Selected Inflammatory and Metabolic Markers in Psoriatic Patients Treated with Goeckerman Therapy
We have previously shown that benzo[a]pyrene (B[a]P) administrated at extremely low dose can cause weight gain in mice and that the increase in adipose tissue mass is due to inhibition of beta-adrenergic stimulation of lipolysis. Moreover we have suggested that in addition to its endocrine properties, adipose tissue act as a reservoir for many chemical carcinogens including Polycyclic Aromatic Hydrocarbons (PAHs). In this paper we show that B[a]P as well as the two C4 PAHs, pyrene and phenanthrene can bioaccumulate into adipocytes in a similar manner, but that at the difference of B[a]P, have no impact on epinephrine-induced lipolysis. On the basis of this ex vivo study, we therefore suggest that B[a]P may play a central role in carcinogenesis not only by inducing cancer through its mutagenic properties, but also by increasing the bioaccumulation capacity of the adipose tissue mass.
