  5. In order to further investigate the role of axudl in human tumor carcinogenesis and the potential association between the axudl gene expression status and the stimulation of transforming growth factor beta in human cancers, the present study was performed in three aspects as follows : ( 1 ) cloning full length enconding region cdna of axudl and construction of eukaryotic vector that expression the fusion protein of axud1 and influenza virus hemagglutin ha epitope tag ; ( 2 ) exploring the time and dose effects of tgf - 1 on the expression - of axudl gene in hepg2 hepatoma cells and spc - a1 lung carcinomas cells, and studying the effects of overexpression of axud1 on the expression of cell cycle and apoptosis related protein in hepg2 hepatoma cells ; ( 3 ) construction and expression of human axudl in e. coli m15. the following main results and conclusions can be obtained from the present study : 1. the full length ecnoding region of human axudl cdna from human peripheral blood lymphocytes was successfully cloned using one step rt - pcr method, and constructed into a eukaryotic expression vector which can be expressed a ha - axud1 fusion protein with axud1 and influenza virus hemagglutin ha epitope tag. the recombinant plasmid was identified by polymerase chain reaction, restriction endonuclease maping and sequencing, this expression vector might be instrumental to further study the function of axud1 protein in tumor cells
