Abstract
AIM: To investigate the expression of cell-cycle related proteins p53, p21, STAT3 and Cyclin D1 in the cirrhosis phase of hepatocarcinoma in a rat model carrying abnormal savda.
METHODS: According to the theory of Uyghur medicine, a rat model of abnormal savda was created, and on this basis, DEN was used to induce cirrhosis to result in a rat model of hepatocarcinoma carrying abnormal savda. Liver specimens were taken to detect the expression of p53, p21, STAT3 and Cyclin D1 by immunohistochemistry.
RESULTS: Compared with normal control rats, the expression levels of p53, p21, STAT3 and Cyclin D1 were significantly up-regulated in rats with simple hepatocellular carcinoma and those with hepatocarcinoma carrying abnormal savda (P < 0.01). Compared with rats with simple hepatocellular carcinoma, the expression levels of p53, p21, STAT3 and Cyclin D1 were significantly higher in rats with hepatocarcinoma carrying abnormal savda (P < 0.05)
CONCLUSION: Abnormal savda may up-regulate the expression of p53, p21, STAT3 and Cyclin D1 and affect cell cycle progression, thus accelerates the occurrent and development of hepatocirrhosis.
