Acute myeloid leukemia discovery tackles drug-resistant gene mutations
Researchers from the Kapur lab and their collaborators unveiled insights expected to enhance treatment options for acute myeloid leukemia (AML). With a new chemical compound engineered to overcome drug-resistant gene mutations not targeted by current treatments, the researchers aim to provide a new alternative with longer-lasting effects and improve outcomes for future patients battling this aggressive disease.

New gene therapy approach shows promise for Duchenne muscular dystrophy
Researchers in our gene and cell therapy program have made a significant breakthrough in developing a new gene therapy approach that restores full-length dystrophin protein, which could lead to new treatments for people with Duchenne muscular dystrophy. In a recent study published in Nature Communications led by Renzhi Han, PhD, the team demonstrated the effectiveness of this novel gene therapy technology in improving muscle tissue and overall strength in mice models of Duchenne muscular dystrophy.

New research explores the urea cycle’s strong connection to fatty liver disease
Brian DeBosch, MD, PhD, joined us in July 2024 to lead the Wells Center’s newly established nutrition and molecular metabolism research program. DeBosch is making strides in understanding the molecular origins of fatty liver disease, a leading cause of liver failure in the United States. In a study recently published in Cell Metabolism, DeBosch and his research collaborators uncovered a critical link between defects in the urea cycle and the development of fatty liver disease.
