This disclosure relates to a method of expressing the receptor-binding domain (RBD) region of the coronavirus SARS-CoV-2 Spike protein in a highly native form that is strongly reactive to natural antibodies induced upon SARS-CoV-2 infection or vaccination of humans and that more efficiently binds the angiotensin-converting enzyme 2 (ACE2) receptor. This method fuses the RBD to the C-terminus of an N-terminal fragment of the gp70 protein (the surface protein (SU) of the Friend57 strain of murine leukemia viruses). This method of expression enhances the native folding of the RBD and increases its recognition by antibodies present in immune sera and its ability to interact with the ACE2 receptor. Further disclosed are methods of using this form of RBD for various purposes.

Methods for treating and/or assessing a subject having a symptomatic multiple myeloma or a precursor thereof, where the methods involve characterizing a plasma cell dyscrasia (e.g., monoclonal gammopathy of undetermined significance, smoldering multiple myeloma, multiple myeloma, plasma cell leukemia) in a biological sample from a subject as being high, medium, or low risk by assigning to the plasma cell dyscrasia a multiple myeloma (MM)-like score. The methods may involve sequencing DNA from the biological sample using whole-genome sequencing (WGS).

In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to compounds (I) that are inhibitors for spleen tyrosine kinase (Syk), which is a key signaling protein in hematologic cells and implicated in multiple hematopoietic malignancies, cancer (e.g., chronic lymphoid leukemia (CLL) or acute myeloid leukemia (AML)), diabetes, and immune disorders. In one aspect, the compounds described herein drug resistance, which renders current ATP-competitive Syk inhibitors ineffective.

Methods of monitoring therapeutic efficacy in a subject with myelodysplastic syndrome (MDS) are provided. Also provided is a method of identifying a subject with MDS for treatment with a telomerase inhibitor, and methods of treating MDS. The methods include administering to the subject a telomerase inhibitor and assessing variant allele frequency (VAF) for one or more of the following genes: SF3B1, TET2, DNMT3A, ASXL1, and CUX1 in a biological sample obtained from the subject after administration of the telomerase inhibitor. In some cases, a 25% or more reduction in VAF identifies a subject who has an increased likelihood of benefiting from treatment with a telomerase inhibitor. In some instances, the telomerase inhibitor is imetelstat or imetelstat sodium.
