Anotace	We quantified CO2–dependent reductive carboxylation glutaminolysis (RCG) and CO2–independent 2HG production in HTB-126 and MDA-MB-231 breast carcinoma cells by measuring 13C incorporation from 1-13C-glutamine into citrate, malate, and 2-hydroxyglutarate (2HG), for which we found a substantial enrichment that ceased upon IDH2 silencing. Relatively high basal 12C-2HG levels existed (5-fold higher vs. non-tumor HTB-125 cells) and 13C-2HG was formed despite the absence of any idh2 and idh1 mutations in HTB-126 cells. Since RCG is enhanced at hypoxia (frequent in solid tumors) and 2HG can be formed without idh1/2 mutations, we suggest 2HG as an analytic marker (in serum, urine, or biopsies) predicting malignancy of breast cancer in all patients
