Figure 3. Venn diagram of the differentially expressed proteins in the three individual comparisons. Differentially expressed proteins in HeLa vs. HCK1T; SiHa vs. HCK1T; and C-33A vs. HCK1T, are represented with the blue, red and green circles, respectively. Five proteins are unique in the comparison of the HPV-negative cell line (C-33A) to the normal cervical keratinocytes (HCK1T), and 13 proteins are common between the comparisons of the HPV-positive cell lines (HeLa and SiHa) to HCK1T, while not present in the comparison between C-33A vs. HCK1T.
