Welcome to AgingHallmarksDB

Aging is a complex biological process driven by the interplay of multiple genetic and molecular factors. Understanding the genetic basis of aging is essential for advancing research in health, longevity, and age-related diseases. The hallmarks framework, originally proposed by Carlos López-Otín and colleagues in 2013 and later updated in 2023, provides a widely accepted conceptual structure for systematically organizing the molecular and cellular alterations underlying aging hallmarks.

Here, we present AgingHallmarksDB, an interactive web platform that systematically catalogs and curates genes associated with the 11 of 12 hallmarks of aging through the integration of multiple established biological databases. In addition to hallmark-specific gene annotations, the platform provides tissue specificity, cell-type classifications, exosome-associated expression, transcription factor (TF)–target interactions, and kinase–substrate relationships, enabling a systems-level understanding of aging biology. AgingHallmarksDB further supports hallmark enrichment analysis of user-submitted gene lists and offers interactive network visualizations to explore the regulatory and signalling landscapes underlying aging-associated molecular processes across tissues and cellular systems.

Hallmark Enrichment

Identify significantly enriched aging hallmarks within the user-provided gene set.


1 Enter gene list

⚠️ Critical GSEA Requirement: You must input your entire, unfiltered transcriptome (all measured genes, typically 15,000+) ranked by their expression metric (e.g., fold-change). Submitting a small, pre-filtered list of only significant genes breaks the algorithm's statistical background model and yields invalid results.

Help & Tutorial


1. Browse

The Browse page offers a comprehensive overview of the 11 of 12 recognized hallmarks of aging. By clicking on any hallmark icon, users can dynamically generate a detailed table of its associated genes. These results can be further refined by applying stringent evidence-based filters or by restricting the search to specific tissues and cell-type classes.

2. Hallmark Enrichment

The Hallmark Enrichment module allows users to perform hallmark enrichment analysis using two distinct approaches: Standard Overlap (ORA) by submitting a simple list of Entrez Gene IDs, or Ranked GSEA by providing a list of genes with associated ranking metrics (such as log fold-change). Users can refine their analysis by selecting parameters such as gene set type, evidence stringency, and specific tissue or cell-type filters. After clicking “Run Analysis”, an interactive results dashboard is generated. This dashboard displays enriched hallmarks along with their statistical significance (adjusted p-values) and, for GSEA, Normalized Enrichment Scores (NES). These results can be further filtered based on user-defined minimum overlap and significance thresholds. Users can visualize ORA and GSEA results using highly customizable bar plots, bubble plots, or circular plots, while GSEA results further feature dedicated, hallmark-specific enrichment (barcode) plots. All generated plots can be downloaded directly in high-resolution PDF or PNG formats.

3. Gene Annotation

The Gene Annotation tool allows user to rapidly extract structured metadata for a customized list of Entrez Gene IDs. Upon submission, the platform redirects to a summary overview followed by an annotated table. This table maps the input genes to their respective aging hallmarks and details their spatial expression profile, including their documented presence across various tissues, specific cell types, and exosome datasets.

4. PPI Network Topology

The PPI Network Topology module provides protein-protein interaction-based topological analysis of hallmark-associated genes using degree, betweenness centrality, and closeness centrality to identify key network nodes.

5. Regulatory Interactions

The Regulatory Interactions module offers advanced topological mapping for user-defined gene sets, visualizing key biological interaction:

  • TF-Target Interactions: Maps internal transcriptional regulatory interaction specifically between the provided genes to identify key driver hubs.
  • Kinase-Substrate Interactions: Maps specific phosphorylation events and signaling cascades among the user input genes.
Both tools render dynamic, interactive graphs where users can select individual nodes to highlight specific interactions and local neighborhoods. For further analysis and reporting, these visualizations can be exported in high-quality HTML format, and the raw interaction data is summarized in an accompanying downloadable table.
