摘要:
For the first time, certain retinoids with a side chain terminal CH.sub.2 OH group or ester or ether thereof or aldehyde rather than a side chain terminal COOH group and substitution at the 4-position have been indicated to bind to nuclear receptors and to be biologically active in inducing cell differentiation of normal and tumor cells. These compounds activate gene expression through binding to nuclear receptor proteins. These compounds induce differentiation in normal and cancer cells and are useful for treating leukemias, and lymphomas, squamous cell carcinomas, deep (cystic) acne, psoriasis and photodamaged or aging skin. These compounds have stability and in vitro half-life advantages over and solubility differences from all-trans-retinoic acid and activity advantages over 13-cis retinoic acid.

摘要:
The present invention relates to retinol dehydratase, the enzyme which synthesizes the retro-retinoid anhydroretinol in the Spodoptera frugiperda insect cell line Sf-21, as well as the DNA molecule encoding that enzyme. The DNA molecule can be incorporated in a DNA expression system and a host for recombinant production of anhydroretinol dehydratase. The isolated retinol dehydratase protein or polypeptide of the present invention can be combined with a pharmaceutically-acceptable carrier or used alone for administration to mammals, particularly humans, for preventing cell growth and/or uncontrolled cell growth in cells which are growth dependent on retinol and/or 14 hydroxy-4, 14-retro-retinol.
