Lifespan and healthspan benefits of FW1256, a novel hydrogen sulfide donor compound, in C. elegans are independent from effects downstream of eat-2 mutation

Project description:It has been suggested that hydrogen sulfide (H2S) may play a pivotal role in mediating some of these caloric restriction (CR)-associated benefits. We therefore explored whether a novel slow-releasing H2S donor compound, FW1256, mimics CR and reproduces CR-associated effects in normal feeding Caenorhabditis elegans. Using transcriptomics analysis via RNA sequencing, we determined sets of differentially expressed genes (DEG) for FW1256-exposed wild-type C. elegans and eat-2 mutants, a genetic model of CR in C. elegans, relative to unexposed wild-type C. elegans. We found that, while FW1256 affects some of the same downstream genes as eat-2 mutation, global gene expression changes are dissimilar between FW1256-exposed C. elegans and eat-2 mutants, suggesting that novel slow-releasing H2S donor compound, FW1256, does not mimic CR at the transcriptional level.

Transcriptomic study of hydrogen sulfide toxicity in Methylococcus capsulatus

Project description:Stress response of Methylococcus capsulatus str.Bath toward hydrogen sulfide (H2S) was investigated via physiological study and transcriptomic profiling. M. capsulatus (Bath) can grow and tolerate up to 0.75%vol H2S in headspace. Vast change in pH suggests biological relevant sulfide oxidation. Dozens of H2S-sensitive genes were identified from comparison of cell transcriptome in different H2S concentrations. Mc sulfide quinone reductase (SQR) and persulfide dioxygenase were found to be active during sulfide detoxification. Moreover, xoxF, a novel lanthanide(Ln)-dependent methanol dehydrogenase (MDH) was overexpressed in H2S while mxaF, a calcium-dependent MDH, was down-regulated, and such MDH switch phenomenon is also well known to be induced by addition of lanthanide via an as-yet-unknown mechanism. Activities in quorum sensing and RND efflux pump also suggest their role in sulfide detoxification, and might provide insight on the xoxF/mxaF switch mechanism.

Hydrogen sulfide stimulates Mycobacterium tuberculosis respiration and growth to exacerbate TB disease

Project description:The aim of this experiment was to determine how exposure of Hydrogen sulfide impacts gene expression in Mycobacterium tuberculosis. RNA was isolated from actively growing mycobacterial cells (0.6-0.8 OD600) using Trizol according to established protocols (27). Briefly, cells were exposed to 25 µM GYY4137 for 1 hr under carefully controlled conditions (n=3/group) and RNA isolated. Unexposed cells received spent GYY4137 (without any capacity to produce Hydrogen sulfide).

Hydrogen sulfide (H2S) modulates lifespan of C.elegans

Project description:Hydrogen sulfide (H2S) is formed naturally from L-cysteine in a variety of mammalian and non-mammalian cells. To date, numerous biological effects have been ascribed to H2S including control of cardiovascular, immune and nervous function. Over or under production of H2S has been observed in several disease states including hypertension and inflammation. In addition, it has been stipulated that H2S may affect the ageing process. The model nematode Caenorhabditis elegans is ideally suited for assessing drug effects on lifespan since it is relatively short-lived, can be easily exposed to drugs and its genome is fully sequenced and widely annotated.

The Global Transcriptional Response of Fission Yeast to Hydrogen Sulfide

Project description:Hydrogen sulfide (H2S) as an important gasotransmitter has fundamental roles in human diseases. The cellular effect of H2S has received lots of attention recently. H2S can affect ion channels, transcription factors and kinase in mammals. The mechanism of cellular effect of H2S is not completely understood. We used fission yeast as a model organism to study the global transcriptional profile in response to H2S by microarray.

Changes in relative transcript amounts caused by hydrogen sulfide treatment, deletion of BigR, and BigR mutant complement in Acinetobacter baumannii

Project description:Acinetobacter baumannii is an opportunistic nosocomial pathogen that is the causative agent of several serious infections in humans. Here, we investigate the response of A. baumannii toward sodium sulfide (Na2S), known to be associated with some biofilms at oxic/anoxic interfaces, as a model for how this major human pathogen manages sulfide homeostasis. These results reveal that A. baumannii encodes two persulfide‑sensing transcriptional regulators, a primary sigma54‑dependent transcriptional activator (FisR), and a secondary system controlled by the persulfide‑sensing repressor biofilm growth‑associated repressor (BigR) both of which regulate operons encoding for sulfide detoxification or transportation. In addition, sulfide induces an alternative cytochrome bd oxidase which is refractory to inhibition by H2S and represses importers of alternate sulfur sources. Lastly, our results suggest additional genes regulated by BigR beyond sulfide detoxification including genes associated with assembly of type 1 chaperone-usher pilus.
