Protein kinase AKT mediates cell proliferation and survival signals, and also contributes to cancer progression. Increased expression and/or activation of AKT is involved in a variety of human cancers. In cells treated with sage or rosemary extract, mRNA and protein expression levels of AKT1 were reduced compared with those of the control cells 48 h after the herbal treatments. We found that terpinolene, a common component of sage and rosemary, markedly reduced the protein expression of AKT1 in K562 cells and inhibited cell proliferation.
蛋白激酶AKT介导细胞增殖和存活信号,也促进癌症进展。AKT表达增加和/或激活与多种人类癌症有关。在用鼠尾草或迷迭香提取物处理的细胞中,草药处理48小时后,与对照细胞相比,AKT1的mRNA和蛋白表达水平降低。我们发现,萜品油烯是鼠尾草和迷迭香的常见成分,可显著降低K562细胞中AKT1的蛋白表达并抑制细胞增殖。
