nCounter® miRNA Expression Assay Kit

Here, we describe several methods that can be employed to identify miRNAs in cells undergoing OIS, including miRNA-sequencing, RT-qPCR-based detection and quantification of miRNAs and Nanostring miRNA analysis (nCounter miRNA Expression Assay). Moreover, we perform a meta-analysis of studies employing the above methodologies, pinpoint miRNAs with consistent expression changes across senescence models, and predict their target genes and the pathways in which they partake.

The prognostic significance of EVs is closely tied to the unique expression profiles of miR-19a-3p and miR-130b-3p. These findings underscore the potential of EV-associated miRNAs as valuable indicators for BC recurrence, opening new avenues for diagnosis and treatment exploration.

Furthermore, we found 26 miRNA target genes for four of the five identified miRNAs, mainly related to pathways in cancer, RNA Polymerase II Transcription, RhoA signaling pathway, and PI3K-Akt signaling pathway. Conclusions This study demonstrated that those miRNAs could be used as non-invasive biomarkers in LBC samples, once they were able to distinguish CIN 2 and CIN3 patients from healthy women and regulate important molecular pathways of onset carcinogenesis.
