Split intron-exon system for circular RNA synthesis [PDF]

open access: yesNature Communications
Ribozyme-based approaches have been extensively employed for in vitro circular RNA (circRNA) synthesis. However, several critical challenges are impeding the progress in this field, including the relatively low ribozyme utilization efficiency, limited ...

Exonuclease Ribozyme Encoded in a Circular Genome: On the Initiation of the RNA World [PDF]

open access: yesLife
The “RNA World” hypothesis posits a reasonable scenario for the origin of life. A question central to this scenario is: which RNA species may have emerged as the first ribozyme, thereby initiating the earliest stage of life?

Structural Expansion of Catalytic RNA Nanostructures through Oligomerization of a Cyclic Trimer of Engineered Ribozymes

open access: yesMolecules, 2023
The multimolecular assembly of three-dimensionally structured proteins forms their quaternary structures, some of which have high geometric symmetry. The size and complexity of protein quaternary structures often increase in a hierarchical manner, with ...

RNase P Ribozyme Effectively Inhibits Human CC-Chemokine Receptor 5 Expression and Human Immunodeficiency Virus 1 Infection

open access: yesZoonotic Diseases, 2023
Developing novel antiviral agents and approaches is essential for the treatment against human and zoonotic viruses. We had previously produced RNase P-based ribozyme variants capable of efficiently cleaving mRNA in vitro.

A convolutional neural network for the prediction and forward design of ribozyme-based gene-control elements

open access: yeseLife, 2021
Ribozyme switches are a class of RNA-encoded genetic switch that support conditional regulation of gene expression across diverse organisms. An improved elucidation of the relationships between sequence, structure, and activity can improve our capacity ...

Effective inhibition of human immunodeficiency virus 1 replication by engineered RNase P ribozyme. [PDF]

open access: yesPLoS ONE, 2012
Using an in vitro selection procedure, we have previously isolated RNase P ribozyme variants that efficiently cleave an mRNA sequence in vitro. In this study, a variant was used to target the HIV RNA sequence in the tat region.

Catalytic RNA Oligomers Formed by Co-Oligomerization of a Pair of Bimolecular RNase P Ribozymes

open access: yesMolecules, 2022
Naturally occurring ribozymes with a modular architecture are promising platforms for construction of RNA nanostructures because modular redesign enables their oligomerization.

A cell-based ribozyme reporter system employing a chromosomally-integrated 5′ exonuclease gene

open access: yesBMC Molecular and Cell Biology, 2021
Background Bioinformatic genome surveys indicate that self-cleaving ribonucleic acids (ribozymes) appear to be widespread among all domains of life, although the functions of only a small number have been validated by biochemical methods.

Targeted suicide gene therapy for liver cancer based on ribozyme-mediated RNA replacement through post-transcriptional regulation

open access: yesMolecular Therapy: Nucleic Acids, 2021
Hepatocellular carcinoma (HCC) has high fatality rate and limited therapeutic options. Here, we propose a new anti-HCC approach with high cancer-selectivity and efficient anticancer effects, based on adenovirus-mediated Tetrahymena group I trans-splicing
