The NOD/SCID Xenograft Model Provides Clinically-Relevant Insights into Glucocorticoid-Induced Gene Expression in Childhood B-Cell Precursor Acute Lymphoblastic Leukemia

ABSTRACT: Introduction. Glucocorticoids are critical drugs used to treat acute lymphoblastic leukemia, and response to glucocorticoids is highly predictive of outcome. Here we report a study evaluating the NOD/SCID xenograft mouse model to investigate glucocorticoid-induced gene expression. Methods. NOD/SCID mice were inoculated with ALL-3, a glucocorticoid-sensitive xenograft, and when highly engrafted were randomised to either dexamethasone 15mg/kg or vehicle control IP. Cells were harvested at 0, 8, 24 or 48 hours thereafter, RNA was extracted and hybridised onto Illumina WG-6_V3 chips. Results. The 8 hour dexamethasone-treated timepoint had the highest number of significantly differentially expressed genes with minimal changes seen across the time-matched controls. Replicate analysis revealed th
