Conversely, NR2F1-AS1 acts as a tumor suppressor in colorectal cancer by sponging miR-371a-3p, leading to increased TOB1 expression and subsequent inhibition of proliferation in RKO cells [50] Similarly, in cervical squamous cell carcinoma, it suppresses proliferation by interacting with miR-17 to enhance SIK1 expression [51]. Here, NR2F1 is linked to colorectal cancer.
