    摘要: An isolated chimeric GLP-1 nucleic acid sequence encoding a human pro-insulin leader, a glucagon-like peptide-1 (GLP-1), and a furin cleavable site between the human pro-insulin leader sequence and the GLP-1 is provided. Also provided is an isolated modified chimeric GLP-1 nucleic acid sequence encoding a human pro-insulin leader, a glucagon-like peptide-1 (GLP-1), and a furin cleavable site between the human pro-insulin leader sequence and the GLP-1. Recombinant expression vectors comprising the chimeric GLP-1 nucleic acid sequences, which produce GLP-1 constitutively are provided, as are human cells transfected with such an expression vector in combination with an expression vector comprising a proinsulin nucleic acid sequence and an expression vector comprising a furin and a glucose-regulatable TGF-alpha promoter. Methods of producing human GLP-1 constitutively are provided as are method of producing GLP-1 and insulin or in a glucose-dependent manner using such transfected cells. Methods of treating a subject having Type II diabetes and methods of treating a subject prone to hyperglycemia or suffering from hyperglycemia are provided in which transfected cells produce human GLP-1 and insulin in a glucose-dependent manner. Also provided are methods of reducing weight in a subject by implanting into the subject transfected cells which produce human GLP-1 and insulin in a glucose-dependent manner.

    摘要: The present invention relates to a process for preparing human proinsulin which is represented as a following chemical formula(I): ##STR1## wherein, R is an amino acid residue or a peptide which is degradable enzymatically or chemically; and, X is a linkage of an amino group of A-1 in insulin A chain and a carboxyl group of B-30 in insulin B chain which can be separated from the A chain or the B chain enzymatically or chemically, provided that a region from A-1 to A-21 is the insulin A chain and a region from B-1 to B-30 is the insulin B chain. In accordance with the present invention, human recombinant insulin precursor can be simply manufactured with a good reproducibility, since dissolution, sulfonation, concentration, desalting and purification are remarkably simplified, while increasing the yield of refolding reaction.

    摘要: The present invention provides a method for manufacture of proinsulin with high export yield, by modifying the connecting peptide region of the proinsulin. According to the method of the present invention, the highest export yield of proinsulin can be obtained, when its connecting peptide region is similar in size to that of human insulin-like growth factor I(hIGFI) or when most of the connecting peptide region of the proinsulin is deleted.

    摘要: Analogs of human insulin containing an aspartic acid at position 1 of the B chain (Asp.sup.B1), and optionally, having a gln modification at position 13 (Gln.sup.B13), display modified physico-chemical and pharmacokinetic properties which enable them to be long acting. These analogs are useful in the treatment of hyperglycemia because they are soluble and display an increased tendency to self-associate.
