We have developed a strategy of limited viral replication using AdRSVlaclys, a chemically modified E1-deleted adenovirus, to codeliver an exogenous plasmid encoding the adenovirus E1 region. Although neither the visual interpretation nor SUVlean differentiated mature teratoma from necrosis or scar, there were statistically significant differences in the kinetic rate constants K1 and K between mature teratoma and necrosis or scar as follows: K1, 0.113 mL/min/g +/- 0.026 versus 0.036 mL/min/g +/- 0.005 (P < .05); K, 0.005 mL/min/g +/- 0.003 versus 0.0008 mL/min/g +/- 0.0001 (P < .05).FDG PET with kinetic analysis appears to be a promising method for management of disease in patients with GCT after treatment. The Leopard 2 tanks are what the Ukrainians really need, more than the Challenger 2 and Abrams tanks, Clarke argued. 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. In back-to-back articles in Cell and Cell Stem Cell, Song etal. Treatment-related mortality was 10%. We have previously shown that constitutive expression of c-myb blocks differentiation. The median PFS and OS for the whole group are 4 and 14 months, respectively. Olivieri, J., Dehghannasiri, R., Wang, P. L., Jang, S., de Morree, A., Tan, S. Y., Ming, J., Wu, A., Consortium, T., Quake, S. R., Krasnow, M. A., Salzman, J. TACH101, a first-in-class pan inhibitor of KDM4 histone lysine demethylases. This new model for cancer will have significant ramifications for the way we study and treat cancer. Alzheimer's disease (AD) is a progressive neurodegenerative disease observed with aging that represents the most common form of dementia. Abnormal p53 cellular localization has been considered to be one of the mechanisms that could inactivate p53 function. Parks, I. K., Klug, C. A., Li, K. J., Jerabek, L., Li, L. H., Nanamori, M., Neubig, R. R., Hood, L., Weissman, I. L., Clarke, M. F. A novel, conditionally replicative adenovirus for the treatment of breast cancer that allows controlled replication of E1a-deleted adenoviral vectors. Identification of pancreatic cancer stem cells and further elucidation of the signaling pathways that regulate their growth and survival may provide novel therapeutic approaches to treat pancreatic cancer, which is notoriously resistant to standard chemotherapy and radiation. 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. BACKGROUND: Recent studies in murine mammary tissue have identified functionally distinct cell populations that may be isolated by surface phenotype or lineage tracing. These findings have implications for the development of effective therapeutic agents targeting tumor-initiating cells. Using this system, we have generated AdEHT2 and AdEHE2F, two conditionally replicative adenoviruses for the treatment of breast cancer. Sikandar, S. S., Kuo, A. H., Kalisky, T. n., Cai, S. n., Zabala, M. n., Hsieh, R. W., Lobo, N. A., Scheeren, F. A., Sim, S. n., Qian, D. n., Dirbas, F. M., Somlo, G. n., Quake, S. R., Clarke, M. F. Control of inflammation by stromal Hedgehog pathway activation restrains colitis. Ailles, L., Prince, M., Joshua, B., Doweck, I., Kaplan, M., Clarke, M., Weissman, I. (2007) analyze the relationship between CSC and tumor metastasis. Adjunct Associate Professor Jon Womersley. Following high-dose IR, cell fractionation demonstrated that p53 is induced and targeted to the nucleus.

We review the biological basis and the therapeutic implications of the stem cell model of cancer. Publications Journal Articles (89) Conference Papers (5) Journal Articles Clarke, Paul R. (2021). We found 37 microRNAs that were differentially expressed between human BCSCs and nontumorigenic cancer cells. We discuss possible functional consequences of such nucleosome positioning. Disclosure of potential conflicts of interest is found at the end of this article. Furthermore, we found that the c-myc and bcl-2 genes cooperate to inhibit p53 functions.

Cancers arise in a tissue as the culmination of a series of mutations that activate oncogenes and inactivate tumor suppressor genes. However, deletions of more than two amino acids between this region abolished the transport of p53 into the nucleus. Estrogen response elements and hypoxia-responsive elements were combined to activate transcription in cells that present at least one of these characteristics. Purging of autologous stem cell sources with bcl-x(s) adenovirus for women undergoing high-dose chemotherapy for stage IV breast carcinoma. We found cell-specific changes occurring across multiple cell types and organs, as well as age-related changes in the cellular composition of different organs. F-MEL clones expressing the highest levels of the human c-myb mRNA differentiate poorly in response to dimethyl sulfoxide. ANGELOTTI, T. P., Clarke, M. F., Longino, M. A., Emerson, S. G. THE CONSTRUCTION OF HIGH-EFFICIENCY HUMAN BONE-MARROW TISSUE EXVIVO. We have studied the ability of c-myc and bcl-2 oncogenes to modulate p53 function. Stem cells persist throughout life by self-renewing in numerous tissues including the central and peripheral nervous systems. Four major epithelial subtypes or transcriptional states were revealed by gene expression analysis of selected populations of single cells. This is an overview of the elements and molecules involved in p53 nucleocytoplasmic transportation. The wild-type p53/GFP fusion protein was localized in the cytoplasm, the nucleus, or both compartments in a subset of the cells.

One of the best candidate genes involved in conferring self-renewal capacity is Bmi-1, which has been proven to be essential for the maintenance of both normal adult hematopoietic and leukemia stem cells, as well as adult neural stem cells. 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. The conditional expression of lethal genes in tumor cells is a promising gene therapy approach for the treatment of cancer. Acad. Three seminoma patients remain progression-free. While the class is nonetheless challenging, Professor Clark does his best to help all students pass. Reinitz, F., Chen, E. Y., Nicolis di Robilant, B., Chuluun, B., Antony, J., Jones, R. C., Gubbi, N., Lee, K., Ho, W. H., Kolluru, S. S., Qian, D., Adorno, M., Piltti, K., Anderson, A., Monje, M., Heller, H. C., Quake, S. R., Clarke, M. F. LEFTY1 Is a Dual-SMAD Inhibitor that Promotes Mammary Progenitor Growth and Tumorigenesis. The simulation demonstrates that removal of stem cells is a possible mechanism leading to culture decline. (2002) demonstrate that the CED-1 homolog, Slug, is a key regulator of apoptosis in the response of early hematopoietic progenitors to gamma radiation. Clarke, M. F., KukowskaLatallo, J. F., Westin, E., Smith, M., Prochownik, E. V. ACTIVATION OF A NOVEL KPNI TRANSCRIPT BY DOWNSTREAM INTEGRATION OF A HUMAN T-LYMPHOTROPIC VIRUS TYPE-I PROVIRUS. However, to date, genetic modification of the human hematopoietic stem cell has been relatively inefficient. BMI1 has been demonstrated to play a role in self-renewal in other stem cell types and to be involved in tumorigenesis. Flow cytometry and microfluidics-based single-cell multiplex RT-PCR allowed dissection of IFN responses in single RV-infected and bystander intestinal epithelial cells (IECs). Pagination. Notably, these gene sets show similar expression across tissues, differing only in the amplitude and the age of onset of expression. These results suggest that inhibitors of the TLR2 pathway merit investigation as possible therapeutic and chemoprevention agents. In this study, we report that miR-142 efficiently recruits the APC mRNA to an RNA-induced silencing complex, activates the canonical WNT signaling pathway in an APC-suppression dependent manner, and activates the expression of miR-150. Here we show that Bmi-1 is required for the self-renewal of stem cells in the peripheral and central nervous systems but not for their survival or differentiation. RRV replication was significantly rescued in IFN types I and II, as well as STAT1 (IFN types I, II, and III) deficient mice in contrast to EW, which was only modestly sensitive to IFNs I and II. PHD Student in Computer Science. To delineate more accurately the point at which Myb blocks differentiation, MEL cells were transfected with a human c-myb construct under the control of the beta-globin promoter and enhancers. To gain a better insight into these processes, here we generate a single-cell transcriptomic atlas across the lifespan of Mus musculus that includes data from 23 tissues and organs. 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. The complexity and inefficiency of chromatin immunoprecipitation strategies restrict their sensitivity and application when examining rare cell populations. Three of these forms co-migrate on Northern blots and are co-expressed in several human hematopoietic cell types. In order for treatment to be effective long term, the mechanisms enabling treatment adaptation need to be understood. Both fragments formed complexes with electrophoretic mobilities of nucleosomes containing the appropriate length of DNA. Palovics, R., Keller, A., Schaum, N., Tan, W., Fehlmann, T., Borja, M., Kern, F., Bonanno, L., Calcuttawala, K., Webber, J., McGeever, A., Tabula Muris Consortium, Luo, J., Pisco, A. O., Karkanias, J., Neff, N. F., Darmanis, S., Quake, S. R., Wyss-Coray, T., Almanzar, N., Antony, J., Baghel, A. S., Bakerman, I., Bansal, I., Barres, B. 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. Tel: +44 (0)131 650 4327. This finding suggests a mechanism by which normal hematopoietic progenitors can survive and proliferate despite p53 expression and by which the inappropriate expression of bcl-2 and c-myc can cooperate in transformation. It has been viewed by tens of millions of people around the world, including in China, where Sandel was named the "most . Ealovega, M. W., McGinnis, P. K., Sumantran, V. N., Clarke, M. F., Wicha, M. S. A RECOMBINANT BCL-X(S) ADENOVIRUS SELECTIVELY INDUCES APOPTOSIS IN CANCER-CELLS BUT NOT IN NORMAL BONE-MARROW CELLS. These studies suggest that adenovirus suicide vectors may provide a simple and effective method to selectively eliminate cancer cells derived from epithelial tissue that contaminate bone marrow to be used for autologous BMT. Programmed cell death (PCD) plays an important role in normal and malignant hematopoieis. 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+"). Michael Clark. Ageing is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death1. 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. Amy Smith Berylson Professor of Materials Science and Professor of Chemistry & Chemical Biology. 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. We used a replication-deficient adenoviral vector to transiently overexpress Bcl-xs in MCF-7 human breast cancer cells, which overexpress Bcl-xL. Thus a limiting serum component is responsible for the altered metabolic and growth rates. Professor Michael Clarke write a piece in The Sun saying time was running out for Putin. Just months into the Biden-Harris administration, the change in tone, message, and approach to transatlantic relations is palpable. A subpopulation of tumor cells, termed cancer stem cells (CSC), appears uniquely able to fuel the growth of phenotypically and histologically diverse tumors. 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. 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. School of Civil Engineering +61 7 336 56464. william.clarke@uq.edu.au. To explore the possible role of c-sis expression in HTLV-induced disease, we have obtained cDNA clones of c-sis from HUT-102 cells. The mammary epithelium undergoes several rounds of extensive proliferation during the female reproductive cycle. The United States has always regarded certainly jihadist terrorism . Epithelial-to-mesenchymal transition has been shown to correlate with therapy resistance, but the functional link and signalling pathways remain to be elucidated. G1 arrest at 37.5 degrees C, utilizing either mimosine or isoleucine deprivation, does not lead to rapid cell death. Heights. Willingham, S. B., Volkmer, J., Gentles, A. J., Sahoo, D., Dalerba, P., Mitra, S. S., Wang, J., Contreras-Trujillo, H., Martin, R., Cohen, J. D., Lovelace, P., Scheeren, F. A., Chao, M. P., Weiskopf, K., Tang, C., Volkmer, A. K., Naik, T.

O., Steinberg, G. K., Li, G., So, S. K., Majeti, R., Harsh, G. R., van de Rijn, M., Teng, N. N., Sunwoo, J. 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. The Bcl-2 protein inhibits apoptosis induced by a variety of signals, in a range of cell types and in diverse organisms, and it is implicated in both normal development and oncogenesis. Although a major commonly deleted region (CDR) has been delineated on chromosome band 5q31.1 (refs. Because of the unusual findings of apparently inappropriate HLA antigens in HTLV infected cells, we had previously looked for rearrangement of class I-related genes in HTLV infected cells but failed to find any. We have examined the effects of conditionally expressing wild-type p53 activity in HT29 cells on DNA damage and cytotoxicity caused by exposure to fluorodeoxyuridine (FdUrd). Increased levels of c-sis cDNA expression correlated with the acquisition of features of transformation in a dose-dependent manner and altered the cellular phenotype in a manner consistent with the progression of cells towards malignancy. Clarke, M. F., Clevers, H., Eaves, C. J., Weinberg, R. A., Rajasekhar, V. K. Quantitative assessment of single-cell RNA-sequencing methods. With the growing evidence that cancer stem cells exist in a wide array of tumors, it is becoming increasingly important to understand the molecular mechanisms that regulate self-renewal and differentiation because corruption of genes involved in these pathways likely participates in tumor growth. The Department of Adolescent and Young Adult Medicine's multidisciplinary team includes adolescent physicians, clinical nurse consultant, social worker, clinical psychologist, occupational therapist, dietitian and experienced ward nurses.

This study reports that fluorescence-activated cell sorting (FACS) is a simple and efficient approach for purifying living primary human breast tumor cells from LDV(+) mouse stromal cells, which can be completed in a few hours. They discuss the increasing threat of China, the post-Brexit identity of "Global Britain" and how the . Bcl11b(high) cells are enriched for cells that can regenerate mammary glands in secondary transplants. New treatment modalities are needed for the latter group. Replication-deficient viral vectors are currently being used in gene transfer strategies to treat cancer cells. 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. Jasty, R., Lu, J. Y., Irwin, T., Suchard, S., Clarke, M. F., Castle, V. P. Cooperation of a single lysine mutation and a C-terminal domain in the cytoplasmic sequestration of the p53 protein, A method of limited replication for the efficient in vivo delivery of adenovirus to cancer cells. 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. These data support a model in which low levels of sis gene expression in tumors contribute to the acquisition of some features of transformation but require complementation by other genes or factors to produce a fully malignant phenotype. Usp16 can remove ubiquitin from histone H2A on lysine 119, a critical mark for the maintenance of multiple somatic tissues. 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). By examining the pathways upstream and downstream of Bmi1, hence the molecular pathways that regulate self-renewal, his laboratory found that USP16, a protein that dampens Bmi1 signals, causes a stem cell defect in various stem cells in Downs syndrome, including neural stem cells. He has also acted as a reviewer for the EPSRC and for funding councils in Austria, Finland, France and Germany. The p53-dependent pathway results in cell death via apoptosis and occurs approximately 24 h following radiation. In the present study, further mutagenesis analyses were carried out between Lys-305 and the major nuclear localization signal (NLS I) of p53. In several forms of human cancer, only a phenotypic subset of cancer cells, usually termed "cancer stem cells" (CSC), can initiate tumor growth when transplanted. Immunohistochemistry revealed that the CD44(+) cancer cells have a primitive cellular morphology and costain with the basal cell marker Cytokeratin 5/14, whereas the CD44(-) cancer cells resemble differentiated squamous epithelium and express the differentiation marker Involucrin. Furthermore, we found that specifically inhibiting human DLL4 in the tumor, either alone or in combination with the chemotherapeutic agent irinotecan, reduced cancer stem cell frequency, as shown by flow cytometric and in vivo tumorigenicity studies. Rachel Ellehuus. The miR-30c-VIM/TWF1 signaling cascade is also associated with clinical outcome in breast cancer patients. Kohrt, H. E., Houot, R., Weiskopf, K., Goldstein, M., Lund, P., Scheeren, F., Czerwinski, D., Colevas, A. D., Weng, W., Clarke, M. F., Carlson, R. W., Sunwoo, J., Tedder, T., Chen, L., Levy, R. The CD47-signal regulatory protein alpha (SIRPa) interaction is a therapeutic target for human solid tumors. Akala, O. O., Park, I., Qian, D., Pihalja, M., Becker, M. W., Clarke, M. F. A gene signature in breast cancer - Reply. Enforced expression of miR-142 or miR-150 in normal mouse mammary stem cells resulted in the regeneration of hyperproliferative mammary glands in vivo. Our results indicate that Bmi-1 is essential for the generation of self-renewing adult HSCs. Zhao, C., Cai, S., Shin, K., Lim, A., Kalisky, T., Lu, W., Clarke, M. F., Beachy, P. A. We observed an almost universal loss of gene expression with age that is largely mimicked by parabiosis: aged blood reduces global gene expression, and young blood restores it in select cell types. Reduction of USP16 led to decreased expression of senescence gene Cdkn2a and mitigated aberrant regulation of the BMP pathway, a previously unknown function of USP16. 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. 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. 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. Constitutive expression of mbm2, in contrast to c-myb, here resulted in enhanced differentiation of F-MEL cells. 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. Patients with relapsed/ refractory testicular cancer benefit most from ABMT if they have platinum-sensitive disease in first relapse. 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. View details for Web of Science ID A1984TC73000037. Previous studies have shown that blocking DLL4 signaling reduced tumor growth by disrupting productive angiogenesis. The tumors in these tissues consist of heterogeneous populations of cancer cells that differ markedly in their ability to proliferate and form new tumors. 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. Prior to coming to UK, Dr. Clark was the Chief Economist for the Kentucky Legislative Research . View details for Web of Science ID 000178077600006. Chromatin immunoprecipitation (ChIP) is a powerful assay used to probe DNA-protein interactions. At the time of ABMT, 10 were chemosensitive, four were chemoresistant, and 10 were absolutely refractory to platinum. NB cells showed loss of viability with both viruses, although the bcl-xS virus was most toxic. The results demonstrate that cell sorting is effective, much faster and less likely to alter tumor cell phenotype than traditional methods for removing LDV from xenograft models. Sufficient new cells have to be produced to maintain the integrity of a tissue, but excessive proliferation resulting in tumorigenesis needs to be prevented. However, inferring both the state and direction of differentiation is challenging. The Thy-1+CD24medCD49fhigh phenotype contained the majority of the serially transplantable epithelial cells. Finally we report that the TNF-NFKB1 signalling pathway directly regulates CD47 by interacting with a constituent enhancer located within a CD47-associated SE specific to breast cancer. Here we show that the short half-lives of retroviruses limit the distance that they can effectively travel in solution by Brownian motion, and thus the possibility of successful gene transfer.

Such cells do not express beta-galactosidase, indicating that hematopoietic stem cells do not express transgene encoded by adenovirus vectors based upon the RSV-AD5 vector system. This genetic signature of tumorigenic breast-cancer cells was even more strongly associated with clinical outcomes when combined with the WR signature in breast cancer.

His group was the first to discover that the proto-oncogene Bmi-1 regulates stem cell self-renewal via an epigenetic mechanism. Stimulation of trastuzumab-activated human NK cells with an agonistic mAb specific for CD137 killed breast cancer cells (including an intrinsically trastuzumab-resistant cell line) more efficiently both in vitro and in vivo in xenotransplant models of human breast cancer, including one using a human primary breast tumor. He has been a member of the AHRC Peer Review College and a Strategic Reviewer for the AHRC. The height of Michael Clarke is in centimeters- 165 cm in meters- 1.65 m in Feet Inches- 5' 5". Results The transcription factor CDX2 ranked first in our screening test. View details for Web of Science ID 000168968300004. 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. However, the mechanisms regulating p53 subcellular localization remain unclear. Thus, these mice allow for the isolation of viable Bmi-1-expressing cells and have the potential to become a useful tool for understanding the role of Bmi-1 in normal and cancer stem cells in multiple tissue types. 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. These results suggest that radiation-induced cell death occurs by both p53-dependent and p53-independent pathways. The possible significance of this finding is discussed. These findings have important implications for the development and evaluation of oncologic therapies and present opportunities for potential gains in patient outcome. Discover Michael Clarke 's Biography, Age, Height, Physical Stats, Dating/Affairs, Family and career updates. Molofsky, A. V., Pardal, R., Iwashita, T., Park, I. K., Clarke, M. F., Morrison, S. J. Bmi-1 is required for maintenance of adult self-renewing hematopoietic stem cells. 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. 37.5 degrees C, utilizing either mimosine or isoleucine deprivation, does lead.
