The co-expressed genes were identified by two criteria as follows: (a) The expression of these genes needs to have a strong correlation with CAV1/CAV2 expression (|Pearson’s R| ≥ 0.60) in normal and tumor tissues; (b) if their expression was positively correlated with CAV1/CAV2′s, the expression levels of these genes need to have a significant difference between normal samples and tumor samples (Welch’s t-test, p < 0.05). Here, CAV2 is linked to neoplasm.
