Correspondingly, CCDC181 (normalized TPM count = −0.094, p < 0.1) (Figure 4a), OR4F29 (normalized TPM count = −0.005, p < 0.1) (Figure 4b), and ID4 (normalized TPM count = −58.839, p < 0.001) (Figure 4c), were downregulated in tumor samples (n = 1094) while, MKI67 (normalized TPM count = 9.94, p < 0.001) and SPOCK1 (normalized TPM count = 3.26, p < 0.001) were found to be over-expressed in tumor samples but not OPCML (Figure 4d–f). This evidence concerns the gene CCDC181 and neoplasm.
