    A widely distributed metalloenzyme class enables gut microbial metabolism of host- and diet-derived catechols

    Vayu Maini Rekdal et al.
    A previously unrecognized group of metalloenzymes enables human gut microbes to metabolize dietary molecules and neurotransmitters and likely mediates interactions and metabolism among environmental microorganisms.

    Abundant toxin-related genes in the genomes of beneficial symbionts from deep-sea hydrothermal vent mussels

    Lizbeth Sayavedra et al.
    Beneficial symbiotic bacteria encode an exceptional number of toxin-related genes that are all expressed by the symbionts in the host, supporting their key role in host-microbe interactions.

    Dichotomous role of the human mitochondrial Na+/Ca2+/Li+ exchanger NCLX in colorectal cancer growth and metastasis

    Trayambak Pathak et al.
    Colorectal tumors down-regulate the mitochondrial Na+/Ca2+/Li+ exchanger (NCLX) to alter mitochondrial Ca2+ signaling and initiate transcriptional and metabolic reprogramming that drives tumor chemo-resistance and metastasis.

    Remodeling of whole-body lipid metabolism and a diabetic-like phenotype caused by loss of CDK1 and hepatocyte division

    Jin Rong Ow et al.
    Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.

    In vivo proximity labeling identifies cardiomyocyte protein networks during zebrafish heart regeneration

    Mira I Pronobis et al.
    Proximity labeling-based proteomic strategies applied in zebrafish identify new insights into protein network changes in heart muscle cells during regeneration and implicate Rho A as a target of ErbB2 signaling during zebrafish heart regeneration.

    Endothelial heterogeneity across distinct vascular beds during homeostasis and inflammation

    Ankit Jambusaria et al.
    Vascular endothelial cells in the brain, heart and lung exhibit tissue-specific heterogeneity and plasticity, expressing genes that were traditionally thought to be only expressed by the surrounding parenchymal tissue cells.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat et al.
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    Sleep-promoting effects of threonine link amino acid metabolism in Drosophila neuron to GABAergic control of sleep drive

    Yoonhee Ki, Chunghun Lim
    Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.
