You might reasonably believe that the DNA in your cells is well protected in its cocoon of chromosomes, snuggly buried in the nuclei of your cells. Regrettably, such is not the case. DNA is a highly reactive biological compound that sustains various types of damage and alterations by ...

offering durability and long-lasting protection. If any part of the wrap gets damaged, it can be easily repaired or replaced without the need for a complete repaint. This not
After the scans, the research did show an increase in DNA damage in cells, as well as cell death. There was also increased expression of genes involved in the repair or death of cells, the study found. Most cells damaged by the CT scan were repaired, the researchers said, but a small...
in the whale's genes. Those changes are linked to cancer, aging and cell growth. The results suggest that the whales are better than humans at repairing their DN A. That's important because damaged or flawed DNA can lead to disease, including some cancers.Bowhead whales are also better a...
Downregulation of apoptosis induction appears to be the main mechanism of cancer cell resistance to platinum drugs. If DNA-damaged cells cannot undergo apoptosis, the upregulation of alternative cell death pathways may take place. In particular, the disruption of caspase cascade often results in the...
These cancer cells have the ability to produce or turn on production of the QRPT enzyme. This enzyme breaks down quinolinic acid into NAD+ which is vital for DNA repair of damaged cells. When more QRPT is produced, more NAD+ is made, and these cancer cells can thus repair themselves mo...
During meiotic prophase I, double-strand DNA breaks (DSBs) are induced across the genome.1 A subset of DSBs must be repaired as interhomolog crossovers to ensure accurate chromosome segregation, and the remaining DSBs are repaired through other mechanisms.3 While the homolog is the preferred recom...
In addition, the CCR7 ligand CCL21 was transiently expressed around damaged cartilage in juvenile mice, whereas it is rarely expressed in adults. Notably, exogenous CCL21 administration to adults decreased scar-forming healing and enhanced hyaline-cartilage repair in rabbit osteochondral defects. Our ...
