Advances in gene transfer techniques for higher plants have already permitted important achievements towards crop protection and improvement using recombinant DNA technology. Besides plant genetic engineering, the possible use of plant viruses to express foreign genes could be of considerable interest to plant biotechnology. However, insuring containment of(More)
Polyglutamine diseases are a family of inherited neurodegenerative diseases caused by the expansion of CAG repeats within the coding region of target genes. Still the mechanism(s) by which polyglutamine proteins are ubiquitinated and degraded remains obscure. Here, for the first time, we demonstrate that Mahogunin 21 ring finger 1 E3 ubiquitin protein(More)
The protein quality control (QC) system protects cells against cellular toxicity induced by misfolded proteins and maintains overall cellular fitness. Inefficient clearance of or failure to degrade damaged proteins causes several diseases, especially age-linked neurodegenerative disorders. Attenuation of misfolded protein degradation under severe stress(More)
In routine course of life, nonsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed antipyretic, analgesic, and anti-inflammatory drugs. It is a well-proposed notion that treatment of NSAIDs may induce anti-proliferative effects in numerous cancer cells. Ibuprofen from isobutylphenylpropanoic acid is NSAID and used to relieve fever, pain, and(More)
Barley stripe mosaic virus (BSMV) possesses a tripartite genome composed of RNAs alpha, beta and gamma that have been cloned into in vitro transcription vectors from which infectious transcripts can be obtained. The BSMV genome has been engineered here to serve as an expression vector in plant protoplasts. Open reading frame (ORF) b of RNA beta, encoding a(More)
Diclofenac is the most commonly used phenylacetic acid derivative non-steroidal anti-inflammatory drug (NSAID) that demonstrates significant analgesic, antipyretic, and anti-inflammatory effects. Several epidemiological studies have demonstrated anti-proliferative activity of NSAIDs and examined their apoptotic induction effects in different cancer cell(More)
Cells regularly synthesize new proteins to replace old or damaged proteins. Deposition of various aberrant proteins in specific brain regions leads to neurodegeneration and aging. The cellular protein quality control system develop various defense mechanisms against the accumulation of misfolded and aggregated proteins. The mechanisms underlying the(More)
Cells regularly synthesize new proteins to replace old and abnormal proteins for normal cellular functions. Two significant protein quality control pathways inside the cellular milieu are ubiquitin proteasome system (UPS) and autophagy. Autophagy is known for bulk clearance of cytoplasmic aggregated proteins, whereas the specificity of protein degradation(More)
As per the requirement of metabolism and fitness, normal cellular functions are controlled by several proteins, and their interactive molecular and signaling events at multiple levels. Protein quality control (PQC) mechanisms ensure the correct folding and proper utilization of these proteins to avoid their misfolding and aggregation. To maintain the(More)
Proteins are ordered useful cellular entities, required for normal health and organism's survival. The proteome is the absolute set of cellular expressed proteins, which regulates a wide range of physiological functions linked with all domains of life. In aging cells or under unfavorable cellular conditions, misfolding of proteins generates common(More)
