Abstract: Chronological aging of human skin can be delayed with the topical application of an MMP inhibitor, preferably a retinoid (an indirect MMP inhbitor); retinoids also normalize procollagen biosynthesis. Chronological aging, or natural aging, is evidenced in elderly (80+ years old) skin by increased MMP levels and decreased procollagen levels when compared with younger individuals. Prophylactic treatment of not yet chronologically-aged skin with a retinoid both inhibits degradation of dermal collagen and restores procollagen synthesis. Biopsied sections from elderly skin show that a single treatment of chronologically-aged skin with a retinoid can increase epidermal thickness, improve the dermal collagen density, and promote the formation of rete pegs and dermal papillae. Such benefits are helpful in preventing bruising, tearing, and ulceration of elderly skin. Accordingly, prophylactic treatment begun much earlier in life with an MMP inhibitor and/or a retinoid delays the onset of such symptoms.

Abstract: Aryl-substituted and aryl and (3-oxo-1-propenly)-substituted benzopyran, benzothiopyran, 1,2-dihydroquinoline, and 5,6-dihydronaphthalene derivatives have retinoid negative hormone and/or antagonist-like biological activities. The invented RAR antagonists can be administered to mammals, including humans, for the purpose of preventing or diminishing action of RAR agonists on the bound receptor sites. Specifically, the RAR agonists are administered or coadministered with retinoid drugs to prevent or ameliorate toxicity or side effects caused by retinoids or vitamin A or vitamin A precursors. The retinoid negative hormones can be used to potentiate the activities of other retinoids and nuclear receptor agonists. For example, the retinoid negative hormone called AGN 193109 effectively increased the effectiveness of other retinoids and steroid hormones in in vitro transactivation assays. Additionally, transactivation assays can be used to identify compounds having negative hormone activity.

Abstract: A polypeptide is identified as being functionally included in a signal transduction pathway having a biological effect. Contemplated polypeptides are different from a retinoic acid receptor, a retinoid X receptor, or a cellular retinoic acid binding protein; however, binding of the retinoid or retinoid metabolite leads to a modulation of the biological effect. In particularly contemplated methods, a retinoid or retinoid metabolite is administered to a cell or mammal in a concentration effective to modulate the biological effect.
Abstract: The present invention provides compositions and methods for treating an animal, preferably a human, suffering from or predisposed to a physical disorder by administering an effective amount of a composition comprising at least one RAR antagonist, preferably an RAR&agr; antagonist, and at least one RXR agonist. The combination of an RXR agonist, which has no therapeutic effects alone, with an RAR antagonist allows the use of lower doses of the RAR antagonist than were previously thought to be efficacious; this approach obviates many of the undesirable physiological side-effects of treatment with RAR antagonists.
