Join the HJF Team!

HJF is seeking a Postdoctoral Fellow - Informatics/Biomarker/Mouse Genetics/Cancer Immunology to support the lab of Dr. Geeta Upadhyay within the Department of Pathology located at Uniformed Services University of Health Sciences (USUHS) in Bethesda, MD. HJF provides scientific, technical and programmatic support services to USUHS. 

The postdoctoral candidate will have the opportunity to conduct some of the research described in our newly funded R01 grant title “Role of Ly6K in TGF-beta and immune escape pathways of triple negative breast cancer”. Ly6K, a GPI anchored protein, is expressed in cancer tissue and is required for in vivo tumor progression. We have shown that Ly6K activates TGF-beta signaling, epithelial-to-mesenchymal transition and PD-L1 expression. We found that knockdown or pharmacological inhibition of Ly6K by small molecules binders, can significantly inhibit multiple distinct aspects of the biological activity of Ly6K. This proposal will be focused on determining the molecular basis of Ly6K action and Ly6K targeted therapeutics. In addition, they will be provided to develop new projects focused on drug resistance and drug development focused on Ly6E and other members of this family.
