In this study, Taiwanese researchers investigated the effects of a new Traditional Chinese Medicine (TCM) formula, T33, on breast cancer cells in vitro and in vivo. Their findings were published in the journal BMC Complementary and Alternative Medicine.
- Breast cancer is the leading cause of cancer-related deaths in women worldwide.
- Although TCM is commonly used by breast cancer patients, little is known about TCM prescriptions for breast cancer.
- T33 is a new TCM formula that consists of Radix Kansui, Rheum rhabarbarum, Paeonia lactiflora, jiang ban xia and zhi gan cao.
- To evaluate its effects on human breast cancer, the researchers treated cell lines (HMEpiC, MDA-MB231 and MCF-7 cells) with different concentrations of T33.
- They then analyzed its biological properties using MTT and Transwell migration assays.
- To determine the involvement of autophagy in T33-induced death of MDA-MB231 and MCF-7 cells, the researchers used immunofluorescence staining with LC3-II-specific antibodies.
- They also generated tumor xenografts by injecting either MDA-MB231 or MCF-7 cells subcutaneously into mice.
- The researchers found that low (0.1?mg/mL) and high (10?mg/mL?) concentrations of T33 significantly inhibited the proliferation and invasion of cancer cells.
- Treatment with 2.5?mg/mL, 5?mg/mL and 10?mg/mL?T33 also induced significant autophagy.
- In vivo, both low (200?mg/kg) and high (600?mg/kg) doses of T33 inhibited the proliferation of xenografted breast cancer cells in nude mice.
Based on these findings, the researchers concluded that T33 has potential as a treatment for breast cancer because of its anti-proliferative and autophagy-promoting activities.
