Our data demonstrate that ukrain improves quality of life in patients suffering from advanced pancreatic cancer and significantly prolongs survival time in these patients.
OBJECTIVE. Assessment of diagnostic significance of exosomal microRNAs analysis in colorectal cancer (CRC). MATERIALS AND METHODS. Plasma samples from 100 patients with colon tumors and 20 healthy donors. Exosomes were isolated by differential ultracentrif ugation the analysis was performed by dynamic light scattering (DLS), cryo-EM, flow cytometry. Quantitative analysis of exosomal microRNAs was performed by RT-PCR. To evaluate the results obtained, the Kraskel-Wallis statistical test and ROC analysis were used. RESULTS. It is shown that CRC causes characteristic changes in the concentration of a number of exosomal microRNAs. Analysis of «reciprocal miRNAs pairs» was proposed as algorithmfor personalized diagnostic of CRC. The optimal parameters of diagnostic values were obtained for miRNA pair«miR-223 / miR-181a» (sensitivity =0.93, specificity =0.88). CONCLUSION. The analysis of exosomal microRNAs presents a promising method for early diagnostics / screening of colorectal cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
