C4A and cancer: In addition, while many proteins associated with the cancer, organismal injury and abnormalities and cellular movement network were similarly expressed in both cell types (i.e., IGFBP, CCL5 and TNFRSF21), several proteins (i.e., IGFBP3, ITGA1, and C4A/C4B) were dissimilarly impacted in the two cell types.
