Prostatic-Specific Antigen (PSA) is a low-molecular weight glycoprotein, that is uniquely associated with prostatic tissue. It has considerable diagnostic specificity for prostatic disease. Concentrations of PSA in serum correlate well with the stage of disease, and response to treatment in patients with prostatic cancer. It is, therefore, a good tumor marker for prostatic cancer. However, it h...
The prognostic value of the HNK-1 (Leu-7) antigen in prostatic cancer--an immunohistochemical study.
The anti-HNK-1 (Leu-7) monoclonal antibody (MAb) was revealed to be reactive with noncancerous and cancerous prostatic epithelial cells, although this antibody was originally found to be reactive against natural killer cells. However, the prognostic significance of HNK-1 antigen in prostatic cancer patients remains unknown. The expression of HNK-1 antigen on prostatic cancer was investigated im...
In previous allelotype analyses of human prostatic cancer specimens, allelic loss on the short arm of chromosome 8 is frequently observed. However, it is still unclear whether this allelic loss is an initial event or a later one in development of prostatic cancer. Our previous studies demonstrate that introduction of human chromosome 11 into highly metastatic rat prostatic cancer cells results ...
Previous studies have suggested that increased body mass is associated with an increased risk of prostatic cancer, but these studies have been limited by the fact that they were based on a few simple measurements such as height and weight. Similar results were found in a prospective study of the incidence of prostatic cancer in a cohort of Japanese men born in 1900-19 and living in Hawaii. Furt...
Introduction: Prostatic adenocarcinoma is the most common malignancy of internal system and after lung cancer is the second cause of death in male. Genetic base of many neoplasms is related to suppressor tumor gene such as P53. Therefore, we aimed in this study, to assess the intensity of prostatic adenocarcinoma tissue staining with P53 staining method and its relationship with Gleason grade. ...
Background and Aims: Prostate cancer (PCa) is one of the most common cancers among men in Iran. Since changes in the regulation of proto-oncogenes expression are the main causes of most human cancers, including PCa, evaluating the expression of marker genes can be helpful for early diagnosis of cancer and better understanding of its etiology. The present study compared c-Myc expression level in...
PURPOSE The organic anion transporter OATP1B3, encoded by SLCO1B3, is involved in the transport of steroid hormones. However, its role in testosterone uptake and clinical outcome of prostatic cancer is unknown. This study examined (a) the SLCO1B3 genotype in cancer cells as well as the uptake of testosterone by cells transfected with genetic variants of SLCO1B3; (b) the expression of OATP1B3 in...
Despite being the second most common cancer in males, and one from which mortality is increasing, cancer of the prostate remains in many ways an enigma. For example, little is known of its pathogenesis, although the androgenic hormones are clearly important, the incidence increases with age, and genetic factors also have a role. Furthermore, while its development appears to involve a progressio...
Hypermethylation of regulatory sequences at the locus of the pi-class glutathione S-transferase gene GSTP1 was detected in 20 of 20 human prostatic carcinoma tissue specimens studied but not in normal tissues or prostatic tissues exhibiting benign hyperplasia. In addition, a striking decrease in GSTP1 expression was found to accompany human prostatic carcinogenesis. Immunohistochemical staining...
