Washington University School of Medicine (WUSM), WUSTL

Postdoctoral Fellowship in the Redox Biology of Breast and Lung Cancer

Jason Held

Saint Louis, MO, United States

A postdoctoral position is open immediately in the laboratory of Dr. Jason M. Held at the Washington University School of Medicine in St. Louis, MO. The Held Laboratory focuses on redox systems biology and signaling in cancer and is especially interested in the redox regulation of cysteines. This interdisciplinary position is focused on understanding the mechanistic role of NADPH oxidase- and mitochondrial-derived reactive oxygen species (ROS) in cellular transformation, migration, cell polarity and signaling in breast and lung cancer models. It will also utilize optogenetics to precisely control the space and time of intracellular ROS production in order to systematically explore redox signaling networks activated by receptor tyrosine kinases and mitochondria. Techniques include cell-based and in vivo assays, DNA cloning, CRISPR/Cas9, and functional studies as well chemical biology, proteomics, and optogenetics.

Selected publications:

  • Redox Systems Biology: Harnessing the Sentinels of the Cysteine Redoxome (Preprint)
  • Spatial and Temporal Alterations in Protein Structure by EGF Regulate Cryptic Cysteine Oxidation (Preprint)

Link to the Held Lab website for a full list of publications and further information. We have a longstanding interest in applying new biochemical and informatic technologies to biological models.

Expertise in the following area(s) is preferred:

  • In vivo and in vitro cancer assays as well as rodent biology.
  • Molecular biology techniques, including CRISPR/Cas9 and viral transduction of human cells.
  • Prior experience in optogenetics, redox biology, LC-MS based proteomics and chemical biology isn’t required, but an interest in pursuing these techniques is essential.

Education requirements

A PhD., M.D. or equivalent terminal or doctoral degree in cancer biology, redox biology, NADPH oxidases (NOX), mitochondria and/or redox signaling.
