Anti Tumour Effect

Background: Cepharanthine (CEP) is a biscoclaurine alkaloid extracted from Stephania cepharantha and has been shown to have an anti-tumour effect on different types of cancers. However, the anti-cancer effect of CEP on human breast cancer cells is still unclear. Methods: We used MTT, clone formation, in vitro scratch, invasion and migration assays to confirm the inhibitory role of CEP on the proliferation of breast cancer cells. Flow cytometry, plasmid construction and western blot analysis were used to study the detailed mechanisms. Results: Our study showed that CEP could inhibit cell proliferation by inducing autophagy, apoptosis, and G0/G1 cell cycle arrest of breast cancer cells. Furthermore, we found that CEP induced autophagy and apoptosis by inhibiting the AKT/mTOR signalling pathway. Conclusion: We found that CEP could inhibit growth and motility of MCF-7 and MDA-MB-231 breast cancer cell. Our study revealed an anti-tumour effect of CEP on breast cancer cells and suggests that CEP could be a potential new clinical therapy for breast cancer.

Piperlongumine (PL), a natural product derived from long pepper (Piper longum L.), is known to exhibit anticancer effects. However, the effect of PL on cell cycle-regulatory proteins in estrogen receptor (ER)-positive breast cancer cells is unclear. Therefore, we investigated whether PL can modulate the growth of ER-positive breast cancer cell line, MCF-7. We found that PL decreased MCF-7 cell proliferation and migration. Flow cytometric analysis demonstrated that PL induced G2/M phase cell cycle arrest. Moreover, PL significantly modulated the mRNA levels of cyclins B1 and D1, cyclin-dependent kinases 1, 4, and 6, and proliferating cell nuclear antigen. PL induced intracellular reactive oxygen species (hydrogen peroxide) accumulation and glutathione depletion. PL-mediated inhibition of IKKβ expression decreased nuclear translocation of NF-κB p65. Furthermore, PL significantly increased p21 mRNA levels. In conclusion, our data suggest that PL exerts anticancer effects in ER-positive breast cancer cells by inhibiting cell proliferation and migration via ROS accumulation and IKKβ suppression.
