FOXF1 and neoplasm: It was shown that the mRNA expression levels of LINC00022 and FOXF1 in tumor tissues were significantly increased by the injection of LINC00022 overexpressing cells (4.9–7.8 fold vs Lv-NC group) and decreased by the injection of LINC00022 low-expressing cells (0.3–0.5 fold vs Lv-anti-NC group, Fig. 8c).
