ANXA5 and breast cancer: This study aims at investigating the anticancer role of NaB and NaP in different types of breast cancer by assessing their antiproliferative effect on MCF-7 and MDA-MB-231 cells (through an MTT assay), as well as their ability to alter the cell cycle and cyclin expression (using flow cytometry and RT-qPCR, respectively), and to promote apoptosis (using Annexin V-FITC conjugated and sub-G1 phase techniques).
