Figure 3. lncRNA TTN-AS1 targeted miR-134-5p. (A) The website predicted that lncRNA TTN-AS1 targeted miR-134-5p. (B) QPCR was used to detect the expression level of miR-134-5p in tumour tissues and adjacent tissues. (C, D) The effects of downregulation or upregulation of lncRNA TTN-AS1 on miR-134-5p are shown. (E, F) The effects of downregulation or upregulation of miR-134-5p on lncRNA TTN-AS1 are shown. (G, H) The effects of transfected mutant lncRNA TTN-AS1 on miR-134-5p are shown. *P < 0.05 vs. normal tissue or vector-NC.
