Histone deacetylase (HDAC) inhibition has promise as a therapy for Alzheimer's disease (AD) and other neurodegenerative diseases. Currently, therapeutic HDAC inhibitors target many HDAC isoforms, a particularly detrimental approach when HDAC isoforms are known to have different and specialized functions. We have developed a multiple reaction monitoring(More)
Calmidazolium, a lipophilic cation and putative calmodulin-specific antagonist, inhibited potently the calcium ATPase of sarcoplasmic reticulum (SR) vesicles isolated from skeletal muscle. Based on steady-state measurements of catalytic activity over a range of MgATP, calmidazolium, and SR protein concentrations, the calculated values of the inhibition(More)
The absolute quantitation of amine metabolites from mammalian cell samples was achieved by combining amine standards, isobaric tags, and capillary liquid chromatography (LC) tandem mass spectrometry (MS/MS). Our approach allowed 32 specific amines to be analyzed within a single chromatographic run, with the generation of the calibration curve and absolute(More)
The mechanical stimulus of shear stress has to date been neglected when studying the adhesion of cancer cells to the endothelium. Confluent monolayers of endothelial cells were subjected to either 4 or 15 hours of arterial shear stress. Adhesion of nonmetastatic (MCF-7) and highly metastatic (MDA-MB-435) human breast cancer cells was then quantified using a(More)
Quantification by targeted proteomics has largely depended on mass spectrometry and isotope-labeled internal standards. In addition to traditionally used recombinant proteins or synthetic peptides, concatenated peptides (QconCATs) were introduced as a conceptually new source of internal standard. In the present study, we focused on assessing the length of(More)
Interactions between the hormone melatonin at pharmacological concentrations (10(-3) M) and 2 Hz, 0.3 mT pulsed electromagnetic fields (PEMF) on the proliferation and invasion of human breast cancer cells were studied in vitro. Three types of human breast cancer cells were used in this study: MDA-MB-435, MDA-MB-231, and MCF-7. Results showed that cellular(More)
Alzheimer’s disease (AD) is the sixth leading cause of death and the most costly disease in the US. Despite the enormous impact of AD, there are no treatments that delay onset or stop disease progression currently on the market. This is partly due to the complexity of the disease and the largely unknown pathogenesis of sporadic AD, which accounts for the(More)
Alzheimer's disease has been shown to have a global reduction in gene expression, called an epigenetic blockade, which may be regulated by histone post-translational modifications. Histone H3 has been shown to be highly regulated by phosphorylation. We, therefore, chose H3 for investigation of phosphorylation of the core sites serine-57 (S57) and(More)
Cytochrome P450 27A1 (CYP27A1 or sterol 27-hydroxylase) is a ubiquitous, multifunctional enzyme catalyzing regio- and stereospecific hydroxylation of different sterols. In humans, complete CYP27A1 deficiency leads to cerebrotendinous xanthomatosis or nodule formation in tendons and brain (preferentially in the cerebellum) rich in cholesterol and(More)
