Abstract: Proliferative cutaneous disease states or conditions are treated by administering a polyamine transport inhibitor R-X-L-polyamine wherein R is a straight or branched C10-50 saturated or unsaturated aliphatic, carboxyalkyl, carbalkoxyalkyl, or alkoxy; a C1-8 alicyclic; a single or multiring aryl substituted or unsubstituted aliphatic; and aliphatic-substituted or unsubstituted single or multiring aromatic; a single or multiring heterocyclic; a single or multiring heterocyclic aliphatic; an aryl sulfonyl; X is —CO—, —SO2—, or —CH2—; and L is a covalent bond or a naturally occurring amino acid, lysine, ornithine, 2,4-diaminobutyric acid, or pharmaceutically acceptable salts thereof or prodrug thereof, and a polyamine biosynthesis inhibitor.

Abstract: There is disclosed cDNA sequences and polypeptides having the enzyme CDP-diacylglycerol synthase (CDS) activity. CDS is also known as CTP:phosphatidate cytidylyltransferase. There is further disclosed methods for isolation and production of polypeptides involved in phosphatidic acid metabolism and signaling in mammalian cells, in particular, the production of purified forms of CDS.
