DNA Damage Responses in Aging (SAW 2014)

In funding line 3 (Networking) the Leibniz Association grants the FLI’s research project „DNA Damage Responses in Aging“.

DNA Damage Response

Accumulation of DNA damage, as observed in aged human tissues, is one of the molecular causes of aging. Cells respond to DNA damage by activating checkpoints that prevent the contribution of damaged cells to tissue homeostasis by induction of cell death (apoptosis), cell cycle arrest (senescence) or self-digestion of the damaged cells (autophagy). Induction of a DNA damage response (DDR) prevents cancer formation by eliminating genetically instable cells. However, when a growing number of cells in aging tissues accumulates DNA damage, the induction of the same responses can also lead to loss of tissue maintenance and tissue atrophy.

Approach

The main aims of our current proposal are to delineate the functional influence of the DDR on cellular and tissue aging at different levels and will be studied within a network of collaborating Leibniz Institutes (FMP, IUF, LIN). We hypothesize that specific inhibitors of central players of DDR can be developed for future therapies to promote healthy aging.
