The majority of immune components such as Toll-like receptor (TLR)-2, interleukin (IL)-17, neutrophils, and IL-10 play pivotal roles in immunity to Candida albicans (C. albicans) through identifying and launching inflammatory and regulatory responses. Chemotherapy is one of the most potent risk factors for systemic candidiasis through inducing immunosuppression (mostly cyclophosphamide induced immunosuppression) and there is a sensible lack of study around the immunity to C. albicans in such a situation. In this study, following the establishment of infection and immunosuppression in Balb/c mice model, the mRNA/protein levels of TLR-2, IL-10, IL-17, and Myeloperoxidase (MPO) in serum/kidney were measured using Real-time PCR and ELISA respectively...

This study aimed to explore the role of long non-coding RNA NEAT1 in sepsis-induced acute kidney injury (AKI). The expression levels of NEAT1 in sepsis-induced AKI patients were detected. The rat mesangial cells (RMCs) were treated with lipopolysaccharide (LPS) to induce cell injury. Then, the effects of NEAT1 suppression on the cell viability, apoptosis, cytokines expression, and oxidative stress in the LPS-stimulated RMCs were tested. The regulatory miRNA of NEAT1, as well as the target genes of this miRNA, were investigated...

Caprine parainfluenza virus type 3 (CPIV3) is a newly emerging pathogenic respiratory agent infecting both young and adult goats, and it was identified in eastern China in 2013. Cellular microRNAs (miRNAs) have been reported to be important modulators of the intricate virus-host interactions. In order to elucidate the role of miRNAs in madin-darby bovine kidney (MDBK) cells during CPIV3 infection. In this study, we performed high-throughput sequencing technology to analyze small RNA libraries in CPIV3-infected and mock-infected MDBK cells...

We conducted comprehensive integrative molecular analyses of the complete set of tumors in The Cancer Genome Atlas (TCGA), consisting of approximately 10,000 specimens and representing 33 types of cancer. We performed molecular clustering using data on chromosome-arm-level aneuploidy, DNA hypermethylation, mRNA, and miRNA expression levels and reverse-phase protein arrays, of which all, except for aneuploidy, revealed clustering primarily organized by histology, tissue type, or anatomic origin. The influence of cell type was evident in DNA-methylation-based clustering, even after excluding sites with known preexisting tissue-type-specific methylation...

MicroRNA (miRNA) in urine has been considered as a potential biomarker for early-stage diagnosis of multiple diseases like urinary system cancer, kidney injury and diabetes, owing to their many demonstrated advantages including long-term stability and noninvasiveness. However, the traditional enrichment and extraction processes of miRNAs from urine are cumbersome and tedious due to the low concentration and multiple carriers of miRNAs. Herein, we present a novel method to collect low concentrations of miRNAs from dilute solutions such as urine and cell culture medium...

Recently, accumulating evidences have indicated miRNAs play critical roles in the progression and development of various human complex diseases, which pointed out that identifying miRNA-disease association could enable us to understand diseases at miRNA level. Thus, revealing more and more potential miRNA-disease associations is a vital topic in biomedical domain. However, it will be extremely expensive and time-consuming if we examine all the possible miRNA-disease pairs. Therefore, more accurate and efficient methods are being highly requested to detect potential miRNA-disease associations...

The kallikrein-related peptidases (KLKs) constitute a family of 15 highly conserved serine proteases with trypsin- and chymotrypsin-like activities. Dysregulated expression and/or aberrant activation of KLKs have been linked to various pathophysiological processes, including cancer. Many KLKs have been identified as potential cancer biomarkers. microRNAs (miRNAs) are a class of small non-coding RNAs that regulate gene expression by pairing to the 3' untranslated region (UTR) of complimentary mRNA targets. miRNAs are dysregulated in many cancers, including prostate, kidney, and ovarian cancers...

Arsenic is a naturally occurring and highly potent metalloid known to elicit serious public health concerns. Today, approximately 200 million people around the globe are exposed to arsenic-contaminated drinking water at levels greater than the World Health Organization's recommended limit of 10 parts per billion. As a class I human carcinogen, arsenic exposure is known to elicit various cancers, including lung, skin, liver, and kidney. Current evidence suggests that arsenic is capable of inducing both genotoxic and cytotoxic injury, as well as activating epigenetic pathways to induce carcinogenesis...

Microvascular dysfunction leads to multi-organ failure and mortality in sepsis. Our previous studies demonstrated that administration of exogenous endothelial progenitor cells (EPCs) confers protection in sepsis as evidenced by reduced vascular leakage, improved organ function, and increased survival. We hypothesize that EPCs protect the microvasculature through the exosomes-mediated transfer of microRNAs (miRNAs). Mice were rendered septic by cecal ligation and puncture (CLP), and EPC exosomes were administered intravenously at 4 hr after CLP...

Non-coding RNAs (ncRNAs) are involved in the regulation of cell metabolism and neoplastic transformation. Recent studies have tried to clarify the significance of these information carriers in the genesis and progression of various cancers and their use as biomarkers for the disease; possible targets for the inhibition of growth and invasion by the neoplastic cells have been suggested. The significance of ncRNAs in lung cancer, bladder cancer, kidney cancer, and melanoma has been amply investigated with important results...

BACKGROUND: The treatment of muscle wasting is accompanied by benefits in other organs, possibly resulting from muscle-organ crosstalk. However, how the muscle communicates with these organs is less understood. Two microRNAs (miRs), miR-23a and miR-27a, are located together in a gene cluster and regulate proteins that are involved in the atrophy process. MiR-23a/27a has been shown to reduce muscle wasting and act as an anti-fibrotic agent. We hypothesized that intramuscular injection of miR-23a/27a would counteract both muscle wasting and renal fibrosis lesions in a streptozotocin-induced diabetic model...

INTRODUCTION: Currently, there is no accurate diagnostic molecular biomarker for renal cell carcinoma (RCC). The aim of this study was to assess the expression of microRNA-15a (miR-15a) in urine of patients with RCC and to evaluate its potential as a diagnostic molecular biomarker. MATERIALS AND METHODS: In total, 67 patients with solid renal tumors were enrolled: clear-cell RCC (ccRCC, n = 22), papillary RCC (pRCC, n = 16), chromophobe RCC (chRCC, n = 14), oncocytoma (n = 8), papillary adenoma (n = 2) and angiomyolipoma (n = 5)...

Mutant isocitrate dehydrogenase (IDH) 1/2 converts α-ketoglutarate (α-KG) to D-2 hydroxyglutarate (D-2-HG), a putative oncometabolite that can inhibit α-KG dependent enzymes, including ten-eleven translocation methylcytosine dioxygenase (TET) DNA demethylases. We recently established that miRNAs are components of the IDH1 mutant-associated glioma CpG island methylator phenotype (G-CIMP), and specifically identified MIR148A as a tumor-suppressive miRNA within G-CIMP. However, the precise mechanism by which mutant IDH induces hypermethylation of MIR148A and other G-CIMP promoters remains to be elucidated...

Cadmium (Cd) is a nephrotoxic environmental pollutant that causes a generalized dysfunction of the proximal tubule characterized by polyuria and proteinuria. Even though the effects of Cd on the kidney have been well-characterized, the molecular mechanisms underlying these effects have not been fully elucidated. MicroRNAs (miRNAs) are small non-coding RNAs that regulate cellular and physiologic function by modulating gene expression at the post-transcriptional level. The goal of the present study was to determine if Cd affects renal cortex miRNA expression in a well-established animal model of Cd-induced kidney injury...

BACKGROUND: BK polyomavirus (BKPyV) infection is a common asymptomatic viral infection in the general population. Severe complications are seen in immunocompromised individuals, such as polyomavirus-associated nephropathy (PyVAN) in renal transplant recipients. Information on BKPyV microRNA expressions is scarce, although polyomavirus-encoded microRNAs have been shown to control viral replication and assist in immune evasion. Whereas the pathogenic role of rearrangements in JC polyomavirus has been well established, little is known about BKPyV rearrangements in PyVAN...

The repertoire of miRNAs has considerably expanded during metazoan evolution, and duplication is an important mechanism for generating new functional miRNAs. However, relatively little is known about the functional divergence between paralogous miRNAs and the possible co-evolution between duplicated miRNAs and the genomic contexts. By systematically examining small RNA expression profiles across various human tissues and interrogating the publicly available miRNA:mRNA pairing chimeras, we found that changes in expression patterns and targeting preferences are widespread for duplicated miRNAs in vertebrates...
