Mechanism of ovarian carcinogenesis: effect of 7,12-dimethylbenz[a]anthracene administration on intrasplenic ovarian grafts in unilaterally ovariectomized C3HeB/Fe mice. 1979

V Armuth, and I Berenblum

A single oral administration of 7,12-dimethylbenz[a]anthracene (DMBA) 2 weeks after intrasplenic grafting of ovarian tissue in unilaterally ovariectomized C3HeB/Fe mice resulted in a high tumor incidence (47%) in the grafted tissue, with only 1 tumor (3%) in the orthotopic ovary. No tumors were seen in the control group (unilaterally ovariectomized mice given intrasplenic grafts of ovarian tissue without subsequent DMBA administration), nor did tumors develop in response to DMBA treatment in mice with both ovaries in situ and no grafted tissue in the spleen. The results indicated that some local change caused by the grafting procedure rendered the tissues more sensitive to the action of DMBA and/or more responsive to gonadotropic stimulation.

D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.

D002369	Castration	Surgical removal or artificial destruction of gonads.	Gonadectomy,Castrations,Gonadectomies
D005260	Female		Females
D006065	Gonadotropins, Pituitary	Hormones secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR) that stimulate gonadal functions in both males and females. They include FOLLICLE STIMULATING HORMONE that stimulates germ cell maturation (OOGENESIS; SPERMATOGENESIS), and LUTEINIZING HORMONE that stimulates the production of sex steroids (ESTROGENS; PROGESTERONE; ANDROGENS).	Pituitary Gonadotropins
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
