In contrast, EPYC was not detected in healthy tissues, although low levels of expression were found in about 40% of tumor samples (Figure 1A) and, interestingly, while high levels of RNA encoding OGN were present in healthy tissue, the mean of the differences in the transcription levels between the healthy and tumor tissue samples from each patient showed that the transcription levels of this gene in tumor tissues were around 13% of those in healthy tissues (p < 0.05, Wilcoxon test, Figure 1B). Here, OGN is linked to neoplasm.
