Article Abstract

Amino acid residues are crucial to protein structure and function and have links to various human diseases. Here, we present a protocol for screening functional lysine residues across the human genome. We describe steps for designing lysine codon-targeting single-guide RNAs (sgRNAs), constructing an sgRNA library, conducting cell fitness screenings, and acquiring screening results. This approach leverages base editing and high-throughput screening techniques to systematically examine functional amino acid residues. For complete details on the use and execution of this protocol, please refer to Bao et al..

Parallel syntheses and their throughput capabilities are powerful tools for the rapid generation of molecule libraries, making them highly beneficial for accelerating hit identification in early-stage drug discovery. Utilizing chemical spaces and virtual libraries enhances time and cost efficiency, enabling the faster exploitation of chemically diverse compounds. In this study, a parallel synthesis method for rapidly generating a 5'-amino-5'-deoxy adenosine-based amide and sulfonamide library of 42 compounds is described with high yields and purity, which is economical and ecological due to the reduced requirements for extensive purification.

Former studies indicate that nuclear receptor subfamily 4 group A member 2 (Nurr1, NR4A2), a transcription factor, is regarded as a potential therapeutic target for central nervous system diseases, and many studies have focused on the development and optimization of agonists of Nurr1. Recent studies have shown that Nurr1 is upregulated in many other diseases. However, there is still a lack of effective inverse Nurr1 agonists as a therapeutic strategy or as pharmacological tools to counteract the receptor's inherent activity.

Single-cell analysis provides critical insights into cellular heterogeneity, dynamic behaviours and microenvironmental interactions, driving advancements in precision medicine and disease mechanism research. However, traditional technologies face limitations due to low throughput, insufficient sensitivity and bottlenecks in multi-omics integration. Microdroplet printing technology, with its advantages in high-throughput single-cell encapsulation, picolitre-level reaction precision and oil-free phase contamination avoidance, has propelled single-cell analysis into a new era of high-throughput and high-dimensional resolution through deep integration with multimodal detection platforms.

The global rise of mosquito-borne diseases and widespread resistance to existing insecticides highlight the urgent need for novel, field-relevant mosquitocides. Here, we report the development and validation of a high-throughput, in vivo screening assay capable of evaluating adult mosquito toxicity across large chemical libraries. Utilizing a 96-well plate format, this assay enables simultaneous testing of hundreds of compounds per run using both net and filter paper substrates, with direct measurement of adult mosquito knockdown and mortality via tarsal contact - an exposure route highly relevant to real-world vector control tools such as long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS).

Recombinant proteins have been widely applied in the food, biomedical, and scientific fields. Prokaryotic expression systems are preferred platforms for recombinant protein production due to their rapid growth and high protein yields. Nevertheless, disparities between recombinant expression environment and native physiological conditions frequently result in protein misfolding, leading to aggregation into non-functional inclusion bodies or proteolytic degradation.
