Bioinformatics analysis identified high FMN2 expression in chemotherapy-resistant OC cell lines, validated experimentally. Stable FMN2 knockdown cell lines were generated via lentiviral transfection. Functional assays revealed that FMN2 overexpression conferred chemoresistance in vitro and in vivo and promoted M2 macrophage polarization via the CCL2/JAK2/STAT3 pathway. Co-culture with M2 macrophages enhanced cisplatin (DDP) resistance in OC cells, mediated by CXCL1 secretion, which activated the epithelial-mesenchymal transition (EMT) pathway. Clinically, FMN2 levels correlated with CCL2 and CD206 (M2 marker) in platinum-resistant patients, and high FMN2, CCL2, or CD206 expression predicted poorer overall and disease-free survival.

Initially, Gas was assessed for its influence on <i>C. elegans</i> lifespan, mobility, lipofuscin accumulation, and oxidative stress responses.

The new technology of CRISPR/Cas9 genome editing has significantly expedited the engineering of CAR-NK cells by enabling easy, multiplex, and precise changes to enhance their efficacy, persistence, and specificity to tumors. This review focuses on the incorporation of CRISPR technology into CAR-NK cell development. It examines uses of knockout of inhibitory checkpoint genes (<i>CISH</i>,<i> PD-1</i>, and <i>TGFBR2</i>), as well as knock-in of CAR into safe genomic locations and multiplex editing of CAR-NK cells to improve cytotoxicity against cancer while resisting suppression from the tumor microenvironment (TME). We further explore immuno-cytokine armoring strategies by knock-in of <i>IL-15</i> or <i>IL-12</i>, to ensure prolonged proliferation and survival of NK cells, and investigate CRISPR-mediated knockouts of immune inhibitors like <i>NKG2A</i> and <i>TIGIT</i>, to evade immune strategies used by the tumor to evade immune destruction. Furthermore, CRISPR-mediated upregulation of the homing receptor enhances NK cell tumor infiltration, addressing a major obstacle in treating solid tumors. It is significant to mention the progress in generating off-the-shelf products, which is a key step supporting the pursuit of allogeneic therapies. While substantial progress has been made, challenges remain related to optimizing CRISPR delivery, off-target effects, and enhancing in vivo persistence. Future directions of CAR-NK studies will likely capitalize on next-generation genome editing tools and synthetic biology for the development of tunable and logic-gated CAR-NK cells.
