Detecting homozygous deletions in the CDKN2A(p16(INK4a))/ARF(p14(ARF)) gene in urinary bladder cancer using real-time quantitative PCR.

Abstract

We have established a fast and efficient method for detection of HDs. Our data support the notion that inactivation, including HDs, of CDKN2A/ARF is an early event in transitional cell carcinoma. We observed separate and specific targeting of the CDKN2A and ARF genes, respectively, and that simultaneous inactivation of ARF and p53 occurs.
