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. Therefore, the radiological and genetic features of 193 patients affected by astrocytic neoplasms, with specific associations with IDH gene status were analyzed to address the aforemen-tioned issues.

Geisbrecht and Gould (1999) found that purified recombinant human PICD catalyzed oxidative decarboxylation of isocitric acid and required NADP+ for the reaction. Mutation of the IDH1 gene was strongly correlated with a normal cytogenetic status; it was present in 13 of 80 cytogenetically normal samples (16%). (2014) showed that mutant IDH1 and IDH2 (147650) block liver progenitor cells from undergoing hepatocyte differentiation through the production of 2-hydroxyglutarate (2HG) and suppression of HNF4A (600281), a master regulator of hepatocyte identity and quiescence. These mutants showed increased numbers of early hematopoietic progenitors and developed splenomegaly and anemia with extramedullary hematopoiesis, suggesting a dysfunctional bone marrow niche.
