20160060312 | Development of Protein-Based Biotherapeutics That Penetrates Cell-Membrane and Induces Anti-Pancreatic Cancer Effect - Improved Cell-Permeable Suppressor of Cytokine Signaling (iCP-SOCS3) Proteins, Polynucleotides Encoding the Same, and Anti-Pancreatic Cancer Compositions Comprising the Same - In principle, protein-based biotherapeutics offers a way to control biochemical processes in living cells under non-steady state conditions and with fewer off-target effects than conventional small molecule therapeutics. However, systemic protein delivery in vivo has been proven difficult due to poor tissue penetration and rapid clearance. Protein transduction exploits the ability of some cell-penetrating peptide (CPP) sequences to enhance the uptake of proteins and other macromolecules by mammalian cells. Previously developed hydrophobic CPPs, named membrane translocating sequence (MTS), membrane translocating motif (MTM) and macromolecule transduction domain (MTD), are able to deliver biologically active proteins into a variety of cells and tissues. Various cargo proteins fused to these CPPs have been used to test the functional and/or therapeutic efficacy of protein transduction. The recombinant proteins consisting of suppressor of cytokine signaling 3 (CP-SOCS3) protein fused to the fibroblast growth factor (FGF) 4-derived MTM were developed to inhibit inflammation and apoptosis. However, CP-SOCS3 fusion proteins expressed in bacteria cells were hard to be purified in soluble form. To address these critical limitations, CPP sequences called advanced MTDs (aMTDs) have been developed in this art. This is accomplished by (i) analyzing previous developed hydrophobic CPP sequences to identify specific critical factors (CFs) that affect intracellular delivery potential and (ii) constructing artificial aMTD sequences that satisfy each critical factor. In addition, solubilization domains (SDs) have been incorporated into the aMTD-fused SOCS3 recombinant proteins to enhance solubility with corresponding increases in protein yield and cell-/tissue-permeability. These recombinant SOCS3 proteins fused to aMTD/SD having much higher solubility/yield and cell-/tissue-permeability have been named as improved cell-permeable SOCS3 (iCP-SOCS3) proteins. Previously developed CP-SOCS3 proteins fused to MTM were only tested or used as anti-inflammatory agents to treat acute liver injury. In the present art, iCP-SOCS3 proteins have been tested for use as anti-cancer agents in the treatment of pancreatic cancer. Since SOCS3 is frequently deleted in cancer cells and loss of SOCS3 promotes resistance to apoptosis and proliferation, we reasoned that iCP-SOCS3 could be used as a protein-based intracellular replacement therapy for the treatment of pancreatic cancer. The results demonstrated in this art support this reasoning: treatment of pancreatic cancer cells with iCP-SOCS3 results in reduced cancer cell viability, enhanced apoptosis and loss of cell migration/invasion potentials. Furthermore, iCP-SOCS3 inhibits the growth of pancreatic cancer in a subcutaneous xenografts model. In the present invention with iCP-SOCS3, where SOCS3 is fused to an empirically determined combination of newly developed aMTD and customized SD, macromolecule intracellular transduction technology (MITT) enabled by the advanced MTDs may provide novel protein therapy against pancreatic cancer. | 03-03-2016 |
20160068825 | Development of Protein-Based Biotherapeutics That Penetrate Cell-Membrane and Induce Anti-Cancer Effect- Cell-Permeable Glutathione Peroxidase7 (CP-GPX7) in Gastrointestinal Track (GIT), Polynucleotides Encoding the Same, and Anti-Cancer Compositions Comprising the Same - Gastrointestinal track (GIT) including oesophageal and gastric cancers are a leading cause of cancer death worldwide. Limited therapeutic options highlight the need to understand the molecular changes responsible for the disease and to develop therapies based on this understanding. Advances in understanding the molecular changes responsible for GIT cancer etiology and progression are expected to improve disease diagnosis and treatment. The glutathione peroxidase 7 (GPX7) a candidate tumor suppressor implicated in GIT cancers including esophageal and gastric cancers has been implicated as a potential tumor suppressor gene in esophageal and gastric cancers; however, this claim is controversial. The goal of this invention is to develop cell-permeable (CP-) form of GPX7 to utilize the therapeutic potential of GPX7 in the treatment of GIT cancers. Using macromolecule intracellular transduction technology (MITT) enabled by novel hydrophobic cell-penetrating peptide (CPP) called advanced macromolecule transduction domains (aMTDs) which are able to promote protein uptake by mammalian cells and tissues, the first CP-GPX7 protein has been developed to deliver biologically active GPX7 protein into human oesophageal and gastric cancer cells, resulting in suppression of cell phenotypes and induction of changes in biomarker expression consistent with previously described effects of GPX7. CP-GPX7 recombinant protein fused to aMTD also suppresses the growth of human gastric tumors in a mouse xenograft model. The results of this art provide further evidence that GPX7 can function as an anti-cancer molecule and suggest that practical methods to augment GPX7 function could be useful in treating of some types of GIT cancers. The present art with CP-GPX7 recombinant protein illustrates the use of protein-based therapies to target GIT cancers. | 03-10-2016 |
