Abstract Studies were conducted to assess the normal tissue-associated levels of pristane (2,6,10,14-tetramethyl-pentadecane) in Copenhagen rats during ontogeny and adult life and to address whether or not dietary pristane can be adsorbed from the gut and disseminated throughout the body. During the course of this study the possible effects of dietary pristane on chromatin conformation of lymphoid cells were also examined by flow cytometry. The data indicated that 1) pristane crossed the placenta and accumulated in fetal tissues, 2) neonates were exposed to pristane via the colostrum, 3) there were significant increases in the amount of tissue-associated pristane in young adults and subsequent redistribution of the pristane to the muscle and adipose tissues in older rats and 4) after dietary exposure, significantly elevated levels of pristane were associated with the tissues and concomitant changes in chromatin conformation were observed. Collectively, these results suggest that pristane was adsorbed from dietary sources, disseminated to the tissues and exerted a transient, yet marked effect on chromatin of lymphoid cells in rats.
