Trefoil factor 3 is overexpressed in human prostate cancer
Abstract
The trefoil factors are secreted peptides produced by normal intestinal mucosa. Members of the trefoil family are overexpressed in a variety of cancers and are associated with tumor invasion, resistance to apoptosis, and metastasis. Recent cDNA array analyses suggest that human intestinal trefoil factor 3 (TFF3) may be overexpressed in human prostate cancer. Immunohistochemistry was performed on a prostate cancer tissue microarray containing tumor tissue samples from 246 primary radical retropubic prostatectomy cases with antibodies specific for TFF3. Prostatic intraepithelial neoplasia (PIN), benign prostatic hyperplasia (BPH), and morphologically normal prostatic epithelium were represented on this array. Additionally, 18 metastatic lesions were also stained. Two independent pathologists scored the tissue arrays, with positive cases defined as those containing TFF3 staining in a majority of target cells within any spots representing the appropriate designated histology. Forty-two percent of 236 cases containing prostate cancer stained positive for TFF3, while only 10% of 145 cases containing normal tissue and 18% of 91 cases containing BPH, stained positive. Seven of 18 (39%) metastatic lesions analyzed stained positive. Alth...Continue Reading

Apoptosis in Cancer
Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
