An H(+)-pyrophosphatase (PPase) gene named TsVP involved in basic biochemical and physiological mechanisms was cloned from Thellungiella halophila. The deduced translation product has similar characteristics to H(+)-PPases from other species, such as Arabidopsis and rice, in terms of bioinformation. The heterologous expression of TsVP in the yeast mutant ena1 suppressed Na(+) hypersensitivity a...

Tobacco is a harmful genotoxic and mutagenic natural compound. It is genotoxic due to the chemical components contained in it like Nicotine ,phenols, benzene, carbon monoxide etc.,. Tobacco smokers are at risk of oral cancers due to the genotoxic nature of nicotine present in tobacco, which has the capacity to damage the DNA and alter its structure, finally resulting in the mutagenic and genoto...

Waterpipe Tobacco Smoke(WTS) is an unhealthy life style that may increase the risk of genotoxic responses and chronic diseases such as cancer. Micronucleus test is a successful and reliable method which is used for screening of genetotoxic responses of whole body and also for screening those people who had already exposed to genotoxic compounds. In this study, specific questionnaires were desig...
