    摘要： Methods and compositions for the development of effective cancer therapies using mitotic inhibitors which have limited general toxicity to normal, non-cancerous cells and tissues are provided. The methods and compositions utilize cytotoxic compounds comprised of a cell-binding agent (e.g., antibodies) conjugated to an anti-mitotic compound (e.g., maytansinoids). The invention further provides antibodies which are substantially incapable of inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC), thereby ensuring that the therapeutic effect is mediated primarily by the anti-mitotic component of the cytotoxic compound, rather than by indirect cell killing via ADCC and/or CDC. The antibodies of the invention further are capable of differentiating between polypeptide antigens which are more highly expressed on proliferating cancer cells as compared to proliferating non-cancer cells.

    摘要： A method for controlled production of a desired mature protein in a vertebrate host cell through the use of a polycistronic expression vector, which contains sequences coding for the desired protein and a secondary protein, is described. Both coding sequences are governed by the same promoter and are separated by translational stop and start signal codons. The expression of the secondary sequence effects control over the expression of the sequence coding for the desired protein, and the secondary protein functions as a marker for selection of transfected cells.
