Tracking Evidences of Dandelion for the Treatment of Cancer: From Chemical Composition, Bioactivity, Signaling Pathways in Cancer Cells to Perspective Study.

Cancer has become the second leading cause of death globally and is a big threat to human health. The development of new anticancer drugs and the elucidation of the signaling pathways of bioactive compounds are still effective strategies to address the current challenges in the clinical treatment of cancer. Dietary compounds are composed of a variety of effective ingredients, which have become an important source for the development of novel candidates for the treatment of cancer. These bioactive ingredients often carry the characteristics of low side effects, multi-target, and economic savings and hence attract more and more scholars' research interests in them. Dandelion, one of the important medicinal and edible plants, is effective in anticancer, inhibition of bacterial growth, hypoglycemic, and anti-inflammation, as well as antioxidant. Growing evidences from modern pharmacological research demonstrate the notable anticancer effects of dandelion. Bioactive components from dandelion are effective in inhibiting the occurrence and progression of various cancers, such as breast, lung, and liver cancers. Hence, the chemical composition, anticancer activities, and signaling pathways in cancer cells treated with bioactive components from dandelion are summarized in this review. We aim to provide more pharmacological evidence and scientific references for further research and development of dandelion for cancer treatment. Meanwhile, we anticipate that some novel candidates with high efficacy and low toxicity for anticancer might be developed from dandelion in future research on this plant.
