Cell culture and SDS-polyacrylamide gel electrophoresis (PAGE) methods were employed to analyse the role of human amniotic basement membrane (HABM) in supporting the growth of forebrain neurons and the components of HABM after enzymatic digestion. It was found that HABM treated with heparinase Ⅱ supported the growth of forebrain neurons 150% of that of the untreated HABM control. The results of SDS-PAGE analysis showed that HABM treated with heparinase Ⅱ had collagen-like polypeptides 2?_1 (260kD) and 2?_2 (225kD) reduced and lamininlike peptides (212kD and 200kD) increased; and that HABM treated with heparinase I or collagenase I had laminin reduced. This indicated that laminin is the major component in HABM to promote the growth of forebrain neurons.

To observe whether there is an interaction between hepatitis virus B (HBV) and tumor suppressor p53, plasmid PCMVp53 was transfected or cotransfected with pCMVHBV a (wild type HBV) or PCMVHBV b (mutation type HBV) into the hepatoma cell line 7721 by phosphate calcium precipitation. Apoptosis cells were labeled by annexin Ⅴ FITC and detected by flow cytometry. Another experiment was performed by cotransfecting the cells with reporter plasmid p21 luc in each group mentioned above, then the luciferase activity was measured. The results showed that the cells transfected by pCMVp53 alone exhibited high luciferase activity and high apoptosis rate. Meanwhile, the luciferase activity and apoptosis rate were further higher in cells cotransfected by pCMVp53 and PCMVHBV a , but remained unchanged in cells cotransfected by PCMVp53 and PCMVHBV b. The results indicated that P53 could induce of 7721 cell apoptosis by activating p21 transcription, and such effect could be enhanced by HBV.
