AI Article Synopsis

  • Researchers are focusing on multiple gene silencing to effectively target metabolic pathways in eukaryotic organisms, necessitating the creation of refined RNA interference (RNAi) cassettes.
  • A new two-step cloning strategy was developed to create multisite small interfering RNA (siRNA) cassettes, which optimizes the arrangement of siRNA sites in target messenger RNAs (mRNAs) for efficiency.
  • This method utilizes one-step PCR with specially designed long primers, providing advantages in rapid screening, cost-effectiveness, and reduced procedural length, while also ensuring high stability and optimal structural validity of constructs in plants.

Article Abstract

Multiple gene silencing is being required to target and tangle metabolic pathways in eukaryotes and researchers have to develop a subtle method for construction of RNA interference (RNAi) cassettes. Although, several vectors have been developed due to different screening and cloning strategies but still some potential limitations remain to be dissolved. Here, we worked out a simple cloning strategy to develop multisite small interfering RNA (siRNA) cassette from different genes by two cloning steps. In this method, effective siRNA sites in the target messenger RNAs (mRNAs) were determined using analysis and consecutively arranged to reduce length of inverted repeats. Here, we used one-step (polymerase chain reaction) PCR by designed long primer sets covering the selected siRNA sites. Rapid screening, cost-effective and shorten procedure are advantages of this method compare to PCR classic cloning. Validity of constructs was confirmed by optimal centroid secondary structures with high stability in plants.

To analyze the distribution characteristics of work-related musculoskeletal disorders (WMSDs) among the occupational population in China's key industries during the period from 2018 to 2023, and to provide data support for the formulation of targeted prevention strategies. Between January 1, 2018, and December 31, 2023, a cross-sectional epidemiological survey and a retrospective investigation were conducted in seven geographical regions of North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China, using a combination of epidemiological cross-sectional and retrospective surveys. The industries were stratified according to the degree of closeness to WMSDs, the size of the occupational population, and the importance of the national economy, and then cluster sampling was conducted according to the size of the enterprises (large, medium, and small) within each stratum.

Using CO as the C1 source for N-formylation of amine is a crucial energy-storage pathway to address the greenhouse effect while generating high-value-added chemicals but is limited by the activation of inert molecules. Herein, a dual active site catalyst with high CO activation and dihydrogen dissociation capacity was fabricated by incorporating a Schiff base and Au nanoparticles (NPs) on silicon dioxide (SiO). The modification of the Schiff base not only provides an alkaline environment for CO absorption but also stabilizes Au NPs in a small and highly dispersed state, which regulates the electronic density of the metal for excellent H cleavage.

Multiple Topology Replica Exchange of Expanded Ensembles for Multidimensional Alchemical Calculations.

J Chem Theory Comput

Department of Chemical and Biological Engineering, University of Colorado Boulder, Boulder, Colorado 80309, United States.

Relative free energy (RFE) calculations are now widely used in academia and the industry, but their accuracy is often limited by poor sampling of the complexes' conformational ensemble. To help address conformational sampling problems when simulating many relative binding free energies, we developed a novel method termed multiple topology replica exchange of expanded ensembles (MT-REXEE). This method enables parallel expanded ensemble calculations, facilitating iterative RFE computations while allowing conformational exchange between parallel transformations.
