Super excited to share our new publication identifying the food preservative, sorbic acid, as a new PTM. Even cooler is that the deacylation and acylation of this PTM is catalyzed by the non-canonical activity of Class I HDACs using free sorbate (not sorbyl-CoA) www.science.org/doi/10.1126/...
Sorbate induces lysine sorbylation through noncanonical activities of class I HDACs to regulate the expression of inflammation genes
Sorbic acid regulates inflammatory gene expression through the mechanism of lysine sorbylation.

Excited to share this one! We developed an in vivo model for specific manipulation of transfer RNA acetylation and found it serves as a sentinel modification whose loss causes ribosome stalling and stress signaling. Implications for a genetic disorder and cancer.

Happy New Year. I’m pleased to report publication of the Ducker lab’s latest cancer metabolism paper led by graduate student Kyle Dunlap in @cp-cellreports.bsky.social

SLC7A5 is required for cancer cell growth under arginine-limited conditions
Metabolic adaptations are key to cancer cell survival in nutrient-limited microenvironments, but strategies for coping with arginine scarcity are poorly understood. Dunlap et al. use CRISPR screening and metabolomics to identify the plasma membrane transporter SLC7A5 as a citrulline transporter essential for cancer cell growth under arginine limitation.
