Telomeres and Cancer   no comments

This is a topic you’ll see surface quite a bit on the Internet.  Today I’ll address just exactly what is the connection between telomeres and cancer.

When a cell starts to become a cancer (cancerous), it has the tendency to divide more frequently.  The telomeres, in turn, become very short.  When they become too short, they have the tendency to die.  Often, these cells make it by generating more of the telomerase enzyme, and this can prevent them from becoming shorter.

Cancers often are linked to shortened telomeres.  Most notably, bone, prostate, bladder, neck, head, pancreatic, and bladder forms.

Trying to detect cancer is as simple (although not scientifically agreed upon yet) as measuring telomerase.  If professionals can learn to stop telomerase, they may just have the ability to fight cancer by forcing cancer cells age and die.

One noteworthy experiment showed that in a laboratory, researchers blocked telomerase activity in human breast and prostate cancer cells and in turn, made them die.  However, there is risk involved, as this can impair fertility, healing of wounds, and also hurt the ability to produce blood cells and immune system cells.
