Cytogenetic and molecular studies have suggested that deletion or rearrangement of sequences that map to the short arm of chromosome 8 may be permissive for tumorigenesis in several organ systems, and in human prostate tumors in particular. In this study, we hypothesized that genes deleted for one copy and localized to the 8p chromosomal region may be transcriptionally down-regulated or ablated...

Prostate cancer is a threat to men and usually occurs in aged males. Though prostate specific antigen level and Gleason score are utilized for evaluation of the prostate cancer in clinic, the biomarkers for this malignancy have not been widely recognized. Furthermore, the outcome varies across individuals receiving comparable treatment regimens and the underlying mechanism is still unclear. We ...

We have generated two new mouse monoclonal antibodies against prostate cancer. P25.48 (IgG3) and P25.91 (IgG2a) were derived from a fusion using fresh prostate cancer cells as the immunogen. Initial screening was performed by indirect immunofluorescence on frozen tissue sections of prostate cancer specimens. The specificity analysis was performed by indirect immunoperoxidase on frozen sections ...

Background: Certain marker studies have practical importance in the biology of prostate cancer. The purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas. Methods: The present study was performed on samples...

There are emerging data on novel tumor markers such as matrix metalloproteinase-2 (MMP-2 or gelatinase-A), which play a key role in tissue invasion and metastasis. We designed an investigation to assess the usefulness of MMP-2 activity as compared to prostate specific antigen (PSA) in cancer staging process. We have analyzed the circulating form of MMP-2 in serum samples of patients suffering f...

This study aimed to investigate the expression of A20 protein in prostate cancer tissues and its relationship with postoperative recurrence and survival. 86 patients with prostate cancer received surgery were collected as observation group, while 20 cases of benign prostatic hyperplasia were selected as control group in our hospital during June 2012 to June 2015. RT-PCR and immunohistochemistry...

A variety of tumor cells produce chemokines that promote tumor cell proliferation and chemotaxis. We previously reported that CXCL16 production is increased in aggressive prostate cancer cells compared with the less aggressive tumor cells and benign cells as identified in a cytokine antibody array. The functional contribution of CXCL16 in prostate cancer development has not yet been evaluated. ...
