Prion diseases are neurodegenerative disorders where infectious prion proteins (PrP) accumulate in brain leading to aggregation of amyloid fibrils and neuronal cell death. The amino acid sequence 106-126 from prion proteins, PrP(106-126), is highly amyloidogenic and implicated in prion-induced pathologies.

Alfalfa (Medicago sativa L.) is a widely adapted perennial forage crop that has high biomass production potential. Enhanced cellulose content in alfalfa stems would increase the value of the crop as a bioenergy feedstock. We examined if increased expression of

Cyclophilin-D (Cyp-D) is a mitochondrial matrix peptidyl-prolyl isomerase. Because cyclophilins can regulate nuclear gene expression, we examined whether Cyp-D could regulate mitochondrial gene expression. We demonstrated in HEK 293T cells that transfected Cyp-D interacts with mitochondrial transcription factors B1 and

The microtubule-targeting maytansinoids accumulate in cells and induce mitotic arrest at 250- to 1000-fold lower concentrations than those required for their association with tubulin or microtubules. To identify the mechanisms of this intracellular accumulation and exceptional cytotoxicity of maytansinoids we

Journal of Alzheimer's disease : JAD, 49(1), 45-62 (2015-10-08)
Alzheimer's disease (AD), the most common age-related neurodegenerative disorder, is clinically characterized by progressive neuronal loss resulting in loss of memory and dementia. AD is histopathologically characterized by the extensive distribution of senile plaques and neurofibrillary tangles, and synapse loss.
