Abstract:
The expression of the c-fos and c-myc oncogenes was investigated by dot blot analysis of total RNA extracted from biopsies of normal skin and psoriatic lesions. Densitometric analysis revealed 6.3 fold and 8.6 fold evevation respectively of c-fos and c-myc oncogenes mRNA levels in severe psoriasis compared to normal skin, and 1.5 fold and 1.6 fold elevation respectively of c-fos and c-myc oncogenes mRNA levels in mild psoriasis compared to normal skin. The ratio of c-fos/c-myc transcripts in normal skin and mild psoriasis was constant compared to that in severe psoriasis. The maintenance of a constant ratio of c-fos/c-myc is believed to be closely related to ordered cell growth and the ratio of c-fos/c-myc transcripts in severe psoriasis suggests a disordered pattern of cellular differentiation. We be1ieve that overexpression of these oncogenes is related to the pathogenesis of psoriatic epidermal hyperplasia.
