Abstract:
Tumor necrosis factor alpha (TNF-alpha) and its receptors (TNFRI and TNFRII) which exist in soluble form as a product of cleavage of the extracellular domain of membrane integrated receptors, still rise debate about their importance. It was reported that TNF-alpha has numerous actions in diseases such as inflammation, autoimmunity, infectious diseases, septic shock and many types of cancer [1, 2]. Several authors have reported the significance of sTNFRI level in serum of cancer patients [3, 4]. This study was performed in collaboration with the Institute of Oncology of Slovenia. At least two different mouse monoclonal antibodies (MAbs) against human sTNFRI have been prepared to obtain a sensitive and reliable sandwich ELISA. It was compared with commercially available R&D and Endogen ELISAs for the determination of sTNFRI. Groups of patients with different stages of melanoma and epithelial ovarian carcinoma were tested and their clinical records were reexamined. Levels of sTNFRI were measured and compared with the normal serum levels of sTNFRI.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
