Although bioinformatics analysis indicated a positive correlation between the mRNA expression of DCLK1 and YAP1 in tumor samples (Figure 2A), there were no significant changes in the mRNA or protein expression levels of YAP1 in PCa cell lines after DCLK1 overexpression or knockdown at the cellular level (Figure 3A). This evidence concerns the gene YAP1 and neoplasm.
