Lower ROS levels in CSCs are associated with increased expression of free radical scavenging systems. This is accompanied by a translocation of the p53 protein from the cytoplasm to the nucleus. Westin, E. H., Gorse, K. M., Clarke, M. F. THE PROLIFERATION OF AML-193 IS REGULATED BY MULTIPLE HEMATOPOIETIC GROWTH-FACTORS AND CYTOKINES. View details for Web of Science ID 000168861600008. We have previously investigated the expression of Bcl-x in neuroblastoma (NB) cell lines and have shown that Bcl-xL is expressed and functions to inhibit chemotherapy-induced apoptosis. Comparing ChIP results for two modified histone protein targets, we showed our automated microfluidic ChIP (AutoChIP) from 2,000 cells to be comparable to that of conventional ChIP methods using 50,000-500,000 cells. We report here that the genes for HLA class I antigens are also highly methylated in the T-ALL T-cell lines relative to the same genes in the ATL T-cell lines, normal peripheral blood T cells, and autologous normal B-cell lines.

Furthermore, these approaches are not feasible for primary tumor cells that cannot survive tissue culture conditions or that may change phenotype in rats. Inflammation disrupts tissue architecture and function, thereby contributing to the pathogenesis of diverse diseases; the signals that promote or restrict tissue inflammation thus represent potential targets for therapeutic intervention. An alternately spliced c-myb mRNA encodes a truncated version of p75c-myb (mbm2) that includes the DNA binding region and nuclear localization signal present in the c-myb protein, but does not contain the transcriptional regulatory regions. The results indicate that locally produced GM-CSF and IL-3 do augment hematopoiesis for several weeks in culture. Street. In six of seven tumors examined, Thy1+CD24+ cancer cells, which constituted approximately 1%-4% of tumor cells, were highly enriched for cells capable of regenerating new tumors compared with cells of the tumor that did not fit this profile ("not-Thy1+CD24+"). Moreover, we demonstrate that only CSC implants invade into surrounding stroma with structures similar to developing mammary ducts (nine for CSC and one for non-CSC).

Oncolytic adenoviruses with restricted replication can be produced if the expression of crucial transcription units of the virus is controlled by tissue- or tumor-specific promoters. Al-Hajj, M., Wicha, M. S., Benito-Hernandez, A., Morrison, S. J., Clarke, M. F. Mesenchymal tumor cells drive adaptive resistance of Trp53-/- breast tumor cells to inactivated mutant Kras. These latter cell lines do express HLA-DR alpha-mRNA, as well as HLA-DR surface antigens. The existence of CSCs mandates careful analysis and comparison of normal tissue stem cells and CSCs to identify differences between the two cell types. Cancer stem cells and tumor metastasis: First steps into uncharted territory, Bmi-1-green fluorescent protein-knock-in mice reveal the dynamic regulation of Bmi-1 expression in normal and leukemic hematopoietic cells.

Among patients with stage II cancer, the difference in 5-year disease-free survival was significant both in the discovery data set (49% among 15 patients with CDX2-negative tumors vs. 87% among 191 patients with CDX2-positive tumors, P=0.003) and in the validation data set (51% among 15 patients with CDX2-negative tumors vs. 80% among 106 patients with CDX2-positive tumors, P=0.004). Hosen, N., Yamane, T., Muijtjens, M., Pham, K., Clarke, M. F., Weissman, I. L. Phenotypic characterization of human colorectal cancer stem cells. However, the identity and function of cells expressing EMT-associated genes in normal murine mammary gland homeostasis and human breast cancer still remains under debate. To test this hypothesis, murine erythroleukemia cells were transfected with bcl-XL and p53ts. Solid tumors such as breast cancers contain heterogeneous populations of neoplastic cells. In spite of substantial differences in the extent of methylation of class I-related genes, no obvious differences exist among these cell types in their levels of expression of HLA-A and -B antigens. Facebook gives people the power. 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. This article discusses the role of the Bcl-2 family of proteins in the light of these findings. Three clusters, miR-200c-141, miR-200b-200a-429, and miR-183-96-182 were downregulated in human BCSCs, normal human and murine mammary stem/progenitor cells, and embryonal carcinoma cells. Professor. This promoter induces transcriptional activation of the E1a and E4 units in response to estrogens in cells that express the ERs. Testicular cancer patients refractory or in relapse after primary chemotherapy have < or =25% 5-year progression-free survival with salvage. This tumorigenic cell population could be identified prospectively and consistently had definable and identical phenotype. Bystander cells did not display enhanced type I IFN transcription but had elevated levels of certain IFN-stimulated genes, presumably in response to exogenous IFNs secreted from immune cells. Wild-type p53 plays a crucial role in the control of apoptosis following ionizing radiation (IR); conversely, mutant p53 is associated with IR resistance.

These studies suggest that there is a cancer stem cell compartment in the MMTV-Wnt-1 murine breast tumor and that there is a clinical utility of this model for the study of cancer stem cells. Single-cell transcriptomics of 20 mouse organs creates a Tabula Muris. A., Sim, S., Okamoto, J., Johnston, D. M., Qian, D., Zabala, M., Bueno, J., Neff, N. F., Wang, J., Shelton, A. Bcl-XS overexpressed in MCF-7 cells by stable transfection does not affect viability by itself but induces a marked increase in chemosensitivity to VP-16 or taxol. The mechanism of leukaemogenic transformation by human T-cell leukaemia/lymphoma virus (HTLV), a retrovirus implicated in the aetiology of certain adult T-cell leukaemias and lymphomas, is unknown but is conceivably associated with the expression of the cellular analogues of retroviral oncogenes. View details for DOI 10.1016/j.stemcr.2020.12.012. Here, to reveal mechanisms by which different neoplastic cells generate this dominant 'don't eat me' signal, we analyse the CD47 regulatory genomic landscape. We extend this concept to identify cell types of origin using the Tabula Sapiens transcriptomic cell atlas as well as individual tissue transcriptomic cell atlases in combination with the Human Protein Atlas RNA consensus dataset. miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway. The tumors that arose from purified CD44(+) cells reproduced the original tumor heterogeneity and could be serially passaged, thus demonstrating the two defining properties of stem cells: ability to self-renew and to differentiate. View details for Web of Science ID 000166430900009. Murine CD18 can be expressed on the cell surface of up to 20% of the mature cells generated by the culture system, suggesting that clinically significant levels of gene transfer may be occurring. 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. Paneth cells contribute to the small intestinal niche of Lgr5(+) stem cells. The successful ex vivo reconstruction of human bone marrow is an extraordinarily important basic scientific and clinical goal. Individual phenotypic cancer cell subsets were purified, and their tumor-initiating properties were investigated by injection in NOD/SCID mice. Office Hours: Tuesday 12:00-1:00PM; Thursday 2:00-3:00PM; Friday 10:30-11:30AM. All measured metabolic rates increased with increased medium exchange rates and accelerated sharply between exchange rates of 3.5/week and 7/week. The amine-derivatized biotinylated GM-CSF analogues retained biological activity, could specifically label cell surface receptors, and may be useful nonradioactive probes with which to study GM-CSF receptor cytochemistry and receptor modulation by flow cytometry. View details for Web of Science ID A1990DY35100036. Department of Biology. Human tumors where evidence of cancer stem cells has been published include tumors of the breast, brain, pancreas, head and neck, and colon. We propose the use of this promoter for transcriptional targeting of breast cancer. Liu, H., Patel, M. R., Prescher, J. DP16-1 cells which were untransfected or co-transfected with wtp53 and bcl-2 displayed characteristics of cells undergoing necrosis. Established HTLV-infected cell lines constitutively express viral RNA. Just months into the Biden-Harris administration, the change in tone, message, and approach to transatlantic relations is palpable. identify miR-22 as both a repressor of TET proteins and a powerful oncogene in the mammary epithelium and hematopoietic system. Inhibition of TLR2, its co-receptor CD14, or its downstream targets MYD88 and IRAK1 inhibits growth of human breast cancers in vitro and in vivo. To characterize further the function of these two domains, we demonstrate in this report that the previously described major nuclear localization signal works together with Lys(305)-Arg(306) to form a bipartite and functional nuclear localization sequence (NLS) for p53 nuclear import. View details for Web of Science ID 000316614600063. This conserved requirement for Bmi-1 to promote self-renewal and to repress p16Ink4a expression suggests that a common mechanism regulates the self-renewal and postnatal persistence of diverse types of stem cell. Profiles. Control cultures that were exposed to conCM after 4 weeks in culture significantly improved their cell productivity during the latter 4 weeks of culture compared with control. Professor William Clarke. Chandhasin, C., Yoo, S., Del Rosario, J., Chen, Y. K., Stafford, J., Perabo, F., Clarke, M. F.

Thus, loss of expression of the alpha-catenin tumor suppressor in hematopoietic stem cells may provide a growth advantage that contributes to human MDS or AML with del(5q). Cell surface GM-CSF receptor binding was characterized by the binding of the analogues to human neutrophils, with detection by fluorescein-conjugated avidin and fluorescence-activated cell sorting. These findings have implications for the development of effective therapeutic agents targeting tumor-initiating cells. Michael Clarke Duncan was born on December 10, 1957 in Chicago, Illinois. The GM-CSF production by the transfected 3T3 cells was stable but exhibited substantial transient increases during periods of cell proliferation, demonstrating that the secretion of transfected gene products can be highly modulated even when the cDNA is driven from a constitutive promoter. Weber, B. L., Westin, E. H., Clarke, M. F. ALTERNATIVE SPLICING OF THE HUMAN C-MYB GENE. 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. Ageing is the single greatest cause of disease and death worldwide, and understanding the associated processes could vastly improve quality of life. His writingson justice, ethics, democracy, and markets--have been translated into 27 languages. Comparison of IRF3 and NF-B induction in STAT1(-/-) mice revealed that murine but not simian RRV mediated accumulation of IkB- protein and decreased transcription of NF-B-dependent genes. The molecular mechanisms that limit the proliferation capacity of multipotent progenitors and other more mature progenitors are not fully understood. Within the colon, the Hedgehog protein signal does not act directly on the epithelium itself, but on underlying stromal cells to induce expression of IL-10, an immune-modulatory cytokine long known to suppress inflammatory intestinal damage. Clarke, M. F., Gelmann, E. P., Reitz, M. S. RELATION OF RESPIRATORY BURST AND ARACHIDONATE METABOLISM DURING PHAGOCYTOSIS BY GUINEA-PIG ALVEOLAR MACROPHAGES. A better understanding of the molecular mechanisms underlying metastasis is needed to develop more effective treatments. Using 2 independent analyses, we identified multiple pathways that are aberrantly regulated in leukemic stem cells compared with normal HSC. We found that each antibody inhibited tumor growth and that the combination of the two antibodies was more effective than either alone. 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. Specifically, in the presence of CSC, we identified an increased number of branches, branch points, ducts which have greater than 40 branches (5/33 for CSC and 0/39 for non-CSC), and histological evidence of increased branching. View details for Web of Science ID A1984TY56600006. We thus identify stromal cells as cellular coordinators of colon inflammation and suggest their pharmacologic manipulation as a potential means to treat colitis. Purified RGS18 interacts with the alpha subunit of both G(i) and G(q) subfamilies. Dr. Michael F. Clarke is the Karel and Avice Beekhuis Professor in Cancer Biology and Associate Director of the Stanford Institute for Stem Cell and Regenerative Medicine. 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. He has a long-standing interest in the impact of fire upon fauna. Clones with various levels of c-sis expression were generated by transfecting NIH 3T3 cells with a plasmid that expressed the human c-sis cDNA and the TN5 neomycin-resistance gene. The development of CSC-targeted treatments will face a number of potential hurdles, including normal stem cell toxicity and the acquisition of treatment resistance, which must be considered in order to maximize the chance that such therapies will be successful.

In the absence of Bmi-1, the cyclin-dependent kinase inhibitor gene p16Ink4a is upregulated in neural stem cells, reducing the rate of proliferation. This apparent paradox is the focus of our interest. Cytoplasmic sequestration of the p53 tumor suppresser protein has been proposed as a mechanism involved in abolishing p53 function. Epigenetic regulation of normal and cancer stem cells, Neurobiology: At the root of brain cancer, Chronic myelogenous leukemia - Identifying the hydra's heads, Therapeutic implications of cancer stem cells. When viability was measured 24 h post-radiation, cells that had been briefly exposed to wtp53 immediately after X-ray irradiation had decreased survival as compared to unirradiated cells expressing wtp53 or X-ray irradiated DP16-1 cells. Analysis of HL-60 cells, a myeloid leukemia line with deletion of the 5q31 region, showed that the CTNNA1 promoter of the retained allele is suppressed by both methylation and histone deacetylation. CD47 is a ligand for SIRP, a protein expressed on macrophages and dendritic cells. We have designed a microfluidic device to perform sensitive ChIP analysis on low cell numbers in a rapid, automated fashion while preserving the specificity of the assay. CD47 is a cell surface molecule that inhibits phagocytosis of cells that express it by binding to its receptor, SIRP, on macrophages and other immune cells. Overall, we demonstrate a novel approach for imaging physiologic and pathological remodeling. Our results indicate that constitutive expression of a nontruncated human c-myb cDNA can exert profound effects on erythroid differentiation and argue for a causal role of c-myb in the F-MEL differentiation process. While the transfected cells grew normally in the presence of mutant p53 (37.5 degrees C), wild-type p53 (32.5 degrees C) was associated with a rapid loss of cell viability. Some factors that regulate this process of self-renewal are conserved from fruit fly to humans. Associate Professor of Instruction; PhD. 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. erenakgun@g.harvard.edu. HSCs have the ability to self-renew, while MPP cells have lost the capacity for self-renewal. Disruption of the regulation of self-renewal results in cancer. The CD44(+)CD24(+)ESA(+) pancreatic cancer cells showed the stem cell properties of self-renewal, the ability to produce differentiated progeny, and increased expression of the developmental signaling molecule sonic hedgehog. The IGS was also associated with the prognosis in medulloblastoma (P=0.004), lung cancer (P=0.03), and prostate cancer (P=0.01). Here we describe a method for the rapid incorporation of exogenous promoters into the E1A and E4 regions of the human adenovirus type 5 genome. Knockdown of KIT decreased proliferation of colon cancer cell lines and growth of xenograft tumors in mice compared with control cells. He is so driven about his work and is so charismatic to his students. Stem cells in normal breast development and breast cancer. Room 424:1 Advanced Engineering Building (49) . Infection with this vector induced apoptosis in vitro. A., Clarke, M. F., Weissman, I. L. MicroRNAs regulate breast cancer stem cells and spontaneous metastases in orthotopic xenograft models. These results indicate that a basic domain other than the well defined NLS is required for the nuclear import of p53. These pathways are commonly repressed in cancer, suggesting a mechanism by which early progenitor cells could gain the ability to self-renew and become malignant with further oncogenic mutations. In combination with geometric and dynamic approaches to reconstructing physiological bone marrow microenvironments, we believe that this approach has promise for reconstructing human bone marrow ex vivo, thereby permitting its application to a variety of basic and clinical problems. The miR-30c-VIM/TWF1 signaling cascade is also associated with clinical outcome in breast cancer patients. Who we Are. We were able to distinguish the tumorigenic (tumor initiating) from the nontumorigenic cancer cells based on cell surface marker expression. Liu, H., Qian, D., Lin, J., Lobo, N., Zhang, H., Dalerba, P., Shimono, Y., Diehn, M., Jeffrey, S., Clarke, M. Isolation and molecular characterization of cancer stem cells in MMTV-Wnt-1 murine breast tumors. We demonstrate that nonadherent mammospheres are enriched in early progenitor/stem cells and able to differentiate along all three mammary epithelial lineages and to clonally generate complex functional structures in reconstituted 3D culture systems. 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. RNA splicing programs define tissue compartments and cell types at single-cell resolution. In patients with colorectal cancer (CRC) that metastasizesto the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. LONDON Dancer, choreographer, ex-heroin addict, prodigal son, perfectionist, art-world darling, club-world star: Michael Clark was for a long time . in Pounds- 159 lbs. Upon inactivation of KrasG12D , tumors initially regress and enter remission. Although these culture conditions still fall short of full reconstitution of functional human bone marrow, they provide an improved approach to hematopoietic cell culture that may permit the expansion and manipulation of progenitor cells in vitro. Transplanted fetal liver and bone marrow cells obtained from Bmi-1-/- mice were able to contribute only transiently to haematopoiesis. Stem cell biology has come of age. Five thousand cDNA clones with very low hybridization signals were selected for sequencing and further analysis using microarrays on glass slides. Many cancers overexpress a member of the bcl-2 family of inhibitors of apoptosis. In recent years solid tumors were studied utilizing similar techniques in mice. Sci. Following synchronization by density arrest, transfected cells released into G1 at 32.5 degrees C were found to lose viability more rapidly than did randomly growing cultures.

This functional subset of cancer cells is operationally defined as the "cancer stem cell" (CSC) subset. As we continue to advance clinically and technologically in the field of colorectal tumor biology, ourgoal should be continuedrefinement of predictive and prognostic studiesto decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailoredmultidisciplinary approach to cancer care. Two populations of cells, HSCs and MPP cells, were compared for differential gene expression using microarray analysis. Taken together, these results suggest that Bcl11b acts as acentral intrinsic regulator of mammary epithelial stem cell quiescence and exhaustion and is necessary for long-term maintenance of the mammary gland. Up to one-third of the long-term culture initiating cell (LTC-IC) are genetically modified by the culture conditions. Pulse induction of p53 alone did not affect Shep-1 cell viability, while induction of p53, followed by IR, resulted in cell death and DNA fragmentation proportional to the dose of IR and the level of p53 expression.

Nuovo ateismo o neo-ateismo, anche nella grafia neoateismo (in inglese New Atheism), una corrente di pensiero che raccoglie le posizioni promosse da alcuni atei del XXI secolo. We therefore propose to initiate a phase I clinical trial to test the safety of this virus in women with breast cancer undergoing high does chemotherapy and autologous BMT. MicroRNAs (miRNAs) are important regulators of stem and progenitor cell functions. Michael Clark. This phenotypic diversity is driven by a small subset of mammary tumour stem cells. The results of in vitro GTPase single-turnover assays using Galpha(i) indicated that RGS18 accelerates the intrinsic GTPase activity of Galpha(i). When applied to diverse tissue types and organisms, CytoTRACE outperformed previous methods and nearly 19,000 annotated gene sets for resolving 52 experimentally determined developmental trajectories. Many of these mutations affect cell proliferation and survival. Kohrt, H. E., Houot, R., Weiskopf, K., Goldstein, M. J., Scheeren, F., Czerwinski, D., Colevas, A. D., Weng, W., Clarke, M.

In the discovery data set, which included 466 patients, the rate of 5-year disease-free survival was lower among the 32 patients (6.9%) with CDX2-negative colon cancers than among the 434 (93.1%) with CDX2-positive colon cancers (hazard ratio for disease recurrence, 3.44; 95% confidence interval [CI], 1.60 to 7.38; P=0.002). Finally, we show evidence that these properties are maintained in the context of an adenoviral vector (AdEHhrk). Complete protection from cytotoxicity caused by this drug mechanisms that limit the proliferation capacity of multipotent progenitors and more.
