Dr. Mukesh Nyati has over twenty years of experience in basic and translational oncology. He is a tenured Associate Professor in the Department of Radiation Oncology at the University of Michigan, supervising junior faculty and post-doctoral fellows in the laboratory. His administrative responsibilities include the Cancer Biology Division’s daily operations and organizing weekly academic seminars as well as the Cancer Biology Course that prepares Radiation Oncology residents for their board exams. Dr. Nyati actively participates in the peer review process for many journals and the grant review process for NIH, NCI, DOD, SBIR, and STTR. He served as a consultant for CTEP for clinical development of AT13387 and AZT9291.
Dr. Nyati is involved in three major type of research.
The main focus of his research is investigating the role of protein stability in cancer progression and treatment. Dr. Nyati has been studying EGFR, cMet and KRAS oncogenes and agents that either block their activity or induce selective degradation of these oncoproteins. His group also studies the roles of the EGFR protein independent of kinase activity in cell growth and DNA repair. He is also part of the efforts of the Protein Folding Disease Initiative Group (https://research.medicine.umich.edu/research-strengths/protein-folding-diseases-initiative/research-hubs/targeting-chaperones) where he is investigating roles of Hsp90 chaperone machinery in DNA repair.
In a clinic-laboratory collaboration with Drs. Avraham Eisbruch and Shruti Jolly, Dr. Nyati is working to understand how a specific antibody (cetuximab) that binds with EGFR produces a clinical response in certain patients with head and neck squamous cell carcinoma but fails in other patients. Using patient samples taken before and during Cetuximab treatment, they are analyzing pharmacodynamic changes in EGFR and its associated signaling molecules, epigenetic markers, HPV status and immune response molecules. They then examine the relationships between each of these factors and the overall efficacy and toxicity of cetuximab treatment. The goal of this work is to identify patients most likely to respond to cetuximab therapy in combination with chemotherapy and/or radiotherapy early in the course of treatment.
Dr Nyati is working towards developing a novel agent that induces EGFR protein degradation by blocking EGFR dimer formation. Towards this, he developed a small peptide “Disruptin” that showed activity in TKI resistant lung tumor xenografts (Patent). He is currently developing small molecules that can degrade activated EGFR or mutant KRAS by blocking the protein-protein interactions that promote the stability of these oncoproteins.

Dr Nyati is also working with Dr Kyle Cuneo to develop a strategy to treat cetuximab-resistant, KRAS positive colorectal cancer patients.
Dr. Nyati is also an avid photographer (see Medical Campus in Moonlight above) with photos published in a wide range of journals, calendars and newspapers. He has secured funding for research from a variety of sources and published articles in Nature, Science, PNAS, Cancer Research, and JBC. Dr. Nyati has trained students, post-doctoral fellows and residents in the laboratory setting. He is also a co-founder of Pi Squared Therapeutics, LLC, a start-up biotechnology company focused on selective targeting of protein stability of activated oncogenes by disrupting protein-protein interactions required for cancer cell survival.
