Mechanistic study of PD-L1 regulation of metastatic proliferation in non-small cell lung cancer through modulation of IRE1α/XBP-1 signaling pathway in tumor-associated macrophages.
Objective: To explore the related research of PD-L1 in IRE1α/XBP-1 signaling pathway on non-small cell lung cancer.
Methods: The tumor model of mice was established and divided into four groups; after successful modeling, the tumor tissue of mice was removed for subsequent experiments; the bought THP-1 cells were grouped into four different groups, a control group, nivolumab intervention group, IRE1α inhibition group, and nivolumab intervention + IRE1α inhibition group; after co-culture of the four groups of THP-1 cells with A549, THP-1 cell protein levels in the four groups were analyzed using Western blot; A549 cell migration, invasion and proliferation were assessed using the scratch assay, Transwell method, monoclonal experiment and CCK-8 method.
Results: In vivo studies indicated that the stimulation of nivolumab could strongly check the progress of NSCLC (non-small cell lung); two groups treated with 4 μ8c showed obvious effects on check point of NSCLC; In vitro experiments including Western-blot experiment, Scratch experiment, Transwell method, Monoclonal experiment and CCK-8 experiment suggest that nivolumab could inhibit migration, invasion and proliferation of NSCLC tumor cells and it.
Conclusion: PD-L1 is capable of controlling metastatic and proliferative potential of NSCLC by the way of the modification of IRE1α/XBP-1 signaling in tumor-associated macrophages.
