Clinical trials: DNA Strand Breaks
Breast Cancer
Study Evaluating DNA Double-strand Breaks (DSBs) REpair Factors (POLQ, Shieldin Complex and 53BP1) Expression as Biomarker of PARP Inhibitor Resistance in Patients With Deleterious Germline Mutation in BRCA 1/2 and HER2-negative, Metastatic or Locally Advanced Breast Cancer.
The purpose of this study is to assess whether expression of not only POLQ/Polθ, but also Shieldin complex and/or 53BP1 are correlated with primary and/or acquired resistance to PARPi (Poly(ADP-Ribose) Polymerases inhibitors) in…

Coronary Artery Disease
DNA Double-strand Breaks After SPECT
Ionizing radiation has a number of harmful effects in humans. The most important among these is the induction of cancer. It is assumed that damage to DNA in the nucleus of a single cell can induce cancer.

Male Infertility
Impact of Antioxidant Treatment on DNA Fragmentation Index
Increased sperm DNA Fragmentation Index implies decreased male fertility in vivo and in vitro. There is need for developing new strategies for improvement of male fertility.
