The significance of miRNAs in disease

MicroRNAs (miRNAs) are small molecules that help regulate how genes are expressed in our cells. They play a crucial role in maintaining normal biological functions. When miRNAs malfunction or their levels are abnormal, it can lead to diseases like cancer, heart problems, or neurological conditions. By controlling gene activity, miRNAs can influence cell growth, death, and communication. Scientists are studying miRNAs because they hold potential for developing new diagnostic tools and therapies, offering hope for earlier disease detection and more targeted treatments.
