C2H2-type zinc finger proteins (ZFPs) have been shown to play important roles in the responses of plants to oxidative and abiotic stresses, and different members of this family might have different roles during stresses. Here a novel abscisic acid (ABA)- and hydrogen peroxide (H₂O₂)-responsive C2H2-type ZFP gene, ZFP36, is identified in rice. The analyses(More)
Calcium-dependent protein kinases (CDPKs) have been shown to be involved in abscisic acid (ABA)-mediated physiological processes, including seed germination, post-germination growth, stomatal movement, and plant stress tolerance. However, it is not clear whether CDPKs are involved in ABA-induced antioxidant defence. In the present study, the role of the(More)
BACKGROUND AND PURPOSE Sinomenine (SN), a bioactive alkaloid, has been utilized clinically to treat rheumatoid arthritis in China. Our preliminary experiments indicated that it could protect PC12 cells from oxygen-glucose deprivation-reperfusion (OGD-R), we thus investigated the possible effects of SN on cerebral ischaemia and the related mechanism.

Deficits in learning and memory accompanied by age-related neurodegenerative diseases are closely related to the impairment of synaptic plasticity. In this study, we investigated the role of thiol redox status in the modulation of the N-methyl-d-aspartate receptor (NMDAR)-dependent long-term potentiation (LTP) in CA1 areas of hippocampal slices. Our results(More)
C(2) H(2) -type zinc finger proteins (ZFPs) are thought to play important roles in modulating the responses of plants to drought, salinity and oxidative stress. However, direct evidence is lacking for the involvement of these ZFPs in abscisic acid (ABA)-induced antioxidant defense in plants. In this study, the role of the rice (Oryza sativa L. sub. japonica(More)
Orexin-A is an important neuropeptide involved in the regulation of feeding, arousal, energy consuming, and reward seeking in the body. The effects of orexin-A have widely studied in neurons but not in astrocytes. Here, we report that OX1R and OX2R are expressed in cultured rat astrocytes. Orexin-A stimulated the phosphorylation of extracellular(More)
Intermedin (IMD) is a member of the calcitonin/calcitonin gene-related peptide (CGRP) family and has similar or more potent cardiovascular actions than adrenomedullin (ADM) and any other CGRP. The aim of the present work is to study the effects of IMD1-53 on cardiac fibroblast fibrosis in vivo and in vitro. Myocardial infarction model was prepared by(More)
Reactive oxygen species (ROS) is reported to be a critical pathogenic factor and mitochondria is one of the susceptible subcellular organs for oxidative damage. Methionine sulfoxide reductase A (MsrA) is a key anti-oxidant enzyme associated with cytoprotection and previous reports have revealed its importance in mitochondrial function. The anti-oxidation of(More)
Acid-sensing ion channels (ASICs) have been reported to play a role in the neuronal dopamine pathway, but the exact role in neurotransmitter release remains elusive. Human neuroblastoma SH-SY5Y is a dopaminergic neuronal cell line, which can release monoamine neurotransmitters. In this study, the expression of ASICs was identified in SH-SY5Y cells to(More)
BACKGROUND AND PURPOSE Impairment of glucose utilization contributes to neuronal degeneration of Alzheimer's disease patients. Cellular glucose utilization can be regulated by calcium-dependent signaling pathways. Resveratrol (RSV) is a plant-derived polyphenol with multiple beneficial effects, including neuroprotection and metabolic improvement. Here, we(More)
