This present disclosure provides recombinant adeno-associated virus (rAAV) and methods of their use in gene therapy for treating propionic acidemia (PA). Also provided are pharmaceutical compositions comprising a rAAV of the invention and a pharmaceutically acceptable carrier or excipient. These pharmaceutical compositions may be useful in gene therapy for the treatment of PA caused by a mutation in propionyl-CoA carboxylase α-subunit (PCCA) or a mutation in propionyl-CoA carboxylase β-subunit (PCCB).

This document provides butyrylcholinesterases having an enhanced ability to hydrolyze acyl ghrelin as well as nucleic acids encoding such butyrylcholinesterases. This document also provides methods and materials for treating obesity and/or aggression. For example, methods for administering a nucleic acid encoding a wild-type or mutant butyrylcholinesterase having the ability to hydrolyze acyl ghrelin to a mammal under conditions wherein the level of acyl ghrelin within the mammal is reduced, under conditions wherein the rate of body weight gain of the mammal is reduced, under conditions wherein the mammal's level of aggression is reduced, and/or under conditions wherein the mammal's rate of developing stress-induced tissue damage are provided.

Provided herein are methods and related compositions for administering viral transfer vectors and antigen-presenting cell targeted immunosuppressants.

The present invention relates to an AAV vector carrying a predetermined hybrid HGF gene sequence. Use of the AAV vector of the present invention allows a hybrid HGF gene to be delivered to a subject at a high delivery yield.

The present invention relates to peptides and compositions for use in improving transduction efficiency of viruses into target cells.

Provided is a method for targeted editing of target RNA containing a G to A mutation in a USH2A gene transcript based on LEAPER technology, comprising: introducing a construct of an adenosine deaminase recruiting RNA (arRNA) for editing the target RNA or a construct encoding said arRNA into a cell, wherein the arRNA comprises a complementary RNA sequence that hybridizes to the target RNA, and wherein the arRNA is capable of recruiting adenosine deaminase acting on RNA (ADAR), so that the target adenosine in the target RNA is deaminated, thereby performing in vivo editing of the base from A to I on RNA safely and effectively, repairing a pathogenic mutation site, and achieving the purpose of treating disease such as Usher syndrome.

The present invention relates to adeno-associated viral vector useful for transducing adipose tissue. The invention also relates to polynucleotides, plasmids, vectors and methods for the production of such adeno-associated viral vector. The invention also relates to gene therapy methods useful for the treatment of a disease that requires the regulation of the expression levels of a gene.

Disclosed herein are methods and compositions for targeted, nuclease-mediated insertion of transgene sequences into the genome of a cell.

This document provides butyrylcholinesterases having an enhanced ability to hydrolyze acyl ghrelin as well as nucleic acids encoding such butyrylcholinesterases. This document also provides methods and materials for treating obesity and/or aggression. For example, methods for administering a nucleic acid encoding a wild-type or mutant butyrylcholinesterase having the ability to hydrolyze acyl ghrelin to a mammal under conditions wherein the level of acyl ghrelin within the mammal is reduced, under conditions wherein the rate of body weight gain of the mammal is reduced, under conditions wherein the mammal’s level of aggression is reduced, and/or under conditions wherein the mammal’s rate of developing stress-induced tissue damage are provided.

Methods are provided for the prognosis, diagnosis and treatment of various pathological states, including cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. The methods provided herein are based on the discovery that various proteins with a high level of sialylation are shown herein to be associated with disease states, such as, cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. Such methods provide a lysosomal exocytosis activity profile comprising one or more values representing lysosomal exocytosis activity. Also provided herein, is the discovery that low lysosomal sialidase activity is associated with various pathological states. Thus, the methods also provide a lysosomal sialidase activity profile, comprising one or more values representing lysosomal sialidase activity. A lysosomal sialidase activity profile is one example of a lysosomal exocytosis activity profile.
