Expression levels of cystathionine-γ-lyase (CSE), hydrogen sulfide (H₂S) and angiotensin II type 1 receptor (AGTR1) in rats with hepatic fibrosis. (A) The mRNA expression levels of CSE were measured in each group using reverse transcription-quantitative polymerase chain reaction, which demonstrated similar results between week three and four. (B) H₂S levels were decreased in the DL-propargylglycine group, and conversely increased in the sodium hydrosulfide group, as compared with the control. The error bars indicated the mean ± standard deviation (^**P<0.01 vs. normal control group, ^##P<0.01 vs. the model group). HF, hepatic fibrosis.
