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 ...

Salk Institute researchers find new mode of epigenetic targeting, showing for the first time that genetic sequences can direct new DNA methylation patterns in plants LA JOLLA (November 21, 2025)—All ...

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 ...

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 ...

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 ...

Researchers at the Jackson Laboratory (JAX), the Broad Institute of MIT and Harvard, and Yale University, have used artificial intelligence (AI) to design thousands of new DNA switches that can ...

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 ...
