Abstract
Although gasotransmitters nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) receive a bad connotation; in low concentrations these play a major governing role in local and systemic blood flow, stomach acid release, smooth muscles relaxations, anti-inflammatory behavior, protective effect and more. Many of these physiological processes are upstream regulated by gut peptides, for instance gastrin, cholecystokinin, secretin, motilin, ghrelin, glucagon-like peptide 1 and 2. The relationship between gasotransmitters and gut hormones is poorly understood. In this review, we discuss the role of NO, CO and H2S on gut peptide release and functioning, and whether manipulation by gasotransmitter substrates or specific blockers leads to physiological alterations.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 693:133490. [PMID: 31635006 DOI: 10.1016/j.scitotenv.2019.07.296] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 05/10/2019] [Accepted: 07/18/2019] [Indexed: 05/20/2023]
Abstract
Lead is among the most common toxic heavy metals and its contamination is of great public concern. Bacillus coagulans is the probiotic which can be considered as the lead absorption sorbent to apply in the lead contaminant water directly or indirectly. A better understanding of the lead resistance and tolerance mechanisms of B. coagulans would help further its development and utilization. Wild-type Bacillus coagulans strain R11 isolated from a lead mine, was acclimated to lead-containing culture media over 85 passages, producing two lead-adapted strains, and the two strains shown higher lead intracellular accumulation ability (38.56-fold and 19.36-fold) and reducing ability (6.94-fold and 7.44-fold) than that of wild type. Whole genome sequencing, genome resequencing, and comparative transcriptomics identified lead resistance and tolerance process significantly involved in these genes which regulated glutathione and sulfur metabolism, flagellar formation and metal ion transport pathways in the lead-adapted strains, elucidating the relationships among the mechanisms regulating lead deposition, deoxidation, and motility and the evolved tolerance to lead. In addition, the B. coagulans mutants tended to form flagellar and chemotaxis systems to avoid lead ions rather than export it, suggesting a new resistance strategy. Based on the present results, the optimum lead concentration in environment should be considered when employed B. coagulans as the lead sorbent, due to the bacteria growth ability decreased in high lead concentration and physiology morphology changed could reduce the lead removal effectiveness. The identified deoxidization and compound secretion genes and pathways in B. coagulans R11 also are potential genetic engineering candidates for synthesizing glutathione, cysteine, methionine, and selenocompounds.

Abstract
BACKGROUND The inhibitory effects of H2 S on spontaneous contractions of smooth muscles of small, and large intestines well-established but its role in the pathophysiology of diarrhea has not been identified. Therefore, this study evaluated the role of exogenous H2 S (NaHS) on diabetic-induced diarrhea and determined mRNA expression of cystathionine β-lyase (CSE) and cystathionine γ-synthase (CBS) in diabetic rats. METHODS In order to evaluate antidiarrheal effect of H2 S, normal and diabetic rats received NaHS and L-Cysteine and the total number of fecal pellets (FP) determined. The effect of NaHS on intestinal transit ratio (ITR) was also evaluated in diabetic rats. The level of mRNA expressions of CBS and CSE determined in smooth muscles of jejunum, ileum, and colon in normal, and diabetic rats. The effect of NaHS on frequency and tension of spontaneous contractions of smooth muscle strips of colon, ileum, and jejunum were investigated. KEY RESULTS NaHS decreased ITR, total number of FP, frequency and tension of spontaneous contractions of colon, ileum, and jejunum muscle strips in diabetic rats. The level of mRNA expression of CSE and CBS in diabetic rats were lower than in normal rats. NaHS, and L-Cysteine decreased the number of FP in normal rats. CONCLUSIONS & INFERENCES These findings showed NaHS effectively controlled diarrhea in diabetic rats through decreasing the frequency, and tension of spontaneous contraction of smooth muscles of large, and small intestines. The increased frequency and tension of spontaneous contractions of smooth muscles in diabetic rats may be due to down-regulation of H2 S biosynthesis enzymes.

Delayed gastric emptying in diabetic rats caused by decreased expression of cystathionine gamma lyase and H 2 S synthesis: in vitro and in vivo studies. Neurogastroenterol Motil 2016; 28:1677-1689.

Abstract
BACKGROUND This study aimed to evaluate the role of H2 S on gastric emptying rate (GER) and also to determine the effect of gastric distention on mRNA and protein expression of cystathionine β-lyase (CBS) and cystathionine γ-synthase (CSE) in diabetic-gastroparetic and normal rats. METHODS Adult normal rats intraperitoneally received either propargylglycine (PAG), L-cysteine or NaHS 30 min prior to GER marker (acetaminophen) to investigate H2 S involvement in GER and the same protocols were performed in diabetes-induced gastroparesis rats. The role of calcitonin gene related peptide (CGRP) neurons in the prokinetic effect of endogenous H2 S on GER was determined. The level of CBS and CSE expressions in response to gastric distention were also determined. The effect of H2 S on frequency and tension of spontaneous contractions of gastric smooth muscle strips was investigated. KEY RESULTS Our results showed that: (i) H2 S and L-cysteine increased GER in gastroparetic and normal rats. (ii) The increased levels of CSE expression in response to gastric distention in diabetic rats were lower than in normal rats. (iii) PAG inhibited the excitatory effect of capsaicin on GER and on tension of spontaneous contractions of strips. (iv) Hydrogen sulphide increased the frequency and tension of spontaneous contractions of gastric strip muscles in normal and diabetic rats. CONCLUSIONS & INFERENCES The results showed that delayed GER in diabetic rats can be due to down-regulation of H2 S biosynthesis enzyme, CSE and suggested that a potential prokinetic role for H2 S to treat the delayed gastric emptying in diabetic patients.
