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 ...

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 ...

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 ...

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 ...

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 ...

Explore RNA interference methods, comparing siRNA and shRNA for gene knockdown, their mechanisms, advantages, and ...

A research team has identified the core gene expression networks regulated by key proteins that fundamentally drive phenomena such as cancer development, metastasis, tissue differentiation from stem ...

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 ...

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

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