February 2025 Spotlight: Orion Songe

Hi there! I am a second-year BCMB student in Dr. Junji Iwahara's lab and I earned my BS in biochemistry at Nicholls State University in Louisiana. I am researching the structural and biophysical impact of cysteine modifications on HMGB1, a potent signaling protein that binds to Toll-like receptor 4 (TLR4) to amplify inflammation. By utilizing NMR spectroscopy and circular dichroism spectrometry, I will study the structural differences in the HMGB1 protein based on chemical modifications to the Cys106 residue. Using SPR-based kinetic assays, I will better understand how the cysteine modifications affect HMGB1's ability to bind to TLR4 and disrupt the inflammatory pathway. My goal in the lab is to provide impactful research for chronic inflammatory diseases and provide deeper biophysical insight on a highly conserved and relevant protein. 

I was always a science lover and frequented science and arts museums and STEM camps, but I first got involved with research at my undergraduate institution. In this lab, I was focused on identifying transposable elements in the red swamp crawfish for easier comparison between native species and imported species. We utilized DNA purification and amplification techniques to separate the transposable elements and sequence them. I've also worked in protein biochemistry and biophysics during an REU at Texas State University, where I was studying liquid liquid phase separation of coilin, an intrinsically disordered protein implicated in neurodegenerative disorders. 

My interests and hobbies outside of the lab include creating art, whether by drawing or writing. I am actually working on a sci-fi novel right now during my down time between experiments and research. I aspire to be a published author one day alongside my research and scientific achievements.
