Smooth muscle caldesmon was phosphorylated by smooth muscle calmodulin-dependent protein kinase II. The extent of phosphorylation obtained was 5.65 mol of phosphate/mol of caldesmon. Phosphorylated protein was subjected to the complete trypsin proteolysis and the produced phosphopeptides were purified by C-8 reverse phase chromatography. Nine phosphopeptides were isolated and by amino acid sequ...
We investigated the combined moisturizing effect of liposomal serine and a cosmeceutical base selected in this study. Serine is a major amino acid consisting of natural moisturizing factors and keratin, and the hydroxyl group of serine can actively interact with water molecules. Therefore, we hypothesized that serine efficiently delivered to the stratum corneum (SC) of the skin would enhance th...
Background: To investigate the levels and clinical significance of serum homocysteine (Hcy), high-density lipoprotein cholesterol (HDL-C), visceral adipose tissue-derived serine protease inhibitor (vaspin), fat-specific adipokine (visfatin) in elderly patients with different types coronary heart disease (CHD).
OBJECTIVE Glutamatergic neurotransmission via the N-methyl-d-aspartate (NMDA) receptor is integral to the pathophysiology of depression. This study was performed to examine whether amino acids related to NMDA receptor neurotransmission are altered in the serum of patients with depression. METHOD We measured the serum levels of d-serine, l-serine, glycine, glutamate and glutamine in patients w...
AIM To study the alterations of the expressions of serine racemase in C57BL/6 mouse brain after permanent focal cerebral ischemia. METHODS The mRNA level and the protein level of serine racemase were assayed by semiquantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot, respectively. The amount of D-serine and L-serine were measured by HPLC. RESULTS High leve...
Hyperphosphorylation of the cardiac Ca2+ release channel (ryanodine receptor, RyR2) by protein kinase A (PKA) at serine-2808 has been proposed to be a key mechanism responsible for cardiac dysfunction in heart failure (HF). However, the sites of PKA phosphorylation in RyR2 and their phosphorylation status in HF are not well defined. Here we used various approaches to investigate the phosphoryla...
To investigate the mechanisms underlying the neuroprotective effect of L-serine, permanent focal cerebral ischemia was induced by occlusion of the middle cerebral artery while monitoring cerebral blood flow (CBF). Rats were divided into control and L-serine-treated groups after middle cerebral artery occlusion. The neurological deficit score and brain infarct volume were assessed. Nissl stainin...
