Prof. Orna Elroy-Stein is a Full professor in the Department of Cell Research and Immunology at the Faculty of Life Sciences, Tel Aviv University, and a member of the Sagol School of Neuroscience. She received her B.Sc. and M.Sc. from the Technion, her Ph.D. on Human Molecular Genetics at the Weizmann Institute of Science, Israel, and her postdoctoral training at the Lab of Viral Diseases, NIAID, Maryland, USA.


Research Interests

The lab is engaged with various research topics, all related to regulation of mRNA translation in mammalian cells in health and disease.  Regulation of gene expression at the level of mRNA translation into proteins is fundamental to growth, differentiation and development of multi-cellular organisms. We are interested in:

  • the molecular mechanisms that govern global rates of protein synthesis in response to physiological and stress signals;
  • and the molecular mechanisms regulating the translation of specific mRNAs.
