Reciprocal co-expression of Fas and Fas ligand in human cholangiocarcinoma.
We have previously characterized the role of Fas in tumorigenesis using two cholangiocarcinoma cell lines expressing high (Fas(H)) and low (Fas(L)) levels of Fas. Here we further characterize Fas ligand (FasL) expression and function in these two cell lines. The Fas(L) cells expressed a high level of FasL, whereas the Fas(H) cells expressed a low level of FasL showing reciprocal expression of F...
متن کاملFas and Fas-ligand expression in human pancreatic cancer.
OBJECTIVE To investigate Fas and FasL expression in pancreatic tissues and cultured pancreatic cancer cell lines, and to assess the ability of anti-Fas antibodies to induce apoptosis. SUMMARY BACKGROUND DATA Activation of the Fas receptor by Fas-ligand (FasL) results in apoptosis, and dysregulation of this pathway may contribute to abnormal cell proliferation. METHODS Northern blotting and ...
متن کاملStatus of FAS and FAS Ligand Gene Polymorphisms in Patients wi th Breast Cancer in Northeastern IRAN
Background: The First apoptosis signal (FAS) and First apoptosis signal ligand (FASL) genes initiate the apoptosis pathway, playing a central role in the tumor growth and metastasis. Gene polymorphisms including -1377 G/A in the promoter region of FAS and -844 C/T in the promoter region of FASL have shown to change the transcription activities of these genes. Methods: In this study we evalua...
متن کاملDifferential expressions of Fas and Fas ligand in human placenta.
To investigate the expressions of Fas and Fas ligand (FasL) in human placenta, we studied the expressions of Fas and FasL in placenta with RT-PCR, immunoblotting and immunostaining. We observed amplified products of Fas and FasL transcripts, the band of Fas (52 kDa) and multiple bands of FasL (42-52 kDa) in placenta. Fas and FasL localized mainly on fetal vessels and on syncytiotrophoblasts res...
متن کاملFas and Fas ligand expression in cystic fibrosis airway epithelium.
BACKGROUND Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene and defective expression of CFTR protein in epithelial cells. The main cause of mortality in CF is linked to chronic inflammatory and infectious airway processes. Recent studies have suggested perturbations in the apoptotic process in CF cell lines and ...
