Members of the Frizzled family of seven-pass transmembrane proteins serve as receptors for Wnt signalling proteins. Wnt proteins have important roles in the differentiation and patterning of diverse tissues during animal development, and inappropriate activation of Wnt signalling pathways is a key feature of many cancers. An extracellular cysteine-rich(More)
This study investigated the influence of chronically administered curcumin on normal ageing-related parameters: lipid peroxidation, lipofuscin concentration and intraneuronal lipofuscin accumulation, activities of the enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), and Na+, K+, -adenosine triphosphatase (Na+, K+, -ATPase) in different(More)
Close correlations have recently been shown among the late onset complications encountered in diabetes and aging linked to neurobiological disorders. Aging in females and males is considered as the end of natural protection against age related diseases like osteoporosis, coronary heart disease, diabetes, Alzheimer’s disease and Parkinson’s disease,(More)
MOTIVATION Repetitive DNA sequences, besides having a variety of regulatory functions, are one of the principal causes of genomic instability. Understanding their origin and evolution is of fundamental importance for genome studies. The identification of repeats and their units helps in deducing the intra-genomic dynamics as an important feature of(More)
Heat stroke-induced death is a major killer worldwide. Mice were subjected to acute heat stress by exposing them to whole-body hyperthermia (WBH) treatment and were used as a model to study heat stroke. Administration of L-arginine (L-arg, 120 mg/kg, i.p) 2 h after the cessation of WBH rescued the mice from heat-induced death and reduced the hypothermia.(More)
Bacopa monniera is a perennial herb, and is used as a nerve tonic in äyurveda, a traditional medicinal system in India. Aluminium-induced neurotoxicity is well known and different salts of aluminium have been reported to accelerate oxidative damage to biomolecules like lipids, proteins and nucleic acids. The objective of the present study was to investigate(More)
Aluminium (Al) is the most abundant metal known for its neurotoxicity in humans. It gains easy access to the central nervous system under normal physiological conditions and accumulates in different brain regions. It has been reported to be involved in the etiology of several neurodegenerative diseases. In this study, we have investigated the effects of(More)
At least nine inherited neurodegenerative diseases, including Huntington's, are caused by poly(L-glutamine) (polyGln, polyQ) expansions > 35-40 repeats in widely or ubiquitously expressed proteins. Except for their expansions, these proteins have no sequence homologies, and their functions mostly remain unknown. Although each disease is characterized by a(More)
Schisandrin B (SB), a dibenzocyclooctadiene derivative isolated from Schisandra chinensis and used commonly in traditional Chinese medicine for the treatment of hepatitis and myocardial disorders, has been recently shown to modulate cellular redox balance. Since we have shown that cellular redox plays an important role in the modulation of immune responses,(More)
Plumbagin inhibited activation, proliferation, cytokine production, and graft-versus-host disease in lymphocytes and inhibited growth of tumor cells by suppressing nuclear factor-kappaB (NF-kappaB). Plumbagin was also shown to induce reactive oxygen species (ROS) generation in tumor cells via an unknown mechanism. Present report describes a novel role of(More)
