Small molecules are attractive therapeutics to amplify and direct differentiation of stem cells. They also can be used to understand the regulation of their fate by interfering with specific signaling pathways. Mesenchymal stem cells (MSCs) have the potential to proliferate and differentiate into several cell types, including osteoblasts. Activation of(More)
Dipeptidyl peptidase 1 (DPP1) (EC 3.4.14.1; also known as cathepsin C, cathepsin J, dipeptidyl aminopeptidase, and dipeptidyl aminotransferase) is a lysosomal cysteinyl protease of the papain family involved in the intracellular degradation of proteins. Isolated enzyme assays for DPP1 activity using a variety of synthetic substrates such as dipeptide or(More)
BACKGROUND Ximelagatran, the first oral agent in the new class of direct thrombin inhibitors, was withdrawn from the market due to increased rates of liver enzyme elevations in long-term treatments. Despite intensive pre clinical investigations the cellular mechanisms behind the observed hepatic effects remain unknown. OBJECTIVE The aim of this study was(More)
Wnt activation by inhibiting glycogen synthase kinase 3 (GSK-3) causes bone anabolism in rodents making GSK-3 a potential therapeutic target for osteoporotic and osteolytic metastatic bone disease. To understand the wnt pathway related to human disease translation, the ability of 3 potent inhibitors of GSK-3 (AZD2858, AR79, AZ13282107) to 1) drive(More)
Within the liver, hormonal control of glycogen metabolism allows for rapid release and uptake of glucose from the circulation, providing a reserve of glucose that can be utilised by other organs. Traditionally, cellular glycogen storage has been detected using Periodic acid Schiff (PAS) staining of histopathology samples or a biochemical assay. Colorimetric(More)
