F., Lanza, R., Gearhart, J., Hogan, B., Melton, D., Pedersen, R., Thomas, E. D., Thomson, J., Wilmut, Colorectal Cancer Stem Cells Are Enriched in Xenogeneic Tumors Following Chemotherapy. When isolated from mouse colon, cKit(+) cells promoted formation of organoids from Lgr5(+) stem cells, which expressed Kitl/stem cell factor, the ligand for cKit. With noninvasive imaging approaches, as few as 10 cells of stably labeled BCSCs could be tracked in vivo, enabling studies of early tumor growth and spontaneous metastasis. In contrast, normal hematopoietic progenitor cells and primitive cells capable of repopulating severe combined immunodeficient mice were refractory to killing by the bcl-xs adenovirus. Three seminoma patients remain progression-free. Natl. FUKUNAGAJOHNSON, N., Ryan, J. J., Wicha, M., Nunez, G., Clarke, M. F. OVEREXPRESSION OF BCL-X(S), SENSITIZES MCF-7 CELLS TO CHEMOTHERAPY-INDUCED APOPTOSIS. Here we show that the gene encoding alpha-catenin (CTNNA1) is expressed at a much lower level in leukemia-initiating stem cells from individuals with AML or MDS with a 5q deletion than in individuals with MDS or AML lacking a 5q deletion or in normal hematopoietic stem cells. These results suggest that radiation-induced cell death occurs by both p53-dependent and p53-independent pathways. Bcl11b(high) cells are enriched for cells that can regenerate mammary glands in secondary transplants. A., Chen, L., Levy, R. Removal of lactate dehydrogenase-elevating virus from human-in-mouse breast tumor xenografts by cell-sorting. Liu, R., Wang, X., Chen, G. Y., Dalerba, P., Gurney, A., Hoey, T., Sherlock, G., Lewicki, J., Shedden, K., Clarke, M. F. Bmi-1 dependence distinguishes neural stem cell self-renewal from progenitor proliferation. In human breast cancers, a phenotypically distinct minority population of tumorigenic (TG) cancer cells (sometimes referred to as cancer stem cells) drives tumor growth when transplanted into immunodeficient mice. A locus on chromosome 17, including the H-2 complex, was significantly linked to the frequency of long-term self-renewing HSCs but showed no evidence of linkage to the frequency of restricted progenitors. We show that a set of active constituent enhancers, located within the two CD47 SEs, regulate CD47 expression in different cancer cell types and that disruption of CD47 SEs reduces CD47 gene expression.

Therapeutic Implications of the Cancer Stem Cell Hypothesis, Dysregulated gene expression networks in human acute myelogenous leukemia stem cells. Growing up on Chicago's South Side in the 1960s and 1970s, Michael Clarke Duncan experienced poverty and crime as an unfortunately normal part of life. Major conclusions of the symposium were that the flow cytometry of multiple markers in fresh tissue would remain the standard technique of evaluating cancer-initiating cells and that surrogates need to be developed for both experimental and clinical use. Reya, T., Morrison, S. J., Clarke, M. F., Weissman, I. L. Clinical protocol. As few as 100 cells with this phenotype were able to form tumors in mice, whereas tens of thousands of cells with alternate phenotypes failed to form tumors.

Leukemic peripheral blood lymphocytes from individuals infected with the human T-cell leukemia/lymphoma virus (HTLV) were found to express little or no viral RNA before being put into tissue culture. Dr. Jim Clarke is an Adjunct Professor of Civil and Environmental Engineering and an Adjunct Professor of Earth and Environmental Sciences at Vanderbilt University. Mandel, Michael - Associate Professor: Computer and Information Science Manlow, Veronica B. The data clearly indicate, however, that the class I and class II components of the major histocompatibility complex are unusually hypermethylated in several T-ALL-derived cell lines, while ATL T-cell lines do not substantially differ in this respect from normal peripheral blood T-cells. Taken together, these results suggest that USP16 has an important role in antagonizing the self-renewal and/or senescence pathways in Down's syndrome and could serve as an attractive target to ameliorate some of the associated pathologies. A., Parmiani, G., Castelli, C., Clarke, M. F. Identification of pancreatic cancer stem cells. Using a model in which human breast cancer cells were grown in immunocompromised mice, we found that only a minority of breast cancer cells had the ability to form new tumors. This demands a complex crosstalk between extrinsic signals from the microenvironment and the cell-intrinsic regulators of self-renewal. Recent studies have uncovered a number of Bcl-2-related gene products that regulate apoptosis either negatively or positively, and Bcl-2 forms heterodimers with at least one of these proteins, Bax. [1] Clarke is a former Deputy Vice-Principal and Director of Research Development at King's College London, where he remains a Visiting Professor of Defence Studies. Transformed mammary stem or progenitor cells undergo aberrant differentiation processes that result in generation of the phenotypic heterogeneity found in human and rodent breast cancers. A spacer between this basic domain and NLS I is necessary for the entrance of p53 into the cell nucleus. Single cell transcriptomics is revolutionising our understanding of tissue and disease heterogeneity, yet cell type identification remains a partially manual task. However, at later times X-ray irradiated parental DP16-1 cells also had decreased survival compared to the unirradiated control. Although the existence of mammary stem cells has been suggested by serial transplantation studies in mice, their identification has been hindered by the lack of specific surface markers, and by the absence of suitable in vitro assays for testing stem cell properties: self-renewal and ability to generate differentiated progeny. We studied the effect of the combination of rapid culture medium exchange with the addition of the human hematopoietic growth factors interleukin-3 (IL-3), granulocyte-macrophage colony-stimulating factor (GM-CSF), and erythropoietin (Epo) on the proliferation and differentiation of human long-term bone marrow cultures (LTBMCs). However, multipotent progenitors lack the ability to self-renew, therefore their mitotic capacity and expansion potential are limited and they are destined to eventually stop proliferating after a finite number of cell divisions. These models recapitulate human cancer features not captured with previous models, including spontaneous metastasis in particular, and provide a useful platform for studies of breast tumor initiation and progression. Its expansion is a tightly regulated process, fueled by the mammary stem cells and these cells' unique property of self-renewal. High transduction rates could be obtained even in the absence of polycations, such as Polybrene, which heretofore have been required to achieve reasonable transduction rates. On the basis of the wild-type adenovirus type 5, we have constructed a conditionally replicative adenovirus (Ad5ERE2) in which the E1a and E4 promoters have been replaced by a portion of the pS2 promoter containing two estrogen-responsive elements (EREs). However, the consequences of the underlying gene-dosage imbalance on adult tissues remain poorly understood. Both fragments formed complexes with electrophoretic mobilities of nucleosomes containing the appropriate length of DNA. Chen, E. C., Karl, T. A., Kalisky, T., Gupta, S. K., O'Brien, C. A., Longacre, T. A., De Rijn, M. V., Quake, S. R., Clarke, M. F., Rothenberg, M. E. KIT Signaling Promotes Growth of Colon Xenograft Tumors in Mice and Is Up-Regulated in a Subset of Human Colon Cancers. The pattern of triple mutant multipotent progenitor response to growth factors resembles that of wild-type multipotent progenitors but not wild-type HSCs. We show that single-cell RNA-seq can be used to perform accurate quantitative transcriptome measurement in individual cells with a relatively small number of sequencing reads and that sequencing large numbers of single cells can recapitulate bulk transcriptome complexity. Park, I., Qian, D., Kiel, M., Becker, M., Prohaska, S., Weissman, I., Morrison, S., Clarke, M. Bmi-1 is required for maintenance of adult self-renewing haematopoietic stem cells. These data suggest that the late fall in c-myb levels may be required in order for differentiation to occur. [2] Kim et al.

CD47 is a ligand for SIRP, a protein expressed on macrophages and dendritic cells. Dr Ofer Fridman spoke on CNN about the nature of Russian hybrid warfare, discussed Israel's position in Russia and Ukraine border tensions in The Jerusalem Post and was in The i on whether Russia would attack the UK over the imposed sanctions. We have developed an in vitro cultivation system that allows for propagation of human mammary epithelial cells (HMECs) in an undifferentiated state, based on their ability to proliferate in suspension, as nonadherent mammospheres. This includes loss of a portion of the region involved in transcription activation as well as a separate highly conserved domain. View details for Web of Science ID 000073794800011. Cells were analyzed by real-time quantitative reverse transcription polymerase chain reaction, single-cell gene expression analysis, flow cytometry, and immunohistochemical, immunoblot, and functional assays.

In addition to his clinical duties in the division of Oncology, Dr. Clarke maintains a laboratory focused on two areas of research: i) the control of self-renewal of normal stem cells and their malignant counterparts; and ii) the identification and characterization of cancer stem cells. Direct visualization of human tumor cells in vivo shows two patterns of high-speed migration inside primary tumors: (1) single cells and (2) multicellular streams (i.e., cells following each other in a single file but without cohesive cell junctions). Expression of wild-type p53 phenotype for 24 hr before FdUrd treatment provided HT29 cells with virtually complete protection from cytotoxicity caused by this drug. Isobe, T., Zarnegar, M.

(2007) analyze the relationship between CSC and tumor metastasis. Our data suggest that CSC interact with the microenvironment differently than non-CSC, and that this could eventually be a therapeutic approach for targeting CSC. These breast tumors are comprised of phenotypically diverse populations of breast cancer cells. We identify two distinct super-enhancers (SEs) associated with CD47 in certain cancer cell types. Free UK delivery for orders 30 and over. Notably, these gene sets show similar expression across tissues, differing only in the amplitude and the age of onset of expression. The prognostic role of a gene signature from tumorigenic breast-cancer cells. Tumors originated from EpCAM(high)/CD44+ cells maintained a differentiated phenotype and reproduced the full morphologic and phenotypic heterogeneity of their parental lesions. These include the nuclear import and export signals of p53, inhibition of p53 nuclear import and export by oligomerization, MDM2-mediated p53 nuclear export, and possible roles of p53 phosphorylation in regulating p53 cellular localization. Zabala, M., Lobo, N. A., Seoane, J. Here, we have shown that upon encountering trastuzumab-coated, HER2-overexpressing breast cancer cells, human NK cells become activated and express the costimulatory receptor CD137. Lower concentrations of ETYA (5 x 10(-6) M), which had no effect on the respiratory burst of phagocytosing alveolar macrophages, also inhibited arachidonic acid metabolism. Kohrt, H.

The CD47-signal regulatory protein alpha (SIRPa) interaction is a therapeutic target for human solid tumors. In normal mouse epithelium, LEFTY1 expression in a subset of luminal cells and rare basal cells opposes BMP7 to promote ductal branching. In addition, Usp16 is associated with decreased ubiquitination of Cdkn2a and accelerated senescence in Ts65Dn fibroblasts. The telomerase reverse transcriptase (TERT) promoter and the E2F-1 promoter are preferentially activated in cancer cells.

Usp16 regulation of the Wnt pathway in mouse and human tissues is at least in part mediated by activation of Cdkn2a, a regulator of senescence. View details for Web of Science ID 000089592300005. In the present study, further mutagenesis analyses were carried out between Lys-305 and the major nuclear localization signal (NLS I) of p53. The biotinylated proteins migrated with the same molecular weight as the native, unmodified protein as determined by SDS-PAGE and could be detected by Western blotting with alkaline phosphatase conjugated streptavidin, thus demonstrating the biotin linkage. View details for Web of Science ID 000072317400002. All together, these findings link important stem cell regulators like Bmi1/Usp16 and Cdkn2a to Wnt signaling, and have implications for designing therapies for conditions, like DS, aging or degenerative diseases, where the Wnt pathway is hampered. View details for Web of Science ID 000243488100004. This study thus establishes a key RNA-based feature of developmental potential and a platform for delineation of cellular hierarchies. Heights. Program Affiliations. The existence of CSCs mandates careful analysis and comparison of normal tissue stem cells and CSCs to identify differences between the two cell types. The hair color is Light brown and the eye color is Blue. Here we show that normal mammary epithelial stem cells contain lower concentrations of ROS than their more mature progeny cells. The Bcl-XL protein is a recently discovered member of the bcl-2 family which has been shown to protect cells from some forms of programmed cell death, but has not yet been implicated in the genesis of human carcinomas. A., Issa, J., Clarke, M. F., Look, A. T. Lobo, N. A., Shimono, Y., Qian, D., Clarke, M. F. Cancer stem cells and radiotherapy: New insights into tumor radioresistance. c-sis gene expression has been demonstrated in a variety of human tumors, although generally at levels much lower than those shown to transform cells in vitro. This new model for cancer will have significant ramifications for the way we study and treat cancer. T47D cells were then transfected with a temperature-sensitive mutant of the tumor suppressor p53 (p53ts). 3-7), attempts to identify tumor suppressors within this band have been unsuccessful. Resolution of "averaged" innate immune responses in single IECs thus revealed unexpected heterogeneity in both the induction and subversion of early host antiviral immunity, which modulated host range. It has been reported that Lysine-305 is needed for the nuclear import of the p53 protein (Liang et al., 1998). Using an ELISA assay which quantitates DNA damage, we demonstrate that this sensitization is due to apoptosis, suggesting the therapeutic utility of targeting this pathway. Recently, it has become apparent that some oncogenes and tumor suppressor genes also regulate self-renewal, the process by which stem cells maintain themselves. The results indicate that locally produced GM-CSF and IL-3 do augment hematopoiesis for several weeks in culture. Although cancer cell lines provide invaluable information, their biological properties often differ in crucial ways from de novo cancer cells. Therefore, we set out to identify a potential earlier targetable phenotype. Expression of p16Ink4a and p19Arf in normal HSCs resulted in proliferative arrest and p53-dependent cell death, respectively. These data indicate that the simultaneous regulation of E1A and E4 viral transcription units by the appropriate combination of promoters can increase the tumor selectivity of oncolytic adenoviruses. These findings suggest that deregulated expression of Bcl-xS using an adenovirus may provide a novel mechanism for initiating cell death in tumors that express Bcl-2 or Bcl-xL. Human T-cell leukaemia virus (HTLV), first isolated in the United States from a patient with cutaneous T-cell lymphoma, is a unique horizontally transmitted retrovirus which is highly associated with certain adult T-cell malignancies. Furthermore, these approaches are not feasible for primary tumor cells that cannot survive tissue culture conditions or that may change phenotype in rats. Utilizing a mouse model of AD and human fetal cells harboring mutant amyloid precursor protein, we show cell intrinsic neural precursor cell (NPC) dysfunction precedes widespread inflammation and amyloid plaque pathology, making it the earliest defect in the evolution of the disease. The DR alpha genes in both cell lines are hypermethylated relative to the same genes in T-cell lines infected with human T-cell leukemia virus (HTLV) and derived from patients with adult T-cell leukemia/lymphoma (ATL). According to this second scenario, tumors act as caricatures of their corresponding normal tissues and are sustained in their growth by a pathological counterpart of normal adult stem cells, cancer stem cells. Solid CRC tissues, either primary tissues collected from surgical specimens or xenografts established in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice, were disaggregated into single-cell suspensions and analyzed by flow cytometry. Raised by his single mother, Jean, a house cleaner, on Chicago's South Side, Duncan grew up resisting drugs and alcohol, instead concentrating on school. This effect was associated with a loss of the G1 specificity of p53-mediated cell cycle arrest. Zanini, F. n., Berghuis, B. Interstitial loss of all or part of the long arm of chromosome 5, or del(5q), is a frequent clonal chromosomal abnormality in human myelodysplastic syndrome (MDS, a preleukemic disorder) and acute myeloid leukemia (AML), and is thought to contribute to the pathogenesis of these diseases by deleting one or more tumor-suppressor genes. As well as addressing the patient's medical needs, these highly trained professionals . Both KrasG12D -dependent and KrasG12D -independent tumors display a high level of genomic instability, and KrasG12D -independent tumors harbor numerous amplified genes that can activate the MAPK/ERK signaling pathway. The retrovirus transduced culture continued to produce genetically modified hematopoietic progenitors for up to 6 weeks, the duration of the culture period. Our study demonstrates that microRNA-30c is transcriptionally regulated by GATA3 in breast tumours. The isolation and characterization of these stem cells should help elucidate the molecular pathways that govern normal mammary development and carcinogenesis. Our metastatic cancer models, combined with noninvasive imaging techniques, constitute an integrated approach that could be applied to dissect the molecular mechanisms underlying the dissemination of metastatic CSCs (MCSCs) and to explore therapeutic strategies targeting MCSCs in general or to evaluate individual patient tumor cells and predict response to therapy. CD47 mRNA expression levels correlated with a decreased probability of survival for multiple types of cancer. Through this property, striking parallels can be found between stem cells and cancer cells: tumours may often originate from the transformation of normal stem cells, similar signalling pathways may regulate self-renewal in stem cells and cancer cells, and cancer cells may include 'cancer stem cells' - rare cells with indefinite potential for self-renewal that drive tumorigenesis.
