Bioelectronic ‘signatures?hold key to DNA mutations

...ind individual genetic variation and diseases like cancer are fine differences ?single nucleotide polymorphisms, or “SNPs??buried within the 3 billion chemical bases of DNA comprising the human genome. Not every SNP found will necessarily cause a mutation or determine our eye or hair color ?but, on average,...

New understanding of DNA repair may pave way to cancer treatments

...f radiation, as well as changes that take place in cancer and pathologic situations, can activate both functions of ATF2, which is expected to disturb the otherwise conserved balance between its role in gene regulation and the DNA damage response. We need to find out which of the two functions is more domin...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

... mechanisms that underlie many diseases, including cancer and septic shock. The discovery concerns tiny fragments of RNA known as microRNA and their relationship to the genetic transcripts known as messenger RNA (mRNA). All genes expressed in the human body must be transcribed as mRNA before they can be t...

Insight into DNA's 'weakest links' may yield clues to cancer biology
