Nature 380, 711-4.)] Embryonic pancreases from homozygous mutants and their wild-type littermates were harvested. Total RNA was isolated amplified using a linear amplification kit and used to prepare the hybridization samples through indirect labeling.

Project description:Sox4 is a transcription factor expressed during embryonic development and some adult tissues such as lymphoid organs, pancreas, intestine and skin. During embryogenesis, Sox4 regulates the survival of mesenchymal and neural progenitors, lymphocyte and myeloid differentiation, and pancreatic, bone and cardiac development. Aberrantly increased Sox4 expression is linked to malignant transformation and metastasis in several types of human cancer. To study the role of Sox4 in the adult organism, we first generated mice with reduced whole-body Sox4 expression. These mice display a plethora of age-related degenerative disorders and reduced spontaneous cancer incidence, indicating a role for this protein in maintaining adult tissue homeostasis and in tumor growth. To specifically address a role for Sox4 in adult stem cells, we conditionally deleted Sox4 (Sox4cKO) in stratified epithelia. Sox4cKO mice show increased skin stem cell quiescence and DNA damage accumulation, accompanied by resistance to chemical carcinogenesis. These phenotypes correlate with downregulation of cell cycle, DNA repair and skin stem cell genes in the absence of Sox4. Altogether, these findings highlight the importance of Sox4 in adult tissue homeostasis and cancer. Sox4 WT and cKO (conditional KO in skin) skin was collected for microarray hybridization, to study the contribution of Sox4 to skin homeostasis in basal conditions (Telogen)

Project description:We knocked down SOX4 in T24 cell and created 3 cell lines: T24-scrambled, T24-SOX4-knockdown and T24-SOX4-rescue and compared gene expression changes SOX4 is a developmental transcription factor that is overexpressed in as many as 23% of bladder cancer patients, but the role of SOX4 in bladder cancer tumorigenesis is not well understood. Given SOX4’s many roles in embryonic development and context-dependent regulation of gene expression, we sought to understand SOX4’s contribution to bladder cancer and to elucidate SOX4 regulated genes that might contribute to tumorigenesis. We employed a CRISPR interference (CRISPRi) method to transcriptionally repress SOX4 expression in T24 bladder cancer cell lines, rescued these cell lines with lentivirally expressed SOX4, and performed whole genome expression profiling. SOX4 knockdown cells exhibited decreased invasive capabilities but no changes in migration or proliferation, while rescue with SOX4 lentiviral vector restored the invasive phenotype. Gene expression profiling revealed 173 high confidence SOX4 regulated genes

Project description:SOX4 is a critical developmental transcription factor in vertebrates and is required for precise differentiation and proliferation in multiple tissues. In addition, SOX4 is overexpressed in many human malignancies, but the precise role of SOX4 in cancer progression is not well understood. Here we have either eliminated SOX4 using siRNA or overexpressed a SOX4 cDNA and compared the gene expression patterns against control GFP transfections to identify SOX4 target genes. Data described in manuscript P. Liu et al., Cancer Res 46, 4011 (April 15, 2006) Experiment Overall Design: LNCaP prostate cancer cells were transfected with either a SOX4 cDNA, a pool of SOX4 siRNAs or a control GFP expression vector. Each transfection was performed in duplicate on two separate days. Total RNA was harvested 24 hours post-transfection

Project description:The SOX4 gene belongs to a family of transcription factors and we previously unveiled SOX4 gene amplification and over-expression in a subset of lung cancers, indicating it may constitute a driver oncogene. Here, we searched for SOX4 transcriptional targets and investigate their involvement in lung development and carcinogenesis. We abrogated SOX4 expression in the NIH-H522 lung cancer cell line, carrying SOX4 amplification and over-expression, using an inducible short-hairpin system. Global analysis of gene expression identified about 90 genes down-regulated after SOX4 abrogation many of them related to neural development. We also demonstrated recruitment of SOX4 to many of these promoters, evidencing their nature as direct transcriptional targets of SOX4. Most of these transcripts were significantly increased in lung cancer cells with ectopic SOX4 over-expression and in lung tumors with high levels of SOX4. Conversely, many of them exhibited significant low expression levels in embryonic fibroblasts from Sox4-/- mice. We generated H522-derived cells that down-regulate SOX4 in an inducible manner. The H522 cells were transfected with a tetracycline (tet) repressor expression construct and a tet-repressor-controlled expression vector (tet-on) containing a shSOX4. An stable clone, H522Tr-shSOX4-1, which down-regulate SOX4 expression by 90%, 48 hours after adding doxycycline, was chosen for further analysis. To determine the gene expression profile characteristic of SOX4 depleted expression we compared the global gene expression of the parental H522 cells to the H522Tr-shSOX4-1 cells at 0, 24 and 96 hrs after inducing the shSOX4 with doxycycline using the Whole Human Genome Microarray from Agilent.
