Berberine inhibits the development of endometrial cancer through circ_ZNF608/miR-377-3p/COX2 axis.
Objective: Endometrial carcinoma (EC) is a common malignant tumour in women. Berberin (BBR) is an alkaloid with anti-tumour activity, and circular RNA (circRNAs) has been extensively studied in cancers. However, whether BBR regulates the development of EC by regulating circular RNA zinc finger protein 608 (ZNF608) is unknown.
Methods: Different concentrations of BBR were used to treat endometrial cancer cells. A quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to assess the expression of circ_ZNF608, microRNA-377-3p (miR-377-3p) and cyclooxygenase 2 (COX2). The expression of COX2 protein was detected by western blot. The effect of circ_ZNF608 in BBR-treated EC cells was verified by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, thymidine analog 5-ethynyl-2'-deoxyuridine (EdU) assay, colony formation assay, transwell, and flow cytometry. The effect of BBR and circ_ZNF608 on tumour growth was evaluated by xenograft tumour model in vivo.
Results: Berberine can inhibit the proliferation and metastasis of EC cells and promote apoptosis, which is related to the concentration. Circ_ZNF608 and COX2 were abnormally increased, while the levels of miR-377-3p were reversed in EC tissues and cells. Overexpression of circ_ZNF608 can restore the inhibitory effect of BBR on EC cells. In addition, circ_ZNF608 restored the inhibitory effect of BBR on EC cells by inhibiting the expression of miR-377-3p. Similarly, MiR-377-3p/COX2 can regulate the tumour progression of EC under BBR. Finally, BBR can inhibit the growth of endometrial carcinoma in vivo.
Conclusion: BBR was found to inhibit EC via the circ_ZNF608/miR-377-3p/COX2 axis, which is helpful in endometrial carcinoma.
期刊介绍：
Autoimmunity is an international, peer reviewed journal that publishes articles on cell and molecular immunology, immunogenetics, molecular biology and autoimmunity. Current understanding of immunity and autoimmunity is being furthered by the progress in new molecular sciences that has recently been little short of spectacular. In addition to the basic elements and mechanisms of the immune system, Autoimmunity is interested in the cellular and molecular processes associated with systemic lupus erythematosus, rheumatoid arthritis, Sjogren syndrome, type I diabetes, multiple sclerosis and other systemic and organ-specific autoimmune disorders. The journal reflects the immunology areas where scientific progress is most rapid. It is a valuable tool to basic and translational researchers in cell biology, genetics and molecular biology of immunity and autoimmunity.
