Extensive well-controlled clinical studies performed over the past 5 years have demonstrated a consistent, dose-dependent, statistically significant improvement in the appearance of photodamaged skin after 3-6 months of daily treatment with topical 0.001-0.1% tretinoin cream.

Cancer Chemotherapy and Pharmacology, 1979
The early and recent investigations in the field of retinoids and cancer are reviewed. The retinoids, including natural vitamin A compounds and their synthetic analogs, present a new class of substances exerting a prophylactic and a therapeutic effect both in certain experimental tumor models and in certain clinical conditions of preneoplastic and ...

Retinoids are a group of naturally occurring and synthetic compounds with vitamin A-like biological activity. They play an important role in vision, reproduction, growth, and epithelial cell differentiation. Recent discoveries of specific retinoid cellular binding proteins and nuclear receptors have led to a better (although not complete) understanding

The observation that topical retinoic acid could attenuate wrinkles and other features of skin photoageing has projected this molecule into the media spotlight. Behind this effect are in fact major basic biological issues related to the role of retinoids in tissue maintenance and their possible interference with the molecular biology of cellular ageing.

Retinoid Specificity of Interphotoreceptor Retinoid-Binding Protein
Biochemistry, 1994Interphotoreceptor retinoid-binding protein (IRBP), the predominant protein in the interphotoreceptor matrix of retina, has been implicated in transfer of retinoids between retinal pigment epithelium and photoreceptor cells. In this work, the interactions of several retinoids with IRBP were studied in order to clarify whether the protein displays ...

Journal of Chromatography B: Biomedical Sciences and Applications, 1990
This article reviews the determination of retinoic acids and their metabolites (first-generation retinoids), aromatic retinoids (second generation) and arotinoids (third generation) in biological samples. Because of the sensitivity of the retinoids to isomerization and oxidation, special care has to be taken from sample collection and storage ...

European Urology, 1999
Over several decades, in vitro experimental studies have demonstrated that retinoids effect the process of carcinogenesis and tend towards the alteration of cells back to more normal differentiation. This hypothesis has formed the basis of several chemopreventive studies in breast cancer, cervical cancer, head and neck cancer and lung cancer ...

The retinoids are synthetic derivatives of vitamin A. Isotretinoin (13-cis-retinoic acid) is now being widely used in the United States for severe acne and etretinate is available in Europe and other countries for psoriasis. These drugs are also effective for a number of other skin diseases.

Retinoids, chemicals that have vitamin A activity, have become important therapeutic agents for a variety of cutaneous disorders, including acne. This paper reviews the history of retinoid use in acne, including retinol, topical tretinoin, topical and systemic isotretinoin, systemic etretinate, and new investigational retinoid molecules.
