Parkinson's disease (PD) is related to excess production of reactive oxygen species (ROS) or inadequate and impaired detoxification by endogenous antioxidants, alterations in catecholamine metabolism, alterations in mitochondrial electron transfer function, and enhanced iron deposition in the substantia nigra. The concept that oxidative stress is an(More)
Parkinson's disease (PD) is characterized by the progressive loss of the dopaminergic neurons leading to decrease in striatal dopamine (DA) levels. In the present review, our focus was on recent advances in the treatment procedures of PD to achieve an increase in deficient tyrosine hydroxylase (TH) activity and/or expression. Stimulation of residual TH(More)
Alzheimer's disease (AD) and type 2 diabetes mellitus (T2DM) are two debilitating health disorders afflicting millions worldwide. Recent research has revealed similarities between AD and T2DM. Both these protein conformational disorders are associated with obesity, insulin resistance, inflammation and endoplasmic reticulum stress, en-route initiation and/or(More)
Formation of advanced glycation end products (AGE) is crucially involved in the several pathophysiologies associated with ageing and diabetes, for example arthritis, atherosclerosis, chronic renal insufficiency, Alzheimer’s disease, nephropathy, neuropathy, and cataracts. Because of devastating effects of AGE and the significance of bovine serum albumin(More)
Parkinson's disease (PD) is associated with neurodegeneration of the nigrostriatal tract and is accompanied with loss of tyrosine hydroxylase (TH) and dopamine (DA). Development of neuroprotective strategies targeting PD is often undermined by lack of proper understanding of processes contributing to the pathology. In this mini review we have tried to(More)
Pancreatic thiol proteinase inhibitor (PTPI), a variant of cystatin superfamily of cysteine protease inhibitors, has been isolated from pancreas of Capra hircus. In the present study, we examined the effects of acid denaturation and a co-solvent on PTPI with a focus on protein conformational changes and amyloid fibril formation. The results demonstrate that(More)
Cystatins are thiol proteinase inhibitors ubiquitously present in mammalian body and serve various important physiological functions. In the present study, we examined the effects of acid denaturation on newly identified thiol protease inhibitors from the lungs of Capra hircus (Goat) with a focus on protein conformational changes and amyloid fibril(More)
Nutrient sensing receptors are key metabolic mediators of responses to dietary and endogenously derived nutrients. These receptors are largely G-protein-coupled receptors (GPCRs) and many are gaining significant interest as drug targets with a potential therapeutic role in metabolic diseases. A distinct subclass of nutrient sensing GPCRs, two short chain(More)
The regulation of pancreatic β cell mass is a critical factor to help maintain normoglycemia during insulin resistance. Nutrient-sensing G protein-coupled receptors (GPCR) contribute to aspects of β cell function, including regulation of β cell mass. Nutrients such as free fatty acids (FFAs) contribute to precise regulation of β cell mass by signaling(More)
Goat liver cystatin was subjected to various chemical modifications in order to ascertain the amino acid residues responsible for its structural and functional integrity. Modification of tryptophan by HNBB led to the complete inactivation of the protein. The inactivation was also accompanied by the complete loss of tryptophan fluorescence at 340 nm. The(More)
