One Man’s Junk DNA is Another’s Intronic microRNA

September 3, 2013

Introns have a bad rap these days. Sequestered with the rest of the (epi)genome in the term ‘junk’ DNA’; A reductionist way of describing 95% of our beloved genome as useless. But as new evidence keeps pointing out, introns and ‘non-coding’ regions actually code for most of the genomes products and/or function. In recently published […]

RRBS and 450k Arrays Face Off Over DNA Methylation Analysis

August 27, 2013

DNA methylation has been a cornerstone of epigenetics research from the start, and the emergence of technologies that make investigation of the modification more accessible has only made the DNA methylation field even hotter. Several tools and techniques are available to assess DNA methylation levels, but two in particular, reduced representation bisulfite sequencing (RRBS) and […]

Webinar: Life Long Changes in DNA Methylation & ncRNAs in Fetal Alcohol Syndrome (FAS)

August 22, 2013

Western University’s Ben Laufer (Ph.D. Candidate) discusses how bioinformatic software was used to establish that even moderate exposure to alcohol during pregnancy, equivalent to a few beers every now and then, can produce profound and heritable variations in development, behaviour, and learning that are maintained in the exposed fetus for a lifetime by altered epigenetic […]

R-loops: RNA-DNA Hybrids Making Noise on Silenced Genes

August 21, 2013

Prader-Willi syndrome and Angelman syndrome are like two-peas-in-a-pod, the textbook cases of the power of genomic imprinting. However, some consider them to be distinct genetic disorders that are grouped together, as Dr. Janine LaSalle (UC Davis) puts it; “Only because of the shared chromosomal location of deletions to 15q11-13 and ‘quirky’ oppositely imprinted inheritance patterns.” […]

MECP2 Therapy Deployed to Reverse Rett Syndrome Symptoms

August 21, 2013

They say that cats have nine lives. If that’s true then the idea of ‘Gene Therapy’ must be part feline. Despite several hurdles over the years, gene therapy once again captured the spotlight; this time by demonstrating that replacing mutated MECP2 can reverse the symptoms of Rett Syndrome in mice. The new research led by […]

Genomic Editing and lncRNAs Team Up Against Down’s Syndrome

August 20, 2013

According to breakthrough research, families affected by Down’s Syndrome may one day have the opportunity to alleviate many of the syndrome’s harmful aspects. Regardless of the ethical concerns around this treatment, which we won’t debate here, we think just the approach and mechanism developed within this study are worthy of a shout out. A cunning […]

Methylation Maps Pinpoint Epigenetic Differences in Human Tissues

August 19, 2013

It’s easy to get overwhelmed by just how much data an epigenome can hold. It’s hard to decide exactly where to start studying DNA methylation. Assaying every CpG site in the genome just isn’t practical for most researchers and a lot of money is spent on obtaining uninformative data. “Owing to the relatively small fraction […]

Fetal Stress: The Imprinting of Generations

August 13, 2013

Stress gets to us all on occasion. Whether it’s the more familiar stress that leads to hair-tearing-out, or some other version like coping with a bully, plants dealing with temperature changes, or even alcohol exposure as a fetus, stress has been shown to have profound effects on individuals down to an epigenetic level. But as […]

RRBS Dives Deep into Zebrafish Brain Methylomes

August 12, 2013

Get ready for the Zebrafishnado! OK, a tornado filled with cute little aquarium fish isn’t nearly as terrifying as a Sharknado, but a whirlwind of new data on zebrafish methylomes did reveal that their DNA methylation patterns are pretty unique compared to other species, including humans. Scientists from New Zealand realized that no one had […]

DNA Methylation Adds Variety to Human Populations

August 7, 2013

If variety is the spice of life, then DNA methylation sure seems to be supplying some of the flavor. A new study shows that DNA methylation isn’t just responsible for the differences in individuals, but for variations in populations as well. We’re no strangers to the way that DNA methylation can differ in diseases and […]
