To more fully assess the function of ITK in ovarian cancer, we furtherly performed correlation analysis and found that the ITK expression was positively correlated with 359 genes (including cancer suppressor gene CD244 and SOCS1, r > 0.3) and negatively associated with 81 genes (including oncogene SMARCD1, r < − 0.3). Here, SMARCD1 is linked to ovarian cancer.
