Abstrakt: The human genome contains thousands of long noncoding RNAs (lncRNAs), even outnumbering protein-coding genes. These molecules can play a pivotal role in the development and progression of human disease, including cancer, and are susceptible to therapeutic intervention. Evidence of biologic function, however, is still missing for the vast majority of them. Both loss-of-function (LOF) and gain-of-function (GOF) studies are therefore necessary to advance our understanding of lncRNA networks and programs driving tumorigenesis. Here, we describe a protocol to perform lncRNA's LOF or GOF studies in multiple myeloma (MM) cells, using CRISPR interference (CRISPRi) or CRISPR activation (CRISPRa) technologies, respectively. These approaches have many advantages, including applicability to large-scale genetic screens in mammalian cells and possible reversibility of modulating effects; moreover, CRISPRa offers the unique opportunity to enhance lncRNA expression at the site of transcription, with relevant biologic implications.
