Glutamate is one of the most prominent neurotransmitter in the body, present in over 50% of nervous tissue and plays an important role in neuronal excitation. This neuronal excitation is short-lived and is followed by depression. Multiple abnormal triggers such as energy deficiency, oxidative stress, mitochondrial dysfunction, calcium overload, etc can lead(More)
Enhancing cyclic nucleotides signaling by inhibition of phosphodiesterases (PDEs) is known to be beneficial in disorders associated with cognitive decline. The present study was designed to investigate the effect of vinpocetine (PDE1 inhibitor) on intracerebroventricular (i.c.v.) streptozotocin induced experimental sporadic dementia of Alzheimer's type.(More)
Cyclic nucleotides viz cGMP and cAMP are known to play an important role in learning and memory processes. Enhancement of cyclic nucleotide signalling through inhibition of phosphodiesterases (PDEs) has been reported to be beneficial in several neurodegenerative disorders associated with cognitive decline. The present study was undertaken to investigate the(More)
The present study was designed to investigate the effect of licofelone—a dual cyclooxygenase/5-lipoxygenase (COX/5-LOX) inhibitor in intracerebroventricular streptozotocin (ICV-STZ)-induced cognitive deficit and biochemical abnormalities in rats. ICV-STZ is a widely used model of sporadic Alzheimer’s disease. In this study, STZ was administered(More)
The cancer drug discovery field has placed much emphasis on the identification of novel and cancer-specific molecular targets. A rich source of such targets for the design of novel anti-tumor agents is the ubiqutin-proteasome system (UP-S), a tightly regulated, highly specific pathway responsible for the vast majority of protein turnover within the cell.(More)
Glutamate and γ-aminobutyric acid (GABA) are the major excitatory and inhibitory neurotransmitter systems, respectively in the central nervous system (CNS). Dysregulation, in any of these or both, has been implicated in various CNS disorders. GABA acts via ionotropic (GABA(A) and GABA(C) receptor) and metabotropic (GABA(B)) receptor. Dysregulation of(More)
Upregulation in calcineurin (CaN) signaling has been implicated in various neurodegenerative disorders. In the present study, we have investigated the effect of FK506--a CaN inhibitor--on streptozotocin (STZ)-induced experimental dementia of the Alzheimer's type in rats. STZ was administered intracerebroventricularly to induce a cognitive deficit and(More)
The extracellular signal-regulated kinase-1 and 2 (ERK1/2) proteins play an important role in cancer cell proliferation and survival. ERK1/2 proteins also are important for normal cell functions. Thus, anti-cancer therapies that block all ERK1/2 signaling may result in undesirable toxicity to normal cells. As an alternative, we have used computational and(More)
Movement disorders rank among the most common neurological disorders. During the last two decades substantial progress has been made in understanding of the pathological basis of these disorders. Although, several mechanisms have been proposed, downregulation of cyclic nucleotide mediated signaling cascade has consistently been shown to contribute to the(More)
INTRODUCTION Prostate cancer being the second leading cause of death in men in Western countries remains a major challenge in healthcare. Several novel agents targeting signaling pathways in prostate cancer have recently been approved by the US Food and Drug Administration (FDA) but there is still an unmet need for new treatment strategies for(More)
