DNA methyltransferase 3B -149C/T polymorphism and the risk of laryngeal squamous cell carcinoma: a case-control study

X. M. Zhang, Li, S., and Zhang, Q. M., DNA methyltransferase 3B -149C/T polymorphism and the risk of laryngeal squamous cell carcinoma: a case-control study, vol. 14, pp. 12866-12871, 2015.

A variety of molecular epidemiological studies have been conducted to examine the association between the DNMT3B -149C/T polymorphism and cancer susceptibility; however, there has been no study investigating the association between the DNMT3B -149C/T polymorphism and the risk of laryngeal squamous cell carcinoma (LSCC) until now. To determine the role of the DNMT3B -149C/T polymorphism in LSCC, we genotyped 113 patients with LSCC and 110 controls from a Chinese population using polymerase chain reaction-restriction fragment length polymorphism analysis.

Association between HLA-C*04 and American cutaneous leishmaniasis in endemic region of southern Brazil

R. C. Ribas-Silva, Ribas, A. D., Ferreira, E. C., Silveira, T. G. V., and Borelli, S. D., Association between HLA-C*04 and American cutaneous leishmaniasis in endemic region of southern Brazil, vol. 14, pp. 14929-14935, 2015.

Leishmaniasis is a parasitic infectious disease with global repercussions. American cutaneous leishmaniasis (ACL) is endemic in southern Brazil and its pathogenesis varies according to parasite species, immune response, and host genetics. In terms of immunogenetics, many host genes, including HLA (human leukocyte antigen), could be involved in susceptibility to and protection against ACL. Accordingly, the aim of this study was to investigate the association between HLA class I genes (HLA-A, -B, and -C) and ACL in an endemic region of southern Brazil.

Effect of CYP1A1 and GSTM1 genetic polymorphisms on bone tumor susceptibility

L. Li, Li, J. G., Liu, C. Y., and Ding, Y. J., Effect of CYP1A1 and GSTM1 genetic polymorphisms on bone tumor susceptibility, vol. 14, pp. 16600-16607, 2015.

Tumor gene polymorphisms are often associated with individual susceptibility to genetic diseases. Cytochrome P4501A1 (CYP1A1) and glutathione S-transferase mu 1 (GSTM1) gene polymorphisms are closely related to the susceptibility of the body to chemical carcinogens in the environment. Therefore, we explored the relationship between CYP1A1 and GSTM1 gene polymorphisms and susceptibility to bone tumors.

Association between the rs4753426 polymorphism in MTNR1B with fasting plasma glucose level and pancreatic β-cell function in gestational diabetes mellitus

Y. Zhan, Li, C., Gao, Q., Chen, J., Yu, S., and Liu, S. G., Association between the rs4753426 polymorphism in MTNR1B with fasting plasma glucose level and pancreatic β-cell function in gestational diabetes mellitus, vol. 14, pp. 8778-8785, 2015.

We investigated the association between rs4753426 single nucleotide polymorphisms in the melatonin receptor 1B (MTNR1B) gene and the risk of developing gestational diabetes mellitus (GDM). A total of 516 gravidas (186 with GDM and 330 non-diabetic controls) were enrolled in the study. Genotype and allele frequencies of rs4753426 in the MTNR1B gene were detected by DNA sequencing. Fasting plasma glucose and fasting insulin levels were measured to calculate the homeostasis model assessment for insulin resistance (HOMA-IR) and for β-cell function.
