  • Transcription factors guide differences in human and chimp brain function

    Cell and developmental biology professor Lisa Stubbs, right, and postdoctoral researcher Katja Nowick and their colleagues found distinct differences in gene activity between humans and chimps. These differences are associated with about 90 transcription factors, they found.

      The study, in Proceedings of the National Academy of Sciences, found that broad differences in the gene activity of humans and of chimpanzees, affecting nearly 1,000 genes, appear to be linked to the action of about 90 transcription factors.
