Project description:The Forkhead family of transcription factors comprises numerous members and is implicated in various cellular functions, including cell growth, apoptosis, migration and differentiation.In this study we identified the Forkhead factor FoxQ1 as increased in expression during TGF-beta1 induced changes in epithelial differentiation, suggesting functional roles of FoxQ1 for epithelial plasticity.The repression of FoxQ1 in mammary epithelial cells led to a change in cell morphology characterized by an increase in cell size, pronounced cell-cell contacts and an increased expression of several junction proteins (e.g. E-cadherin). In addition, FoxQ1 knock-down cells revealed rearrangements in the actin-cytoskeleton and slowed down cell cycle G1-phase progression.Furthermore, repression of FoxQ1 enhanced the migratory capacity of coherent mammary epithelial cells.Gene expression profiling of NM18 cells indicated that FoxQ1 is a relevant downstream mediator of TGF-beta1 induced gene expression changes. This included the differential expression of transcription factors involved in epithelial plasticity, e.g. Ets-1, Zeb1 and Zeb2.In summary, this study has elucidated the functional impact of FoxQ1 on epithelial differentiation

Project description:Two glioblastoma cell lines (LN18 and HS863) were stable transfected with control empty vector (EV) or RNF123-vector (KPC1). The objective of this experiment was to determine NFKB1-targets regulated by RNF123 overexpression in glioblastoma cell lines. To do that LN18 and HS863 cell lines with RNF123 overexpression were compared to control empty vector. In the present study, we utilized the combination of RPPA and RNA-Sequencing. By comparing both datasets, we identified commonly proteins and genes differentially expressed in control versus RNF123-overexpressing cells.

Project description:Numerous epithelial-to-mesenchymal transition (EMT)-promoting transcription factors have been implicated in tumorigenesis or metastasis, as well as chemoresistance of cancer. However, the underlying mechanism mediating these processes is unclear. Here we report that Foxq1, a forkhead box-containing transcription factor and EMT-inducing gene, promotes stemness traits and chemoresistance in mammary epithelial cells. We identify Twist1, Zeb2, and PDGFRM-NM-1 and M-NM-2 as Foxq1 downstream targets using an expression profiling assay. Further studies reveal that PDGFRM-NM-1 and M-NM-2 can be directly regulated by Foxq1, or indirectly through Twist1. Knockdown of both PDGFRM-NM-1 and M-NM-2 shows more significant effects on reversing Foxq1-promoted oncogenesis in vitro and in vivo than knockdown by either PDGFRM-NM-1 or M-NM-2 alone. PDGFRM-NM-2, but not PDGFRM-NM-1, shows potent effects in reversing Foxq1-promoted stemness traits. Moreover, pharmacological inhibition or gene silencing of PDGFRs sensitize mammary epithelial cells to chemotherapeutic agents in vitro and in vivo. These findings collectively indicate PDGFRs as critical mediators underlying breast cancer tumorigenesis and chemoresistance driven by EMT promoting genes, which have potential clinical implications for cancer therapy. The purpose of these experiments is to investigate the downstream targets of several transcriptional factors including Foxq1 and IRX5. Another purpose is to compare the expression pattern between basal-like breast cancer cells including MDA-MB231, SUM159 and SUM1315.
