The paper is entitled Gene therapy targeting survivin selectively induces pulmonary vascular apoptosis and reverses pulmonary arterial hypertension. It's published in the June issue of The Journal of Clinical Investigation. In an accompanying editorial entitled Lessons learned from cancer may help in the treatment of pulmonary hypertension, written by French researcher Serge Adnot, the journal stated: "These findings raise important issues regarding the role of survivin in the pathogenesis of PAH, its value as a prognostic indicator, and its use as a target for new therapeutic strategies."

The latest research builds on previous work by the group, published a few months ago in Circulation Research, showing that an orally available drug, Dichloroacetate, selectively enhances apoptosis in PAH and thus reverses PAH, prolonging the survival of rats. Because this oral therapy has already been tried in humans with congenital mitochondrial diseases, the team is initiating a clinical trial in human PAH. Similarly, newer drugs that inhibit Survivin, currently in trials in oncology, might also be directly applicable to PAH patients, Dr. Michelakis explains.
