►This peer-reviewed review discussed how to measure cancer hallmarks in individual cells with an emphasis on quantifying altered cell signaling.  It updated Irish et al., Nature Reviews Cancer 2006 and Krutzik et al., Clinical Immunology 2004 to include solid tumors & mass cytometry.

Deon’s co-first author paper in Cytometry B:

Leelatian N*, Doxie DB*, Greenplate AR, Lehman JM, Sinnaeve J, Mobley BC, Kauffmann RM, Werkhaven JA, Mistry AM, Weaver KD, Thompson RC, Massion PP, Hooks MA, Kelley MC, Chambless LB, Ihrie RA, Irish JM. Single cell analysis of human tissues and solid tumors with mass cytometry. Cytometry B. PMC5459378. Pubmed. DOI.  *equal contribution, co-first authors.

► This peer-reviewed methods research was conducted in collaboration with Rebecca Ihrie and was the first published application of flow-based mass cytometry to solid human tissues.  This study validated mass cytometry for human solid tumors, including glioblastoma, melanoma, and patient derived xenografts (PDX) of small cell lung cancer.  This paper was recently selected as the “Editor’s Best” pick for 2017 — congrats Deon and Nalin!

If you’re thinking about doing any single cell work with solid tumors, a detailed protocol for the methods established here was published in Leelatian et al., Current Protocols 2017.  This protocol works with scRNA-seq, PDX, phospho-flow, and other approaches (in addition to mass cytometry).

In addition to the first-author papers above and work in review, Deon also co-authored the following at Vanderbilt:
