  • Patent number: 11679948
    Abstract: A sheet aligning mechanism includes first and second conveyance mechanisms disposed on first and second sides of a sheet conveyance path, respectively. A nip is formed between the first and second conveyance mechanisms. The first conveyance mechanism includes a first roller, a second roller, and a first conveyance belt wound around the first and second rollers. The first and second rollers are configured to rotate in a first direction along a sheet conveying direction for sheet conveyance, and stop rotation or rotate in a second direction opposite to the first direction for sheet alignment. The first conveyance belt includes an extended region between the first and second rollers in an extending direction inclined with respect to the sheet conveying direction, such that a width of the sheet conveyance path becomes narrower towards the nip in the sheet conveying direction.

The vif1 and vif2 peptides robustly suppress HAUSP DUB enzymatic activity, ultimately leading to p53-mediated anti-cancer activity. The vif1 and vif2 peptides, along with their homologues, are useful in treating cancer through regulation of p53 activity in a cancer cell. Also disclosed is the crystalline structure of vIRF4-HAUSP TRAF domain complex. The structure is useful in computer aided drug design for identifying an agent that interacts with and inhibits HAUSP, resulting in p53 medicated cell cycle arrest of cancer cells.

    Abstract: An in vitro system for generating sequence, and thus structural, diversity in proteins is described. The system can be constructed using appropriately selected nucleic acid molecules that encode regions of a selected protein or proteins and recombination signal sequences (RSS). The selected protein(s) can be, for example, immunoglobulin (Ig) V, D, J and/or C regions, regions of a non-immunoglobulin (non-Ig) protein, or a combination of Ig regions and non-Ig regions. Assembly of such appropriately selected components and their introduction into suitable recombination-competent host cells allows for recombination between the RSS sequences and introduction of sequence and structural diversity into the protein(s).

  • Publication number: 20130196430
    Abstract: The invention concerns the field of protein production and cell culture technology. CERT is identified as a novel in vivo PKD substrate. Phosphorylation on serine 132 by PKD decreases the affinity of CERT towards its lipid target phosphatidylinositol 4-phosphate at Golgi membranes and reduces ceramide transfer activity, identifying PKD as a regulator of lipid homeostasis. The present invention shows that CERT in turn is critical for PKD activation and PKD dependent protein cargo transport to the plasma membrane. The interdependence of PKD and CERT is thus a key to the maintenance of Golgi membrane integrity and secretory transport.

  • Publication number: 20130052728
    Abstract: The invention provides compositions for making erythroid progenitor cells that comprise in vitro-activated bone marrow mesenchymal stem cells and embryoid bodies (EBs) or pluripotent stem cells, and methods for making and using them, including ameliorating (e.g., preventing or treating) anemia and/or stimulating erythropoiesis. In one embodiment, the invention provides methods of increasing propensity of committed stem cell differentiation towards the erythroid lineage.

  • Publication number: 20120329151
    Abstract: An apparatus and method to maintain pH within a range conducive for cell growth in a bicarbonate-containing cell culture system without the addition of base. The method relies on the gas transfer characteristics of the bioreactor system to modulate the CO2 transfer to and from the cell culture such that the pH of the cell culture can be maintained within a desired range.

  • Publication number: 20120316114
    Abstract: The present disclosure provides variants of C-type natriuretic peptide (CNP), pharmaceutical compositions comprising CNP variants, and methods of making CNP variants. The CNP variants are useful as therapeutic agents for the treatment of diseases responsive to CNP, including but not limited to bone-related disorders, such as skeletal dysplasias (e.g., achondroplasia), and vascular smooth muscle disorders (e.g., restenosis and arteriosclerosis).

  • Publication number: 20120283136
    Abstract: This invention provides new combinatorial approaches for the biosynthesis and screening of cyclic peptides inside living cells. These novel approaches are useful for finding biologically relevant molecules, e.g., those able to inhibit the cytotoxicity of Anthrax Edema Factor. Key to this ‘living combinatorial’ approach is the use of a living cell as a micro-chemical factory for both synthesis and screening of potential inhibitors for a given molecular recognition event.
