Owoce maliny czarnej (Rubus occidentalis L.) w profilaktyce i terapii niektórych chorób nowotworowych – aktualny stan badań

Abstract

Black raspberry (Rubus occidentalis L.) is a plant found in the natural state in eastern North America. In recent years, there has been growing interest in its fruits, mainly due to the results of scientific research, pointing to the health benefits associated with their consumption. Research concerning biological activity of black raspberry fruit includes chemopreventive activity, protective activity against UV radiation, mainly in the context of generating cancerous changes as well as inhibiting their development. Persistent oxidative stress and its accompanying inflammation result in disturbances in the structure and function of healthy cells, and may be related to neoplastic transformation, manifested by DNA damage, increased proliferation, survival, migration and angiogenesis. Numerous in vitro and in vivo studies as well as clinical trials confirm the chemopreventive activity of R. occidentalis fruits in va-rious types of cancer. This activity includes regulation of carcinogenic factors metabolism, inhibition of cell growth, promotion of apoptosis and reduction of expression of inflammation and angiogenesis markers. The chemopreventive activity of R. occidentalis fruit results, among other things, from the high content of anthocyanins, which are one of the strongest antioxidants.
