We analyzed the mRNA level of tumor-associated genes such as Cadherin-1, Ki-67, PCNA, β-catenin, STAT3, and COX2 (Figure 6A), as well as the protein levels of tumor marker VEGF, its downstream transcription activator STAT3 and p-STAT3, and the tumor proliferation marker PCNA (Figures 6B–D). Here, PCNA is linked to neoplasm.
