Haynes lab members present research at the 2021 SEED conference

Posted on Updated on

SEED2017Four members from the Haynes lab presented their latest research at the 2021 Synthetic Biology: Engineering, Evolution & Design (SEED) conference that took place June 16 – 18, 2021 on a virtual platform. SEED 2021 focused on advances in science, technology, applications, and related investments in the field of synthetic biology. Dr. Karmella Haynes served as session chair for “Translating Synthetic Biology into the Clinic” and the “Funder’s Panel.” The four poster presentations from the Haynes lab included:

  • Dr. Isioma Enwerem (postdoc), “Time-course expression profiling reveals early and late responders to a synthetic chromatin regulator”
  • Harrison Priode (research specialist), “Synthetic epigenetic reader engineering with an all-in-one cell-free expression and protein interaction microarray”
  • Paige Steppe (undergraduate researcher), “Using newly-identified epigenetic reader-effector BAHCC1 to engineer a H3K27me3-binding transcriptional activator”
  • Dr. Natecia Williams (senior research specialist), “A synthetic chromatin reader-effector activates key silenced tumor suppressor genes in triple negative breast cancer cells”

Paige Steppe receives 2021 NSF GRFP award

Posted on

Undergraduate researcher Paige Steppe has received a 2021 National Science Foundation Graduate Research Fellows Program (NSF GRFP) award! This highly competitive award recognizes and supports outstanding students in STEM disciplines who are pursuing research-based graduate degrees at US institutions. The five-year fellowship includes three years of financial support including an annual stipend of $34,000 and $12,000 for tuition support. Paige is a college senior in the Chemical and Biomolecular Engineering program at Georgia Tech. She joined the Haynes lab in 2020 to investigate the evolutionary diversity of a chromatin-binding protein motif to inform rational design of synthetic epigenetic regulators in cancer. Congratulations, Paige!

Congratulations to Dr. Brady Laughlin, M.D.

Brady Laughlin, a former undergraduate researcher in the Haynes lab at ASU has earned his M.D. from the University of Arizona College of Medicine this year. Previously at ASU, Brady was an undergraduate Biomedical Engineering major and a Barrett Honors student. He did chromatin engineering research as a FURI Fellow in the Haynes lab and also gained research experience as a TGen Helios Scholar. He is now a resident in radiation oncology at the Mayo Clinic. Congratulations, Dr. Laughlin!

Research – Frontiers – Engineered orthogonal quorum sensing systems for synthetic gene regulation

Engineered orthogonal quorum sensing systems for synthetic gene regulation
Tekel SJ, Smith CL, Lopez B, Mani A, Connot C, Livingstone X, Haynes KA. (2019) Front Bioeng Biotech. 7:80.
PMID: 31058147 | PMCID: PMC6478669

For the past two years, the undergraduate ASU International Genetically Engineered Machines (iGEM) Competition teams have been investigating the use of quorum sensing to build bacteria (E. coli) that can carry out chemical signaling with each other, without signaling to a different group of bacteria. In a continuation of the quorum sensing project from the 2016 team, the 2017 ASU iGEM team built and tested six new quorum sensors (Receivers) in addition to the previous sensor, LuxR. After exposing a total of seven Receivers to HSLs from ten different synthases (Senders), the team identified two sets of signaling pathways that exhibited orthogonal behavior. These results expand the toolbox of characterized components for engineering microbial communities. The plasmid constructs featured in this paper were contributed to public collections for use by the scientific community.

Research – PLOS ONE – Characterization of Diverse Homoserine Lactone Synthases in Escherichia coli

Posted on Updated on

Characterization of Diverse Homoserine Lactone Synthases in Escherichia coli
Daer R, Barrett CM, Melendez EL, Wu J, Tekel SJ, Xu J, Dennison B, Muller R, Haynes KA. (2018) PLOS ONE. doi:10.1371/journal.pone.0202294
PMID: 30138364 | PMCID: PMC6107141

The Haynes lab focuses on advanced chromosome engineering in human cells, but also provides opportunities for undergraduates to learn synthetic biology using simpler organisms like bacteria (E. coli). In this paper, the 2016 ASU International Genetically Engineered Machines (iGEM) Competition team and their graduate advisors report their work to identify useful, new cell-cell communication components to use in engineered systems. Homoserine lactone (HSL) synthases appear as a wide variety of different forms in the bacterial kingdom, and produce various chemical signals that regulate genes in neighboring bacteria. When these are combined to build synthetic circuits in a common lab strain (E. coli), the signals are sometimes not produced as expected. Therefore, it is important to systematically characterize HSL synthases in context. The team also used experiments to identify the most effective way to neutralize unused HSLs in biological waste. The ten HSL synthases characterized in this paper were contributed to public collections for use by the scientific community.
