pubmed-article:15897703 | pubmed:abstractText | Apoptosis seems to play an important role in tumorigenesis, prognosis and therapy of testicular tumors. To understand its biological significance, it is important to quantify the amount of apoptosis and to compare the rate of apoptosis to that of a normal, unaffected reference tissue. Usually tissue from the unaffected site of the testis in patients with testicular cancer or testis tissue from patients who underwent surgical castration due to prostate cancer is used as the reference tissue. However it is not known, if both tissues are equivocal with respect to their apoptotic index. The purpose of the study was to compare the two most often used reference tissues for the quantification of apoptosis in testicular tissues with regard to their apoptotic index. | lld:pubmed |
