Quantitative proteomics reveals changes in amino acid and glutathione metabolism in congenital cataracts. (A–C) Grid visualization of downregulated DEPs identified in K6W-Ub lenses at (A) E15, (B) P1, and (C) P30 and. (D–F) Grid visualization of upregulated DEPs identified in K6W-Ub lenses at (D) E15, (E) P1, and (F) P30. Shown in columns are the top 10 associated KEGG pathways, which are ordered by p-values. KEGG pathways involved in glutathione and amino acid metabolism (highlighted in red). Rows indicate DEPs, based on comparisons of K6W-Ub relative to WT. In A-C, blue shades indicate the degree of downregulation in K6W-Ub lenses, with darker shades corresponding to more downregulation, according to the key next to each grid. In D-F, red shades indicate the degree of upregulation in K6W-Ub lenses, with darker shades corresponding to more upregulation, according to the key next to each grid.
