Cellular adhesion regulatory molecule (CMAR) enhances the adhesiveness of cells to collagen and laminin and is considered to be a candidate anti-oncogene. The purpose of the present study was to investigate the relationship between the expression of CMAR and clinical features of hepatocellular carcinoma (HCC). Small amounts of liver tissue were obtained from HCC and non-cancerous portions of the liver in 29 patients and from normal liver in seven patients with metastatic liver tumour by biopsy under ultrasound guidance. RNA was extracted with acid guanidinium thiocyanate-phenol-chloroform. Expression of CMAR was assessed by quantitative PCR using beta-actin as an internal standard. A 4 b.p. insertion polymorphism at nucleotide 241 of the CMAR coding region was then investigated using extracted RNA to assess the relationship between the expression of variant mRNA of CMAR and HCC carcinogenesis. The relative expression of CMAR was significantly reduced in HCC compared with non-cancerous and normal livers and had a relationship with certain clinical background factors. The reduced expression of CMAR was thought to be closely associated with the progression of HCC. However, the 4 b.p. insertion polymorphism pattern of CMAR was the same between HCC and non-cancerous liver in all cases in which it was found. These results suggest that progression of HCC may be predicted based on the relative expression of CMAR.
