title: The effect of the JAK2 V617F mutation on PRV-1 expression.
abstract: JAK2(V617F)an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2(V617F) on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2(V617F) increased both PRV-1 protein and mRNA levels in murine myeloid cells. A JAK2 inhibitor eliminated the V617F-induced increase in PRV-1 expression.
