Canonical Wnt signaling is critically involved in normal hematopoietic development and the self-renewal process of hematopoietic stem cells (HSCs). Deregulation of this pathway has been linked to a large variety of cancers, including different subtypes of leukemia. Lef-1 is a major transcription factor of this pathway and plays a pivotal role in lymphoid(More)
UNLABELLED Over the past years growing knowledge about biological processes and pathways revealed complex interaction networks involving many genes. In order to understand these networks, analysis of differential expression has continuously moved from single genes towards the study of gene sets. Various approaches for the assessment of gene sets have been(More)
Activation of CXC-motif-chemokine receptor 4 (CXCR4) signaling by the chemokine CXCL12 (also known as SDF-1α) plays a key role in many physiological processes including organogenesis, hematopoiesis, and immune responses. Consequently, CXCR4 or CXCL12 knockouts in mice are embryonic lethal because of impaired hematopoiesis, defects in organ development, and(More)
BACKGROUND The development of expression-based gene signatures for predicting prognosis or class membership is a popular and challenging task. Besides their stringent validation, signatures need a functional interpretation and must be placed in a biological context. Popular tools such as Gene Set Enrichment have drawbacks because they are restricted to(More)
