Current Research Interest:

The main aim of our laboratory is to understand the mystery of glycosylation of biomolecules with special emphasis on the role of sialoglycoconjugates in different disease models and its potential applications in disease management, its specificity and recognition in immune responses mainly in the field of cancer biology/tumor immunology and host-pathogen interactions dealing with visceral leishmaniasis (VL) and Pseudomonas aeruginosa (PA). We have analyzed childhood acute lymphoblastic leukemia (ALL), VL and PA-associated biomolecules by exploring the diversity of sialylation with a common set of questions through proteomic and glycobiological aspects.

Additionally, another important goal of our laboratory is to deliver low cost affordable healthcare to all using India’s vast resources of medicinal plants. Currently we had put lots of effort towards chemotherapeutic advancement in cancer since 2008. My group has identified a non-toxic herbal molecule alone/or extract/or in-combination with existing-known drugs showing great potential against an array of cancer cell lines/ cancer stem cells both in vitro and in vivo and even in hypoxic condition.

Our activities are broadly divided as follows described below:

 Proteomic, glycomic and glycoimmunological work on sialylated glycoconjugates induced on lymphoblasts and their modulation mainly in childhood acute lymphoblastic leukemia (ALL) and other cancers

 Define cancer cells by glycoenzymology (glycosylation regulating enzymes) and establish the early response disease specific enzymes as diagnostic markers

 Identification of anti-cancer lead herbal molecules based on edible nontoxic medicinal plants and potential targets through signalling cross talks and through Systems Biology approaches

Role of glycosylations/unique sialylation on host immune cells and parasite specific biomolecules in visceral leishmaniasis (VL) and their immunological role in host-pathogen interaction



Proteomic/glycomic approach on host and pathogen specific biomolecules to address innate immune response for survival of Pseudomonas aeruginosa in hostile environment of host
