Project description:SOX2 is not expressed in normal human epidermis but its expression is elevated in pre-neoplastic epidermis suggesting that it may have a role in the tumorigenesis process. The goal of this study is to determine the impacts of SOX2 overexpression in regenerated human epidermis. Global gene expression profiling using U133 plus 2.0 arrays were used to deteremine the genes perturbed by overexpression of SOX2.

Project description:Transcriptional profiling of SOX11-expressing mouse epidermis (K14-rtTA;TRE-Sox11-FLAG) compared to control (K14-rtTA) epidermis at postnatal day 4 (P4). The littermate pairs were injected with Dox for 12 h before their epidermis was harvested. Goal was to identify the gene expression profile of postnatal epidermis changed by SOX11 induced expression.

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.

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.

Project description:Sox2 has been studied in several types of human solid tumors. The investigators found that Sox2 had higher expression level in colorectal cancer and metastatic tissues than normal tissues. So the investigators assumed that whether Sox2 plays an important role in the progression and migration of colon cancer.

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:Squamous cell carcinoma (SCC) of lung is a devastating malignancy with no effective treatments, due to its complex genomic profile. Therefore, pre-clinical models mimicking its salient features are urgently needed. Here we describe mouse models bearing various combinations of genetic lesions predominantly found in human SCC. We show that Sox2 but not Fgfr1 overexpression in tracheobronchial basal cells combined with Cdkn2ab and Pten loss results in SCC closely resembling the human counterpart. Interestingly, Sox2;Pten;Cdkn2ab mice develop SCC with a more peripheral location when Club or Alveolar type 2 (AT2) cells are targeted. Our model highlights the essential role of Sox2 in promoting a squamous cell fate from different cells-of-origin and represents an invaluable tool for the developing better intervention strategies.

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).
