NIH:OVCAR-3 is an appropriate model system in which to study drug resistance in ovarian cancer, and the presence of hormone receptors should be useful for the evaluation of hormonal therapy.
Storage Conditions
liquid nitrogen vapor temperature
Derivation
The NIH:OVCAR-3 line was established in 1982 by T.C. Hamilton, et al. from the malignant ascites of a patient with progressive adenocarcinoma of the ovary.
Yes, in nude mice inoculated subcutaneously with 10(7) cells
(Tumors developed within 21 days at 100% frequency (5/5).)
Comments
Forms colonies in soft agar and has an abnormal karyotype.
Resistant to clinically relevant concentrations of adriamycin, melphalan and cisplatin.
Both cultured cells and xenografts exhibit androgen and estrogen receptors.
Xenograft models have been used to show that treatment with 17 beta estradiol can induce progesterone receptors in this human ovarian carcinoma.
Karyotype
The cell line is aneuploid human female, with chromosome counts in the sub to near-triploid range. Several normal chromosomes (N11, N13, N14, N15, N16, N17, and N22) are clearly under-represented. Many of these missing chromosomes are represented in the large number of cytogenetically altered chromosomes identified as marker chromosomes. In addition to the marker chromosomes, there are a large number of other structurally abnormal and unassignable chromosomes that are not recognized as markers. Random loss and gain of chromosomes from cell to cell are noted in the exact chromosome counts and in the analysis of the karyotypes.
