The Beattie Lab investigates the biological basis of motoneuron diseases with a focus on spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS).

Lab members are also interested in the genetic and molecular mechanisms that promote motoneuron development, such as the cues that guide motor axons to their target muscles and the formation of the connections between motoneurons and muscle. The lab has also recently started a project modeling glioblastoma to characterize the mechanism of tumor cell migration in the brain and to generate an animal model for efficient drug screening. Zebrafish is the vertebrate model organism used in this lab, due to their well-characterized nervous system and relatively simple neuromuscular organization. Moreover, by modeling diseases in zebrafish, researchers in the Beattie Lab are able to develop new approaches, such as genetic and drug screens, to identify targets that may alleviate the disease process.

Biological basis of the motoneuron disease Spinal Muscular Atrophy (SMA) and ALS

Members of the Beattie lab have had a long-standing interest in the motoneuron disease Spinal Muscular Atrophy (SMA), a motoneuron degenerative disease caused by mutations in the survival motoneuron gene (SMN) that result in low levels of the SMN protein. Although the ubiquitously expressed, SMN protein has been implicated in the snRNP (RNA and protein) complex essential for mRNA splicing, it remains unclear why low SMN levels compromise motoneurons. Using protein knockdown technology (anti-sense morpholinos), the Beattie lab has decreased the amount of SMN present during zebrafish development and found dramatic defects in motor axon outgrowth and guidance. In particular, motor axons were truncated and excessively branched. Lab members have gone on to generate maternal:zygotic (mz) SMN mutants and show the defects in motor axon outgrowth are due to poor motoneuron development. Using a conditional transgene on the mutant background, they showed that SMN protein is needed very early in motoneuron development.

Now, they’re focused on understanding how SMN functions in motoneuron development and how this affects motor circuit formation. In particular they are focusing on the interaction between SMN and RNA binding proteins (eg HuD, Zbp1, Zbp2) that facilitate motoneuron development by stabilizing and/or localizing RNAs in growing axons and dendrites.

Amyotrophic lateral sclerosis is an adult onset, fatal motoneuron degenerative disease that has no cure and limited therapies. The lab has generated a genetic model of ALS that reveals hallmarks of the disease including motoneuron loss and letality. Their goal is to understand the early changes in the spinal cord of these animals as a way to better understanding the mechanism of motoneuron dysfunction in ALS.

Using zebrafish to study brain cancer

Glioblastoma (GBM) is a deadly brain cancer with few effective drug treatments available. To facilitate analysis of glioblastoma tumor cell behavior in real time and to develop new approaches for GBM drug screens, the Beattie Lab has generated and standardized a xenotransplant model of GBM in zebrafish. Using this standardized approach, they have transplanted two patient-derived GBM cell lines, serum grown adherent cells (X12) and neurospheres (GBM9) into the midbrain region of embryonic zebrafish. Analysis of larvae over time showed progressive brain tumor growth and premature death with both cell lines, however, fewer GBM9 cells were needed to cause tumor growth and lethality. Approximately half of the cells in both xenotransplants were dividing whereas control mouse neural stem cells failed to engraft and were cleared from the brain. GBM9 cells differentiated over time in vivo, whereas X12 differentiated very early suggesting that these tumors were less dynamic in vivo. Both cell types generated tumors that contained Sox2-positive cells indicative of neural stem cells. To determine whether GBM9 tumors were responsive to currently used therapeutics, they treated transplanted larvae with either temozolomide or bortezomib and found a reduction in tumor volume in-vivo and an increase in survival supporting the use of this standardized model for drug screening. The lab is now focused on understanding what types of tumor cells survive drug treatment and whether these cells can generate new tumors. Moreover, in collaboration with colleagues on campus, they are testing novel drug compounds for efficacy against GBM using this new model.
