Epigenetic Clock Goes from Analog to iWatchFebruary 6, 2015Tick tock…we all know that life is a battle against the inevitability of time. But wouldn’t it be great if you could get a real idea of how your cells are aging? It may just help make 20 the new 30, that is when it comes to your chance of death. And that’s the ambitious […]
DNMT1 Depletion Helps Hunt for Heritable MethylationFebruary 5, 2015Sometimes it takes a special kind of guy to get the job done and when the job is to keep imprinted genes differentially methylated, that guy is DNMT1. An international group of researchers led by Jacquetta Trasler in Canada set out to exploit this fact in order to identify yet unknown imprinted genomic sequences. Several […]
Keeping Tabs on Off-Target Effects of Genome EditingFebruary 5, 2015While the fashion and music tastes of the late 1980’s was rather questionable, it was a time of historic technological and societal change. Between the breakdown of the Soviet Union and the rise of the global computer network that we now call internet, a small group of researchers succeeded for the first time in generating […]
From Neuron to Germline: Inheritance by Mobile RNAsFebruary 4, 2015We’ve got transgenerational epigenetic inheritance on the mind and now strangely enough it seems that the mind also causes transgenerational epigenetic inheritance?! Researchers have just shown the strangest case of inheritance yet: soma to germline. A talented team from the University of Maryland have been tracing double stranded RNA (dsRNA) in C. elegans and have made some interesting observations […]
Neurodevelopment and Methylomic Trajectories: Sex and DiseaseFebruary 4, 2015If variety is the spice to life than the brain must be the spiciest organ of them all, with DNA methylation as its rooster sauce (which comes with its own embedded sodium bisuflite conversion kit). By studying the delicious layers of DNA methylation variation we’ve seen strange parental expression biases, methylation differences between discordant twins, and how the dynamics […]
