Research:


We ask two basic questions - Why select gangliosides are over-expressed in certain cancers ? and What's the consequence of this over-expression in relation to tumorigenesis ? To adress these, we have taken an all-round approach. Gene silencing as well as molecular cloning and over-expression strategies are 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, as well as CRISPR-Cas9 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. Very recently, data from our lab showed that the GM2-synthase gene is epigenetically regulated in renal cell carcinoma (RCC or kidney cancer) which may well extend to other cancers as well. In this recent finding, we uncovered a novel mechanism regulating the expression of this oncogene, GM2-synthase at the transcriptional level. On a different note, recent data indicate a potential role of micro RNA in GM2-mediated tumorigenesis.

POSITIONS OPEN FOR PhD STUDENTS

 

Interested Students may apply for the Projects below :

 

PROJECT 1 : Identifying the Upstream Components/Receptors involved in Ganglioside GM2-mediated Regulation of the Hippo-YAP/TAZ axis in EMT and Metastasis.

 

Brief Description - Recent reports from our laboratory have established a potential role of the tumor derived glycosphingolipid, GM2 in mediating epithelial-mesenchymal transition (EMT) leading to tumor growth and progression. Preliminary data indicates GM2-mediated inactivation of the critical tumor suppressor pathway, HIPPO and subsequent de-phosphorylation induced nuclear translocation of YAP/TAZ leading to upregulation of the YAP/TAZ-dependent genes, namely, ctgf, cyr61, lox, thbs1 etc. However, the precise signaling and the molecular mechanism leading to GM2-mediated de-activation of the HIPPO signaling is still unknown. Additionally, whether GM2-mediated HIPPO-YAP/TAZ signaling translates functionally to induce EMT and metastasis needs to be investigated. We hypothesize that GM2-dependent de-activation of HIPPO kinases, namely Mst’s and LATs might involve receptor-dependent or independent mechanisms at the cell surface, identification of which will provide an option to regulate GM2-mediated tumorigenesis.

 

Requirement - Post graduate in any discipline of Life Sciences or Biological Sciences

 

PROJECT 2 : Identifying the Role of micro RNAs in the regulation of Ganglioside GM2-mediated tumor growth, progression and metastasis.

Brief Description - This study, for the first time, focuses on the differential role of gangliosides in the regulation of microRNAs in cancer. In silico analysis of Next Generation Sequencing (NGS) data from exogenously administrated GM2 has revealed a subset of up-regulated and down-regulated miRs. A combined study of transcriptomic data as well as small RNA-seq data has identified four significantly down-regulated tumor suppressor micro RNAs (miRs). Interestingly, bioinformatics prediction, revealed that the 3ʹ-UTR of some of the genes up-regulated in response to GM2-treatment, are potential targets for at least 4 downregulated miRs. The project will primarily focus in identifying and validating these miRs and their targets in response to GM2, using classical molecular biology, biochemistry and cell biological techniques. Targeted genome editing using CRISPR-Cas9 will be used to validate the potential micro RNA targets in relation to GM2-mediated tumorigenic growth and metastasis. Additionally, analysis of the RNA seq as well as the transcriptomic data using bioinformatic tools, will be used to understand the GM2-dependent modulation of miRs and its downstream effect in tumorigenic potential. Developing prediction models for precise detection and diagnosis of cancer.

 

Requirement - Post graduate in any discipline of Life Sciences, Biological Sciences with a knowledge and keen interest in Bioinformatics, or postgraduate in Bioinformatics/related field with knowledge and keen interest to learn modern

biological wet laboratory techniques.
