LncRNA PTOV1-AS2 Promotes Colon Cancer Progression through the miR-145-5p/FSCN1 Axis

Figure 3

PTOV1-AS2/miR-145-5p axis affects the expression of FSCN1 (a) Bioinformatics analysis predicted that miR-145-5p can bind the 3′-UTR region of both PTOV1-AS2 and FSCN1. (b) Dual luciferase assay confirmed the target binding of PTOV1-AS2 and miR-145-5p. (c, e) Measurement of miR-145-5p (c) and FSCN1 (e) expression in colon cancer tissues by qRT-PCR analysis. (d) Dual luciferase assay to verify the targeted binding of miR-145-5p to the FSCN1 3′-UTR region. (f) Analysis of the regulation of the protein expression levels of FSCN1 by PTOV1-AS2/miR-145-5p axis by western blot analysis.
