Pathway Analysis of Glioblastoma Tissue after Preoperative Treatment with the EGFR Tyrosine Kinase Inhibitor Gefitinib-A Phase II Trial

Amplification of the epidermal growth factor receptor (EGFR) gene is one of the most common oncogenic alterations in glioblastoma (45%) making it a prime target for therapy. However, small molecule inhibitors of the EGFR tyrosine kinase showed disappointin ...

RBP-Jκ-dependent Notch signaling enhances retinal pigment epithelial cell proliferation in transgenic mice

Freddy Radtke, Friedrich Beermann, Iraz Toprak Aydin

The Notch signaling pathway is an ubiquitous cell-cell interaction mechanism, which is essential in controlling processes like cell proliferation, cell fate decision, differentiation or stem cell maintenance. Recent data have shown that Notch signaling is ...

Epigenetic Modification of the FMR1 Gene in Fragile X Syndrome Is Associated with Differential Response to the mGluR5 Antagonist AFQ056

Nouchine Hadjikhani, Fei Chen

Fragile X syndrome (FXS) is an X-linked condition associated with intellectual disability and behavioral problems. It is caused by expansion of a CGG repeat in the 5' untranslated region of the fragile X mental retardation 1 (FMR1) gene. This mutation is a ...

The Cell Differentiation Status Influences the Outcome of Notch-Induced Malignancy

Caroline Poisson

The Notch signaling cascade is a well conserved pathway that regulates many aspects of embryonic development and plays a crucial role in the differentiation process and tissue homeostasis in multiple organs of adult species. Several human pathological diso ...

The Wnt inhibitory factor 1 (WIF1) is targeted in glioblastoma and has a tumor suppressing function potentially by induction of senescence

Mauro Delorenzi

Gene expression-based prediction of genomic copy number aberrations in the chromosomal region 12q13 to 12q15 that is flanked by MDM2 and CDK4 identified Wnt inhibitory factor 1 (WIF1) as a candidate tumor suppressor gene in glioblastoma. WIF1 encodes a sec ...

β-catenin represses expression of the tumour suppressor 15-prostaglandin dehydrogenase in the normal intestinal epithelium and colorectal tumour cells

Paloma Ordonez Moran

BACKGROUND: Cyclooxygenase-2 (COX-2) overexpression in colorectal cancer increases levels of its pro-tumorigenic product prostaglandin E2 (PGE(2)). The recently identified colorectal tumour suppressor 15-prostaglandin dehydrogenase (15-PGDH) catalyses pros ...

Identification and Preclinical Validation of Novel Inhibitors of the Notch Pathway

Rajwinder Lehal

Notch signaling is among one of the highly conserved developmental pathways. Because of its role in the regulation of stem cell self-renewal and cell fate decisions, Notch signaling maintains tissue homeostasis in several organs such as thymus, skin and in ...

Imaging guided trials of the angiogenesis inhibitor sunitinib in mouse models predict efficacy in pancreatic neuroendocrine but not ductal carcinoma

Douglas Hanahan

Preclinical trials in mice represent a critical step in the evaluation of experimental therapeutics. Genetically engineered mouse models (GEMMs) represent a promising platform for the evaluation of drugs, particularly those targeting the tumor microenviron ...

Notch2 governs the rate of generation of mouse long- and short-term repopulating stem cells

Freddy Radtke

HSCs either self-renew or differentiate to give rise to multipotent cells whose progeny provide blood cell precursors. However, surprisingly little is known about the factors that regulate this choice of self-renewal versus differentiation. One candidate i ...

Dll1- and Dll4-mediated Notch signaling is required for homeostasis of intestinal stem cells

Freddy Radtke, Ute Koch, Luca Pellegrinet, Shuang Chen

BACKGROUND & AIMS: Ablation of Notch signaling within the intestinal epithelium results in loss of proliferating crypt progenitors, due to their conversion into post-mitotic secretory cells. We aimed to confirm that Notch was active in stem cells (SC), inv ...
