Enzyme activity of neuraminidase 1 correlated with the biological behavior of prostate cancer PC3 and DU145 cell lines

Objective To investigate the effects of the enzyme activity of neuraminidase 1 (Neu1) on the biological behavior of prostate cancer PC3 and DU145 cell lines. Methods We detected the expression of Neul in the prostate cancer PC3 and DU145 cell lines by Western blot. Using sialidase inhibitors and antibody blocking, we suppressed the enzyme activity of Neu1 and then measured the proliferation and invasiveness of the two cell lines by CCK-8 and Transwell assay, respectively. Results No statistically significant difference was found in the Neu1 expression between the PC3 and DU145 cell lines. The proliferation and invasiveness of the two types of cells were both increased after inhibition of the Neu1 enzyme activity. Conclusions The enzyme activity of Neu1 is correlated with the biological behavior of prostate cancer PC3 and DU145 cells and capable of inhibiting the proliferation and invasiveness of the two types of cells.
