Title Alveolar Soft Part Sarcoma is driven by ASPSCR1::TFE3-dependent and therapeutically targetable transcriptional programs [RNA-Seq]
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Summary Alveolar soft part sarcoma (ASPS) is a rare mesenchymal malignancy driven by the ASPSCR1::TFE3 fusion, though the mechanisms by which this oncogenic transcriptional regulator drives cancer growth are poorly understood. Here, we characterize the transcriptional and chromatin landscapes of ASPS tumors and preclinical models, identifying the essential role of ASPSCR1::TFE3 in tumor cell viability by regulating core transcriptional programs including cell proliferation, angiogenesis, and mitochondrial biology. ASPSCR1::TFE3 directly interacts with key epigenetic regulators at enhancers and promoters to support ASPS-associated transcription. Among the effector programs driven by ASPSCR1::TFE3, cell proliferation was driven by high levels of Cyclin D1 expression, and disruption of Cyclin D1/CDK4 signaling led to loss of ASPS proliferative capacity, which when combined with angiogenesis inhibition halted tumor growth in xenografts. These results define the ASPS oncogenic program, mechanisms by which ASPSCR1::TFE3 controls tumor biology, and identify a strategy for therapeutically targeting tumor cell-intrinsic vulnerabilities.
Overall design To investigate the transcriptional programs in ASPS, we generated RNA-seq samples from tumors and preclinical models. RNA-seq was performed on cell cultures and xenografts following treatment with palbociclib.
