Figure 5. Protein processing pathways in endoplasmic reticulum. The figure [Modified with permission from Kyoto Encyclopedy of Genomes and Genes (KEGG) website [33,34]— shows various genes that are involved in the protein processing. For FECD samples, genes in Red boxes were up-regulated, p<0.05, Green box were down-regulated, p<0.05, Orange box: upregulated with p>0.05, Grey box: present in UPR array but not regulated, White box: not present in UPR array.
