Hyperglycemia Differentially Affects Maternal and Fetal DNA Integrity and DNA Damage Response

Hyperglycemia Differentially Affects Maternal and Fetal DNA Integrity and DNA Damage Response.

OBJECTIVE Investigate the DNA damage and its cellular response in blood samples from both mother and the umbilical cord of pregnancies complicated by hyperglycemia. METHODS A total of 144 subjects were divided into 4 groups: normoglycemia (ND; 46 cases), mild gestational hyperglycemia (MGH; 30 cases), gestational diabetes mellitus (GDM; 45 cases) and type-2 diabetes mellitus (DM2; 23 cases). ...

Analysis of chromatin integrity and DNA damage of buffalo spermatozoa

This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...

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...
