Prostate cancer (PCa) is the most frequent male malignancy and the second most common cause of cancer-related death in Western countries. Current clinical and pathological methods are limited in the prediction of postoperative outcome. It is becoming increasingly evident that small non-coding RNA (ncRNA) species are associated with the development and(More)
Today, the majority of prostate tumors are detected at early stages with uncertain prognosis. Therefore, we set out to identify early predictive markers of prostate cancer with aggressive progression characteristics. We measured the expression of microRNAs (miRNA) using qRT-PCR in formalin fixed and paraffin embedded prostatic tissue samples from a Swedish(More)
Transcriptome analysis of Aspergillus niger transfer cultures grown on galacturonic acid media identified a highly correlating cluster of four strongly induced hypothetical genes linked with a subset set of genes encoding pectin degrading enzymes. Three of the encoded hypothetical proteins now designated GAAA to GAAC are directly involved in further(More)
The ecological niche occupied by a fungal species, its pathogenicity and its usefulness as a microbial cell factory to a large degree depends on its secretome. Protein secretion usually requires the presence of a N-terminal signal peptide (SP) and by scanning for this feature using available highly accurate SP-prediction tools, the fraction of potentially(More)
The fungus Aspergillus niger is an industrial producer of pectin-degrading enzymes. The recent solving of the genomic sequence of A. niger allowed an inventory of the entire genome of the fungus for potential carbohydrate-degrading enzymes. By applying bioinformatics tools, 12 new genes, putatively encoding family 28 glycoside hydrolases, were identified.(More)
CONTEXT Genomic regions without protein-coding potential give rise to millions of protein-noncoding RNA transcripts (noncoding RNA) that participate in virtually all cellular processes. Research over the last 10 yr has accumulated evidence that long noncoding RNAs (lncRNAs) are often altered in human urologic cancers. OBJECTIVE To review current progress(More)
Decreased zinc levels are a hallmark of prostate cancer tumors as zinc uniquely concentrates in healthy prostate tissue. Increased dietary zinc correlates with decreased risk of advanced prostate cancer and decreased mortality from prostate cancer. The mechanisms of prostatic zinc homeostasis are not known. Lower zinc levels in the tumor are correlated(More)
The saprobic fungus Aspergillus niger is an efficient producer of a suite of extracellular enzymes involved in carbohydrate modification and degradation. Genome mining has resulted in the prediction of at least 39 genes encoding enzymes involved in the depolymerisation of the backbone of pectin. Additional genes,encoding enzymatic activities required for(More)
Small nucleolar RNAs (snoRNAs) are dynamically regulated in different tissues and affected in disease. SnoRNAs are processed further to stable smaller RNAs. We sequenced the small RNA transcriptome of prostate cancer (PCa) at different PCa stages and generated a quantified catalogue of 3927 small non-coding RNAs (sncRNAs) detected in normal and malignant(More)
Over the recent years, Next Generation Sequencing (NGS) technologies targeting the microRNA transcriptome revealed the existence of many different RNA fragments derived from small RNA species other than microRNA. Although initially discarded as RNA turnover artifacts, accumulating evidence suggests that RNA fragments derived from small nucleolar RNA(More)
