Dr. Tony Neff

Professor Emeritus, Anatomy and Cell Biology

I am currently interested in organ and tissue regeneration in amphibians with emphasis on limb regeneration.   I am particularly interested in the process of reprogramming (dedifferentiation) during limb regeneration and the role of the immune system in modulating the regeneration process.

  • Microenvironment-induced downregulation of miR-193b drives ovarian cancer metastasis

    Apr 28th, 2015

    Anirban K Mitra, Assistant Professor of Medical and Molecular Genetics has recently published his research in Oncogene. His study links paracrine signals from the microenvironment to the regulation of a key miRNA - miR-193b - in ovarian cancer cells, which promotes metastatic colonization.
