In order to prioritize the recurrent tumor-associated candidate proteins for assessment of their roles in chemoresistance in vitro, we selected 11 genes validated by RT-PCR including CP, STAT5B, FN1, CD97, RELA (NF-κB p65), AIF1, SYK, WNK1, URP2, SERPINA3 and APOD because they were upregulated in at least 2 out of 3 pairs of carboplatin-resistant cells. Here, CP is linked to neoplasm.
