Description

General description

MB49 cells are derived from C57BL/Icrf-a′ mouse bladder epithelial cells that were transformed by a single 24-hour treatment with the chemical carcinogen 7, 12-dimethylbenz[a]anthracene (DMBA) on the second day of a long term primary culture (1). Transformed cells transplanted into syngeneic mice were shown to generate carcinomas (1). While of male origin, karyotype analyses indicate the loss of the Y chromosome in 100% of the cells analyzed (2). This abnormality is a frequent early event in human bladder cancer.

A recent study indicates that MB49 cells recapitulate key features of sex differences in bladder tumor growth (3). MB49 implantation in mice resulted in significantly larger tumors in males than females. In the presence of dihydrotestosterone, MB49 cells exhibited enhanced proliferation in a dose-dependent manner. In contrast, MB49 cells were unresponsive to the pregnancy hormone, human chorionic gonadotrophin (hCG) (3).

MB49 cells exhibit low to no expression of MHC-Class I and II molecules (4). However, upon exposure to IFN-?, the expressions of MHC Class I and II are significantly upregulated (4).

Features and Benefits

MB49 implantation in mice resulted in significantly larger tumors in males than females. In the presence of dihydrotestosterone, MB49 cells exhibited enhanced proliferation in a dose-dependent manner. In contrast, MB49 cells were unresponsive to the pregnancy hormone human chorionic gonadotrophin (hCG) [3]. MB49 cells exhibit low to no expression of MHC-Class I and II molecules [4].
