BDNF and neoplasm: The expression of BDNF-AS, miR-125a-5p, and miR-125b-5p in tumor tissues were detected by qRT-PCR, and the results showed that BDNF-AS was significantly downregulated (p < 0.001), while miR-125a-5p and miR-125b-5p in tumor tissues were markedly upregulated in sh-BDNF-AS injected mice compared with that in sh-NC injected mice (p < 0.01, Fig. 8E and F).
