Project description:We report the genome wide RNA sequencing for high-throughput profiling of FOXQ1 target genes in melanoma and carcinoma cells. We generated melanoma (SK-Mel-147) and ovarian carcinoma cells (SCOV3) ectopically expressing FOXQ1. We find that FOXQ1 differentially regulates the expression of several genes in melanoma cells as compared to carcinoma cells. Specifically, FOXQ1 induces the expression of several genes in ovarian carcinoma cells SCOV3 and suppresses the expression of the same genes in melanom cells. We show that this differentialy regulation of the same target gene depends upon the nuclear levels of beta-catenin. High levels of active nuclear beta-catenin promote FOXQ1 mediated transcriptional activation of genes whereas low levels contribute to TLE/Groucho- mediated repression. This study provides a framework for understanding the lineage specific pattern of transcriptional regulation by FOXQ1 and its contextual determinants.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:RNA-seq was performed to identify novel mechanistic targets of FoxQ1 in human breast cancer cells using empty vector-transfected control (EV) and FoxQ1 overexpressing SUM159 cells. We found that interleukin-1α and interleukin-8 are direct transcriptional targets of FoxQ1.
