A genome-scale map of DNA methylation kinetics

While the first genome-wide DNA methylation map in mammalian cells was established over 10 years ago, such maps only provide snapshots and do not inform about the actual dynamics of this epigenetic mark. Researchers from ...

Scientists sharpen gene editing tool

Wake Forest Institute for Regenerative Medicine scientists have fine-tuned their delivery system to deliver a DNA editing tool to alter DNA sequences and modify gene function. The improved "hit and run" system works faster ...

What causes rats without a Y chromosome to become male?

A look at the brains of an endangered spiny rat off the coast of Japan by University of Missouri (MU) Bond Life Sciences Center scientist Cheryl Rosenfeld could illuminate the subtle genetic influences that stimulate a mammal's ...

Stem cells organize themselves into pseudo-embryos

The definitive architecture of the mammalian body is established shortly after implantation of the embryo in the uterus. The antero-posterior, dorso-ventral and medio-lateral axes of the body become organized under the control ...

Artificial enzyme can activate a gene switch

Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene ...

Researchers find genetic 'dial' can control body size in pigs

Researchers from North Carolina State University have demonstrated a connection between the expression of the HMGA2 gene and body size in pigs. The work further demonstrates the gene's importance in body size regulation across ...

Plants fix DNA differently from animals

In mammalian cells, the transcription factor p53 most responsible for healthy growth of the organism. The equivalent in plants is Suppressor Of Gamma Response 1 (SOG1), a factor that does not share a common evolutionary ancestor ...
