| Research Abstract |
Established primary cultured oligodendrocytes in each stage were exposed to UV(0-10 J/ m^2). Afterwards, they were stained by anti-MBP, GFAP, and 6-4PP antibodies. Fluorescence amount of 6-4PP per fluorescence amount of nuclear DNA was calculated just after UV radiation and at each repair point, and the change of repair activity along with the differentiation stages was studied. NER activity was observed to be changed by differentiation. Furthermore, we investigated the mechanism of the difference of repair activity, and found the difference of the expressions of repair-associated proteins such as PCNA, indicating the difference of the expressions of repair-associated proteins might lead to the difference of repair activity.
