  • Congratulations to Adel Adel for matching at the Midwestern Medical School in Arizona to embark upon his journey to become a physician. Well done, Adel!

January 2020 - December 2021:

We, as much of the world, found ourselves working amidst a raging pandemic. We were busy (see PubMed) and most in the group took the opportunity to rise and shine even brighter. Where others saw obstacles, we saw an opportunity to achieve goals that we did not think were possible. We hit the headlines many times (see see News). Some highlights are presented below for external coverage of our lab in the news.

December 2020:

Congratulations to Dr. Gajanan D. Katkar for receiving an Intersect Fellowship from the American Association of Immunology (AAI) for 2021. This 1-year long prestigeous fellowship is meant to support career lunch into computational immunology.

January 2018:

  • Congratulations to Nicolas Aznar and Jason Ear, and a team of their collaborators who just had their manuscript accepted at Science Signaling , describing how increasing growth factor signaling may flip a tumor suppressor protein [Daple] into a prometastatic oncogene during colon cancer progression. This work shows how Daple, which was initially found to have a Dr. Jeckyl and Mr Hyde sort of bifaceted role in epithelial cells, switches from one role to another.
  • Full Citation of the work: Convergence of Wnt, growth factor and trimeric G protein signals on Daple. Aznar N., Ear, J., [contributed equally], Dunkel Y., Satterfield K., He F., Kalogrioopulos N.

  • Mikel Garcia-Marcos and Pradipta Ghosh's work published in J. Biol. Chem (Feb 2010) was cited in Faculty of 1000 as "an interesting article that unequivocally demonstrates the structural basis for the mechanism by which G-alpha-i3 is regulated by GIV/Girdin, a novel non-receptor guanine-nucleotide exchange factor (GEF). The intriguing observation presented here may pave the way for the discovery of other GEFs that are potentially involved in the regulation of different members of the super-family of G proteins": Read entire commentary:
