  • Title: CARP: fishing for novel mechanisms of neovascularization.
    Author: Samaras SE, Shi Y, Davidson JM.
    Journal: J Investig Dermatol Symp Proc; 2006 Sep; 11(1):124-31. PubMed ID: 17069020.
    Abstract:
    Gene expression profiling of mouse skin wounds has led to the discovery of numerous target genes that may have therapeutic or diagnostic value. Among these, cardiac ankyrin repeat protein (CARP, ankrd1) expression was markedly and persistently elevated in several cutaneous compartments. This review summarizes the current state of knowledge of CARP and its regulation in biological systems. In addition to its role as a nuclear transcription cofactor in many cell types including vascular endothelium, CARP is also a structural component of the sarcomere. CARP transcripts are prominent in cardiogenesis and muscle injury, and they are under complex regulation by cytokines, hypoxia, doxorubicin, and other forms of stress. CARP overexpression in wounds by adenoviral gene transfer leads to a high vascular density, and CARP exerts effects on endothelial behavior. The unusual cellular distribution and actions of CARP make it a novel candidate gene in tissue repair.
