Role of Epigenetics in Changing the Behaviour of carpenter ants


Ants give ideal models to review social behavior, as a result of every colony consists of thousands of individual sisters -- splendidly, the queen and all workers are female -- with nearly identical genetic makeup, very similar to human twins. However, these sisters possess stereotypically distinct physical traits and behaviors supported caste. In a previous study, the authors created the primary genome-wide epigenetic maps in ants. This unconcealed that epigenetic regulation is vital to identifying majors because the "brawny" soldiers of carpenter ant colonies, compared to minors, they're smaller, "brainier" sisters. Major ants have giant heads and powerful mandibles that facilitate to defeat enemies and process and transport giant food things. Minor ants are a lot of smaller, outnumber majors 2 to 1, and assume the vital responsibility of looking for food and recruiting alternative ants to assist with the harvest. Compared to majors, these foraging minors have genes concerned in brain development and neurotransmission that are overexpressed.
In the new findings, an knowledge domain analysis team led by senior author Shelley Berger, PhD, from the Perelman school of medicine at the University of Pennsylvania, in collaboration with teams led by Juergen Liebig from Arizona State University and Danny Reinberg from New York University, found that caste-specific hunt behavior is directly altered, by dynamical the balance of epigenetic chemicals referred to as acetyl groups attached to histone} protein complexes, around that DNA strands, are wrapped during a cell organ. To reveal this exquisite management, the team incontestable that hunt behavior can be reprogrammed victimization compounds that inhibit the addition or removal of those acetyl groups on histones (histone acetylation), successively dynamic the expression of near genes.

"The results recommend that activity physical property in ants, and certain alternative animals, could also be regulated in an epigenetic manner via simple protein modification," said lead author Daniel F. Simola, Ph.D., a postdoctoral researcher in the Penn Department of Cell and Developmental Biology. Simola is the co-lead author with Riley Graham, a doctoral student in the Berger lab.

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}
