Further investigations led O'Malley to identify a crucial function of the SRC-3 coactivator in immune T-regulatory cells, which play a protective role against autoimmunity but can also suppress the immune system's ability to kill cancer cells.[18] His team developed a mouse model with the SRC-3 gene specifically deleted in T-regulatory cells, finding that this modification allowed T-conventional attack cells to effectively eliminate tumors.[19] His lab's breakthrough demonstrated that these genetically modified animals exhibited a remarkable resistance to major cancers throughout their lifespan. O'Malley's group went on to pioneer a coactivator-centric adoptive cell transfer technique aimed at cancer treatment, showing that a single injection of SRC-3-deleted T-regulatory cells could permanently eliminate existing cancers without detectable toxicity.[20] This method has been patented and will be developed by CoRegen-BCM for clinical application.[21]
Until his death, O'Malley led the Baylor Center for Coregulator Research, along with Drs. David Lonard, Sang-Jun Han, and Clifford Dacso. His contributions to the field of Endocrinology earned him recognition as the Father of Molecular Endocrinology.[4]
He was an elected member of the National Academies: of Sciences, of Medicine, and of Inventors. O'Malley received over 65 honors and major awards, including the National Medal of Science in 2008. Throughout his career, he mentored more than 220 scientists, published over 750 papers, and held 33 patents related to gene regulation, molecular endocrinology, steroid receptor-coactivator action, and molecular and cell-based medical therapies.
Death
O'Malley's death at the age of 88 was announced on November 11, 2025.[22]
