title: Hydrogen sulfide treatment promotes glucose uptake by increasing insulin receptor sensitivity and ameliorates kidney lesions in type 2 diabetes.
abstract: OBJECTIVE
  To examine if hydrogen sulfide (H2S) can promote glucose uptake and provide amelioration in type 2 diabetes.
  
  
  RESULTS
  Treatment with sodium hydrosulfide (NaHS, an H2S donor) increased glucose uptake in both myotubes and adipocytes. The H2S gas solution showed similar effects. The NaHS effects were blocked by an siRNA-mediated knockdown of the insulin receptor (IR). NaHS also increased phosphorylation of the IR, PI3K, and Akt. In Goto-Kakizaki (GK) diabetic rats, chronic NaHS treatment (30 μmol·kg(-1)·day(-1)) decreased fasting blood glucose, increased insulin sensitivity, and increased glucose tolerance with increased phosphorylation of PI3K and Akt in muscles. Similar insulin-sensitizing effects of NaHS treatment were also observed in Wistar rats. Moreover, glucose uptake was reduced in the cells with siRNA-mediated knockdown of the H2S-generating enzyme cystathionine γ-lyase in the presence or absence of exogenous H2S. Moreover, chronic NaHS treatment reduced oxygen species and the number of crescentic glomeruli in the kidney of GK rats.
  
  
  CONCLUSIONS
  This study provides the first piece of evidence for the insulin-sensitizing effect of NaHS/H2S in the both in vitro and in vivo models of insulin resistance.
