SATB2 induces transcriptional programs in melanoma that lead to metastatic behavior [ChIP-Seq]

UID: 10778

Description
Summary from the GEO: "We report the distribution of human SATB2 in a primary zebrafish melanoma that overexpresses human SATB2, and H3K27Ac histone marks in zebrafish melanomas overexpressing either EGFP (control) or human SATB2."

Overall design from the GEO: "Examining SATB2 bound regions, and H3K27Ac-bound (super) enhancers in zebrafish melanomas."

Abstract summary: "Recent genomic and scRNA-seq analyses of melanoma demonstrated a lack of recurrent genetic drivers of metastasis, while identifying common transcriptional states correlating with invasion or drug resistance. To test whether transcriptional adaptation can drive melanoma progression, we made use of a zebrafish mitfa:BRAFV600E;tp53-/-model, in which malignant progression is characterized by minimal genetic evolution. We undertook an overexpression-screen of 80 epigenetic/transcriptional regulators and found neural crest-mesenchyme developmental regulator SATB2 to accelerate aggressive melanoma development. Its overexpression induces invadopodia formation and invasion in zebrafish tumors and human melanoma cell lines. SATB2 binds and activates neural crest-regulators, including pdgfab and snai2. The transcriptional program induced by SATB2 overlaps with known MITFlowAXLhigh and AQP1+NGFR1high drug-resistant states and functionally drives enhanced tumor propagation and resistance to Vemurafenib in vivo. In summary, we show that melanoma transcriptional rewiring by SATB2 to a neural crest mesenchyme-like program can drive invasion and drug resistance in autochthonous tumors."
