A New Target for a Deadly Childhood Cancer
Figure reproduced under the Creative Commons Attribution 4.0 International License 4.0 from A. M. Weissmiller, et al. Nat. Comm., (2019) 10, 2014. SWI/SNF is a multicomponent protein complex that plays an important role in chromatin remodeling. It is also likely an important tumor suppressor, as indicated by the fact that… Read MoreJun. 12, 2019

Functional Insights Into a Major Drug-Resistance Transporter
As a member of the class of ABC (ATP-binding cassette) transporters, the P-glycoprotein (P-gp) harnesses energy from ATP hydrolysis to power conformational changes that transfer substrates across the cell membrane against a concentration gradient. P-gp transports more than 200 structurally diverse substrates, thereby playing a role in the pharmacokinetics of… Read MoreMay. 30, 2019

Taming the Fear Response
The Scream, Edvard Munch, PD-US-expired. Disorders arising from trauma and stress, such as post-traumatic stress disorder (PTSD), are a major cause of morbidity and mortality, and they exact a huge economic toll on our society. Hence, a major effort is underway to find new treatments for these diseases. A clue… Read MoreApr. 30, 2019

A new framework for genome-wide association studies
A multi-institutional team of researchers, led by Basic Sciences faculty member Bingshan Li (Molecular Physiology & Biophysics), has developed a new framework that can help researchers learn more from genome-wide association studies (GWAS) than previously was possible. Their work was published in Nature Neuroscience. Read MoreApr. 25, 2019

Controling RNA Polymerase Dynamics
Reproduced from Wikimedia Commons through the Creative Commons CC BY-SA 3.0. The process of transcription is extremely complex, requiring the well-coordinated interactions of numerous modulatory proteins and protein complexes. Two key players in this process are cyclin-dependent kinase (CDK)7 and CDK9, both of which phosphorylate multiple sites on RNA polymerase… Read MoreMar. 22, 2019

Targeting the WIN Site of WDR5
Proposed mechanism of WIN site inhibition. The inhibitor (i) binds to the WIN site of WDR5, displacing it from its binding site on chromatin. A major result is a decrease in transcription of genes encoding ribosomal proteins (RPGs), leading to a disruption of protein synthesis, the nucleosomal stress response, and… Read MoreMar. 21, 2019

In Search of Synergy
In recent years, the number of complex diseases such as cancer and drug resistant infections that are treated with multiple drugs has rapidly increased. Through combining drugs, one hopes to obtain synergy either by increasing potency (so the desired effect can be achieved with lower drug doses) or increasing efficacy… Read MoreMar. 15, 2019
