Scott Hawley wins George W. Beadle Award from Genetics Society of America

Oct 15 2012

KANSAS CITY, MO—R. Scott Hawley, Ph.D., Stowers investigator and Dean of The Graduate School of the Stowers Institute for Medical Research, has been selected to receive the 2013 George W. Beadle Award for his outstanding contributions to the community of genetics researchers, the Genetics Society of America announced today.

Moving toward regeneration

Stowers scientists show how pluripotent stem cells mobilize in wounded planarian worms, to better understand stem cell behavior in regeneration and disease

KANSAS CITY, MO—The skin, the blood, and the lining of the gut—adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely unanswered.

Oversized fat droplets: too much of a good thing

Stowers investigators define factors that regulate size of cellular fat pools

KANSAS CITY, MO—As the national waistline expands, so do pools of intra-cellular fat known as lipid droplets. Although most of us wish our lipid droplets would vanish, they represent a cellular paradox: on the one hand droplets play beneficial roles by corralling fat into non-toxic organelles. On the other, oversized lipid droplets are associated with obesity and its associated health hazards.

Controlling gene expression: how chromatin remodelers block a histone pass

Aug 27 2012

Researchers show how repressor proteins ensure accurate gene expression by thwarting histone exchange.

KANSAS CITY, MO—Two opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA. Their repressor opponents antagonize that effort by twisting DNA into an inaccessible coil around histone proteins, an amalgam called chromatin, effectively blocking access to DNA by enzymes that elongate an RNA strand.

Ready. Get set. Repress!

Stowers scientists manipulate the Set2 pathway to show how genes are faithfully copied.

KANSAS CITY, MO—The first step in gene expression is the exact copying of a segment of DNA by the enzyme known as RNA polymerase II, or pol II, into a mirror image RNA. Scientists recognize that pol II does not transcribe RNA via a smooth glide down the DNA highway but instead encounters an obstacle course of DNA tightly wound around barrier proteins called histones. Those proteins must be shoved aside for pol II to trundle through. 

Stowers Institute ranked among top three places to work worldwide

Aug 1 2012

KANSAS CITY, MO—The Stowers Institute for Medical Research clocks in among the top three institutions in the annual “Best Places to Work in Academia” survey by The Scientist magazine. The Stowers’ excellent research resources, as well as its management and policies, aimed to encourage an interdisciplinary and collaborative environment, were cited as key factors why scientists working at the institute not only love their work, but also their workplace.

Stowers team reconciles puzzling findings relating to centromere structure

KANSAS CITY, MO—Scientists at the Stowers Institute of Medical Research have developed an innovative method to count the number of fluorescent molecules in a cluster and then applied the novel approach to settle a debate rampant among cell biologists—namely, how DNA twists into a unique chromosomal structure called the centromere. Knowing this helps explain how cells navigate the hazards of division and avoid the disastrous consequences of ending up with the wrong number of chromosomes.

The Yin and Yang of stem cell quiescence and proliferation

Non-canonical Wnt-signaling maintains a quiescent pool of blood-forming stem cells in mouse bone marrow

KANSAS CITY, MO—Not all adult stem cells are created equal. Some are busy regenerating worn out or damaged tissues, while their quieter brethren serve as a strategic back-up crew that only steps in when demand shoots up. Now, researchers at the Stowers Institute for Medical Research have identified an important molecular cue that keeps quiescent mouse hematopoietic (or blood-forming) stem cells from proliferating when their services are not needed.

Stowers Institute launches Original Data Repository

Jul 13 2012

The Stowers Institute for Medical Research announces the public launch of the Stowers Original Data Repository (ODR). As a strong supporter of the scientific ideals of transparency and openness, the Stowers Institute believes that the data underlying its published work should be freely accessible to the scientific community.
