IDH1 and neoplasm: Moreover, several studies reported that mutant IDH1 in gliomas regulated a number of physiological processes such as inflammatory pathways, metabolic metabolism, hypoxia sensing, histone demethylation, and changes in DNA methylation causing DNA strand breaks, apoptosis, autophagy, and tumor cell death (Gilbert et al., 2014; Viswanath et al., 2018; Zhang et al., 2019; Kadiyala et al., 2021; Pirozzi and Yan, 2021).
