Novel compounds, compositions, and methods of using and preparing the same, which may be useful for treating alpha-1 antitrypsin deficiency (AATD) are disclosed.

The methods and compositions of the invention find use in the clinical diagnosis of cholestasis related syndromes, particularly PFIC types 1, 2, and 3; BRIC types 1 and 2; Alagille syndrome, and alpha1-antitrypsin deficiency. The compositions of the invention include isolated nucleic acid molecules and oligonucleotide pairs suitable for use in amplifying regions of cholestasis related genes. Compositions of the invention include a cholestasis related gene resequencing microarray suitable for determining the nucleotide sequence of a region of a cholestasis related gene. Knowledge of the nucleotide sequence of one or more regions of a patient's cholestasis related gene allows diagnosis of the patient's syndrome.

The invention relates to a RNA interference triggers for inhibiting the expression of an AAT gene through the mechanism of RNA interference. The invention also relates to a pharmaceutical composition comprising the AAT RNAi trigger together with an excipient capable of improving delivery of the RNAi trigger to a liver cell in vivo. Delivery of the AAT RNAi trigger to liver cells in vivo provides for inhibition of AAT gene expression and treatment of alpha 1-antitrypsin deficiency and associated diseases.

A novel alpha-1 antitrypsin variant, a method of preparing the same, and use thereof are provided. The alpha-1 antitrypsin variant has excellent stability in the body and maintains an inhibitory effect on elastase activities because the blood half-life (t1 / 2) and the area under blood drug concentration vs. time curve (AUC) are remarkably increased by adding an N-glycosylation site in animal cells through amino acid mutation between 1st and 25th positions of the N-terminus of alpha-1 antitrypsin. Therefore, the alpha-1 antitrypsin variant can be useful in preventing or treating alpha-1 antitrypsin deficiency.

The present invention relates to methods and compositions for modulating the unfolded protein response. The method further relates to methods and compositions for the treatment and diagnosis of protein conformational diseases or disorders, including, but not limited to, α1-antitrypsin deficiency, cystic fibrosis, and autoimmune diseases and disorders. The invention further provides methods for modulating the unfolded protein response by modulating XBP1 mRNA splicing.

The present invention relates to a method for treating chronic lung disease, in particular alpha-1 antitrypsin deficiency or emphysema caused by alpha-1 antitrypsin deficiency, with a neutrophil elastase inhibitor. The invention also relates to a pharmaceutical composition comprising a neutrophil elastase inhibitor.

Methods of treating liver diseases are provided. Accordingly there is provided a method of treating a liver disease selected from the group consisting of fatty liver disease and chronic liver rejection in a subject in need thereof, wherein said liver disease is not associated with genetic alpha-1 anti-trypsin (AAT) deficiency, the method comprising administering to the subject a therapeutically effective amount of AAT.

A chimeric protein that is a fusion construct of a series of functional domains is used to deliver a therapeutic agent to a human subject suffering from disease. In some embodiments, the chimeric protein includes a therapeutic region, a transportation region, and a cleavage region disposed between the therapeutic region and the transportation region. The transportation region allows the chimeric protein to be moved across a cellular membrane of an affected cell within the subject. Cleavage of the chimeric protein at the cleavage region once within the cell separates the therapeutic region from the transportation region, enabling the therapeutic region to function normally within the cell. The therapeutic region can be effective in the treatment of, for example, muscular dystrophy, diastrophic dysplasia, malignant melanoma, porphyria, alpha-1 antitrypsin deficiency, Aicardi-Goutieres syndrome, cystic fibrosis, progeria, Marfan syndrome, tuberous sclerosis, adrenoleukodystrophy, and the like.
