Article
Full-text available
Our intestinal microbiota harbours a diverse bacterial community required for our health, sustenance and wellbeing. Intestinal colonization begins at birth and climaxes with the acquisition of two dominant groups of strict anaerobic bacteria belonging to the Firmicutes and Bacteroidetes phyla. Culture-independent, genomic approaches have transforme...
Article
Full-text available
The Human Pan-Microbe Communities (HPMC) database (http://www.hpmcd.org/) provides a manually curated, searchable, metagenomic resource to facilitate investigation of human gastrointestinal microbiota. Over the past decade, the application of metagenome sequencing to elucidate the microbial composition and functional capacity present in the human m...

Breast cancer metastasis is a key determinant of long-term patient survival. By comparing the transcriptomes of primary and metastatic tumor cells in a mouse model of spontaneous bone metastasis, we found that a substantial number of genes suppressed in bone metastases are targets of the interferon regulatory factor Irf7. Restoration of Irf7 in tum...

Full-text available
Interferome v2.0 (http://interferome.its.monash.edu.au/interferome/) is an update of an earlier version of the Interferome DB published in the 2009 NAR database edition. Vastly improved computational infrastructure now enables more complex and faster queries, and supports more data sets from types I, II and III interferon (IFN)-treated cells, mice...
Article
Full-text available
Understanding gut microbiome functions requires cultivated bacteria for experimental validation and reference bacterial genome sequences to interpret metagenome datasets and guide functional analyses. We present the Human Gastrointestinal Bacteria Culture Collection (HBC), a comprehensive set of 737 whole-genome-sequenced bacterial isolates, repres...
Article
Full-text available
Campylobacter fetus is a venereal pathogen of cattle and sheep, and an opportunistic human pathogen. It is often assumed that C. fetus infection occurs in humans as a zoonosis through food chain transmission. Here we show that mammalian C. fetus consists of distinct evolutionary lineages, primarily associated with either human or bovine hosts. We u...
Article
Full-text available
Advances in high-throughput sequencing technologies and the development of sophisticated bioinformatics analysis methods, algorithms, and pipelines to handle the large amounts of data generated have driven the field of human microbiome research forward. This specialist knowledge has been crucial to thoroughly mine the human gut microbiota, particul...
Article
p>This month's Genome Watch highlights the variation in gut microbiota across different human communities and explores how this is associated with lifestyle and diet.</p
Article
This month's Genome Watch discusses the release of 1,003 bacterial and archaeal genomes, and describes how they could increase our understanding of the diversity of microbial biological functions and contribute to improved metagenomic analyses.
Article
Transmission of commensal intestinal bacteria between humans could promote health by establishing, maintaining and replenishing microbial diversity in the microbiota of an individual. Unlike pathogens, the routes of transmission for commensal bacteria remain unappreciated and poorly understood, despite the likely commonalities between both. Consequ...
Article
Full-text available
Type I interferons (IFNs) are an important family of cytokines that regulate innate and adaptive immune responses to pathogens, in cancer and inflammatory diseases. While the regulation and role of protein-coding genes involved in these responses are well characterized, the role of non-coding microRNAs in the IFN responses is less developed. We rev...
Article
Full-text available
Anti-microRNA (miRNA) oligonucleotides (AMOs) with 2'-O-Methyl (2'OMe) residues are commonly used to study miRNA function and can achieve high potency, with low cytotoxicity. Not withstanding this, we demonstrate the sequence-dependent capacity of 2'OMe AMOs to inhibit Toll-like receptor (TLR) 7 and 8 sensing of immunostimulatory RNA, independent o...
Article
Full-text available
A single high dose of interferon-β (IFNβ) activates powerful cellular responses, in which many anti-viral, pro-apoptotic, and anti-proliferative proteins are highly expressed. Since some of these proteins are deleterious, cells downregulate this initial response rapidly. However, the expression of many anti-viral proteins that do no harm is sustain...
Article
Full-text available
Type I interferons are important in regulating immune responses to pathogens and tumors. All interferons are considered to signal via the heterodimeric IFNAR1-IFNAR2 complex, yet some subtypes such as interferon-β (IFN-β) can exhibit distinct functional properties, although the molecular basis of this is unclear. Here we demonstrate IFN-β can uniqu...
Article
Full-text available
Helicobacter pylori causes chronic gastritis and avoids elimination by the immune system of the infected host. The commensal bacterium Lactobacillus acidophilus has been suggested to exert beneficial effects as a supplement during H. pylori eradication therapy. In the present study, we applied whole-genome microarray analysis to compare the immune...
Article
Full-text available
Next-generation sequencing is rapidly becoming the approach of choice for transcriptional analysis experiments. Substantial advances have been achieved in computational approaches to support these technologies. These approaches typically rely on existing transcript annotations, introducing a bias towards known genes, require specific experimental d...
Article
Full-text available
The interferon (IFN) family and the type-I IFNs specifically have an important and well-characterized role in antiviral defence, immune modulation and cell-cycle control and are regularly applied in the clinical context. Advances in high-content technologies have facilitated an enhanced understanding of the global IFN response capable of being indu...
Article
Full-text available
The Toll-like receptors (TLRs) are innate sensors that recognize both microbial and endogenous ligands, initiating the host defense response. TLRs initiate the potent proinflammatory response to infection, are the target for adjuvants, and are essential for the establishment and maturation of adaptive immunity. As such they have been the interest o...
Article
The interferons (IFNs) are a pleiotropic family of cytokines that perform fundamental functions in protecting host organisms from disease and in maintaining homeostasis. Like other multifunctional cytokines, excessive or inappropriate activity can cause toxicity and even death. Therefore, host organisms have evolved specific and highly regulated me...
Article
Full-text available
INTERFEROME is an open access database of types I, II and III Interferon regulated genes (http://www.interferome.org) collected from analysing expression data sets of cells treated with IFNs. This database of interferon regulated genes integrates information from high-throughput experiments with annotation, ontology, orthologue sequences from 37 sp...
