Isotretinoin treatment upregulates the expression of p53 in the skin and sebaceous glands of patients with acne vulgaris.

The transcriptomic regulation induced by isotretinoin (13-cis retinoic acid) is still a matter of debate as short-term exposures of immortalized sebocytes with isotretinoin produced conflicting results. Based on translational evidence, it has been hypothesized that oral isotretinoin treatment upregulates the expression of the transcription factor p53. Twenty-five patients suffering from acne vulgaris were treated with isotretinoin (0.

Potential role for microRNA-16 (miR-16) and microRNA-93 (miR-93) in diagnosis and prediction of disease progression in mycosis fungoides in Egyptian patients.

Mycosis Fungoides (MF) is the most common type of cutaneous T-cell lymphomas. Early stage patients are treated with topical therapies and have normal life expectancy whereas patients with advanced disease encounter frequent relapses and have a five-year survival rate that does not exceed 15%. The aim of the present study was to characterize the expression of microRNA-16 (miR-16) and microRNA-93 (miR-93) in early and advanced cases of MF in relation to the clinicopathological parameters.

Effect of oral isotretinoin on the nucleo-cytoplasmic distribution of FoxO1 and FoxO3 proteins in sebaceous glands of patients with acne vulgaris.

Oral isotretinoin is the most effective anti-acne drug with the strongest sebum-suppressive effect caused by sebocyte apoptosis. It has been hypothesized that upregulation of nuclear FoxO transcription factors and p53 mediate isotretinoin-induced sebocyte apoptosis in vivo. It is the aim of our study to analyse the distribution of the pro-apoptotic transcription factors FoxO1 and FoxO3 in the nuclear and cytoplasmic compartments of human sebocytes in vivo before and during isotretinoin treatment of acne patients.
