  • Patent number: 11582957
    Abstract: The invention relates to a genetically modified mouse comprising a heterozygous mutation of Tardbp (TDP-43) gene in that the Asn at amino acid 390 in TDP-43 is substituted with an amino acid that is different from Asn, wherein the genetically modified mouse exhibits Amyotrophic lateral sclerosis (ALS)-like phenotypes, TDP-43 proteinopathies and/or motor neuron degeneration. The invention also so relates to an isolated spinal cord motor neuron differentiated from an embryonic stem cell (ESC) that is obtained from an offspring of a genetically modified mouse according to the invention. Methods for identifying an agent alleviating and/or suppressing ALS-TDP pathogenesis are also disclosed.

  • Publication number: 20220152036
    Abstract: Provided herein are compounds of Formula (I). The compounds described herein are useful in treating a disease associated with the expression of endogenous embryonic/fetal globin (e.g., ? globin) in erythrocytes (e.g., treating ?-thalassemia and/or sickle cell disease through at least the induction of the globin gene expression in erythrocytes), and/or anemia (?-thalassemia and/or sickle cell anemia). The compounds described herein are useful in treating, delaying, and/or preventing the adverse effects of ?-thalassemia and/or sickle cell disease, inducing ? globin production, and/or inducing the expression of embryonic/fetal globin genes in a subject, cell, tissue, or biological sample. Also provided in the present disclosure are pharmaceutical compositions, kits, and methods of using the compounds for inducing ? globin production described herein and for treating any of the target diseases described herein.
