To see whether cancer stem cell renewal involves a chain of events similar to that used by embryonic stem cells, and whether the process was affected by oxygen levels, Semenza and graduate student Chuanzhao Zhang focused their studies on two human breast cancer cell lines that responded to low oxygen by ramping up production of the protein ALKBH5, which removes methyl groups from mRNAs.

But last April he also voted for the HOPEAct, a Bush - supported «compromise» bill that would open up federal funding for research that does not involve the creation, destruction, or injury of embryos; seeing as there are not yet any embryonic stem cells lines that meet this condition (ACT hasn't yet proven that their technique poses no «risk of injury»), the HOPE funding would only be available for non-embryonic stemcells.

Acute myeloid leukemia (AML) is the leading cause of leukemia mortality in the United States.1 Curative treatment involves intensive induction chemotherapy, before proceeding to either consolidation chemotherapy or allogeneic stem cell transplantation based on the patient's risk for relapse.2 This approach has been employed for > 4 decades and, although most individuals achieve complete remissions with front - line therapy, 3 the majority of patients ultimately relapse with drug - resistant disease, and overall survival rates remain disappointingly poor.4 The limited ability of many patients to tolerate the intense chemotherapy - based treatments, in particular hematological toxicity, further contributes to the poor outcomes noted in this disease.
