Described are nucleic acid regulatory elements that are able to enhance liver-specific expression of genes, methods employing these regulatory elements and uses of these elements. Expression cassettes and vectors containing these nucleic acid regulatory elements are also disclosed. These are particularly useful for applications using gene therapy.

Disclosed are knottin peptides containing non-natural amino acids so that they can be formed by chemical conjugation into two or more knottin monomers. The knottin monomers comprise a non-natural amino acid such as an aminooxy residue within the polypeptide sequence. The exemplified dimers were produced by oxime formation between two aldehyde groups present on a polyether linker and an aminooxy functional group that was site-specifically incorporated the knottin. Knottins variants based on EETI (Ecballium elaterium trypsin inhibitor) and AgRP (Agouti-related protein) were engineered to contain integrin-binding loops. These dimers were shown to have increased binding strength to integrins on U87MG tumor cells, achieving significant increases in inhibition of cell adhesion and proliferation. Also disclosed are knottin monomers comprising an aminooxy residue; these may be conjugated to molecules such as doxorubicin.

The present invention relates to the finding of methods to shift the glycosylation profile of recombinant produced semm glycoproteins to the predominant bi-antennary form found in human plasma. This is accomplished by providing a mammalian cell line according to the invention with a series of gene disruptions and/or gene insertions that facilitate this shift.

Use of aprotinin as a carrier to produce a recombinant protein, polypeptide or peptide in algae The present invention relates to the use of aprotinin as a carrier to produce a recombinant protein, polypeptide or peptide in algae, in particular microalgae, wherein aprotinin and said recombinant protein, polypeptide or peptide are fused together to form a fusion protein. It also relates to a method to produce a recombinant protein, polypeptide or peptide in algae, wherein said method comprises genetic transformation of algae, in particular microalgae, with a recombinant nucleic acid sequence encoding a fusion protein, wherein said fusion protein comprises aprotinin and said recombinant protein, polypeptide or peptide. It further relates to a recombinant algae comprising a recombinant nucleic acid sequence encoding a fusion protein, wherein said fusion protein comprises aprotinin and a recombinant protein, polypeptide or peptide. The use of said recombinant algae, for producing said fusion protein is also contemplated.

The present invention provides a novel peptide that has an amino acid sequence represented by SEQ ID NO: 18, and binds to an active protease but does not bind to a pro-protease.
