Previous studies have demonstrated that the nuclear factor κB (NF-κB) pathway is involved in promoting cell proliferation. To further explore the regulatory branches and their sequence in the NF-κB pathway in the promotion of hepatocyte proliferation at the transcriptional level during rat liver regeneration, Rat Genome 230 2.0 array was used to detect the expression changes of the isolated hepatocytes.
To study the effect of fructus polygoni orentalis extract (EFPO) on liver regeneration and proliferation of bone marrow cells on rat model of partial hepatectomy, EFPO was extracted, and 60 adult male Wistar rats were divided randomly into 6 experimental groups. Rats were treated with intergastric administration (ig) with EFPO daily. All rats were euthanized 7 days after administration, and the livers and bone marrow cells were collected. The levels of taxifolin and quercetin in EFPO were 1.238 and 0.381 mg/g, respectively.
