Research overview

In the present study, we aimed to identify whether plasma exosomal miRNAs could be potential diagnostic markers of LNM in PTC. The two plasma exosomal miRNAs (miR-6774-3p and miR-6879-5p) and their combination could serve as new promising biomarkers for the diagnosis of LNM in PTC patients.

Key findings

In total, 197 miRNAs were found to be differentially expressed in the testing set.

001) in the PTC-N1 patients was significantly higher than that in the controls.

962) were higher than those of the total miRNAs directly isolated from plasma.

Moreover, the expression of exosomal miRNAs was stable after treatment with RNase A, prolonged incubation, or repeated freezing and thawing.

Study design

Profiles of plasma exosomal miRNAs were screened using miRNA microarrays.

Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed in the validation and diagnostic sets to select candidate exosomal miRNAs.

Finally, receiver operating characteristic (ROC) curves were generated to evaluate the efficiency of target exosomal miRNAs in distinguishing PTC-N1 patients from PTC-N0 patients.
