A dietary intervention study in which male mice are given one of 10 diets with different proportions of protein, fat and carbohydrates, and then mated to produce offspring. Following which, we examine the effect of these different diets on the overall health and behaviour of both the males and their offspring. We are especially looking for an epigenetic patterns.
TEs (Transposable Elements), escape epigenome reprogramming and therefore represent potential hotspots of heritable information that can be passed on to future generations. The Latin suffix –theca (from Ancient Greek thēkē) is used for any kind of collection. The goal of the GeckoTEk project is to generate a near-complete human sperm (epi)genome of high-quality, using third-generation sequencing technologies with a particular focus on difficult genomic regions and repetitive sequences.
Three-dimensional conformation of genomes02
Three-dimensional conformation of genomes
An ex vivo characterisation of tissue specific epigenetic remodelling in offspring sired from nutritionally challenged fathers. We utilise approaches such as HI-C and ATAC-seq to develop a picture of genetic architecture, and integrate chromatin confirmation and transcriptomic data to determine how epigenetic regulatory elements reshape the genome.
A nutritional intervention study with mini-pigs.03
A nutritional intervention study with mini-pigs.
EpiPIG is a research study in which we are giving mini-pigs either a ‘Western’ high fat/high sugar diet or a normal pig diet to better understand what epigenetic impact this has on their sperm.
Food intake and Epigenetic Alteration in the Spermatozoa of Singletons and Twins – Singletons Study.05
Food intake and Epigenetic Alteration in the Spermatozoa of Singletons and Twins – Singletons Study.
A human dietary intervention study where participants receive different commonly consumed diet patterns and we are examining the impact it has on epigenetic markers in the sperm. This part of the study is with individual people, singletons.
Food intake and Epigenetic Alteration in the Spermatozoa of Singletons and Twins – Twins Study.06
Food intake and Epigenetic Alteration in the Spermatozoa of Singletons and Twins – Twins Study.
A human dietary intervention study where participants receive different commonly consumed diet patterns and we are examining the impact it has on epigenetic markers in the sperm. This branch of the study has twin male participants.
A nutritional intervention study with guinea pigs09
A nutritional intervention study with guinea pigs
A dietary intervention study with guinea pigs fed high or low –fat diets with or without additional Vitamin C to identify through which mechanisms nutritional factors influence epigenetic inheritance of obesity and metabolic disease.
Sperm Epigenomics Across Species10
Sperm Epigenomics Across Species
A partnership with Taronga Zoo and the Copenhagen Zoo to assess sperm epigenetic signatures across a wide range of species. The study aims to build a reference map of sperm epigenome modifications among animal species to understand similarities and differences in what environmental information is transmitted in sperm.

Sperm Epigenetics and Exercise11
Sperm Epigenetics and Exercise
Endurance training remodels sperm-borne small RNA expression and methylation at neurological gene hotspots.
We exposed young men to a 6-week endurance training exercise regime, and measured the epigenetic signature of their sperm before and after the intervention. This study highlighted exercise-induced remodelling of genes involved in the brain.
Obesity and Bariatric Surgery Drive Epigenetic Variation of Spermatozoa in Humans12
Obesity and Bariatric Surgery Drive Epigenetic Variation of Spermatozoa in Humans
The epigenetic signature of both lean and obese men, and men before after weight loss was examined, highlighting both rapid and long-term remodelling of the sperm epigenome at gene regions involved in appetite regulation.
