The 42nd anniversary of FDA approval for human insulin synthesized via genetic engineering marks a pivotal moment in biotechnology, launching a revolutionary era in drug development. This milestone, covered extensively in the press, addressed a critical need for diabetes treatment, transitioning from animal-derived insulin to human-identical insulin produced in bacteria. The rapid approval process, despite initial bureaucratic hesitations, demonstrated the scientific and commercial viability of recombinant DNA technology, significantly impacting the biotechnology industry. However, the current drug approval process remains lengthy and costly, highlighting the need for regulatory improvements.
