Abstract: This disclosure provides ASCT2-binding molecules, e.g., anti-ASCT2 antibodies, and antigen-binding fragments thereof. In certain aspects, the ASCT2-binding molecules are conjugated to cytotoxic drugs, e.g., ASCT2 antibody-drug conjugates (ADCs). In certain aspects, the anti-ASCT2 antibodies and fragments thereof can be hybridoma-derived murine monoclonal antibodies, and humanized versions thereof. In certain aspects, the ASCT2-binding molecules bind specifically to cells expressing ASCT2, and in some instances, are internalized into the cells. In addition, this disclosure provides compositions and methods for diagnosing and treating diseases or disorders characterized by ASCT2 overexpression, e.g., certain types of cancer. In a particular embodiment, the disclosure provides methods for treating cancer using ASCT2 ADCs.

Abstract: This invention provides nucleic acid sequences, vectors and host cells comprising regulatory regions associated with various promoters including a cyclin D1 promoter, a CD40L promoter, three HBV promoters (core, pre-S1 and HBV-X), a vancomycin-resistant enterococci (VRE) promoter, an androgen receptor promoter, a Her2 promoter, and ?-lactamase promoter. The invention further provides methods of regulating gene expression comprising the regulatory regions of such promoters.

Abstract: The invention provides a novel nucleic acid binding assay, which is useful for assessing the sequence-dependence of the binding of ligands to nucleic acid molecules, as well as for determining the affinity of the binding interaction. The invention also provides a selection method based on this nucleic acid binding assay. This selection method allows co-selection of ligands and the nucleic acid molecules that they bind. Additionally, the invention provides kits that can be used for carrying out the methods of the invention.
