Transgenic

Transgenic describes organisms containing foreign genetic material stably integrated into their genomes, inherited through germline transmission, created through genetic engineering techniques introducing genes from other species or synthetic sequences. These genetically modified organisms exhibit novel traits encoded by transgenes, ranging from simple reporter gene expression to complex metabolic pathways or disease models.

The pharmaceutical industry employs transgenic organisms across multiple applications. Transgenic animals model human diseases, expressing mutant human genes causing pathology enabling therapeutic testing and mechanistic studies. Humanised mice carry human immune system components or drug targets improving preclinical model relevance. Production animals including goats, rabbits, or chickens express therapeutic proteins in milk or eggs offering alternative manufacturing platforms. Transgenic cell lines produce recombinant proteins with mammalian post-translational modifications. Target validation employs transgenic models confirming gene roles in disease. Safety assessment uses transgenic reporter mice detecting genotoxicity or carcinogenicity. Regulatory frameworks address transgenic organisms used in research or production, requiring containment preventing environmental release. As genome editing enables more precise modifications and applications expand through novel formats, transgenic technology continues providing valuable research models, production platforms, and tools supporting pharmaceutical development.
