Oxidations changing with aging in male rat cohort. A Experimental flow chart of rat cohort. B and C open-search, unsupervised cluster analyses of both all identified modifications and all oxidations state oxidations in old group is obviously different from the low age groups. D 15 oxidations show an upwards trend with aging. E 8 oxidations are differential in old from others, and they are almost linear increasing with aging using two tailed tests. Data are presented as mean ± SD. As the number of labels increases, the significance increases. (*p <0.05, **p < 0.01, ***p < 0.005, ****p < 0.001)
