About the Nichols Lab

Germline genetic variants can increase the risk for cancer and certain immune disorders. Our laboratory is interested in identifying what those variants are and how they contribute to disease. We focus on understanding how specific germline genetic changes impact blood cell development and function. This work will allow us to explore new diagnostic and treatment approaches for pediatric patient populations.

Our research summary

At the heart of our laboratory’s research program is the aim to better understand how germline genetic variants can lead to cancer and particular hyperinflammatory disorders. Armed with this more in-depth knowledge, our work will inform more effective treatments for children who are at a greater risk for developing cancer and hyperinflammation.

Cancer predisposition: discovery efforts

Broadly speaking, our research focuses on defining the prevalence and spectrum of germline genetic variants that predispose to childhood cancer and understanding how these variants impact clinical presentation, tumor biology, treatment response and overall outcome.  We use a variety of complementary approaches to mine the genomes of cancer prone kindreds and large cohorts of children with cancer. Through this work, we aim to gain a better understanding of the underlying disease mechanisms and then use this information to improve the diagnosis and management of children and families at increased genetic risk for cancer.

Analysis of ETV6-mediated predisposition in childhood ALL

Through the efforts described above, we identified that germline variants in ETV6, the gene encoding an essential hematopoietic transcription factor, are associated with predisposition to thrombocytopenia and B-acute lymphoblastic leukemia (B-ALL). We are currently working to better understand how germline variants in ETV6 impact the transcriptional landscape of hematopoietic stem and progenitor cells and B lymphoid progenitors to promote leukemia formation. We have generated experimental mouse models and iPSC systems with targeted mutations to interrogate the function and impact of several identified ETV6 variants. With this knowledge, we aim to better understand the role of ETV6 in B-leukemogenesis and to use this information to develop novel approaches to treat or even prevent ETV6-related leukemia.

Pathogenesis of hyperinflammation

Hemophagocytic lymphohistiocytosis (HLH) is a rare and often fatal hyperinflammatory syndrome characterized by the dysregulated activation of cytotoxic T cells and macrophages which secrete high levels of pro-inflammatory cytokines. Our laboratory uses patient samples and animal models to decipher the cellular and molecular mechanisms underlying development of HLH. The “cytokine storm” associated with HLH is also found in other hyperinflammatory scenarios as with COVID-19 and response to CAR T-cell therapy. Using HLH as a model disease will inform treatment of cytokine storm syndromes more broadly, St. Jude is now leading a multi-institution clinical trial for HLH based on research conducted in our laboratory.

About Kim E. Nichols

Dr. Kim Nichols earned her BS in Biology from Dartmouth College and MD from Duke University School of Medicine. She completed a fellowship in pediatric oncology at the Dana-Farber Cancer Institute as well as a postdoctoral fellowship in molecular genetics at Massachusetts General Hospital. A member of the St. Jude faculty  and Department of Oncology since 2014, Dr. Nichols serves as the Director of the Division of Cancer Predisposition, which aims to enhance clinical care, research, and education surrounding hereditary forms of childhood cancer. Her research program focuses on identifying and characterizing germline genetic variants and understanding how they increase the risk for cancer and certain immune disorders.
