TLDR
The first identification of several small-molecule inhibitors of human FTO demethylase is reported, including the most potent compound, the natural product rhein, which is neither a structural mimic of 2-oxoglutarate nor a chelator of metal ion.
Abstract
The direct nucleic acid repair dioxygenase FTO is an enzyme that demethylates N6-methyladenosine (m6A) residues in mRNA in vitro and inside cells. FTO is the first RNA demethylase discovered that also serves a major regulatory function in mammals. Together with structure-based virtual screening and biochemical analyses, we report the first identification of several small-molecule inhibitors of human FTO demethylase. The most potent compound, the natural product rhein, which is neither a structural mimic of 2-oxoglutarate nor a chelator of metal ion, competitively binds to the FTO active site in vitro. Rhein also exhibits good inhibitory activity on m6A demethylation inside cells. These studies shed light on the development of powerful probes and new therapies for use in RNA biology and drug discovery.

The dynamic epitranscriptome: N6-methyladenosine and gene expression control

TL;DR: This work has shown that m6A is present in a large subset of the transcriptome in specific regions of mRNA, which suggests that mRNA may undergo post-transcriptional methylation to regulate its fate and function, which is analogous to methyl modifications in DNA.

A common variant in the FTO gene is associated with body mass index and predisposes to childhood and adult obesity

TL;DR: A genome-wide search for type 2 diabetes–susceptibility genes identified a common variant in the FTO (fat mass and obesity associated) gene that predisposes to diabetes through an effect on body mass index (BMI).

Calculating Structures and Free Energies of Complex Molecules: Combining Molecular Mechanics and Continuum Models

TL;DR: A historical perspective on the application of molecular dynamics to biological macromolecules is presented and recent developments combining state-of-the-art force fields with continuum solvation calculations have allowed for the fourth era of MD applications in which one can often derive both accurate structure and accurate relative free energies from molecular dynamics trajectories.
