Stage fright: don't get over it, get used to it

Many can feel empathy with the situation Banerjee describes: facing “a room full of scientists, who for whatever reason, did not look very happy that Read more

Beyond birthmarks and beta blockers, to cancer prevention

Ahead of this week’s Morningside Center conference on repurposing drugs, we wanted to highlight a recent paper in NPJ Precision Oncology by dermatologist Jack Arbiser. It may represent a new chapter in the story of the beta-blocker propranolol. Several years ago, doctors in France accidentally discovered that propranolol is effective against hemangiomas: bright red birthmarks made of extra blood vessels, which appear in infancy. Hemangiomas often don’t need treatment and regress naturally, but some can lead Read more

Exosomes as potential biomarkers of radiation exposure

Kishore Kumar Jella, PhD

Winship Cancer Institute postdoc Kishore Kumar Jella has been invited to speak at the NATO advanced research workshop BRITE (Biomarkers of Radiation In the Environment): Robust tools for Risk Assessment in Yerevan, Armenia, on 28-30 November, 2017. The workshop brings together leading international experts to evaluate currently and developing radiation biomarkers for environmental applications.

Jella works in the Departments of Biochemistry and Radiation Oncology under the direction of Professors William S. Dynan and Mohammad K. Khan. He will speak on “Exosomes as Radiation Biomarkers”. He will describe how radiation influences exosome production and how these exosomes influence the immune system. The work has applications both to radiation carcinogenesis and combination radio-immunotherapy.

Jella is supported in part by a grant from the National Aeronautics and Space Administration to Dynan.

Exosomes are nano-sized membrane-clothed capsules containing proteins and RNA that are thought to facilitate cell-cell communcation. They were previously implicated in the ability of cancer cells to influence healthy neighbor cells, and have also been proposed as anti-cancer therapeutic vehicles. Jella’s previous research on exosomes and radiation-induced bystander signaling was published in Radiation Research in 2014.
