Oral cancer is the leading cancer type among Southeast Asian men and is causally associated with the use of tobacco. Genetic polymorphisms in xenobiotic-metabolizing enzymes modify the effect of environmental exposures, thereby playing a significant role in gene-environment interactions and hence
BACKGROUND
Loss of heterozygosity (LOH) at tumor suppressor genes, such as adenomatous polyposis coli (APC) and mutated in colon cancer (MCC) genes, is one of the early events in carcinogenesis of oral tissue in Caucasian and Chinese patients. We wanted to check whether it is also true in Indian
Polymorphism in glutathione S-transferase (GST) genes, causing variations in enzyme activities, may influence susceptibility to oral cancer and leukoplakia in smokers and/or smokeless tobacco users. In this case-control study consisting of 109 leukoplakia and 256 oral cancer patients and 259
In a house-to-house survey, 36 471 tobacco chewers and smokers were selected from the rural population in three areas of India. These individuals were interviewed for their tobacco habits and examined for the presence of oral leukoplakia and other precancerous lesions, first in a baseline survey,
Multidrug resistance (MDR) can limit efficacy of chemotherapy. The best studied mechanism involves P-gp (P-glycoprotein) mediated drug efflux. This study focuses on MDR reversal agents from medicinal plants, which can interfere with P-gp. Rhodamine 123 accumulation assay and flow cytometry analysis
BACKGROUND
Oral cancer is one of the five leading sites of cancer in the Indian population. In the present study we analyzed the expression of apoptosis regulating genes, viz. survivin, Bcl-2, Bax and p53 in precancerous and cancerous lesions of the buccal mucosa of Indian tobacco
This study evaluates the influence of genetic polymorphism at GSTM1, GSTM3 and GSTT1 gene loci on oral cancer risk among Indians habituated to the use of, smokeless tobacco, bidi or cigarette. DNA extracted from white blood cells of 297 cancer patients and 450 healthy controls by the proteinase K
BACKGROUND
Oral cancer is the sixth most common malignancy in the world. Viruses are the causative agents of approximately 10-15% of all cancers worldwide (Cancers, 6, 2014 and 2155). The tumorigenic roles of Epstein-Barr virus in oral cancer are unclear. Literature search results are conflicting
The mutagenic potential of aqueous extracts of masheri (ME), chewing tobacco alone (CTE) and a mixture of chewing tobacco plus lime (CTLE) was tested using the Ames assay. ME exhibited mutagenicity in Salmonella typhimurium TA98 upon metabolic activation with aroclor-1254-induced rat liver S9, while
Chewing Chewable Indian Tobacco (CIT) is a popular addiction in India. Some of the addicts keep the bolus of chewed tobacco tucked in the gingivo-labial sulcus (cheek pouch) overnight. This is known as the habit of the night quid. To assess the influence of night quid on the development of oral
BACKGROUND
Asian Indians (AIs) in the United States exhibit disproportionate burdens of oral cancer and cardiovascular disease, which are potentially linked to smokeless tobacco. However, little is known about the use of cultural smokeless tobacco (CST) products in this
There are insufficient safe and effective treatments for chronic pain in pets. In cases such as osteoarthritis there is no commercially available cure and veterinarians use NSAIDs to manage pain. Pet owners may have to plan for a lifetime of plant-based treatment for the conditions
