A tissue cell growth-promoting solution produced by this invention comprising water containing at least 1 to 500 ppm of active oxygen, when applied to a wound, supplies active oxygen originating from outside the biobody to supplement the active oxygen produced by the biobody's own protective system cells such as neutrophils and macrophages which gather at the wound site, thus increasing the concentration of active oxygen at the site of the wound, mimicking a state in which a large quantity of such bio-signals is secreted by the biobody itself, to promote the reconstruction of tissues, the action corresponding to the last of the four main steps involved in wound healing biochemical processes of "blood vessel reaction", "blood vessel coagulation", "inflammation", "reconstruction of tissues" and which would otherwise have to rely on the natural healing power of the biobody itself.

The methods described herein enable the evaluation of compounds on subjects to assess their therapeutic efficacy or toxic effects. The target of analysis is the underlying biochemical process or processes (i.e., metabolic process) thought to be involved in disease pathogenesis. Molecular flux rates within the one or more biochemical processes serve as biomarkers and are quantitated and compared with the molecular flux rates (i.e., biomarker) from control subjects (i.e., subjects not exposed to the compounds). Any change in the biomarker in the subject relative to the biomarker in the control subject provides the necessary information to evaluate therapeutic efficacy of an administered drug or a toxic effect and to develop the compound further if desired. In one aspect of the invention, stable isotope-labeled substrate molecules are administered to a subject and the label is incorporated into targeted molecules in a manner that reveals molecular flux rates through one or more metabolic pathways of interest. By this method, a comparison between subjects and control subjects reveals the effects of the chemical entity or entities on the biomarkers. This, in turn, allows for the identification of potential therapeutic uses or toxicities of the compound. Combinations of compounds can also be systematically evaluated for complementary, synergistic, or antagonistic actions on the metabolic pathways of interest, using the methods of the present invention as a strategy for identifying and confirming novel therapeutic or toxic combinations of compounds.

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. Previously, recombinant proteins consisting of suppressor of cytokine signaling 3 (SOSC3) fused to the fibroblast growth factor (FGF) 4-derived MTM were developed to inhibit inflammation and apoptosis. However, this 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. The development of this art has been 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. Furthermore, 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 SOCS3 recombinant 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-angiogenic agents. Since SOCS3 is known to be an endogenous inhibitor of pathological angiogenesis, we reasoned that iCP-SOCS3 could be used as a protein-based intracellular replacement therapy for inhibiting angiogenesis in tumor cells. The results demonstrated in this art support this following reasoning: Cancer treatment with iCP-SOCS3 results in reduced endothelial cell viability, loss of cell migration potential and suppressed vascular sprouting potentials. 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 cancer cell-mediated angiogenesis.
