Increasing evidence suggests that oxidative stress plays an essential role during carcinogenesis. However, the underlying mechanism between oxidative stress and carcinogenesis remains unknown. Recently, microRNAs (miRNAs) are revealed to be involved in oxidative stress response and carcinogenesis. This study aims to identify miRNAs in hepatocellular carcinoma (HCC) cells which might involve in oxidative stress response. An integrated analysis of miRNA expression signature was performed by employing robust rank aggregation (RRA) method, and four miRNAs (miR-34a-5p, miR-1915-3p, miR-638, and miR-150-3p) were identified as the oxidative stress-responsive miRNAs...

BACKGROUND: The prevalence of chronic kidney disease (CKD) is increasing, leading to significant morbidity and mortality. Kidney biopsy remains the gold standard for diagnosing the underlying etiology of CKD, but the procedure carries complication risks. The aim of this study was to identify novel noninvasive biomarkers correlating with kidney function and histopathology in biopsy-proven CKD patients. METHODS: We profiled 2402 urinary microRNAs (miRNAs) to identify and confirm differentially expressed miRNAs associated with kidney function and histopathology in patients with diabetic nephropathy (n = 58) or lupus nephritis (n = 89), important etiologies of CKD, compared with healthy controls (n = 93 and 119, respectively)...

Mesenchymal stromal cells (MSC) are currently used in many cell based therapies. Prior to use in therapy, extensive expansion is required. We used microarray profiling to investigate expansion induced miRNA and mRNA expression changes of bone marrow MSCs (BM-MSCs) derived from old and young donors. The expression levels of 36 miRNAs were altered in cells derived from the old and respectively 39 miRNAs were altered in cells derived from young donors. Of these, only 12 were differentially expressed in both young and old donor BM-MSCs, and their predicted target mRNAs, were mainly linked to cell proliferation and senescence...

Follicular variants of papillary thyroid carcinoma include encapsulated (with or without capsular/vascular invasion) and infiltrative forms, which have different clinical behaviors. The encapsulated forms that lack capsular invasion have an indolent clinical behavior that is similar to benign lesions; therefore, they were recently reclassified as 'noninvasive follicular thyroid neoplasms with papillary-like nuclear features' (NIFTPs). Because NIFTPs have nuclear features of papillary carcinomas, distinguishing between NIFTPs and infiltrative follicular variant of papillary thyroid carcinoma is almost impossible with cytological examination...

The molecular mechanism responsible for Ewing's Sarcoma (ES) remains largely unknown. MicroRNAs (miRNAs), a class of small non-coding RNAs able to regulate gene expression, are deregulated in tumors and may serve as a tool for diagnosis and prediction. However, the status of miRNAs in ES has not yet been thoroughly investigated. This study compared global miRNAs expression in paraffin-embedded tumor tissue samples from 20 ES patients, affected by primary untreated tumors, with miRNAs expressed in normal human mesenchymal stromal cells (MSCs) by microarray analysis...

BACKGROUND: MicroRNAs (miRNAs) are noncoding RNA molecules that play important roles in the pathogenesis of various kidney diseases. We investigated whether patients with minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) have distinct circulating and urinary miRNA expression profiles that could lead to potential development of noninvasive biomarkers of the disease. MATERIALS AND METHODS: Exosome miRNAs were extracted from plasma and urine samples of patients with primary FSGS (n = 16) or MCD (n = 5) and healthy controls (n = 5)...

INTRODUCTION: Loss of the ability to concentrate (131)I is one of the important causes of radioiodine-refractory disease in papillary thyroid carcinoma (PTC). Recent advantages of serum microRNAs (miRNAs) open a new realm of possibilities for noninvasive diagnosis and prognosis of many cancers. The aim of the current study was to identify differential expression profiling of circulation miRNAs in PTC patients with non-(131)I and (131)I-avid lungs metastases. METHODS: The expressions of miRNAs were examined using miRNA microarray chip...

The antiapoptotic protein Bcl-2 is overexpressed in human cancers, and confers resistance to antitumor agents in cancer cells. Bcl-2 is negatively regulated by the tumor suppressor p53 in response to DNA damage during apoptotic cell death. However, this molecular mechanism remains unclear. The available evidence indicates that miR-1915 represses Bcl-2 expression at the post-transcriptional level in human colorectal carcinoma cells, which is correlated with drug resistance. Here, we show that p53 controls miR-1915 expression in response to DNA damage...

Adult renal progenitor cells (ARPCs) were recently identified in the cortex of the renal parenchyma and it was demonstrated that they were positive for PAX2, CD133, CD24 and exhibited multipotent differentiation ability. Recent studies on stem cells indicated that microRNAs (miRNAs), a class of noncoding small RNAs that participate in the regulation of gene expression, may play a key role in stem cell self-renewal and differentiation. Distinct sets of miRNAs are specifically expressed in pluripotent stem cells but not in adult tissues, suggesting a role for miRNAs in stem cell self-renewal...

BACKGROUND: Alterations in microRNA (miRNA) expression patterns in whole blood may be useful biomarkers of diverse cardiovascular disorders. We previously reported that miRNAs are significantly dysregulated in acute myocardial infarction (AMI) and applied machine-learning techniques to define miRNA subsets with high diagnostic power for AMI diagnosis. However, the kinetics of the time-dependent sensitivity of these novel miRNA biomarkers remained unknown. METHODS: To characterize temporal changes in the expressed human miRNAs (miRNome), we performed here the first whole-genome miRNA kinetic study in AMI patients...

Colorectal carcinoma is a frequent cause of cancer-related death in the world for men and women. microRNAs are endogenous small noncoding RNAs that regulate gene expression negatively at post-transcriptional level. Here, we investigated the possible role of microRNAs in the development of multidrug resistance (MDR) in colorectal carcinoma cells. We analyzed microRNA (miRNA) expression levels between multidrug resistant colorectal carcinoma cell line HCT116/L-OHP and its parent cell line HCT116 using a miRNA microarray...

Novel therapeutic approaches to eliminate cancer stem cells (CSCs) are being developed. This development is imperative as CSCs are resistant to drugs; they divide activated by ligands on the epithelium or on neighboring cancer cells. Specific commands for division originate from Notch-1 ligands. Notch-1 cleavage inhibitors can have opposite effects from the ones expected when the levels of Notch ligands are high on neighboring cancer cells. High levels of Jagged-1 are a common feature of ovarian tumors. Some gene pathways enhance, others repress transcription of Notch-1, while Notch-1 itself activates Myc and HIF-1α...
