Expression of FAS/APO 1/CD 95 in thyroid tumors.

Anti-Fas on nonhematopoietic tumors: levels of Fas/APO-1 and bcl-2 are not predictive of biological responsiveness.

Fas/APO-1 is a cell surface protein known to trigger apoptosis in a variety of cell types upon specific antibody binding. Although extensively studied on normal and malignant hematopoietic cells, little is known about Fas/APO-1 on nonhematopoietic cells. In the study presented here, we have examined Fas/APO-1 expression and function on 11 human tumors of nonhematopoietic origin. By flow cytomet...

Protein Kinase C Regulates Fas ( CD 95 / APO - 1 ) Expression 1

نقش ارسنیک در القای آپوپتوزیس از مسیر Fas در بیماران لوسمی حاد پرومیلوسیتی با جابه‌جایی کروموزومی

Acute promyelocytic leukemia (APL) is a sub-type of acute myelogenous leukemia (AML) which occurs in about 10-15% of patients with AML. Approximately 20-30% of these patients, who are treated with the current standard All trans retinoic Acid(ATRA) and anthracyclines-based chemotherapy regimen, suffer relapse in less than a year. Arsenic trioxide (ATO), as a single agent, can induce ...

Protooncogene bcl-2 gene transfer abrogates Fas/APO-1 antibody-mediated apoptosis of human malignant glioma cells and confers resistance to chemotherapeutic drugs and therapeutic irradiation.

The majority of human malignant glioma cells express Fas/APO-1 and are susceptible to Fas/APO-1 antibody-mediated apoptosis in vitro. The sensitivity of Fas/APO-1-positive glioma cell lines to Fas/APO-1 antibody-mediated killing correlates inversely with the constitutive expression of the antiapoptotic protooncogene bcl-2. Here we report that BCL-2 protein expression of human glial tumors in vi...
