PLEKHS1: A new molecular marker predicting risk of progression of non-muscle-invasive bladder cancer.

ABSTRACT: Promoter mutations of pleckstrin homology domain-containing S1 (PLEKHS1) are frequent in several cancer types. To evaluate the DNA mutations, the mRNA expression and prognostic value of PLEKHS1 was evaluated in bladder cancer. We investigated DNA mutations and mRNA expression of PLEKHS1 in a first series of 154 bladder tumors [71 non-muscle-invasive bladder cancer (NMIBC) and 83 muscle-invasive bladder cancers (MIBC)] from patients who underwent transurethral bladder resection or radical cystectomy between 2001 and 2006, and 20 normal bladder samples. Results were then validated in a second series of 181 bladder tumors (91 NMIBC and 90 MIBC). All patients have signed an informed consent form. DNA mutations were analysed by high-resolution melt analysis and sanger seque
