MB49 In Vitro Reporter Gene (β-glucuronidase) Assay (CAT#: ITS-1022-YF3355)

MB49

Mouse

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. Transformed cells transplanted into syngeneic mice were shown to generate carcinomas. While of male origin, karyotype analyses indicate the loss of the Y chromosome in 100% of the cells analyzed. This abnormality is a frequent early event in human bladder cancer.

Reporter gene assays have become a valuable technique for studying gene expression by both cis- and trans-acting regulatory factors. The action of a reporter gene is evaluated in a reporter gene assay and a reporter gene construct normally comprises of a target regulatory DNA sequence (usually a major in a cancer pathway) to be analyzed, sequence for the reported gene and a sequence for functional mRNA in an expression vector. The expression vector can be transfected into the desired cell type. After transfection of the vector, the effects on a drug on the expression of target gene can be evaluated. The ideal reported gene activity should detect with high sensitivity over any endogenous gene expression. Reporter gene systems permit the use of cancer pathway-specific or developmentally regulated regulatory DNA sequences as markers to analyze gene expression in specific pathways associated with molecular mechanisms of cancer.
