Telomeric DNA damage is irreparable and causes persistent DNA-damage-response activation

DNA damage response inhibition at dysfunctional telomeres by modulation of telomeric DNA damage response RNAs

The DNA damage response (DDR) is a set of cellular events that follows the generation of DNA damage. Recently, site-specific small non-coding RNAs, also termed DNA damage response RNAs (DDRNAs), have been shown to play a role in DDR signalling and DNA repair. Dysfunctional telomeres activate DDR in ageing, cancer and an increasing number of identified pathological conditions. Here we show that,...

DNA Damage Response Pathways

ownload B4 is unusual among receptor tyrosine kinases because some isoforms can be efficiently cleaved at the a membrane to release a soluble intracellular domain. The cleavage product has high kinase activity mes to the nucleus. A screen for proteins that associate with the ErbB4 intracellular domain identified ate interactors including ITCH, WWP2, Nucleolin, and Krab-associated protein 1 (Kap...

DNA damage response and neuroprotection.

The protection of genomic integrity is a major challenge for living cells that are continuously exposed to endogenous and environmental DNA-damaging insults. To cope with the consequences of DNA lesions which interfere with essential DNA-dependent processes including transcription and replication, cells are equipped with an efficient defense mechanism termed the DNA damage response. Its functio...
