SOX9 [sex-determining region Y (SRY)-box 9 protein], a high mobility group box transcription factor, plays critical roles during embryogenesis and its activity is required for development, differentiation, and lineage commitment in various tissues including the intestinal epithelium. Here, we present functional and clinical data of a broadly important role(More)
Several microRNAs (miRNAs) are known to be deregulated in colon cancer, but the mechanisms behind their potential involvement on proliferation and tumor cell survival are unclear. The present study aimed to identify miRNAs with functional implications for development of colon cancer. The cell proliferation and apoptosis were examined following perturbations(More)
Single-stranded (ss) and double-stranded (ds) small interfering RNAs (siRNAs) containing immunostimulatory RNA motifs can activate innate immunity through Toll-like receptor 7/8 (TLR7/8), leading to the production of proinflammatory cytokines and type I interferon. More recently, we have noted that 2'-uridine modified ss or ds siRNAs not only evade immune(More)
Ribonucleic nucleic acid recognition by Toll-like receptors (TLRs) induces innate immune responses. However, no comprehensive analysis of gene expression in human blood cells in response to unmodified and 2'-modified immunostimulatory RNAs has been reported. Using oligonucleotide microarrays, we show that around 400 genes were significantly (P<0.001)(More)
Ubiquitination controls multiple cellular processes relevant to cancer pathogenesis. Using Gene Set Enrichment Analysis of an mRNA transcriptome dataset, we have identified genes encoding components of the ubiquitin system that are differentially expressed in colorectal cancers as compared to normal colonic mucosa. Among the significantly overexpressed(More)
Colorectal cancer (CRC) incidence increases with age, and early onset of the disease is an indication of genetic predisposition, estimated to cause up to 30% of all cases. To identify genes associated with early-onset CRC, we investigated gene expression levels within a series of young patients with CRCs who are not known to carry any hereditary syndromes(More)
MicroRNAs (miRNAs) represent a new class of small noncoding RNAs expressed in plants and animals. They are responsible for the regulation of up to 30% of human genes, thus underlying their influence on almost all cellular pathways. Recent studies have shown miRNAs to be differentially expressed in cancers. Furthermore, several miRNAs are associated with(More)
Differentiation of monocytes into dendritic cells (DCs) is characterised by marked changes in gene expression. The role of microRNAs (miRNAs), a new class of small endogenous non-coding regulatory RNAs, in this process is still unclear. We identified miR-223, miR-16, miR-191, miR-24, let-7b, and miR-21 as differentially expressed between monocytes and(More)
MicroRNAs (miRNAs) are small, non-coding RNAs that mediate post-transcriptional gene silencing, fine tuning gene expression. In an initial screen, miRNAs were found to be globally down-regulated in prostate cancer (PCa) cell lines and primary tumours. Exposure of PCa cell lines to a demethylating agent, 5-Aza-CdR resulted in an increase in the expression(More)
DNA supercoiling is a major regulator of transcription in all organisms. This process is regulated by type I and type II DNA topoisomerases that are targets for microbial antibiotics and/or anti-tumour drugs. Despite extensive studies in this field, no information is available on the response of Bacillus (B) species to eukaryotic DNA topoisomerase(More)
