Methods for determining chemosensitivity of cancer cells based upon expression of negative and positive signal transduction factors

摘要

Provided is a method for measuring the sensitivity of a cancer cell to an anticancer agent, which method comprises testing a sample for the mutational status, expression, and/or function of a negative signal transduction factor (NSTF), and testing the sample for the mutational status, expression, and/or function of a positive signal transduction factor (PSTF), wherein when the method comprises measuring the radiosensitivity of wild-type p53 cancer cells by testing a sample comprising wild-type p53 cells or an extract therefrom for the abundance of Raf-1 protein by Western blotting, an antibody specific to Raf-1 protein is employed.
