Although numerous pathways are known to control the tumor suppressor protein p53, coordinated regulation of the p53–Notch axis by Numb may have an even more remarkable impact. In this issue, Colaluca at al. (2018. J. Cell Biol. https://doi.org/10.1083/jcb.201709092) reveal an unexpected role of a newly characterized Numb splice variant in the regulation of p53, which may have significant implications for therapeutic intervention in breast cancer.

Purpose: To produce an anti-cancer agent from Physalis minima ethanol extract as well as prevent the growth of NMU-induced breast cancer and MCF-7 cell line.Methods: This research used an animal model (Wistar-Furth rats), and cell line used in this study was normal breast-cell line MCF-7. The rats were administered with the ethanol extract of Physalis minima Linn (100, 250 and 400 mg/kg/day) by gavage, once a day for 4 weeks. Meanwhile, MCF-7 cell lines were cultured in medium and incubated in 100 μg/mL of ethanol extract of Physalis minima for 48 h. The samples were analyzed using histology and immunohistochemistry techniques for expression of p53 antibody DO-1 and APAF-1.Results: The results of immunohistological analysis in the breast organ showed that Physalis minima Linn extract significantly (p < 0.05) increased the tumor suppressor protein p53 at doses of 100, 250 and 400 mg/kg/day. In addition, the extract also significantly (p < 0.05) increased APAF-1, which is a gene determining cell death, at doses of 100, 200 and 400 mg/day.Conclusion: Ethanol extract of Physalis minima Linn inhibits the cytotoxic activity of NMU-induced breast cancer by increasing the tumor suppressor protein p53 and APAF-1. Thus, Physalis minima Linn extract can potentially be used as a complementary treatment for inhibiting the growth of breast cancer cells in patients.
