Expression of RUNX3 gene in pancreatic adenocarcinoma and its clinical significance

L. - N. Xue, Bai, F. H., Wang, X. - Y., Lin, M., Tan, Y., Yao, X. - Y., and Xu, K. - Q., Expression of RUNX3 gene in pancreatic adenocarcinoma and its clinical significance, vol. 13, pp. 3940-3946, 2014.

We investigated the clinical significance of RUNX3 gene expression in human pancreatic carcinoma. Five samples of pancreatic tissues and 30 samples of pancreatic cancer tissues and paracancerous tissues were collected. RUNX3 expression was detected by real-time PCR and immunohistochemistry. The relationships between clinicopathological findings and the expression of RUNX3 were analyzed.

Influence of the c.1517G>C genetic variant in the XRCC1 gene on pancreatic cancer susceptibility in a Chinese population

Z. M. Zhao, Li, C. G., Hu, M. G., Gao, Y. X., and Liu, R., Influence of the c.1517G>C genetic variant in the XRCC1 gene on pancreatic cancer susceptibility in a Chinese population, vol. 13, pp. 4466-4472, 2014.

We investigated the influence of the c.1517G>C genetic variant in the X-ray repair complementing group 1 gene (XRCC1) on pancreatic cancer (PC) susceptibility in Chinese patients. A total of 390 PC patients and 392 controls were enrolled in this case-control study. The genotypes of c.1517G>C genetic variants were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Our findings suggested that the allele and genotype frequencies in PC patients were significantly different from those in cancer-free controls.

5-Azacytidine suppresses the proliferation of pancreatic cancer cells by inhibiting the Wnt/β-catenin signaling pathway

H. Zhang, Zhou, W. C., Li, X., Meng, W. B., Zhang, L., Zhu, X. L., Zhu, K. X., Bai, Z. T., Yan, J., Liu, T., Xu, X. C., and Li, Y. M., 5-Azacytidine suppresses the proliferation of pancreatic cancer cells by inhibiting the Wnt/β-catenin signaling pathway, vol. 13, pp. 5064-5072, 2014.

5-Azacytidine has been shown to be an effective anti-pancreatic cancer drug, but the mechanism remains unknown. In the current study, we explored the effect of 5-azacytidine on abnormal activation of the Wnt-β-catenin signaling pathway in pancreatic cancer cells. The human pancreatic cancer cell line Bxpc-3 was treated with different concentrations of 5-azacytidine for various times. The proliferation and early apoptosis of the cells were evaluated using the CCK8 method and flow cytometry, respectively.

A case-control study indicates that the TRIB1 gene is associated with pancreatic cancer

X. X. Lu, Hu, J. J., Fang, Y., Wang, Z. T., Xie, J. J., Zhan, Q., Deng, X. X., Chen, H., Jin, J. B., Peng, C. H., Liu, J., Li, H. W., and Shen, B. Y., A case-control study indicates that the TRIB1 gene is associated with pancreatic cancer, vol. 13, pp. 6142-6147, 2014.

Pancreatic cancer is a malignant neoplasm originating from transformed cells arising in tissues that form the pancreas. To investigate whether the tribbles homolog 1 (Drosophila) gene (TRIB1) is associated with pancreatic cancer in the Chinese Han population, we conducted this case-control study and genotyped 3 single nucleotide polymorphisms (rs2980879, rs2980874, and rs2235108) of the TRIB1 gene in 182 patients and 359 normal controls of Chinese Han origin and analyzed their association.

Association of c.461G>A genetic variant of OGG1 gene with pancreatic cancer susceptibility in Chinese

Z. M. Zhao, Li, C. G., Hu, M. G., Zhao, G. D., and Liu, R., Association of c.461G>A genetic variant of OGG1 gene with pancreatic cancer susceptibility in Chinese, vol. 13, pp. 7256-7261, 2014.

This study aimed to evaluate the potential association of single nucleotide polymorphisms of the 8-oxoguanine DNA glycosylase gene (OGG1) with susceptibility to pancreatic cancer (PC). A total of 764 Chinese Han subjects were recruited in this study. The polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing methods were used to detect the genotype of c.461G>A genetic variant of OGG1. The genotype and allele frequencies were statistically different in PC patients compared with cancer-free controls.
