CellAge Database of Cell Senescence Genes

Cell senescence can be defined as the irreversible cessation of cell division of normally proliferating cells. Human cells become senescent from progressive shortening of telomeres as cells divide, stress or oncogenes. Primarily an anti-tumour mechanism, senescent cells accumulate with age in tissues and have been associated with degeneration and ageing of whole organisms. Many proteins have been linked to cell senescence as biomarkers and as causal drivers. To facilitate studies focused on cell senescence, we developed CellAge, a database of genes associated with cell senescence. Our manually-curated data is based on gene manipulation experiments in different human cell types. A gene expression signature of cellular senescence is also available. By integrating these and other datasets we performed a systems biology analysis of cell senescence.

Finding Entries in CellAge

Searching and browsing the full dataset is simple and intuitive. Just type your search query to filter the data, such as by using a gene name or HGNC symbol, or perhaps the name of a cell type. Note that the search is case insensitive.

Search gene manipulations

Genes associated with cellular senescence based on genetic manipulation experiments. Enter a single gene or comma separated list, or leave blank to retrieve all genes:

Search molecular signatures

Genes that are either over-expressed or under-expressed during replicative senescence of human cells.

A summary of the database, such as genes and cell lines available, is made available via the CellAge statistics page.

Downloading CellAge

You can download all genes associated with cell senescence as a CSV file. You can also download the gene expression signatures as a CSV file.
