Project description:SOX2 is a transcription factor essential for pluripotent stem cells, and development and maintenance of squamous epithelium. We previously reported SOX2 an oncogene subject to highly recurrent genomic amplification in squamous cell carcinomas (SCCs). Here we demonstrate in SCCs that SOX2 interacts with another master squamous transcription factor p63, and through ChIP-seq show that genomic occupancy of SOX2 overlaps with that of p63 at a large number of loci and that they cooperatively regulate gene expression including ETV4, which we find essential for SOX2-amplified SCC cell survival. Furthermore, SOX2 binds to distinct genomic loci in SCCs than in embryonic stem cells and the SOX2-p63 coordinate binding is unique to SCC. In addition, a subset of SOX2 genomic binding sites in SCC that lack p63 co-occupancy are co-occupied by the AP-1 transcriptional complex. These demonstrate that SOX2’s actions in SCC differ substantially from its role in pluripotency and identify novel SOX2 interactions that will enable deeper characterization of SOX2’s function in SCC. SOX2 and p63 ChIP-seq from three lung and esophageal squamous carcinoma cell lines with amplification of SOX2 as well as SOX2 ChIP-seq from an ES cells.

Project description:SOX2 is a transcription factor essential for pluripotent stem cells, and development and maintenance of squamous epithelium. We previously reported SOX2 an oncogene subject to highly recurrent genomic amplification in squamous cell carcinomas (SCCs)1. Here we demonstrate in SCCs that SOX2 interacts with another master squamous transcription factor p63, and through ChIP-seq show that genomic occupancy of SOX2 overlaps with that of p63 at a large number of loci and that they cooperatively regulate gene expression including ETV4, which we find essential for SOX2-amplified SCC cell survival.

KYSE70 cells with stable expression of either pLKO-Tet-Op-shSOX2 or pLKO-Tet-Op-shTp63 were treated with 50ng/ml of doxycyline for 4 days. Total RNA was extracted, polyA+ selected, reverse transcribed, library constructed and sequencing was performed with Illumina HiSeq 2000. Differencial gene expression between the stable cell lines with Dox-induced and non-Dox treated was analyzed to determine the effects by suppression of either SOX2 or TP63 in KYSE70 cells.

Project description:Lineage-specific transcriptional regulators control differentiation states not only during normal development but also during cancer evolution. By investigating super-enhancer landscape of lung squamous cell carcinoma (LUSC), we identified a unique ‘neural’ subtype defined by Sox2 and a neural lineage factor Brn2. Robust protein-protein interaction and genomic co-occupancy of these factors indicated their transcriptional cooperation in this ‘neural’ LUSC in contrast to the cooperation of Sox2 and p63 in the classical LUSC. Introduction of p63 expression in the “neural’ LUSC invoked the classical LUSC lineage accompanied by Brn2 downregulation and increased activities of ErbB/Akt and MAPK-ERK pathways. Collectively, our data demonstrate a unique LUSC lineage featured by Sox2 cooperation with Brn2 instead of p63, for which distinct therapeutic approaches may be warranted.

Project description:We have identified SOX2 as a new oncogene and a likely driver of recurrent 3q26.3 amplifications in lung Squamous Cell Carcinoma. SOX2 is a crucial transcription factor implicated in Embryonic and Neural Stem Cells, that we found widely activatd in human lung SCC. This part of the study aimed at analyzing the transcriptomic consequences of SOX2 overexpression in a simple in vitro model (human lung squamous immortalized cells). Human lung squamous BEAS-2B cells were transduced for Control or SOX2 expression, and their transcriptomes compared using Affymetrix arrays.

Project description:While cell fate determination and maintenance are important in establishing and preserving tissue identity and function during development, aberrant cell fate transition leads to cancer cell heterogeneity and resistance to treatment. Here, we report an unexpected role for the transcription factor p63 (Trp63/TP63) in the fate choice of squamous versus neuroendocrine lineage in esophageal development and malignancy. Deletion of p63 results in extensive neuroendocrine differentiation in the developing mouse esophagus and esophageal progenitors derived from human embryonic stem cells. In human esophageal neuroendocrine carcinoma (eNEC) cells, p63 is transcriptionally silenced by EZH2-mediated H3K27 trimethylation (H3K27me3). Upregulation of the major p63 isoform ΔNp63α, through either ectopic expression or EZH2 inhibition, promotes squamous transdifferentiation of eNEC cells. Together these findings uncover p63 as a rheostat in coordinating the transition between squamous and neuroendocrine cell fates during esophageal development and tumor progression.
