This report summarizes the major topics discussed and the future directions that research should take. [2] [3] Biography [ edit] To assess CSC-specific remodeling events, we isolated CSC from MMTV-Wnt1 (mouse mammary tumor virus long-term repeat enhancer driving Wnt1 oncogene) breast tumors, a well studied model in which tissue remodeling affects tumorigenesis. In this issue of Cancer Cell, Inoue et al. Together, these data demonstrate a similar yet asynchronous inter- and intra-organ progression of ageing, providing a foundation from which to track systemic sources of declining health at old age. This article discusses the role of the Bcl-2 family of proteins in the light of these findings. We found that adult and fetal mouse and adult human HSCs express the proto-oncogene Bmi-1. In SAOS-2 cells, the mutant p53 was a less efficient inducer of p21/CIP1/WAF1 expression. The prognostic power of the IGS was increased when combined with the wound-response (WR) signature.The IGS is strongly associated with metastasis-free survival and overall survival for four different types of tumors.

To improve prognosis, patients entered a phase I/II tandem dose-escalation trial of carboplatin (1500-2100 mg/m(2)) and etoposide (1200-2250 mg/m(2)) with ABMT. List A-Z. An in vivo reconstitution assay revealed that the frequency of HSCs was 1/16 in Bmi-1high c-kit+ lin -Sca-1+ bone marrow (BM) cells and 1/49 in Bmi-1 high lin- BM cells, suggesting that Bmi-1 may serve as a marker for normal HSCs. This approach may also be used to remove other rodent-specific viruses from models derived from distinct tissues or species with sortable markers, where virus does not replicate in the cells to be purified.

Access is controlled by the 1936 Montreux Convention that gives Turkey the right to close the straits in times of war. A., Park, I. K., Ford, P. S., Kiel, M. J., Schork, N. J., Weissman, I. L., Clarke, M. F. Stem cells, cancer, and cancer stem cells. This sequential antibody strategy, combining a tumor-targeting antibody with a second antibody that activates the host innate immune system, may improve the therapeutic effects of antibodies against breast cancer and other HER2-expressing tumors. 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type 5, we have constructed a conditionally replicative adenovirus (Ad5ERE2) in which the E1a and E4 promoters have been replaced by a portion of the pS2 promoter containing two estrogen-responsive elements (EREs). Gulati, G. S., Sikandar, S. S., Wesche, D. J., Manjunath, A. n., Bharadwaj, A. n., Berger, M. J., Ilagan, F. n., Kuo, A. H., Hsieh, R. W., Cai, S. n., Zabala, M. n., Scheeren, F. A., Lobo, N. A., Qian, D. n., Yu, F. B., Dirbas, F. M., Clarke, M. F., Newman, A. M. Ageing hallmarks exhibit organ-specific temporal signatures. The in vitro culture of mouse bone marrow (Dexter cultures) has allowed a detailed analysis of the biology of murine hematopoiesis. Ryan, J. J., Danish, R., Gottlieb, C. A., Clarke, M. F. C-MYB EFFECTS ON KINETIC EVENTS DURING MEL CELL-DIFFERENTIATION. The coordinated downregulation of three microRNA clusters and the similar functional regulation of clonal expansion by miR-200c provide a molecular link that connects BCSCs with normal stem cells. Furthermore, in several other nonhematopoietic tissues, cells could be separated into distinct subpopulations with differential Bmi-1 expression. Down's syndrome results from full or partial trisomy of chromosome 21. This makes it virtually impossible to infect the majority of tumor cells in vivo and results in inadequate gene transfer. Solid tumors arise in organs that contain stem cell populations. The retrovirus transduced culture continued to produce genetically modified hematopoietic progenitors for up to 6 weeks, the duration of the culture period. 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. Regulation of the Wnt pathway in stem cells and primary tissues is still poorly understood. miR-200c inhibited the clonal expansion of breast cancer cells and suppressed the growth of embryonal carcinoma cells in vitro. 2010). We present a simple single tube proximity ligation technique, targeted chromatin ligation, that captures histone modification patterns with only 200 cells. In 2007, he became the Director of the Royal United Services Institute. Just months into the Biden-Harris administration, the change in tone, message, and approach to transatlantic relations is palpable. A Quiescent Bcl11b High Stem Cell Population Is Required for Maintenance of the Mammary Gland. Stem cells in normal breast development and breast cancer. Chandhasin, C., Yoo, S., Del Rosario, J., Chen, Y. K., Stafford, J., Perabo, F., Clarke, M. F. Depletion of Trp53 and Cdkn2a Does Not Promote Self-Renewal in the Mammary Gland but Amplifies Proliferation Induced by TNF-. Murine RV EW robustly activated type I IFNs and several antiviral genes (IFN-stimulated genes) in the intestine by bulk analysis, the source of induced IFNs primarily being hematopoietic cells. (2002) demonstrate that the CED-1 homolog, Slug, is a key regulator of apoptosis in the response of early hematopoietic progenitors to gamma radiation. Enforced expression of miR-142 or miR-150 in normal mouse mammary stem cells resulted in the regeneration of hyperproliferative mammary glands in vivo. KrasG12D -independent tumor cells show a strong mesenchymal profile with active RAS-RAF-MEK-ERK (MAPK/ERK) signaling. Okamoto, T., Reitz, M. S., Clarke, M. F., JAGODZINSKI, L. J., WONGSTAAL, F. Sequence-specific interaction of histones with the simian virus 40 enhancer region in vitro. The SUVlean of residual viable tumors (4.51 +/- 1.34 [mean +/- SD]) was higher than that of mature teratoma (1.38 +/- 0.71) and necrosis or scar (1.05 +/- 0.29) (P < .05). He had office hours every day and heavily cared for your well-being. [2] We identify two distinct super-enhancers (SEs) associated with CD47 in certain cancer cell types. The mammary epithelium undergoes several rounds of extensive proliferation during the female reproductive cycle. 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. The conditional expression of lethal genes in tumor cells is a promising gene therapy approach for the treatment of cancer. This study demonstrates that combining global gene expression analysis with detailed annotated pathway resources applied to highly enriched normal and malignant stem cell populations, can yield an understanding of the critical pathways regulating cancer stem cells. His course "Justice" is the first Harvard course to be made freely available online and on television. These results indicate that addition of combinations of hematopoietic CSFs, together with a rapid medium exchange rate, can provide culture conditions that are suitable for the expansion of the progenitor cell pool and perhaps for the increased survival of hematopoietic stem cells in culture. He was on the senior staff of the S Herrema I, Clarke M. Anaesthesia for retinoblastoma screening - a dilemma. This new model for cancer will have significant ramifications for the way we study and treat cancer. Cancer stem cells are a minor population of tumor cells that possess the stem cell property of self-renewal. Professor Clarke is a former Deputy Vice . The possible significance of this finding is discussed. 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. Recently, his group described a molecular mechanism that confers resistance to radiation in breast cancer stem cells. The telomerase reverse transcriptase (TERT) promoter and the E2F-1 promoter are preferentially activated in cancer cells.

Under these conditions, the cultures produced as many cells as were inoculated every 2 weeks and led to a greater than 2.5-fold expansion in terms of the number of nonadherent cells produced over a 6- to 8-week period. For more information, please contact Ruth Lira, 650-723-1367. Michael Clarke was the original drummer of the Byrds, appearing on their first five albums before leaving around the end of 1967.Clarke was the least talented of the five members that were on the Byrds' 1965-1967 recordings, as unlike the others as could be, since he did almost no songwriting. This observation is traditionally explained by postulating variations in tumor microenvironment and coexistence of multiple genetic subclones, created by progressive and divergent accumulation of independent somatic mutations. However, the underlying molecular mechanisms are poorly characterized. Human breast tumors contain a breast cancer stem cell (BCSC) population with properties reminiscent of normal stem cells. 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. BMI1 has been demonstrated to play a role in self-renewal in other stem cell types and to be involved in tumorigenesis. James H. Clarke, Michael P. Vandenbergh . Two cDNA clones of the human c-myb gene have been isolated from a CCRF-CEM leukemia cell cDNA library and sequenced in their entirety. Zabala, M., Lobo, N. A., Seoane, J. This problem can be addressed by allowing limited viral replication. Epithelial-to-mesenchymal transition has been shown to correlate with therapy resistance, but the functional link and signalling pathways remain to be elucidated. Breast cancers contain a minority population of cancer cells characterized by CD44 expression but low or undetectable levels of CD24 (CD44+CD24-/low) that have higher tumorigenic capacity than other subtypes of cancer cells.We compared the gene-expression profile of CD44+CD24-/low tumorigenic breast-cancer cells with that of normal breast epithelium. In contrast, BMP7, a NODAL antagonist with context-dependent functions, is produced by basal cells and restrains progenitor cell proliferation. Since stromal cells in traditional human bone marrow cultures produce little HGFs, we have begun by asking whether local supplementation of hematopoietic growth factors via genetically engineered stromal cells might augment hematopoiesis in liquid cultures. Wu, A. R., Neff, N. F., Kalisky, T., Dalerba, P., Treutlein, B., Rothenberg, M. E., Mburu, F. M., Mantalas, G. L., Sim, S., Clarke, M. F., Quake, S. R. Oncogenic miRNAs and the perils of losing control of a stem cell's epigenetic identity. In contrast, AdEHE2F was attenuated in nontransformed quiescent cells growing under normoxic conditions, suggesting that an intact pRB pathway with low levels of E2F transcription factors acts as a negative modulator for the virus. 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. Amy Smith Berylson Professor of Materials Science and Professor of Chemistry & Chemical Biology. In this report, we analyzed the possible existence of cis-acting sequences involved in intracellular trafficking of the p53 protein. Bcl11b maintains the long-term mammary stem cell and is crucial for drug resistance in breast cancer. Self-renewal requires the integration of survival signals and proliferation controls with the maintenance of an undifferentiated state. Finally, questions regarding p53 cellular trafficking will also be discussed. As precision medicine increases the response rate of treatment, tumors frequently bypass inhibition and reoccur. bcl-x is a member of the bcl-2 family of genes and by alternative splicing gives rise to two distinct mRNAs: bcl-xL and bcl-xS. Here we investigate the roles of these three proteins in the regulation of self-renewal and proliferation of mammary epithelial cells. Yoo, S., Chandhasin, C., Del Rosario, J. R., Chen, Y. K., Stafford, J., Quake, S., Perabo, F., Clarke, M. F. Pharmacologic characterization of TACH101, a first-in-class KDM4 inhibitor for development as a cancer therapeutic. 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). Akala, O. O., Park, I., Qian, D., Pihalja, M., Becker, M. W., Clarke, M. F. A gene signature in breast cancer - Reply. These results suggest that Bcl-2 family members are required for survival of cancer cells derived from solid tissues. Three well-known tumor suppressors, p53, p16INK4a, and p19ARF, have been connected to the limiting of stem cell self-renewal and proliferation. View details for Web of Science ID A1991GV58400008. We developed a new technique that replaces immunoprecipitation with a simplified chromatin fragmentation and proximity ligation step that eliminates bead purification and washing steps. Results The transcription factor CDX2 ranked first in our screening test. 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. The tumorigenic subpopulation could be serially passaged: each time cells within this population generated new tumors containing additional CD44(+)CD24(-/low)Lineage(-) tumorigenic cells as well as the phenotypically diverse mixed populations of nontumorigenic cells present in the initial tumor.

MACARTHUR, L. H., Clarke, M. F., Westin, E. H. THE INFLUENCE OF EXTRACELLULAR-MATRIX AND STROMA REMODELING ON THE PRODUCTIVITY OF LONG-TERM HUMAN BONE-MARROW CULTURES. Michael Clarke Duncan was born on December 10, 1957 in Chicago, Illinois. View details for Web of Science ID A1991EY27300001. Disease status (no. The arrangement of this clone suggests that its RNA transcript was activated by provirus integration in cis, possibly by the activity of a downstream provirus enhancer. However, to date, genetic modification of the human hematopoietic stem cell has been relatively inefficient. Adjunct Professor Michael Whitehouse. Here we show that in Ts65Dn mice, which are trisomic for 132 genes homologous to genes on human chromosome 21, triplication of Usp16 reduces the self-renewal of haematopoietic stem cells and the expansion of mammary epithelial cells, neural progenitors and fibroblasts. Mandel, Michael - Associate Professor: Computer and Information Science Manlow, Veronica B. Analysis of DNase I cutting of uniquely end-labeled complexes suggests that the fragment containing a single 72-bp element forms a positioned core particle. U.S.A. 1995;92:11024-11028) is used in combination with Ad5ERE2, the ability of both viruses to induce cell death is dramatically increased, and the effect can be modulated by addition of the antiestrogen tamoxifen. High-dose chemotherapy (HDCT) and autologous bone marrow transplantation (BMT) is frequently used to treat patients with metastatic cancer including breast cancer and neuroblastoma. While the majority of the cancer cells have a limited ability to divide, a population of cancer stem cells that has the exclusive ability to extensively proliferate and form new tumors can be identified based on marker expression. Thus understanding the mechanisms that regulate stem cell generation has implications for normal development and disease. Traditional methods of implementing this assay are lengthy, cumbersome and require a large number of cells, making it difficult to study rare cell types such as certain cancer and stem cells. Bcl-2 prevented radiation-induced cell death in DP16-1 cells expressing wtp53 and delayed radiation-induced cell death in DP16-1 cells without wtp53. Here we present a compendium of single-cell transcriptomic data from the model organism Mus musculus that comprises more than 100,000 cells from 20 organs and tissues. Finally, we show how gene expression shifts in distinct tissues are highly correlated with corresponding protein levels in plasma, thus potentially contributing to the ageing of the systemic circulation. Frequently, overexpression of a member of the Bcl-2 family results in a block in cell death and appears to nullify many built-in cellular defense mechanisms against cancer. Although the colon also contains Lgr5(+) stem cells, it does not contain Paneth cells. The successful ex vivo reconstruction of human bone marrow is an extraordinarily important basic scientific and clinical goal. Single cell transcriptomics is revolutionising our understanding of tissue and disease heterogeneity, yet cell type identification remains a partially manual task. Overall, we demonstrate a novel approach for imaging physiologic and pathological remodeling. Data from individual tumor phenotypic analysis and serial transplants performed in limiting dilution show that residual tumors are enriched for cells with the CoCSC phenotype and have increased tumorigenic cell frequency. The blocking effect of the CSD is not due to the enhancement of nuclear export or oligomerization of the p53. These data, taken together with similar findings with other human neoplasms, show that CD47 is a commonly expressed molecule on all cancers, its function to block phagocytosis is known, and blockade of its function leads to tumor cell phagocytosis and elimination. (2010) dissect the gene expression signature of ES cells into three functional modules and find that the Myc module, including genes targeted by Myc-interacting proteins, accounts for most of the similarity between ES and cancer cells. Estrogen response elements and hypoxia-responsive elements were combined to activate transcription in cells that present at least one of these characteristics. View details for DOI 10.1016/j.stemcr.2020.12.012. Disclosure of potential conflicts of interest is found at the end of this article. 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). Despite this central role, the mechanism of action of Bcl-2 is not yet clear. Wild-type p53 plays a crucial role in the control of apoptosis following ionizing radiation (IR); conversely, mutant p53 is associated with IR resistance. Michael Sandel teaches political philosophy at Harvard University. Liu, T. X., Becker, M. W., Jelinek, J., Wu, W., Deng, M., Mikhalkevich, N., Hsu, K., Bloomfield, C. D., Stone, R. M., DeAngelo, D. J., Galinsky, I. This cell line contains a wild-type p53 gene and is an ideal model for studying the mechanism of IR resistance in this disease. AKR/J mice had significantly higher frequencies and numbers of both HSCs and restricted progenitors in their bone marrow than C57BL/Ka-Thy-1.1 mice. View details for Web of Science ID A1996WD32200005. The Weight can be changed regularly, here we have added the latest value. Other pathways have not been previously implicated in the regulation of cancer stem cell functions, including Ribosome and T Cell Receptor Signaling pathway. . Cai, S., Kalisky, T., Dalerba, P., Clarke, M., Stanford Univ. Liu, H., Bockhorn, J., Dalton, R., Nwachukwu, C., Prat, A., Yee, K., Huang, S., Swanson, K., Perou, C. M., Olopade, O. I., Clarke, M. F., Greene, G. L. MicroRNA-203 restricts the proliferation capacity of normal colon and colon cancer stem cells by regulating the expression of Tcf4. The IGS was also associated with the prognosis in medulloblastoma (P=0.004), lung cancer (P=0.03), and prostate cancer (P=0.01). View details for DOI 10.1073/pnas.0610117104, View details for Web of Science ID 000243761100053. Cells that expressed kappa- or lambda-light chains were separated by cell sorting from kappa- or lambda-negative cells and replaced in culture. Poorly regulated tissue remodeling results in increased breast cancer risk, yet how breast cancer stem cells (CSC) participate in remodeling is unknown. View details for Web of Science ID 000316614600063. Limiting dilution transplantations of breast epithelial cells devoid of TLR2 or MYD88 revealed a significant decrease in mammary repopulating unit frequency compared with the control. Thus a limiting serum component is responsible for the altered metabolic and growth rates. The ability to slow or reverse biological ageing would have major implications for mitigating disease risk and maintaining vitality1. We prospectively identified and isolated the tumorigenic cells as CD44(+)CD24(-/low)Lineage(-) in eight of nine patients. erenakgun@g.harvard.edu. 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. Single-cell RNA sequencing (scRNA-seq) is a powerful approach for reconstructing cellular differentiation trajectories. Liu, H., Bockhorn, J., Dalton, R., Chang, Y., Qian, D., Zitzow, L. A., Clarke, M. F., Greene, G. L. Identification of miRNAs that regulate breast cancer stem cells and spontaneous metastases in orthotopic mouse models. Dole, M. G., Clarke, M.
