MetabolomicsPKM2 methylation by CARM1 activates aerobic glycolysis to promote tumorigenesis
Metabolic reprogramming is a hallmark of cancer. Herein we discover that the key glycolytic enzyme pyruvate kinase M2 isoform (PKM2), but not the related isoform PKM1, is methylated by co-activator-associated arginine methyltransferase 1 (CARM1). PKM2 methylation reversibly shifts the balance of met...

MetabolomicsGut Commensal Bacteria-Derived Methionine is Required for Host Reproduction by Modulating RNA m6A Methylation of the Insulin Receptor_targeted metabolites

Gut commensal bacteria promote host reproduction by modulating metabolism and nutrition, but the molecular mechanisms by which microbes regulate reproduction remain unclear. Here, we show that gut commensal bacteria promote host reproduction by providing amino-acid methionine, which controls the ...

MetabolomicsSystemic Inflammation Induces Cholestasis via Upregulating a Short Variant of FTO to Remove the m6A Methylation in the 3’-UTR of Cyp7b1 mRNAs in liver
The cholestasis frequently occurs in patients with inflammatory processes. However, the mechanisms of inflammation in inducing cholestasis are still unclear. Here, by using lipopolysaccharide (LPS)-induced cholestasis mouse models, we found that most genes encoding enzymes responsible for bile acid ...

GenomicsDnmt2-dependent methylomes lack biologically relevant DNA methylation patterns [Schistosoma mansoni]
Dnmt2 is a widely conserved protein, which is closely related to eukaryotic DNA methyltransferases. However, Dnmt2 shows a robust tRNA methyltransferase activity and only limited activity towards DNA. Interestingly, a recent study has provided evidence for a biologically important function of Dnmt2-...

TranscriptomicsDNA methylation distinguishes pathologically normal human tissues
Epigenetic control of gene transcription is critical for normal human development and cellular differentiation. While alterations of epigenetic marks such as DNA methylation have been linked to cancers and many other human diseases, interindividual epigenetic variation in normal tissues due to aging...

TranscriptomicsLung adenocarcinoma and mesothelioma DNA methylation
Pathologic differentiation of tissue of origin in tumors found in the lung can be challenging, with differentiation of mesothelioma and lung adenocarcinoma emblematic of this problem. Indeed, proper classification is essential for determination of treatment regimen for these diseases, making accurat...

TranscriptomicsDNA methylation and expression profiling study for prostate cancer
Microarray-based DNA methylation and gene expression profiling was carried out using a panel of prostate cancer cell lines (LNCaP-FGC, DU-145, and PC-3) and the control normal prostate RWPE1 cell line. The identification of prostate cancer-specific methylation markers was based on the following crit...

TranscriptomicsGenome-wide connection between DNA methylation and DNA replication timing
DNA methylation and DNA replication timing were examined across a variety of human tissues and cell lines, applying microarray-based techniques. The analyses revealed that late-replicating DNA was demethylated compared to the methylation of early-replicating regions. DNA methylation: Epstein-Barr-Vi...

TranscriptomicsAnalysis of fetal livers from male mice after protein-restricted diet in mothers
Prenatal nutrition as influenced by nutritional status of the mother has been identified as a determinant of adult disease. Feeding low-protein diets during pregnancy in rodents is a well-established model to induce “programming” events in offspring. We hypothesized that protein restriction would in...
