Circulating microRNAs (miRNAs) are considered as reliable candidates for biomarker discovery. RNA-Sequencing has become the most suitable technique to accurately quantify the miRNAome. However, RNA-Sequencing relies on several technical passages before reaching the final-end. HTG EdgeSeq technology, thanks to the abrogation of RNA extraction step, allows productivity enhancement by reducing the number of hands-on steps, the time for sample preparation and, therefore, the costs. We found a strong correlation between qPCR and dPCR with HTG (Pearson's coefficient of 0.93 and 0.94, respectively). In conclusion, we showed that HTG EdgeSeq, performed on human plasma specimens without RNA extraction, is reliable, allows the simultaneous screening of more than 2,000 miRNAs, and thus, it could be applied to biomarker discovery in large cohorts.

Background: At present, existing risk scores together with traditional biomarkers such as troponin and brain natriuretic peptide (BNP) are still unable to accurately predict cancer therapy-related cardiac dysfunction (CTRCD). MicroRNAs (miRNAs) have emerged as promising biomarkers for improved identification of high-risk patients; however, limited studies have been performed in patients with HER2-positive breast cancer.
Objectives: To investigate the predictive potential of six serum-derived circulating miRNAs for CTRCD occurrence in patients with early-stage HER2-positive breast cancer receiving trastuzumab (TTZ).

Introduction: Ischemic heart disease (IHD) remains a major global health burden, highlighting the urgent need for early, non-invasive diagnostic biomarkers. MicroRNAs (miRNAs), small non-coding RNA molecules that regulate gene expression, have emerged as promising candidates due to their stability in circulation and involvement in cardiovascular processes. This systematic review aimed to evaluate the potential of specific miRNAs as early diagnostic biomarkers in IHD.

Objectives: Increasing detection of low-risk papillary thyroid carcinoma (PTC) is associated with overdiagnosis and overtreatment. N6-methyladenosine (mA)-mediated microRNA (miRNA) dysregulation plays a critical role in tumor metastasis and progression. However, the functional role of mA-miRNAs in PTC remains unclear.

Abnormal accumulation of TAR DNA-binding protein-43 (TDP-43) is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Small interfering RNAs (siRNAs) targeting TDP-43 offer potential therapeutic strategies for these diseases. However, efficient and safe delivery of siRNAs to the central nervous system (CNS) remains a critical challenge.

Background: Vitiligo is an acquired depigmentary disorder caused by the loss of functional melanocytes. Increasing evidence suggests that competing endogenous RNA (ceRNA) interactions participate in this process, yet their global architecture in vitiligo remains unclear.
Objective: To delineate a long non-coding RNA (lncRNA)-microRNA (miRNA)-mRNA ceRNA network associated with vitiligo and to identify blood-borne RNA markers with diagnostic potential.
