ABSTRACT
BACKGROUND:
Many liver cancer stem cel markers have been found in liver cancer tissues and cel lines such as CD133, acetaldehyde dehydrogenase (ALDH), CD90, CD44, EpcAM, CD13, OV6, K19, c-kit and ABCG2. Of them, CD133, CD90 and CD44 have been shown to be strongly associated with the recurrence and metastasis of liver cancer.OBJECTIVE:
To explore the dynamic changes of liver cancer stem cel markers and inflammatory factors during the induction of liver cancer in rats and their correlation.METHODS:
Diethyl nitrosamine solution was given to Sprague-Dawley rats for 24 hours to induce rat models of liver cancer. Rats that were given common water were considered as the healthy control group. RESULTS ANDCONCLUSION:
Immunohistochemical staining revealed that Kupffer cels-related ED2 expression showed a gradual increase in the model group. Compared with the healthy control group, ED2 expression was significantly higher at 12, 16, 20 and 24 weeks after induction in the model group (P 0.05). During induction, no significant change was found in other liver cancer stem cel markers (P> 0.05). During the induction, tumor necrosis factor α, transforming growth factor β, MCP-1 and interleukin-6 expression levels were significantly increased (P 0.05). Pearson correlation analysis demonstrated that MCP-1, transforming growth factor βand interleukin-6 expression levels were significantly positively correlated with CD90 expression (P < 0.05). These findings suggest that partial inflammatory factors released from Kupffer cels have a certain correlation with liver cancer stem cels. Kupffer cels can promote the occurrence of liver cancer.
