Abstract: The present disclosure provides use of CDK16 as a target in preparation of a drug for treating triple-negative breast cancer. It is found through research in the present disclosure that knock down of the CDK16 can significantly inhibit the growth of TNBC xenograft tumors, PDX and PDO. Its mechanism is mainly that the knock down of the CDK16 can inhibit the phosphorylation of PRC1 (T481), prevent formation of spindles in a cell mitotic phase, and make cells unable to divide normally, thereby inhibiting the occurrence, development and metastasis of TNBC tumors. Meanwhile, it is found through research that Rebastinib, a covalent small-molecule inhibitor of the CDK16, shows a very good effect in inhibiting the development of TNBC tumors and is a potential novel drug for the treatment of TNBC.

Abstract: Multicomponent compositions and methods of use thereof are disclosed herein. Some embodiments of the present invention include multicomponent compositions comprising a first component and a second component, where the first component comprises a notch influencing molecule and the second component comprises a GPCR targeted molecule. Kits comprising the multicomponent composition are also disclosed. Methods for providing the multicomponent composition to one or more cells are additionally provided. Further embodiments include methods of using the multicomponent composition such as, for example, methods of administering the multicomponent composition and method of treating organisms (such as mammals) using the multicomponent composition.

Abstract: Disclosed are peptide agents and uses thereof that are analogs of biologically active peptides such as somatostatin and bombesin. The compounds of the invention have the general formula X-Y-Z-Q, where X is a cytotoxic agent, therapeutic agent, detectable label or chelating group, and Q is a biologically active peptide. In peptide agents of the invention Y is optionally a hydrophilic polymer or peptide, and Z is a linking peptide bonded to Q at the amino terminus of Q, having two, three, four, or five, amino acid residues selected to link X to Q, while retaining the biological activity of Q. Methods of using these peptide agents in the diagnosis and treatment of diseases are also disclosed.
