LINC00961 inhibits the migration and invasion of colon cancer cells by sponging miR ‐223‐3p and targeting SOX11

This study aimed to explore the potential function and molecular mechanisms of LINC00961 in colon cancer. qPCR results showed that LINC00961 was downregulated in colon cancer cells and tissues. Functional assays demonstrated that LINC00961 suppressed the migration and invasion of colon cancer cells in vitro. LINC00961 functioned as an endogenous sponge for miR ‐223‐3p in colon cancer cells. SOX11 was confirmed as a target gene of miR‐223‐3p. The effect of miR‐223‐3p on colon cancer cells was then investigated. MiR‐223‐3p inhibition enhanced their migration and invasion. The effect of SOX11 on colon cancer cells was studied. SOX11 overexpre ssion inhibited the invasion of colon cancer cells. LINC00961 acted as an anti‐oncogene and upregulated SOX11 expression by functioning as a miR‐223‐3p sponge. This research revealed the molecular mechanism of LINC00961 in colon cancer. LINC00961 might act as a potential diagnostic biomarker a nd therapeutic target for further clinical treatments.
