Andrographis and Melatonin Stop Colon Cancer Cells

Despite advances in detection and treatment, colon cancer is still a leading cause of death from cancer. Chemotherapy treatment, primarily using 5-fluorouracil (5FU), is limited by its toxicity to both the cancer and the patient, so finding other methods to stop tumors is imperative.

Fortunately, leading edge research has reported that Andrographis paniculata, an adaptogenic herb used in traditional Ayurvedic practice, along with melatonin, can be a powerful ally in the fight against cancer.

While melatonin is generally regarded for its relationship to sleep cycles, it affects virtually every cell in the body and is involved with inflammatory responses, immune system strength, and DNA integrity.

Colon cancer cell research found that andrographis and melatonin inhibited cancer cell replication and induced a process in which cancer cells degrade and ultimately die, called “autophagy.” While each nutrient was tested against cancer cells, andrographis and melatonin worked more effectively as a team than either one alone – although each ingredient showed remarkable efficacy when used by itself, as well.

When searching for andrographis in supplement form, it is important to make sure it has been standardized for 20 percent andrographolide – a key component in the herb considered most responsible for its many beneficial effects.

Abstract:

Zhao Y, Wang C, Goel A. A combined treatment with melatonin and andrographis promotes autophagy and anti-cancer activity in colorectal cancer. Carcinogenesis. 2022 Jan 28:bgac008. doi: 10.1093/carcin/bgac008. Epub ahead of print. PMID: 35089340.

Colorectal cancer (CRC) is one of the most frequent malignancies worldwide and remains one of the leading causes of cancer-related deaths in the United States. The high degree of morbidity and mortality associated with this disease is largely due to the inadequate efficacy of current treatments as well the development of chemoresistance. In recent years, several pharmaceutical agents screened from natural products have shown the promise to offer a safe, inexpensive, and synergistically multi-targeted treatment option in various cancer. Given the growing evidence of anti-carcinogenic properties of two natural compounds, melatonin (MLT) and andrographis (Andro), we aimed to evaluate their synergistic anti-cancer effects in CRC. We demonstrate that indeed these two compounds possessed a synergistic anti-cancer effect in terms of their ability to inhibit cell viability, suppression of colony-formation and induction of apoptosis (p<0.05). In line with our in-vitro findings, we were able to validate this combinatorial anti-cancer activity in xenograft animal models (p<0.001) as well as tumor-derived 3D organoids (p<0.01). RNA-sequencing analysis revealed candidate pathways and genes that mediated anti-tumor efficacy of MLT and Andro in CRC, among which autophagy pathway and related genes, including NR4A1, CTSL and Atg12, were found to be primarily responsible for the increased anti-cancer effect by the two natural products. In conclusion, our data reveal a potent and synergistic therapeutic effect of MLT and Andro in the treatment of CRC and provides a rationale for suppressing autophagy in cancer cells as a potential therapeutic strategy for CRC.
