These results suggest that LEFTY1 is an endogenous dual-SMAD inhibitor and that suppressing its function may represent a therapeutic vulnerability in breast cancer. This antigen may account for the extra HLA-A and -B specificities detected in HTLV-infected cells using alloantisera. Southern blots of DNA from HTLV-infected cells digested with the methylation-sensitive restriction enzyme HpaII showed that the proviral DNA was methylated in all of the uncultured peripheral blood cells tested. Recently, we have found that a recombinant adenovirus vector that contains a bcl-x, minigene (a dominant negative inhibitor of the bcl-2 family), called the bcl-x(s) adenovirus, is lethal to cancer cells derived from epithelial tissues, but not to normal human hematopoietic cells. Finally, the laboratory is actively pursuing how cancer stem cells self-renew to maintain themselves and escape the genetic constraints on unlimited self-renewal that regulate normal stem cell numbers. These sequences, when compared with those previously reported for the human c-myb gene, reveal an alternative splicing process that generates at least four forms of the c-myb message.

Data on sequence comparisons with mouse and chicken homologues of c-myb coupled with oligonucleotide hybridization to genomic clones of the human c-myb gene indicate that this alternative splicing process utilizes three closely spaced splice donor sites and two unique exons present between viral defined exons 5 and 6. Our study identifies both epithelial-mesenchymal transition (EMT) and active MAPK/ERK signaling in tumors that adapt to oncogenic KrasG12D withdrawal in a novel Trp53-/- breast cancer mouse model. [2] Usp16 contributes to somatic stem-cell defects in Down's syndrome. First, we quantitatively imaged physiologic remodeling of primary branches of the developing and regenerating mammary tree. Within 24-48 hr, viral RNA expression increased at least four- to eightfold. This phenotypic diversity is driven by a small subset of mammary tumour stem cells. Using a xenograft model in which primary human pancreatic adenocarcinomas were grown in immunocompromised mice, we identified a highly tumorigenic subpopulation of pancreatic cancer cells expressing the cell surface markers CD44, CD24, and epithelial-specific antigen (ESA). Zhao, C., Cai, S., Shin, K., Lim, A., Kalisky, T., Lu, W., Clarke, M. F., Beachy, P. A. The telomerase reverse transcriptase (TERT) promoter and the E2F-1 promoter are preferentially activated in cancer cells. Our study demonstrates that microRNA-30c is transcriptionally regulated by GATA3 in breast tumours. Results The transcription factor CDX2 ranked first in our screening test. Here, we identify a quiescent mammary epithelial cell population expressing high levels of Bcl11b and located at the interface between luminal and basal cells. We found that adult and fetal mouse and adult human HSCs express the proto-oncogene Bmi-1. 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. Previous studies have shown that blocking DLL4 signaling reduced tumor growth by disrupting productive angiogenesis. Using in vivo lineage tracing and triple negative breast cancer (TNBC) patient derived xenografts we demonstrate that the repopulating capacity in normal mammary epithelial cells and tumorigenic capacity in TNBC is independent of expression of EMT-associated genes. Professor Clark is someone that should teach all students. Facebook gives people the power. The simulation demonstrates that removal of stem cells is a possible mechanism leading to culture decline. From 1990 to 2001 he was the founding Director of the Centre for Defence Studies at King's. We proposed that epithelial tissue stem cells and their cancer stem cell (CSC) counterparts may also share this property. James H. Clarke, Michael P. Vandenbergh . Professor Michael Clarke was Director-General of the Royal United Services Institute (RUSI) from 2007 to 2015 when he retired from that role. Inhibiting USP16 rescues stem cell aging and memory in an Alzheimer's model. Some mice were given the RTK inhibitor imatinib after injection of cancer cells; tumor growth was measured based on bioluminescence. Down's syndrome results from full or partial trisomy of chromosome 21. In bone marrow, RGS18 level is highest in long-term and short-term hematopoietic stem cells, and is decreased as they differentiate into more committed multiple progenitors. Ailles, L., Prince, M., Joshua, B., Doweck, I., Kaplan, M., Clarke, M., Weissman, I. Cell migration is an essential component of almost every step of the metastatic cascade, especially the early step of invasion inside the primary tumor. Therefore, functional inhibition of Bcl-2 family members is lethal to many cancer cells. Therefore, senescence of stem cells must be prevented. [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. Cancer stem cells are a minor population of tumor cells that possess the stem cell property of self-renewal.

Human breast tumors contain a breast cancer stem cell (BCSC) population with properties reminiscent of normal stem cells. The data are consistent with formation of a core particle on one or the other of the repeated enhancer sequences. 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. Treatment with anti-human DLL4 inhibited the expression of Notch target genes and reduced proliferation of tumor cells. Herrema I, Clarke M. Anaesthesia for retinoblastoma screening - a dilemma. 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. The main focus of this review is the role of mammary stem cells in normal breast development and carcinogenesis. Fifteen (52%) received both transplants.

The possible significance of this finding is discussed. DNA fragments containing either one or both of the 72-base pair (bp) elements which constitute the SV40 enhancer and the three adjacent 21-bp repeats were associated with histone octomers from chicken erythrocytes in vitro. To test this hypothesis, murine erythroleukemia cells were transfected with bcl-XL and p53ts. Office Hours: Tuesday 12:00-1:00PM; Thursday 2:00-3:00PM; Friday 10:30-11:30AM. miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway. Replication-defective retroviruses are frequently used as gene carriers for gene transfer into target cells. The molecular mechanisms that control the self-renewal of HSCs are still largely unknown. We developed an immunodeficient mouse model to test the tumorigenic potential of different populations of cancer cells derived from primary, unmanipulated human HNSCC samples.

Prevention of fluorodeoxyuridine-induced cytotoxicity and DNA damage in HT29 colon carcinoma cells by conditional expression of wild-type p53 phenotype. The telomerase core promoter failed to block the replication of the virus in telomerase-negative cells. Clarke, M. F., Gelmann, E. P., Reitz, M. S. RELATION OF RESPIRATORY BURST AND ARACHIDONATE METABOLISM DURING PHAGOCYTOSIS BY GUINEA-PIG ALVEOLAR MACROPHAGES. To examine the influence of stromal cell layer aging, conditioned medium was obtained from the first two weeks of LTHBMCs that was subsequently concentrated and used as a medium supplement in a second set of slowly exchanged LTHBMCs. Hematopoietic cells exposed to the suicide vectors were able to reconstitute the bone marrow of mice exposed to lethal doses of y-irradiation. Varma, A., ELAWAR, F. Y., Palsson, B. O., Emerson, S. G., Clarke, M. F. MALIGNANT TRANSFORMATION OF NIH 3T3 FIBROBLASTS BY HUMAN C-SIS IS DEPENDENT UPON THE LEVEL OF ONCOGENE EXPRESSION. 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. Transformation is a complex cellular process that requires several genetic abnormalities. We used xenograft tumors of MDA-MB-231 cells as well as a low passage xenograft tumor from orthotopically injected patient-derived breast tumor cells. The weight is in Kilograms- 70 kg. 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. Bockhorn, J., Yee, K., Chang, Y., Prat, A., Huo, D., Nwachukwu, C., Dalton, R., Huang, S., Swanson, K. E., Perou, C. M., Olopade, O. I., Clarke, M. F., Greene, G. L., Liu, H. Innate immune response to homologous rotavirus infection in the small intestinal villous epithelium at single-cell resolution.

Ad5ERE2 is able to kill ER(+) human breast cancer cell lines as efficiently as the wild-type virus, but has decreased capacity to affect ER(-) cells. Cai, S., Kalisky, T., Sahoo, D., Dalerba, P., Feng, W., Lin, Y., Qian, D., Kong, A., Yu, J., Wang, F., Chen, E. Y., Scheeren, F. A., Kuo, A. H., Sikandar, S. S., Hisamori, S., van Weele, L. J., Heiser, D., Sim, S., Lam, J., Quake, S., Clarke, M. F. Targeted chromatin ligation, a robust epigenetic profiling technique for small cell numbers. However, to date, genetic modification of the human hematopoietic stem cell has been relatively inefficient. This suggests RGS18 can act on G(q)-mediated signaling pathways in vivo. 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. 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. 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. 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. 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. Finally, we show evidence that these properties are maintained in the context of an adenoviral vector (AdEHhrk). Ageing is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death1. B-cell lines established from two individuals with T-cell acute lymphocytic leukemia (T-ALL) express HLA-DR antigens, whereas the isogenic T-cells do not. A central issue in stem cell biology is to understand the mechanisms that regulate the self-renewal of haematopoietic stem cells (HSCs), which are required for haematopoiesis to persist for the lifetime of the animal. In some cancer cells, the process of self-renewal is de-regulated resulting in expansion of these cells and tumors. Prior to coming to UK, Dr. Clark was the Chief Economist for the Kentucky Legislative Research . ANGELOTTI, T. P., Clarke, M. F., Longino, M. A., Emerson, S. G.

View details for Web of Science ID A1984SV56900010. G418-resistant clones, which expressed the c-sis cDNA, were selected and characterized. 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 inhibitors of the TLR2 pathway merit investigation as possible therapeutic and chemoprevention agents. Together, these data lay the groundwork for a systemic understanding of the interplay between blood-borne factors and cellular integrity. Mutagenesis analysis demonstrated that a single amino acid mutation of Lys-305 (mt p53) caused cytoplasmic sequestration of the p53 protein in the MCF-7 and RKO cells, whereas the fusion protein was distributed in both the cytoplasm and the nucleus of SAOS-2 cells. The enhanced ability of CD44(+)CD24(+)ESA(+) pancreatic cancer cells to form tumors was confirmed in an orthotopic pancreatic tail injection model. Josephs, S. F., Ratner, L., Clarke, M. F., Westin, E. H., Reitz, M. S., WONGSTAAL, F. DIFFERENTIAL METHYLATION OF CLASS-I HISTOCOMPATIBILITY ANTIGEN GENES IN T-CELL LINES DERIVED FROM TWO DIFFERENT TYPES OF T-CELL MALIGNANCIES, TRANSFORMATION OF NIH 3T3-CELLS BY A HUMAN C-SIS CDNA CLONE. Most importantly, miR-200c strongly suppressed the ability of normal mammary stem cells to form mammary ducts and tumor formation driven by human BCSCs in vivo. View details for DOI 10.1073/pnas.0610117104, View details for Web of Science ID 000243761100053. The wild-type p53/GFP fusion protein was localized in the cytoplasm, the nucleus, or both compartments in a subset of the cells. The HUT-102 cell line, derived from a cutaneous T-cell lymphoma and infected with HTLV, expresses several cellular oncogenes. High-dose chemotherapy (HDCT) and autologous bone marrow transplantation (BMT) is frequently used to treat patients with metastatic cancer including breast cancer and neuroblastoma. 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. Effective treatment of cancer will require therapeutic strategies that are able to target and eliminate this tumorigenic subset of cells. Furthermore, in human tissues overexpression of USP16 reduces the expansion of normal fibroblasts and postnatal neural progenitors, whereas downregulation of USP16 partially rescues the proliferation defects of Down's syndrome fibroblasts. His best known works are the script he wrote with American film director Stanley Kubrick for 2001: A Space Odyssey (1968) and the novel of that film. 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. By complementation of the E1a protein in trans, Ad5ERE2 allows restricted replication of a conventional E1a-deleted adenoviral vector. Programmed cell death (PCD) plays an important role in normal and malignant hematopoieis. This demands a complex crosstalk between extrinsic signals from the microenvironment and the cell-intrinsic regulators of self-renewal. View details for Web of Science ID A1995RP92400014. Finally, questions regarding p53 cellular trafficking will also be discussed. Eipers, P. G., Krauss, J. C., Palsson, B. O., Emerson, S. G., Todd, R. F., Clarke, M. F.

The fragment with a tandem repeat of the 72-bp element also does not associate randomly with histones. A cDNA library was constructed from the HUT102 cell line established from a patient with adult T-cell leukemia/lymphoma and screened for cDNA clones that contain (i) cellular sequences abundantly expressed in HUT102 cells and not in the virus-negative T-cell line HUT78, and (ii) viral long terminal repeat (LTR) sequences either in the 5' end or in the 3' end. The ability to self-renew is essential for all kinds of stem cells regardless of tissue type. patients) at transplant: primary refractory disease (six), first relapse (10), second relapse (eight), third relapse (five). These data suggest that the late fall in c-myb levels may be required in order for differentiation to occur. 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. While cell lines expressing p53 alone rapidly died, those cells co-expressing Bcl-XL survived. To evaluate the feasibility of positron emission tomography (PET) with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) in patients with germ cell tumor (GCT) to monitor treatment and differentiate residual masses after chemotherapy.Twenty-six FDG PET studies were performed in 21 patients with GCT, FDG uptake of tumors was interpreted visually, and the lean standardized uptake value (SUVlean) was determined. However, no indomethacin or ETYA inhibition of oxygen utilization was detected in the presence of 1 mM KCN, suggesting that the inhibitable portion of the respiratory burst observed with indomethacin or ETYA was dependent on mitochondrial respiration. Zabala, M., Lobo, N. A., Antony, J., Heitink, L. S., Gulati, G. S., Lam, J., Parashurama, N., Sanchez, K., Adorno, M., Sikandar, S. S., Kuo, A. H., Qian, D., Kalisky, T., Sim, S., Li, L., Dirbas, F.

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. Biography. Metastasis is the main cause of death in breast cancer patients. We show that human colon cancer tissues contain distinct cell populations whose transcriptional identities mirror those of the different cellular lineages of normal colon. 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. (Funded by the National Comprehensive Cancer Network, the National Institutes of Health, and others.). Thus, we reveal USP16 as a novel target in an AD model that can both ameliorate the NPC defect and rescue memory and learning through its regulation of both Cdkn2a and BMP signaling.'. Here we show that normal mammary epithelial stem cells contain lower concentrations of ROS than their more mature progeny cells. Street. He was Director General of the Royal United Services Institute from 2017-2015 and is now a Distinguished Fellow at RUSI. Here, we report the results of using a bioreactor system to expand hematopoietic cells after a brief retrovirus infection using a high titer, replication defective virus encoding for murine CD18. Importantly, infection with the bcl-xS adenovirus resulted in rapid loss of cell viability, DNA fragmentation, and morphological features of apoptosis even in NB cells transfected to overexpress Bcl-2 and Bcl-xL. After 48 h in culture, DR antigen expression was substantially increased, but no significant changes were observed in methylation of the DR alpha locus or in the amount of DR mRNA which was present. These studies show that the metabolic and secretory behavior of genetically engineered cells is influenced by the medium exchange schedule. We developed northstar, a computational approach to classify thousands of cells based on published data within seconds while simultaneously identifying and highlighting new cell states such as malignancies. 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. 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. However, deletions of more than two amino acids between this region abolished the transport of p53 into the nucleus.

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. These cancer stem cells share many characteristics with normal stem cells, including self-renewal and differentiation. Adjunct Senior Lecturer Dr Urs Wermuth. 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. Furthermore, we found that the c-myc and bcl-2 genes cooperate to inhibit p53 functions. Clarke, M. F., Westin, E., Schmidt, D., Josephs, S. F., Ratner, L., WONGSTAAL, F., Gallo, R. C., Reitz, M. S. IDENTIFICATION OF THE HUMAN T-CELL LYMPHOMA VIRUS IN B-CELL LINES ESTABLISHED FROM PATIENTS WITH ADULT T-CELL LEUKEMIA. The p53-independent pathway does not appear to involve apoptosis and occurs at a later time, starting 48 h after X-ray exposure. He is so driven about his work and is so charismatic to his students. However, the consequences of the underlying gene-dosage imbalance on adult tissues remain poorly understood. Haematopoiesis is maintained by a hierarchical system where haematopoietic stem cells (HSCs) give rise to multipotent progenitors, which in turn differentiate into all types of mature blood cells.
