In the heart, Na⁢-Ca2⁢ exchange (NCX) is the major Ca2⁢ extrusion mechanism. NCX has been considered as a relaxation mechanism, as it reduces global [Ca2⁢]i raised during activation. However, if NCX locates in the close proximity to the ryanodine receptor, then NCX would curtail Ca2⁢ before its diffusion to global Ca2⁢i. This will result in a global [Ca2⁢]i decrease especially during its ascending phase rather than descending phase. Therefore, NCX would...

TRPM7, a cation channel protein permeable to various metal ions such as Mg2⁢, is ubiquitously expressed in variety of cells including lymphocytes. The activity of TRPM7 is tightly regulated by intracellular Mg2⁢, thus named Mg2⁢-inhibited cation (MIC) current, and its expression is known to be critical for the viability and proliferation of B lymphocytes. In this study, the level of MIC current was compared between immature (WEHI-231) and mature (Bal-17) B lymphocytes. In both...

The present study were designed to characterize the action mechanisms of acetylcholine (ACh)- induced endothelium-dependent relaxation in arteries precontracted with high K⁢ (70 mM). For this, we simultaneously measured both muscle tension and cytosolic free Ca2⁢ concentration ([Ca2⁢]i), using fura-2, in endothelium-intact, rabbit carotid arterial strips. In the artery with endothelium, high K⁢ increased both [Ca2⁢]i and muscle tension whereas ACh (10μM)...

Schwann cells play an important role in peripheral nerve regeneration. Upon neuronal injury, activated Schwann cells clean up the myelin debris by phagocytosis, and promote neuronal survival and axon outgrowth by secreting various neurotrophic factors. However, it is unclear how the nerve injury induces Schwann cell activation. Recently, it was reported that certain cytoplasmic molecules, which are secreted by cells undergoing necrotic cell death, induce immune cell activation via the toll-like...

The effects of fetal mesencephalic cell grafts on the restoration of nigrostriatal dopaminergic function were studied in the intrastriatal 6-hydroxydopamine-lesioned rats. Four weeks after lesioning, transplantation of ventral mesencephalic cells from embryonic day 14 fetuses showed the number of tyrosine hydroxylase (TH) positive cells and fiber outgrowth in the grafted striatum, and significantly ameliorated symptomatic motor behavior of the animals, as determined by apomorphine-induced...

A variety of G protein coupled receptors (GPCRs) are expressed in the presynaptic terminals of central and peripheral synapses and play regulatory roles in transmitter release. The patch-clamp whole-cell recording technique, applied to the calyx of Held presynaptic terminal in brainstem slices of rodents, has made it possible to directly examine intracellular mechanisms underlying the GPCR-mediated presynaptic inhibition. At the calyx of Held, bath-application of agonists for GPCRs such as GABAB...

Mechanical stimuli to the cardiac myocytes initiate many biochemical and physiological events. Stretch-activated cation channels have been suggested to mediate these events. In this study, cell-attached and inside-out excised-patch clamp methods were used to identify stretch-activated cation channels in adult rat atrial myocytes. Channel openings were increased in cell-attached configuration when negative pressure was applied to the pipette, and also in inside-out excised patches by negative...

3-Nitropropionic acid (3-NP) inhibits electron transport in mitochondria, leading to a metabolic failure. In order to elucidate the mechanism underlying this toxicity, we examined a few biochemical changes possibly involved in the process, such as metabolic inhibition, generation of reactive oxygen species (ROS), DNA strand breakage, and activation of Poly(ADP-ribose) polymerase (PARP). Exposure of SK-N-BE(2)C neuroblastoma cells to 3-NP for 48 h caused actual cell death, while inhibition of...

Coptis chinensis (CC) is one of the traditional herbs used in Oriental medicine for the treatment of gastrointestinal disorders, anxiety, and insomnia. In this study, neurotrophic and neuritogenic effects of CC on rat pheochromocytoma (PC12) cells were evaluated. Pretreatment of PC12 cells with water extracts of CC (120μg /ml) produced considerable outgrowth of neurites that is comparable to the effect of nerve growth factor (NGF). Therefore, neurite outgrowth was quantified and expression of...

We have previously reported that expression of the somatostatin receptor subtypes, sst1-5, is differentially regulated by growth hormone (GH)-releasing hormone (GHRH) and forskolin (FSK), in vitro. GHRH binds to membrane receptors selectively located on pituitary somatotropes, activates adenylyl cyclase (AC) and increases sst1 and sst2 and decreases sst5 mRNA levels, without significantly altering the expression of sst3 and sst4. In contrast FSK directly activates AC in all pituitary cell types...
