Shanshan Pei, Ph.D
Principal Investigator
Dr. Shanshan Pei is currently a principal investigator at Liangzhu Laboratory and The First Affiliated Hospital of Zhejiang University. He previously worked as a Research Assistant Professor in the Division of Hematology at the University of Colorado. He received his bachelor’s degree from the University of Science and Technology of China and his Ph.D. degree from the University of Rochester School of Medicine.
He has been focusing on the basic and clinical translational research of human acute myeloid leukemia (AML) disease for more than 15 years. During his postdoc training with Professor Craig Jordan, a leading researcher in the field of leukemia stem cells (LSC), he revealed the critical mechanisms regulating mitochondrial dynamics and mitophagy activity required for the self-renewal ability of human LSCs. During his research assistant professorship at the University of Colorado, he focused more on the mechanism of resistance in AML patients clinically treated with venetoclax-based therapies. His work discovered that monocytic subclones driven by oncogenic mutations such as RAS mutants switched their anti-apoptotic dependence from BCL2 to MCL1, became intrinsically resistant to venetoclax, therefore promoted relapse/refractory response in venetoclax plus azacitidine-treated AML patients. Most recently, during his new role as a PI at Liangzhu Laboratory, he further revealed the stem cell origin of venetoclax resistance, demonstrating that a novel type of monocytic LSCs, distinct from the more conventional CD34+ primitive LSCs, is the source of monocytic relapse upon venetoclax-based therapies. The work also revealed that the newly identified monocytic LSCs are exclusively sensitive to chemotherapy agent Cladribine, setting the foundation for combining Cladribine-containing chemotherapy regimens with Venetoclax for a better treatment of AML.
Focusing on AML biology and therapeutic discovery, Dr. Pei has published more than 25 papers in Cancer Discovery, Cell Stem Cell, and other leading journals, and received more than 4100 citations. The latest work from Dr. Pei’s group discovered the stem cell origin of venetoclax resistance, and also revealed the critical mechanisms underlying venetoclax/cladribine combination therapies for treating human AML (Cancer Discovery 2020; 2023). His work has won the AACR Best Article Series Award, the ASH Abstract Achievement Award, and the National Excellent Youth Award (abroad series) from China.
