Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

A collaborative effort has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many ...

A recent study led to the development of a powerful epigenetic editing technology. The system unlocks the ability to precisely program chromatin modifications at any specific position in the genome, ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

Researchers have unveiled a way to flip genes back on without slicing into the genome, a shift that could make CRISPR far ...

Toward the goal of efficient editing of farm animals for genetic improvements, this study explores an upgraded form of nuclease PE (uPEn). Based on an initial demonstration of its success in editing ...

Genetics is the study of genes and how they influence characteristics and health. Through a variety of technological methods, environmental factors, and lifestyle choices, it is possible to alter some ...
