ABSTRACT
This study was aimed to explore the expression level of the unknown cgi-100 gene in human leukemia K562 cells treated with matrine, and to investigate effect of cgi-100 on proliferation of K562 cells. The expression level of cgi-100 was detected by RT-PCR in K562 cells before and after being treated with matrine; pIRES2-EGFP/cgi-100 eukaryotic expression vector was constructed by DNA recombinant technique and was introduced into K562 cells by liposome-mediated DNA transfection. The cgi-100 gene expression level, growth-curve, and cell cycle of the modified K562-cgi-100 cells were detected by RT-PCR, Trypan blue staining and FCM. Morphological changes were observed under the optical and electron microscopes. The results indicated that the expression level of cgi-100 decreased in K562 cells treated with matrine. Heterochromatin decreased, euchromatin and the proportion of S phase in K562-cgi-100 cells increased, and cell proliferation enhanced. It is concluded that the expression of cgi-100 mRNA decreased in a dose- and time-dependent manner in the K562 cells treated with matrine and over-expression of cgi-100 elevates the proliferation and the immaturity level of K562-cgi-100 cells.
