[BMC Biol, 2018]

David Weinkove is an associate professor at Durham University, UK, studying host-microbe interactions in the model organism Caenorhabditis elegans. David has been focusing on the way microbes affect the physiology of their hosts, including the process of aging. In this interview, he discusses the questions shaping his research, how they evolved over the years, and his guiding principles for leading a lab.

[Neuronal Development, Synaptic Function, and Behavior Meeting, 2006]

Serial section electron microscopy is an essential source of image data for building 3D models of C. elegans anatomy with sufficient resolution to map neuronal development and synaptic connections. Despite continued advances in computing speed and capacity it is still difficult to store, visualize, and distribute large stacks of TEM images on PC and workstation computers. Achieving the proper mutual alignment and warping of image slices to simplify the segmentation and tracing of neuronal conections continues to be both computationally intensive and manually tedious. Developers at the Pittsburgh Supercomputing Center (PSC) have been working to extend the PSC Volume Browser (PSC-VB) to address these problems. PSC-VB is a networked client server system to interactively link users PC and Mac computers, running the PSC-VB graphical user interface, to high performance servers that provide large scale computing resources where the actual data storage and manipulation is done. The PSC-VB system, developed for use with the NLM Visible Human datasets and large MRI and CT time series studies of mouse cardiac function, was built to handle datasets to ~100 GBytes and is being extended to TByte scales. The system includes image processing toolkits, data upload services and the ability to import and export data volumes for use with other tools such as ImageJ. This poster describes the PSC-VB system and shows its use with original data from the MRC archives curated by David Hall and with a complete 3-fold embryo volume built from ~24 GBytes of TEM imagery captured by Richard Fetter in the Bargmann lab. A significant aim in both cases is to improve the speed and accuracy of segmentation and model construction by performing complete automated nonlinear slice alignment with minimal human intervention. We are working to extend the system to include additional data modalities and means for remote data sharing and collaborative multi-user work sessions.

Amrit FRG et al. (2017) J Vis Exp "Transcriptomic Analysis of C. elegans RNA Sequencing Data Through the Tuxedo Suite on the Galaxy Project."

Ghazi A, Amrit FRG

[J Vis Exp, 2017]

Next generation sequencing (NGS) technologies have revolutionized the nature of biological investigation. Of these, RNA Sequencing (RNA-Seq) has emerged as a powerful tool for gene-expression analysis and transcriptome mapping. However, handling RNA-Seq datasets requires sophisticated computational expertise and poses inherent challenges for biology researchers. This bottleneck has been mitigated by the open access Galaxy project that allows users without bioinformatics skills to analyze RNA-Seq data, and the Database for Annotation, Visualization, and Integrated Discovery (DAVID), a Gene Ontology (GO) term analysis suite that helps derive biological meaning from large data sets. However, for first-time users and bioinformatics' amateurs, self-learning and familiarization with these platforms can be time-consuming and daunting. We describe a straightforward workflow that will help C. elegans researchers to isolate worm RNA, conduct an RNA-Seq experiment and analyze the data using Galaxy and DAVID platforms. This protocol provides stepwise instructions for using the various Galaxy modules for accessing raw NGS data, quality-control checks, alignment, and differential gene expression analysis, guiding the user with parameters at every step to generate a gene list that can be screened for enrichment of gene classes or biological processes using DAVID. Overall, we anticipate that this article will provide information to C. elegans researchers undertaking RNA-Seq experiments for the first time as well as frequent users running a small number of samples.

As any homeowner knows, timely maintenance is vital for keeping a building functioning properly after construction is finished. The same is evidently true for the complex architecture of the nervous system - at least in the roundworm. On page 686, neuroscientists Oliver Hobert, Oscar Aurelio, and David Hall describe a new family of proteins that help keep the wiring of the worm's nervous system tangle free.

[Parasitol Today, 1996]

Historically, peptidergic substances (in the form of neurosecretions) were linked to moulting in nematodes. More recently, there has been a renewal of interest in nematode neurobiology, initially triggered by studies demonstrating the localization of peptide immunoreactivities to the nervous system. Here, David Brownlee, Ian Fairweather, Lindy Holden-Dye and Robert Walker will review progress on the isolation of nematode neuropeptides and efforts to unravel their physiological actions and inactivation mechanisms. Future avenues for research are suggested and the potential exploitation of peptidergic pathways in future therapeutic strategies
