  • Publication number: 20240115577
    Abstract: The present disclosure relates to compounds. and to their pharmaceutical compositions. that inhibit dipeptidyl peptidase IV (DPP4). Hie compounds selectively promote the proliferation of alveolar type 2 cells (AEC2s) and are useful in therapeutic methods of treating diseases whose etiology. for example. derives from epithelial degeneration and maladaptive remodeling, such as pulmonary' diseases like idiopathic pulmonary fibrosis (IFF), acute respiratory' distress syndrome (ARDS), and infant respiratory' distress syndromes (IRDS).

  • Publication number: 20230357766
    Abstract: The disclosure provides modified pegRNAs comprising one or more appended nucleotide structural motifs which increase the editing efficiency during prime editing, increase half-life in vivo, and increase lifespan in a cell. Modifications include, but are not limited to, an aptamer (e.g., prequeosim-1 riboswitch aptamer or “evopreQi-1”) or a variant thereof, a pseudoknot (the MMLV viral genome pseudoknot or “Mpknot-1”) or a variant thereof, a tRNA (e.g., the modified tRNA used by MMLV as a primer for reverse transcription) or a variant thereof, or a G-quadruplex or a variant thereof. The disclosure further provides prime editor complexes comprising the modified pegRNAs and having improved characteristics and/or performance, including stability, improved cellular lifespan, and improved editing efficiency.

  • Publication number: 20220033785
    Abstract: The disclosure provides programmable methylation “writers” and demethylation “erasers” for editing the methylation state of RNA targets, e.g., an RNA transcriptome. In particular, the disclosure provides RNA methylation editor polynucleotide contracts and vectors comprising (i) an RNA programmable RNA binding domain (RNApRNAbd); and (ii) an effector domain, wherein the effector domain is capable of adding or removing a methyl group in an RNA. The disclosed RNA methylation editor constructs are capable of achieving limited off-target modifications in RNA molecules. Further, the disclosure provides methods for making and using the programmable methylation editors to modifying the methylation state of RNA. The disclosure further provides complexes comprising a methylation writer protein and a guide RNA molecule and complexes comprising a demethylation eraser protein and a guide RNA molecule.

  • Patent number: 4714848
    Abstract: A method of electrically inducing mechanical precompression of a ferroelectric plate covered with electrodes utilizes the change in strains of the plate as functions of applied electric field. A first field polarizes and laterally shrinks the entire plate. An outer portion of the electrodes are removed, and an opposite field partially depolarizes and expands the central portion of the plate against the shrunk outer portion.
