PMA特异性抑制K562细胞BCR/ABL和Fyn mRNA的表达
PMA specifically inhibits mRNA expression of BCR/ABL and Fyn in K562 cells
摘要
Abstract
ADM: To study the effects of phorbol 12 — myristate 13 — acetate ( PMA ) on the mRNA expression of BCR/ABL and Fyn in K562 cells, and to explore their relationship. METHODS: The K562 cells were stimulated by PMA at a series of concentrations ( 1 ~ 250 μg/L ) for 24 h, and the mRNA expression levels of BCR/ABL and Fyn in K562 cells were detected by real - time fluorescence quantitative PCR . The relative changes of both mRNA expression were measured using 2 -ΔΔCt formula. RESULTS: PMA significantly inhibits the mRNA levels of BCR/ABL and Fyn in a dose - dependent manner, and the correlation of these inhibitory effects were significant. Compared with gene Molt - 4 cells, the inhibition by PMA was specific for K562 cells. The K562 cells were induced to differentiate to be pseudopodium -like ceUs. CONCLUSION: The PMA downregulates the mRNA level of Fyn by inhibiting BCR/ABL fusion gene.关键词
