Huang Gan formula (HGF) is a new traditional Chinese herbal medicine created
according to the basic theory of traditional Chinese medicine. The aim of this
study is to evaluate the effects of HGF on chronic kidney disease and determine
the mechanisms of action. The extract of HGF was prepared, and qualitative and
quantitative determination of phytochemical was performed with quadrupole
time-of-flight mass spectrometer and high-performance liquid chromatography.
Sprague-Dawley rats (n=72) were submitted to 5/6 nephrectomy (Nx), and then
respectively treated with uremic clearance granule, losartan, HGF low dose, HGF
middle dose, and HGF high dose once per day for 12 weeks. The sham group of
operated rats (n=22) was treated with normal saline or HGF middle dose as a
background control group. Blood and urine biochemical parameters, renal tissue
morphology, and mRNA and proteins of Wnt/?-catenin signaling pathways were
investigated. The results showed that the quality of the extraction process could
be controlled, and a total of eight major compounds were identified and
quantified. HGF could decrease the level of serum creatinine, blood urea
nitrogen, and urine protein and increase the renal index and creatinine clearance
rate in a dose-dependent manner. HGF also remarkably reduced the
glomerulosclerosis and tubulointerstitial fibrosis by blocking the Wnt/?-catenin
signaling pathway through inhibiting the Wnt1, ?-catenin, transcription factor 4,
and fibronectin 1 expressions, simultaneously measured through mRNA and protein
levels in the remnant kidney. These results suggest that extraction of HGF could
improve remnant renal function and possibly ameliorate glomerulosclerosis and
tubulointerstitial fibrosis by depressing the Wnt/?-catenin signaling pathway.
