Gene expression analysis of healthy adults rapidly transported to high altitude
Objective To identify novel genes that change expression in healthy adults exposed to hypobaric hypoxia. Background The uniform and rapid transfer of adults from McMurdo Station (sea level, SL) in Antarctica to the South Pole (2835m, SP) provides a unique opportunity to study the changes in gene exp...
