To identify and characterize novel molecular targets for anti-malarial chemotherapy
Despite worldwide efforts ongoing to control and eliminate malaria, it still remains one of the deadliest parasitic infectious diseases that cause ~6.6 lakh deaths annually. Our lab works on the deadliest form of the parasite,
Plasmodium falciparum. Major factors contributing to the severity of this disease are the widespread emergence of anti-malarial drug resistance in
P. falciparum and lack of any effective vaccine. Hence, we need a deeper understanding of the basic biological processes of
Plasmodium as to understand how Plasmodium regulate its virulence and prevent the establishment of protective immunity. There is an urgent need to characterize novel molecular targets to combat the malarial infection and develop anti-malarial drugs against them. Given the essential role of epigenetics in regulation of gene expression, the goal of our research project is to identify and characterize the molecular machinery involved in bringing epigenetic changes in the parasite genome during different stages of IDC. To gain insight into these mechanisms we are applying functional genomics approaches integrating molecular biology techniques, bioinformatics, whole-genome technologies and biochemistry.
Infectious agents such as bacteria, virus or parasite when infect human host tries to alter the host genomic environment in such a manner that favours their survival and successive proliferation. An important strategy employed by these organisms to ensure their survival and replication is by epigenetic alteration of host genome to change its protein expression profile and inactivation/degradation of proteins related to cell cycle check points and apoptotic pathways.
The major objective of this study is to investigate the role of pathogens in altering the host cellular protein expression profile and its role in pathogen survival and infection. Unravelling these molecular mechanisms is important to develop strategies to prevent infection of these pathogens.
Chromatin modifiers in cancers
Aberrant gene expression and altered epigenomic modifications play an important role in tumour development and progression. The ways in which chromatin modifiers and remodelers impact wide-ranging cellular processes such as gene transcription, DNA replication and DNA damage repair, it is not surprising that their inappropriate activities may be linked to progression of diseases including cancers. Under this project, we are interested in understanding how chromatin microenvironment and chromatin modifiers regulate gene expression while maintaining a stable genome. TIP60 (a histone acetyl transferase) is known to be involved in a wide variety of vital cellular processes such as gene transcription, repair of DNA damage, autophagy etc. TIP60’s role in cancer is complex and it is found to be deregulated in various cancers. Therefore, a comprehensive understanding of normal cellular function of TIP60 as well as the aberrant functions is crucial to understand how the undesirable activities of this acetyl transferase might alter the cell proliferation program, leading to cancer.
