Targeting the TRPM4 Channel for Neurologic Diseases: Opportunity and Challenge.

As a monovalent cation channel, the transient receptor potential melastatin 4 (TRPM4) channel is a unique member of the transient receptor potential family. Abnormal TRPM4 activity has been identified in various neurologic disorders, such as stroke, spinal cord injury, traumatic brain injury, multiple sclerosis, amyotrophic lateral sclerosis, pathologic pain, and epilepsy. Following brain hypoxia/ischemia and inflammation, TRPM4 up-regulation and enhanced activity contribute to the cell death of neurons, vascular endothelial cells, and astrocytes.

Glycerophosphodiester phosphodiesterase 1 mediates G3P accumulation for Eureka lemon resistance to citrus yellow vein clearing virus.

Glycerophosphodiester phosphodiesterase 1 (GDPD1) plays an important function in the abiotic stress responses and participates in the accumulation of sn-glycerol-3-phosphate (G3P) in plants, which is key to plant systemic acquired resistance (SAR). However, the role of GDPD1 in plant responses to biotic stress remains poorly understood. This study characterized the antivirus function of the gene (designated as ) from Eureka lemon.

Dysfunctional astrocyte glutamate uptake in the hypothalamic paraventricular nucleus contributes to visceral pain and anxiety-like behavior in mice with chronic pancreatitis.

Abdominal visceral pain is a predominant symptom in patients with chronic pancreatitis (CP); however, the underlying mechanism of pain in CP remains elusive. We hypothesized that astrocytes in the hypothalamic paraventricular nucleus (PVH) contribute to CP pain pathogenesis. A mouse model of CP was established by repeated intraperitoneal administration of caerulein to induce abdominal visceral pain.

Effects of clitorienolactones from Clitoria ternatea root on calcium channel mediating hippocampal long-term potentiation in rats induced chronic cerebral hypoperfusion.

Chronic cerebral hypoperfusion (CCH) is a common mechanism of acute brain injury due to impairment of blood flow to the brain. Moreover, a prolonged lack of oxygen supply may result in cerebral infarction or global ischemia, which subsequently causes long-term memory impairment. Research on using Clitoria ternatea root extract for treating long-term memory has been studied extensively.

evaluation of monoclonal antibody M4M using a humanised rat model of stroke demonstrates attenuation of reperfusion injury via blocking human TRPM4 channel.

Background: Blocking Transient Receptor Potential Melastatin 4 (TRPM4) in rodents by our antibody M4P has shown to attenuate cerebral ischaemia-reperfusion injury. Since M4P does not interact with human TRPM4, the therapeutic potential of blocking human TRPM4 remains unclear. We developed a monoclonal antibody M4M that inhibited human TRPM4 in cultured cells.

Effect of agricultural management practices on rice yield and greenhouse gas emissions in the rice-wheat rotation system in China.

Agricultural management practices (AMPs) have the potential to significantly enhance crop yield, albeit with the possible side effect of escalating greenhouse gas emissions. Few studies have undertaken a comprehensive quantification of the impact of AMPs on crop production and soil GHG, particularly in identifying the optimal AMPs for rice cultivation within rice-wheat rotation system. Here, we combined data analysis and keyword search methods on 1433 individual experimental observations from 172 studies on diverse soil types in the subtropical monsoon climate zone of China to assess the impact of AMPs on rice yield, CH and NO emissions, total greenhouse gas emissions (TGHGE).

In order to facilitate the analysis and processing of optical signals, an FPGA-based CCD signal acquisition and data transmission system is designed in this work. The system uses an FPGA as the main control device, the TCD1304DG/AP chip as the optical signal detector, and the CYUSB3KIT-003 development board product by Cypress for data transmission. Verilog and Python languages are employed for modular design and on-board verification.

TRPM4 blocking antibody reduces neuronal excitotoxicity by specifically inhibiting glutamate-induced calcium influx under chronic hypoxia.

Excitotoxicity arises from unusually excessive activation of excitatory amino acid receptors such as glutamate receptors. Following an energy crisis, excitotoxicity is a major cause for neuronal death in neurological disorders. Many glutamate antagonists have been examined for their efficacy in mitigating excitotoxicity, but failed to generate beneficial outcome due to their side effects on healthy neurons where glutamate receptors are also blocked.
