Aim:
To determine the miRNA expression profiles of neuroblastomas with different clinical and histological characteristics.
Methods:
In this study 24 samples from 17 patients, paraffin blocks were used. Their microRNA profiles were compared by five different analysis: analysis I: well-poorly differentiated, analysis II: before-after chemotherapy, analysis III: favorable-unfavorable histology, analysis IV: neuroblastoma-ganglioneuroma, analysis V: low-risk-middle-risk-high risk groups. Clinical data were compared with differentially expressed microRNAs.
Results:
It was found that 25 miRNAs between well-poorly differentiated tumors, eight miRNAs before and after of the chemotherapy, three miRNAs between favorable and unfavorable histology, four miRNAs between neuroblastoma and ganglioneuroma, seven miRNAs between low and middle risk, one miRNA between middle and high risk, 14 miRNAs between low and high risk were differently expressed (P < 0.01). These miRNA's targeted mostly the cancer pathway by the KEGG pathway analysis. The most marked difference was seen in miR-132 and miR-490, comparing the clinical data and all microRNAs. The most fold change was detected at miR-98-5p between the tissues of high- and low-risk patients.
Conclusion:
In this study, we represent microRNA expression profiles of neuroblastoma patients' tissue with different clinical, histological grade, differentiation, and treatment status, and which could be informative for new therapies targeting microRNAs.
