Abstract

V originále

Currently used molecular diagnostic tests for colorectal cancer (CRC) are underperforming and more sensitive, non-invasive biomarkers are needed. Long non-coding RNAs (lncRNA) and microRNA (miRNA) have shown potential as diagnostic biomarkers. Unfortunately, the identification of non-coding RNA circulating biomarkers in blood serum is significantly burdened by abundant RNA specimens from disrupted blood cells. Recently, small extracellular vesicles (sEVs) emerged as potential reservoirs of clinically relevant biomarkers, including lncRNAs and miRNAs. In theory, sEVs protect RNAs from degradation and might serve as a source of intact RNA for further analyses. However, there is a lack of evidence supporting the superior quality of RNA extracted from sEVs over RNA from whole blood serum. This study aimed to analyze the RNA content of blood serum and the sEVs derived from the blood serum of CRC patients and healthy controls using RNA sequencing. Moreover, small RNA sequencing was used to evaluate the difference in miRNA profiles of sEVs and corresponding blood sera of CRC patients and healthy controls.
