Okadaic acid, dinophysistoxin-1 (35-methylokadaic acid), and calyculin A are the okadaic acid class of non-12-O-tetradecanoylphorbol-13-acetate (TPA)-type tumor promoters, which do not bind to the phorbol ester receptors in cell membranes or activate protein kinase C in vitro. They have potent tumor-promoting activities on mouse skin, as strong as TPA-type(More)
We retrospectively reviewed 104 biopsy specimens of previously untreated skin acute graft-versus-host disease (GVHD) within 100 days after allogeneic stem cell transplantation, and analyzed the relationship between types of infiltrating cells and clinical outcomes. Counting the total number of CD8(+) T cells, CD163(+) macrophages, and CD1a(+) dendritic(More)
A polyclonal antibody was raised against a recombinant ligand binding domain construct of the human retinoid X receptor (RXR) alpha. This antibody reacted with an endogenous 54 kDa nuclear protein from human hepatoma-derived HuH7 cells in immunoblot analyses. Immunoblotting of nuclear proteins from human hepatocellular carcinomas (HCCs) and their(More)
Stromal cells and osteoblasts play major roles in forming and modulating the bone marrow (BM) hematopoietic microenvironment. We have reported that FGF2 compromises stromal cell support of normal hematopoiesis. Here, we examined the effects of FGF2 on the leukemia microenvironment. In vitro, FGF2 significantly decreased the number of stromal-dependent and(More)
Macrophage infiltration of skin GVHD lesions correlates directly with disease severity, but the mechanisms underlying this relationship remain unclear and GVHD with many macrophages is a therapeutic challenge. Here, we characterize the macrophages involved in GVHD and report that dexamethasone palmitate (DP), a liposteroid, can ameliorate such GVHD by(More)
