Description
Endothelial cells (ECs) express two members of the cadherin family, VE- and N-cadherin. While VE-cadherin induces EC homotypic adhesion, N-cadherin function in ECs remains largely unknown. EC-specific inactivation of either VE- or N-cadherin leads to early foetal lethality suggesting that these cadherins play a non-redundant role in vascular development.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
In order to identify genes regulated by VE-cadherin expression, we compared a mouse VE-cadherin null cell line (VEC null) with the same line reconstituted with VE-cadherin wild type cDNA (VEC positive). The morphological and functional properties of these cell lines were described previously [Lampugnani,M.G. et al. Contact inhibition of VEGF-induced proliferation requires vascular endothelial cadherin, beta-catenin, and the phosphatase DEP-1/CD148. J. Cell Biol. 161, 793-804 (2003)]. By Affymetrix gene expression analysis we found several genes up-regulated by VE-cadherin, among which claudin-5 reached remarkably high levels. The up-regulation of these genes required not only VE-cadherin expression but also cell confluence suggesting that VE-cadherin clustering at junctions was needed.
Publication Title
Endothelial adherens junctions control tight junctions by VE-cadherin-mediated upregulation of claudin-5.

Description
Acute myeloid leukemia (AML) is associated with poor prognosis, and there is a strong need to develop new therapeutic strategies to improve treatments. We performed a cytokine screen with 114 recombinant proteins to identify selective negative regulators of primitive murine AML cells relative to normal bone marrow cells. The top candidate identified was interleukin 4 (IL4), as it showed the most selective inhibition of leukemia cell growth. Stimulating leukemia cells ex vivo with IL4 and transplanting the cells into mice resulted in reduced leukemia burden and prolonged survival compared with controls. In contrast, IL4 did not inhibit the function of normal hematopoietic stem and progenitor cells in long-term bone marrow repopulation assays. Moreover, we found that IL4 treatment of leukemia cells induced Stat6 phosphorylation, and that leukemia cells with Stat6 knocked out using CRISPR/Cas9-genetic engineering were partially resistant to IL4 stimulation, revealing Stat6 as a critical mediator of the IL4 effect. To evaluate whether IL4 has in vivo therapeutic efficacy, we expressed IL4 ectopically in leukemia cells in vivo and also injected IL4 into leukemic mice; both strategies resulted in the suppression of the leukemia cell burden and increased survival. Further analysis revealed that IL4 treatment induces apoptosis in the leukemia cells. Importantly, IL4 exposure also inhibited the growth and survival of primary AML patient cells. In summary, these findings demonstrate that IL4 selectively inhibits AML cells in a Stat6-dependent manner, thus revealing IL4 as a candidate therapeutic agent in AML. IL4 (ProSpec, East Brunswick NJ, USA) was resuspended following the provider guidelines and stored in aliquotes at -80 °C. Mouse MLL-AF9 leukemia cells were provided by Dr. Benjamin Ebert (Brigham and Women’s Hospital, Boston MA, USA). The murine leukemia cells were cultured in SFEM (StemCell Tech) supplemented with 1% penicillin/streptomycin at 37 °C with 5% CO2. Overall design: Mouse MLL-AF9 leukemia cells were grown in 20 ng/mL IL3 with or without IL4 (100 ng/mL) for 18 hours.

Description
Profound changes in cancer cell identity can alter malignant potential and therapeutic response. Loss of the pulmonary lineage specifier NKX2-1 augments the growth of KRAS-driven lung adenocarcinoma and causes pulmonary to gastric transdifferentiation. Here we show that the transcription factors FoxA1 and FoxA2 are required for initiation of mucinous NKX2-1-negative lung adenocarcinomas in the mouse and for activation of their gastric differentiation program. Foxa1/2 deletion severely impairs tumor initiation and causes a proximal shift in cellular identity, yielding tumors expressing markers of the squamocolumnar junction of the gastrointestinal tract. In contrast, stochastic loss of FoxA1/2 expression in NKX2-1-negative tumors is associated with keratinizing squamous differentiation. Using sequential in vivo recombination, we find that FoxA1/2 loss in established KRAS-driven neoplasia is sufficient for direct induction of keratinizing squamous cell carcinomas in the lung. Thus, NKX2-1, FoxA1 and FoxA2 coordinately regulate the growth and identity of lung adenocarcinoma in a context-specific manner. Overall design: Murine lung tumor cells of differing genotypes were isolated by FACS and subjected to single cell analysis using the Fluidigm C1 platform.

Description
Specimens were collected from esophageal adenocarcinoma patients undergoing esophagectomy for adenocarcinoma at the University of Michigan Health System between 1991 and 2004. Written consent was obtained from each patient according to the approval and guidelines of the University of Michigan institutional review board. Patients receiving treatment with chemotherapy and/or radiotherapy prior to surgery were excluded.
