Paracrine rather than autocrine regulation of myeloma-cell growth and differentiation by interleukin-6.
To explore the mechanisms involved in the pathogenesis of human multiple myeloma (MM), we investigated the potential role of interleukin-6 (IL-6), a B-cell differentiation factor in humans, and a growth factor for rat/mouse heterohybridomas and murine plasmacytomas. Using a heterohybridoma assay, we found that two well-documented human myeloma cell lines, RPMI 8226 and U266, did not secrete IL-...
متن کاملInterleukin-1 accelerates autocrine growth of myeloma cells through interleukin-6 in human myeloma.
Recombinant interleukin 1 alpha (rIL-1 alpha) augmented proliferation of freshly isolated myeloma cells as well as B-cell stimulatory factor 2 (BSF-2)/interleukin-6 (IL-6). Recombinant IL-1 alpha-induced proliferation was partially inhibited by anti-IL-6 antibody. In the culture supernatants of rIL-1 alpha-stimulated myeloma cells, IL-6 activities, which were measured by using an IL-6-dependent...
متن کاملCharacterization of an interleukin-6-mediated autocrine growth loop in the human multiple myeloma cell line, U266.
It has been reported recently that freshly isolated human myeloma cell cultures proliferate in response to added interleukin-6 (IL-6). Endogenous levels of IL-6 found in the same cultures suggested that an autocrine growth loop may contribute to cell growth. However, the lack of homogenous cell populations in primary myeloma cultures has made it difficult to distinguish between paracrine and au...
متن کاملFGF: an autocrine regulator of human lens cell growth independent of added stimuli.
PURPOSE Posterior capsule opacification (PCO) arises because of a persistent growth of lens epithelial cells. Cultured human lens cells residing on their native collagen capsule and maintained in serum-free medium actively grow and thus show an intrinsic capacity for regulation. In the present study, the authors investigated the role of the putative FGF autocrine system in human capsular bags. ...
متن کاملInterleukin 8: an autocrine growth factor for malignant mesothelioma.
Interleukin 8 (IL-8) is a potent chemokine that also has a direct growth-potentiating effect on certain tumors. In the present study, we determined IL-8 levels in human malignant mesothelioma (MM) effusions and congestive heart failure pleural fluids. We also investigated antigenic IL-8 production by different MM cell lines, and we describe the role of IL-8 in the autocrine growth regulation of...
