Updated project metadata. A hyperlipidaemia model of L02 cells was established using free fatty acids (FFA, oleate and palmitate, 2:1; Sigma-Aldrich, USA) at a final concentration of 1 mM for 24 h. Cells were allowed to attach overnight prior to HTG-medicated serum for 24 h and then exposed to FFA during drug treatment. After treatment, LO2 cells were harvest and stored at -80 ℃, lactylation proteomics was performed by Jingjie PTM BioLabs (Hangzhou, China).
