There is an error in the third sentence of the Identification of small RNAs within bovine serum via RNA-seq section of the Results. The correct sentence is: On average, 54% mapped to tRNA, ~10% to other non-miRNA databases while 13% of reads could not be reliably mapped at all (Fig 3A). There are errors in Table 1. The publisher apologizes for these errors. Please see the corrected Table 1 here.
In this study a microRNA (miRNA) signature was identified in a gemcitabine resistant pancreatic ductal adenocarcinoma (PDAC) cell line model (BxPC3-GZR) and this signature was further examined in advanced PDAC tumor specimens from The Cancer Genome Atlas (TCGA) database. BxPC3-GZR showed a mesenchymal phenotype, expressed high levels of CD44 and showed a highly significant deregulation of 17 mi...
Hepatocellular carcinoma (HCC) that is graded histologically as poorly differentiated has a high recurrence, metastasis and poor prognosis. We sought to determine the regulatory mechanisms of HCC tumorigenesis and to identify molecules closely related to poorly differentiated HCC. High-throughput sequencing was used to construct microRNA (miRNA) and mRNA expression profiles for poorly different...
Gastric cancer (GC) is the second most frequent cause of cancer-related deaths worldwide. MicroRNAs are single-stranded RNA molecules of 21-23 nucleotides that regulate target gene expression through specific base-pairing interactions between miRNA and untranslated regions of targeted mRNAs. In this study, we generated a multistep approach for the integrated analysis of miRNA and mRNA expressio...
Altered expression of microRNAs (miRNA) occurs commonly in human cancer, but the mechanisms are generally poorly understood. In this study, we examined the contribution of epigenetic mechanisms to miRNA dysregulation in colorectal cancer by carrying out high-resolution ChIP-seq. Specifically, we conducted genomewide profiling of trimethylated histone H3 lysine 4 (H3K4me3), trimethylated histone...
Understanding the transcriptional regulation of microRNAs (miRNAs) is extremely important for determining the specific roles they play in signaling cascades. However, precise identification of transcription factor binding sites (TFBSs) orchestrating the expressions of miRNAs remains a challenge. By combining accessible chromatin sequences of 12 cell types released by the ENCODE Project, we foun...
Rifampin causes drug interactions by altering hepatic drug metabolism. Because microRNAs (miRNAs) have been shown to regulate genes involved in drug metabolism, we determined the effect of rifampin on the expression of hepatic miRNAs. Primary human hepatocytes from seven subjects were treated with rifampin, and the expression of miRNA and cytochrome P450 (P450) mRNAs was measured by TaqMan assa...
