Monitoring Jak3 Mrna Levels In Patients With Gvhd After Allogeneic Hematopoietic Stem Cell Transplantation By Real-Time Quantitative Pcr.

Background: Graft-versus-host disease (GVHD) represents a major hurdle impeding the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT). JAK3 plays pivotal roles in the initiation of cytokine-triggered signaling transduction. Recent studies about the murine GVHD model show that targeting JAK3 in donor lymphocytes with a chemical inhibitor such as WHI-P131 may be useful in the prevention of severe GVHD. However, the level of JAK3 expression in patients with GVHD has not been reported. The current study is to develop a reliable and rapid real-time quantitative PCR (Q-PCR) method using Taqman Probe for detecting JAK3 in allo-HSCT recipients.
