Role of conserved features of initiator tRNA and ribosome heterogeneity in translation initiation in Escherichia coli
Translation is one of the fundamental and core cellular processes catalysed by a ribonucleoprotein complex called ribosome. The process involves four major steps: initiation, elongation, termination and recycling. Initiation ... -
Role of TCP transcription factors in seedling development, leaf morphogenesis and senescence in Arabidopsis thaliana
The TCP gene family encodes non-canonical bHLH transcription factors that act as key regulatory molecules in diverse developmental processes in plants including organ morphogenesis, plant architecture, leaf maturation, and ... -
Genetics of Glioblastoma: Insights into Biology and Therapy Resistance
The central nervous system contains the neural stem cells which differentiate and give rise to the neurons as well as the glial cells which are non-neuronal in nature and provide support and protection to neurons. Unlike ... -
Effects of Steroid Hormones on Insulin Sensitivity and Lipogenesis: An Insight into the Involvement of the Wnt Signaling Pathway
The shift in maternal energy metabolism characteristic of pregnancy is thought to be driven by various hormonal changes, especially of ovarian and placental steroids. In this context, the effect of estradiol (E2), progesterone ... -
Mechanistic insights into the replication of Sesbania mosaic virus
The present thesis deals with the mechanism of replication of Sesbania mosaic virus (SeMV), which belongs to the genus sobemoviruses. Sobemoviruses are single stranded positive sense RNA viruses which infect both mono and ... -
Climate-Growth Relationships of West Himalayan Fir (Abies pindrow) along an Altitudinal Gradient in Northwestern Himalaya
Climate change which includes an increase in temperature, changes in precipitation, retreating of glaciers, has a significant impact on ecosystem dynamics and the social communities. High mountains around the globe are ... -
Biochemical and functional characterisation of cyclic AMP-binding, universal stress proteins from mycobacteria
The genus Mycobacterium harbours several pathogenic species, including M. tuberculosis, the causative agent of tuberculosis, which alone is responsible for nearly 1.3 million deaths globally every year. Understanding the ... -
Regulation of Hepatitis C Virus life-cycle by lncRNA HULC: crosstalk with other host factors
Hepatitis C virus (HCV) is a positive sense single-stranded RNA virus. It belongs to the family Flaviviridae and the genus hepacivirus. Following the receptor-mediated endocytosis, HCV genome is released into the cytoplasm, ... -
Understanding the origins and diversification of Indian blindsnakes
Much of systematics done in the past was based on morphological data. One of the drawbacks of using morphological data is that in groups with conserved morphology, the diversity is often underestimated and relationships ... -
Uncovering of a novel non-taxane anticancer secondary metabolite from Taxol-producing endophytic fungus: Optimization of culture parameters and whole-genome sequence analysis for improved taxane production biosynthesis.
Cancer-related mortalities and morbidities have proven to be a great health burden for human society with immense economic implications. With uncontrolled proliferation of cells as the fundamental principle underlying its ... -
Cholinergic-receptor-independent modulation of intrinsic properties of subicular neurons through inhibition of hyperpolarization-activated cyclic nucleotide-gated channels
Acetylcholine release is vital in tuning the hippocampal theta oscillations. Subiculum, the output region of the hippocampus endowed with different neuronal subtypes, also generates theta oscillations during arousal and ... -
Functional characterization of a new enzymatic activity of the ‘miRNase’-XRN-2 from Caenorhabditis elegans.
Ribonucleic acid (RNA) molecules play a central role in every pivotal process in the cell, and ribonucleases (RNases) are critical for their biogenesis, processing, and degradation. Therefore, RNases are indispensable for ... -
Development of high throughput methodologies to isolate stabilized mutants and to identify interfacial residues
When eukaryotic or unstable proteins are overexpressed in bacteria, these often form insoluble aggregates called inclusion bodies (IB). Refolding the proteins from inclusion bodies can be challenging, resulting in low ... -
Identification and Biochemical Characterization of Novel Inhibitors of Nonhomologous End Joining: Implications in DNA Double-Strand Break Repair and Cancer Therapy
To summarize, in the present study, we have synthesized and characterized three novel NHEJ inhibitors targeting DNA Ligase IV, with several fold better efficacy compared to SCR7 and thus potential to be developed as cancer ... -
Temporal patterns of neural activity governing spatial representation in the hippocampus
Space is a fundamental substrate for animal interactions with the external world. The hippocampus, a region deep within the temporal lobe of mammalian brains, is a multisensory structure that has been heavily implicated ... -
Role of Mycobacterium tuberculosis UvrD1 and UvrD2 helicases in resolving G-quadruplex DNA structures
Unresolved G-quadruplex (G4) DNA secondary structures impede DNA replication and can lead to DNA breaks and to genome instability. Helicases are known to unwind G4 structures and thereby facilitate genome duplication. ... -
PP2A-phosphatase and Polo-like kinase 1 regulates spindle positioning by orchestrating the cortical levels of the dynein adaptor NuMA
The mitotic spindle is a microtubule-based diamond shape structure that captures chromosomes and facilitates their segregation during anaphase. Proper positioning of the mitotic spindle is critical for defining the ... -
Collective escape dynamics of fission-fusion groups in the wild
Collective movement is a fundamental process affecting the survival and reproductive success of group-living animals. Many of the hypothesized benefits of grouping such as predation evasion and foraging efficiency may ... -
Structural and DNA binding properties of ARID domains present in hSWI/SNF chromatin remodeling complex subunits
The SWI/SNF complexes are multisubunit-containing protein complexes that are involved in chromatin-remodeling processes in the eukaryotic cells. In higher eukaryotes, SWI/SNF complexes contain one or more mutually exclusive ... -
Translational readthrough of AGO1 mRNA and its regulation by let-7a microRNA
During translation, the message encoded in mRNAs is decoded by ribosomes to synthesize proteins following strict canonical decoding rules. This process is tightly regulated and several mechanisms exist in cells that ensure ...
