Association of interleukin-6 genetic polymorphisms with risk of OSCC in Indian population

چکیده
PURPOSE Interleukin-6 (IL-6) encodes a cytokine protein, which causes inflammation, maintains immune homeostasis and plays an essential role in oral pathogenesis. The aim of this study was to evaluate the association between IL-6 (- 174 and - 572) G/C promoter gene polymorphisms and risk of OSCC among Indians. METHODS Single nucleotide polymorphism in IL-6 genes was genotyped in OSCC patients and healthy controls by PCR-RFLP method. Genotype and allele frequencies were analyzed by chi-square test and strength of associations by odds ratio with 95% confidence intervals. RESULTS Frequency distribution of IL-6 (- 174) G/C gene polymorphism was significantly associated with OSCC patients in comparison to healthy controls (OR: 0.541, CI: 0.356-0.822; p: 0.004. However, frequency of IL-6 (- 572) G/C gene polymorphism was not significantly associated with OSCC patients (p > 0.05). CONCLUSION The genotype GC and allele C of IL-6 (- 174) G/C gene polymorphism play a significant role in OSCC susceptibility.

Association between IL6 gene polymorphism and the risk of chronic obstructive pulmonary disease in the north Indian population
Interleukin-6 (IL6) is encoded by the IL6 gene in human and acts as pro-inflammatory cytokine and an anti-inflammatory cytokine. Recent studies established that IL6 substantially contribute in the diagnosed of systemic inflammation for the patients suffering from lung diseases such as chronic obstructive pulmonary disease (COPD). Thereof, this work aimed to investigate the prot...

Role of EGFR Gene Polymorphisms in Oral Squamous Cell Carcinoma patients of Southeast of Iran: A Case-Control Study
Background: The decisive etiology of Oral squamous cell carcinoma (OSCC) is still ambiguous, but we recognize the contribution of genetic aberration and environmental agent due to OSCC initiation. In the current study, we elucidate the potential impact of EGFR gene polymorphisms in the risk of OSCC in the southeast of Iran. Methods: Forty-eight OSCC patients along with 100 normal volunteers w...
