Abstract:Objective To investigate the correlations of TLR4, MyD88 and NF-κB expressions with clinicopathological features in hepatocellular carcinoma. Methods Patients with hepatocellular carcinoma were chosen and their serum, hepatocellular carcinoma tissues and paracancerous tissues were collected, and serum was also collected from healthy volunteers. The mRNA levels of TLR4, MyD88 and NF-κB in hepatocellular carcinoma tissues and serum content of AFP, TK1, GP73 and ASPH were detected. Results The mRNA levels of TLR4, MyD88 and NF-κB in the hepatocellular carcinoma tissues were significantly higher than those of the paracancerous tissues. The mRNA levels of TLR4, MyD88 and NF-κB in the hepatocellular carcinoma tissues of the patients with TNM stage III-IV, poorly- differentiated or undifferentiated cancer and lymph node metastasis were significantly higher than those in the hepatocellular carcinoma tissues of the patients with TNM stage I-II, well-moderately differentiated cancer and no lymph node metastasis. The serum content of AFP, TK1, GP73 and ASPH in the hepatocellular carcinoma patients was significantly higher than that in the control group and positively correlated with TLR4, MyD88 and NF-κB mRNA levels. Conclusions In hepatocellular carcinoma, TLR4 pathway function is enhanced and closely related to clinicopathological stage and content of serum tumor markers.
