In lung squamous cell carcinoma, circTP63 competitively binds to miR-873-3p to upregulate FOXM1, promoting the proliferation of lung squamous cell carcinoma [8]; circSCAP interacts with the SF3A3 protein to inhibit the malignant progression of non-small cell lung cancer [9]. This evidence concerns the gene SF3A3 and squamous cell lung carcinoma.
