Short-term culture of acute myelogenous leukemia patient's remission lymphocytes with inactivated autologous leukemic blast cells plus allogeneic lymphocytes, generated effector T lymphocytes which were cytotoxic for the specific autologous blast cell in 11 of 14 patients studied. Experiments using Daudi and Molt 4 lymphoblastoid cell lines as third-party helper cell suggest that an HLA D locu...
In this protocol, the in situ detection of hydrogen peroxide (one of several reactive oxygen species) is described in mature Arabidopsis rosette leaves by staining with 3,3'-diaminobenzidine (DAB) using an adaptation of previous methods (Thordal-Christensen et al., 1997; Bindschedler et al., 2006; Daudi et al., 2012). DAB is oxidized by hydrogen peroxide in the presence of some haem-containing ...
We describe a novel pharmacological activity of the gentian root, an ingredient of Chinese medicines. Root extract from Gentiana triflora triggered cell death of human Daudi cells in culture. In addition, daily administration of the extract to mice inhibited growth of implanted solid tumors. Extract treatment of cultured cells resulted in the appearance of shranken, fragmented, or condensed cel...
In vitro killing of the human Daudi cell line by either univalent [F(ab')] or divalent (IgG) forms of rabbit anti-human Ig (RAHIg) coupled to ricin A chain can be specifically potentiated by a "piggyback" treatment with ricin B chain coupled to goat anti-rabbit Ig (GARIg). When cells are treated with univalent immunotoxin (IT) [F(ab') RAHIg-A] and then cultured, IT can be detected on the cell s...
Interferon-induced gene expression was analyzed in wild-type and interferon-resistant Daudi cells. Two classes of alpha-interferon-induced mRNAs and proteins were observed: those that were similarly induced in both types of cell and those that were induced only in the wild-type cells. Furthermore, the level of c-myc mRNA decreased in the wild-type but not in the resistant cells. This differenti...
Isolation of Daudi Cells with Reduced Sensitivity to Interferon. II. On The Mechanisms of Resistance
The presence of body-like structures in nuclei from interferon alpha-treated Daudi cells has been shown on the ultrastructural level, by the use of different staining methods. The degree of their rearrangement in the nucleoplasm seems to be dependent on the time of interferon treatment. Since this morphological evidence has been found to be preceded by a slowing down of RNA transcriptional mach...
