PV or ET
subject who has polycythemia vera or essential thrombocythemia
Procedure: Blood specimen
4 green top tube 40 cc of blood draw
- Stem cell function [ Time Frame: at one time study visit ]Assess the effects of RG7112 on MPN HSC/HPC p53 levels and study how it affects MPN stem cell function.
- CD34+ cells assays [ Time Frame: at one time study visit ]Assess the effects of a combination of low doses of IFNα and RG7112 on MPN HSC/HPC. After treatment with RG7112 and IFNα at the various doses, p53, MDM2, MDMX, phosphor-p38, and phosphor-STAT1 levels in MPN CD34+ cells will be measured using monoclonal antibody staining and flow cytometric and immunofluorescence analyses.
