Affymetrix Human Genome U219 Array (hgu219)
Description
Gene expression profiles of paired normal adjacent mucosa and tumor samples from 98 individuals and 50 healthy colon mucosae, were obtained through Affymetrix Human Genome U219 Arrays. This dataset is in the context of the COLONOMICS project and to query additional information you can visit the project website www.colonomics.org.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Approximately one third of acute myeloid leukemias (AMLs) are characterized by aberrant cytoplasmic localization of Nucleophosmin (NPMc+ AML), consequent to mutations in the NPM putative nucleolar localization signal. These events are mutually exclusive with the major AML-associated chromosomal rearrangements, and are frequently associated with normal karyotype, Fms-like tyrosine kinase (FLT3) mutations and multilineage involvement. We report the gene expression profiles of 78 de novo AMLs (72 with normal karyotype; 6 with non-major chromosomal abnormalities) that were characterized for the subcellular localization and mutation status of NPM. Unsupervised clustering clearly separated NPMc+ from NPMc- AMLs, regardless of the presence of FLT3 mutations or non-major chromosomal rearrangements, supporting the concept that NPMc+ AML represents a distinct entity. The molecular signature of NPMc+ AML includes up-regulation of several genes putatively involved in the maintenance of a stem cell phenotype, suggesting that NPMc+ AML may derive from a multipotent hematopoietic progenitor.
Publication Title
Acute myeloid leukemia bearing cytoplasmic nucleophosmin (NPMc+ AML) shows a distinct gene expression profile characterized by up-regulation of genes involved in stem-cell maintenance.

Description
Pirin (PIR) is a putative transcriptional regulator abundantly expressed in melanocytes and in a subset of primary and metastatic melanomas. Ablation of PIR in the melanoma cell lines results in induction of a senescence-like phenotype.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Pirin (PIR) is a putative transcriptional regulator whose expression is silenced in cells bearing the AML1/ETO and PML/RAR leukemogenic fusion proteins and is significantly repressed in a large proportion of acute myeloid leukemias. PIR expression increases during in vitro myeloid differentiation of primary hematopoietic precursor cells, and ablation of PIR in the U937 myelomonocytic cell line or in murine primary hematopoietic precursor cells results in impairment of terminal myeloid differentiation.
Publication Title
Pirin downregulation is a feature of AML and leads to impairment of terminal myeloid differentiation.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Polycomb group (PcG) proteins form multiprotein complexes, called Polycomb repressive complexes (PRCs). PRC2 contains the PcG proteins EZH2, SUZ12, and EED and represses transcription through methylation of lysine (K) 27 of histone H3 (H3). Suz12 is essential for PRC2 activity and its inactivation results in early lethality of mouse embryos.
Publication Title
The polycomb group protein Suz12 is required for embryonic stem cell differentiation.

Description
Approximately 20% of Acute Myelogenous Leukemia (AML) cases carry the t(8;21) translocation, which involves the AML1 and ETO genes, and express the resulting AML1/ETO fusion protein that functions as a transcriptional repressor by recruiting NCoR/SMRT/HDAC complexes to DNA.
Publication Title
AML1/ETO oncoprotein is directed to AML1 binding regions and co-localizes with AML1 and HEB on its targets.
