Expression data from Bmi1-overexpressing Ink4a-Arf-null hepatoblasts

ABSTRACT: Forced expression of Bmi1 accelerated the self-renewal of hepatic stem/progenitor cells and eventually induced their transformation in an in vivo transplant model. The Ink4a/Arf locus, which encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf, is a pivotal target of Bmi1. Therefore, it would be of importance to understand the contribution of the Ink4a/Arf locus to Bmi1 oncogenic functions in cancer and search for as-yet-unknown Bmi1 target genes other than Ink4a/Arf. We used microarrays to explore novel candidate downstream targets for Bmi1 in hepatic stem/progenitor cells

Transcription profiling of mouse Bmi1-overexpressing Ink4a-Arf-null hepatoblasts

We used microarrays to explore novel candidate downstream targets for Bmi1 in hepatic stem/progenitor cells Experiment Overall Design: Purified Dlk-positive hepatoblasts at day 28 of culture were subjected to RNA extraction and hybridization on Affymetrix microarrays. Data were obtained for quadrant samples from four independent experiments.

Expression data from Bmi1-null c-Kit+Sca-1+Lineage marker- (KSL) hematopoietic stem/progenitor cells

Project description:Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells. Purified KSL cells from BM of wild-type, Bmi1-/-, Ink4a-/-Arf-/-, and Bmi1-/- Ink4a-/-Arf-/- mice were subjected to RNA extraction and hybridization on Affymetrix microarrays.

Expression data from Bmi1-null common myeloid progenitor (CMP)

Project description:Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells. Purified CMP from BM of recipient mice repopulated with wild-type, Ink4a-/-Arf-/-, and Bmi1-/- Ink4a-/-Arf-/- BM cells were subjected to RNA extraction and hybridization on Affymetrix microarrays.

Transcriptional profiling of 2D colonies derived from WT, Bmi1-/-, and Bmi1-/-;Ink4a/Arf Labial cervical loops

Project description:This experiment is aimed at determining the genetic signature of dental stem cell colonies grown in vitro and how that signature changes when Bmi1 activity is removed. Another question to be answered by the experiment is whether Bmi1 has alternate targets besides Ink4a/Arf.

An inter-dependent network of enhancers regulates INK4a/ARF locus

Project description:By functionally dissecting densest enhancer cluster in the gene desert at 9P21 locus, we identified a non-redundant inter-dependent enhancer network that functions over long distances, the perturbation in any enhancer in the network results in the complete collapse of entire enhancer cluster and target genes activity. The enhancer network can be targeted to regulate INK4a/ARF locus in associated pathophysiologies and cancers.
