Abstract 1214: TP53 affects SOX2 copy number alterations and expression in non-small cell lung cancer
Background: Amplifications of the transcription factor, SRY (sex determining region Y)-box 2 (SOX2), are common in non-small cell lung cancer (NSCLC). SOX2-signaling is important in maintaining the stem cell-like phenotype of cancer cells and contributes to the pathogenesis of lung cancer. TP53 is recognized as a critical regulator of stem cell pluripotency, and it is known that TP53 represses many stem cell associated genes following DNA damage. We hypothesized that SOX2 copy number alterations in lung tumors could be correlated to mutational status of TP53 gene in tumors and that TP53 played a role in regulation of SOX2 ...

Abstract 596: DKK3 expression and its function in head and neck squamous cell carcinoma
In this study, 90 cases of HNSCC tissue samples, which were obtained from Okayama University hospital with written informed consent, for immunohistochemistry to examine DKK3 protein expression. The protein expression status was scored as positive or negative. Pearson's Chi-square test and Fisher's exact test were used to evaluate the correlation between the DKK3 protein expression and clinicopathological characteristics. Kaplan-Meier analysis was performed to determine the survival analysis. For functional analyses, HNSCC-derived cells were used. Gastric and colorectal cancer cell lines were also used for comparison. DKK3 ...
