    Description: Anthrax lethal toxin, produced by the bacterium Bacillus anthracis, is the major cause of death in animals infected with anthrax. One component of this toxin, lethal factor (LF), is suspected to be a metalloprotease, but no physiological substrates have been identified. Here it is shown that LF is a protease that cleaves the amino terminus of mitogen-activated protein kinase kinases 1 and 2 (MAPKK1 and MAPKK2) and that this cleavage inactivates MAPKK1 and inhibits the MAPK signal transduction pathway. The identification of a cleavage site for LF may facilitate the development of LF inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duesbery, N S -- Webb, C P -- Leppla, S H -- Gordon, V M -- Klimpel, K R -- Copeland, T D -- Ahn, N G -- Oskarsson, M K -- Fukasawa, K -- Paull, K D -- Vande Woude, G F -- New York, N.Y. -- Science. 1998 May 1;280(5364):734-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Advanced BioScience Laboratories-Basic Research Program, National Cancer Institute-Frederick Cancer Research and Development Center, Post Office Box B, Frederick, MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9563949" target="_blank"〉PubMed〈/a〉

    Description: Since 1990, the National Cancer Institute (NCI) has screened more than 60,000 compounds against a panel of 60 human cancer cell lines. The 50-percent growth-inhibitory concentration (GI50) for any single cell line is simply an index of cytotoxicity or cytostasis, but the patterns of 60 such GI50 values encode unexpectedly rich, detailed information on mechanisms of drug action and drug resistance. Each compound's pattern is like a fingerprint, essentially unique among the many billions of distinguishable possibilities. These activity patterns are being used in conjunction with molecular structural features of the tested agents to explore the NCI's database of more than 460,000 compounds, and they are providing insight into potential target molecules and modulators of activity in the 60 cell lines. For example, the information is being used to search for candidate anticancer drugs that are not dependent on intact p53 suppressor gene function for their activity. It remains to be seen how effective this information-intensive strategy will be at generating new clinically active agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, J N -- Myers, T G -- O'Connor, P M -- Friend, S H -- Fornace, A J Jr -- Kohn, K W -- Fojo, T -- Bates, S E -- Rubinstein, L V -- Anderson, N L -- Buolamwini, J K -- van Osdol, W W -- Monks, A P -- Scudiero, D A -- Sausville, E A -- Zaharevitz, D W -- Bunow, B -- Viswanadhan, V N -- Johnson, G S -- Wittes, R E -- Paull, K D -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):343-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Pharmacology (LMP), Division of Basic Science, National Cancer Institute (NCI), National Institutes of Health, Bethesda, MD 20892, USA. weinstein@dtpax2.ncifcrf.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994024" target="_blank"〉PubMed〈/a〉

    Description: The exchange of the oocyte's genome with the genome of a somatic cell, followed by the derivation of pluripotent stem cells, could enable the generation of specific cells affected in degenerative human diseases. Such cells, carrying the patient's genome, might be useful for cell replacement. Here we report that the development of human oocytes after genome exchange arrests at late cleavage stages in association with transcriptional abnormalities. In contrast, if the oocyte genome is not removed and the somatic cell genome is merely added, the resultant triploid cells develop to the blastocyst stage. Stem cell lines derived from these blastocysts differentiate into cell types of all three germ layers, and a pluripotent gene expression program is established on the genome derived from the somatic cell. This result demonstrates the feasibility of reprogramming human cells using oocytes and identifies removal of the oocyte genome as the primary cause of developmental failure after genome exchange.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noggle, Scott -- Fung, Ho-Lim -- Gore, Athurva -- Martinez, Hector -- Satriani, Kathleen Crumm -- Prosser, Robert -- Oum, Kiboong -- Paull, Daniel -- Druckenmiller, Sarah -- Freeby, Matthew -- Greenberg, Ellen -- Zhang, Kun -- Goland, Robin -- Sauer, Mark V -- Leibel, Rudolph L -- Egli, Dieter -- England -- Nature. 2011 Oct 5;478(7367):70-5. doi: 10.1038/nature10397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The New York Stem Cell Foundation Laboratory, New York, New York, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21979046" target="_blank"〉PubMed〈/a〉

    Description: The transfer of somatic cell nuclei into oocytes can give rise to pluripotent stem cells that are consistently equivalent to embryonic stem cells, holding promise for autologous cell replacement therapy. Although methods to induce pluripotent stem cells from somatic cells by transcription factors are widely used in basic research, numerous differences between induced pluripotent stem cells and embryonic stem cells have been reported, potentially affecting their clinical use. Because of the therapeutic potential of diploid embryonic stem-cell lines derived from adult cells of diseased human subjects, we have systematically investigated the parameters affecting efficiency of blastocyst development and stem-cell derivation. Here we show that improvements to the oocyte activation protocol, including the use of both kinase and translation inhibitors, and cell culture in the presence of histone deacetylase inhibitors, promote development to the blastocyst stage. Developmental efficiency varied between oocyte donors, and was inversely related to the number of days of hormonal stimulation required for oocyte maturation, whereas the daily dose of gonadotropin or the total number of metaphase II oocytes retrieved did not affect developmental outcome. Because the use of concentrated Sendai virus for cell fusion induced an increase in intracellular calcium concentration, causing premature oocyte activation, we used diluted Sendai virus in calcium-free medium. Using this modified nuclear transfer protocol, we derived diploid pluripotent stem-cell lines from somatic cells of a newborn and, for the first time, an adult, a female with type 1 diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamada, Mitsutoshi -- Johannesson, Bjarki -- Sagi, Ido -- Burnett, Lisa Cole -- Kort, Daniel H -- Prosser, Robert W -- Paull, Daniel -- Nestor, Michael W -- Freeby, Matthew -- Greenberg, Ellen -- Goland, Robin S -- Leibel, Rudolph L -- Solomon, Susan L -- Benvenisty, Nissim -- Sauer, Mark V -- Egli, Dieter -- T32 DK007647/DK/NIDDK NIH HHS/ -- England -- Nature. 2014 Jun 26;510(7506):533-6. doi: 10.1038/nature13287.

    Description: Mitochondrial DNA mutations transmitted maternally within the oocyte cytoplasm often cause life-threatening disorders. Here we explore the use of nuclear genome transfer between unfertilized oocytes of two donors to prevent the transmission of mitochondrial mutations. Nuclear genome transfer did not reduce developmental efficiency to the blastocyst stage, and genome integrity was maintained provided that spontaneous oocyte activation was avoided through the transfer of incompletely assembled spindle-chromosome complexes. Mitochondrial DNA transferred with the nuclear genome was initially detected at levels below 1%, decreasing in blastocysts and stem-cell lines to undetectable levels, and remained undetectable after passaging for more than one year, clonal expansion, differentiation into neurons, cardiomyocytes or beta-cells, and after cellular reprogramming. Stem cells and differentiated cells had mitochondrial respiratory chain enzyme activities and oxygen consumption rates indistinguishable from controls. These results demonstrate the potential of nuclear genome transfer to prevent the transmission of mitochondrial disorders in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paull, Daniel -- Emmanuele, Valentina -- Weiss, Keren A -- Treff, Nathan -- Stewart, Latoya -- Hua, Haiqing -- Zimmer, Matthew -- Kahler, David J -- Goland, Robin S -- Noggle, Scott A -- Prosser, Robert -- Hirano, Michio -- Sauer, Mark V -- Egli, Dieter -- England -- Nature. 2013 Jan 31;493(7434):632-7. doi: 10.1038/nature11800.
