Hannele Ruohola-Baker and a team of researchers at the University of Washington recently discovered that two proteins responsible for regulating how cells break down glucose are also essential for stem cell development. The scientists showed that the proteins HIF1 alpha and HIF2 alpha are both required to reprogram adult human cells into pluripotent stem cells, which have the ability to mature into any cell type in the body. Taking a closer look at what each protein does on its own, the researchers found that HIF1 alpha was beneficial for reprogramming throughout the process, whereas HIF2 alpha was required at early stages but was detrimental at later stages of reprogramming. Because the two proteins also play a role in transforming normal cells into cancer cells, the findings could lead to future advances in cancer research.
