Long noncoding RNAs (lncRNAs) make up the largest portion of RNA produced from the human genome, but only a small fraction have any ascribed functions. Although the role of protein-coding genes in macrophage biology has been studied extensively, our understanding of the role played by lncRNAs in this context is still in its early stages. There are over 20,000 lncRNAs in the human genome therefore, attempting to select a lncRNA to characterize functionally can be a challenge. Here we describe two approaches to identify and functionally characterize lncRNAs involved in monocyte-to-macrophage differentiation. The first involves the use of RNA-seq to infer possible functions and the second involves a high throughput functional screen. We examine the advantages and disadvantages of these methodologies and the pipelines for validation that assist in determining functional lncRNAs.
