Research Abstract:

Using NF1 as a genetic model system to understand growth and differentiation in the normal brain, the Gutmann laboratory aims to characterize the genomic, genetic, cellular, and molecular factors that contribute to the development of nervous system tumors (gliomas and neurofibromas), brain development and behavioral deficits.

Defining these contributing factors represents the first step toward establishing new treatments for children and adults with NF1. Moreover, NF1 provides unique opportunities to unravel the complexities of related medical problems in the general population, including adult and childhood brain tumors, nerve tumors, sarcoma and autism.

We employ these single gene disorders as model genetic platforms to understand how genomic, tissue, cellular and molecular factors control normal neural stem cell, neuron and glial (microglia and macroglia) function in vitro and in vivo. To accomplish these goals, we have generated numerous genetically-engineered mouse models and human induced pluripotent stem cell lines.

Current research in our laboratory includes:

• The impact of Ras signaling, mammalian target of rapamycin (mTOR) activity, and intracellular cyclic AMP generation in specifying cell proliferation, cell death, and differentiation in the brain

• The instructive role of the tumor microenvironment, specifically microglia (macrophage-like cells), in dictating brain tumor formation and growth

• The diversity of neural stem cell function as defined by the brain region of origin relevant to normal brain development and tumorigenesis in children

• The molecular and genomic determinants that underlie disease heterogeneity (precision medicine)

• Sexually-dimorphic phenotypes in neurons and microglia
