The effects of TNP-470 on DNA synthesis and the expression of c-myc and cyclin D1 mRNAs were investigated in human umbilical vein endothelial (HUVE) cells synchronized by serum depletion and stimulated with bFGF and serum. DNA synthesis occurring 16 h after stimulation was inhibited when TNP-470 was present from 2 to 6 h after stimulation. C-myc mRNA(More)
This paper demonstrates that B cell lines, as well as normal activated B cells generate and respond to B cell-specific growth factor(s) (BCGF). BCGF derived from B cells (B-BCGF) appears to be distinct from interleukin 1, interleukin 2 (IL 2), B cell stimulatory factor, BCGF-II, interferon-gamma, or transforming growth factor. It acts on activated B cells,(More)
CD2 expression on human B lymphoid progenitor cells was examined. By immunofluorescence analysis, a small fraction of bone marrow B cells was found to express CD2 on their surface. CD2 expression was not demonstrated on peripheral B cells. Epstein-Barr virus-transformed B cell lines derived from fetal liver at 8 weeks of gestation were analyzed to delineate(More)
Production of B cell growth factor (BCGF) from B-chronic lymphocytic leukemia (B-CLL) cells was demonstrated. Freshly isolated monoclonal B-CLL cells expressed surface mu, delta, B1, and Leu 1, but not Ba (an antigen expressed only on activated B cells). Upon stimulation with anti-IgM, they secreted BCGF, which could act on anti-IgM-stimulated autologous(More)
Nuclear antigens are known to trigger off innate and adaptive immune responses. Recent studies have found that the complex of nucleic acids and core histones that are derived from damaged cells may regulate allergic responses. However, no fundamental study has been performed concerning the role of linker histone H1 in mast cell-mediated type I(More)
