This thesis aimed to review the effects of quercetin on the adhesion and cell division of metastatic uveal melanoma cells. Uveal melanoma (UM) is a rare but lethal type of cancer which affects the uvea of the eye. The treatment options used nowadays are invasive and UM is a chemoresistant type of cancer. For these reasons, there is a dire need for more stable and less invasive options. Quercetin is a dietary flavonoid which is known for its numerous health-promoting benefits, due to its favorable properties such as its antioxidant, anti-inflammatory, and cancer-fighting properties.
