Gene overexpression refers to a molecular biology technique in which the normal function of a gene is intensified, resulting in an increased production of a specific protein encoded by that gene. This method is often utilized in research settings to study the effects of gene amplification on cellular processes, gene regulation, and disease development. Gene overexpression can help researchers understand the function of specific genes, identify potential drug targets, and investigate the role of particular proteins in various biological pathways. It is commonly achieved through the use of gene expression vectors, which are DNA molecules that carry the gene of interest and can be introduced into cells to enable the overproduction of the corresponding protein.
