mRNA stability is a research area within molecular biology that focuses on understanding the factors and mechanisms that regulate the lifespan of messenger RNA molecules in cells. mRNA stability is important for controlling gene expression and protein production, as it determines how long a particular mRNA molecule will remain intact and available for translation into protein. Research in this area aims to uncover the molecular mechanisms that influence mRNA stability, such as RNA-binding proteins, microRNAs, and RNA degradation pathways. Understanding mRNA stability can provide insights into disease mechanisms, developmental processes, and cellular responses to environmental stimuli.
