In chronic lymphocytic leukemia (CLL), telomere dysfunction is associated with poor outcomes. TP53 is involved in cellular responses to dysfunctional telomeres, and its inactivation is the strongest adverse prognostic factor for CLL. Given the biological relationship between TP53 and telomeres, and their prognostic value, it is important to improve our understanding of the impact of TP53 altera...

TP53 is one of the most important prognostic factors in chronic lymphocytic leukemia (CLL). Modulation of microRNAs by TP53 in CLL pathogenesis has been a hotspot. Besides, it has an intimate association with other cytogenetics and plays an important part in drug resistance of CLL. All above indicate an embedded TP53-centered network in CLL pathogenesis and prognosis. In this review, we focus o...

BACKGROUND Genomic instability caused by mutation of the checkpoint molecule TP53 may endow cancer cells with the ability to undergo genomic evolution to survive stress and treatment. We attempted to gain insight into the potential contribution of ovarian cancer genomic instability resulted from TP53 mutation to the aberrant expression of multidrug resistance gene MDR1. METHODS TP53 mutation ...

BACKGROUND Survivin is an inhibitor of apoptosis and a regulator of mitotic progression. TP53 protein is a negative transcriptional regulator of survivin. The aim of our study was to evaluate the clinical significance of survivin expression in advanced stages ovarian cancer with respect to the TP53 status. METHODS Survivin and TP53 expression was evaluated immunohistochemically in 435 archiva...

The association between TP53 gene polymorphisms and breast cancer (BC) in Brazilian women is a controversial topic. In this cross-sectional study, we evaluated the association between clinical pathological variables and three polymorphisms (TP53*11, TP53*72, and TP53*248) in BC patients and controls. Genomic DNA was extracted from the blood cells of 393 participants; the cancer-free control sub...

The TP53 gene remains the most frequently altered gene in human cancer, of which variants are associated with cancer risk, therapy resistance, and poor prognosis in several tumor types. To determine the true prognostic value of TP53 variants in non-small cell lung cancer, this study conducted further research, particularly focusing on subtype and tumor stage. Therefore, we determined the TP53 s...

PURPOSE The presence of diffuse anaplasia in Wilms tumours (DAWT) is associated with TP53 mutations and poor outcome. As patients receive intensified treatment, we sought to identify whether TP53 mutational status confers additional prognostic information. PATIENTS AND METHODS We studied 40 patients with DAWT with anaplasia in the tissue from which DNA was extracted and analysed for TP53 muta...

BACKGROUND We assessed the predictive value of TP53 mutations and prostate-specific antigen (PSA) for tumor progression in prostate cancer (PCa) patients. MATERIALS AND METHODS Ninety tumor tissue samples of patients with PCa from radical prostatectomy were used. Tumor progression was estimated biochemically by the PSA level (> 0.2 microg/l) or by detection of metastases. Screening for TP53 m...
