MarkerDB

MarkerDB provides a consolidated database of molecular biomarkers (chemical, protein, DNA/genetic, and karyotypic) for diagnostic, predictive, prognostic, and exposure-related biomedical research.

Key Features:

• Biomarker Types and Categories: Four molecular biomarker types are represented—chemical, protein, DNA (genetic), and karyotypic—and entries are categorized as diagnostic, predictive, prognostic, or exposure markers.
• Comprehensive Data Coverage: Entries include names and synonyms, associated conditions/pathologies, detailed disease and biomarker descriptions, sensitivity, specificity, ROC curves, standard reference values for protein and chemical markers, variant data for genetic markers, sequence information for genetic and protein markers, molecular structures for protein and chemical markers, and tissue or biofluid sources.
• Genomic and Cytogenetic Details: Genetic and karyotype markers include chromosomal location and structural details.
• Clinical Relevance: Clinical approval status and literature references are provided for biomarkers.
• Search and Analysis Functions: Data can be accessed by condition, condition category, biomarker type, or biomarker category, and an advanced search supports sequence similarity searches.
• Current Content Statistics: The database contains 142 protein biomarkers, 1,089 chemical biomarkers, 154 karyotype biomarkers, and 26,374 genetic markers associated with 670 specific human conditions grouped into 27 condition categories.

Scientific Applications:

• Disease Detection and Monitoring: MarkerDB supports identification and monitoring of human conditions with 25,560 diagnostic biomarkers.
• Prognostic Assessment: The resource provides 102 prognostic biomarkers for predicting disease outcomes.
• Predictive Analysis: MarkerDB contains 6,746 predictive biomarkers or panels for anticipating disease progression and treatment responses.
• Exposure Assessment: The database includes 265 exposure biomarkers for environmental health and exposure studies.

Methodology:

MarkerDB aggregates biomarker information from multiple sources, categorizes biomarkers by clinical utility, and implements sequence similarity search functionality.
