Differentiation of human leukemias in response to 12-0-tetradecanoylphorbol-13-acetate in vitro.
Leukemic cells from patients with acute myeloid leukemia underwent morphological, functional, and histochemical changes within 24-48 hr after treatment with 1.6 x 10-18 M 12-0-tetradecanoylphorbol-13-acetate (TPA). The changes included adhesion to the plastic substrate, a 4-6-fold increase in the number of phagocytic cells, and an increase in the number of alpha-naphthyl-acetate esterase (alpha...
متن کامل12-O-tetradecanoylphorbol-13-acetate (TPA) increases murine intestinal crypt stem cell survival following radiation injury
Radiation enteropathy is a common complication in cancer patients following radiation therapy. Thus, there is a need for agents that can protect the intestinal epithelium against radiation. 12-O-tetradecanoylphorbol-13-acetate (TPA) has been shown to induce differentiation and/or apoptosis in multiple cell lines and primary cells. In the current report, we studied the function of TPA in radiati...
متن کاملSuppression of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin inflammation in mice by transduced Tat-Annexin protein.
We examined that the protective effects of ANX1 on 12-O-tetradecanoylphorbol- 13-acetate (TPA)-induced skin inflammation in animal models using a Tat-ANX1 protein. Topical application of the Tat-ANX1 protein markedly inhibited TPAinduced ear edema and expression levels of cyclooxygenase-2 (COX-2) as well as pro-inflammatory cytokines such as interleukin- 1 beta (IL-1 β), IL-6, and tumor necrosi...
متن کاملStimulation of CEACAM1 expression by 12-O-tetradecanoylphorbol-13-acetate (TPA) and calcium ionophore A23187 in endometrial carcinoma cells.
Downregulation of carcinoembryonic antigen-related cell adhesion molecule (CEACAM1), a cell adhesion molecule with tumor suppressing properties has been observed in a high percentage of carcinomas of the endometrium and other malignancies. The mechanisms for the dysregulation and the role of hormones and cytokines on the expression of CEACAM1 in endometrial carcinomas is unknown. We therefore s...
متن کاملTransient protection of cultured human cells against antitumor agents by 12-O-tetradecanoylphorbol-13-acetate.
The tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) has been shown in cell cultures to enhance the frequency of resistance to methotrexate. However, we found that TPA could also partially protect human KB cells over a short time (72 h) from the cytotoxicity of several antitumor agents, including 4'-demethylepipodophyllotoxin 9-(4,6-O-ethylidene)-beta-D-glucopyranoside (VP-16), vincris...
