Challenges of CRISPR/Cas9 applications for long non-coding RNA genes

lncRNA

Long non-coding RNAs (lncRNAs) represent a large subgroup of RNAs that are over 200 nucleotides long and have a limited protein-coding potential. They play an important role in diverse cellular processes by regulating the gene expression at transcriptional or post-transcriptional levels. This ability of lncRNAs to modulate gene expression renders them indispensable for normal development CRISPRs (Clustered Regularly Interspaced Palindromic ...

Challenges of CRISPR/Cas9 applications for long non-coding RNA genes

lncRNA

The CRISPR/Cas9 system provides a revolutionary genome editing tool for all areas of molecular biology. In long non-coding RNA (lncRNA) research, the Cas9 nuclease can delete lncRNA genes or introduce RNA-destabilizing elements into their locus. The nuclease-deficient dCas9 mutant retains its RNA-dependent DNA-binding activity and can modulate gene expression when fused to transcriptional repressor or activator domains. Here, researchers from ...

RNA promotes metastasis in lung cancer

Lungs

The vast majority – approximately 80 percent – of our DNA does not code for proteins, yet it gets transcribed into RNA. These RNA molecules are called non-coding and fulfill multiple tasks in the cell. Alongside a well-studied group of small RNAs, there is also a class of so-called long non-coding RNAs consisting of more than 200 nucleotides. Long non-coding ...
