Specific fractions of Lycium barbarum, commonly known as Goji berry, reduce heart and kidney damage caused by anthracyclines while possibly enhancing their therapeutic effects.
The study investigated the effects of three different fractions of Goji berries (pectin-free, polysaccharides, and a mix of the two) on rat models suffering from doxorubicin-induced damage to the heart and kidneys. The fractions were orally administered at a dose of 2mg/kg while doxorubicin was applied at a total dose of 20mg/kg. Several biomarkers were used to assess heart damage (such as creatine kinase, aspartate aminotransferase, lactate dehydrogenase) and kidney damage (creatinine, blood urea nitrogen, uric acid), along with potassium serum levels. Additionally, a histological analysis of the hearts and kidneys was conducted.
In terms of results, rats treated solely with doxorubicin exhibited a significant increase in all toxicity biomarkers. However, in all groups that also received any of the plant fractions, there was substantial reduction in markers indicating heart and kidney tissue damage. Notably, the pectin-free and combined fractions presented the most substantial decreases in toxicity indicators. These findings were further corroborated by the histological analysis.
