1. Radiation response in human cells : DNA damage formation, repair and signaling
Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

2. Replication Dynamics in the DNA Damage Response
Abstract : Faithful DNA replication is essential and the induction of replication stress may have profound effects on genomic integrity. This is demonstrated by the formation of DNA double strand breaks (DSBs), considered to be the most toxic DNA lesions, at stalled replication forks. READ MORE

3. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response
Abstract : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. READ MORE

4. Ribonucleotide reductase and DNA damage
Abstract : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. READ MORE

5. Primary Sjögren's Syndrome: Studies of DNA damage responses and autoantibodies
Abstract : Primary Sjögren’s syndrome (SS) is a chronic autoimmune disease of unknown etiology. The disease primarily involves lachrymal and salivary glands, leading to dryness of the eyes and mouth, but a wide spectrum of exocrine and non-exocrine disease manifestations may be seen. READ MORE
