Abstrakt:	Functional RNA participates in various life processes in cells. However, there is currently a lack of effective methods to screen for functional RNA. Here, we developed a technology named random high-throughput screening (rHTS). rHTS uses a random library of ∼250-nt synthesized RNA fragments, with high uniformity and abundance. These fragments are circularized into circular RNA by an auto-cyclizing ribozyme to improve their stability. Using rHTS, we successfully screened and identified three RNA fragments contributing significantly to the growth of Escherichia coli, one of which possesses coding potential. Moreover, we found that two noncoding RNAs (ncRNAs) effectively inhibited the growth of E. coli, in vivo rather than in vitro. Subsequently, we applied the rHTS to a coenzyme-dependent screening platform. In this context, two ncRNAs were identified that could effectively promote the conversion from NADPH to NADP+. Exogenous expression of these two ncRNAs was able to increase the conversion rate of glycerol dehydrogenase from glycerol to 1,3-dihydroxyacetone from 18.3% to 21.8% and 23.2%, respectively. These results suggest that rHTS is a powerful technology for functional RNA mining. (© The Author(s) 2024. Published by Oxford University Press on behalf of Nucleic Acids Research.)
