Fig. 3

Specifically expressed proteins. This figure displays a Venn diagram of the specific proteins for the cell lines MKL-1, MKL-2, PeTa, WaGa, and MCC13. First, each cell line was compared to the reference cell line HaCaT and the proteins specific to each MCC cell line were determined. Due to the small difference between HaCaT and BroLi, BroLi has been omitted. Few proteins were found in several cell lines at the same time and only 10 proteins were found to be common in all cell lines. These 10 proteins are shown in the middle of the Venn diagram (alpha 2-HS glycoprotein, inter-alpha-trypsin inhibitor heavy chain 2, FUS RNA binding protein, mechanistic target of rapamycin, SUB1 homolog transcriptional regulator, Y-box binding protein 1, serine and arginine rich splicing factor 2, testis specific 10 interacting protein, sperm associated antigen 5 and heterogeneous nuclear ribonucleoprotein A/B). A complete list of all proteins identified is provided in Additional file 3: Table S2
