Ajit Bharti, PhD. Research Assistant Professor of Medicine:
Dr. Bharti received his PhD from Ranchi University, India. After a brief stint as a research scientist at the All India Institute of Medical Sciences, New Delhi, he joined Dr. Donald W. Kufe’s lab at the Dana-Farber Cancer Institute. After post-doctoral training, he continued to work as an instructor and contributed to understand the DNA-damage response pathway, particularly DNA-DSB caused by topoI inhibitors. TopoI inhibitors are used extensively to treat solid tumors, however, the response rate is low and the drug resistance mechanism is not understood. Dr. Bharti’s lab defined the mechanism of resistance, identified topoI-pS10 as the key molecular determinant of this pathway, and validated that as a potential predictive biomarker for this class of drugs. This IHC-based biomarker is retrospectively validated in CRC and GC. The discovery of topoI-pS10 as a predictive biomarker will significantly enhance the clinical utility of topoI inhibitors and will change the response rate in patient population
