Transgenesis in Drug Discovery: Enhancing Target Identification and Validation.

Abstract

Transgenesis, the introduction of foreign genetic material into the genome of an organism, has become a crucial and transformative technique in the realm of drug discovery. This review article provides a comprehensive overview of the integral role that transgenesis plays in the drug discovery process, with a specific focus on target identification and target validation. By examining the recent advancements and innovative approaches, this article aims to shed light on the importance of transgenesis in accelerating drug development. In the context of target identification, transgenesis has allowed for the creation of relevant disease models, enabling researchers to study the genetic and molecular basis of various disorders. The use of transgenic animals, such as mice and zebrafish, has facilitated the identification of potential drug targets by mimicking specific human disease conditions. This review also discusses emerging technologies, such as CRISPR-Cas9 and other genome editing tools, which have revolutionized the field of transgenesis. These technologies have enhanced the precision and efficiency of genetic manipulations in transgenic animals, making the creation of disease-relevant models more accessible and cost-effective. Moreover, integration of omics technologies, such as genomics, transcriptomics, proteomics, and metabolomics, has provided a holistic view of the molecular changes in transgenic models, further aiding in target identification and validation. This review emphasizes the importance of transgenesis in target identification and validation and underscores its vital role in shaping the future of drug discovery.
