Specifically, one study has demonstrated that the long noncoding RNA LINC00675 exerts oncogenic effects by binding to miR‐6809, thereby preventing it from suppressing the expression of CDK6—a key regulator of cell proliferation. The sequestration of miR‐6809 by LINC00675 leads to increased CDK6 levels, promoting malignant cell growth and survival, while also correlating with elevated expression of immune-checkpoint genes. This interaction not only enhances AML malignancy by reducing apoptosis but also suggests that targeting the LINC00675/miR‐6809/CDK6 axis could offer new avenues for therapeutic intervention."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "4"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nCollectively, these findings position miR‐6809 as a tumor‐suppressive microRNA whose regulatory activity—primarily through the inhibition of CDK6 expression—is compromised in AML due to its sponging by LINC00675.
