Project description:The development of therapeutic resistance and metastatic dissemination takes place in 20-30% patients with nasopharyngeal carcinoma (NPC), resulting in poor survival. Hence, a better understanding of the underlying molecular mechanisms will help improve clinical outcome. We have identified a novel circRNA, circIPO7, as a promoter of metastasis and cisplatin chemoresistance in NPC cells. High-throughput RNA sequencing analysis was performed in the human nasopharyngeal carcinoma cell line S18 after transfection with control siRNA or circIPO7 siRNA.

Project description:Despite the docectaxel-cisplatin-5-fluorouracil (TPF) induction chemotherapy has greatly improved the patients' survival and became the standard of care for advanced nasopharyngeal carcinoma (NPC), some patients could not benefit from this therapy. The mechanism underlying the TPF chemoresistance remains unclear. Here, we identified ATMIN as a chemoresistance gene in response to TPF therapy in NPC patients. We found that USP10 deubiquitinates and stabilizes ATMIN protein. Knockdown of ATMIN inhibits the cell proliferation and facilitates the docetaxel-sensitivity of NPC cells in vitro and in vivo. Mechanistically, RNA-seq combined with ChIP-seq analysis suggests that ATMIN is associated with the cell death signaling. ATMIN transcriptionally activates LCK to facilitate cell proliferation and docetaxel-resistance. Our findings broaden the insight into the mechanism of chemoresistance in NPC and the USP10-ATMIN-LCK axis provides potential therapeutic targets for the management of NPC.

Hence, a better understanding of the underlying molecular mechanisms will help improve clinical outcome. We have identified a novel circRNA, circIPO7, as a promoter of metastasis and cisplatin chemoresistance in NPC cells. circIPO7 was found to bind to YBX1. Genome binding/occupancy profiling by high throughput sequencing were performed to explore the underlying molecular mechanisms.

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:MicroRNAs are biomarkers of prognosis and survival for many types of cancer. We evaluated whether microRNAs can predict the survival and efficacy of concurrent chemotherapy in nasopharyngeal carcinoma (NPC) patients. We retrospectively analyzed microRNA expression in 312 paraffin-embedded NPC specimens and 18 normal nasopharyngeal tissues using microarray. We found Forty-one microRNAs are differentially expressed between NPC and normal tissues, and a five-microRNA signature can predict survival independent of stage. NPC patients with the low-risk microRNA signature have a favorable response to concurrent chemotherapy. microRNA profiling of nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues 312 paraffin-embedded nasopharyngeal carcinoma tissues and 18 paraffin-embedded normal nasopharyngeal tissues
