Objective To clone the human gene of Hepatitis B virus e antigen binding protein 1 (HBEBP1), which was screened with yeast two-hybrid system and bioinformatics techniques, to construct prokaryotic expression vector of pET-32a(+)-HBEBP1, and to induce the expression of recombinant protein in E. coli BL21. Methods The DNA fragment of HBEBP1 of about 372bp was amplified by reverse transcription PCR (RT-PCR), in which the mRNA was taken from HepG2 cells as the template, and cloned into pGEM-T vector. After restriction enzyme digestion identification and sequencing, the correct target DNA fragment was inserted into inducible prokaryotic expression vector pET-32a(+) and then transformed into competent E. coli BL21. By restriction enzyme digestion and PCR, the positive transformed clones were identified and induced with IPTG to obtain fusion protein. The HBEBP1 fusion protein was analyzed by Western blotting hybridization. Results The 372bp DNA fragment of HBEBP1 was amplified by RT-PCR. The recombinant expression vector pET-32a(+)-HBEBP1 was constructed successfully. After transformation with pET-32a(+)-HBEBP1 and induction with IPTG, the recombinant target protein of about 33kD was obtained, which was consistent with our anticipation. Western blotting assay showed that the protein had good specificity. Conclusions The recombinant prokaryotic expression vector pET-32a(+)-HBEBP1 is constructed, and the HBEBP1 gene is cloned successfully. The HBEBP1 fusion protein could be expressed in prokaryotic expression system of E. coli. These results lays a foundative for studying the immunogenicity and the biological characteristics of the HBEBP1 protein.

AIM:To investigate the expression and the significance of VEGF-C/D in rat cornea after alkali burning as well as the role of lymphangiogenesis in the high-risk corneal transplantation rejection.
●METHODS:The model of alkali burn corneal was made. Different times corneas were taken to electron microscope for vascularization, and examined the expression of VEGF-C/D and VEGFR-3 in l, 3, 5, 7, 14, 28d. The other rat cornea after alkali burn were divided into four parts to penetrate keratoplasty, containing only blood vessels in the cornea ( group A ) , angiogenesis and lymphangiogenesis ( group B ) , lymphangiogenesis degenerating period ( group C ) , angiogenesis degenerating period ( group D ) . ln addition, there are also normal groups ( group N ) to compare the Rl values and survival time of corneal graft.
●RESULTS: Electron microscopy showed that, when the first 7d rat cornea appeared neovascularization after alkali burn, but not lymphangiogenesis. The occurrence of new blood vessels and lymphatic in 2wk. There were no obvious lymphangiogenesis in 5wk and the angiogenesis gradually subside in 8 wk. The expression of VEGF-C/D and VEGFR-3 in the corneas of rats were up-regulated in the third days after the injury, and reached its peaks at 5d. The average survival time of group N, A, B, C, D were (14.25±0.62)d, (9.35±1.02)d, (5.06±1.13)d, (8.71±0.83) d, (9. 44±1. 05)d after transplant cornea. Compared to the rest of the group, group B plant average survival time significantly shortened (P<0. 05), while compared with group B, the survival time of A, C, D groups were significantly longer (P<0. 05).
● CONCLUSION: VEGF - C/D and VEGFR - 3 are expressed significantly after corneal alkali burn. New lymphatic vessels can accelerate high - risk corneal transplantation immune rejection.
