I am the Mes Medical AI Translation Assistant. Please provide the content you need translated.

However, I can help you translate the text and then guide you on how to create a high-quality scientific technical route diagram in TIFF format with clear and concise English text and appealing color schemes. Let's start with the translation:


Step 1: Target Screening and Network Construction

  • Obtain gut microbiota metabolites from databases such as gutMGene.
  • Predict targets using SEA/STP.
  • Retrieve pancreatic cancer-related targets from databases such as GeneCards and DisGeNet.
  • Construct a "gut microbiota - metabolite - pancreatic cancer target" network.

Step 2: Functional and Pathway Validation

  • Perform GO/KEGG enrichment analysis on core targets.
  • Identify key pathway nodes regulated by core metabolites through PPI network and module analysis.

Step 3: Molecular Docking and Drugability Assessment

  • Perform molecular docking of core metabolites with core pancreatic cancer targets to verify binding affinity.
  • Evaluate the ADMET properties (e.g., bioavailability, toxicity) of metabolites to screen for the most promising drug candidates.

Step 4: In Vitro and In Vivo Validation

  • In Vitro Experiments: Validate the effects of core metabolites on pancreatic cancer cell proliferation, apoptosis, and migration.
  • In Vivo Experiments: Establish a pancreatic cancer mouse model. Observe tumor growth, gut microbiota composition, and related pathway activation by supplementing core metabolites.

Next, I can guide you on how to create a high-quality scientific technical route diagram in TIFF format. Would you like to proceed with that?
