What is the Origin of Recombinant DNA Peptides?

The term originates from the revolutionary field of genetic engineering and biotechnology, where recombinant DNA refers to DNA molecules formed by combining genetic material from multiple sources. The first successful production of a human hormone using this method, recombinant human insulin, marked the birth of this technology in the 1970s. This process enabled the large-scale, safe production of human-sequence hormones previously sourced from animal organs.

What is the Mechanism of Recombinant DNA Peptides?

The mechanism of production involves isolating the gene encoding the peptide, inserting this DNA sequence into a bacterial plasmid or viral vector, and then introducing this recombinant DNA into a host cell. The host cell's cellular machinery, including ribosomes and transfer RNA, then reads the foreign DNA and translates it into the desired peptide. The peptide is subsequently harvested, purified, and formulated for clinical use, where its therapeutic mechanism is identical to the endogenous hormone it mimics.

Recombinant DNA Peptides

Meaning

Recombinant DNA Peptides are short-chain amino acid sequences, or polypeptides, that are produced artificially by genetically engineering a host organism, typically bacteria or yeast, to express the gene sequence encoding the desired peptide. These therapeutic agents, which include analogs of natural human hormones like insulin and growth hormone, are characterized by high purity, consistent batch-to-batch quality, and a structure identical or highly similar to the native human peptide.
