Gene expression profiling

Gene expression profiling is a technique used to measure the activity levels of thousands of genes at once. It helps scientists understand which genes are turned on or off in a particular cell type or condition, such as in health or disease. By analyzing the patterns of gene expression, researchers can gain insights into the functions of these genes and how they contribute to various biological processes. This method is valuable in fields like cancer research, where it can help identify disease mechanisms and potential treatment targets. Ultimately, it enhances our understanding of genetics and molecular biology.
