- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Most tumors are epithelial-derived, and although disruption of polarity and aberrant cellular junction formation is a poor prognosticator in human cancer, the role of polarity determinants in oncogenesis is poorly understood. Using in vivo selection, we identified a mammalian orthologue of the Drosophila polarity regulator crumbs as a gene whose loss of expression promotes tumor progression. Immortal baby mouse kidney epithelial (iBMK) cells selected in vivo to acquire tumorigenicity displayed dramatic repression of crumbs3 (crb3) expression associated with disruption of tight junction formation, apicobasal polarity, and contact-inhibited growth. Restoration of crb3 expression restored junctions, polarity and contact inhibition, while suppressing migration and metastasis. These findings suggest a role for mammalian polarity determinants in suppressing tumorigenesis that may be analogous to the well-studied polarity tumor suppressor mechanisms in Drosophila.

Description
The transcription factor Peroxisome Proliferator-Activated Receptor (PPAR) is an important regulator of hepatic lipid metabolism. While PPAR is known to activate transcription of numerous genes, no comprehensive picture of PPAR binding to endogenous genes has yet been reported. To fill this gap, we performed ChIP-chip in combination with transcriptional profiling on HepG2 human hepatoma cells treated with the PPAR agonist GW7647. We found that GW7647 increased PPAR binding to 4220 binding regions. GW7647-induced binding regions showed a bias around the transcription start site and most contained a predicted PPAR binding motif. Several genes known to be regulated by PPAR, such as ACOX1, SULT2A1, ACADL, CD36, IGFBP1 and G0S2, showed GW7647-induced PPAR binding to their promoter. A GW7647-induced PPAR-binding region was also assigned to SREBP-targets HMGCS1, HMGCR, FDFT1, SC4MOL, and LPIN1, expression of which was induced by GW7647, suggesting cross-talk between PPAR and SREBP signaling. Our data furthermore demonstrate interaction between PPAR and STAT transcription factors in PPAR-mediated transcriptional repression, and suggest interaction between PPAR and TBP and C/EBP in PPAR-mediated transcriptional activation. Overall, our analysis leads to important new insights into the mechanisms and impact of transcriptional regulation by PPAR in human liver and highlight the importance of cross-talk with other transcription factors.
