Research
As more species’ genomes are sequenced,
computational analysis of these data has become increasingly
important. Our research work mainly focuses on comprehensive and
critical analysis of DNA, RNA and protein data as well as genomes
through different bioinformatics tools and techniques. We have
already initiated multidisciplinary research activities with
emphasis on basic research in frontier areas of modern biology and
high quality research on cholera and other diarrhoeal diseases. A
synopsis of our major research activities are given below.
- Cholera, the most severe and deadly diarrheal disease,
is causing pandemics since 1817. Vibrio cholerae strains,
associated with pandemics, show an unusual genomic transformation
to attain greater fitness. Thus, we are carrying out comparative
genome analysis of different Vibrio cholerae strains to
understand the evolutionary events, which influence the emergence
of their pathogenic traits. This can be a new approach to fight
against the infectious diseases like cholera.
- Antimicrobial peptides, important members of the innate
host defense system in eukaryotes, have a broad ability to kill
microbes. Beside their role as endogenous antibiotics,
antimicrobial peptides are also recorded to have roles in
inflammation, wound repair, angiogenesis and regulation of the
adaptive immune system. Thus, our objective is to detect the
evidence of positive selection of these important molecules to
undergo evolution in response to challenges by fast evolving
microbes.
- Leptospirosis has emerged to become a major public
health problem in developing countries including India. This is
the world’s most common zoonotic disease that has become an
important cause of morbidity and mortality among impoverished
populations. In the Andaman Islands of India during the early 20th
century, it occurred in the penal settlements of the British India
Administration as an acute febrile illness with hepato-renal
complications. Information regarding the disease is unavailable
from 1930 till late 1980s when Andaman haemorrhagic fever (AHF), a
mysterious illness with the majority of cases presenting with
pulmonary involvement, appeared. AHF was later identified as
leptospirosis and severe pulmonary haemorrhage was shown for the
first time as a complication of leptospirosis in India.
Leptospirosis continues to occur in the islands annually. However,
the recent availability of complete genome sequences for
Leptospira spp. has lead to important insights into the
biology of these organisms and their pathogenesis.
We are working jointly with the Regional Medical Research Centre (ICMR),
Andaman & Nicobar Islands, a WHO Collaborating Centre for
diagnosis, reference, research and training in leptospirosis, to
study the genetic difference, if any between the strains of
pathogenic, non pathogenic and intermediate phenotypic characters
and to understand the genetic changes as a repertoire of gene
acquisition and loss on an evolutionary time scale.
- Swine flu, as colloquially referred to, is a pandemic
caused by a new strain of H1N1 influenza virus in the year 2009.
The virus, as proposed by the reassortment theory, is found to
contain a combination of genes from swine, avian (bird) and human
influenza viruses. Various strains of influenza viruses have
caused pandemics since 1918. We have investigated the evolutionary
complexities of H1N1 influenza virus to explore the possible
etiology of the 2009 flu pandemic, keeping track with the earlier
recorded pandemics. We are also trying to analyze how the
evolutionary constraints have been detrimental in pronouncing the
fitness of the organism and thus the severity of the disease. We
are aiming to shed light on the evolutionary mysteries of H1N1
supported by a structural preview and thus a direct relation to
its functioning in the human host.
- Parkinson’s disease (PD) is the most common
neurodegenerative disorder characterized by lesions in numerous
regions of the brain. Our main focus has been an etiopathogenic
study of Parkinson’s disease from the aspect of disease mutations
and structural destabilization. This will help us to identify
potential role of a PD-associated gene dysfunction in pronouncing
the severity of the disease.
- Cholera Portal: A comprehensive proposal for online cholera
resource
A century of research has been conducted on cholera and its
causative organism Vibrio cholerae, yet it remains a global
health problem. The goal of this project is to develop a
comprehensive web-based cholera portal that will serve as a hub
for cholera researchers around the world. The objective is to
harness the maximum amount of information about cholera in one
place from microbiological, medical, epidemiological, ecological,
and climatic data. This will help researchers and medical
professionals working towards easing the impact of cholera,
especially during outbreak periods. The portal will be open-source
and easily accessible to the public through user-friendly search
tools. Bringing together the collective intellect of researchers
in the field will have an immense impact in advancing research in
the field and in accelerating our understanding of cholera, which
continues to pose a formidable challenge.
- ASRD (Archael Stress Response Database): The word
stress has become a very frequently encountered word in our day to
day life. Even for microscopic organisms like Archaea, there is
not much change in scenario. We are developing a comprehensive
database on Archaeal stress response genes. Such a database will
hold immense potential for further downstream works in the
relevant fields where in-depth studies of Archaeal stress
responsive proteins/genes would be required. This database is
likely to provide an instant insight, which would make the
researchers’ job faster and easier.
Training / Services
Training:
The center offers research projects to students pursuing their
post-graduation and graduation in science and engineering to meet
the partial fulfillment of their respective degrees/diplomas.
We also provide short-term training to fresh post-graduates and
graduates in science and engineering.
Workshop:
The center has already conducted several workshops in different
areas of basic and advance bioinformatics.
In the current academic year, we are also planning to arrange
workshops at regular intervals on various important domains like
Biological Knowledge Discovery, Biological Sequence Analysis,
Structural Biology, Biostatistics etc.
