New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.

Plant Research Reveals Unexpected Function for Key Cellular Protein

A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's genetic code expresses itself. The fundamental breakthrough was discovered in apple cells but is relevant to all living organisms made of nucleus-containing cells, including humans.

Histone H3K9 Methylation Found to Act as a Dimmer Switch for Gene Regulation

Researchers led by Kannosuke Yabe, Asuka Kamio, and Soichi Inagaki of the University of Tokyo have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via the interactions of two other proteins and histone marks.
