Article Abstract
Colorectal cancer (CRC) is the fourth most commonly diagnosed cancer and one of the leading causes of cancer death worldwide. Despite diagnostic and therapeutic advances, CRC mortality remains high, especially in industrialized countries. Numerous studies have highlighted the pathogenetic role of altered microRNA (miRNA) expression among the various factors contributing to the development and progression of colorectal cancer (CRC). However, the data regarding specific miRNAs involved in CRC pathogenesis remain inconsistent, and no miRNAs have been recognized so far as reliable or effective biomarkers for the diagnosis of this tumor type. To identify novel miRNA biomarkers in CRC, this study validated the expression levels of a four-miRNA signature predicted to be involved in CRC by analyzing both tissue and liquid biopsy samples. Our experimental and bioinformatics results highlighted the diagnostic potential of hsa-miR-21-5p, hsa-miR-503-5p, and hsa-miR-375, as well as the potential prognostic value of hsa-miR-497-5p overexpression and hsa-miR-375-3p downregulation. Overall, the results obtained suggest the diagnostic and prognostic significance of this four-miRNA signature in CRC.

Malignant mesothelioma (MM) is an aggressive malignant tumor of mesothelial origin that develops mainly in the parietal pleura or peritoneum and is strongly associated with asbestos exposure. MicroRNAs (miRNAs) can serve as biomarkers for the in vitro diagnosis of tumors. To investigate the differential expression of miRNAs in MM patients and identify potential diagnostic biomarkers, we sequenced miRNAs in formalin-fixed paraffin-embedded (FFPE) tumor tissues from 85 malignant pleural mesothelioma patients (samples collected between 1998 and 2017), and compared them with adjacent normal tissues, and the expression of four miRNAs was validated using in situ hybridization.

Objective: This study aims to screen common immunological markers of lung tissues and blood for diagnosis of tuberculosis (TB).
Methods: Differentially expressed miRNAs (DEmRs) and mRNAs (DEGs) were obtained by whole-transcriptome sequencing profiles on 18F-FDG PET/CT high and low metabolic active regions in lung tissues of nine TB patients. Common miRNAs were screened by intersecting with DEmRs, four miRNA GEO datasets, and their target mRNAs were predicted through the miRTarbase and Tarbase databases.

Background: The prognostic value of necroptosis-related microRNAs (miRNAs), which are important in tumorigenesis and development, remains unclear. Therefore, we aimed to screen prognostic necroptosis-related miRNAs in esophageal cancer (EC).
Methods: Nine necroptosis-related miRNA expression profiles and associated clinical data of EC patients were obtained from The Cancer Genome Atlas (TCGA) database.

Background: There is a pressing need to identify early biomarkers of lung involvement in systemic sclerosis to start antifibrotic therapy as soon as possible. We aimed to identify extracellular vesicle-derived microRNAs (miRNAs) that are differentially expressed between systemic sclerosis patients with and without interstitial lung disease, and to explore their diagnostic value and functional properties.
Methods: Small extracellular vesicles derived from plasma were isolated from 91 well-characterised patients with systemic sclerosis with (n=45) and without (n=46) interstitial lung disease and 43 matched healthy subjects.
