We have taken an all round approach towards understanding the basis of aberrant ganglioside expression in various tumors as well as studying the consequence of such an abnormal expression in carcinogenesis. Gene silencing as well as molecular cloning and over-expression strategies have been utilized to establish the potential role of tumor derived glycosphingolipids in migration as well as invasion of tumor cells. Gene expression profiling suggests a large number of differentially regulated gene sets (DRGs) in response to GM2-synthase knockdown and mechanistic studies reveal a critical role of the integrin signaling pathway to be involved in GM2 mediated tumor cell migration. With an aim to translate these in vitro findings in vivo, targeted genome editing technology by TALEN is used to define the functional role of GM2 in tumorigenesis. Studies indicate that GM2 is involved in epithelial-mesenchymal transition (EMT) by promoting anoikis resistance in tumors. Studies are under way to elucidate the mechanism of GM2 mediated EMT. Finally, we have initiated a study to find out the basis of over-expression of several ganglioside synthase genes in cancer, currently focusing on the regulation of GM2-synthase gene. Preliminary data suggests that there may be a plausible epigenetic role in the regulation of GM2-synthase gene in cancer. On a different note, we have very recently undertaken a collaborative study, to screen and identify potential anti-inflammatory compounds from natural sources, those by virtue of being anti-inflammatory may be able to protect against chronic inflammation induced disease pathogenesis, like cancer.
