Methods The expression of CT10 mRNA was detected by using RT - PCR in HCC tissues and the corresponding adjacent non-HCC tissues from 45 HCC patients, among those 3 samples selected randomly from CT10 PCR positive products were sequenced. HLA - A2-restricted CTL epitopes of CT10 was predicted by peptide supermotif prediction combined with quantitative motif. Results CT10 mRNA was detectable in 19/45 (42. 2%) of HCC samples, while the corresponding adjacent non-HCC tissue were all negative in expression of CT10 mRNA. In addition, The DNA sequence confirmed that the RT- PCR products were truly CT10 cDNA. No June 2003 Vol12 No2 relationship was found between the expression of CT10 and demographic and clinical features such as age, sex, tumor size, degree of tumor differentiation, serum α-fetoprotein level and infection of hepatitis B virus or展开更多
