The invention relates to an adeno-associated virus (AAV) vector comprising a nucleic acid construct for the expression of a glucose-6-phosphatase-a (G6Pase-a) in a cell, the construct comprising a nucleic acid sequence encoding the G6Pase-a, wherein the nucleic acid sequence encoding the G6Pase-a is operably linked to a human alpha-1 antitrypsin (hAAT) promoter, a cell transformed with the vector of the invention, a composition comprising the vector or the cell of the invention, and the use thereof.

The technology provided herein relates to novel isolated polypeptides and peptides having a growth inhibitory effect on human cancer cells. Nucleic acid molecules encoding said polypeptides/peptides, vectors, host cells containing the nucleic acids and methods for preparation and producing said polypeptides/peptides. Compositions and methods for using such polypeptides/peptides for the prevention and treatment of cancer are also encompassed by the present disclosure.

The invention features methods for treating or preventing pulmonary diseases, including acute respiratory distress syndrome (ARDS) and pneumonia, in a subject in need thereof that involve administering to the subject inter-alpha inhibitor proteins (IαIps), including, e.g., inter-alpha inhibitor (IαI) and/or pre-alpha inhibitor (PαI).

A2M polypeptide compositions containing a non-natural bait region are disclosed. Methods of producing wild-type and variant A2M polypeptides and polynucleotides containing a non-natural bait region are also disclosed. The bait regions of the variant A2M polypeptides demonstrate enhanced protease inhibitory characteristics compared to wild-type A2M. Variant A2M polypeptides that demonstrate longer half-lives upon administration to an organism compared to wild-type A2M are disclosed. The A2M compositions are useful in treating a number of diseases and conditions including inflammation, chronic wounds, and diseases with a pathology associated with proteases.

Disclosed are compositions and method related to variants of SPINK2 that bind to targets other than an endogenous target of SPINK2. In one embodiment, a peptide is provided that comprises the amino acid sequence SEQ ID NO: 1. In further embodiments, an amino acid sequences encoded by nucleotide positions 4 to 42 and/or nucleotide positions 94 to 189 in the nucleotide sequence of SEQ ID NO: 14 flank the amino terminus and the carboxyl terminus, respectively, of the amino acid sequence. In another embodiment, a peptide is provided that comprises an amino acid sequence derived from the amino acid sequence of SEQ ID NO: 1 in which a conservative substitution, deletion, addition and/or insertion of 1 to 5 (inclusive) amino acids has occurred at amino acids other than the 1st Xaa to the 12th Xaa counting from the amino terminus.

The present invention relates to cell lines that are genetically modified to overexpress a β-galactoside α-2,3-sialyltransferase 1 (ST3Gal1), preferably human ST3Gal1, which can be used for the production of recombinant glycoproteins having highly or fully sialylated O-linked GalNAc glycans (GalNAc O-glycans), preferably core 1 GalNAc O-glycans, as well as to respective recombinant glycoproteins. Further, the present invention relates to respective methods of expressing recombinant glycoproteins, methods of increasing the degree of sialylation of recombinant glycoproteins, and methods of decreasing the micro-heterogeneity of GalNAc O-glycans.
