Project description:TFE3 is a bHLH-ZIP transcription factor, which nuclear localization is regulated by a tumor suppressor FLCN. In order to analyze TFE3 occupancy in whole genome, we have generated and utilized a HK-2 HA-TFE3-inducible cell line which express HA-tagged TFE3 in a doxycycline-dependent manner. HA-TFE3 bound regions were determined by ChIPSeq.
Project description:PRCC-TFE3 is an oncogenic chimeric transcription factor derived from human TFE3-rearranged renal cell carcinoma. To analyze its genome-wide occupancy, we developed HA-tagged PRCC-TFE3-inducible HK-2 cell lines, which expresses HA-tagged TFE3 in a doxycycline-dependent manner. We determined the binding regions of HA-PRCC-TFE3 by ChIPSeq.
Project description:PRCC-TFE3 is an oncogenic chimeric transcription factor identified in human TFE3-rearranged renal cell carcinoma. To analyze gene expression changes driven by PRCC-TFE3, we generated and utilized an HA-tagged PRCC-TFE3-inducible HK-2 cell line, which expresses HA-tagged PRCC-TFE3 in a doxycycline-dependent manner. Cells were cultured with or without doxycycline, and comprehensive gene expression analysis was conducted using RNA-seq.

Project description:The bHLH transcription factor Tfe3 is a powerful regulator of pluripotency and we report a genome-wide analysis of Tfe3 occupancy in mouse ES cells. Nuclear localization of Tfe3 is inhibited by a protein complex containing the tumor-suppressor Folliculin (Flcn) and we also determine Tfe3 binding sites in ES cells expressing an shRNA targeting Flcn. Specificity is controlled for by using unspecific IgGs and ES cells expressing an shRNA targeting Tfe3. ChIP-Seq profiling of Tfe3 in ES cells

Project description:PRCC-TFE3 is an oncogenic chimeric transcription factor identified in human TFE3-rearranged renal cell carcinoma. To investigate the function of PRCC-TFE3 in vivo, we generated PRCC-TFE3 knock-in (KI) mice by inserting a loxP-STOP-loxP-PRCC-TFE3 cassette into the Rosa26 locus. When PRCC-TFE3 KI mice were crossed with Cadherin 16-Cre transgenic mice (KSP-Cre), the resulting mice developed TFE3-RCC in the kidney. Our findings revealed that hypoxia-inducible factors HIF1α and HIF2α are directly upregulated by PRCC-TFE3. To clarify the roles of HIF1α and HIF2α in TFE3-RCC development, we further crossed PRCC-TFE3 KI mice with HIF1α flox and/or HIF2α flox mice.
