We study the deregulation of transcriptional pathways in human disease and finding small molecules to normalize or modulate these gene-expression patterns.

Top left: A diagram of histone interaction with the demethylase KDM5B. The histones are shown as four colored lobes inside a loop of a DNA helix, while KDM5B is a red ovoid outside the loop. An arrow goes from the ovoid to a methyl group on one of the histones.
Top right: Two images of cells stained with green fluorescent protein. One labeled DMSO+IR is sparsely stained. One labeled JIB-04 + IR is more heavily stained.
Bottom: Three long, thin rows of pixelated black, red, and green rectangles. The three rows are labeled Normal, Cancer, and +JIB-04

Jihan Osborne, Ph.D.

On the right, an outline of an adult human is next to a red neural cell with the label homeostatis. In between is an outline of a red circle with a dashed red arrow.

Michael Reese, Ph.D.

Lab Website • michael.reese@utsouthwestern.edu

Our laboratory studies how the ubiquitous parasite Toxoplasma gondii co-opts the cellular signaling of its hosts, and how evolutionary competition has shaped the signaling of both organisms.
