Abstract: A nucleic acid sequence encoding a variant CYP3A4 gene is provided. Also provided are methods and kits for identifying individuals carrying a variant CYP3A4 gene with a heightened risk of developing or having prostate cancer or a decreased risk for developing treatment-related leukemias and identifying more effective and safer treatment regimes for individuals based upon their CYP3A4 genotype.

Abstract: A composition comprising a magainin peptide or an analogue or derivative thereof, and at least one member selected from the group consisting of a PGLa peptide or analogue or derivative thereof, and an XPF peptide or analogue or derivative thereof. The composition is employed as a pharmaceutical.

Abstract: A composition comprising at least one biologically active amphiphilic peptide, said peptide being an ion channel-forming peptide, and an antibiotic selected from the class consiting of bacitracins, aminoglycosides, penicillins, monobactams, hydrophobic antibiotics, 50-S ribosome inhibitors, antibiotics having a large lipid like lactone ring, and derivatives or analogues thereof. The biologically active amphiphilic peptide and the antibiotic may be administered in amounts effective to inhibit growth of a target cell. The biologically active amphiphilic peptide and antibiotic may potentiate each other.
