Study highlights role of disordered protein interactions in gene expression

Scienmag

A team led by researchers at Baylor College of Medicine and the Czech Academy of Sciences has uncovered a new piece of the puzzle of how gene expression is orchestrated. Published in the journal Science, the findings reveal a novel mechanism that coordinates the assembly of components inside cells that control gene expression.

The Equalizer: An engineered circuit for uniform gene expression

Scienmag

The function of a protein can depend on its abundance in a cell. So, when investigating the properties of a new protein, it is essential to make sure that the same amount is produced by every cell. Researchers at Baylor College of Medicine and Rice University have found a new way to do just that […].

AI tool may help doctors select best drugs for COVID patients

pharmaphorum

Researchers in the US have developed an artificial intelligence-based tool that is able to predict COVID-19 symptoms and suggest which FDA-approved drugs might be used to treat patients. It could also be made more powerful by incorporating personal genetic information and gene expression profiles in tissues such as the lungs, they suggest.

Anti-convulsant drug can modify DNA conformation and interact with chromosome proteins

Scienmag

Brazilian research group shows that valproic acid (VPA), used to treat epilepsy since the 1960s, modulates gene expression in tumor gene models and acts on DNA conformation and the histones in chromatin Results of recent studies involving valproic acid, used for decades as an anti-convulsant drug, show that it can interact with the conformation of (..)

Discovery suggests new way to target mantle cell lymphoma

Medical Xpress

A form of blood cancer known as mantle cell lymphoma is critically dependent on a protein that coordinates gene expression, such that blocking its activity with an experimental drug dramatically slows the growth of this lymphoma in preclinical tests, according to a study from Weill Cornell Medicine researchers.
