{Abstract}: Aim: This study aimed to explore using peripheral blood mononuclear cell (PBMC)-derived chimeric antigen receptor (CAR) NK cells targeting ROBO1 as a personalized medicine approach for ovarian cancer. Methods: A two-step strategy generated ROBO1-targeted CAR NK cells from PBMCs of ovarian cancer patients. Efficacy was evaluated using xCELLigence RTCA, CCK-8 and Live/Dead fluorescence assays. Results: ROBO1-NK cells exhibited higher efficiency in eradicating primary ovarian cancer cells and lysing ovarian tumor organoids compared with primary NK cells without ROBO1-CAR modification. Conclusion: These findings highlight the potential of developing ROBO1-targeted CAR-NK cells from patients' PBMCs as a personalized treatment option for ovarian cancer.<BR>Ovarian cancer represents a formidable clinical challenge necessitating the urgent exploration of novel therapeutic approaches. In this study, the focus was directed toward ROBO1, a molecule known to play a pivotal role in cancer angiogenesis and metastasis, while limited investigation in the context of ovarian cancer. Leveraging this knowledge, we sought to construct ROBO1-targeting chimeric antigen receptor natural killer (CAR-NK) cells utilizing peripheral blood mononuclear cells derived from the patients themselves. The overarching goal of this investigation was to harness the potential of immunotherapy using autologous resources to realize personalized treatment strategies for ovarian cancer in clinical settings.
