Posttranslational modification dramatically enhances protein complexity, but the function and precise mechanism of novel lysine acylation modifications remain unknown. Chemoresistance remains a daunting challenge to successful treatment. We found that lysine butyrylation (Kbu) is specifically upregulated in chemoresistant tumor cells and tissues.

Metastatic cancer cells upregulate ANO1 to activate cell-intrinsic and -extrinsic mechanisms that alter cholesterol metabolism and stimulate fibroblasts, which can be targeted with ANO1 inhibitors to inhibit metastatic growth. See related commentary by Singh and Mehla, p. 1759.

Posttranslational modifications add tremendous complexity to proteomes; however, gaps remain in knowledge regarding the function and regulatory mechanism of newly discovered lysine acylation modifications. Here, we compared a panel of non-histone lysine acylation patterns in metastasis models and clinical samples, and focused on 2-hydroxyisobutyrylation (Khib) due to its significant upregulation in cancer metastases. By the integration of systemic Khib proteome profiling in 20 paired primary esophageal tumor and metastatic tumor tissues with CRISPR/Cas9 functional screening, we identified N-acetyltransferase 10 (NAT10) as a substrate for Khib modification.

Chemotherapy remains an important approach for the treatment of liver metastases from uveal melanoma (UM). Compared with systemic chemotherapy, regional chemotherapy has similar efficacy and fewer systemic adverse effects. Regional chemotherapy for UM liver metastases includes hepatic artery infusion (HAI), transarterial chemoembolization (TACE), and isolated hepatic perfusion (IHP).
