Abstract
The present invention relates to a process for controlling at least one androgen receptor- (AR-) regulated mechanism in mammalian cells under histone-phosphorylating conditions, said process comprising allowing at least one inhibitor with specificity for at least one protein kinase C-related kinase (PRK) to act on said at least one PRK1 thereby modulating, preferably down-regulating, the activity of said at least one PRK and optionally blocking said at least one androgen receptor-regulated mechanism in said mammalian cells.
Claims1
A method of scoring the malignancy of prostate cancer, wherein the method comprises:
- (a) determining a level of PRK1 in a sample of prostate cancer cells by using an antibody specific for PRK1;
- (b) comparing the level of PRK1 determined according to (a) with a level of PRK1 in non-cancerous prostate cells;
- and
- (c) scoring the malignancy of the prostate cancer based on the comparison of (b), a higher difference between the level of PRK1 in the prostate cancer cells and the level of PRK1 in the non-cancerous cells indicating a higher aggressiveness of the prostate cancer.
