The Prognostic Significance of TERT Locus Polymorphism (rs36115365) in Surgically Resected Non-Small Cell Lung Cancer.

Abstract:

OBJECTIVE:Telomere length is an important factor for the development of non-small cell lung cancer (NSCLC), and current articles focused on telomere associated genes. We studied the clinicopathological and prognostic implications of rs36115365 polymorphism of the TERT-CLPTM1L locus in NSCLC. The association between rs36115365 and telomere length was investigated in 176 NSCLCs. METHODS:DNA was extracted from NSCLC tissues and polymorphism and telomere length were analyzed. RESULTS:The rs36115365 polymorphism showed the following frequencies according to the genotype: G/G in 81.8% of the patients, G/C in 14.2%, and C/C in 4.0%. Average telomere length in the tumor tissues were 3.06-fold longer than telomeres in paired non-tumor tissues (SD=1.87), and telomere length was not significantly different according to rs36115365 (p=0.134). The rs36115365 polymorphism did not have any relationships with clinicopathological characteristics. A poor overall survival result was found in NSCLC with C allele carriers than that with G/G allele (p=0.034). However, disease free survival rate was not different statistically (p=0.938). CONCLUSIONS:These findings suggest that rs36115365 may contribute to the progression of NSCLC.

  • Restoration of DLC1 gene inhibits proliferation and migration of human colon cancer HT29 cells.

    abstract::DLC1 (deleted in liver cancer-1) is a new candidate tumor suppressor gene, which is inactive in various types of human cancers including colon cancer. To study the function of DLC1, we constructed a pcDNA3.1 vector containing the DLC1 gene and transfected it into HT29 colon cancer cells that were deficient in DLC1 exp...
