Tanshinone IIA(TAN IIA)是其活性成分,可以在体外抑制急性白血病细胞系的生长,尽管该机制尚不清楚。 CCK-8测定法和BRDU染色用于评估细胞增殖能力。使用QRT-PCR检测MiR-497-5p表达水平,使用QRT-PCR检测到蛋白质表达。 class =“ sub_abstract_label”>结果: 我们报告说,棕褐色可以抑制细胞的增殖,诱导细胞周期停滞,并促进急性骨髓性白血病(AML)细胞中的细胞凋亡。细胞通过miR-497-5p的mir-497-5p观察到相同的作用,我们证明了棕褐色IIA可以通过上调mir-497-5p的表达来抑制Akt3的表达。IA显然逆转了在恶劣条件下用miR-497-5p抑制剂治疗的作用。 In turn, PCNA expression was increased and cleaved Caspase-3 was suppressed, which contributed to the growth of AML cells. Conclusions: Our results showed that Tan IIA could inhibit cell proliferation in AML cells through miR-497-5p-mediated AKT3 downregulation途径。
