Western blot showed that the protein expression levels of FSTL3, Vimentin, N-cadherin, MMP2 and MMP-9 in the mice tumor tissue in the sh-LBX2-AS1 experimental group were decreased (Figure 6C), indicating that FSTL3 expression was increased at protein level and EMT was promoted. Here, FSTL3 is linked to neoplasm.
