Fas/FasL expression in colorectal cancer. An immunohistochemical study.
The objective of the current study was to assess the expression of Fas ligand (FasL) and Fas receptor (FasR) as the proteins of the post-mitochondrial apoptotic pathway in colorectal carcinoma and to investigate correlations between their expression and chosen clinico-pathological parameters. The pr...
