dc.description.abstractAspirin, formally known as acetylsalicylic (ASA), is most widely used and cheapest over-the counter drugs. It is used not only for the common fevers, headaches and inflammation, but also for reducing the risk of heart attacks. In recent years, it is also linked to anti-cancer potential. Recently the US Preventive Services Working Group (UPSTF) release aspirin as a guide for cardiovascular disease and primary prevention of colorectal cancer. Platelets have been shown to play a crucial role in cancer metastasis for many years and are proposed to have an intimate reciprocal crosstalk with cancer cells. They may alter the properties of each other and have reciprocal effects. But the exact role of platelets in modifying the tumor cell properties has not been established. In clinical, cancer patients may receive platelets from outside to treat thrombocytopenia and bleeding induced by intensive chemotherapy. Therefore understanding the exact role of platelets in carcinogenesis always is a research interest, especially when evaluating anti-cancer drugs. In this study we exam the effect of platelets on viability, proliferation and adhesion of lung cancer cells A549 in culture conditions, using different concentrations of platelet rich plasma (PRP) with and without the presence of antiplatelet drug aspirin. The tumor cell EMT transformation was also investigated under different combination of PRP and aspirin in vitro. Our data showed that low-dose of aspirin can promote cell proliferation and high-dose of aspirin could inhibit cell proliferation. High concentrations of platelet-rich plasma can inhibit cell proliferation but low concentrations of platelet-rich plasma had no significant effect on cell proliferation. Platelet-rich plasma can gather around the cell to form a gelatinous film, and this lead us to a promoted tumor cell distant metastasis model. We further found out that the combination of aspirin and PRP could increase cell viability compared to single use of PRP and Aspirin can affect cell proliferation by inhibiting platelet effects. Platelet-rich plasma reduces the adhesion of A549 cell can be attenuated by aspirin. Further works will focus on combination of different doses of aspirin and PRP to confirm the above results. Other format of aspirin (nano-form) and other NSAID inflammatory drugs like Ibuprofen will also be tested.en_US
