Bees Model Their Potential for Epigenomic ResearchApril 13, 2015With spring in the air, the honeybees are already out and buzzing about and now an international team from Australia and Poland have created a different type of buzz with their research into 5hmC and its effect of bee’s behaviour. The importance of epigenetics in bees has already been suggested with the finding that honeybees use miRNAs to enable their […]
DNMT1 Loss is Lethal in Human But Not Mouse Embryonic Stem CellsApril 2, 2015Mouse models have been great to science, they’ve given insight into humans in ways simply not possible in humans. However, while there are striking similarities in the epigenetics of mice and men, there are also undoubtedly some fundamental differences. Now, a team from the Broad Institute of MIT and Harvard consisting of the labs of Alexander Meissner, J. Keith Joung, and John […]
Sex On the Brain: DNA Methylation Defines GenderMarch 31, 2015A talented team from the University of Maryland has added some strong molecular evidence that DNA methylation is an active player in setting the sexual behaviors you’re born with. Sexuality has always been a complex topic. Typically it refers to presence or absence of certain sex organs. However, the concept of gender is more complex, as […]
The Long Route of MeCP2 in TranscriptionMarch 24, 2015A number of teams have already spent time in trying to uncover the path that leads from MeCP2 disruption to Rett syndrome, a severe neurodevelopmental disorder in the autism spectrum. Adding detail to MeCP2’s repressive function, a team led by Michael Greenberg gathered data from MeCP2 mouse mutants and patient samples, finding an unexpected clue in long-gene […]
5hmC: a Helping Hand in Drug AddictionMarch 23, 2015While there’s no doubting that one month of continuous cocaine exposure is going to have an effect on the brain, it seems that some of the molecular culprits behind the response and long-term effects are 5hmC and the TET protein family. An international research team studying addiction via cocaine show that repeat exposure downregulates the TET machinery in the brain’s reward centre, the nucleus […]
