人的身体,由于紫外线和致癌物质等被基因的破坏,总是通过具有一定“修理店”作用的蛋白质进行恢复。然而,制造这种蛋白质的基因只要有一处“错字”,便会造成失去修复功能的疾病。在最近于日本东京市召开的日法癌教学研究会上,日本大阪大学细胞工程中心的田中龟代次副教授和冈田善雄教授等宣称,他们用很少引起遗传疾病患者的基因,查明了成为这种关键的“错码”的地方在那里。这种修复功能障碍疾病,尽管是很年轻的人,也可像老年人那样,被老人斑等侵入肌肤,易患与皮肤癌有关的“色素性干皮症”。据说,这是修复基因不能修复因紫外线被破坏的蛋白质的原因。
The human body, due to the destruction of genes such as ultraviolet rays and carcinogens, is always restored through proteins that have a certain “repair shop” role. However, as long as there is a “typo” in the genes that make up this protein, it can cause diseases that have lost repair function. At the recent Japan-France Cancer Research Conference held in Tokyo, Japan, professors Tanaka Koto and Professor Okada of the Cell Engineering Center of Osaka University in Japan declared that they used the genes of patients with rare genetic diseases to find out There is a place where this key “error code” is. This kind of repair dysfunction disease, although it is a very young person, can also be invaded by age spots and the like as in the elderly, and is susceptible to “pigmented dry skin disease” related to skin cancer. It is said that this is why repair genes cannot repair proteins that are damaged by ultraviolet light.
