Abstract:
The levels of macrophage migration inhibitory factor (MIF), a proinflammatory and carcinogenic cytokine, were significantly higher in the sera from patients with hepatocellular carcinoma (HCC; 25.6+/-15.3 ng/ml, n=55) and liver cirrhosis (LC; 18.9+/-10.7 ng/ml, n=26) compared with sera from patients with gastrointestinal cancer (6.8+/-7.5 ng/ml, n=29) and normal controls (5.6+/-1.2 ng/ml, n=45; P<0.01). Hepatocytes from patients with LC and HCC, but not from chronic hepatitis, expressed very high levels of MIF. A possible association between overexpression of MIF and hepatocarcinogenesis is suggested.
