2 Figure 1 LKB1 Loss Promotes Tumorigenesis through Interlinked Metabolic and Epigenetic Reprogramming In comparison to KRASG12D/+ (K) cells, KRASG12D/+;LKB1−/− (KL) cells were highly glycolytic, with glucose diverted for serine biosynthesis that supports synthesis of S-adenosyl methionine (SAM) and eventually leads to increased DNA methylation, particularly the methylation at retrotransposon elements. Loss of LKB1 leads to elevated DNA methyltransferase (DNMT) activity. Cell Metabolism  , DOI: ( /j.cmet ) Copyright © 2016 Elsevier Inc. Terms and Conditions
