Epsilon-V1-2 (ε-V1-2), a PKCε-derived peptide, is a selective PKCε inhibitor. Epsilon-V1-2 inhibits the translocationof PKCε, but not α-, β-, and δPKC[1].

体外研究 (In Vitro)
Epsilon-V1-2 (ε-V1-2), a PKCε-derived peptide containing the site for its specific receptor for activated C kinase (RACK), inhibits translocation of PKCε and reduces insulin response to glucose[1]. Epsilon-V1-2 (ε-V1-2; 1 µM, 24 hours) treatment significantly inhibits Oleic acid (OA)-induced connexin 43 (Cx43) Ser368 phosphorylation and prevents OA-induced gap junction disassembly in cardiomyocytes[2].

体内研究 (In Vivo)
Epsilon-V1-2 (20 mg/kg/day; osmotic pumps; daily; for 4 weeks) treatment significantly improves the beating score in a murine heterotopic transplantation model. Epsilon-V1-2 reduces infiltration of macrophages and T cells into the cardiac grafts, and decreases parenchymal fibrosis. Epsilon-V1-2 treatment almost abolishes the rise in pro-fibrotic cytokine, TGF-β and monocyte recruiting chemokine MCP-1 levels[3].
