Description: Overexpression is the biological process by which a gene is expressed at higher than normal levels, resulting in excessive production of proteins or gene products. This phenomenon can be induced by various factors, including changes in the cellular environment, epigenetic modifications, or the introduction of external genetic elements. Overexpression is a crucial aspect of genetic regulation, as it allows cells to adapt to changing conditions and respond to external stimuli. In the context of bioinformatics, overexpression is studied through gene expression analysis, where techniques such as RNA sequencing and microarrays are used to quantify the expression levels of multiple genes simultaneously. This process is fundamental to understanding genetic regulatory networks and the interactions between different genes, as well as identifying biological markers in diseases. Overexpression can have significant implications in biomedical research, as it may be associated with various pathologies, including cancer and metabolic diseases, where abnormal regulation of gene expression plays a key role in disease progression.
