Each protein was also categorized according to its function. The following functional categories were regulated according to the number of proteins involved: cytoskeleton: 14, protein folding: 6, lipid metabolism: 3, cell-matrix interaction: 3, carbohydrate metabolism: 2, redox regulation: 2, respiratory chain: 2, gene expression: 2, others: 5. Thus, proteins related to cytoskeleton, lipid metabolism, cell-matrix contraction, and protein folding were most significantly regulated.
