The Epitranscriptome – A New Discovery In Gene Expression

Few breakthroughs in health science hold as much potential as the emerging field of epigenetics. No longer does the central dogma of genetics ring true – Our genes do not equal destiny anymore and our understanding of how to take control is growing, all thanks to a increasing understanding of gene expression. Environment and lifestyle can indeed affect if or how our genes express themselves. While our understanding of epigenetics continues to grow, a new breakthrough has come to light – the epitranscriptome and the role of the RNA.  Epitranscriptomics is a relatively new field in the world of genetics […]

Epigenetic “Memory” Gene Process Of Worms, Could Be Similar In Humans

  Epigenetics is the study of biological mechanisms that switch inherited genes on and off. The theory is that our own personal life experiences, or for that matter, those of our parents and our parent’s parents, are passed onto subsequent generations. Studies done on survivors from traumatic events, particularly events as catastrophic as ones such as the Holocaust have shown that exposure to stress have a follow-on effect on subsequent generations1. That is, the memory of these events is lived on through our progeny. Their DNA is impacted by the trauma as much as if they’d experienced it themselves. But […]

Addicted to Coffee?  New Study Shows It May Be In Your Genes.

Coffee, why is it that some people can take it or leave it? And others couldn’t imagine the start of their day without it? That ubiquitous, espresso brew has people world over obsessed with it. As it turns out, it may not simply be a love affair of the heart; it may be in your genes. Researchers from the Universities of Edinburgh and Trieste, from the Burlo Garofolo Paediatric Institute in Italy1 have made an interesting discovery. It’s called the PDSS2 gene. People with a DNA variation in this gene tend to drink fewer cups of coffee. The researchers looked […]

Fat Grandpas Pass on Love of Junk Food.

Story at a Glance. Overweight grandfathers impact the health of their grandsons. Grandsons given junk food negatively responded quite rapidly to the exposure of junk food showing fatty liver disease and pre-diabetic symptoms within a few weeks. The study showed a paternal link only. Epigenetics is the study of how inherited genes switch themselves on and off due to internal or external environments. And it’s in this area of science that has been looking at the harmful legacy parental obesity can pass on to future generations. With over 14 million Australians now obese, it’s food for thought.Blame it on the […]

Inheriting the Uninheritable.

Story at a Glance There are genetic causes of infertility that you can pass on through IVF. It means that the next generation may be infertile as well. Intra-Cytoplasmic Sperm Injection (ICSI) is a treatment for infertile men in which an individual sperm is selected and injected directly into an egg. Some studies suggest that IVF children born from ICSI may be at higher risk of medical problems, as they grow older, including male infertility.   Infertility affects 1 in 6 Australian couples. 40 percent of those problems will be due to sperm issues, 40 per cent will be because […]
