Impaired Fas-mediated apoptosis is associated with poor clinical outcomes and cancer chemoresistance. Soluble Fas receptor (sFas), produced by skipping of exon 6, inhibits apoptosis by sequestering Fas ligand. Serum sFas is associated with poor prognosis of non-Hodgkin's lymphomas. We found that the alternative splicing of Fas in lymphomas is tightly(More)
BACKGROUND Resistance to Fas-mediated apoptosis limits the efficacy of currently available chemotherapy regimens. We identified CD74, which is known to be overexpressed in hematological malignancies, as one of the factors interfering with Fas-mediated apoptosis. METHODS CD74 expression was suppressed in human B-lymphoma cell lines, BJAB and Raji, by(More)
Resistance to Fas-mediated apoptosis is associated with poor cancer outcomes and chemoresistance. To elucidate potential mechanisms of defective Fas signaling, we screened primary lymphoma cell extracts for Fas-associated proteins that would have the potential to regulate Fas signaling. An activation-resistant Fas complex selectively included nucleolin. We(More)
BACKGROUND Herpesvirus 8 (HHV-8) oncoprotein K1 is linked to lymphoproliferation and suppression of apoptosis mediated by the Fas death receptor. Expression of K1 in transgenic mice induces accumulation of lymphoid tissue cells and lymphoma. METHODS To examine how K1 and Fas interact to suppress apoptosis, K1-Fas binding was studied in human embryonic(More)
Defective Fas signaling leads to resistance to various anticancer therapies. Presence of potential inhibitors of Fas which could block Fas signaling can explain cancer cells resistance to apoptosis. We identified promyelocytic leukemia protein (PML) as a Fas-interacting protein using mass spectrometry analysis. The function of PML is blocked by its(More)
BACKGROUND Although significant progress has been made in the treatment of lymphomas, many lymphomas exhibit resistance to cell death, suggesting a defective Fas signaling, which remains poorly understood. We previously reported that cells expressing the K1 protein of human herpesvirus 8 (HHV-8) resist death through the complex formation of the Ig-like(More)
Background Infection with human herpesvirus 8 (HHV-8), also known as Kaposi sarcoma associated herpesvirus, is associated with the development of primary effusion lymphoma and Kaposi sarcoma. A transmembrane protein of HHV-8, K1, is readily expressed in these tumors, and the expression of K1 alone causes hyperplasia of lymph nodes and lymphomas in mice. The(More)
Background Human herpesvirus 8 (HHV-8) infection is associated with the development of primary effusion lymphoma, Kaposi's sarcoma, and multicentric Castleman's disease. The K1 gene of HHV-8 is expressed in tumor cells as a transmembrane protein with an immunoglobulin-like domain in its ectodomain and an immunoreceptor tyrosine-based activation motif(More)
Anthracyclines have been a cornerstone in the cure of diffuse large B-cell lymphoma (DLBCL) and other hematological cancers. The ability of anthracyclines to eliminate DLBCL depends on the presence of topoisomerase-II-alpha (TopIIA), a DNA repair enzyme complex. We identified nucleolin as a novel binding partner of TopIIA. Abrogation of nucleolin sensitized(More)
a dog, which was afterwards proved to have been mad, in passing, suddenly turned round and bit him on the ball of the left thumb. After a delay of several hours the wound was cauterized. It healed slowly, and for long afterwards irregular shooting pains, extending from the cicatrix along the inside of the arm, troubled him. Between the receipt of the former(More)
