HOXB8 promotes the proliferation ability of HNSCC cells. Notes: A: Expression level of HOXB8 in normal and HNSCC cell lines, *** = P < 0.001; B-C: Real-time quantitative PCR was used to detect the knockdown efficiency of HOXB8 in SCC-4 and CAL-27 cells, * = P < 0.05, *** = P < 0.001; D-E: CCK8 assay were performed in sh#ctl and sh#HOXB8 cells (SCC-4 and CAL-27 cell lines), ** = P < 0.01, *** = P < 0.001; F: Colony formation assay was performed in sh#ctl and sh#HOXB8 cells (SCC-4 and CAL-27 cell lines), *** = P < 0.001; G: EdU assay was performed in sh#ctl and sh#HOXB8 cells (SCC-4 and CAL-27 cell lines), *** = P < 0.001
