A 30-d course of oral administration of a semipurified extract of the root of Withania somnifera consisting predominantly of withanolides and withanosides reversed behavioral deficits, plaque pathology, accumulation of β-amyloid peptides (Aβ) and oligomers in the brains of middle-aged and old APP/PS1 Alzheimer's disease transgenic mice. It was similarly(More)
Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by the degeneration of the dopaminergic neurons in the substantia nigra pars compacta (SNpc). Activation of the mixed lineage kinase and c-Jun N-terminal kinase (JNK) has been reported in models of PD. Our focus was to discern whether distinct pathways were activated in(More)

Incidence of Parkinson’s disease (PD) is lower in women compared to men (1:1.46), which is reflected in animal models. However, precise mechanisms are unclear. Administration of MPTP (1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine) to female mice does not lead to mitochondrial complex I inhibition as seen in males and the progressive dopaminergic cell loss(More)
Understanding mechanisms that link aberrant metabolic adaptation and pro-survival responses in glioma cells is crucial towards the development of new anti-glioma therapies. As we have previously reported that CK2 is associated with glioma cell survival, we evaluated its involvement in the regulation of glucose metabolism. Inhibition of CK2 increased the(More)
Transforming growth factor (TGF-β) is associated with the progression of glioblastoma multiforme (GBM)—the most malignant of brain tumors. Since there is a structural homology between TGF-β and human chorionic gonadotropin (hCG) and as both TGF-β and hCG-β are known regulators of oxidative stress and survival responses in a variety of tumors, the role of(More)
Epigenetic regulation by histone methyltransferase G9a is known to control autophagic responses. As the link between autophagy and metabolic homeostasis is widely accepted, we investigated whether G9a affects metabolic circuitries to affect autophagic response in glioma cells. Both pharmacological inhibition and siRNA mediated knockdown of G9a increased(More)
