ABSTRACT
BACKGROUND:
The activation of Fas/Fas ligand (FasL) and DR4-DR5/tumor necrosis factor-related-apoptosis-inducing ligand (TRAIL) pathways in cancer cells triggers apoptosis. The objective of this study was to investigate the prognostic value of soluble FasL (sFasL) and soluble (sTRAIL) in the serum of patients with bladder cancer.METHODS:
The sFasL and sTRAIL levels in the sera of patients with bladder cancer or healthy donors were determined using the enzyme-linked immunosorbent assay. Micro-culture tetrazolium viability assay and Western blot were used to analyze cell cytotoxicity and death receptors protein expression respectively.RESULTS:
Whether no difference in sTRAIL levels was seen between patients and controls, the level of sFasL was higher in patients than that in healthy donors. According to, sFasL level was the highest in the serum of patients with superficial stage or low- and medium-grade cancer. Moreover, sFasL in patients with superficial noninvasive bladder tumors or low- and medium-grade cancers was higher than that in patients with invasive carcinomas and high-grade cancers. Patients with high levels of sFasL survive longer than those with low levels, probably related to the cytotoxic potential of FasL preserved in its soluble form.CONCLUSION:
The data suggest that monitoring the level of sFasL and its cytotoxic activity could be a prognostic marker in the follow-up of patients with bladder cancer.Palavras-chave
