Project description:Total RNA was purified from keratinocytes isolated from FFPE arsenic-induced skin lesion samples collected from individuals exposed to high concentrations of arsenic exceeding 50 ppb in drinking water in Murshidibad district of West Bengal, India.
Project description:RNA from stem containing first node and internodes during dough stage was considered for the above purpose. Satabdi, (popularly known as Minikit) most popular cultivar of West Bengal and Palman, another high yielding variety were considered for microarray analysis for comparison to each other. Two rice genotypes were grown in identical conditions (same field with contaminated ground water) to obtain the most meaningful conclusion. Dough stage was considered as variation in arsenic accumulation among the genotypes starts during dough stage to maturity. Plant tissues were collected from stem for transcriptomic analysis as expression profiling of such tissue in response to arsenic would be most useful as arsenic transport/loading in grain was assumed to be controlled by arsenic translocation behavior at inter vascular level or from xylem to phloem. Satabdi accumulates more than twice of arsenic in brown rice (0.346 mg/kg) than that of Palman (0.156 mg/kg) whereas accumulation in straw (2.07 mg/kg) was approximately less than half of the Palman (4.491 mg/kg)
Project description:Russell’s viper (Daboia russelii) (RV), a category I medically important snake as well as a member of the “Big Four”, is responsible for a heavy toll of snake bite mortality and morbidity in Indian sub-continent. Epidemiological studies suggest highest incidence of RV envenomation in eastern India (EI). In this study the RV venom proteomes from Burdwan and Nadia, the two districts of West Bengal, eastern India was deciphered for the first time using tandem mass spectrometry analysis.
