Ischemic stroke, a major cause of death, is caused by occlusion of a blood vessel, resulting in a significant reduction in regional cerebral blood flow. MicroRNAs (miRNAs) are a family of short noncoding RNAs (18 to 22 nucleotides) and bind the 3' un-translated region (UTR) of their target genes to post-transcriptionally suppress gene expression. In this study, we report miR-143 is downregulated in rat neurons but high expressed in astrocytes cells. In vivo middle cerebral artery occlusion (MCAO) and ex vivo oxygen-glucose deprivation (OGD) results showed miR-143 was significantly induced by ischemia injury...

The kidding rate is one of the most important economic traits for goat production, but the genetic mechanism that is associated with ovulation rate is poorly understood. Recently, increasing evidence has suggested that microRNAs (miRNAs) influence ovarian biological processes. The present study provides the first comparison of the ovarian miRNAs of prolific Jintang black goats (JTGs) and non-prolific Tibetan goats (TBGs) during the follicular phase using RNA-Seq technology. We generated 11.19 million (M) and 11...

MicroRNAs (miRNAs), the small noncoding RNAs, regulate various biological processes such as adipogenesis. MicroRNA-143 (miR-143) promotes adipocyte differentiation, and is correlated with obesity in mice fed a high-fat diet. However, the transcriptional regulation of miR-143 is largely unknown. In this study, we identified that miR-143 is a target of peroxisome proliferator-activated receptor γ (PPARγ), a key transcription factor in adipogenesis. Four putative peroxisome proliferator response elements (PPREs) were identified in the miR-143 promoter region...

The human genome contains thousands of long intergenic noncoding RNAs (lincRNAs). However, the functional roles of these transcripts and the mechanisms responsible for their deregulation in colorectal cancer (CRC) remain elusive. A novel lincRNA termed upregulated in CRC (UCC) was found to be highly expressed in human CRC tissues and cell lines. UCC levels correlated with lymph node metastasis, Dukes' stage, and patient outcomes. In SW480 and SW620 cells, knockdown of UCC inhibited proliferation, invasion, and cell cycle progression and induced apoptosis in vitro...

MicroRNAs (miRNAs) regulate key biological processes, and their aberrant expression has been related to cancer development. Photodynamic therapy (PDT) has emerged as one of the most promising modalities for cancer treatment. However, the application of PDT has been limited to superficially localized human cancerous and precancerous lesions. To increase the usefulness of both PDT and miRNAs in cancer therapy, this study investigated whether apoptosis-related miRNA expression is influenced by PDT in oral cancer and whether miRNAs can enhance PDT efficacy...

Amyotrophic lateral sclerosis (ALS) is a fatal, neurodegenerative condition characterized by loss of motor neurones and progressive muscle wasting. There is no diagnostic test for ALS therefore robust biomarkers would not only be valuable for diagnosis, but also for the classification of disease subtypes, monitoring responses to drugs and tracking disease progression. As regulators of gene expression, microRNAs (miRNAs) are increasingly used for diagnostic and prognostic purposes in various disease states with increasing exploration in neurodegenerative disorders...

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...
