Prostate cancer is the most frequently diagnosed cancer in males in the United States, accounting for an estimated 186,320 new cases in 2008. There are striking racial or ethnic differences in prostate cancer incidence and mortality rates in the United States, with Black males 1.6 times more likely to be diagnosed and 2.4 times more likely to die with prostate cancer than Whites. The stage at diagnosis is a key prognostic factor for prostate cancer survival, with African-Americans generally diagnosed at a more advanced stage. To identify factors that explain the race-stage disparity in prostate cancer, we conducted a population-based …
Nucleoplasmic And Cytoplasmic Degradation Of Telomerase: Implications Toward Telomerase-Based Cancer Therapy, Binh Nguyen
Nucleoplasmic And Cytoplasmic Degradation Of Telomerase: Implications Toward Telomerase-Based Cancer Therapy, Binh Nguyen
Theses and Dissertations
Telomerase is a ribonucleoprotein that is reactivated in cancer cells to allow for continuous cellular division and indefinite growth. With telomerase being expressed in more than 85% of all cancer, it is imperative that we understand how to selectively inactivate and degrade this unique DNA polymerase. In doing so, we can specifically target tumor cells to erode their telomeres so that they will undergo apoptosis or senescence. Through this research, we have learned that telomerase can be degraded in the nucleoplasm by Hsp90 chaperone inhibition and in the cytoplasm by the dominant negative mutant, D712A V713I. These findings should guide …

Aim: Prostatic adenocarcinoma shows remarkable variability in the incidence and biological behavior between populations from different races and geographical regions of the world. PTEN has been reported as the most commonly mutated tumor suppressor gene in prostate cancer. Incidence of PTEN alterations occurring in prostatic carcinoma has not been studied previously in the Turkish population. Materials and Methods: We examined PTEN protein expression immunohistochemically and its significance in 69 primary prostate cancer patients from Turkey. Two tissue microarrays constructed by 0.6 mm cores from radical prostatectomy specimens were used. Clinical information for all patients was obtained from hospital records. Results: …
