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 ...

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 ...

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 ...

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow 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 ...

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

Scientists at the MRC Laboratory of Medical Sciences (LMS) have discovered a DNA-based “dimmer switch” that regulates the activity of a critical developmental gene, Cdx2. This work could pave the way ...

Traditionally, cancer diagnosis and prognosis rely heavily on histopathological examination, where tissue morphology is evaluated under the microscope. However, the molecular ...

What if you could flip a genetic switch to silence a gene, then turn it back on with a simple drug? For researchers, gene-switch tools offer that kind of control—and a new system called Cyclone may ...

Revolutions in gene therapy are rapidly changing the landscape of modern medicine. Revolutions in gene therapy are rapidly changing the landscape of modern medicine, forcing society and science alike ...
