MicroRNA Profiling of Alzheimer's Disease Cerebrospinal Fluid

MicroRNAs (miRNAs) are a class of small, highly conserved, and noncoding RNAs that modulate gene expression by regulating the activity and stability of target mRNAs. MiRNAs play significant roles by controlling fundamental cellular processes and its deregulation is associated with various diseases. Ubiquitous expression and its release into circulation make them interesting biomarkers, which can be measured by different platforms. In this book chapter, we provide a specific protocol that describes the detection of circulating miRNAs in CSF by using RT-qPCR.
