Patchouli alcohol (PA) is a widely used pharmaceutical ingredient in various Chinese traditional herbal medicine (THM) formulations, known for its modulatory effects on the gut microbiota. The present study investigated PA's anti-inflammatory and regulatory effects on gut microbiota and its mode of action (MOA). Based on the assessments of ulcerative colitis (UC) symptoms, PA exhibited promising preventions against inflammatory response. In accordance, the expressions of pro-inflammatory factors, including interleukin (IL)-1β, IL-6, tumor necrosis factor-α, and chemokine ligand 5 were significantly attenuated under PA treatment. Furthermore, PA enhanced the intestinal barrier damage caused by dextran sodium sulfate (DSS). Interestingly, PA exhibited negligible inventions on DSS-induced gut microbiota dysbiosis. PA did not affect the diversity of the DSS gut microbiota, it did alter the composition, as evidenced by a significant increase in the Firmicutes-Bacteroidetes (F/B) ratio. Finally, the MOA of PA against inflammation in DSS-treated mice was addressed by suppressing the expressions of heme oxygenase-1 (HO-1) and inducible nitric oxide synthase (iNOS). In conclusion, PA prevented inflammatory response in the DSS-induced UC mice model via directly suppressing HO-1 and iNOS-associated antioxidant signal pathways, independent of its effects on gut microbiota composition.

NIH genetic sequence database that provides annotated collection of all publicly available DNA sequences for almost 280 000 formally described species (Jan 2014) .These sequences are obtained primarily through submissions from individual laboratories and batch submissions from large-scale sequencing projects, including whole-genome shotgun (WGS) and environmental sampling projects. Most submissions are made using web-based BankIt or standalone Sequin programs, and GenBank staff assigns accession numbers upon data receipt. It is part of International Nucleotide Sequence Database Collaboration and daily data exchange with European Nucleotide Archive (ENA) and DNA Data Bank of Japan (DDBJ) ensures worldwide coverage. GenBank is accessible through NCBI Entrez retrieval system, which integrates data from major DNA and protein sequence databases along with taxonomy, genome, mapping, protein structure and domain information, and biomedical journal literature via PubMed. BLAST provides sequence similarity searches of GenBank and other sequence databases. Complete bimonthly releases and daily updates of GenBank database are available by FTP.
View all literature mentionsDatabase of biological data related to a single initiative, originating from a single organization or from a consortium. A BioProject record provides users a single place to find links to the diverse data types generated for that project. It is a searchable collection of complete and incomplete (in-progress) large-scale sequencing, assembly, annotation, and mapping projects for cellular organisms. Submissions are supported by a web-based Submission Portal. The database facilitates organization and classification of project data submitted to NCBI, EBI and DDBJ databases that captures descriptive information about research projects that result in high volume submissions to archival databases, ties together related data across multiple archives and serves as a central portal by which to inform users of data availability. BioProject records link to corresponding data stored in archival repositories. The BioProject resource is a redesigned, expanded, replacement of the NCBI Genome Project resource. The redesign adds tracking of several data elements including more precise information about a project''''s scope, material, and objectives. Genome Project identifiers are retained in the BioProject as the ID value for a record, and an Accession number has been added. Database content is exchanged with other members of the International Nucleotide Sequence Database Collaboration (INSDC). BioProject is accessible via FTP.
