Research Synopsis

One prime focus of ongoing investigations is on key regulators of erythropoiesis, especially within clinically relevant anemia contexts. EPO/EPOR effects and molecular action mechanisms are a major highlight. Using combined approaches of knocked-in EPOR alleles, primary progenitor cell systems, transcriptome and phosphoproteomic analyses, we have discovered intriguing new major EPOR targets including cyclin G2 (a cell cycle brake); Podocalyxin (a cell surface adhesion/migration factor); Spi2A (an atypical intracellular serpin); TRIB2 & TRIB3 molecular adaptors; and “RHEX” as a novel component of the human EPOR. For each, we have developed novel knockout mouse models and/or primary human progenitor cell GOF / LOF systems with exciting phenotypes exhibited (as recent examples, see Verma, et al, 2014. J Exp Med 211: 1715-1722 Abstract in PubMed and Dev et al, 2013. J Exp Med. 210: 225-232 Abstract in PubMed). In addition, aggressive phosphoproteomic analyses are revealing important new EPO targets and transducers specific to human EPOR/JAK2 complexes. The importance of such work is underlined further by EPO's ability to cytoprotect ischemically injured cardiac, neural and renal tissues; and to modulate tumorigenesis. In addition, novel EPO mimetics are emerging with distinct EPOR activation properties that merit mechanistic attention as they enter the clinic.
