Single-cell RNA sequencing (scRNA-seq) is a powerful approach for reconstructing cellular differentiation trajectories. Loss of Bcl11b leads to a Cdkn2a-dependent exhaustion of ductal epithelium and loss of epithelial cell regenerative capacity. 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. Facebook gives people the power. Furthermore, we propose a model in which transformation of stem cells, or early progenitor cells, results in carcinogenesis. Notably, subsets of CSCs in some human and murine breast tumours contain lower ROS levels than corresponding non-tumorigenic cells (NTCs).

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. Under the standard bone marrow culture conditions, even with a high stem cell renewal rate, the cultures appear to be destined to fail. The subpopulation of human colorectal tumor cells with an ESA(+)CD44(+) phenotype are uniquely responsible for tumorigenesis and have the capacity to generate heterogeneous tumors in a xenograft setting (i.e. As we continue to advance clinically and technologically in the field of colorectal tumor biology, ourgoal should be continuedrefinement of predictive and prognostic studiesto decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailoredmultidisciplinary approach to cancer care. Schott, A. F., Apel, I. J., Nunez, G., Clarke, M. F. BCL-2 PROTECTS MURINE ERYTHROLEUKEMIA-CELLS FROM P53-DEPENDENT AND -INDEPENDENT RADIATION-INDUCED CELL-DEATH.

Isolation and molecular characterization of cancer stem cells in MMTV-Wnt-1 murine breast tumors. Recent studies elucidated the presence of cancer stem cells that have the exclusive ability to regenerate tumors. Clinical and Therapeutic Implications of Cancer Stem Cells. Single-cell RNA sequencing confirms the accumulation of T cells and B cells in adipose tissue-including plasma cells that express immunoglobulin J-which also accrue concurrently across diverse organs. Furthermore, the oxygenation of arachidonic acid requires little of the oxygen consumed by phagocytosing alveolar macrophages. This conserved requirement for Bmi-1 to promote self-renewal and to repress p16Ink4a expression suggests that a common mechanism regulates the self-renewal and postnatal persistence of diverse types of stem cell. Resultant tumors had a phenotypic diversity similar to that of the original tumor and behaved in a similar manner when passaged. Recently, his group described a molecular mechanism that confers resistance to radiation in breast cancer stem cells. 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. These studies show that the metabolic and secretory behavior of genetically engineered cells is influenced by the medium exchange schedule. (2007) analyze the relationship between CSC and tumor metastasis. It kills tumor cells by several mechanisms, including antibody-dependent cellular cytotoxicity (ADCC). 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. According to a story Tom Hanks told at. 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. Cho, R.

W., Tian, Q., Lee, T. M., Yan, X., Liu, R., Chiang, J., Hood, L., Clarke, M. F., Weissman, I. L. Identification of Conserved Gene Expression Programs in Epithelial Cancer Stem Cells. Receptor tyrosine kinase (RTK) inhibitors have advanced colon cancer treatment. This concept was first demonstrated in the study of leukemia where only cells with specific surface antigen profiles were able to cause leukemia when engrafted into immunodeficient mice. 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. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem ofdetecting and treating the metastatic spread of CRC to the liver. 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 tumors in these tissues consist of heterogeneous populations of cancer cells that differ markedly in their ability to proliferate and form new tumors. Yoo, S., Chandhasin, C., Del Rosario, J.

The combination of IL-3 + GM-CSF + Epo generated the most prolific cultures with an order of magnitude increase in nonadherent cell production from weeks 2 through 8 in culture as compared with unsupplemented controls. They were introduced into the E4 region of AdEHT2 and AdEHE2F, respectively. Utilizing computer-assisted integration techniques, we have theoretically simulated culture cell production kinetics to help identify factors that may be responsible for culture decay, as well as to suggest possible means of improving culture longevity.

KIT Signaling Promotes Growth of Colon Xenograft Tumors in Mice and Is Up-Regulated in a Subset of Human Colon Cancers. Identifying the metastatic seeds of breast cancer. These results indicate that a basic domain other than the well defined NLS is required for the nuclear import of p53. We demonstrate that reversing impaired NPC self-renewal via genetic reduction of USP16, a histone modifier and critical physiological antagonist of the Polycomb Repressor Complex 1, can prevent downstream cognitive defects and decrease astrogliosis in vivo. Upon inactivation of KrasG12D , tumors initially regress and enter remission. View details for DOI 10.1038/s41598-020-71805-1. View details for Web of Science ID 000079323200036. Three well-known tumor suppressors, p53, p16INK4a, and p19ARF, have been connected to the limiting of stem cell self-renewal and proliferation. The Thy-1-CD24medCD49fhigh phenotype contains a rare progenitor population that is able to form primary mammary outgrowths with significantly decreased serial in vivo transplantation potential.CONCLUSIONS: Therefore, Thy-1 expression in the immature cell compartment is a useful tool to study the functional heterogeneity that drives mammary gland development and has implications for disease etiology.

F. Serially transplantable mammary epithelial cells express the Thy-1 antigen. Evidence from studies in murine and human embryonic stem cells indicates that Polycomb group proteins play a dynamic role in concert with master transcriptional regulators in actively maintaining an undifferentiated state, suggesting that this mechanism applies to multiple types of stem cell. View details for Web of Science ID 000243301800039. Intravital multiphoton imaging reveals multicellular streaming as a crucial component of in vivo cell migration in human breast tumors. We demonstrate that nonadherent mammospheres are enriched in early progenitor/stem cells and able to differentiate along all three mammary epithelial lineages and to clonally generate complex functional structures in reconstituted 3D culture systems. Microarray-based multigene-expression signatures derived from stem cells and progenitor cells hold promise, but they are difficult to use in clinical practice. 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. 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. Who we Are. However, the consequences of the underlying gene-dosage imbalance on adult tissues remain poorly understood. Al-Hajj, M., Becker, M. W., Wichal, M., Weissman, I., Clarke, M. F. Bmi1, stem cells, and senescence regulation. Effective treatment of cancer will require therapeutic strategies that are able to target and eliminate this tumorigenic subset of cells. We investigated the role of the RTK KIT in development of human colon cancer.An array of 137 patient-derived colon tumors and their associated xenografts were analyzed by immunohistochemistry to measure levels of KIT and its ligand KITLG. Recently, it has become apparent that some oncogenes and tumor suppressor genes also regulate self-renewal, the process by which stem cells maintain themselves. The possible significance of this finding is discussed.

Analysis of HUT102 DNA shows that one allele of the KT1 UCR is rearranged. As well as addressing the patient's medical needs, these highly trained professionals . 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. Although initial adhesion of hematopoietic cells was improved by the presence of both ECMs, the overall progenitor and nonadherent cell productivity was not improved nor did the stroma grow to confluency faster. [2] [3] Biography [ edit] Our studies show that coincident expression of human Bcl-2 protein with p53 prolongs survival of murine erythroleukemia cells. We therefore propose to initiate a phase I clinical trial to test the safety of this virus in women with breast cancer undergoing high does chemotherapy and autologous BMT. He was the founding Director of the International Policy Institute at King's College London from 2001-2005 and Head of the School of Social Science and Public Policy at KCL in 2004-05. Knockdown of KIT decreased proliferation of colon cancer cell lines and growth of xenograft tumors in mice compared with control cells. 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. Two populations of cells, HSCs and MPP cells, were compared for differential gene expression using microarray analysis. Our multidisciplinary group held a state-of-the-science symposium this past year to review advancesin this rapidly evolving field. Following release into G1, cells became irreversibly committed to cell death after 4 h at 32.5 degrees C. Commitment to cell death correlated with the first appearance of fragmented DNA. The effect of these changes on protein function is currently unknown. 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). 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. 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. 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.

When viability was measured 24 h post-radiation, cells that had been briefly exposed to wtp53 immediately after X-ray irradiation had decreased survival as compared to unirradiated cells expressing wtp53 or X-ray irradiated DP16-1 cells. A large number of genes that were differentially expressed by enriched populations of HSCs and MPP cells were identified. The molecular mechanisms that limit the proliferation capacity of multipotent progenitors and other more mature progenitors are not fully understood. Here we performed bulk RNA sequencing of 17 organs and plasma proteomics at 10 ages across the lifespan of Mus musculus, and integrated these findings with data from the accompanying Tabula Muris Senis2-or 'Mouse Ageing Cell Atlas'-which follows on from the original Tabula Muris3. Although data have been provided to support this theory in human blood, brain, and breast cancers, the identity of pancreatic cancer stem cells has not been determined. View details for Web of Science ID 000083623000026. The theory of cancer stem cells states that a subset of cancer cells within a tumor has the ability to self-renew and differentiate. Thus, bcl-2 protects cells from p53-dependent radiation-induced apoptotic cell death and attenuates p53-independent radiation-induced cell death.

Replication-deficient viral vectors are currently being used in gene transfer strategies to treat cancer cells. Here we describe a method for the rapid incorporation of exogenous promoters into the E1A and E4 regions of the human adenovirus type 5 genome. Morrison, S. J., Qian, D., Jerabek, L., Thiel, B. Furthermore, we identify unique, CSC-specific, remodeling events. 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. Faculty. He also carries out research into the cellular responses to anti-cancer drugs. Mcl1, Tel/Etv6, Gfi1, Pten and Stat5) have been identified. Further investigation will reveal whether this translates to improved therapy in the future. Uncultured peripheral blood T-cells from human T-cell leukemia-lymphoma virus-infected individuals expressed DR antigens at a low level, and the DR alpha locus was partially unmethylated. These results suggest that LEFTY1 is an endogenous dual-SMAD inhibitor and that suppressing its function may represent a therapeutic vulnerability in breast cancer.

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). 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. 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. The number of HSCs in the fetal liver of Bmi-1-/- mice was normal. View details for Web of Science ID A1984SP90200011. To solve this problem, a new generation of tumor-specific, conditionally replicative adenoviruses is being developed. 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. These cancer stem cells share many characteristics with normal stem cells, including self-renewal and differentiation. A better understanding of the molecular mechanisms underlying metastasis is needed to develop more effective treatments. Michael Clarke is a British academic who specialises in defence studies. Deficiency in the polycomb family transcriptional repressor Bmi-1 leads to progressive postnatal growth retardation and neurological defects. View details for DOI 10.1038/s41586-020-2499-y. However, multipotent progenitors lack the ability to self-renew, therefore their mitotic capacity and expansion potential are limited and they are destined to eventually stop proliferating after a finite number of cell divisions. Two distinct technical approaches were used for most organs: one approach, microfluidic droplet-based 3'-end counting, enabled the survey of thousands of cells at relatively low coverage, whereas the other, full-length transcript analysis based on fluorescence-activated cell sorting, enabled the characterization of cell types with high sensitivity and coverage. Bcl11b(high) cells are enriched for cells that can regenerate mammary glands in secondary transplants. Using mammary epithelial-specific mouse models targeting Trp53 and Cdkn2a, the gene coding for p16INK4a and p19ARF, we demonstrate that p53, p16INK4a, and p19ARF do not play a significant role in the limitation of normal mammary epithelium self-renewal and proliferation, whereas in the presence of the inflammatory cytokine TNF-, Trp53-/-Cdkn2a-/- mammary basal cells exhibit amplified proliferation. 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. Clarke, M.
