MicroRNAs (miRNAs) are small non-coding RNAs which participate in the post-transcriptional regulation of gene expression. They play important roles in cellular events such as growth and differentiation. Deregulation of miRNAs is frequently evident in human cancers where their aberrant expression is associated with uncontrolled proliferation, metastasis, impaired cell cycle and DNA damage response. The miRNAs are important in cancer as ∼50% of miRNA genes are located in cancer-associated regions such as fragile sites of genome...

Recently, several circulating miRNAs have been reported as promising, minimally invasive biomarkers for the diagnosis or prediction of the prognosis in various types of cancer. However, the utility of circulating miRNAs as predictive markers of the cancer response to neoadjuvant chemoradiotherapy (nCRT) for locally advanced rectal cancer is still unclear. To identify circulating serum miRNAs useful for predicting a pathological good response to nCRT, total 18 serum miRNAs of interest were analyzed by real-time polymerase chain reaction in 94 rectal cancer patients treated with nCRT and surgery...

Our previous studies have suggested a protective role for H. pylori infection in the prognosis of gastric cancer. Based on those findings, we hypothesized that H. pylori-positive and -negative gastric cancers may exhibit different growth patterns and pathobiological behaviors, indicating different mechanisms of cancer progression. By microarray analysis, we studied miRNAs expression profiles in 42 gastric cancer patients, comparing 21 H. pylori-positive and 21 H. pylori-negative groups. Luciferase reporter assay and western blot were used to examine the potential target genes of the interested miRNA...

Poor reproductive performance remains a major issue in the dairy industry, with low conception rates having a significant impact on milk production through extended calving intervals. A major limiting factor is the lack of reliable methods for early pregnancy diagnosis. Identification of animals within a herd that fail to conceive within 3 weeks after insemination would allow early re-insemination and shorten calving intervals. In a previous study, we found an increase in plasma miR-26a levels in Day 16-pregnant relative to non-pregnant heifers, however changes in miRNA levels that early during pregnancy were very small which likely prevented the identification of robust biomarkers...

MicroRNAs (miRNAs) are a class of short non-coding regulatory RNA molecules which play an important role in intracellular communication and cell signaling and which influence cellular processes such as proliferation, differentiation, and cellular death. Over the past two decades, the crucial role of microRNAs in controlling tissue homeostasis and disease in cardiovascular systems has become widely recognized. By controlling the expression levels of their targets, several miRNAs have been shown to modulate the function of endothelial cells (miR-221/222 and -126), vascular smooth muscle cells (miR-143/145) and macrophages (miR-33, -758, and -26), thereby regulating the development and progression of atherosclerosis...

In recent years, the number of complex but clinically effective biologicals such as multi-specific antibody formats and fusion proteins has increased dramatically. However, compared to classical monoclonal antibodies (mAbs), these rather artificially designed therapeutic proteins have never undergone millions of years of evolution and thus often turn out to be difficult-to-express using mammalian expression systems such as Chinese hamster ovary (CHO) cells. In order to provide access to these sophisticated but effective drugs, host cell engineering of CHO production cell lines represents a promising approach to overcome low production yields...

Long- lasting alterations in brain gene expression in alcohol addiction have been determined although no clear mechanism has yet been elucidated. There exist many factors regulating the mechanism of gene expression. We aimed in this study to detect miRNA (microRNA) and mRNA expression profile at the specific brain regions regarding ethanol exposure and withdrawal. Rats were exposed to liquid alcohol consumption for 21 days. Oligonucleotides microarrays and bioinformatics analyses were used to identify gene expression, miRNA expression and their functions in the Prefrontal cortex, Hippocampus and Corpus striatum of wistar rats...

The key pathological link between obesity and type 2 diabetes is insulin resistance but the molecular mechanisms are not entirely identified. MicroRNAs (miRNA) are dysregulated in obesity and may contribute to insulin resistance. Our objective was to detect and functionally investigate miRNAs linked to insulin sensitivity in human subcutaneous white adipose tissue (scWAT). Subjects were selected based on the insulin-stimulated lipogenesis response of subcutaneous adipocytes. Global miRNA profiling was performed in abdominal scWAT of 18 obese insulin resistance (OIR), 21 obese insulin sensitive (OIS) and nine lean women...

The medial entorhinal cortex (MEC) is important in spatial navigation and memory formation and its layers have distinct neuronal subtypes, connectivity, spatial properties, and disease susceptibility. As little is known about the molecular basis for the development of these laminar differences, we analyzed microRNA (miRNA) and messenger RNA (mRNA) expression differences between rat MEC layer II and layers III-VI during postnatal development. We identified layer and age-specific regulation of gene expression by miRNAs, which included processes related to neuron specialization and locomotor behavior...

Cervical cancer is a common female malignancy of global dimensions. MicroRNAs (miRNAs) play crucial roles in the development, differentiation, proliferation, and apoptosis of tumors. The non-coding RNA MALAT1 participates in various physiological processes that are important for proper functioning of the body. Here, we analyzed the expression of miRNA-143 and MALAT1 in HeLa cells to evaluate their roles in the occurrence and metastasis of cervical cancer. HeLa cells were divided into five groups depending on the treatment conditions, namely, transfected with miRNA-143, MALAT1, miRNA-143 inhibitor and the MALAT1 inhibitor, and the untreated control...

In the field of toxicology, the relationship between microRNAs (miRNAs) and microcystin-LR (MC-LR) toxicity in fish is still poorly understood. In the present study, we used quantitative real-time PCR (qPCR) to examine the expression of 7 miRNAs (let-7b, miR-21, miR-122, miR-27b, miR-148, miR-125a, and miR-143) that play regulatory roles in biological processes such as signal transduction, apoptosis, cell cycle, and fatty acid metabolism. Expression patterns were assessed in the liver, spleen, and kidney of silver carp following 8, 24, and 48 h of exposure to MC-LR via intraperitoneal injection (50 or 200 μg/kg of body weight)...

microRNAs (miRNAs) are a class of small RNAs that regulate gene expression. It has been demonstrated that aberrant miRNA expression is associated with cancer development and carcinogenesis. Altered miRNA expression has been suggested to occur in bladder cancer. In other cancer systems, studies have indicated that miR-143, as a tumor suppressor gene, plays essential roles in cancer progression. However, its role in bladder cancer has yet to be elucidated. In the present study, we observed that miR-143 expression was downregulated in human bladder cancer tissues and cells, and that its levels were negatively correlated with bladder cancer clinical stages...

The p53 tumour suppressor is a transcription factor that can increase the expression of mRNAs and microRNAs (miRNAs). HT29-tsp53 cells expressing a temperature sensitive variant of p53 have provided a useful model to rapidly and reversibly control p53 activity. In this model, the majority of p53-responsive mRNAs were upregulated rapidly but they were short-lived leading to rapid decay of the p53 response at the restrictive temperature. Here we used oligonucleotide microarrays and reverse transcriptase PCR to show that p53-induced miRNAs exhibited a distinct temporal pattern of expression...
