Syndecan Family Gene and Protein Expression and Their Prognostic Values for Prostate Cancer.

Prostate cancer (PCa) is the leading cause of cancer-associated mortality in men, and new biomarkers are still needed. The expression pattern and protein tissue localization of proteoglycans of the syndecan family (SDC 1-4) and syntenin-1 (SDCBP) were determined in normal and prostatic tumor tissue from two genetically engineered mouse models and human prostate tumors. Studies were validated using SDC 1-4 and SDCBP mRNA levels and patient survival data from The Cancer Genome Atlas and CamCAP databases.

Sulfiredoxin as a Potential Therapeutic Target for Advanced and Metastatic Prostate Cancer.

The incidence of prostate cancer (PCa) is increasing, and it is currently the second most frequent cause of death by cancer in men. Despite advancements in cancer therapies, new therapeutic approaches are still needed for treatment-refractory advanced metastatic PCa. Cross-species analysis presents a robust strategy for the discovery of new potential therapeutic targets.

Correlation analysis of c-myc, p21(WAF/CIP1), p53, C-erbB-2 and COX-2 proteins in esophageal squamous cell carcinoma.

Esophageal cancer is one of the most frequently occurring malignancies and the seventh leading cause of cancer-related deaths in the world. Esophageal squamous cell carcinoma (ESCC) is the most common histological type of esophageal cancer worldwide. Our goal in this study was to detect c-myc, p21(WAF/CIP1), p53, C-erbB-2 and COX-2 immuno-expression in ESCC.

Amitriptyline aggravates the fibrosis process in a rat model of infravesical obstruction.

Infravesical obstruction (IVO) secondary to benign prostatic hypertrophy can affect up to 50% of men over 50 years old and may cause serious and irreversible alterations throughout the urinary tract, especially in the bladder. Therapeutic approaches are currently limited. Amitriptyline has recently been described as an analgesic, anti-inflammatory and myorelaxant in some experimental models.

The extrinsic apoptotic signaling pathway in gastric adenocarcinomas assessed by tissue microarray.

The purpose of this investigation was to analyze the immunoexpression of FasL, Fas, FADD, cleaved caspase 8, and cleaved caspase 3 in gastric cancer. Formalin-fixed and paraffin-embedded gastric adenocarcinoma tissues from 87 patients, including adjacent normal tissues, were included on tissue microarray by immunohistochemistry. The tumor and the adjacent normal tissues were positive for FasL in 66.

The intrinsic apoptotic signaling pathway in gastric adenocarcinomas of Brazilian patients: Immunoexpression of the Bcl-2 family (Bcl-2, Bcl-x, Bak, Bax, Bad) determined by tissue microarray analysis.

This study was undertaken to investigate the immunoexpression of Bcl-2 family proteins (Bcl-2, Bcl-x, Bax, Bak and Bad) and to evaluate the correlation between the immunoexpression of these proteins and that of cleaved caspase 3, Ki-67 and p53. A tissue microarray (TMA) paraffin block was constructed using gastric carcinoma tissue (test group) and adjacent normal gastric mucosa (control group) from 87 patients who had not previously undergone radiotherapy or chemotherapy. Sections from the TMA block (4 µm) were subjected to immunohistochemistry for Bcl-2, Bcl-x, Bax, Bak, Bad, p53, Ki-67 and cleaved caspase-3.
