We compared commercially available single-cell RNA amplification methods with both microliter and nanoliter volumes, using sequence from bulk total RNA and multiplexed quantitative PCR as benchmarks to systematically evaluate the sensitivity and accuracy of various single-cell RNA-seq approaches. 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. Location University of Rochester 402 Hutchison Hall P.O. Recently, his group described a molecular mechanism that confers resistance to radiation in breast cancer stem cells.

The Thy-1+CD24medCD49fhigh phenotype contained the majority of the serially transplantable epithelial cells. The N-bGM-CSFs demonstrated GM-CSF receptor specific binding that was displaceable by excess underivatized protein, with the detected fluorescence signal decreasing with increasing biotin to protein molar ratio.

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type 5, we have constructed a conditionally replicative adenovirus (Ad5ERE2) in which the E1a and E4 promoters have been replaced by a portion of the pS2 promoter containing two estrogen-responsive elements (EREs). We discuss possible functional consequences of such nucleosome positioning.

Similar to TWF1, VIM also regulates F-actin formation, a key component of cellular transition to a more invasive mesenchymal phenotype. One of these, the goblet cells, contained a distinct cKit/CD117(+) crypt base subpopulation that expressed Dll1, Dll4, and epidermal growth factor, similar to Paneth cells, which were also marked by cKit.

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. In this episode, Eliot Wilson talks to Professor Michael Clarke, former head of the Royal United Services Institute, about the UK's Integrated Review and how far it represents a break from traditional thinking on our place in the world. Biotinylated granulocyte/macrophage colony-stimulating factor (GM-CSF) analogues with different linkage chemistries and levels of conjugated biotin were synthesized by reacting recombinant human GM-CSF with sulfosuccinimidyl 6-biotinamidohexanoate or biotin hydrazide/1-[3-(dimethylamino)-propyl]-3-ethylcarbodiimide. This apparent paradox is the focus of our interest. Recent studies have uncovered a number of Bcl-2-related gene products that regulate apoptosis either negatively or positively, and Bcl-2 forms heterodimers with at least one of these proteins, Bax. erenakgun@g.harvard.edu. Resistance to apoptosis plays an important role in tumors that are refractory to chemotherapy. Caldwell, J., LOCEY, B., Clarke, M. F., Emerson, S. G., Palsson, B. O. DIFFERENTIATION OF MOUSE ERYTHROLEUKEMIA-CELLS ENHANCED BY ALTERNATIVELY SPLICED C-MYB MESSENGER-RNA. ANGELOTTI, T. P., Clarke, M. F., Longino, M. A., Emerson, S. G. THE CONSTRUCTION OF HIGH-EFFICIENCY HUMAN BONE-MARROW TISSUE EXVIVO. A Quiescent Bcl11b High Stem Cell Population Is Required for Maintenance of the Mammary Gland. Hoey, T., Yen, W., Axelrod, F., Basi, J., Donigian, L., Dylla, S., Fitch-Bruhns, M., Lazetic, S., Park, I., Sato, A., Satyal, S., Wang, X., Clarke, M. F., Lewicki, J., Gurney, A. In contrast to our previous experience, where all such lines expressed T cell markers, these two cell lines expressed B cell antigens and Ig light chains (kappa on CF-2, lambda on HS). Imatinib inhibited growth of KIT(+) colon cancer organoids in culture and growth of xenograft tumors in mice. When breast cancer cells mixed with hematopoietic cells were infected with the bcl-x(s) adenovirus, cancer cells were selectively killed by the suicide adenoviruses. Molofsky, A.

School of Civil Engineering +61 7 336 56464. william.clarke@uq.edu.au. This phenotypic diversity is driven by a small subset of mammary tumour stem cells. All three analogues retained full agonist activity relative to the native protein (EC50 = 10-15 pM) when assayed for the stimulation of human bone marrow progenitor cell growth. Self-renewal requires the integration of survival signals and proliferation controls with the maintenance of an undifferentiated state. 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. 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.

Taken together, these data demonstrate that cells within the CD44(+) population of human HNSCC possess the unique properties of cancer stem cells in functional assays for cancer stem cell self-renewal and differentiation and form unique histological microdomains that may aid in cancer diagnosis. In the absence of Bmi-1, the cyclin-dependent kinase inhibitor gene p16Ink4a is upregulated in neural stem cells, reducing the rate of proliferation. Pathways that regulate epigenetic control of stem cell identity are critical to the molecular etiology of cancer. In 2007, he became the Director of the Royal United Services Institute. 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. Usp16 can remove ubiquitin from histone H2A on lysine 119, a critical mark for the maintenance of multiple somatic tissues. 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. We previously reported that miR-142 and miR-150 are upregulated in human breast cancer stem cells (BCSCs) as compared to the non-tumorigenic breast cancer cells. 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. The reasons for the limited longevity are unknown. In DNA from the T-cells not expressing DR alpha mRNA, all of the potential HpaII sites within the BglII fragment appeared to be methylated. Herein, we present a discussion around the issues facing treatment of patients with CRCliver metastases, including the relationship of discretegene signatures with prognosis. BIO-IMEB - Biofilms in Industry, Medicine & Environmental Biot, Galway, Ireland, 9-14 August 2003. Liu, H., Shimono, Y., Bockhorn, J., Olopade, F., Greene, G., Clarke, M. F. Cancer stem cells from human breast tumors are involved in spontaneous metastases in orthotopic mouse models. Further study with ETYA showed that the inhibitor at 2 x 10(-5) M had little effect on uptake of 125I-labeled zymosan but did abolish the conversion of 14C-arachidonic acid to a compound that co-migrated with authentic 12-HETE on silica gel plates. Since cancers arise as a result of a series of genetic mutations, a better understanding of the consequences of these mutations on the underlying biology of the neoplastic cells will help the development of more effective therapies. Rather than terminally differentiating, these cells are induced to undergo apoptosis. Although cancer cell lines provide invaluable information, their biological properties often differ in crucial ways from de novo cancer cells. In one clone, the alternative splicing would generate a predicted myb protein with a three amino acid deletion in the region involved in transcription activation. These latter cell lines do express HLA-DR alpha-mRNA, as well as HLA-DR surface antigens.

Hernandez-Alcoceba, R., Pihalja, M., Wicha, M. S., Clarke, M. F. A bipartite nuclear localization signal is required for p53 nuclear import regulated by a carboxyl-terminal domain, Germ cell tumor: Differentiation of viable tumor, mature teratoma, and necrotic tissue with FDG PET and kinetic modeling. The human RGS18 ortholog has a tissue-specific expression pattern similar to that of mouse RGS18. 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+"). The expression of the E1A gene in both viruses is controlled by a minimal dual-specificity promoter that responds to estrogens and hypoxia. 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. We show that single-cell RNA-seq can be used to perform accurate quantitative transcriptome measurement in individual cells with a relatively small number of sequencing reads and that sequencing large numbers of single cells can recapitulate bulk transcriptome complexity. Dalerba, P., Dylla, S. J., Park, I., Liu, R., Wang, X., Cho, R. W., Hoey, T., Gurney, A., Huang, E. H., Simeone, D. M., Shelton, A. 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. Adipose mesenchymal stromal cells, haematopoietic stem cells and hepatocytes are among those cell types that are especially responsive. Park, I., Qian, D., Kiel, M., Becker, M., Prohaska, S., Weissman, I., Morrison, S., Clarke, M. Bmi-1 is required for maintenance of adult self-renewing haematopoietic stem cells. This demands a complex crosstalk between extrinsic signals from the microenvironment and the cell-intrinsic regulators of self-renewal. 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. Isobe, T., Zarneger, M. A., Matsubara, J., Abdel-Wahab, O., Clarke, M. F. Usp16 modulates Wnt signaling in primary tissues through Cdkn2a regulation. Results The transcription factor CDX2 ranked first in our screening test. 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. He was Director General of the Royal United Services Institute from 2017-2015 and is now a Distinguished Fellow at RUSI. A panel of NB cell lines (CHP-382, GOTO, SHEP-1, SHSY-5Y, and GI-CA-N) were infected with either a bcl-xS adenovirus (pAdRSV-bcl-xS) or a control virus (pAdRSV-lac-z).

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. The regulation of hematopoietic stem cell (HSC) homeostasis is not well understood. patients) at transplant: primary refractory disease (six), first relapse (10), second relapse (eight), third relapse (five). In contrast to cells in G1, cells cultured at 32.5 degrees C for prolonged periods during S phase and G2/M, and then returned to 37.5 degrees C, did not become committed to cell death. To understand the regulation of p53 cellular trafficking, we have previously identified two p53 domains involved in its localization. In contrast to wild-type MEL cells, both clones failed to display phenotypic markers of differentiation and continued to proliferate for up to 10 days of culture. At the molecular level, Usp16 affects Rspo-mediated phosphorylation of LRP6. In murine leukemia models induced by P210BCR/ABL or TEL/PDGFbetaR + AML1/ETO, Bmi-1 was not overexpressed in leukemic HSCs, despite the increase in the HSC numbers. A better understanding of the molecular mechanisms underlying metastasis is needed to develop more effective treatments. At the time of ABMT, 10 were chemosensitive, four were chemoresistant, and 10 were absolutely refractory to platinum. Treatment of these T-cells with 5-azacytidine resulted in the induction of DR surface antigen expression, the appearance of DR alpha mRNA, and the partial demethylation of the DR alpha DNA sequences. Therefore, to better treat cancer it may be necessary to develop novel methods to overcome the effects of the Bcl-2 family. He has a long-standing interest in the impact of fire upon fauna. 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. 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. Michael Clarke (academic) is a British academic who specialises in defence studies. 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. Eighteen relapses occurred a median of 4 months after ABMT I (two late relapses at 28 and 44 months). Regulation of the Wnt pathway in stem cells and primary tissues is still poorly understood. Wu, A. R., Hiatt, J. Diehn, M., Cho, R. W., Lobo, N. A., Kalisky, T., Dorie, M. J., Kulp, A. N., Qian, D., Lam, J. S., Ailles, L. E., Wong, M., Joshua, B., Kaplan, M. J., Wapnir, I., Dirbas, F.

These models recapitulate human cancer features not captured with previous models, including spontaneous metastasis in particular, and provide a useful platform for studies of breast tumor initiation and progression. Furthermore, we identify unique, CSC-specific, remodeling events. Professor Clarke's current research interests are the molecular mechanisms of cell division, chromosome instability and mitotic cell death. Michael W. Clark is the Director of the Center for Business and Economic Research and an Associate Professor of Economics at the University of Kentucky's Gatton College of Business and Economics. Professor Michael Clarke said that sending soldiers to take Kyiv was 'massively foolish' and could become a 'peak Putin' moment that leads eventually to his downfall. The possible significance of this finding is discussed. View details for DOI 10.1016/j.gde.2003.11.007, View details for Web of Science ID 000188978200008. Fifteen (52%) received both transplants. This report summarizes the major topics discussed and the future directions that research should take. Published Oct. 2, 2020 Updated Oct. 5, 2020. In many tissues, a cellular hierarchy exists in which a small population of stem cells is responsible for the production of the mature cells of the organ. To date, therapies targeting end-stage disease plaques, tangles, or inflammation have limited efficacy. The molecular mechanisms that limit the proliferation capacity of multipotent progenitors and other more mature progenitors are not fully understood. Gene expression analysis of cells isolated from nonadherent mammospheres revealed overlapping genetic programs with other stem and progenitor cells and identified new markers that may be useful in the identification of mammary stem cells. PHD Student in Computer Science. Conversely, a chromosome 1 locus exhibited suggestive linkage to restricted progenitor frequencies but was not linked to HSC frequency. No activating mutations in KIT were detected in DLD1, POP77, or UM-COLON#8 cells. Thus, the predicted transforming product, a protein of 27,281 daltons, may be the actual precursor for normal human platelet-derived growth factor chain A.

In the validation data set, which included 314 patients, the rate of 5-year disease-free survival was lower among the 38 patients (12.1%) with CDX2 protein-negative colon cancers than among the 276 (87.9%) with CDX2 protein-positive colon cancers (hazard ratio, 2.42; 95% CI, 1.36 to 4.29; P=0.003). Additionally, we suggest that constitutive expression of c-myb does not block early commitment events such as activation of histone Hl', subsequent chromatin condensation, and alteration of proliferation-related gene expression. These results indicate that, similar to normal tissue stem cells, subsets of CSCs in some tumours contain lower ROS levels and enhanced ROS defences compared to their non-tumorigenic progeny, which may contribute to tumour radioresistance. 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. 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. 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.

Mark Malloch Brown, Baron Malloch-Brown (* 1953), Politiker und stellvertretender Generalsekretr der Vereinten Nationen. The cumulative data provide the foundation for an atlas of transcriptomic cell biology. The in vitro culture of mouse bone marrow (Dexter cultures) has allowed a detailed analysis of the biology of murine hematopoiesis. This makes it virtually impossible to infect the majority of tumor cells in vivo and results in inadequate gene transfer.

Sequences within this region were identical to those previously determined for the exons of the normal human c-sis gene. This transcriptomic atlas-which we denote Tabula Muris Senis, or 'Mouse Ageing Cell Atlas'-provides molecular information about how the most important hallmarks of ageing are reflected in a broad range of tissues and cell types. Hematopoietic stem cell gene therapy holds the promise of being able to treat a variety of inherited and acquired diseases of the hematopoietic stem cell. Strategies that enhance the activity of ADCC effectors, including NK cells, may improve the efficacy of trastuzumab. In a pooled database of all patient cohorts, the rate of 5-year disease-free survival was higher among 23 patients with stage II CDX2-negative tumors who were treated with adjuvant chemotherapy than among 25 who were not treated with adjuvant chemotherapy (91% vs. 56%, P=0.006). In the present study, further mutagenesis analyses were carried out between Lys-305 and the major nuclear localization signal (NLS I) of p53. 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. Schaum, N. n., Lehallier, B. n., Hahn, O. n., Plovics, R. n., Hosseinzadeh, S. n., Lee, S. E., Sit, R. n., Lee, D. P., Losada, P. M., Zardeneta, M. E., Fehlmann, T. n., Webber, J.

F., Keller, A. n., Darmanis, S. n., Quake, S. R., Wyss-Coray, T. n. Northstar enables automatic classification of known and novel cell types from tumor samples. The metabolism of oxygen, although central to life, produces reactive oxygen species (ROS) that have been implicated in processes as diverse as cancer, cardiovascular disease and ageing. This is the first example of transformation of NIH-3T3 cells by a human onc gene other than c-ras or Blym, as well as the first demonstration of transformation by a human cDNA clone. The HUT-102 cell line, derived from a cutaneous T-cell lymphoma and infected with HTLV, expresses several cellular oncogenes. Emerging evidence has suggested that the capability of a tumor to grow and propagate is dependent on a small subset of cells within a tumor, termed cancer stem cells. Herrema I, Clarke M. Anaesthesia for retinoblastoma screening - a dilemma. The mammary epithelium undergoes several rounds of extensive proliferation during the female reproductive cycle. He has published internationally on the ecology and conservation biology of birds, reptiles, mammals, fish and plants. Individually and in combinations, IL-3, GM-CSF, and Epo were added to the culture medium of LTBMCs that were maintained with 50% medium volume exchange per day. Following high-dose IR, cell fractionation demonstrated that p53 is induced and targeted to the nucleus. Arthur Thomas Malkin (1803-1888), Pionier der Bergsteigerei und Schriftsteller. Mcl1, Tel/Etv6, Gfi1, Pten and Stat5) have been identified. These results suggest all human solid tumor cells require CD47 expression to suppress phagocytic innate immune surveillance and elimination. It kills tumor cells by several mechanisms, including antibody-dependent cellular cytotoxicity (ADCC). Russian forces are. 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. We screened for genetic polymorphisms that were linked to differences between mouse strains in the numbers of long-term reconstituting HSCs or restricted progenitors in the bone marrow. We performed multiplexed single-cell gene expression analysis with quantitative reverse transcriptase polymerase chain reaction followed by hierarchical clustering analysis to characterize distinct cell types. We have introduced this construct into Friend erythroleukemia (F-MEL) cells and have isolated a number of clones which contain intact and transcriptionally active human c-myb sequences. When a virus expressing the proapoptotic gene Bc1-xs (Clarke et al., Proc. We developed selective anti-human and anti-mouse DLL4 antibodies to dissect the mechanisms involved by analyzing the contributions of selectively targeting DLL4 in the tumor or in the host vasculature and stroma in xenograft models derived from primary human tumors. G1 arrest at 37.5 degrees C, utilizing either mimosine or isoleucine deprivation, does not lead to rapid cell death. Moreover, the inherent ability of residual CoCSC to generate tumors appears preserved.

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. A., Parmiani, G., Castelli, C., Clarke, M. F. Identification of pancreatic cancer stem cells. With the use of subgroup analysis involving independent and retrospective cohorts of patients with stage II or stage III colon cancer, the top candidate gene was tested for its association with disease-free survival and a benefit from adjuvant chemotherapy. 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. We focused our analysis of gene expression on RNA from primitive leukemia-initiating cells, which harbor 5q deletions, and analyzed 12 genes within the CDR that are expressed by normal hematopoietic stem cells. IL-10 function is required for the full protective effect of small-molecule Hedgehog pathway activation in colitis; this pharmacologic augmentation of Hedgehog pathway activity and stromal IL-10 expression are associated with increased presence of CD4(+)Foxp3(+) regulatory T cells. The Weight can be changed regularly, here we have added the latest value. These tools should lead to new insights into the cellular and molecular mechanisms that drive human breast cancer growth and invasion. Our laboratory has developed a novel mouse model that reliably permits individual cancer cells isolated directly from patients' tumors to be assayed. Downregulation of Usp16, either by mutation of a single normal Usp16 allele or by short interfering RNAs, largely rescues all of these defects. Weber, B. L., Westin, E. H., Clarke, M. F. ALTERNATIVE SPLICING OF THE HUMAN C-MYB GENE. LONDON Dancer, choreographer, ex-heroin addict, prodigal son, perfectionist, art-world darling, club-world star: Michael Clark was for a long time . The rapid medium exchange combined with the addition of human hematopoietic CSFs significantly enhances the proliferation and differentiation of LTBMCs. High-level expression of the c-sis oncogene, which encodes the beta chain of platelet-derived growth factor, transforms immortalized rodent fibroblasts in vitro to a malignant phenotype. Aldehyde dehydrogenase 1 gene expression and enzymatic activity are elevated in CoCSC and using an in vitro culture system that maintains CoCSC as demonstrated by serial transplants and lentiviral marking of single cell-derived clones, we further show that ALDH1 enzymatic activity is a major mediator of resistance to cyclophosphamide: a classical chemotherapeutic agent.CoCSC are enriched in colon tumors following chemotherapy and remain capable of rapidly regenerating tumors from which they originated.
