Abstract: The invention is a method of inhibiting cancer growth, by inhibiting cellular proliferation, invasiveness, or metastasis, or by inducing cytotoxicity against cancer in mammals. The method employs 6-demethyl-6-deoxy-4-de(dimethylamino)tetracycline (CMT-3) and other functionally related chemically modified, preferably non-antibacterial, tetracycline compounds to inhibit cancer growth. The method is particularly effective to inhibit the establishment, growth, and metastasis of solid tumors, such as tumors derived from colon cancer cells, breast cancer cells, melanoma cells, prostatic carcinoma cells, or lung cancer cells.

Abstract: Provided for use in site-directed chemotherapy are compositions comprising chemotherapeutic agents targeted to either arrested metastatic cells via a cell-surface marker associated with metastasis; or are targeted to type 1 endothelial cells of the tissue comprising the organ site at which metastatic cells arrest such that (a) any arrested metastatic tumor cells are then exposed to the chemotherapeutic agent, and/or (b) the endothelial cells are altered thereby inhibiting the ability of the metastatic tumor cells to arrest, survive or proliferate in that site. Also provided are methods of site-directed chemotherapy of metastatic cells of non-lymphoid tumor origin. Site-directed chemotherapy comprises introducing a therapeutically effective amount of a chemotherapeutic agent directly into a vascular access of the organ having, or suspected of having, arrested metastatic cells thereby concentrating the therapy in the prometastatic territories of the treated organ.

Abstract: An alkanethiol monolayer membrane is formed on a substrate having an Au layer using Au--S bonding, and a second layer constructed by a monolayer lipid membrane is formed on its surface to form a BLM. A gel layer is formed using agarose on the side of the BLM having the second monolayer lipid layer. In addition, a polymer layer is formed using the amino acid poly-L-lysine between the surface of the monolayer lipid membrane and the gel layer to immobilize the BLM. The use of this supporting constitution for holding and immobilizing the membrane extends the life-span of the BLM, while the gel layer keeps the electrolyte solution required for maintaining flexibility of the membrane and activating protein on the surface of the BLM. In addition, a BLM having a life-span of one month or more is obtained by arranging a membrane supporting portion that minimizes lifting of the membrane molecules due to buoyancy above the BLM arranged upright in an aqueous system.

Abstract: The invention is directed to inter alia two related but self-sufficient improvements in conventional display methods. The first improvement provides methods of enriching conventional display libraries for members displaying more than one copy of a polypeptide prior to affinity screening of such libraries with a target of interest. These methods can achieve diverse populations in which the vast majority of members retaining full-length coding sequences encode polypeptides having specific affinity for the target. In a second aspect, the invention provides methods of subcloning nucleic acids encoding displayed polypeptides of enriched libraries from a display vector to an expression vector without the need for clonal isolation of individual members. These methods result in polyclonal libraries of antibodies and other polypeptides for use, e.g., as diagnostic or therapeutic reagents.
