Summary: Monoclonal antibody-based therapy has proven effective against various diseases, but the co-production of mispaired species can reduce its efficacy and increase production costs. This study used transcriptomics and proteomics analyses to identify signaling pathways associated with low and high mispairing clone signatures. The results showed that high mispairing clones exhibited activated endoplasmic reticulum stress, while low mispairing clones had profiles indicative of activated protein translation. Additionally, a group of genes was identified as potential biomarkers for early detection of high mispairing levels.

Summary: Proteomics is undergoing a transformation with the use of deep learning methods to predict peptide fragmentation spectra. These methods have superseded traditional approaches and shown improved sensitivity and specificity in peptide identification. Machine learning has significant applications in immunopeptidomics and proteogenomics, although challenges remain in predicting spectra for modified peptides and cross-linked peptide pairs.

The study found an increase in transcriptional heterogeneity during infection, which was linked to the expression of baculovirus genes and rAAV2 transgenes. Additionally, the study highlighted limitations of the dual-baculovirus system in producing rAAV2 particles.

Summary: Cellular senescence refers to a stable cell cycle arrest state with specific characteristics. Senescent cells accumulate in the body during normal aging, limiting lifespan and promoting aging-related as well as unrelated diseases. Diseases associated with cellular senescence are referred to as senopathies, and targeting senescent cells through senolytics or senomorphics may help mitigate these diseases. Animal studies provide mechanistic evidence for the connection between senescent cell accumulation and disease progression in various senopathies, including cardiovascular, metabolic, musculoskeletal, liver, kidney, lung diseases, and neurodegeneration. The development of novel senotherapies is hindered by the heterogeneity of senescence phenotypes, resulting in a lack of universal biomarkers and difficulties in distinguishing senescent from non-senescent cells.

Summary: This case-control study aimed to investigate potential differences in circulating miRNAs between young individuals with long-duration type 1 diabetes (T1D) and healthy controls, as well as the expression of these identified miRNAs across different tissues. The results showed that 27 miRNAs were upregulated and one was downregulated in T1D. Six of these miRNAs were tissue-enriched. These findings have important implications for studying biomarkers for diabetes-related complications.

Summary: European mistletoe is a hemiparasitic flowering plant with an extremely large genome size. A transcriptome project was conducted to study its gene space, resulting in a database containing sequences of thousands of open reading frames encoding distinct proteins. A new database, VaGs II, was developed by combining data from a summer and winter transcriptome project, and it showed a higher completeness compared to the previous database. The quality of the new database was evaluated by re-analyzing proteome data, which provided new insights into the oxidative phosphorylation system of European mistletoe.

Summary: This study used metagenomic and metaproteomic analyses to investigate the microbial communities in a full-scale biogas plant with three differently operated digesters. The results showed that these microbial communities had a significant impact on the abundance of enzymes and genes involved in the biogas process, and identified key microorganisms involved in different steps of anaerobic digestion. Further analysis of the highly abundant MAGs in all digesters indicated their potential in ensuring biogas process stability.
