Genetic and environmental determinants of swarming in Pseudomonas aeruginosa
Swarming, in bacteria, is a type of group translocation phenomenon observed in several flagellated species characterized by their ability to spread across solid or semi-solid surfaces rapidly – often with a distinct colony ... -
In vivo mechanistic insights into the trans-splicing based expression of Hsp90 in Giardia lamblia
Giardia lamblia, a simple yet intriguing protozoan parasite, challenges conventional paradigms in gene expression through its unique mechanism of trans-splicing for Heat Shock Protein 90 (Hsp90). As a primitive organism, ... -
Insights into life-cycle stage transition of Trichomonas vaginalis and advancement in its diagnosis
Trichomonas vaginalis is a protozoan parasite and the causative agent of the most common non-viral, sexually transmitted disease (STD) in humans known as trichomoniasis. WHO estimates more than 270 million cases of ... -
Investigating mechanisms underlying astrocytic involvement in depressive-like behavior and antidepressant action
Major Depressive disorder (MDD) is a complex, multifactorial psychiatric illness which affects over 20% of the population worldwide. Despite its prevalence, our understanding of its pathophysiology is severely limited, ... -
Investigating the role of an atypical dual-specificity phosphatase DUSP28 in mammalian cells
Dual-specificity phosphatases (DUSPs) belong to the protein tyrosine phosphatases (PTP) subfamily and dephosphorylate, both serine/threonine and tyrosine residues of proteins and non-protein substrates. A subgroup of ... -
Investigating the role of miR-198 in oral squamous cell carcinoma pathogenesis
Evidence supports the critical role of microRNA (miRNA) dysregulation in several diseases including cancers. The aberrant expression of numerous tumor suppressor and oncogenic miRNAs is a well-established driving factor ... -
Isolation, structure elucidation and increasing anticancer efficacy of an anti-cancer secondary metabolite from a marine-derived endophytic fungus, Aspergillus species
Cancer is the leading cause of mortality globally, contributing to ~10 million fatalities in 2020, or roughly one in every six deaths, according to global cancer statistics 2020. Around 50% of all small molecules approved ... -
A Ligase IV/XRCC4-dependent single strand break repair pathway for the maintenance of A/T-rich regions during DNA replication in mammals
The DNA in our cells is under constant threat from various exogenous and endogenous sources. To ensure error free and faithful transmission of hereditary material, human cells employ several DNA repair pathways. Mammalian ... -
Metabolic and Pharmacological Modulations During IFN-γ signaling
Interferons, initially discovered for their antiviral properties, play pivotal roles in various biological processes, including host defense against pathogens, tumor surveillance, and disease pathogenesis. Interferon-gamma ... -
miRNA-based regulation of Coxsackievirus B3 replication and pathogenesis
Coxsackievirus B3 (CVB3) is a single-stranded, positive-sense RNA virus known to cause acute myocarditis, pancreatitis, and aseptic meningitis. In many cases, the long-term impact of CVB3 infection-induced cell death ... -
Molecular pathways governing maturation and decay of precursor piRNAs in Caenorhabditis elegans
Piwi-interacting RNAs (piRNAs) are an animal-specific class of germline-enriched small non-coding RNAs that play a crucial role in germline development and fertility in diverse organisms. In Caenorhabditis elegans (C. ... -
Neuronal complex bursts and network information transfer in the hippocampus are robust to biophysical heterogeneities
Biological entities must adopt mechanisms to override the impact of external perturbations to achieve stability and robustness. A crucial feature of biological systems is that they exhibit several forms of heterogeneities ... -
Non-canonical functions of lymphoid-specific proteins AID and RAG1: Understanding mechanism, regulation, and implications in genomic instability
Recombination-activating genes (RAGs) and Activation-induced cytidine deaminase (AID) are lymphoid cell-specific proteins that play crucial roles in the development of adaptive immunity. Diversification of the immune system ... -
The Nse1p RING domain is required for maintaining transcriptional silencing and genomic organization in Saccharomyces cerevisiae
Chromatin is a dynamic structure that reorganizes to support proper transcription, replication, repair, and segregation. Principal chromosomal constituents that shape chromosomes are the SMC (Structural Maintenance of ... -
Peritoneal colonization of ovarian cancer
The primary cause of mortality associated with cancer is metastasis, i.e., the spread of transformed cells from the site of oncogenesis to secondary loci within the body. Epithelial ovarian cancer (EOC) is a debilitating ... -
Qualitative similarities and differences between monkey and human visual perception
Animal models play a crucial role in helping neuroscientists unravel the computations supporting behaviour at the resolution of a single neuron in the brain. In vision science, the macaque monkey is the pre-eminent model ... -
Rice transcription factors OsMADS2 and OsMADS4 regulate floret organ development: Deciphering their gene targets, traits and functions related to their unequal genetic redundancy
Organs in modern dicot flowers are positioned in concentric rings (whorls). The outermost whorl has green protective sepals, internal to which are showy petals, and the reproductive stamen and carpel whorls. Florets of ... -
Role of 3D-organization of the X-inactivation centre in imprinted X-chromosome inactivation
The connection between 3D-genome organization and genome regulation is one of the fundamental questions in modern biology. In a nucleus, the genome is organized through different layers of 3D-organization such as ... -
Role of autophagy in reducing peripheral neuropathy and diabetic peripheral neuropathy
Peripheral neuropathy occurs when there is damage to the central or peripheral nervous system due to injury, disease, diabetes, or drug use. Endoplasmic reticulum (ER) stress is a distinct feature observed in neuropathic ... -
Role of Sirt2 in Stress-induced Muscle Atrophy
Skeletal muscle is one of the essential organs in our body, responsible for various functions such as locomotion, transport, protein storage, and thermoregulation. Under certain pathological conditions, there is a reduction ...
