The enzymatic activity of the proteins that were produced from normal and mutant IDH1 and IDH2 genes was determined in cultured glioma cells that were transfected with these genes. [PubMed: 25043048] (2014) concluded that their studies provided a functional link between IDH mutations, hepatic cell fate, and IHCC pathogenesis, and presented a novel genetically engineered mouse model of IDH-driven malignancy. Correspondingly, genetically engineered mouse models expressing mutant Idh in adult liver showed an aberrant response to hepatic injury, characterized by Hnf4a silencing, impaired hepatocyte differentiation, and markedly elevated levels of cell proliferation. Lu et al. (2004) proposed that the hydrogen bond formed between asp279 and ser94 may mimic an inactivating serine phosphorylation. The authors also identified other genes that contained mutations they considered probable initiators. In the process, two hydrogens are also removed. Am. (2008) found that a majority of tumors analyzed had alterations in genes encoding components of each of the TP53 (191170), RB1 (614041), and PI3K (see 171834) pathways.
