Project description:To uncover the oncogenic pathways of nasopharyngeal carcinoma, gene expression profiles of primary NPC cell strains and NPC-derived cell lines were conducted and analyzed in depth. Keywords: Oncogenesis Gene expression profiles of 9 primary NPC cell strains and 5 NPC-derived cell lines were analyzed. Forty μg total RNA from one NPC sample was needed for a dye-swap experiment. Total RNA from 32 normal nasopharyngeal epithelial cell strains was pooled to serve as a universal reference.
Project description:Heterozygous p53-R280T mutations frequently occur in many nasopharyngeal carcinoma cell lines and nasopharyngeal carcinoma patients. However, the role of this mutation in the progression of nasopharyngeal carcinoma remains unclear. In this study, we successfully generated the tp53 knockout nasopharyngeal carcinoma (NPC) cells by CRISPR/Cas9-mediated genome editing and found that knockout of heterozygous tp53-R280T inhibited the proliferation of NPC cells significantly in vivo and in vitro. Mechanistic analyses indicated that heterozygous p53-R280T can activate the PI3K/Akt Signaling pathway in NPC cells. In conclusion, our findings provide a mechanistic insight into the role of heterozygous p53-R280T in NPC progression.

Project description:Three nasopharyngeal carcinoma cell lines (CNE1, CNE2, and HONE1) expression patterns against an immortalized nasopharyngeal epithelial cell line NP69. This study was done to screen genes consensually overexpressed in NPC. NP69 was used as normal control. The microarray analyses were done in a same batch.
