AKT1 and nasopharyngeal carcinoma: To explore the mechanism of heterozygous p53-R280T-promoting NPC cell oncogenicity, we compared the mRNA expression profiles in the heterozygous p53-R280T knockout and control CNE2 cells by mRNA sequencing, and found PI3K-Akt signaling pathway involved in the tumor-promotion effect of heterozygous p53-R280T mutation.
