Chao ChenChao Chen

Chao received her Bachelor's degree from Wuhan University in China. She is now working on the project of SoxC genes' role in cerebral cortex development in the lab of Dr. Maria Donoghue. The Sox gene family encodes a large group of transcription factors, classified by sequence homology into groups A through E. All Sox proteins contain a high mobility group (HMG) box, a region responsible for protein-protein interactions as monomers form dimers in order to bind DNA. SoxC group genes have been implicated in several processes during neural development, but the specific roles played by SoxC genes in the mammalian cerebral cortex remain unclear. Chao's research focuses on the roles of two SoxC genes, Sox4 and Sox11, in cerebral cortical development.
