4、ition of 50 mM and 100 mM of D-alpha-Hydroxyglutaric acid (D-2-HG) results in partial and nearlycomplete inhibition of CeKDM7A, respectively. To further examine the mode of interaction between -KG andD-2-HG, CeKDM7A are incubated with a fixed concentration (50 mM) of D-2-HG and increasing amount of

5、-KG. A partial inhibition of KDM7A toward both H3K9me2 and H3K27me2 peptides is observed in thepresence of 50 mM D-2-HG and 100 M -KG. Addition of 300 M -KG is capable of reversing the inhibitionof CeKDM7A by 50 mM D-2-HG, indicating that D-2-HG is a weak competitive inhibitor against -KG towardthe

6、CeKDM7A demethylase. D-2-HG with Ki of 10.871.85 mM for inhibiting KDM5B/JARID1B/PLU-1 1. D-alpha-Hydroxyglutaric acid (R-2HG) increases the lifespan of C. elegans. (R)-2HG interacts distinctly with the-KG dependent dioxygenases. The intracellular (R)-2HG levels are 20-100 fold higher in U87 and HCT

7、 116cells expressing IDH1(R132H) than in control cells. The elevated (R)-2HG levels are comparable to thosefound in cells treated with octyl (R)-2HG, and levels reported for IDH1-mutant tumor samples 2.PROTOCOLKinase Assay 1 To assay human JHDM1A/KDM2A demethylase activity toward H3K36me2, His tagge

8、d JHDM1A is firstobtained by transforming pET28a-JHDM1A into Escherichia coli BL21 and protein expression is induced byaddition of 1 mM IPTG at 30C when cell density reaches 0.5 OD600 units. Cells are lysed by sonication andNi-NTA agarose is used to purify His-JHDM1A fusion proteins. Histone demethy

9、lase assay is carried out byincubating 2 g oligonucleosomes, 4 g purified His-JHDM1A, and/or 10-50 mM D-2-HG in histonedemethylation buffer 50 mM HEPES (pH 8.0), 625 M Fe(NH4)2(SO4)2, 0.1-0.5 mM -KG, 2 mM ascorbateat 37C for 2-3 hr and the reactions are stopped by the addition of SDS loading buffer

10、and subsequentlyanalyzed by western blotting using anti-H3K36me2 antibody. To measure CeKDM7A demethylase activitytoward H3K9me2 and H3K27me2, two synthetic dimethylated peptides H3K9me2 ARTKQTARK(me2)STGGKA and H3K27me2 QLATKAARK (me2)SAPAS are used as substrates. Demethylase assaysare carried out

11、in the presence of 10 g enzyme, 1 g peptide in 20 l buffer 20 mM Tris-HCl (pH 7.5), 150mM NaCl, 50 M (NH4)2Fe(SO4)2, 100 M -KG, 2 mM Vc, 10 mM PMSF for 3 hr. The demethylationreaction mixture is desalted by passing through a C18 ZipTip. To examine the inhibitory effect of 2-HG,various concentrations

Thesamples are analyzed by a MALDI-TOF/TOF mass spectrometer 1.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Cell Assay 2 U87 cells, HCT 116 IDH1(R132H/+) cells, and HEK

13、293 cells are seeded in 12-well plates and after overnightincubation are treated with indicated concentrations of each compound (e.g., 400 and 800 M D-2-HG). Afterharvesting, cells are stained with Acridine Orange (AO) and DAPI. Cell number and viability are measuredbased on AO and DAPI fluorescence
