Human papillomavirus (HPV) infection is a central and necessary, although not sufficient, cause of cervical cancer. Besides HPV, the additional multiple risk factors related with the onset of cervical cancer are early-age sexual activities; high number of sexual partners, which is the most salient risk factor; suppression and alteration of the immune(More)
Aberrant promoter hypermethylation of cancer associated genes occur frequently during carcinogenesis and may serve as a cancer biomarker. The aim of this study was to investigate the occurrence and relevance of promoter methylation of the tumor suppressor DAPK-1, APAF-1 () and SPARC in relation to different pathological stages and histological grades of(More)
In the present study, we have evaluated the chemopreventive potential of geraniol (GOH), an acyclic monoterpene alcohol against ferric nitrilotriacetate (Fe-NTA) induced renal oxidative stress and carcinogenesis in Wistar rats. Chronic treatment of Fe-NTA induced oxidative stress, inflammation and cellular proliferation in Wistar rats. The chemopreventive(More)
Acetaminophen (APAP) is a widely used analgesic and antipyretic drug, but at high dose it leads to undesirable side effects, such as hepatotoxicity and nephrotoxicity. The present study demonstrates the comparative hepatoprotective and nephroprotective activity of hesperidin (HD), a naturally occurring bioflavonoid against APAP induced toxicity. APAP(More)
OBJECTIVES This study evaluated the protective effects of gentisic acid (GA) against genotoxicity and hepatotoxicity induced by cyclophosphamide (CP) in Swiss albino mice. METHODS Mice were pretreated with GA orally at doses of 50 and 100 mg/kg for 14 consecutive days before the administration of a single intraperitoneal dose of 50 mg/kg CP. The(More)
UNLABELLED Abstract Objective: Doxorubicin (DXR) is an anticancer drug used in the treatment of many human malignancies. However, its clinical use is limited because of several side effects like cardiotoxicity, nephrotoxicity and hepatotoxicity. In the present study, we investigated the protective efficacy of chrysin against DXR-induced oxidative stress,(More)
The progressive increase in sporadic renal cell carcinoma (RCC) observed in industrialized countries supports the opinion that certain carcinogens present in the environment (tobacco smoke, drugs, pollutants, and dietary constituents) may affect the occurrence and progression of this disease in developing countries like India. The polymorphism of the(More)
Vitamin D exerts its activity through binding to the high-affinity nuclear vitamin D receptor (VDR), and majority of genetic studies have primarily focused on variation within this gene. Therefore, analysis of genetic variation in VDR genes may provide insight into the role of vitamin D in renal cell carcinoma (RCC) etiology in our study population. This(More)
BACKGROUND Aberrant promoter hypermethylation has been recognized in human breast carcinogenesis as a frequent molecular alteration associated with the loss of expression of a number of key regulatory genes and may serve as a biomarker. The E-cadherin gene (CDH1), mapping at chromosome 16q22, is an intercellular adhesion molecule in epithelial cells, which(More)
In this study, we investigated the association of GSTP1, GSTM1, and GSTP1 genetic variants with renal cell carcinoma (RCC) among North Indian patients. The difference in frequency of the GSTT1 null genotype between cases and control subjects was statistically significant (active ver. null, odds ratio [OR]=0.368; confidence intervals [CI] 95%=0.243-0.557,(More)
