Article Abstract
The production of recombinant proteins at high levels often induces stress-related phenotypes by protein misfolding or aggregation. These are similar to those of the yeast Alzheimer's disease (AD) model in which amyloid-β peptides (Aβ42) were accumulated [1], [2]. We have previously identified suppressors of Aβ42 cytotoxicity via the genome-wide synthetic genetic array (SGA) [3] and here we use them as metabolic engineering targets to evaluate their potentiality on recombinant protein production in yeast . In order to investigate the mechanisms linking the genetic modifications to the improved recombinant protein production, we perform systems biology approaches (transcriptomics and proteomics) on the resulting strain and intermediate strains. The RNAseq data are preprocessed by the nf-core/RNAseq pipeline and analyzed using the Platform for Integrative Analysis of Omics (PIANO) package [4]. The quantitative proteome is analyzed on an Orbitrap Fusion Lumos mass spectrometer interfaced with an Easy-nLC1200 liquid chromatography (LC) system. LC-MS data files are processed by Proteome Discoverer version 2.4 with Mascot 2.5.1 as a database search engine. The original data presented in this work can be found in the research paper titled "Suppressors of Amyloid-β Toxicity Improve Recombinant Protein Production in yeast by Reducing Oxidative Stress and Tuning Cellular Metabolism", by Chen et al. [5].

The chimpanzee adenovirus-vectored vaccine developed by the University of Oxford (ChAdOx1 nCoV-19) showed good stability when stored in refrigerator. However, the vaccine manufacturer prefers its transportation in frozen condition. Data regarding the stability of the vaccine after exposure to repeated freezing processes have not been explored yet.

The breach of six planetary boundaries highlights the need for sustainable food production. Aerobic hydrogen-oxidising bacteria (HOBs) convert atmospheric CO and green hydrogen (H) into biomass via gas fermentation, a process already used for food-grade single-cell protein production. This approach enables a supply chain independent of agriculture, requiring minimal land and water, with potential for carbon-neutral production and carbon capture.

Chronic restraint stress (CRS) is a widely recognized model to study stress-induced anorexia and metabolic dysregulation in mice. Acyl-coenzyme A-binding protein (ACBP) has emerged as a critical player in metabolic regulation, with potential implications for stress-related disorders. This study presents two complementary methodologies to artificially elevate circulating Acyl-CoA-binding protein (ACBP) levels in mice under CRS.

Objective: Therapeutic potential of selective aggrecanase inhibition in osteoarthritis (OA) was previously demonstrated using a variant of endogenous tissue inhibitor of metalloproteinase-3 (TIMP-3); however, this relied on transgenic mice overexpressing TIMP-3. Here, we develop a translational approach for harnessing the aggrecanase-selective inhibitory activity of TIMP-3 using the latency associated peptide (LAP) technology.
Methods: We successfully produced and purified recombinant LAP-TIMP-3 fusion proteins and determined the pharmacokinetics of these proteins in vivo following systemic injection.

In modern drug discovery, there is a pressing need for rapid, cost-effective, and accessible methods to evaluate the biological activities of newly synthesized compounds. Traditional kinase assay platforms are often labor-intensive, time-consuming, and require specialized equipment or expertise. To address these limitations, we developed and validated a convenient in vitro kinase assay based on a recombinant biosensor, Picchu-B, constructed using a bacterial expression system.
