ABSTRACT
Objective:
To construct the eukaryotic expression vector of open reading frame of KH gene(KH-ORF),an unknown gene obtained from K562 cells,and investigate its function.Methods:
The KH-ORF cDNA was cleaved from plasmid expression vector cut with the same restriction endonucleases.pCI-KH-ORF,the pGEM-T-easy-KH-ORF with EcoRI and SalI and subcloned into the pCl-neo mammalian recombinant expression plasmid,was transfected into K562 cells with liposome and screened by G418.KH-ORF expression was tested by RT-PCR.The effect of expression product on cell proliferation was tested by growth-curve and LDH detection.Results:
KH-ORF was expressed in K562 cells.The effects of increased proliferation were significant.Conclusion:
The product of KH-ORF may be a functional protein that is related to the proliferation of K562 cells,and KH gene may be a functional unknown leukemia gene.
