abstract = {How cellular metabolic state impacts cellular programs is a
fundamental, unresolved question. Here we investigated how
glycolytic flux impacts embryonic development, using
presomitic mesoderm (PSM) patterning as the experimental
model. First, we identified fructose 1,6-bisphosphate (FBP)
as an in vivo sentinel metabolite that mirrors glycolytic
flux within PSM cells of post-implantation mouse embryos. We
found that medium-supplementation with FBP, but not with
other glycolytic metabolites, such as fructose 6-phosphate
and 3-phosphoglycerate, impaired mesoderm segmentation. To
genetically manipulate glycolytic flux and FBP levels, we
generated a mouse model enabling the conditional
overexpression of dominant active, cytoplasmic PFKFB3
(cytoPFKFB3). Overexpression of cytoPFKFB3 indeed led to
increased glycolytic flux/FBP levels and caused an
impairment of mesoderm segmentation, paralleled by the
downregulation of Wnt-signaling, reminiscent of the effects
seen upon FBP-supplementation. To probe for mechanisms
underlying glycolytic flux-signaling, we performed
subcellular proteome analysis and revealed that cytoPFKFB3
overexpression altered subcellular localization of certain
proteins, including glycolytic enzymes, in PSM cells.
Specifically, we revealed that FBP supplementation caused
depletion of Pfkl and Aldoa from the nuclear-soluble
fraction. Combined, we propose that FBP functions as a
flux-signaling metabolite connecting glycolysis and PSM
patterning, potentially through modulating subcellular
protein localization.},
