Dr. Haynes has been invited to speak at the 3rd Synthetic Biology Congress on October 20 – 21, 2016 in London, UK. She will present “Regulation of cancer epigenomes with a histone-binding synthetic transcription factor.” The Synthetic Biology Congress will highlight the latest developments in genome engineering, technological development, cell building, bio-manufacturing and gene editing. The meeting will host experts from across the globe who specialize in healthcare and plant biology.

Slides from Dr. Haynes’ presentation, as well as other talks, are available online: http://www.globalengage.co.uk/synthetic/pr16.html

Dr. Haynes Invited to “aGEM” Workshop in Canada

Posted on

geekstartercmyktransparentcroppedDr. Haynes has been invited to Alberta, Canada to evaluate and offer guidance for several student synthetic biology projects at the aGEM workshop, organized by Alberta Innovates Technology Futures. The workshop prepares Canadian high school and college teams for the International Genetically Engineered Machines (iGEM) competition in October. “aGEM” (Alberta’s own mini-iGEM) is presented by MindFuel and the GeekStarter program, which helps the next generation of scientists innovate new technologies. Student teams apply to the program in order to receive funding and access to GeekStarter events. The aGEM workshop takes place at the University of Calgary, Foothills Campus on September 17 – 18, 2016.

Rene Daer to present at the 2016 ASCB meeting

Posted on

ASCB2016Haynes lab PhD student Rene Daer will present a talk at the 2016 American Society for Cell Biology (ASCB) meeting, one of the largest annual scientific meetings in the US. Her abstract “The impact of chromatin dynamics on Cas9-mediated genome editing in human cells,” was selected for an oral presentation in the Minisymposium entitled, “Use Synthetic Biology to Measure and Manipulate Cell Biology” under the topic Synthetic and Systems Biology. The meeting will be held at the Moscone Center in San Francisco, CA, from December 3-7.

Please consider registering for this conference. Poster abstracts will be accepted until October 13, 2016.

Research – Nature – Regulation of cancer epigenomes with a histone-binding synthetic transcription factor

This work expands our 2011 report in many important ways. We studied the behavior of a synthetic chromatin protein that we designed called PcTF in bone, blood, and brain cancer-derived cells. We expected to see PcTF bind to methylated histones, but instead saw strong signals closer to histone-free gene promoters. However, PcTF activity still required the methyl-histone binding domain to interact with its targets. It appears that PcTF bridges methylated histone signals with the transcription complex. We also discovered that PcTF activates a key tumor suppressor, CASZ1 as well as other silenced genes in all three cancer cell types. This new information has advanced our understanding of how a potentially therapeutic histone-binding protein behaves in cancer cells.
