Etiology of cervical cancer is associated with excessive inflammation mediated tumorigenesis. Pro and anti-inflammatory cytokines (tumor necrosis factor alpha, TNFA and interleukin, IL-10) are involved in fighting against the tumorigenesis. Therefore, the present study was designed to evaluate the association of TNFA (-308G>A) and IL-10 (-819C>T) gene polymorphism with risk of cervical cancer. One hundred fifty histopathologically confirmed patients with cervical cancer and 162 age, ethnically-matched cervical cytology negative healthy controls were genotyped for TNFA (-308 G>A) and IL-10 (-819 C>T) polymorphisms using PCR-RFLP. Individuals with combination of TNFA -308GA+AA genotype and A allele were at elevated risk of cervical cancer (odds ratio (OR) = 2.24; P = 0.018 and OR, 2.05; P = 0.012). Frequency of IL-10 -819CT+TT genotype combination and T allele was slightly higher in cases as compared with controls but difference was not significant (OR = 1.52; P = 0.069 and OR = 1.38; P = 0.051). In association of genotypes with clinical characteristics, presence of TNFA -308GA+AA genotype conferred high risk for the stages (IB) (OR = 2.86, P = 0.039) and stages (III) (OR = 2.52; P = 0.015) of cervical cancer. In contrast, IL-10 -819TT genotype was not associated with higher risk of clinical characteristics of cervical cancer. In conclusion, individuals with TNFA -308*A allele carriers were at significantly higher risk of cervical cancer particularly early (IB) and advanced stages (III). However, IL-10 (-819C>T) polymorphism was not associated with risk of cervical cancer.
Most polyphenols can cross blood-brain barrier, therefore, they are widely utilized in the treatment of various neurodegenerative diseases (ND). Resveratrol, a natural polyphenol contained in blueberry, grapes, mulberry, etc., is well documented to exhibit potent neuroprotective activity against different ND by mitochondria modulation approach. Mitochondrial function impairment is the most common etiology and pathological process in various neurodegenerative disorders, viz. Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and amyotrophic lateral sclerosis. Nowadays these ND associated with mitochondrial dysfunction have become a major threat to public health as well as health care systems in terms of financial burden. Currently available therapies for ND are limited to symptomatic cures and have inevitable toxic effects. Therefore, there is a strict requirement for a safe and highly effective drug treatment developed from natural compounds. The current review provides updated information about the potential of resveratrol to target mitochondria in the treatment of ND.
Inflammation plays a major role in the pathogenesis of cervical cancer. Chemokines are involved in inflammation, cancer, and infectious diseases. Therefore, we evaluated the association of the chemokine receptor gene polymorphism CCR5 Delta32 with risk of cervical cancer. A total of 150 histopathologically confirmed patients with cervical cancer and 162 age and ethnically matched cervical cytology negative healthy controls were genotyped for CCR5 Delta32 polymorphisms using PCR. Association of CCR5 Delta32 genotypes with risk of cervical cancer, clinical stages, and tobacco exposure was analyzed using chi-square statistical tests. The frequency of the mutant allele CCR5 Delta32 was higher in patients with cervical carcinoma (2.3%) but there was no statistically significant difference (OR = 1.51; p = 0.685;). Association of CCR5 genotypes with clinical phenotypes showed significant risk with stage IB patients due to CCR5+/Delta32 genotype (OR = 4.43; p = 0.021). Furthermore, patients with CCR5+/Delta32 genotype and tobacco usage were at risk of cervical cancer (OR = 1.73, 95% CI = 0.27-1.28). In summary, CCR5 heterozygous genotype (+/Delta32) may significantly influence the early stage of cervical cancer development. However, the cervical cancer risk due to tobacco usage was not significantly modulated after interaction with CCR5+/Delta32 genotype.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
