CNPY2 and neoplasm: The expression of miR-545-5p and CNPY2 in tumor tissues was assessed and the results showed that knockdown of LINC00342 significantly increased the expression levels of miR-545-5p (p < 0.01) and reduced the expression levels of CNPY2 (p < 0.01) in tumor tissues compared with negative control sh-NC (Fig. 7e and f).
