BACKGROUND Most tissues in the body rely on the presence of gap junctions in order to couple their component cells electrically and metabolically via intercellular transport of ions, metabolites and signalling agents. As a result, cells within tissue... Read More about Metabolic heterogeneity during preimplantation development: The missing link?.

Parallels between embryo and cancer cell metabolism (2013)
Journal Article

A key characteristic of cancer cells is the ability to switch from a predominantly oxidative metabolism to glycolysis and the production of lactate even when oxygen is plentiful. This metabolic switch, known as the Warburg effect, was first described... Read More about Parallels between embryo and cancer cell metabolism.

Creatine Kinase (CK) catalyses the “creatine shuttle,” the reversible conversion of creatine phosphate to creatine with the liberation of ATP. This article examines the potential role of the creatine shuttle in the provision of ATP during mouse preim...

Elevated plasma nonesterified fatty acid (NEFA) concentrations are associated with negative energy balance and metabolic disorders such as obesity and type II diabetes. Such increased plasma NEFA concentrations induce changes in the microenvironment...

There is evidence that expression and methylation of the imprinted paternally expressed gene 1/mesoderm-specific transcript homologue (PEG1/MEST) gene may be affected by assisted reproductive technologies (ARTs) and infertility. In this study, we sou... Read More about Variable imprinting of the MEST gene in human preimplantation embryos.

The ratio of male/female embryos may be modified by environmental factors such as maternal diet in vivo and the composition of embryo culture media in vitro. We have used amino acid profiling, a noninvasive marker of developmental potential to compar... Read More about Amino acid metabolism of bovine blastocysts: A biomarker of sex and viability.

Removal of red light minimizes methylene blue-stimulated DNA damage in oesophageal cells: implications for chromoendoscopy (2009)
Journal Article

DNA damage and metabolic activity in the preimplantation embryo (2008)
Journal Article

BACKGROUND: Embryos with greater viability have a lower or 'quieter' amino acid metabolism than those which arrest. We have hypothesized this is due to non-viable embryos possessing greater cellular/molecular damage and consuming more nutrients, such...
