Breast Cancer

Human breast cancers cells overexpressing HER2/neu are more aggressive tumours with poor prognosis, and resistance to chemotherapy. A study by Gang et aL., (2012) investigates anti-proliferation effects of anthraquinone derivatives of rhubarb root on human breast cancer cells. Of 7 anthraquinone derivatives, only rhein showed anti-proliferative and apoptotic effects on both HER2-overexpressing MCF-7 (MCF-7/HER2) and control vector MCF-7 (MCF-7/VEC) cells. Rhein induced dose- and time-dependent manners increase in caspase-9-mediated apoptosis correlating with activation of ROS-mediated activation of NF-κB- and p53-signaling pathways in both cell types. Therefore, this study highlighted rhein as processing anti-proliferative activity against HER2 overexpression or HER2-basal expression in breast cancer cells and playing important roles in apoptotic induction of human breast cancer cells (2).*

Rhein significantly increased the expression of cytochrome c and apoptotic protease activating factor 1, two critical components involved in mitochondrial pathway-mediated apoptosis. Li et al., (2012) conclude that rhein inhibits gastric inhibits cancer cell line (SGC-7901) proliferation by inducing apoptosis and this anti-tumuor effect of rhein is mediated in part by an intrinsic mitochondrial pathway (3).*

Results showed that rhein remarkably inhibited breast cancer SK-Br-3 cell proliferation. The protein expressions of HER-2, NF-KB, and the protein phosphorylation of HER-2 were downregulated, however the protein expression of p53 and p21 was upregulated after rhein treatment. The level of HER-2 mRNA decreased by using RT-PCR assay and the level of HER-2 expression was also decreased by using immunofluorescence cytochemical assay after rhein treatment. It can be concluded that rhein could inhibit SK-Br-3 cell proliferation and induce apoptosis. HER-2/NF-kappaB/p53/p21 signal pathway might be involved in this process (4).*

Hypoxia is a hallmark of solid tumors, including breast cancer, and the extent of tumor hypoxia is associated with treatment resistance and poor prognosis. Considering the limited treatment of hypoxic tumor cells and hence a poor prognosis of breast cancer, the investigation of natural products as potential chemopreventive anti-angiogenic agents is of paramount interest. Rhein inhibits angiogenesis and the viability of hormone-dependent (MCF-7) or -independent (MDA-MB-435s) breast cancer cells in vitro under normoxic or hypoxic conditions.*

Rhein inhibited the expression of hypoxia-inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF165), epidermal growth factor (EGF), and the phosphorylation of inhibitor of NF-κB (I-κB) under normoxic or hypoxic conditions. Taken together, these data indicate that rhein is a promising anti-angiogenic compound for breast cancer cell viability and growth (5).*      

Rhein the Anti-Bad blocks the uptake of glucose in tumour cells, causing changes in membrane associated functions to trigger cell death (6).*

Rhein, a major compound in rhubarb, has been found to have anti-tumor properties in many human cancer cells. Ge et al., (2011) explored the potential of rhein as a chemotherapeutic agent on HCT- 116 cells and demonstrated significant inhibition of HCT-116 cells proliferation in both concentration (0, 10, 30, and 100 µM) and time (24, 48, and 72 h) dependent manners. The anti-tumor effects were associated with the introduction of cellular apoptosis, which was relative with reduction of Bcl-2, NF-κB and activation of caspase-9 and 3. These findings suggested that rhein inhibited the growth of HCT-116 through the intrinsic apoptotic pathway and might be a useful strategy of chemo- therapeutics of colon cancers.*

Rhein had exerted cytotoxicity on human colon carcinoma HCT-116 cells, mainly through Bcl-2/BAX and NF-κB mediated caspase-activated apoptotic pathway and rhein has the potential to be developed as a chemotherapeutic or adjuvant agent on human colon cancers (7).*


Rhein has been used in traditional Chinese medicine with putative antidiabetic effects. Here we show that oral administration of Rhein for 6 weeks can significantly reduce fasting blood glucose (FBG) level, elevate the active glucagon-like peptide 1 (GLP-1) level, and increase the number of L-cells in the terminal ileum. Wang et al., (2018) demonstrate that results indicate the modulation of the gut microbiota may play an essential role in the antidiabetic effects of Rhein. Enteroendocrine cells (L Cells) are specialised cells of the gastrointestinal tract and pancreas with endocrine function. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect.*

These findings by Wang raise the possibility that gut microbiota play an essential role in the antidiabetic effects of Rhein. In this study, we focus on how Rhein regulates gut microbiota and how it contributes to the enteroendocrine function. Taken together, their study shows that oral administration of Rhein can significantly reduce the level of FBG and elevate GLP-1 (8).*
