    Binding of the Wilms' tumor locus zinc finger protein to the EGR-1 consensus sequence (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-30
    Description: The Wilms' tumor locus (WTL) at 11p13 contains a gene that encodes a zinc finger-containing protein that has characteristics of a DNA-binding protein. However, binding of this protein to DNA in a sequence-specific manner has not been demonstrated. A synthetic gene was constructed that contained the zinc finger region, and the protein was expressed in Escherichia coli. The recombinant protein was used to identify a specific DNA binding site from a pool of degenerate oligonucleotides. The binding sites obtained were similar to the sequence recognized by the early growth response-1 (EGR-1) gene product, a zinc finger-containing protein that is induced by mitogenic stimuli. A mutation in the zinc finger region of the protein originally identified in a Wilms' tumor patient abolished its DNA-binding activity. These results suggest that the WTL protein may act at the DNA binding site of a growth factor-inducible gene and that loss of DNA-binding activity contributes to the tumorigenic process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauscher, F J 3rd -- Morris, J F -- Tournay, O E -- Cook, D M -- Curran, T -- CA0917-15/CA/NCI NIH HHS/ -- CA10817/CA/NCI NIH HHS/ -- CA23413/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1259-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2244209" target="_blank"〉PubMed〈/a〉

    Transcriptional repression mediated by the WT1 Wilms tumor gene product (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-10-07
    Description: The wt1 gene, a putative tumor suppressor gene located at the Wilms tumor (WT) locus on chromosome 11p13, encodes a zinc finger-containing protein that binds to the same DNA sequence as EGR-1, a mitogen-inducible immediate-early gene product that activates transcription. The transcriptional regulatory potential of WT1 has not been demonstrated. In transient transfection assays, the WT1 protein functioned as a repressor of transcription when bound to the EGR-1 site. The repression function was mapped to the glutamine- and proline-rich NH2-terminus of WT1; fusion of this domain to the zinc finger region of EGR-1 converted EGR-1 into a transcriptional repressor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Madden, S L -- Cook, D M -- Morris, J F -- Gashler, A -- Sukhatme, V P -- Rauscher, F J 3rd -- CA-0917-15/CA/NCI NIH HHS/ -- CA-23413/CA/NCI NIH HHS/ -- CA-52009/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Sep 27;253(5027):1550-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute of Anatomy and Biology, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1654597" target="_blank"〉PubMed〈/a〉

    Genetic diversity of tumors with mismatch repair deficiency influences anti-PD-1 immunotherapy response (2019)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2019
    Description: 〈p〉Tumors with mismatch repair deficiency (MMR-d) are characterized by sequence alterations in microsatellites and can accumulate thousands of mutations. This high mutational burden renders tumors immunogenic and sensitive to programmed cell death–1 (PD-1) immune checkpoint inhibitors. Yet, despite their tumor immunogenicity, patients with MMR-deficient tumors experience highly variable responses, and roughly half are refractory to treatment. We present experimental and clinical evidence showing that the degree of microsatellite instability (MSI) and resultant mutational load, in part, underlies the variable response to PD-1 blockade immunotherapy in MMR-d human and mouse tumors. The extent of response is particularly associated with the accumulation of insertion-deletion (indel) mutational load. This study provides a rationale for the genome-wide characterization of MSI intensity and mutational load to better profile responses to anti–PD-1 immunotherapy across MMR-deficient human cancers.〈/p〉

    The pressure moments for two rigid spheres in low-Reynolds-number flow (1993)
    New York, NY : American Institute of Physics (AIP)

    Notes: The pressure moment of a rigid particle is defined to be the trace of the first moment of the surface stress acting on the particle. A Faxén law for the pressure moment of one spherical particle in a general low-Reynolds-number flow is found in terms of the ambient pressure, and the pressure moments of two rigid spheres immersed in a linear ambient flow are calculated using multipole expansions and lubrication theory. The results are expressed in terms of resistance functions, following the practice established in other interaction studies. The osmotic pressure in a dilute colloidal suspension at small Péclet number is then calculated, to second order in particle volume fraction, using these resistance functions. In a second application of the pressure moment, the suspension or particle-phase pressure, used in two-phase flow modeling, is calculated using Stokesian dynamics and results for the suspension pressure for a sheared cubic lattice are reported.

    Notes: Summary A combination of immunocytochemistry at light and electron microscopic levels, direct radioimmunoassay and measurement after gel chromatography have been used to identify and characterise a glucagon-like peptide detected in human foetal stomach. Immunocytochemistry, with region specific antisera, demonstrated that the glucagon-containing cells were indistinguishable from pancreatic A cells. Radioimmunoassay of tissue extracts confirmed the presence of significant quantities of glucagon, mean 21 pmol/g wet weight (range 14–29) in 16–26 week old foetuses, increasing to 41 pmol/g wet weight (range 31–52) in 33–30 week old foetuses and after gel chromatography the peptide was found to elute at the same position as standard porcine glucagon. It is apparent, therefore, that the human foetal fundus contains significant quantities of true pancreatic-type glucagon.
