Zhao et al. [17] found that LINC00665 was significantly upregulated in colorectal cancer tissues, which was negatively correlated with miR-9-5p expression but positively associated with ATF1 expression; and LINC00665 overexpression resulted in apparent enhancements in cell proliferation, migration, and invasiveness and reduced cell apoptosis by targeting miR-9-5p to increase ATF1 expression in colorectal cancer. Here, LINC00665 is linked to colorectal cancer.
