Gene silencing is a mechanism by which the expression of a gene is downregulated or inhibited, leading to a decrease in the production of the corresponding protein. This can be achieved through various mechanisms, such as RNA interference (RNAi) or the use of small molecules that target specific genes. Gene silencing has important applications in research, as it allows scientists to study the function of specific genes and their role in various biological processes. It also has potential therapeutic applications, as it can be used to treat genetic disorders or diseases by targeting and inhibiting the expression of disease-causing genes.
