The purpose of the present invention is to provide a simple and highly accurate method for detecting pancreatic exocrine dysfunction with minimal invasiveness to a subject. The method comprising in vitro measurement of two APOA2 protein variants, mutants thereof and/or fragments thereof in a body fluid sample derived from the subject and detection of the presence or absence of pancreatic exocrine dysfunction on the basis of the measured amounts, and a detection kit for pancreatic exocrine dysfunction including antibodies that can specifically bind to said proteins are provided.

The disclosure relates, in some aspects, to compositions and methods for treatment of neurodegenerative disease, for example Alzheimer's disease. In some embodiments, the disclosure provides expression constructs comprising a transgene encoding an APOE protein isoform or a portion thereof, an inhibitory nucleic acid targeting an APOE gene or a portion thereof, or any combination of the foregoing. In some embodiments, the disclosure provides methods of treating Alzheimer's disease by administering an expression construct to a subject in need thereof.

A fusion protein which may comprise a first nCas9 fragment, a chimeric insertion fragment, a second nCas9 fragment and two UGI fragments from N-terminus to C-terminus, wherein the chimeric insertion fragment is selected from APOBEC1 fragment or APOBEC3A fragment for cytosine deamination at the target site. The fusion protein may comprise a first nCas9 fragment, a chimeric insertion fragment and a second nCas9 fragment from N-terminus to C-terminus, wherein the chimeric insertion fragment is TadA-TadA* for cytosine deamination at the target site. The present disclosure provides a novel base editing tool that is compatible with insertion of various deaminases on the chimeric sites of nCas9. Compared with nCas9 terminal fusion base editor, the base editing tool of the present invention significantly reduce off-targeting on both DNA and RNA, while maintaining specific targeted base editing efficiency, with higher specificity and favorable industrialization prospects.

Disclosed herein is the use of CER-001, a negatively charged lipoprotein complex which comprises recombinant human apolipoprotein A-I (ApoA-I), sphingomyelin (SM), and 1,2-dihexadecanoyl-sn-glycero-3-phospho-(1′-rac-glycerol) (Dipalmitoylphosphatidyl-glycerol; DPPG) for treating kidney diseases, and methods for treating a subject having kidney diseases with CER-001. For example, the kidney disease can be associated with a lecithin cholesterol acyl transferase (LCAT) deficiency.
