Effects Of Bisphenol-S And Estrogen On P53 Expression In Ovarian Tissue Of Zebrafish (Danio Rerio), Jess Fairbanks
Effects Of Bisphenol-S And Estrogen On P53 Expression In Ovarian Tissue Of Zebrafish (Danio Rerio), Jess Fairbanks
Summer Research
Bisphenol A (BPA) is one the most widely used plasticizing compounds. As an endocrine disruptor, BPA could affect ovarian function and embryonic development. Bisphenol S (BPS) has been used in many plastics and resins in lieu of BPA. However, the effects of BPS are not widely known. Apoptosis is a type of genetically programmed cell death that is important in ovarian homeostasis. One of the genes that regulates apoptosis, p53, has been shown to respond to estrogen in maintaining ovarian homeostasis. We have investigated how exposure to estrogen and to BPS affects p53 expression in ovarian tissue in vitro …

The hypothalamic-pituitary-gonadal (HPG) axis is responsible for the production of the hormones testosterone and estradiol, and testosterone is thought to contribute to regulation of the axis through a negative feedback mechanism. Regulation by negative feedback involves the product of a pathway turning off that pathway when enough product is made. However, because the enzyme P450 aromatase converts testosterone to estradiol, estradiol may also contribute to regulation of the HPG axis and other phenomena that have been attributed to testosterone, like the inhibition of immune function. Previous studies have injected birds with an aromatase inhibitor (presumably reducing estradiol production) and shown …
