Title Hyperactive STAT5 Hijacks T-Cell Receptor Signaling and Drives Immature T-Cell Acute Lymphoblastic Leukemia
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive immature T-cell cancer.
Mutations in IL7RA were analyzed genetically, but downstream effector functions such as
STAT5A/B hyperactivation are poorly understood. Here, we studied the most frequent and
clinically challenging STAT5BN642H driver in T-cell development and immature T-cell cancer
onset and compared it to STAT5A hyperactive variants in transgenic mice. Enhanced STAT5
activity caused disrupted T-cell development and promoted an early T-cell progenitor (ETP)-
ALL phenotype with upregulation of genes involved in T-cell receptor (TCR) signaling, even in
absence of surface TCR. Importantly, TCR pathway genes were overexpressed in human T-
ALL and mature T-cell cancers and activation of TCR pathway kinases was STAT5-dependent.
We confirmed STAT5-binding to these genes using ChIP-seq analysis in human T-ALL cells,
which were sensitive to pharmacologic inhibition by dual STAT3/5 degraders or ZAP70
tyrosine kinase blockers in vitro and in vivo. We provide first genetic and biochemical proof
that STAT5A and STAT5B hyperactivation can initiate T-ALL through TCR pathway hijacking
and suggest similar mechanisms for other T-cell cancers. Thus, STAT5 or TCR component
blockade are targeted therapy options, particularly in patients with chemo-resistant clones
carrying STAT5BN642H.
