BACKGROUND/AIMS: Mesenchymal stromal cells (MSCs) participate in the tissue-specific repair of many different organs, especially the kidney. Their effects are primarily mediated by the paracrine release of factors including extracellular vesicles (EVs), which are composed of micro-vesicles and exosomes. The corresponding microRNAs (miRNAs) of EVs are considered important for their biological functions. METHODS: MSCs were cultured from the human umbilical cord, and EVs were isolated from the medium...

BACKGROUND: Aberrantly expressed microRNAs (miR) promote renal cell carcinoma (RCC) growth and metastasis and are potentially useful biomarkers for metastatic disease. However, a consensus clinically significant miRNA signature has not been identified. To identify a miRNA signature for predicting clinical outcome in RCC patients we used a four-pronged interconnected approach. METHODS: Differentially expressed miRs were identified and analyzed in 113 specimens (Normal kidney: 59; tumor: 54)...

MicroRNAs (miRNAs) are endogenous ∼22 nt noncoding RNAs that control the translation initiation and stability of target genes in a sequence-specific manner and, thus, play important regulatory roles in animals and plants. Homologs of Dom34, called Pelota or PELO, are broadly conserved in eukaryotes and archaea. Biochemical and genetic studies indicate that eukaryotic Dom34/Pelota plays an important role in cell division, differentiation of germline stem cells, and stem cell self-renewal by controlling the expression of specific genes at the translational level...

IgA nephropathy (IgAN) is the most common cause of primary glomerulonephritis worldwide. Up to 30% of cases develop the progressive form of the disease, eventually requiring renal replacement therapy. Diagnosis and risk stratification relies on an invasive kidney biopsy and management options are limited, with recurrence following renal transplantation being common. Thus the quest to understand the pathophysiology of IgAN has been one of great importance. MicroRNAs (miRs) are short nucleotides that suppress gene expression by hybridizing to the 3' untranslated region of messenger RNA (mRNAs), promoting mRNA degradation or disrupting translation...

TGFβ contributes to mesangial cell hypertrophy and matrix protein increase in various kidney diseases including diabetic nephropathy. Deptor is an mTOR-interacting protein and suppresses mTORC1 and mTORC2 activities. We have recently shown that TGFβ-induced inhibition of deptor increases the mTOR activity. The mechanism by which TGFβ regulates deptor expression is not known. Here we identify deptor as a target of the microRNA-181a. We show that in mesangial cells, TGFβ increases the expression of miR-181a to downregulate deptor...

The kidney is vulnerable to hypoxia-induced injury. One of the mechanisms underlying this phenomenon is cell apoptosis triggered by hypoxia-inducible factor-1-alpha (HIF-1α) activation. MicroRNA-210 (miR-210) is known to be induced by HIF-1α and can regulate various pathological processes, but its role in hypoxic kidney injury remains unclear. Here, in both kinds of rat systemic hypoxia and local kidney hypoxia models, we found miR-210 levels were upregulated significantly in injured kidney, especially in renal tubular cells...

Although Tacrolimus is an immunosuppressive drug widely used in renal transplantation, its chronic use paradoxically induces nephrotoxic effects, in particular renal fibrosis, which is responsible for chronic allograft dysfunction and represents a major prognostic factor of allograft survival. As molecular pathways and mechanisms involved in Tacrolimus-induced fibrogenic response are poorly elucidated, we assessed whether miRNAs are involved in the nephrotoxic effects mediated by Tacrolimus. Treatment of CD-1 mice with Tacrolimus (1 mg/kg/d for 28 days) resulted in kidney injury and was associated with alteration of a gene expression signature associated with cellular stress, fibrosis and inflammation...

Novel tissue injury biomarkers have recently been identified that outperform or add value to the conventional safety biomarkers. These novel biomarkers have enhanced sensitivity and/or specificity in monitoring drug-induced tissue injury in a variety of tissues, included liver, kidney, and skeletal muscle. Among these novel biomarkers, microRNAs (miRNAs) are one type in particular that have received much attention in recent years. These microRNAs are short, endogenous noncoding nucleic acids that are involved in modulation and regulation of mRNA transcripts...

MicroRNAs are a class of short, noncoding RNAs that are ubiquitous modulators of gene expression, with roles in development, homeostasis, and disease. Engineered microRNAs are now frequently used as regulatory modules in synthetic biology. Moreover, synthetic gene circuits equipped with engineered microRNA targets with perfect complementarity to endogenous microRNAs establish an interface with the endogenous milieu at the single-cell level. The function of engineered microRNAs and sensor systems is typically optimized through extensive trial-and-error...

Background: MicroRNAs (miRNAs) are a family of short noncoding RNAs that play important roles in posttranscriptional gene regulation. miRNAs inhibit target gene expression by blocking protein translation or by inducing mRNA degradation and therefore have the potential to modulate physiological and pathological processes. Summary: In the kidney, miRNAs play a role in the organogenesis and in the pathogenesis of several diseases, including renal carcinoma, diabetic nephropathy, cystogenesis, and glomerulopathies...

Human polyomavirus (HPyV) DNA genomes contain three regions denoted early viral gene region (EVGR) encoding the regulatory T-antigens and one microRNA, late viral gene region (LVGR) encoding the structural Vp capsid proteins, and non-coding control region (NCCR). The NCCR harbours the origin of viral genome replication and bi-directional promoter/enhancer functions governing EVGR- and LVGR-expression on opposite DNA strands. Despite principle similarities, HPyV-NCCRs differ in length, sequence, and architecture...

SRSF1, SRSF2 and hnRNP A1 are splicing factors that regulate the expression of oncogenes and tumor suppressors. SRSF1 and SRSF2 contribute to the carcinogenesis in the kidney. Despite their importance, the mechanisms regulating their expression in cancer are not entirely understood. Here, we investigated the microRNA-mediated regulation of SRSF1, SRSF2 and hnRNP A1 in renal cancer. The expression of microRNAs predicted to target SRSF1, SRSF2 and hnRNP A1 was disturbed in renal tumors compared with controls...

The present study investigated the role of microRNA (miR)‑146a in a diabetic nephropathy (DN) model, and its molecular mechanism. DN mice were given intraperitoneal injections of streptozotocin (55 mg/kg/day) for 5 consecutive days as an in vivo DN model. The HK‑2 human kidney cell line were exposed to 45% D‑glucose as an in vitro DN model. Firstly, it was demonstrated that miR‑146a expression was inhibited and NAPDH oxidase 4 (Nox4) was increased in DN mice. In HK‑2 cells, overexpression of miR‑146a inhibited Nox4 protein expression and decreased reactive oxygen species (ROS) generation, oxidative stress and inflammation, and suppressed vascular cell adhesion molecule‑1 (VCAM‑1) and intracellular adhesion molecule‑1 (ICAM‑1) protein expression...

Cell proliferation and apoptosis are typical hallmarks of autosomal dominant polycystic kidney disease (ADPKD) and cause the development of kidney cysts that lead to end-stage renal disease (ESRD). Many factors, impaired by polycystin complex loss of function, may promote these biological processes, including cAMP, mTOR and EGFR signalling pathways. In addition, microRNAs (miRs) may also regulate the ADPKD related signalling network and their dysregulation contributes to disease progression. However, the role of miRs in ADPKD pathogenesis has not been fully understood, but also the function of p53 is quite obscure, especially its regulatory contribution on cell proliferation and apoptosis...

Cold stress has a serious impact on the overwintering survival and yield of genetically improved farmed tilapia (GIFT, Oreochromis niloticus). Understanding the physiological and molecular regulation mechanisms of low-temperature adaptation is necessary to help breed new tolerant strains. The semi-lethal low temperature of juvenile GIFT at 96 h was determined as 9.4 °C. We constructed and sequenced two small RNA libraries from head kidney tissues, one for the control (CO) group and one for the 9.4 °C-stressed (LTS) group, and identified 1736 and 1481 known microRNAs (miRNAs), and 164 and 152 novel miRNAs in the CO and LTS libraries, respectively...

miRNAs (microRNAs), a small endogenous non-coding RNAs, play crucial roles in post-transcriptional regulator of genes expression in various biological processes. Cyprinid Herpesvirus-2 (CyHV-2) is a highly pathogenic member of the alloherpesviridae that causes acute mass mortalities in populations of Carassius auratus gibelio and Carassius auratus auratus. However, the molecular mechanisms underlying the pathogenicity of CyHV-2 have not been fully determined. Here, miRNA expression profiles were identified via high-throughput sequencing in the kidney of Carassius auratus gibelio infected or uninfected with CyHV-2...
