Abstract: A majority of neuroendocrine (NE) cancers overexpress somatostatin receptors (SSTRs). Disclosed herein are anti-SSTR2 monoclonal antibodies, and antibody-drug conjugates (ADCs) for use as NE cancer targeting therapeutics. Also disclosed is an isolated nucleic acid encoding the disclosed antibodies, as well as nucleic acid vectors containing this isolated nucleic acid operably linked to an expression control sequence. Also disclosed are cells transfected with these vectors and the use of these cells to produce the disclosed recombinant antibodies. Also disclosed is a method of treating a neuroendocrine (NE) cancer in a subject, comprising administering to the subject an effective amount of the disclosed antibody conjugated to an anti-cancer agent.

Abstract: Disclosed herein is an optogenetics-based gene therapy that involves channelrhodopsin fusion proteins having an inner mitochondrial membrane-mitochondrial localization signal (IMM-MLS) that can effectively target the fusion protein to an inner mitochondria membrane, and a channelrhodopsin ion channel domain that can change the mitochondrial membrane potential (??m) when light is present. The disclosed optogenetics-based gene therapy system can in some embodiments further involve luciferase fusion proteins to stimulate the channelrhodopsin without reliance on external light that has an outer mitochondrial membrane-mitochondrial localization signal (OMM-MLS) that can effectively target the luciferase fusion protein to an outer mitochondrial membrane, and a luciferase protein that can produce a bioluminescence in the presence of a luciferase substrate.
