Most Internet online resources for investigating HIV biology contain either bioinformatics tools, protein information or sequence data. The objective of this study was to develop a comprehensive online proteomics resource that integrates bioinformatics with the latest information on HIV-1 protein structure, gene expression, post-transcriptional/post-translational modification, functional activity, and protein-macromolecule interactions. The BioAfrica HIV-1 Proteomics Resource http://bioafrica.mrc.ac.za/proteomics/index.html is a website that contains detailed information about the HIV-1 proteome and protease cleavage sites, as well as data-mining tools that can be used to manipulate and query protein sequence data, a BLAST tool for initiating structural analyses of HIV-1 proteins, and a proteomics tools directory. The Proteome section contains extensive data on each of 19 HIV-1 proteins, including their functional properties, a sample analysis of HIV-1HXB2, structural models and links to other online resources. The HIV-1 Protease Cleavage Sites section provides information on the position, subtype variation and genetic evolution of Gag, Gag-Pol and Nef cleavage sites. The HIV-1 Protein Data-mining Tool includes a set of 27 group M (subtypes A through K) reference sequences that can be used to assess the influence of genetic variation on immunological and functional domains of the protein. The BLAST Structure Tool identifies proteins with similar, experimentally determined topologies, and the Tools Directory provides a categorized list of websites and relevant software programs. This combined database and software repository is designed to facilitate the capture, retrieval and analysis of HIV-1 protein data, and to convert it into clinically useful information relating to the pathogenesis, transmission and therapeutic response of different HIV-1 variants. The HIV-1 Proteomics Resource is readily accessible through the BioAfrica website at: http://bioafrica.mrc.ac.za/proteomics/index.html.

Clostridium thermocellum is an increasingly well-studied organism with considerable advantages for consolidated bioprocessing towards ethanol production. Here, a genome-scale resource balance analysis (RBA) model of C. thermocellum, ctRBA, is reconstructed based on a recently published stoichiometric model (iCTH669), global proteomics, and C MFA datasets to analyze proteome allocation and the burden imposed on metabolism with regard to ethanol yield and titer.

Background: The proteome is a valuable resource for pinpointing therapeutic targets. Therefore, we conducted a proteome-wide Mendelian randomization (MR) study aimed at identifying potential protein markers and therapeutic targets for Anti-N-Methyl-D-Aspartate Receptor Encephalitis (NMDAR-E).
Methods: Protein quantitative trait loci (pQTLs) were obtained from seven published genome-wide association studies (GWASs) focusing on the plasma proteome, resulting in summary-level data for 734 circulating protein markers.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

The etiology of alcoholic fatty liver (AFL) is complex, representing the early reversible stage of alcohol-associated liver disease (ALD). Alleviating oxidative stress, reducing inflammation, and preventing the development of liver fibrosis are considered the most effective strategies for treating AFL. Consequently, we selected isoliquiritigenin (ISL), a flavonoid compound recognized for its anti-inflammatory, antioxidant, and anticancer pharmacological properties.

The ectoparasitic honeybee (Apis mellifera) mite Tropilaelaps mercedesae represents a serious threat to Asian apiculture and a growing concern for global beekeeping due to its high reproductive capacity and host adaptability. However, the regulatory mechanisms underlying its host adaptation across life stages remain poorly characterized. Here, we performed integrated transcriptomic, proteomic, and metabolomic analyses of female mites at 4 key postembryonic developmental stages: protonymphs, deutonymphs, mature adults, and reproductive adults.
