Abstract: A variety of epigenetic modifications including post-translational modifications (PTMs) on histone tails regulate gene expression and have profound effects on cell signaling and human disease. N-terminal histone tails can have a variety of modifications, such as phosphorylation, methylation and acetylation at specific amino acid residues which are conserved throughout eukaryotes and function by altering chromatin […]
Ever get that feeling that you forgot something? Well maybe you did, but it doesn't have to be recent epigenetics research if you scope out our Headlines each week.
Have you ever had a doubt about what exactly you can recycle? The cell is faced with the same problem when it encounters epigenetic nucleosides. It does not really know if they can be recycled as they are or discarded. New research by the team of Skirmantas Kriaucionis shows that although such nucleotides are normally […]
Life on Earth only uses 4 DNA bases (ACGT), but in principle, there’s no good reason why we couldn’t use more. Heeding the call of “this might be possible but nature hasn’t done it yet I wonder why not?”, synthetic biologists have been tinkering with synthetic bases to see if an expanded DNA alphabet […]
Traditionally, most bioproduction culture systems use just one strain of yeast or bacteria. Sometimes, though, you just need a little help from your friends. That’s the idea behind the emerging field of synthetic ecology, which just achieved a major proof-of-principle success thanks to a team of MIT scientists. Cocultures have been used in specific cases […]
We recently brought you news of an exciting study led by Juan Carlos Izpisua Belmonte in which his group successfully eliminated mutant mitochondrial (mt)DNA in oocytes to inhibit germline transmission of currently incurable mitochondrial diseases. Well he’s back, and this time he brought a friend. Shoukhrat Mitalipov has teamed up with Izpisua Belmonte in a […]
