Role of epigenetics in evolution of memory and learning in reference of Songbird’s

A well-known songbird, the great tit, has discovered its genetic code, providing researchers new insight into how species adapt to an ever-changing planet. Their initial findings recommend that epigenetics -- what's on instead of what's within the gene -- might play a key role within the evolution of memory and learning. And that is not simply true for birds. An international research team led by The Netherlands Institute of Ecology (NIOO-KNAW) and Wageningen University can publish these findings in Nature Communications. "People in our field are expecting this for many years," explain researchers Kees van Oers and Veronika Laine from The Netherlands Institute of Ecology. The reference genome of their favorite model species, the great tit, is "a powerful tool case that each one ecologist and evolutionary biologists should know about." Coming from one Dutch bird, the genetic code of the assembled reference genome can facilitate to reveal the genetic basis of phenotypic evolution. This can be essential for understanding how wild species adapt to our ever-changing planet.



In addition to looking at the genome, the research team has conjointly determined the so-called transcriptome and methylome. The latter belongs to the sector of epigenetics: the study of what you'll be able to inherit not in but 'on' your genes. Specific DNA sequences within the genome may be 'methylated': methyl groups are added to them, modifying how the genes perform. What that research has discovered are so-called conserved patterns of methylation in those same regions, present not only in birds however additionally in humans and different mammals. It's proof of a correlation between epigenetic processes like methylation and the rate of molecular evolution: "the more methylation, the more evolution. And so the great tit has another time proved that its role as a model species during a kind of biological research fields for over sixty years is by no means coincidental.

Histone Modification Landscape Pristine

Recycling represents one in every of the foremost necessary ways to keep the earth clean and green for generations to come back. Used paper, metal, and plastic and alternative different detritus typically encounter the second use, however, will we have a tendency to recycle the histone proteins that facilitate to package our DNA and maintain cell-type-specific transcriptional programs? A lean, clean, and green team led by Anja Groth (University of Copenhagen, Denmark) couldn´t let such a tantalizing question goes to “waste”, and then they developed a brand new  genome-wide  technique (ChOR-seq) to investigate chromatin occupancy after DNA replication by next-generation sequencing. ChOR-seq tracks usage of “old” histones and directly measures the replication-dependent displacement of pre-existing histone modifications by using a combination of pulse labeling of replicating DNA with a nucleotide analog and also the data that recently synthesized histones lack tri-methylation modif

Consumption of Tea leads to Epigenetic changes in women

Image
It is well-known that our surroundings and lifestyle factors, like food selections, smoking, and exposure to chemicals, will cause epigenetic changes. In the current study, researchers from Uppsala University together with research teams around Europe investigated that coffee and tea consumption might cause epigenetic changes. Previous studies have advised that both coffee and tea play a vital role in modulating disease-risk in humans by suppressing tumor progression, decreasing inflammation and influencing estrogen metabolism, mechanisms which will be mediated by epigenetic changes. The results show that there are epigenetic changes in ladies consuming tea, however not in men. Curiously, several of those epigenetic changes were found in genes concerned in cancer and estrogen metabolism. "Previous studies have shown that tea consumption reduces estrogen levels that highlight a possible distinction between the biological response to tea in men and ladies. Weronica Ek, a

Brain development controlled by epigenetic factor

Image
McGill researchers have discovered, for the first time, the importance of a key epigenetic regulator within the development of the hippocampus, a component of the brain related to learning, memory, and neural stem cells. An epigenetic regulator modifies the way specific genes perform while not fixing their deoxyribonucleic acid sequence. By operating with mutant mice as models, the analysis team, led by a professor. Xiang-Jiao Yang, of McGill's Goodman Cancer Center & Department of Medicine, McGill University health center, was able to link the importance of a particular epigenetic regulator called BRPF1 to the healthy development of a section within the hippocampus known as the dentate gyrus. This discovery sheds light on however epigenetic management and neural stem cells could also be concerned in regulation human brain development, and has implications for intellectual incapacity in human patients, in addition as for medical disorders like Alzheimer's disease}
