Soil microorganisms and biogeochemical cycles in a grazing ecosystem: interactions between producers, consumers, and decomposers
Microorganisms are the unseen majority that determines ecosystem processes, they perform biogeochemical functions that translate into essential services, and regulate global climate. In grazing ecosystems, which represent ... -
Biogeography and comparative phylogeography of freshwater snails of India
Distribution of flora and fauna is shaped by both current and historical processes. In my thesis I concentrated on how the historical component of the governing processes have dictated the current distribution of biota. ... -
Design of soluble and particulate immunogens derived from the stem of Influenza hemagglutinin
Influenza is a highly contagious virus, belonging to the family Orthomyxoviridae that causes acute febrile respiratory illness which can be fatal in some cases. The highest risk groups for influenza viral infection ... -
Deciphering the evolutionary significance of maintaining cryptic genetic systems by bacteria
Cryptic genes are phenotypically silent DNA sequences with the potential to code for a function, but remain inactive during the normal life span of the organism. However they can be activated by a single mutational event ... -
Use of sub-family specific residues of protein modules in recognizing sites of functional and structural specialization
Functional and regulatory features of a protein in a living system are determined by several factors such as chemical nature and three-dimensional arrangement of residues in the functional site, spatial and temporal ... -
Molecular basis of attenuation of the live attenuated Japanese encephalitis virus vaccine SA14-14-2
Japanese encephalitis virus is a member of Flaviviridae family. Flaviviridae family has four genera which comprises of Flavivirus, Pestivirus, Hepacivirus and Pegivirus. The global burden of disease caused by these viruses ... -
A place for everything and everything in its place: Spatial organization of wasps on the nests of the primitively eusocial paper wasp Ropalidia marginata
In my thesis, I found that queens and workers in the primitively eusocial paper wasp Ropalidia marginata use space on their nests non-randomly with a majority of individuals showing spatial fidelity to small core areas, ... -
Integration of sequences, structures, dynamics to study functional divergence in homologous proteins and their assemblies
Functions of proteins are governed by their sequences, structures, dynamics and assembly. Modulation of these factors during evolution renders functional divergence in related proteins that have originated from the common ... -
Stereochemical studies on peptide and protein structures: Implications for validation, flexibility, and dynamics
Accuracy of 3-D structures of proteins is crucial, both in terms of its agreement with the experimental data used to determine the structure and stereochemistry, especially when they are utilized for applications like drug ... -
Regulation of Lateral Mobility of Amyloid Precursor Protein by an Alzheimer’s Disease Risk Gene: Picalm
Amyloid Precursor Protein (APP) is implicated in several functions in neurons, but the altered processing of APP in synapses holds a key to understanding the onset of the molecular progression of Alzheimer’s Disease (AD). ... -
Understanding the structural organization of the carrier translocase machinery in regulating mitochondrial biogenesis and organelle quality control
Mitochondria are essential eukaryotic organelles required for diverse cellular functions including, energy homeostasis, iron-sulfur cluster biogenesis, and signaling. Therefore, the maintenance of organelle quality control ... -
Diversity from the Gut to Species: Phylogeny, Population genetics and Microbiome of the Antilope cervicapra
Evolutionary relationships between members of the Antilopina taxon have been much debated in recent years. The ‘true antelope’ clade is currently comprised of 4 genera viz., Gazella, Nanger, Eudorcas and the monotypic genus ... -
Investigating Partners of OsMADS1 Transcription Factor and functions for some associated factors for roles in rice inflorescence and floral development
Title: Investigating Partners of OsMADS1 Transcription Factor and functions for some associated factors for roles in rice inflorescence and floral development The classic ABCDE model for floral organ identity show that ... -
Single-channel studies on human TREK-1 (hTREK-1) channels to intracellular ischemia related factors
TREK-1, a member of the two-pore domain family of potassium channels, majorly contributes to the maintenance of resting membrane potential of a cell and has been reported to respond to ischemic levels of intracellular ... -
Host responses in Fas-deficient autoimmune-prone lpr mice upon Salmonella Typhimurium infection
Autoimmune diseases can potentially pre-dispose an individual to infections. On the other hand, infections can trigger, exacerbate or ameliorate autoimmunity. Autoimmune Lymphoproliferative Syndrome (ALPS) is a rare genetic ... -
Determination of significance of SUMOylation of the Smc5/6 complex
The fascination of scientists to the Smc5/6 complex began in the 1990s, with the characterization of UV and γ radiation-sensitive rad18 mutant and its identification as a component of a novel Structural Maintenance of ... -
Suppression of epileptiform activity by lactate through HCA1 and GIRK channel activation in rat subicular pyramidal neurons
In the present study, we report a lactate-induced hyperpolarization and reduction of epileptiform activity in subicular weak burst firing and regular firing neurons using patch clamp electrophysiology. We showed the ... -
Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ... -
Role of Glycosylation and Oligomerization on the Stability of Soybean Agglutinin
Carbohydrates are vital to life. In their naive form, they serve as a primary energy source for supporting life. However, in most cases carbohydrates do not exist as simple sugars in nature. Instead they occur as more ... -
Post-transcriptional regulation of the tumor suppressor gene TSC1 and its relevance in Oral Squamous Cell Carcinoma
Oral cancer or oral squamous cell carcinoma (OSCC) is a subset of head and neck cancer (excluding non-melanoma skin cancer), with an estimated 354,864 new cases and 177,384 deaths reported annually. India accounts for 34% ...
