D-Serine, an endogenous co-agonist for the glycine site of the synaptic NMDA glutamate receptor, regulates synaptic plasticity and is implicated in schizophrenia. Serine racemase (SR) is the enzyme that converts L-serine to D-serine. In this study, we demonstrate that SR interacts with the synaptic proteins, postsynaptic density protein 95 (PSD-95) and(More)
UNLABELLED The inositol hexakisphosphate kinases (IP6Ks) are the principal enzymes that generate inositol pyrophosphates. There are three IP6Ks (IP6K1, 2, and 3). Functions of IP6K1 and IP6K2 have been substantially delineated, but little is known of IP6K3's role in normal physiology, especially in the brain. To elucidate functions of IP6K3, we generated(More)
Prostaglandin E2 (PGE2) has been reported to modulate angiogenesis, the process of new blood vessel formation, by promoting proliferation, migration and tube formation of endothelial cells. Endothelial progenitor cells are known as a subset of circulating bone marrow mononuclear cells that have the capacity to differentiate into endothelial cells. However,(More)
Blockade of lysosomal calcium release due to lysosomal lipid accumulation has been shown to inhibit mTORC1 signaling. However, the mechanism by which lysosomal calcium regulates mTORC1 has remained undefined. Herein we report that proper lysosomal calcium release through the calcium channel TRPML1 is required for mTORC1 activation. TRPML1 depletion inhibits(More)
Inhibition of oxidative stress and inflammation in vascular en-dothelial cells (ECs) may represent a new therapeutic strategy against endothelial activation. Sinapic acid (SA), a phenylpropa-noid compound, is found in natural herbs and high-bran cereals and has moderate antioxidant activity. We aimed to develop new SA agents with the properties of(More)
