We have examined the endogenous nuclease activity of the liver of intact, castrated and testosterone-treated mice of different ages. Both Mg2+- and Ca2+-dependent endogenous nuclease activities decline in old age. Withdrawal of the hormone increases nuclease activity in the immature and young. However, testosterone administration prevents the digestion of nuclei to different extents in all ages. These findings suggest a possible protective role of testosterone in the cleavage of liver chromatin by endogenous nucleases during the aging of mice.
