Cellular energy status influences cancer via adenosine monophosphate (AMP)-activated protein kinase (AMPK) signaling. Targeting YTHDF1 modifications with AMPK agonists or ketogenic diets inhibits tumor growth, offering new cancer treatment strategies.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Research
Background:
- Aberrant cellular energy metabolism is linked to tumorigenesis, but mechanisms are unclear.
- Adenosine monophosphate (AMP)-activated protein kinase (AMPK) senses energy stress and regulates cancer.
- YTHDF1 protein modifications are implicated in cancer progression.
Purpose of the Study:
- To investigate the role of AMPK in regulating YTHDF1 post-translational modifications.
- To elucidate how these modifications affect YTHDF1 function and protein translation.
- To explore the therapeutic potential of targeting this pathway in cancer.
Main Methods:
- Investigated energy deprivation-induced AMPK activation.
- Analyzed phosphorylation and O-GlcNAcylation of YTHDF1.
- Assessed YTHDF1 phase separation and interaction with eIF3b.
- Evaluated tumor cell growth inhibition in vitro and in vivo using AMPK agonists and ketogenic diet.
Main Results:
- AMPK activation phosphorylates YTHDF1 at Ser198, counteracting its O-GlcNAcylation.
- YTHDF1 phosphorylation suppresses phase separation and eIF3b interaction, reducing protein translation.
- AMPK agonists and ketogenic diet inhibit tumor cell growth by enhancing YTHDF1 phosphorylation.
Conclusions:
- A novel mechanism links cellular energy status to YTHDF1 modifications and protein translation.
- Targeting YTHDF1 post-translational modifications via metabolic interventions shows therapeutic promise for cancer.
