Rhodiola crenulata induces death and inhibits growth of breast cancer cell lines.

Diverse compounds from many different chemical classes are currently targeted in preclinical analyses for their ability to act as both chemopreventive and chemotherapeutic agents. Phenolic phytochemicals from Rhodiola crenulata has such potential. This Rhodiola species is a perennial plant that grows in the Tundra, Siberia, and high-elevation regions of Tibet. The phenolic secondary metabolites isolated from R. crenulata were recently analyzed in a preclinical setting for their ability to treat lymphosarcomas and superficial bladder cancers. However, the effects of R. crenulata have yet to be examined for its implications in breast cancer prevention or for its chemotherapeutic abilities. Therefore this study investigated the effects of R. crenulata on breast cancer both in vivo and in vitro. Experiments using aggressive human-derived MDA-MB-231 and mouse-derived V14 breast cancer cell lines demonstrated that phenolic-enriched R. crenulata extract was capable of inhibiting the proliferation, motility, and invasion of these cells. In addition, the extracts induced autophagic-like vesicles in all cell lines, eventually leading to death of the tumor cell lines but not the immortal or normal human mammary epithelial cells. Finally, an in vivo experiment showed that phenolic-enriched dietary R. crenulata is effective in preventing the initiation of tumors and slowing down the tumor growth in mice bearing tumor grafts, thereby further demonstrating its possible potential for treatment of breast cancer progression and metastasis.

The paper presents a review of the scientific publications on Rhodiola rosea L. known for its adaptogenic characteristics. Biologically active substances salidroside, rosin, rosavin, rosarin and tyrosol, which are mainly found in plant rhizomes, demonstrate therapeutic effect. These active components effect the central nervous system by increasing the ability to concentrate, the mental and physical power; they are efficient in the asthenic states and improve general resistance of the cells and the organism against the harmful outer influence. They also prevent the heart system from stress and arrhythmias, and posses some antioxidant activity. Some data confirm that the Rhodiola rosea L. preparations stop the growth of the malignant tumors and metastases in the liver. Some preclinical and clinical data of the golden root preparations are discussed in the survey. The interaction of the herb with other medicines, its usage and effect, recommended doses, and its side effects are also reviewed in the paper.
