ovary, highlighting a transition from estrogen receptor alpha (ESR1) to estrogen receptor beta...

Biol Reprod . 2024 Feb; 110(5):1025-1037. PMID: 38381622
Prenatal exposure to Di (2-ethylhexyl) phthalate (DEHP) impairs the reproductive system and causes fertility defects in male offspring. Additionally, high-fat (HF) diet is a risk factor for reproductive disorders in...

Ko C, Cho Y, Ham E, Cacioppo J, Park C
Reproduction . 2022 Feb; 163(4):R71-R80. PMID: 35167488
Ovulation is the fundamental biological process during which an oocyte is expelled from the ovary, and it is an essential step toward establishing a pregnancy. Understanding regulatory mechanisms governing the...

Park C, Lin P, Zhou S, Barakat R, Bashir S, Choi J, et al.
Cell Rep . 2020 Apr; 31(2):107496. PMID: 32294429
Ovulation is triggered by the gonadotropin surge that induces the expression of two key genes, progesterone receptor (Pgr) and prostaglandin-endoperoxide synthase 2 (Ptgs2), in the granulosa cells of preovulatory follicles....

Barakat R, Lin P, Park C, Zeineldin M, Zhou S, Rattan S, et al.
Sci Rep . 2020 Apr; 10(1):5705. PMID: 32235866
In males, defective reproductive traits induced by an exposure to an endocrine disruptor are transmitted to future generations via epigenetic modification of the germ cells. Interestingly, the impacted future generations...
