Cancerous tumors deliver pro-metastatic information in secreted vesicles
Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called ...

Scientists find mechanism that triggers immune responses to DNA
(Medical Xpress)—Free-floating pieces of DNA in a cell's watery interior can mean bad things: invading viruses, bacteria, or parasites, ruptured cellular membranes, or disease. Genetic material is meant to be contained ...

Cancer epigenetics: Breakthrough in ID'ing target genes
Cancer is usually attributed to faulty genes, but growing evidence from the field of cancer epigenetics indicates a key role for the gene "silencing" proteins that stably turn genes off inside the cell nucleus. ...

Nucleic acid
A nucleic acid is a macromolecule composed of chains of monomeric nucleotides. In biochemistry these molecules carry genetic information or form structures within cells. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are universal in living things, as they are found in all cells and viruses. Nucleic acids were first discovered by Friedrich Miescher in 1871.
Artificial nucleic acids include peptide nucleic acid (PNA), Morpholino and locked nucleic acid (LNA), as well as glycol nucleic acid (GNA) and threose nucleic acid (TNA). Each of these is distinguished from naturally-occurring DNA or RNA by changes to the backbone of the molecule.
