Further, Western blot analysis showed reduced expression of FOXP3, Ki67, CyclinD1, VEGF and Brachyury in mouse xenograft tumours transduced with oe‐LINC00261, while SCP2 expression was notably upregulated; silencing LINC00261 resulted in the opposite effects, and the effect of LINC00261 overexpression could be abrogated by upregulating FOXP3 or depleting SCP2 (Figure 5E,F). Here, FOXP3 is linked to neoplasm.
