From: 13C tracer analysis suggests extensive recycling of endogenous CO2 in vivo
M + 1-labeled TCA intermediates are observed in non-tumor tissues in vivo. A 13C labeling patterns of metabolites in skeletal muscle and liver from sarcoma-bearing mice receiving [U-13C]-glucose infusion for 3 h. B 13C labeling patterns of metabolites in different types of organs (data from Hui et al., Nature 2017).14. Data are presented as mean ± SD n = 5 animals per group. Data in this figure was after natural abundance correction
