Article Title: The lysine degradation pathway analyzed with 1 H-NMR-targeted metabolomics of MG63 cells on poly( l -lactide)-based scaffolds

doi: 10.1039/d5ra05954b

Figure Lengend Snippet: Representative 1 H NMR spectra of MG63 cell metabolites after being cultured on different types of PLLA. The cells were seeded on PLLA, PLLA-Cel, PLLA-Col, and PLLA-Cel-Col for 7 days. Peak assignments: 1 – lactic acid, 2 – 3-hydroxy- l -proline, 3 – glucosylgalactosylhydroxylysine, 4 – lysine, 5 – glucosylproline, 6 – pyruvic acid, 7 – succinic acid, 8 – α-ketoglutaric acid, 9 – proline, 10 – 5-hydroxylysine, 11 – oxaloacetic acid, 12 – acetyl-CoA, 13 – FADH 2 , 14 – 2-phosphoglyceric acid, 15 – cAMP, 16 – 3-phosphoglyceric acid, 17 – phosphoenolpyruvic acid, 18 – NADH. Unassigned peaks represent unknown compounds not in the HMDB database, residual solvent signals, or overlapping signals. The water signal region (4.6–5.0 ppm) was excluded from analysis to minimize interference.

Figure Lengend Snippet: Selected metabolites in the lysine degradation pathway. (A) The initial steps of the lysine degradation pathway and (B) the metabolite concentrations from MG63 cells cultured on PLLA, PLLA-Cel, PLLA-Col, and PLLA-Cel-Col for 7 days. The bar graph illustrating the mean ± SD ( n = 3) of each metabolite concentration (μM) is derived from 1 H NMR metabolomic data. The paired bars indicate a comparison of means; (★) and (★★), and (★★★) indicate significant differences when p < 0.05, 0.01, and 0.001, respectively.
