Rhein Augments Antiproliferative Effects of Atezolizumab Based on Breast Cancer (4T1) Regression
Planta Med DOI: 10.1055/a-1012-7034Rhein, an anthraquinone extracted from rhubarb, is used in traditional Chinese medicine for diuresis, diarrhoea, inflammation, and immune regulation. Atezolizumab, a programmed cell death ligand 1 monoclonal antibody, is mainly used to treat bladder cancer and non-small cell lung cancer unresponsive to chemotherapy. We explored the effects of rhein and atezolizumab in combination on breast cancer. Mice with established 4T1 breast cancer xenografts were administered rhein (10 mg/kg) and atezolizumab (10 mg/kg), alone and in combination, and the effects on tumour growth were evaluated. The proportion of CD8+ T cells in the spleen and tumour tissue, the levels of TNF-α, and interleukin-6 in serum as well as the mRNA levels of apoptotic factors (caspase-3, caspase-8, caspase-9, and Bax/Bcl-2) were also evaluated. All of the treatment groups had inhibitory effects on the xenograft tumour growth, with results that were significantly different from those in the control group. In addition, the proportion of CD8+ T cells in the spleen and tumour was significantly increased in the combination therapy group and was significantly different from the other treatment groups. The serum levels of TNF-α and IL-6 were significantly increased in the rhein and combination therapy groups. Finally, the levels of various apoptotic factors in tumour tissues were significantly higher in the combination treatment group than those in the other groups. A...
