Similarly, MIR9-3HG can promote carcinogenesis of squamous cell carcinoma by affecting LIMK1 mRNA and protein levels via sponging miR-138-5p and recruiting TAF15, and it was also considered a predictive biomarker in HNSCC via multiple machine learning studies and q-RT PCR [39–42]. The gene discussed is TAF15; the disease is head and neck squamous cell carcinoma.
