Women's Breast Tissue Ages Faster Than Rest of Body
Everyone grows older, but scientists
don't really understand why. Now a UCLA study has uncovered a biological clock
embedded in our genomes that may shed light on why our bodies age and how we
can slow the process. Published in the Oct. 21 edition of Genome
Biology, the findings could offer valuable insights into cancer and stem
cell research.
While earlier clocks have been linked
to saliva, hormones and telomeres, the new research is the first to identify an
internal timepiece able to accurately gauge the age of diverse human organs,
tissues and cell types. Unexpectedly, the clock also found that some parts of
the anatomy, like a woman's breast tissue, age faster than the rest of the
body.
