🍓🔬 Researchers tested an anthocyanin-rich crude extract made from cultivated strawberries (Fragaria × ananassa) on B16-F10 mouse melanoma cells grown in a laboratory. The strawberry extract reduced the cells’ ability to multiply and lowered levels of polyamines, substances involved in cell growth. It also increased the activity of tissue transglutaminase, a marker associated with cancer cells becoming more differentiated and potentially less aggressive.
The treatment also changed the expression of many proteins inside the melanoma cells: 30 proteins increased, while 87 decreased. Several proteins linked to tumor progression, cancer metabolism, and the rapid energy production used by cancer cells were reduced. However, this was an experiment on mouse melanoma cells in a laboratory, not a study involving animals or people, so it does not show that eating strawberries or taking strawberry extract can treat skin cancer.
