PURPOSE A common polymorphism of the tumor suppressor gene TP53 at codon 72 has been associated with human cancer susceptibility and prognosis. To examine the role of the polymorphism in the gastric adenocarcinoma, we examined 397 patients with or without the cancer. EXPERIMENTAL DESIGN DNA samples were extracted from archived gastric tumor tissues and/or normal tissues of gastric adenocarcin...
Human TP53 gene is characterised by a polymorphism at codon 72 leading to an Arginine-to-Proline (R/P) substitution. The two resulting p53 isoforms have a different subcellular localisation after stress (more nuclear or more mitochondrial for the P or R isoform, respectively). p53P72 variant is more efficient than p53R72 in inducing the expression of genes involved in nuclear DNA repair. Since ...
UNLABELLED The tumor-suppressor protein p53, encoded by TP53, inhibits tumorigenesis by inducing cell-cycle arrest, senescence, and apoptosis. Several genetic polymorphisms exist in TP53, including a proline to arginine variant at amino acid 72 (P72 and R72, respectively); this polymorphism alters p53 function. In general, the P72 variant shows increased ability to induce cell-cycle arrest, whe...
PURPOSE To examine the clinical utility of intratumor microRNAs (miRNA) as a biomarker for predicting responses to platinum-based doublet chemotherapy in patients with recurring lung adenocarcinoma (LADC). EXPERIMENTAL DESIGN The expression of miRNAs was examined in LADC tissues surgically resected from patients treated with platinum-based doublet chemotherapy at the time of LADC recurrence. ...
