IFN-γ-activated macrophages play an essential role in controlling intracellular pathogens; however, macrophages also serve as the cellular home for the intracellular pathogen Mycobacterium tuberculosis. Based on previous evidence that M. tuberculosis can modulate host microRNA (miRNA) expression, we examined the miRNA expression profile of M. tuberculosis-infected primary human macrophages. We ...

Relative quantification is the strategy of choice for processing RT-qPCR data in microRNAs (miRNAs) expression studies. Normalisation of relative quantification data is performed by using reference genes. In livestock species, such as pigs, the determination of reference miRNAs and the optimal number of them has not been widely studied. In this study, the stability of ten miRNAs (Ssc-let-7a, Ss...

Novel 2-substituted-6-[(4-substituted-1-piperidyl)methyl]-1H-benzimidazoles were designed and synthesized as Ebola virus inhibitors. The proposed structures of the new prepared benzimidazole-piperidine hybrids confirmed based on their spectral data CHN analyses. target compounds screened in vitro for anti-Ebola activity. Among tested molecules, 26a (EC50=0.93 ?M, SI = 10) 25a (EC50=0.64 20) pot...

MicroRNAs (miRNAs) are small RNAs that regulate target gene expression. Using microarray-based miRNA expression profiling, we compared the miRNA expression in granulocytes from four patients with acute myeloid leukemia and four healthy controls. Thirty-four miRNAs were found to be differentially expressed, including 20 miRNAs that were up-regulated and 14 miRNAs that were down-regulated. The ex...

Aberrant sialylation profiles on the cell surface have been recognized for their potential diagnostic value in identifying the regulation of tumor properties in several cancers, including hepatocellular carcinoma (HCC). Recently, increasing evidence has suggested that the deregulation of microRNA (miRNA) is a common feature in human cancers. In this study, we found obvious upregulation of sialy...

Serum exosomal microRNAs (miRNAs) have received considerable attention as potential biomarkers for tumor diagnosis. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) is commonly used to detect miRNA expression levels in various types of cancer. One prerequisite for valid RT‑qPCR data is the correct normalization of miRNAs to stably expressed endogenous reference genes (RGs)...

BACKGROUND Colorectal cancer is one of the most commonly diagnosed cancers and cancer- related death worldwide. Identification of new specific biomarkers could be helpful to detection of this malignancy. Altered plasma microRNA expression has been identified in many cancers, including colorectal cancer. OBJECTIVES The main objective of this study was to identify the circulating microRNAs with...

MicroRNAs fine-tune the regulation of Th1/Th17 lymphocyte subsets in multiple sclerosis. We investigated the expression of miRNAs (previously associated with mycobacterial and viral infections) in MS patients and healthy donors (HD) following 6 months natalizumab therapy. In addition, Th1/Th17 cytokines and the presence of anti-EBNA1/VCA IgG in MS patients with different pattern of miRNA expres...

Introduction Neuroblastoma (NB) is an often fatal pediatric cancer that arises from the precursor cells of the sympathetic nervous system. 13-Cis retinoic acid is used to treat high-risk disease. A derivative, all-trans-retinoic acid (ATRA) causes genome-wide demethylation in NB cells by up-regulating miRNAs such as miR-152 and miR-26a/b which are predicted to target the methyltransferases DNMT...
