GSE133942: The effect of slow and rapid H2S production on the levels of LPS-induced proinflammatory mediators and transcription in different human cell cultures

Bulk RNA sequencing

In this study we investigated the effect of two different agents producing hydrogen sulfide (H2S) on LPS-induced inflammatory mediators such as TNFa, NO and ROS. The agents (GYY4137 and sodium hydrosulfide) applied differ significantly by the kinetics of H2S release. In the investigation we compared the effects of H2S release on the LPS-induced inflammation exploring SH-SY5Y human neuroblastoma cell line and human promonocytic cell line, THP-1. Our data clearly show that both hydrogen sulfide producing agents significantly reduced the production of the investigated proinflammatory mediators when applied both before and after LPS administration. Furthermore, transcriptomic studies demonstrated that H2S release ameliorates the expression of multiple proinflammatory genes up-regulated due to LPS administration. However, the pattern of changes observed in transcriptome differs dramatically depending on the time of H2S release (before or after LPS-challenge).
