Microarray expression profiles in S18 and S26 human nasopharyngeal carcinoma cell lines

ABSTRACT: Metastasis accounts for the leading cause of treatment failure in nasopharyngeal carcinoma (NPC). However, the exact mechanisms underlying metastasis remain elusive. S18 and S26 are a pair of NPC cell lines with high and low metastasis abilities, respectively. To evaluate the expression profiles of mRNA in S18 and S26 cells will help to demonstrate genes that contribute the metastasis of NPC. We performed microarray sequencing to clarify the genes that differentially expressed in S18 and S26 cells.

The RNA sequencing analysis of nasopharyngeal carcinoma (NPC) cell line S18 upon circWDR37 knockdown

Project description:Circular RNAs have been demonstrated to play significant roles in multiple biological processes, such as immune responses and tumorigenesis, suggesting it might be potential therapeutic targets. However, the function and mechanisms of circRNAs in nasopharyngeal carcinoma (NPC) metastasis remain largely unknown. In this study, we identified circWDR37 as a metastasis related circRNA. To further explore the underlying mechanism of circWDR37 promoting NPC metastasis, we performed RNA sequencing analysis of NPC cell line S18 upon circWDR37 knockdown.

The RNA sequencing analysis of nasopharyngeal carcinoma (NPC) cell line S18 upon circIPO7 knockdown

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.

Circular RNAs in nasopharyngeal carcinoma cell lines with different metastasis potential

Project description:Increasing evidence has demonstrated a significant role for circular RNAs (circRNAs) in tumorigenesis. However, their functions in nasopharyngeal carcinoma (NPC) metastasis remain largely unknown. In this study, a model compared high and low metastatic NPC cell lines (S18 vs. S26) was constructed to determine the expression profile of circRNAs using the RNA sequencing analysis.

Long non-coding RNAs and mRNAs in nasopharyngeal carcinoma metastasis

Project description:Increasing evidence has demonstrated a significant role for long non-coding RNAs (lncRNAs) in tumorigenesis. However, their functions in nasopharyngeal carcinoma (NPC) metastasis remain largely unknown. In this study, a model compared high and low metastatic NPC cell lines (5-8F vs. 6-10B and S18 vs. S26)was constructed to determine the expression profile of lncRNAs using the microarray analysis, and we found 167 lncRNAs and 209 mRNAs were differentially expressed. Validationof 26 significantly dysregulated lncRNAs by qRT-PCR showed the expression patterns of 22 lncRNAs were in accordance with the microarray data. Furthermore, the expression level of ENST00000470135, which was the most upregulated lncRNA in high metastatic cell lines, was significantly higher in NPC cell lines and tissues with lymph node metastasis（LNM）and knocking down ENST00000470135 suppressed the migration, invasion and proliferation of NPC cells in vitro. In conclusion, our study revealed expression patterns of lncRNAs in NPC metastasis. The dysregulated lncRNAs may act as novel biomarkers and therapeutic targets for NPC.

microRNA profile of human nasopharyngeal tissues: nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues

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

Affymetrix SNP array data for nasopharyngeal carcinoma samples

Project description:Nasopharyngeal carcinoma (NPC) has extremely skewed ethnic and geographic distributions, is poorly understood at the genetic level and is in need of effective therapeutic approaches. We determined the genomic landscape of 52 NPC cases with SNP-array analysis. This approach identified multiple recurrent SCNVs, with the most frequent deletion peak spanning the CDKN2A gene on 9p21. Additional SCNVs involving established cancer genes including CCND1, AKT2, MYC and TP53 were observed. Notably, we identified that one component of the SWI/SNF complex, ARID1A, was frequently deleted in NPC. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from fresh frozen nasopharyngeal carcinoma biopsy tissues Copy number analysis of Affymetrix 250K SNP arrays was performed for 52 nasopharyngeal carcinoma samples. Please note that the sample characteristics 'primary tumor size, metastasis, and regional lymph node' represents T, M and N in WHO TNM staging of nasopharyngeal cancer (according to American Joint Committee on Cancer (AJCC)), respectively.
