背景信息

**Background of GH Recombinant Proteins**

Growth hormone (GH), also known as somatotropin, is a peptide hormone critical for growth, metabolism, and cellular repair. Naturally produced by the anterior pituitary gland, GH stimulates tissue growth through indirect mechanisms mediated by insulin-like growth factor 1 (IGF-1). Historically, GH extracted from human or animal sources was used therapeutically but posed risks of immunogenicity and pathogen transmission, notably in cases linked to Creutzfeldt-Jakob disease.

The advent of recombinant DNA technology in the 1980s revolutionized GH production. Recombinant GH (rGH) is synthesized by inserting the human GH gene into host systems like *E. coli*, yeast, or mammalian cells, enabling large-scale, pathogen-free production. The first recombinant GH, approved by the FDA in 1985. replaced cadaver-derived GH, enhancing safety and accessibility for treating growth disorders such as pediatric growth hormone deficiency and Turner syndrome.

Structurally, rGH mirrors endogenous GH—a 191-amino-acid single-chain polypeptide—but may exhibit slight post-translational variations depending on the host system. Advances in protein engineering, such as pegylation or fusion proteins, have further optimized its pharmacokinetics and therapeutic efficacy.

Beyond growth disorders, rGH is used in metabolic conditions, muscle-wasting diseases, and anti-aging therapies, though misuse in sports remains controversial. Safety concerns, including fluid retention and glucose intolerance, necessitate strict clinical oversight.

Ongoing research focuses on improving delivery systems (e.g., long-acting formulations) and exploring novel applications in tissue regeneration. As a cornerstone of biopharmaceutical innovation, GH recombinant proteins exemplify the transformative potential of biotechnology in medicine.
