About CRI

Children’s Medical Center Research Institute at UT Southwestern (CRI) is a nonprofit research institute built on the clinical expertise of Children’s Medical Center Dallas and the scientific excellence of UT Southwestern Medical Center. Under the leadership of Sean J. Morrison, Ph.D., CRI has created a world-class research and training environment that is collaborative and inclusive.

We are located in the heart of Dallas, Texas, and are home to an interdisciplinary group of scientists and physicians from all over the world. Our research is focused at the intersection of stem cells, cancer, and metabolism because we believe these areas hold uncommon opportunity for discoveries that are changing the way we think about important scientific questions and yielding new strategies for treating disease.

Mission

CRI is improving our understanding of the biological basis of disease by focusing at the interface of stem cells, cancer, and metabolism.

Our ultimate goals are to:

Research Areas

Research requires commitment, vision, and a relentless determination to push the boundaries of knowledge. Our scientists and physicians are working in the fields of stem cells, cancer, and metabolism.

Genetic and Metabolic Disease Program

CRI researchers study the ways in which perturbations in metabolism contribute to diseases such as cancer and to conditions such as inborn errors of metabolism. Inborn errors of metabolism occur when children are born with genetic defects that impair the function of metabolic pathways. CRI established the Genetic and Metabolic Disease Program (GMDP) to integrate patient care and research to advance the diagnosis and treatment of genetically determined metabolic diseases.

Tissue Regeneration Program

Researchers in CRI’s Tissue Regeneration Program are identifying the cellular and genetic basis of tissue healing in a wide range of organs. Elucidation of these mechanisms will advance our ability to repair tissues damaged by age, disease, and trauma.

Cancer Biology

Cancer is a complex group of diseases characterized by rapid and uncontrolled cell proliferation and metastasis to other parts of the body. CRI researchers use a variety of approaches to identify the mechanisms that drive the formation and progression of several cancers in order to find new treatments.

Garcia-Bermudez Lab uncovers unique pathway tumors use to acquire antioxidant lipids

Garcia-Bermduez Lab: Tumors can tap a nontraditional pathway to acquire lipoproteins to enrich cancer cells with an antioxidant shield and survive stress: special sugar-coated structures on the cell surface called sulfated glycosaminoglycans (GAGs). Lipoproteins transport the majority of lipids in blood, including α-tocopherol – a form of vitamin E. While α-tocopherol is an antioxidant that can nourish healthy tissues, scientists found this potent antioxidant shield is used by cancer cells to resist ferroptosis, a type of cell death triggered by toxic lipid by-product buildup.

DeBerardinis Lab finds high glucose contribution to tricarboxylic acid cycle involved in predicting cancer spread

DeBerardinis Lab: In localized non-small cell lung cancer (NSCLC), a tumor’s ability to use carbon from glucose to feed the tricarboxylic acid (TCA) cycle predicts cancer spread beyond the lung, months to years before metastases are clinically apparent. Cancer Discovery 15, 702-16

CRI scientists link hematopoietic cell transplant deaths to beta-blocker use

Morrison Lab: Previous Morrison Lab research discovered β2- and β3-adrenergic receptor signaling are needed for hematopoietic stem cells to regenerate after chemo or radiation therapy. CRI scientists discovered patients are at increased risk of death if they take certain previously prescribed beta-blockers in the weeks after an allogeneic hematopoietic cell transplant. Non-selective beta-blockers impaired hematopoietic regeneration, but b1-selective inhibitors did not. Cancer Discovery 15, 748-66

Morrison Lab discovers ancient viral DNA activates blood cell production during pregnancy, after bleeding

Morrison Lab: Scientists discovered retrotransposons are activated during pregnancy and after significant bleeding in blood-forming stem cells to increase blood cell production. This is an important step toward defining the purpose of “junk DNA” in humans. Retrotransposon expression promotes stem cell division by activating the immune sensors, cGAS and STING, which induce an interferon response to stimulate blood cell production. Science 386:eado6836
