Endeavors, the online magazine of research and creative activity at UNC, recently featured the work of Dr. Bob Duronio and iBGS.
The genome of a fruit fly is strikingly similar to that of a human — so much so that scientists have been studying these tiny insects for over 100 years, in search of treatments for diseases like spinal muscular atrophy and neurological disorders. UNC geneticist Bob Duronio is one of those scientists.
“It begins with curiosity. Curiosity about a process. And then a question about that process. And then a hypothesis that will lead to an experiment that will provide results and data to interpret. What I love about this process is that my hypotheses are often wrong. And that’s really exciting — because no human being is smart enough to understand biology at a level of molecular detail where their hypotheses are always right.”
-Bob Duronio, director of the Integrative Program for Biological and Genome Sciences
Robin Armstrong adjusts the focus on her dissecting microscope. Iridescent ovals float in the ether, clumped together, stark against a black backdrop. They look like the little, individual fibers that comprise the flesh of a grapefruit — long and plump and juicy. Though this grape-shaped bunch is far from produce, it’s fitting that they belong to a fruit fly. Armstrong is examining its ovaries.

A fruit fly wing, enhanced with red and green fluorescence to study genes involved in development over time.
The following article, highlighting the work of Daniel McKay, PhD appeared in the May 25, 2017 edition of UNC Health Care and UNC School of Medicine’s Vital Signs newsletter and highlights findings published in the June issue of Genes and Development.
Every animal starts as a clump of cells, which over time multiply and mature into many different types of cells, tissues, and organs. This is fundamental biology. Yet, the details of this process remain largely mysterious. Now, scientists at the University of North Carolina at Chapel Hill have begun to unravel an important part of that mystery.
Using the fruit fly Drosophila, a standard lab model for studying animal biology, the researchers discovered a cascade of molecular signals that program gene activity to drive the fly from one stage of maturation to the next, like a baby turning into an adult. Part of this programming, they found, involves alterations to the way DNA is packaged. Those alterations open up certain regions of DNA to allow gene activity and close off other regions to prevent gene activity. The scientists found evidence that these changes to DNA accessibility occur in sequence.
“We’re finally getting at one of the core mechanisms in biology, which determine the timing and sequence of events in normal animal development at the level of our genes,” said Daniel J. McKay, PhD, assistant professor of genetics at the UNC School of Medicine and biology at the UNC College of Arts and Sciences.

Duronio, McKay, Strahl, Matera co-authored the paper that appeared in the August 2016 publication of Genes and Discovery.
The following article, highlighting the work of Robert Duronio, PhD; Daniel McKay, PhD; Greg Matera, PhD; Brian Strahl, PhD., appeared in the September 1, 2016 edition of UNC Health Care and UNC School of Medicine’s Vital Signs newsletter and highlights findings published in the Volume 30, No. 15 release of Genes and Discovery.
UNC School of Medicine researchers discovered that the major developmental function of heterochromatin – a form of tight DNA packaging found in chromosomes – may be to suppress activity of virus-like DNA elements known as transposons or “jumping genes,” which can otherwise copy and paste themselves throughout the genome, potentially destroying important genes, and causing cancers and other diseases.

University of North Carolina scientists have created a new research tool, based on the fruit fly, to help crack the histone code. This research tool can be used to better understand the function of histone proteins, which play critical roles in the regulation of gene expression in animals and plants.
This work, published in the journal Developmental Cell, opens the door to experiments that are expected to uncover new biology important for a host of conditions, such as neurological diseases, diabetes, obesity, and especially cancer, which has become a hotbed of epigenetic research.
