Figure Lengend Snippet: Effect of supplementation with 10-formyl-THF or formate on cisplatin-resistant cell survival and apoptotic cell death in cells with DLAT knockdown. Cells cultured under sublethal doses of cisplatin were treated with 10-formyl-THF ( a ) or formate ( b ) at indicated concentrations for 48 h. Apoptosis (top) and cell viability (bottom) were determined. 10-formyl-THF rescues cisplatin-resistant cell growth ( c ) and MT-CO2 expression ( d ) in cells lacking K44 MTHFD2 acetylation. Cisplatin-treated cells expressing K44R MTHFD2 were subjected to 10 μM 10-formyl-THF for 24 h followed by annexin V staining, cell viability assay, and assessment of MT-CO1, MT-CO2, and COXIV levels by immunoblotting and quantitative RT-PCR. Cells expressing the acetyl-mimetic mutant form of MTHFD2 K44Q were included for comparison. Effect of MT-CO2 overexpression on cisplatin-resistant cell growth in cells lacking K44 MTHFD2 acetylation ( e ) or DLAT ( f ) by K44R MTHFD2 expression or DLAT knockdown, respectively. Data are mean ± SD from 4 independent biological replicates for ( d ) and 3 for ( a – c , e , f ). P values were determined by one-way ANOVA. Source data are provided as a Source Data file.

Figure Lengend Snippet: Mitochondrial network show signs of disorganization in striatal (upper panels) and cortical (lower panels) regions of NAGLU −/− mice Forty μm-thick coronal brain sections of 8-month-old wild type (WT) and NAGLU −/− mice were stained with the mitochondrial marker mitochondrially encoded cytochrome c oxidase I (MT-CO1, cytochrome c oxidase subunit 1 COX1). Nuclei were stained with Hoechst.
