dc.description.abstract | Recent studies in mice and humans demonstrated the relevance of H2S synthesising
enzymes, such as CTH, CBS, and MPST, in the physiology of adipose tissue and the differentiation
of preadipocyte into adipocytes. Here, our objective was to investigate the combined role of CTH,
CBS, and MPST in the preservation of adipocyte protein persulfidation and adipogenesis. Combined
partial CTH, CBS, and MPST gene knockdown was achieved treating fully human adipocytes with
siRNAs against these transcripts (siRNA_MIX). Adipocyte protein persulfidation was analyzed
using label-free quantitative mass spectrometry coupled with a dimedone-switch method for protein
labeling and purification. Proteomic analysis quantified 216 proteins with statistically different levels
of persulfidation in KD cells compared to control adipocytes. In fully differentiated adipocytes, CBS
and MPST mRNA and protein levels were abundant, while CTH expression was very low. It is
noteworthy that siRNA_MIX administration resulted in a significant decrease in CBS and MPST
expression, without impacting on CTH. The combined partial knockdown of the CBS and MPST
genes resulted in reduced cellular sulfide levels in parallel to decreased expression of relevant
genes for adipocyte biology, including adipogenesis, mitochondrial biogenesis, and lipogenesis, but
increased proinflammatory- and senescence-related genes. It should be noted that the combined
partial knockdown of CBS and MPST genes also led to a significant disruption in the persulfidation
pattern of the adipocyte proteins. Although among the less persulfidated proteins, we identified
several relevant proteins for adipocyte adipogenesis and function, among the most persulfidated,
key mediators of adipocyte inflammation and dysfunction as well as some proteins that might play a
positive role in adipogenesis were found. In conclusion, the current study indicates that the combined
partial elimination of CBS and MPST (but not CTH) in adipocytes affects the expression of genes
related to the maintenance of adipocyte function and promotes inflammation, possibly by altering
the pattern of protein persulfidation in these cells, suggesting that these enzymes were required for
the functional maintenance of adipocytes. | es |
