The hormone-induced depletion of cellular Ca stores provides a signal for the Ca2+ influx into electrically non-excitable cells; however, the underlying molecular mechanisms remain elusive. Therefore, we analyzed bradykinin-activated Ca2+ influx into human foreskin fibroblast cells, HF-15, by fura-2 and

Inward currents activated by 8-bromc-cGMP and by muscarinic agonist were compared in N1E-115 mouse neuroblastoma cells using perforated-patch voltage clamp and Fura-2 imaging. The cGMP analog activates a voltage-independent inward current that is carried at least in part by Ca2+

Chemotherapy of brain glioma faces a major obstacle owing to the inability of drug transport across the blood-brain barrier (BBB). Besides, neovasculatures in brain glioma site result in a rapid infiltration, making complete surgical removal virtually impossible. Herein, we reported

Nitric oxide (NO) and carbon monoxide (CO) have been identified as two diffusible signaling messengers in the brain, capable of stimulating soluble guanylate cyclase. Locus coeruleus (LC) is rich in the alpha 1 and beta 1 subunits of soluble guanylate

In the present study, the inhibitory effect of the cGMP analog (Rp)-8-(para-chlorophenylthio)guanosine-3',5'-cyclic monophosphorothioate ((Rp)-8-pCPT-cGMPS) on the cGMP-dependent protein kinase-mediated protein phosphorylation in intact human platelets was investigated. In vitro phosphorylation experiments with the substrate kemptide demonstrated an inhibition of the
