Programmable intracellular RNA scaffolds for integrating sensing and regulation

Co-transactionally folded RNA nanostructures in living cells.


Invention Summary:

Biomarker validation and intracellular RNA detection require tools that are precise, scalable, and capable of capturing complex gene expression patterns. Current approaches, including CRISPR-based systems, RNA interference, and RNA sponge technologies, are often limited by a single-target focus, reliance on protein components, off-target effects, or a lack of structural organization. These limitations restrict their ability to perform multiplex RNA sensing and pathway-level analysis in living cells, which is increasingly needed in diagnostics, drug discovery, and functional genomics.

Rutgers researchers have developed a novel RNA nanostructure platform that self-assembles inside living human cells, enabling programmable and multiplex interactions with RNA and protein targets. Unlike existing RNA technologies, these co-transcriptionally folded RNA lattices form ordered, stable nanostructures that can integrate multiple functional modules, including sensing and binding domains, such as the KRAS proto-oncogene associated with pancreatic and colorectal cancers. This platform enables simultaneous detection and modulation of multiple intracellular targets, providing a new approach for studying complex biological pathways and developing next-generation diagnostic and therapeutic strategies.

Market Applications:

  • Multiplex RNA sensing for biomarker detection in cancer and other diseases
  • Cell-based assay platforms for drug discovery and pathway analysis
  • Functional genomics tools for studying gene regulatory networks
  • Future applications in therapeutic targeting of oncogenic pathways

Advantages:

  • Multiplex capability - simultaneous targeting of multiple RNAs and proteins
  • Ordered nanostructure architecture - improved stability and reduced crosstalk
  • Protein-free system - avoids delivery and regulatory challenges of CRISPR-based systems
  • Nuclear retention - enables interaction with transcriptional and regulatory processes
  • Modular and programmable design - adaptable to different targets and applications
