Application

Insulin from porcine pancreas has been used:
  • for culturing of the primary tumors obtained from mice and porcine preantral follicles
  • to characterize hormones involved in postnatal chicken preadipocyte differentiation in vitro
  • to check the reduction ability of the Escherichia coli thiol disulfide exchange proteins (DsbA, DsbC, DsbG) towards insulin

Biochem/physiol Actions

Two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond. Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.

The objective of this study was to assess fertilization and embryonic development following intracytoplasmic sperm injection (ICSI) of oocytes from porcine preantral follicles matured in vitro. Also, another aim was to describe actin filament distribution during fertilization and embryonic development
