已有许多文章论述紫外线(UV)的照射不论是在体内还是在体外都具有诱导色素生成的能力,但细胞内有关该过程的反应情况却很少报道。最近,作者发现经照射后,DNA的修复增加,将会增强UV诱导的黑色素化作用。而且,一些小的DNA片段, There are many articles discussing the ultraviolet (UV) radiation whether in vivo or in vitro have the ability to induce pigment production, but intracellular response to the process is rarely reported. Recently, the authors found that increased DNA repair after irradiation will enhance UV-induced melanization. Moreover, some small DNA fragments,
