Activating mutations of ras family genes in prostatic-cancer.


ras family genes (H-, K- and N-ras) encode for a 21 kD membrane protein which possesses GTPase activity and participates in a signal transduction pathway. Activating mutations of the ras family genes occur at codons 12, 13 and 61 and have been detected in a variety of human tumours, including colonic, bladder and pancreatic cancers. Prostatic cancer is… (More)
