Expression data of exosomal miRNAs extracted from serum

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin Lymphoma with complex clinical symptoms. Currently, the diagnosis of DLBCL depends largely on pathologic analysis of biopsy tissue, which is an invasive procedure and often poses some risk to patients. Exosomal miRNAs have emerged as promising noninvasive biomarkers for detecting tumor or monitoring disease progress. We aim to investigate the potential of circulating exosomal miRNAs to assist with diagnosis of DLBCL.In the present research, we used the miRCURY LNA™ microRNA Array to investgate the profiles of differentially expressed miRNAs in the exosomes of peripheral blood serum. As a result, circulating exosomal miRNA profiling yielded a total of 332 differentially expressed miRNAs (157 with up-expression and 175 with down-expression) between the DLBCL patients and healthy controls. Serum samples of 10 DLBCL patients and 5 healthy controls were collected for exosomal miRNAs extraction and hybridization on 7th miRCURY LNA™ microRNA Array
