Project description:RPF-1, a transcription factors encoded by POU6F2 gene, appears to be expressed in the developing nervous system and embryonic kidney. We generated a stable HEK/RPF-1 transfectant expressing the protein in a tetracycline (Tet)-dependent induction and addressed the whole transcriptome regulated by RPF-1. We detected a gross alteration of gene expression that is consistent with its occupancy at proximal promoters, and gel retardation assay and promoter-reporter activity, addressing a few target genes, indicated a dependence by RPF-1 of transcriptional response. GO analysis supports a role for this factor in the genetic programs guiding early differentiation of embryonic kidney and neuronal fate.

Gene array analysis shows that RPF-1 transcription factor modify the transcriptome of HEK293 cells by regulating a genetic program endowed with developmental programs Comparison of HEK293 cells induced for RPF-1 expression (Tet-) over uninduced control (Tet+) and Mock cells. RPF-1 cDNA was inserted into the pTRE2puro vector to generate stable Tet-inducible KEK293 transfectants. Upon Tet removal from the medium, HEK/RPF-1 transfectants expressed the transcription factor RPF-1. Cells were then seeded in 10 cm dishes, cultured for 48 h either in complete medium supplemented with Tet (+) or in Tet-depleted medium (-), harvested, and spun down before RNA isolation. Comparative analysis between HEK/RPF-1 induced (Tet-) and uninduced (Tet+) transfectants allowed us to identify genes transcriptionally regulated by RPF-1. Residual effects on gene expression due to Tet supplementation into culture media was ruled out by comparison with the Mock transfectant.

Project description:HEK293 cells were transfected with control plasmid (pcDNA1/Neo; Invitrogen) or with the plasmid encoding HCaRG by a standard calcium phosphate co-precipitation method. The clones expressing the highest levels of HCaRG, HCaRG clone 8 and 9 were used in this experiment, while clone transfected with vector alone, Neo clone, served as controls. Stable transfectants were synchronized and grown in the presence of 10% FBS for 48 h. Total RNAs were purified with the mini RNeasy kit (Qiagen).

Project description:Identification of genes regulated by the transcription factor HNF4a2 Experiment Overall Design: We used microarrays to identify genes regulated by the transcription factor HNF4a2. HEK293 cell lines containing doxycyclin-inducible wilt type or mutant forms of HNF4a2m which were introduced by FRT/FLP mediated recombination into FLP-In T-REx 293 cells (Invitrogen) were treated for 24 hours with 1 µg/ml doxycyclin. Gene expression profiles of induced and noninduced cells were compared to identify HNF4 regulated targets.

Project description:A current model for the genomic recruitment of Kap1 is via its interaction with KRAB domain-containing zinc finger transcription factors. We have performed ChIP-seq for various mutant KAP1 proteins and shown that this recruitment mechanism mediates binding of KAP1 only to the 3M-CM-"M-BM-^@M-BM-^Y ends of zinc finger genes and that other factors are involved in recruiting KAP1 to promoter regions. 17 total ChIP-seq datasets; three different FLAG-KAP1 mutants, one FLAG-KAP1 wild type, and four different Input datasets from 4 different stable cell lines derived from HEK293 cells: 1 FLAG-KAP1 wild type dataset and 1 Input dataset done from HEK293 stable cells; 1 FLAG-KAP1 HP1BDmut dataset and 1 Input dataset done from HEK293 stable cells, 1 FLAG-KAP1 N-ter RBCC{delta}mut dataset and 1 Input dataset done from HEK293 stable cells, 1 FLAG-KAP1 C-ter PB{delta}mut dataset and 1 Input dataset done from HEK293 stable cells. One FLAG-KAP1 N/C-ter (RBCC+PB){delta}mut dataset done from T-REx HEK293 stable cells. One endogenous KAP1 dataset done from HEK293 cells. Two independent ELK4 datasets done from duplicate HEK293 cells. One endogenous Kap1 dataset and one Input dataset from a stable cell line derived from U2OS cells.
