Patent DE-4005062-A1 (DE)
Title: Mammary-derived Growth Inhibitor peptide(s) - and antibodies useful in bio technology and medicine as proliferation inhibitors e.g. of carcinoma cells
Inventor: GROSSE RICHARD PROF DR
IPC: C07K14/475
Filed: 1990-02-15
Abstract: Antibodies to biologically active peptides are claimed. The peptides, which are also cliamed, comprise partial sequences of the proliferation inhibitor mammary-derived growth inhibitor (MDGI). Peptide sequences are as follows: Peotide A (amino acids 69-78 of MDGI) EFDETTADDR. Peptide B (amino acids 121-131 of MDGI) TAVCTRVYEKQ. Peptide C (modified B) TRVCTRVYEKQ. Peptide D (modified B) TAVSTRVYEKQ. Also claimed is a method for the prodn.  of the antibodies by coupling the peptides to a carrier via a crosslinking agent, immunising a laboratory animal with the peptide construct, extracting antiserum, isolating the IgG fraction and isolating the specific antibodies by affinity chromatography. USE/ADVANTAGE - Useful in the study of the activity of MDGI (and related proteins), and have potential in the development of  similar proliferation regulators. The peptides have in vitro proliferation inhibiting activity against mammalian epithelial cells, a desensitising effect on coronary musculature and a beta-adrenergic effect. In an example, the inhibitory activity of peptide B is determined by measuring teh increase of carcinoma cells over 24 hrs. in the presence/absence of the peptide. At 10 power(-8) M inhibition is 17.1%, and at 10 power(-6) M inhibition is 33.3%. Addn. of insulin or cytidineoxyriboside reverses this activity.
