A long read, and a tricky jigsaw puzzle - Genomics Aotearoa

Apr 05, 2019

Peter Dearden Sequencing is an essential part of creating a genome, be it human, stick insect, kākāpō or sheep (all genomes Genomics Aotearoa is currently working on). But what is sequencing, how does it work, and why does it take so long?  And why does it matter to us? Sequencing is a laboratory process where segments of DNA base pairs are put in order, so researchers know where genes are located on the chromosomes. Genomics Aotearoa is finding the best ways of new genomic technologies to assemble genomes of organisms important to NZ medicine, agriculture and conservation, and to make those into technology ‘pipelines’. That will streamline processes, and make the technology more readily available to other research projects. Current sequencing technology means the whole genome can’t be produced in one go. Researchers, therefore, cut DNA into pieces, then they … Read More

Why it’s important to have Māori-led capacity in genomics research - Genomics Aotearoa

Mar 06, 2019

Dr Phillip Wilcox Genomics research is an emerging frontier that will mean applications such as personalised medicine being developed for New Zealand-specific problems, and something that will see an increasing focus on the needs of Māori populations. However, Māori are significantly under-represented in genomic sciences. One successful way of building capability to improve understanding of genomics among Māori has been the Summer Internship of Native peoples in Genomics (SING) Aotearoa internship programme, an innovative initiative now co-sponsored by Genomics Aotearoa that we have been running since 2016. Phil Wilcox at SING Aotearoa 2019. This year, 20 SING interns spent a week in Palmerston North with some our best genomics researchers, the aim being for pākeke (Māori adults) and graduate-level Māori students to improve their understanding of the technologies, as well as the … Read More

A random bioinformatics career walk … and how Genomics Aotearoa is helping researchers be a little less scared of the “command line” - Genomics Aotearoa

Jan 30, 2019

Dr Alana Alexander A “random walk” is a mathsy term for a path strung together with a bunch of random steps (not unlike trying to walk my stubborn St. Bernard cross on a leash). Despite being a bioinformatician (which folks often think means “also a maths wiz”), my maths is (unfortunately) not great. Therefore, I mention random walks not because I’m about to drop a knowledge bomb about higher-dimensional Riemannian manifolds (thanks Wikipedia!), but because I think it is a great way to describe how I got into bioinformatics. Many researchers assume bioinformaticians have trained extensively to commune with processors, compilers, SLURM scripts, and core dumps. That’s definitely one way to become a bioinformatician, and probably a really smart one! Multiple universities in Aotearoa and internationally offer bioinformatics specialisations and/or degrees, and many of the other (brilliant) Genomics Aotearoa postdocs … Read More

How does epigenetics fit in? - Genomics Aotearoa

Dec 14, 2018

Greg Jones The study of epigenetics could well be a key tool in transforming valuable genomic information into useful health outcomes for New Zealanders. But what is epigenetics and why is it important? Epigenetics is the influence of genetic susceptibility combined with the complex interactions of each individual’s environment over their lifetime. An individual’s epigenome is a dynamic personalised profile of environmental stress exposures, influenced by things like diet, gut microbiota, toxin and drug exposure, psychological and physical stressors and levels of activity throughout life. The field of epigenetics could have an important role in precision medicine – an emerging approach for disease management that tailors treatment to the individual, based on their genes and environment. Measuring the epigenetic changes that occur in diseases, including cancer and heart disease, provides an understanding of the underlying mechanisms. This insight can then … Read More
