On the other hand, in the protein expression profile of SSC-2, the neoplastic proliferation of tumor cells was related to the overexpression of PCNA, MPM2, KRAS, STAT3, EGFR, and bFGF and was supported by the overexpression of the protein translation factors eIF5A, DHS, and DOHH compared to SSC-1. This evidence concerns the gene PCNA and neoplasm.
