MetabolomicsA metabolomic strategy defines the regulation of lipid content and global metabolism by Δ9 desaturases in Caenorhabditis elegans
Caenorhabditis elegans provides a genetically tractable model organism to investigate the network of genes involved in fat metabolism and how regulation is perturbed to produce the complex phenotype of obesity. C. elegans possess the full range of desaturases, including the delta-9 desaturases expre...

TranscriptomicsFunction, targets and evolution of Caenorhabditis elegans piRNAs (small RNA-Seq)
piRNAs are required to maintain germline integrity and fertility but their mechanism of action is poorly understood. Here we demonstrate that C. elegans piRNAs silence transcripts in trans through imperfectly complementary sites. We find that target silencing is independent of Piwi endonuclease acti...

TranscriptomicsThe microRNA miR-124 controls gene expression in the sensory nervous system of Caenorhabditis elegans
We generated animals carrying a genomically integrated mir-124 promoter::gfp transgene and identified mir-124 promoter::GFP labelled cells as a subset of the C. elegans sensory neurons. We used fluorescence activated cell sorting (FACS) to isolate four distinct cell populations: mir-124 expressing (...

TranscriptomicspiRNAs can trigger a multigenerational epigenetic memory in the germline of C. elegans
Transgenerational effects likely have wide-ranging implications for human health, biological adaptation and evolution, however their mechanism and biology remain poorly understood. Here we demonstrate that a germline nuclear small RNA/chromatin pathway can maintain epi-allelic inheritance for many g...

TranscriptomicsNovel viruses naturally infecting Caenorhabditis nematodes trigger a small RNA response
C. elegans has served as a laboratory model organism due to its ease of manipulation and the availability of both forward and reverse genetics. In recent years, efforts to study host-pathogen interactions in C. elegans have increased. For example, analysis of infections by bacteria such as Pseudomon...

TranscriptomicsCharacterisation of microRNA expression in post-natal mouse mammary gland development [miRNA]
Background: The differential expression pattern of microRNAs (miRNAs) during mammary gland development might provide insights into their role in regulating the homeostasis of the breast epithelium. Our aim was to analyse these regulatory functions by deriving a comprehensive tissue-specific combined...

TranscriptomicsMicroRNA expression profiling of human breast cancer identifies new markers of tumour subtype
MicroRNAs (miRNAs), a class of short non-coding RNAs, often act post-transcriptionally to inhibit gene expression. We used a bead-based flow cytometric profiling method to obtain miRNA expression data for 93 primary human breast tumours, 21 cell lines and five normal breast samples. Of 309 human miR...
