Gasotransmitters are biologically produced gaseous signalling molecules. As gases with potent biological activities, they are toxic as air pollutants, and the sulfurous compounds are used as fumigants. Most investigations focus on medical aspects of gasotransmitter biology rather than toxicity toward invertebrate pests of agriculture. In fact, the pathways for the metabolism of sulfur containin...

Bearing the public image of a deadly "gas of rotten eggs," hydrogen sulfide (H2S) can be generated in many types of mammalian cells. Functionally, H2S has been implicated in the induction of hippocampal long-term potentiation, brain development, and blood pressure regulation. By acting specifically on KATP channels, H2S can hyperpolarize cell membranes, relax smooth muscle cells, or decrease ne...

Creation of both gametes, sperm and oocyte, and their fusion during fertilization are essential step for beginning of life. Although molecular mechanisms regulating gametogenesis, fertilization, and early embryonic development are still subjected to intensive study, a lot of phenomena remain unclear. Based on our best knowledge and own results, we consider gasotransmitters to be essential for v...

MicroRNAs are well established regulators of Inflammatory Bowel Disease (IBD), such as Crohn’s disease (CD) and ulcerative colitis (UC). Furthermore, gasotransmitters including nitric oxide (NO), carbon monoxide (CO) and hydrogen sulphide (H2S) also seem to play important role in this disease pathogenesis. In the present study, we aimed to investigate the relationship between microRNAs and gaso...

Historically acknowledged as toxic gases, hydrogen sulfide (H2S) and nitric oxide (NO) are now recognized as the predominant members of a new family of signaling molecules, "gasotransmitters" in mammals. While H2S is biosynthesized by three constitutively expressed enzymes (CBS, CSE, and 3-MST) from L-cysteine and homocysteine, NO is generated endogenously from L-arginine by the action of vario...

Nitric oxide (NO) and carbon monoxide (CO) are gasotransmitters that suppress the development of severe forms of malaria associated with Plasmodium infection. Here, we addressed the mechanism underlying their protective effect against experimental cerebral malaria (ECM), a severe form of malaria that develops in Plasmodium-infected mice, which resembles, in many aspects, human cerebral malaria ...
