ANXA5 and ovarian cancer: Human ovarian cancer cells (A2780/SKOV3) were subjected to three treatment conditions: untreated controls, dual immune checkpoint inhibitors (ICIs: 4 μg/mL Nivolumab + 4 μg/mL Ipilimumab), or ICIs combined with CIK cells (5×104 cells/insert), with functional impacts evaluated through comprehensive assays including CCK-8 proliferation, transwell invasion, Annexin V-FITC/PI apoptosis detection, propidium iodide-based cell cycle analysis, and quantitative wound healing migration assessment.
