Abstract:
SNP309T>G (rs2279744) and SNP285G>C (rs117039649) in the MDM2 promoter are thought to have opposite effects on the binding of transcription factor SP1 (specificity protein 1), and consequently on MDM2 expression, p53 levels, cancer risk, age at onset, and prognosis. Here, we genotyped SNP309 and SNP285 in 406 Austrian breast cancer patients and 254 female controls. The SNP309GG genotype was associated with an increased breast cancer risk in p53 negative (OR, 1.82; 95% CI, 1.09–3.03; p = 0.02), but not p53 positive or unselected patients. In contrast, the SNP309TT genotype was associated

Abstract:
21047 Background: A single nucleotide polymorphism in the MDM2 promoter (SNP309) has been found to affect OS of advanced stage gastric adenocarcinoma (AD) and early stage squamous (SQ) cell carcinoma of the lung. The aim of this study was to evaluate the role of this polymorphism in the prognosis of esophageal cancer, another aerodigestive cancer. Methods: 150 early stage (E) and 118 locally advanced stage (LA) esophageal cancers were genotyped for MDM2 SNP309 using Taqman. The primary endpoint was overall survival (OS). Results: E disease: n=23 stage I; n=127 stage II. LA disease: n=93, Stage

Purpose A single nucleotide polymorphism (SNP) at position 309 in the promoter region of MDM2 leading to increased expression of MDM2 and attenuated function of p53 has been negatively associated with onset and outcome of disease in solid tumors. Because inactivation of p53 by deletion and/or mutations also impacts on the clinical course of B-cell chronic lymphocytic leukemia (B-CLL), we assessed the role of the SNP309 genotype in B-CLL.

Because inactivation of p53 by deletion and/or mutations also impacts on the clinical course of CLL, we assessed the role of the SNP309 genotype in CLL among Chinese populations.

Abstract Abstract 3888 In B-CLL, mutations in the IGHV genes encoding the BCR are correlated with disease aggressiveness: patients with unmutated BCR (U-CLL) typically have a worse prognosis than those with mutated BCR (M-CLL). Evidence that many U-CLL express BCR with specificity toward apoptotic cell antigens suggests that dying cells provide pro-survival signals for U-CLL clones. Thus progression of U-CLL may depend both on mechanisms that ensure the clone's survival and those that promote cell death.

Purpose Adequate biomarkers are still required to optimize therapy in patients with locally advanced head and neck squamous carcinomas (HNSCC) treated with chemoradiotherapy (CRT). Methods We updated the follow-up of 66 HNSCC patients treated with CRT we described more than 10 years ago, focusing on SNP Arg/Pro (R/P) at codon 72 and somatic mutations in TP53 and on SNP309 in the MDM2 gene. Results In wild-type TP53 cases, overall survival (OS) was longer in 72RR and less favorable in 72PP (p = 0.005); when TP53 was mutated, OS was longest in 72PP and less favorable in 72RR and 72RP (p = 0.058)

Abstract:
10550 Background: MDM2 protein is a key negative regulator of p53 protein by targeting its destruction through the ubiquitin pathway. A single nucleotide polymorphism (SNP309 T→G) has been identified in the promoter of the MDM2 gene which results in higher levels of MDM2 protein, attenuation of the p53 pathway, and enhanced tumorigenesis. Estrogen signaling has also been shown to upregulate MDM2 expression. Recent studies have suggested that the MDM2 SNP309 polymorphism is associated with earlier age of onset of certain cancers, particularly in women. The purpose of this study was to determine

Abstract:
The presence of TP53 mutations has been associated with inferior outcome in diffuse large B-cell lymphoma (DLBCL) and chronic lymphocytic leukemia (CLL). In DLBCL, the impact of the TP53 codon 72 polymorphism and MDM2 SNP309 has not been clearly elucidated, whereas MDM2 SNP309 was suggested as a poor-prognostic marker in CLL. In addition, p16INK4a promoter hypermethylation has been implicated as a negative prognostic factor in DLBCL. The aim of this thesis was to further evaluate these molecular markers in well-characterised materials of DLBCL and CLL. In paper I, we investigated the prognosti
