About The Cover

Online Cover This week features a Research Article that shows that altering the relative abundance of the progesterone receptor isoforms PgrA and PgrB in mice causes ovarian cancer, suggesting that similar imbalances observed in reproductive tract cancers in women may drive tumorigenesis. The image shows a hematoxylin and eosin–stained section of a neoplastic ovary from a mouse overexpressing PgrB in the reproductive tract. [Image: F. J. DeMayo/NIEHS]
