Characterization of SPINK1 in Prostate Cancer

Characterization of SPINK1 in Prostate Cancer PRINCIPAL INVESTIGATOR:

SPINK1 protein expression and prostate cancer progression.

PURPOSE SPINK1 overexpression has been described in prostate cancer and is linked with poor prognosis in many cancers. The objective of this study was to characterize the association between SPINK1 overexpression and prostate cancer-specific survival. EXPERIMENTAL DESIGN The study included 879 participants in the U.S. Physicians' Health Study and Health Professionals Follow-Up Study, diagnose...

SPINK1: a new therapeutic target in cancer?

The serine protease inhibitor Kazal type 1 (SPINK1) was initially isolated from bovine pancreas by Kazal and colleagues. A similar protease inhibitor was later identified in human pancreatic juice and called “pancreatic secretory trypsin inhibitor.” By means of immunologic techniques, SPINK1 was later identified as a tumor-associated peptide and isolated from the urine of a patient with ovarian...

Role of the tumor-associated trypsin inhibitor SPINK1 in cancer development.

I n most industrialized countries, prostate cancer is the most common non-skin cancer of men. When detected early, most cases are curable, but for tumors that have metastasized, there is no curative therapy. Pharmaceutical androgen ablation or castration induces remission in most patients with metastatic disease, but if the patient lives long enough, the tumor becomes androgenindependent. In so...

Association of SPINK1 expression and TMPRSS2:ERG fusion with prognosis in endocrine-treated prostate cancer.

PURPOSE The aim of the study was to examine whether TMPRSS2:ERG fusion or SPINK1 protein expression is associated with hormone responsiveness of prostate cancer and can thus be used as a biomarker. EXPERIMENTAL DESIGN Diagnostic needle biopsies from prostate cancer patients primarily treated by endocrine therapy were evaluated for TMPRSS2:ERG fusion with fluorescence in situ hybridization and...
