Project description:Cancer is predominantly a somatic disease. A mutant allele found in cancer cell genome is considered somatic when it is absent in paired normal genome and dbSNP, the most comprehensive public SNP database. However, dbSNP inadequately represents several non-Caucasian populations including that from the Indian subcontinent, posing a limitation in cancer genomic analyses of data from these populations. We present TMC-SNPdb, as the first open source freely accessible (through ANNOVAR), flexible and upgradable SNP database from whole exome data of 62 normal samples derived from cancer patients of Indian origin, representing 114,309 unique germline variants. TMC-SNPdb is presented with a companion subtraction tool that can be executed with command line option or an easy-to-use graphical user interface (GUI) with the ability to deplete additional Indian population specific SNPs over and above that possible with dbSNP and 1000 Genomes databases. Using an institutional generated whole exome data set of 132 samples of Indian origin, we demonstrate that TMC-SNPdb reduced 42%, 33% and 28% false positive somatic events post dbSNP depletion in Indian origin tongue, gallbladder, and cervical cancer samples, respectively. Beyond cancer somatic analyses, we anticipate utility of TMC-SNPdb in several Mendelian germline diseases.
Project description:Kharchia local is an Indian tall landrace wheat cultivar. It is native to sodic-saline soils of Kharchia tehsil of the Pali district of Rajasthan, and is a line developed from selections from farmer's fields. It is the most salt tolerant wheat genotype found in India. No systematic study has been carried out in this direction so far. The gaps in understanding of the mechanism underlying salt tolerance limit our ability to improve the salt tolerance in other crop plants. Transcriptome analysis of Kharchia Local under salt stress will provide the insight into the genes involved in salinity tolerance.
Project description:Bites by the Indian spectacled cobra (Naja naja) are widely reported across the Indian subcontinent, with an associated high rate of mortality and morbidity. In western India (WI), the numbers of reported incidents of cobra envenomation are significantly higher than the other snake bites. In this study the venom proteome of WINn was deciphered for the first time using tandem mass spectroscopy analysis.

Project description:We genotyped 45 new samples from 4 populations of Northwest India and combined it with previously published data to characterize the population structure of modern Northwest Indian populations in the context of their geographic neighbors across South Asia and West Eurasia.
