Abstract

Aim Of The Study: To investigate the effects of mast cells on the proliferation, invasion, and metastasis of prostate cancer cells.

Material And Methods: The mast cell P815 and prostate cancer LNCaP cells were chosen using a Transwell chamber to construct a two-cell cocultured in vitro model to observe the migration of mast cells to prostate cancer cells.

Results: In the migration experiment, the migration rate of mast cells from the experimental group (%) was 10.167 0.833, the mast cell migration rate (%) of the control group was 0.833 0.208, and the difference was statistically significant (p < 0.05). The MTT test showed that the OD value of cells in each group over time increased gradually, and 24 h after LNCaP cells were cocultured with different concentrations of mast cells, the OD value was significantly higher than that of the control group (p < 0.05). QRT-PCR and western blot results showed that, compared with the control group, E-cad expression from the experimental group was significantly weakened; N-cad and vimentin expression increased (p < 0.05), and c-kit and SCF expression from experimental group were significantly higher than that of the control group (p < 0.05). After the addition of c-kit neutralising antibodies, compared with the control group, the mast cell migration rate of experimental group decreased significantly and prostate cancer cell proliferation significantly decreased (p < 0.05).

Conclusions: Mast cells could promote the proliferation of prostate cancer cells and the occurrence of epithelial mesenchymal transition (EMT), which could promote the invasion and metastasis of prostate cancer cells.
