WDR77 (p = 2.86 × 10−131), TP63 (p = 1.09 × 10−303), and MKI67 (p = 2.49 × 10−103) were significantly enriched in PRMT5High HNSCC cells, whereas CDKN1A (p = 4.07 × 10−10) was significantly enriched in PRMT5Low HNSCC cells (Figure 2D, left panel). This evidence concerns the gene MKI67 and head and neck squamous cell carcinoma.
