In Vitro Silencing of lncRNAs Using LNA GapmeRs.

Methods Mol Biol 2021 ;2348:157-166

Department of Experimental and Clinical Medicine, Magna Graecia University of Catanzaro, Catanzaro, Italy.

Despite substantial advancements have been achieved in the identification of long noncoding RNA (lncRNA) molecules, many challenges still remain into their functional characterization. Loss-of-function approaches are needed to study oncogenic lncRNAs, which appear more difficult to knock down by RNA interference as compared to mRNAs. In this chapter, we present a protocol based on the use of a novel class of antisense oligonucleotides, named locked nucleic acid (LNA) GapmeRs, to inhibit the oncogenic lncRNA NEAT1 in multiple myeloma cells.

Drug and Solute Transporters in Mediating Resistance to Novel Therapeutics in Multiple Myeloma.

ACS Pharmacol Transl Sci 2021 Jun 15;4(3):1050-1065. Epub 2021 Apr 15.

College of Medicine and Public Health, Flinders University, Bedford Park, South Australia 5042, Australia.

Multiple myeloma remains an incurable malignancy of plasma cells. Novel therapies, notably proteasome inhibitors and immunomodulatory drugs, have improved the survival of multiple myeloma patients; however, patients either present with, or develop resistance to, these therapies. Resistance to traditional chemotherapeutic agents can be caused by cellular drug efflux via adenosine triphosphate (ATP)-binding cassette (ABC) transporters, but it is still not clear whether these transporters mediate resistance to proteasome inhibitors and immunomodulatory drugs in multiple myeloma.
