Gender-related seasonality of human platelet phenolsulfotransferase activity.
This study focused on the investigation of the possible effect of gender and season on the activity of the thermolabile and thermostable forms of platelet phenolsulfotransferase (PST) in a group of 23 healthy, drug-free volunteers of both sexes. The results showed a different seasonal profile of PST activity in men and women: in men, PST seasonal rhythms revealed a shallow profile with higher values in both the spring and summer than in the autumn. Conversely, in women, the PST seasonality showed a profile consisting overall of a main peak in the summer. Also, significant gender-dependent correlations were found between the photoperiod length and PST values. Our findings should stimulate further investigation into gender-dependent molecular mechanisms underlying the regulation of the metabolism of endogenous and xenobiotic agents, such as monoamines and phenols, which are the substrates of PST.
