Incorporation of Viral RNA Elements for Increased mRNA Stability Within Mammalian Cells to Prolong Nanobody Production

Ramankutty, Rhea; Branda, Steven S.; Jones, Rachel A.; Bays, Nathan R.

The development of protein-based pharmaceuticals has taken place for years, often finding roadblocks relevant to in vitro biomanufacturing, drug delivery, and drug half-life. Industrial and national laboratory focus has now shifted to messenger RNA (mRNA)-based pharmaceuticals, as mRNA can be manufactured and delivered more easily, and can lead to direct intracellular protein production. Artificial stabilization of the naturally transient mRNA is needed to prolong protein production by recipient cells. Incorporation of viral genome elements known as exoribonuclease-resistant RNA (xrRNA) should allow for this stabilization. To evaluate the effects of xrRNA on mRNA stability, fluorescent proteins are encoded within the mRNA of interest for easier detection through immunocytochemistry, microplate reader screening, and high-content confocal microscopy. As seen with the Pfizer and Moderna COVID 19 vaccines, mRNA-based medical countermeasures can be powerful tools in service of public health and biodefense, and our work to improve mRNA stability should further enhance this promising new approach to medicine.
