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 ...

The new workflow was adapted from an enzymatic DNA tagging technology, DNA-TAG, previously developed in the Devaraj lab. In ...

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells.

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 ...

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 ...

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 ...

For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

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 ...

Delivery of therapeutic genes is essential for gene therapy. Adeno-associated viruses (AAVs) are a prime vector for carrying ...

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 ...

An extraction-free kit enables gene expression analysis directly from hepatocyte lysates, delivering results in 75 minutes with sensitivity comparable to RNA purification.
