Abstract: Protein double-shell nanostructures comprising apoferritin for carrying cargo proteins of interest are provided. Such nanostructures can be used to increase rigidity of a cargo protein of interest to allow structures of small and flexible proteins to be determined by cryogenic-electron microscopy (cryo-EM). Recombinant vectors for producing protein double-shell nanostructures are also provided. The nanostructures described herein may find use in various applications in research and drug discovery.

Abstract: Methods of treating a subject for a bone marrow failure syndrome, e.g., DBA, are provided. Aspects of the methods include administering to the subject an effective amount of a Nemo-Like Kinase (NLK) inhibitor. Also provided are compositions that find use in practicing embodiment of the invention.

Abstract: Compounds and methods are provided for inhibiting a CREB-CBP protein-protein interaction in a sample. In some cases, the method includes modulating transcription of CREB in a cell that overexpresses CREB. Also provided are methods of inhibiting the proliferation of a cancer cell. The subject CREB transcription inhibitor compounds include a substituted salicylamide or a prodrug thereof. Methods of alleviating symptoms associated with cancer (e.g., Acute Myeloid Leukemia (AML) or Acute Lymphomblastic Leukemia (ALL)) in a subject in need thereof are also provided. Pharmaceutical compositions including the subject compounds find use in treating cancer. The subject compounds may be formulated or provided to a subject in combination with a second agent, e.g. an anticancer agent.
