TY - JOUR T1 - BRain tumor clue AU - Stephenson J Y1 - 2009/05/20 N1 - 10.1001/jama.2009.690 JO - JAMA SP - 1977 EP - 1977 VL - 301 IS - 19 N2 - The researchers found that IDH1 mutations in glioma tumor cells resulted in reduced levels of α-ketoglutarate (α-KG), which regulates the level of a substance that facilitates angiogenesis and tumor growth when oxygen is low. Adding a modified form of α-KG to glioma cells grown in culture reverses this effect. SN - 0098-7484 M3 - doi: 10.1001/jama.2009.690 UR - http://dx.doi.org/10.1001/jama.2009.690 ER -
