Conclusion
Hsa-miR-128a boosted the effect of pembrolizumab on laryngeal cancer cells, perhaps via the p53 pathway. Therefore, hsa-miR-128a might be a novel target in laryngeal cancer treatment.
Methods
Hep2 and AMC-HN8 cell lines were utilized to create stable cell lines that overexpressing hsa-miR-128a. Using the immunotherapy assay, the contribution of hsa-miR-128a to pembrolizumab sensitivity was evaluated. By performing the dual luciferase assay and quantitative real-time polymerase chain reaction, the possible mechanisms of hsa-miR-128a were identified.
Results
Hsa-miR-128a was overexpressed in laryngeal cancer cell lines successfully. The immunotherapy assay revealed that upregulating hsa-miR-128a augmented the effect of pembrolizumab. Moreover, hsa-miR-128a targeted BMI-1 and might played a role in the p53 pathway.
