Abstract Objectives Coronavirus disease 2019 (COVID-19) is a kind of viral pneumonia which caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). MicroRNAs (miRNA) are small non-coding RNAs consisting 19–25 nucleotides and play role in post-transcriptional gene regulation. We have focused on serum expression levels microRNA novel concept host–virus interactions. MicroRNA profil...
•Nine miRNAs were highly expressed in red blood cells after P. falciparum infection•Members of the let-7 family downregulated infection•Hsa-miR-451a was most abundant secreted miRNA within RBCs•The identified target genes that play roles immune responses Plasmodium falciparum, a human malaria parasite, develops (RBCs), which represent approximately 70% all cells. Additionally, RBC-derived extra...
BACKGROUND AND AIM Ulcerative Colitis (UC) is a type of inflammatory bowel disease, considered as an important disease of gastrointestinal tract having a huge impact on the health of the patient. Prolonged inflammation of colon in UC patients increases the risk of developing colorectal cancer. MiRNA are reported as a connecting link between inflammation and cancer. Differential miRNA expression...
Objective(s): Autophagy-related 4B (ATG4B) plays an important role in the process of autophagy induction. However, the molecular events that govern the expression of ATG4B in this process are not well known. Materials and Methods: Human ATG4B 3'-UTR region (1377 nt) containing miR-34a/miR-34c-5p binding site was amplified by PCR. Luciferase assay was used to assess the activity of reporter gene...
Differential microRNA expression in aristolochic acid-induced upper urothelial tract cancers ex vivo
Aristolochic acid (AA) is a carcinogenic, mutagenic and nephrotoxic compound commonly isolated from members of the plant family of Aristolochiaceae (such as Aristolochia and Asarum) and used in Chinese herbal medicine. Use of AA and AA‑containing plants causes chronic kidney disease (CKD) and upper urinary tract carcinoma (UUC); however, the underlying mechanism remains to be defined. miRNAs re...
Abstract To develop intervention strategies it is necessary to understand the host response influenza A virus (IAV) infection. The primary barriers for invading respiratory pathogens are airway epithelial cells of tract and several antimicrobial peptides produced by these cells. peptide, β-defensin-1, has antiviral activity against both enveloped non-enveloped viruses. Significant downregulatio...
BACKGROUND This study aimed to identify more potential genes and miRNAs associated with the pathogenesis of intracranial aneurysms (IAs). MATERIAL AND METHODS The dataset of GSE36791 (accession number) was downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were screened for in the blood samples from patients with ruptured IAs and controls, followed by fu...
Mesenchymal stem cells (MSC) comprise a promising tool for cellular therapy. These cells are usually culture expanded prior to their application. However, a precise molecular definition of MSC and the sequel of long-term in vitro culture are yet unknown. In this study, we have addressed the impact of replicative senescence on human MSC preparations. Within 43 to 77 days of cultivation (7 to 12 ...
Recently, there is ample evidence suggesting the important role of microRNAs (miRNAs) in autoimmune diseases via modulating B cells function. Primary biliary cholangitis (PBC) is a progressive immune-mediated liver disease with unclear pathogenic mechanism. Whether the miRNA in peripheral B cells of PBC involve the mechanisms of pathology and progression is not known. The present study explores...
OBJECTIVE Micro-RNAs (miRNAs) play a crucial role in controlling intestinal epithelial barrier function partly by modulating the expression of tight junction (TJ) proteins. We have previously shown differential messenger RNA (mRNA) expression correlated with ultrastructural abnormalities of the epithelial barrier in patients with diarrhoea-predominant IBS (IBS-D). However, the participation of ...
