High-Throughput-Methyl-Reading (HTMR) assay: A solution based on nucleotide methyl-binding proteins enables large-scale screening for DNA/RNA methyltransferases and demethylases

Epigenetic therapy has significant potential for cancer treatment. However, few small potent molecules have been identified against DNA or RNA modification regulatory proteins. Current approaches for activity detection of DNA/RNA methyltransferases and demethylases are time-consuming and labor-intensive, making it difficult to subject them to high-throughput screening. Here, we developed a fluorescence polarization-based "High-Throughput Methyl Reading" (HTMR) assay to implement large-scale compound screening for DNA/RNA methyltransferases and demethylases-DNMTs, TETs, ALKBH5, and METTL3/METTL14. This assay is simple to perform in a mix-and-read manner by adding the methyl-binding proteins MBD1 or YTHDF1. The proteins can be used to distinguish FAM-labelled substrates or product oligonucleotides with different methylation statuses catalyzed by enzymes. Therefore, the extent of the enzymatic reactions can be coupled with the variation of FP binding signals. Furthermore, this assay can be effectively used to conduct a cofactor competition study. Based on the assay, we identified two natural products as candidate compounds for DNMT1 and ALKBH5. In summary, this study outlines a powerful homogeneous approach for high-throughput screening and evaluating enzymatic activity for DNA/RNA methyltransferases and demethylases that is cheap, easy, quick, and highly sensitive.

Interplay between Li and Na amid co-doped solution-processed Cu2ZnSn(S,Se)4 absorbers for solar cells

Alkali doping and alloying are well-known strategies to improve the performance of Cu2ZnSn(S,Se)4 (CZTSSe) absorber based thin film solar cells. The effects of individual light alkali elements such as Li and Na have been thoroughly investigated, with both dopants resulting in significant improvements in performance of CZTSSe solar cells. Here, the combined effects of Li and Na are investigated in a so-called co-doping approach to capture the benefits from both elements simultaneously. In order to do that, various concentrations of Li and Na between 0.0 M and 0.5 M are added to the solution used for spin coating of the precursor layer. After annealing under Se-enriched atmosphere, the two alkali elements displayed mutual dependency of in terms of their concentrations in the CZTSSe absorber layer. Furthermore, both, Li and Na showed signs of forming alloys with the CZTSSe phase. The efficiencies of the best Li-Na co-doped solar cells are above 10%, slightly above the Li baseline thanks to increased open-circuit-voltage and short-circuit current. A non-negligible Na incorporation was observed even in nominally Na-free devices, likely from indirect contamination from the SLG substrate. Further work is needed to better understand Na-poor compositions and draw conclusions relevant to Na-free substrates.

Data for publication "Surface tension models for binary aqueous solutions: A review and intercomparison"

This repository contains the data of the publication: Title: "Surface tension models for binary aqueous solutions: A review and intercomparison" Authors: Judith Kleinheins, Nadia Shardt, Manuella el Haber, Corinne Ferronato, Barbara Nozière, Thomas Peter, and Claudia Marcolli Date: 2023 Abstract: The liquid–air surface tension of aqueous solutions is a fundamental quantity in multi-phase thermodynamics and fluid dynamics and thus relevant in many scientific and engineering fields. Various models have been proposed for its quantitative description. This Perspective gives an overview of the most popular models and their ability to reproduce experimental data. In addition, we propose a new model based on the logistic function which reproduces sigmoidal curve shapes (Sigmoid model) to empirically fit experimental surface tension data. All models were tested on ten binary aqueous solutions of electrolytes and organic molecules. The surface tension of weakly surface active substances is well reproduced by all models. In contrast, only a few models successfully modelled the surface tension of aqueous solutions with strongly surface-active substances. For substances with a solubility limit, usually no experimental data is available for the surface tension of supersaturated solutions and the pure liquid solute. We discuss ways in which these can be estimated and emphasize the need for further research. The newly developed Sigmoid model best reproduces the surface tension of all tested solutions and can be recommended as a model for a broad range of substances and over the entire concentration range.

Data from: More future synergies and less trade‐offs between forest ecosystem services with natural climate solutions instead of bioeconomy solutions

To reach the Paris Agreement, societies need to increase the global terrestrial carbon sink. There are many climate change mitigation solutions (CCMS) for forests, including increasing bioenergy, bioeconomy and protection. Bioenergy and bioeconomy solutions use climate-smart, intensive management to generate high quantities of bioenergy and bioproducts. Protection of (semi-)natural forests is a major component of 'natural climate solution' (NCS) since forests store carbon in standing biomass and soil. Furthermore, protected forests provide more habitat for biodiversity and non-wood ecosystem services (ES). We investigated the impacts of different CCMS and climate scenarios, jointly or in isolation, on future wood ES, non-wood ES, and regulating ES for a major wood provider for the international market. Specifically, we projected future ES given by three CCMS scenarios for Sweden 2020-2100. In the long term, fulfilling the increasing wood demand through bioenergy and bioeconomy solutions will decrease ES multifunctionality, but the increased stand age and wood stocks induced by rising greenhouse gas (GHG) concentrations will partially offset these negative effects. Adopting bioenergy and bioeconomy solutions will have a greater negative impact on ES supply than adopting NCS. Bioenergy or bioeconomy solutions, as well as increasing GHG emissions, will reduce synergies and increase trade-offs in ES. NCS, by contrast, increases the supply of multiple ES in synergy, even transforming current ES trade-offs into future synergies. Moreover, NCS can be considered an adaptation measure to offset negative climate change effects on the future supplies of non-wood ES. In boreal countries around the world, forestry strategies that integrate NCS more deeply are crucial to ensure a synergistic supply of multiple ES.
