Short telomeres linked with breast cancer

Ed Park, MD Uncategorized 0 Comments

A recent study suggests that critically-short telomeres may allow harmful changes. This study is like a ‘smoking gun’ in the understanding of cancer. Compared with similar but unaffected people, women who had developed breast cancer showed more worn-out telomeres. Since telomeres protect the tips of chromosomes, longer is better.

We’ve known for a long time that when the end of Chromosome 9 gets too short and crosses over to the end of Chromosome 22, you get a Philadelphia Chromosome and a kind of leukemia. When the telomeres shorten, this sort of crossing over is more likely to occur.

All it takes is one single end of one single chromosome in one single stem cell to produce a lethal process known as cancer.

Let’s keep those telomeres long with TA-65!

BACKGROUND: Telomere dysfunction is involved in the development of breast cancer and very short telomeres are frequent genetic alterations in breast tumors. However, the influence of telomere lengths of specific chromosomal arms on the breast cancer risk is unknown. METHODS: We conducted a case-control study of breast cancer to examine the associations of the telomere length on chromosome 9 short arms (9p) and long arms (9q) with risk of breast cancer. Chromosome 9 arm specific telomere lengths were measured by quantitative fluorescent in situ hybridization (FISH) using cultured blood lymphocytes. RESULTS: Telomere length on chromosome 9p was significantly shorter in breast cancer patients than in control subjects (P < 0.001). Using the 50th percentile value in controls as a cut point, women who have short 9p telomeres had an increased risk of breast cancer (adjusted odds ratio [OR] = 2.6; 95% confidence interval [CI], 1.5 - 4.3). When the 9p telomere length was divided into quartiles, a significant inverse dose-response relationship between 9p telomere length and breast cancer risk was observed (Ptrend < 0.001), with a quartile ORs of 3.0 (95% CI, 1.2-7.5), 3.9 (95% CI, 1.6-9.5), and 6.6 (95% CI, 2.8-15.9) for third, second and first quartile respectively when compared with women in the forth quartile. CONCLUSIONS: Short telomere length on chromosome 9p is strongly associated with the risk of breast cancer. If confirmed by future studies, chromosome 9p telomere length has the potential to be incorporated into the current prediction models to significantly enhance breast cancer risk prediction."

In 2007, I became the nineteenth patient to sign up for the use of a herbally-extracted telomerase activator.

The results were so positive that I founded Recharge Biomedical Clinic in 2008 and have since become the leading medical expert in this exciting new field of regenerative medicine treating over 1,300 patients with this exciting new telomerase activation medicine.

I won two Houston Film Festival Awards for my screenplays about Hypatia of Alexandria and Ed Brown of Kentucky.
