Expression correlation between TMPO-AS1 (or let-7c-5p) and BCAT1. A PCR analysis of BCAT1 level in NPC tissue and adjacent normal tissue. B-C PCR and western blot analyses were performed to measure BCAT1 expression in NPC cells and normal human nasopharyngeal cell line (NP69). D-E PCR and western blot analyses of BCAT1 mRNA and protein levels in NPC cells silencing TMPO-AS1. The expression correlation (F) between TMPO-AS1 and BCAT1 and that (G) between let-7c-5p and BCAT1 in NPC tissue was analyzed using Spearman’s correlation coefficient. *p < 0.05, **p < 0.01, ***p < 0.001
