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.
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:Corals in nearshore marine environments are increasingly exposed to reduced water quality, which is the major local threat to coral reefs in Hawaii. Corals surviving in such conditions may have adapted to withstand sedimentation, pollutants, and other environmental stressors. Lobe coral (Porites lobata) populations from Maunalua Bay, Hawaii showed clear genetic differentiation along with distinct cellular protein expressions between the 'polluted, high-stress' nearshore site and the 'low-stress' offshore site. To understand the driving force of the observed genetic partitioning, reciprocal transplant and common-garden experiments were conducted using the nearshore and offshore colonies of P. lobata from Maunalua Bay to assess phenotypic differences between the two coral populations. Stress-related physiological and molecular responses were compared between the two populations. Proteomic responses highlighted the inherent differences in the cellular metabolic state and activities between the two populations under the same environmental conditions; nearshore corals did not significantly alter their proteome between the sites, while offshore corals responded to the nearshore transplantation with increased abundances of proteins associated with detoxification, antioxidant, and various metabolic processes. The response differences across multiple phenotypes suggest that the observed genetic partitioning was likely due to local adaptation.
Project description:Over last decade several studies on oral cancer patients from eastern India have identified alterations in copy numbers in many regions of the chromosome such as 3p21.3, 8q24.21, 9p21, 9p22, 11q13, 11q21-24. However, all these studies employed microsatellite markers to map these CNV regions. This resulted in large map intervals (10-12 megabases) between the adjacent markers studied. As these regions contain a large number of genes, a high resolution CNV map of these regions was necessary to precisely identify novel genes affected by the amplifications and deletions. We thus used custom made Agilent 4X44K oligonucleotide array CGH platform to map the identified CNV regions in a resolution of 3 Kb in oral cancer patients from eastern India.

We thus used custom made Agilent 4X44K oligonucleotide array CGH platform to map the identified CNV regions in a resolution of 3 Kb in oral cancer patients from eastern India. Twenty-nine defined genomic intervals of ten male and two female oral cancer patients were compared with a normal male and normal female sample, respectively, by Agilent's custom oligo CGH array of 4X44K format.
Project description:The Atlantic cod (Gadus morhua L.) is one of the most important species in the Baltic Sea with high ecological and economical value. To explore the differences in adaptation to salinity between Baltic cod from different regions, western (Kiel Bight) and eastern (Gdańsk Bay) samples were analyzed through oligonucleotide microarray.
