Abstract:

Objective To identify the effect of aspirin on epithelial-mesenchymal transition, migration and invasion in MCF-7 cells induced by activated platelets. Methods MCF-7 cells were treated with different concentrations of aspirin, platelets activated with arachidonic acid, and different concentrations of aspirin combined platelets activated with arachidonic acid, respectively. Scratch test and transwell test were used to determine the capacities of migration and invasion. Meanwhile, the expression of E-cadherin and Vimentin which linked to epithelial-mesenchymal transition (EMT) was measured by Western Blot. Results After the intervention of activated platelets, the migration and invasion capabilities of MCF-7 cells were enhanced (P<0.05). The expression of E-cadherin was decreased and Vimentin was increased obviously. After the treatment of low and high concentration aspirin combined with platelets, the migration and invasion capabilities were decreased compared with the group which was treated only with activated platelets(P<0.05). The expression of E-cadherin was elevated and Vimentin was obviouslt reduced. When MCF-7 cells were treated with low concentration (0.5 mmol/l) and high concentration (2.0 mmol/l) of aspirin only,there was no significant difference in the migration and invasion capabilities(P>0.05) compared with the control group without intervention. Meanwhile, Western Blot showed no obvious changes in the expression of E-cadherin and Vimentin (P>0.05). Conclusion Results in vitro experiments indicated that aspirin could inhibit the abilities of epithelial-mesenchymal transition (EMT), migration and invasion in MCF-7 cells through suppressing the activation of platelets.
