Project description:To elucidate the mechanism of ETV5-mediated pre-B cell survival signaling, we investigated the gene expression pattern in BCR-ABL1-transformed ETV5+/+ and ETV5-/- B cell precursors. BCR-ABL1 transformed B cell precursors of ETV5wild-type and ETV5 knockout mice were subjected to RNA isolation

Project description:Alveolar type II (AT2) cell dysfunction contributes to a number of significant human pathologies including respiratory distress syndrome, lung adenocarcinoma, and debilitating fibrotic diseases, but the critical transcription factors that maintain AT2 cell identity are unknown. Here we show that the E26 transformation-specific (ETS) family transcription factor Etv5 is essential tomaintain AT2 cell identity. Deletion of Etv5 from AT2 cells produced gene and protein signatures characteristic of differentiated alveolar type I (AT1) cells. Consistent with a defect in the AT2 stem cell population, Etv5 deficiency markedly reduced recovery following bleomycin-induced lung injury. Lung tumorigenesis driven by mutant KrasG12D was also compromised by Etv5 deficiency. ERK activation downstream of Ras was found to stabilize Etv5 through inactivation of the cullin- RING ubiquitin ligase CRL4COP1/DET1 that targets Etv5 for proteasomal degradation. These findings identify Etv5 as a critical output of Ras signaling in AT2 cells, contributing to both lung homeostasis and tumor initiation.

Project description:Liver receptor homologue 1 (LRH-1) is an orphan nuclear receptor which has been implicated in the growth and development of breast, pancreatic and colorectal cancers (CRC). In order to identify novel LRH-1-regulated genes in CRC cells, we performed gene expression profiling following siRNA-mediated LRH-1 silencing in the CRC cell line HT29.

Project description:We hypothesized that ETV5 may be a mediator of the oncogenic effects of mutant FGFR3 in bladder cancer cells ETV5 was silenced by shRNA in the bladder cancer cell line 97-7 to investigate effect on phenotype. To identify downstream gene targets of ETV5 we compared gene expression profiles in silenced and control cells.

Project description:Insight into mechanisms controlling gene expression in the spermatogonial stem cell (SSC) will improve our understanding of the processes regulating spermatogenesis and aid in treating problems associated with male infertility. In this study we explored the global gene expression profiles of glial cell line-derived neurotrophic factor (GDNF) regulated transcription factors, Ets variant gene 5 (Etv5), B-cell CLL/lymphoma 6, member B (Bcl6b) and POU domain, class-3 transcription factor-1 (Pou3f1). We reasoned that these three factors may function as a core-set of transcription factors, regulating genes responsible for maintaining the SSC population. Using transient short-interfering RNA oligonucleotides (siRNA) to individually target Etv5, Bcl6b and Pou3f1 within mouse SSC cultures, we examined changes to the global gene expression profiles associated with these transcription factors. While there were only modest overlaps in the target genes regulated by the three factors, ETV5 was found to be a critical downstream regulator of GDNF signaling that mediated the expression of several known SSC self-renewal related genes including, Bcl6b and LIM homeobox 1 (Lhx1). Notably, ETV5 was identified as a regulator of Brachyury and CXC chemokine Receptor, type 4 (Cxcr4), and we show that ETV5 binding to the Brachyury gene promoter region is associated with an active state of transcription. Moreover, in vivo transplantation of SSCs following silencing of Brachyury significantly reduced the number of donor cell-derived colonies formed within recipient mouse testes. These results suggest Brachury is of biological importance, and functions as part of GDNF/ETV5 signaling to promote self-renewal of mouse SSCs cultured in vitro. Microarray gene expression analysis was conducted with Affymetrix Mouse 430 2.0 GeneChips (Affymetrix Inc.).Following with gene knockdown, total RNA from spermatogonial stem cells was converted to cDNA. There are total 16 samples (Four groups and four samples per group) Negative control (N), Bcl6b Knockdown (B), Etv5 knockdown (E), and Pou3f1 knockdown (O), respectively.

Project description:The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor, we found that expression of the hominid-restricted retrogene POU5F1B through aberrant activation of a primate-specific endogenous retroviral promoter is a strong negative prognostic CRC biomarker. Correlating this observation, we could demonstrate that POU5F1B fosters the proliferation and metastatic potential of CRC cells. We further determined that POU5F1B, in spite of its phylogenetic relationship with the POU5F1/OCT4 transcription factor, is a membrane-enriched protein that associates with protein kinases and known targets or interactors as well as with cytoskeleton-related molecules, and induces intracellular signaling events and the release of trans-acting factors involved in cell growth and cell adhesion. As POU5F1B is an apparently non-essential gene only lowly expressed in normal tissues, and as POU5F1B-containing TcGTs are detected in other tumors besides CRC, our data provide interesting leads for the development of cancer therapies.
