Then, 24 hours later, they tested the samples to detect whether specific hair-growth proteins in the cells had changed at all.
24小时后,研究人员测试了样本,以检测细胞中和头发生长有关的特定蛋白质是否发生了变化。
Researchers found the presence of PM10 and diesel particulate decreased levels of the protein responsible for hair growth – beta-catenin – and morphogenesis.
研究人员发现,PM10和柴油颗粒物的存在降低了促进头发生长的蛋白质——连环蛋白的水平,阻碍了形态发生。
morphogenesis[,mɔrfə'dʒɛnəsɪs]: n. [胚] 形态发生
Morphogenesis is the biological process that causes an organism to develop its shape. It is one of three fundamental aspects of developmental biology.
形态发生是导致有机体成形的生物过程,是发育生物学的三个基本方面之一。
According to the study, the levels of three other proteins which are responsible for hair growth and hair retention – cyclin D1, cyclin E and CDK2 – were also decreased.
研究指出,促进头发生长、防止脱发的其他三种蛋白质——细胞周期蛋白D1、细胞周期蛋白E和细胞周期素依赖性激酶2——水平也下降了。
This meant that the greater the level of pollutant, the greater the decrease in proteins was found. This is one of the first studies to look at the link between pollution and baldness.
