Growth factors induce ZFP36, which binds and decays metabolic enzyme/transporter mRNAs—especially Eno2—tuning glycolytic metabolism.

Outcome
ZFP36-mediated decay of metabolic mRNAs including Eno2

Key findings

ZFP36 family members are acute growth-factor immediate-early genes; they bind many metabolic mRNAs and promote Eno2 mRNA decay; loss elevates ENO2/PEP and alters the metabolome; regulation appears in neonatal retinal angiogenesis.

Methodology

Mapped ZFP36 induction and eCLIP targets after growth-factor stimulation in MEFs, validated Eno2 decay, metabolomics, and retinal angiogenesis after endothelial Zfp36 loss.

Limitations

Does not prove Eno2 is the sole metabolic effector of ZFP36 in every tissue or that ZFP36 drugs would safely remodel metabolism clinically.

How this study connects

Role on claims

Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.

  • SupportsMetabolismconcept

    Multiple empirical papers in this library examine metabolism with mechanistic biological findings.

    Evidence for the claim as stated.

  • SupportsMetabolismconcept

    ZFP36 family members are acute growth-factor immediate-early genes; they bind many metabolic mRNAs and promote Eno2 mRNA decay; loss elevates ENO2/PEP and alters the metabolome; regulation appears in neonatal retinal angiogenesis.

    Evidence for the claim as stated.

  • SupportsMetabolismconcept

    Systems and scales differ across metabolism studies (species, tissues, methods), so mechanisms should not be over-generalised.

    Evidence for the claim as stated.

  • Two papers are weak luciferase examples. Foxp3 stability was scored by bisulphite sequencing and ChIP: a TSDR-like element is demethylated in stable Tregs, and weak demethylation predicts unstable TGF-β–induced Foxp3 (mostly mouse). ZFP36 family members are growth-factor immediate-early genes that bind metabolic mRNAs, promote Eno2 decay, raise ENO2/PEP when lost, and affect neonatal retinal angiogenesis — eCLIP and metabolomics, not a promoter-luciferase paper.

    Evidence for the claim as stated.

  • MC4R shows that a cAMP/reporter signal can look normal while trafficking is impaired, so luciferase-like pathway readouts disagree with surface-expression assays. Foxp3 and ZFP36 papers barely use luciferase at all: DNA methylation/ChIP versus mRNA decay and metabolomics.

    Evidence for the claim as stated.
