SUMMARY

The discussion centers on the breakdown of telomerase in the human body, highlighting its presence during early life and subsequent degradation. It is established that during mitosis, telomerase is equally distributed between daughter cells, resulting in a reduction of telomerase levels. In meiosis, a mechanism restores telomerase levels to ensure proper embryonic development. Additionally, the conversation touches on the implications of anti-aging drugs targeting telomerase, which may increase cancer risk.

PREREQUISITES
  • Understanding of telomere biology and function
  • Knowledge of mitosis and meiosis processes
  • Familiarity with genetic mechanisms in embryonic development
  • Awareness of the relationship between telomerase and cancer
NEXT STEPS
  • Research the mechanisms of telomerase degradation in human cells
  • Explore the role of telomerase in cancer biology
  • Investigate current anti-aging therapies targeting telomerase
  • Learn about the implications of telomere length on cellular aging
USEFUL FOR

Genetics students, researchers in cellular biology, medical professionals interested in aging and cancer, and anyone exploring the implications of telomerase in health and disease.

So I've finished my university's genetics class and we talked about how telomerase is present in a human early in life but then it disappears. Does anyone here how exactly the body breaks it down? Is there a specific chemical released throughout the body that causes it to degrade?

If I remember correctly, during mitosis the telomerase on each chromosome is split equally between the two daughter cells, so each one has only half as much as the original cell. During meiosis there is some mechanism that builds the telomerase back up so the fertilized embryo begins development with enough that it can keep dividing normally. A lot of research into anti-aging drugs has targeted telomerase, but I believe those drugs also increased the risk of cancer.
