CHK1 and p53 demonstrated a positive correlation in BUC, and both were positively associated with the histological grade, clinical pathological staging, lymphatic metastasis and the 5-year survival rate (P<0.05).
Therefore, the evaluation of EGFR and HER-2 expression in BTCC may contribute to identifying patients who are at increased risk of disease progression and recurrence.
A comparative gene set enrichment analysis of tumor and adjacent normal tissues suggested BUC tumorigenesis resulted mainly from enrichment of cell cycle and DNA damage and repair-related biological processes and pathways, including TP53 and mitotic recombination.
Deletion/duplication mutation screening of TP53 gene in patients with transitional cell carcinoma of urinary bladder using multiplex ligation-dependent probe amplification.
BAI‑1 may be involved in the negative regulation of BTCC microvascular proliferation, and its expression may be associated with a reduction in p53 mutations.
Loss of p53 and acquisition of angiogenic microRNA profile are insufficient to facilitate progression of bladder urothelial carcinoma in situ to invasive carcinoma.
MDM2 SNP309 and p53Arg72Pro polymorphisms might influence the clinical outcome of TCCB in a distinctive way between superficial TCCB and invasive TCCB.
TGF-betaRII, BAX, IGFIIR, caspase-5, hMSH3 and hMSH6 alterations are not associated with microsatellite instability or p53 mutations in invasive urothelial carcinoma of the urinary bladder.
To address to the question whether promoter methylation of novel p53 effector genes is a common event in transitional cell carcinoma of the bladder, we selected the p53 target genes apoptotic protein-activating factor (APAF-1), Caspase 8 (CASP-8), death-associated protein kinase, (DAPK-1) and insulin-like growth-factor-binding protein-3 (IGFBP-3), performing quantitative methylation-specific real-time PCR.
Protein expression and gene copy number analysis of topoisomerase 2alpha, HER2 and P53 in minimally invasive urothelial carcinoma of the urinary bladder--a multitissue array study with prognostic implications.
