CDKN2A and nasopharyngeal carcinoma: Then, we introduced NPC‐related genetic alterations into CAG‐Cas9‐EGFP; Trp53‐/‐ nasopharyngeal organoids by mCherry‐linked sgRNA targeting Cdkn2a and overexpressing Myc together with luciferase, which could help to monitor these cells in vivo (Figure S2C and D, Supporting Information).
