RESULTS: A well-resolved and reproducible 2-DE pattern of PBMC was obtained from patients with HBV associated HCC or LC. For HCC, the mean number of protein spots was 1186±43, with an average matching rate of 91.6%, and for LC, the mean number of protein spots was 1013±41, with an average matching rate of 90.2%. Twenty-seven differential proteins were tested by MALDI-TOFMS, and 16 were identified. Of the 16 proteins, 13 were up-regulated in patients with HCC, including heat-shock protein 27, member RAS oncogene family (RAB14), actin, alpha 1 antitrypsin, RNAbinding protein regulatory subunit and so on. By contrast, the levels of proteins such as PDX6, HSPA8 and MnSOD were significantly reduced in HCC patients.

Nucleoprotein is also a major immunogenetic antigen for SARS; however, several tests have shown that N protein had the reactivity with other coronavirus positive sera. It is therefore an advantage of S protein as recombinant target antigen for SARS serum diagnosis compared with recombinant N protein. Moreover, S protein has been shown to be the major antigenic determinant that induces neutralizing antibodies and protective immunity to SARS-CoV, so it is also important in designing SARS genetic engineering vaccine.

Results We obtained a lysogenic bacteriophage MZTP01with clear plaque and 1 mm diameter. Fragment D with 2362bp (Genebank No. AY639599) was obtained after the phage DNA hydrolyzed by HindⅢ/EcoRⅠ. Among fragment D, the pep gene with molecular weight of 47 kDa and length of 1101bp was cloned and expressed. Recombinant M15 (pQE30pep) was built and overexpressed in Escherichia coli with a 47kDa clear band. At the same place a clear band was observed by Western blot. Judging from the time course expression, we could conclude that PEP protein produced at 1 hour after induction and then increased gradually. PEP protein was mainly in the form of inclusion body in the recombinant and slowed the growth speed of host. Homologous comparison of PEP protein from phage MZTP01 with other PEPs from BLAST were that phage MZTP01 PEP protein had 100% homologe with that of Escherichia coli K12, and most of others took the similarity in the range between 37%~84%.
