A subpopulation of tumor cells, termed cancer stem cells (CSC), appears uniquely able to fuel the growth of phenotypically and histologically diverse tumors. 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. Sufficient new cells have to be produced to maintain the integrity of a tissue, but excessive proliferation resulting in tumorigenesis needs to be prevented. 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). During dimethylsulfoxide (DMSO)-induced differentiation of Friend mouse erythroleukemia (MEL) cells there is a biphasic fall in c-myb mRNA levels. A better understanding of the molecular mechanisms underlying metastasis is needed to develop more effective treatments.

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. We demonstrate that radiation-induced cell death occurs by both p53-dependent and -independent pathways and overexpression of bcl-2 modulates both pathways. To examine the role of breast cancer stem cells (BCSCs) in metastasis, we generated human-in-mouse breast cancer orthotopic models using patient tumor specimens, labeled with optical reporter fusion genes. 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. Usp16 can remove ubiquitin from histone H2A on lysine 119, a critical mark for the maintenance of multiple somatic tissues. Ailles, L., Prince, M., Joshua, B., Doweck, I., Kaplan, M., Clarke, M., Weissman, I. These tools should lead to new insights into the cellular and molecular mechanisms that drive human breast cancer growth and invasion. CDX2 as a Prognostic Biomarker in Stage II and Stage III Colon Cancer. The theory of cancer stem cells states that a subset of cancer cells within a tumor has the ability to self-renew and differentiate. 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. Anti-CD47 antibody therapy initiated on larger tumors inhibited tumor growth and prevented or treated metastasis, but initiation of the therapy on smaller tumors was potentially curative. This development may play an important role in realizing human gene therapy. It has been viewed by tens of millions of people around the world, including in China, where Sandel was named the "most . It has recently been shown that central nervous system stem cells and haematopoietic stem cells and early progenitors contain lower levels of ROS than their more mature progeny, and that these differences are critical for maintaining stem cell function. Downregulation of Usp16, either by mutation of a single normal Usp16 allele or by short interfering RNAs, largely rescues all of these defects. Best response after ABMT included: two CR, one CR surgically NED, five PR, three PR surgically NED, seven SD, and eight PD. Here we report that Usp16, a negative regulator of Bmi1/PRC1 function, modulates the Wnt pathway in mammary epithelia, primary human fibroblasts and MEFs, affecting their expansion and self-renewal potential. Zabala, M., Lobo, N. A., Seoane, J. Overall, we demonstrate a novel approach for imaging physiologic and pathological remodeling. While cell lines expressing p53 alone rapidly died, those cells co-expressing Bcl-XL survived. View details for Web of Science ID 000182853100046. We developed an immunodeficient mouse model to test the tumorigenic potential of different populations of cancer cells derived from primary, unmanipulated human HNSCC samples. However, the underlying molecular mechanisms are poorly characterized. Stem cells in normal breast development and breast cancer. My research is located in three overlapping fields: (a) linguistic and cultural transfer from Mediterranean Antiquity to the medieval European vernaculars; (b) comparative study of epic and heroic narrative traditions, especially in Greek, Latin, and Babylonian, and of their Celtic and Germanic successors and analogues; (c) semantic The Shep-1 neuroblastoma cell line is highly resistant to IR. Dylla, S. J., Beviglia, L., Park, I., Chartier, C., Raval, J., Ngan, L., Pickell, K., Aguilar, J., Lazetic, S., Smith-Berdan, S., Clarke, M. F., Hoey, T., Lewicki, J., Gurney, A. L. Characterizing metastatic cancer stem cells from human breast cancer. These analogues were compared to determine the effect of biotinylation on biological activity and GM-CSF receptor binding characteristics. Control cultures that were exposed to conCM after 4 weeks in culture significantly improved their cell productivity during the latter 4 weeks of culture compared with control. Recent evidence suggests that a subset of cancer cells within some tumors, the so-called cancer stem cells, may drive the growth and metastasis of these tumors. This model, first developed in human myeloid leukemias, is today being extended to solid tumors, such as breast and brain cancer. Patsialou, A., Bravo-Cordero, J., Wang, Y., Liu, H., Clarke, M. F., Condeells, J. S. Deregulation of stem cell self-renewal pathways in cancer, MicroRNA-30c inhibits human breast tumour chemotherapy resistance by regulating TWF1 and IL-11. Notably, these gene sets show similar expression across tissues, differing only in the amplitude and the age of onset of expression. Reitz, M. S., Mann, D., Clarke, M. F., Kalyanaraman, V. S., Robert-Guroff, M., Popovic, M., Gallo, R. C. HOMOLOGY OF HUMAN T-CELL LEUKEMIA-VIRUS ENVELOPE GENE WITH CLASS-I HLA-GENE. The existence of CSCs mandates careful analysis and comparison of normal tissue stem cells and CSCs to identify differences between the two cell types. Clarke, M. F., Clevers, H., Eaves, C. J., Weinberg, R. A., Rajasekhar, V. K. Quantitative assessment of single-cell RNA-sequencing methods. 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. The stromal cell layer is believed to play an important role in long-term human bone marrow cultures (LTHBMCs). Receptor tyrosine kinase (RTK) inhibitors have advanced colon cancer treatment.

Identification of a subpopulation of cells with cancer stem cell properties in head and neck squamous cell carcinoma. Modulation of p53 function is of interest, therefore, both in understanding the control of apoptosis and as a potential therapeutic intervention. When a promoter containing these elements is used to control the expression of the pro-apoptotic gene harakiri, the induction of cell death can be activated by estrogens and hypoxia, and inhibited by antiestrogens such as tamoxifen. 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. The p53-independent pathway does not appear to involve apoptosis and occurs at a later time, starting 48 h after X-ray exposure. List A-Z. Widespread activation of immune cells is especially pronounced, and is first detectable in white adipose depots during middle age. View details for DOI 10.1016/j.jcmgh.2017.01.006. Previous studies have shown that blocking DLL4 signaling reduced tumor growth by disrupting productive angiogenesis. View details for Web of Science ID 000178717500001. We then determined the effects of intratumoral injection of bcl-xs adenovirus on solid MCF-7 tumors in nude mice. 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. 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.

Pharmacological depletion of ROS scavengers in CSCs markedly decreases their clonogenicity and results in radiosensitization. CHUCK, A. S., Clarke, M. F., Palsson, B. O. bcl-x(s) gene therapy induces apoptosis of human mammary tumors in nude mice. Upon inactivation of KrasG12D , tumors initially regress and enter remission. Single-cell RNA sequencing (scRNA-seq) is a powerful approach for reconstructing cellular differentiation trajectories. 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. Bmi1 is required for the maintenance of adult stem cells in some tissues partly because it represses genes that induce cellular senescence and cell death. Three of these forms co-migrate on Northern blots and are co-expressed in several human hematopoietic cell types. 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.

In culture, codelivery of virus and pE1 resulted in a large increase in infected cells when compared with control cells exposed to virus and pUC19. Ageing is the single greatest cause of disease and death worldwide, and understanding the associated processes could vastly improve quality of life. Professor Clarke is a former Deputy Vice . Professor Clarke has over 45 years of professional experience with approximately 250 publications and presentations. CD47 is therefore a validated target for cancer therapies. Michael Clarke is a UK academic and "terror expert". Regulation of the Wnt pathway in stem cells and primary tissues is still poorly 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. These findings demonstrate that p53 overexpression renders Shep-1 cells IR-sensitive and suggest that large quantities of exogenous p53 can overcome the factors inhibiting p53-mediated, IR-induced apoptosis.

View details for Web of Science ID A1995RY96700021. 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. 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. Therefore, infection with this virus preferentially kills estrogen receptor-positive breast cancer cells, or cells growing under hypoxic conditions. He served as the Head of the School of Life Sciences from 2011-2019. Professor Michael Clarke write a piece in The Sun saying time was running out for Putin. In addition, wild-type p53 expression also prevented FdUrd-induced DNA double-strand breaks and, unexpectedly, single-strand breaks in parental (mature) DNA. Sen, A., Rothenberg, M.
