ETS1 Orchestrates a Hybrid EMT Program Driving in vivo Metastasis and Immune Evasion

Listed in NCBI GEO

Transcriptional Intratumoral heterogeneity (ITH) is a hallmark of aggressive cancers, yet how transcriptional ITH programs drive tumor metastasis and immune evasion in upper aerodigestive squamous cell carcinoma (UASCC) remains unclear.

Description

Through single-cell RNA sequencing analysis of UASCC cells and patient tumors, we uncovered a hybrid EMT (hEMT) ITH program linked to metastatic dissemination. The transcription factor ETS1 was identified as a master regulator of hEMT program, directly activating pro-metastatic genes and promoting distant spread in vivo.

Unexpectedly, ETS1 also orchestrated an immune-cold tumor microenvironment by transcriptionally activating the STAT1-PDL1 axis, suppressing T lymphocyte infiltration and elevating immune checkpoint molecules. Clinically, ETS1-high tumors strongly correlated with poor survival and resistance to immune checkpoint blockade across multiple cohorts. Leveraging drug screens, we discovered that ETS1-high cancers are vulnerable to HSP90 inhibitors (e.g., Alvespimycin), which suppress ETS1 by disrupting HIF1A-mediated transcriptional activation.

Together, our work reveals ETS1 as a dual driver of tumor distal metastasis and immune evasion in UASCC, while nominating HSP90 inhibition as a tailored strategy for ETS1-driven tumors. These findings provide a roadmap for targeting aggressive ITH subsets and overcoming immunotherapy resistance.
