INTRODUCTION
Acne is one of the most common skin disorders treated by dermatologists and other health care providers. It is a chronic inflammatory skin condition.
Several drugs are used in the treatment of acne vulgaris, Isotretinoin (13-cis-retinoic acid) is the most effective drug used in the treatment of moderate to severe acne vulgaris.
Treatment with isotretinoin results in sebaceous glands shrinkage and reduced sebum production.
Many authors had suggested that the main role of systemic isotretinoin is sebocyte apoptosis in different ways. This apoptosis was hypothesized to be due to increased p53 expression.
AIM OF THE WORK
The aim of this work was to detect the effect of oral isotretinoin on the expression of p53 in tissues by immunohistochemistry, ELISA and PCR through taking skin biopsies before and after isotretinoin treatment in patients with acne vulgaris.
