Expertise

Dr. Hogarty has clinical expertise managing patients with neuroblastoma, germ cell tumors (malignant and benign), and histiocytic diseases of childhood (LCH and HLH). He holds international leadership roles in neuroblastoma clinical and translational research through the Children's Oncology Group (COG), Advances in Neuroblastoma Research Association (ANRA), International Neuroblastoma Research Group (INRG) and the New Approaches to Neuroblastoma Therapy Consortium (NANT). He also participates in the International Histiocyte Society and is a co-investigator and site PI for the North America Consortium for Histiocytosis.

The Hogarty Lab studies the childhood solid tumor neuroblastoma with the goal of identifying principal oncogenic pathways for the development of novel therapeutics.

Keywords: pediatric cancer, neuroblastoma, MYC, Bcl2 signaling, cancer therapy resistance, polyamines

There are currently three main projects within the lab focused on (1) the contributions of polyamines to neuroblastoma pathogenesis; (2) the role Bcl2 family proteins and mitochondria play in defining stress sensitivity and resistance patterns; and (3) the role chromatin remodeling BAF complexes (Swi/Snf) play in tumor pathogenesis.

Current polyamine-related efforts utilize targeted inhibitors of polyamine metabolism to credential polyamine homeostasis as an essential signaling module downstream of MYC in oncogenesis. We use complementary preclinical models (human xenografts and transgenic mouse models) to define the extent of cancer cell intrinsic (protein stress) and extrinsic (altered tumor immunoenvironment) activities.

Our Bcl2 functional profiling studies have led to the recognition of heterogeneity in major survival dependencies for neuroblastoma that appear hardwired in tumors. We are exploring biomarkers of Bcl2 dependence to triage Bcl2 inhibitors for this subset, and using Mcl1-dependent tumors for functional screening to identify novel Mcl1 antagonists. Importantly, we have identified a mitochondrial phenotype for multidrug resistance using this platform.

Finally, we identified mutations in ARID1A and ARID1B in highest risk lethal neuroblastomas. These BAF complex members are proposed to alter neural differentiation programs through effects on chromatin remodeling and we are characterizing BAF membership and activities to define principal mechanisms.
