OBJECTIVE A sensitive mutation detection method called co-amplification at lower denaturation temperature-polymerase chain reaction (COLD-PCR) was applied to improve the detection frequencies of expressive mutations in the H-ras gene, including exons 1 and 2, in a group of Chinese patients diagnosed with bladder cancer. MATERIALS AND METHODS The(More)
OBJECTIVE To investigate the clinical significance of cadherin 13 (CDH13) gene promoter methylation in the serum of patients with prostate cancer. METHODS This prospective study examined the methylation status of CDH13 in serum samples obtained from patients with primary prostate cancer and age-matched control subjects, using methylation-specific(More)
BACKGROUND Prostate cancer is a common malignancy in men, and inevitably some patients experience biochemical recurrence after radical prostatectomy. To date, there are no reliable predictors for prostate cancer recurrence, and novel predictors are urgently needed. PCDH10 (protocadherin-10) is a novel tumor suppressor gene, which is down-regulated by(More)
BACKGROUND Aberrant methylation of protocadherin 17 (PCDH17) has been reported in several human cancers. However, the methylation status of PCDH17 in prostate cancer and its clinical significance remains unclear. The aim of this study was to investigate the methylation status of PCDH17 and its clinical significance in patients with prostate cancer after(More)
BACKGROUND Protocadherin8 has been demonstrated to play critical roles in initiation and progression of several human cancers. It is frequently inactivated by promoter methylation in cancers and may be used as a potential biomarker. However, the methylation status of protocadherin8 and its clinical significance in prostate cancer remains largely unknown.(More)
OBJECTIVE To investigate the clinical significance of protocadherin-8 (PCDH8) promoter methylation in bladder cancer. METHODS Methylation-specific polymerase chain reaction was used to examine the promoter methylation status of PCDH8 in tumour tissue samples obtained from patients with bladder cancer, and in normal bladder epithelial tissue samples(More)
BACKGROUND CDH13 is a novel tumor suppressor gene often inactivated by aberrant promoter methylation in human cancers. Previous studies have shown that CDH13 methylation correlated with advanced disease and poor prognosis in non-muscle invasive bladder cancer (NMIBC). The aim of the current study was to investigate the correlations between CDH13 methylation(More)
BACKGROUND PCDH8 is a novel tumor suppressor gene, and frequently inactivated by promoter methylation in human cancers. However, there is little information regarding PCDH8 methylation in non-muscle invasive bladder cancer (NMIBC). The aim of this study was to investigate the methylation status of PCDH8 in NMIBC and its clinical significance. METHODS The(More)
OBJECTIVE To investigate the clinical significance of protocadherin 17 (PCDH17) promoter methylation in bladder cancer. METHODS Methylation-specific polymerase chain reaction was used to examine the promoter methylation status of PCDH17 in tumour tissue specimens obtained from patients with bladder cancer, and in normal bladder epithelial tissue specimens(More)
OBJECTIVES H-cadherin, functions as a tumor suppressor, is frequently silenced by promoter methylation in human cancers. The aim of this study was to evaluate the feasibility of using H-cadherin methylation in tumor tissues as a potential biomarker in patients with bladder transitional cell carcinoma (TCC). MATERIALS AND METHODS We examined the(More)
