We report here that the tat gene product of human immunodeficiency virus type 1 was able to protect iymphoblastoid (Jurkat), epithelial (293) and neuronal (PC12) cell lines from apoptotic death induced by serum withdrawal. The rescue from apoptosis by Tat was reflected by an increased expression of Bci-2 protein in tat-positive Jurkat cells with respect to mock-transfected Jurkat cells after 3-...
Most chemotherapy drugs used for the treatment of adult T-cell leukemia-lymphoma (ATL) cause cell death directly by inducing DNA damage, which can be repaired via several DNA repair pathways. Enhanced activity of DNA damage repair systems contributes to ATL resistance to chemotherapies. Targeting DNA repair pathways is a promising strategy for the sensitization of ATL cells to chemotherapeutic ...
In epithelial cells -catenin plays a critical role as a component of the cell-cell adhesion apparatus and as a coactivator of the TCF/LEF (T-cell transcription factor/lymphoid enhancer binding factor) family of transcription factors. Deregulation of -catenin has been implicated in the malignant transformation of cells of epithelial origin. However, a function for -catenin in hematologic maligna...
WISP1, a Wnt-induced secreted protein, has been found to have anticancer activity. ALL is a leading cause of death. Here we investigate the WISP1 effects on ALL Jurkat cells. Cell viability was assessed by CCK-8. Cell cycle and apoptosis were detected by flow cytometry. Mitochondrial membrane potential (MMP) was monitored using TMRM. Generation of reactive oxygen species (ROS) was quantified us...
CD3 antigen is a crucial molecule in T cell signal transduction. Although its expression on cell surface is constitutive, dynamic regulation of TCR-CD3 level is probably the most important mechanism allowing T cells to calibrate their response to different levels of stimuli. In our study we examined the role of two main T cell signal transduction pathways in controlling the surface level of CD3...
Elevated expression of IL-10 has been frequently observed in tumor tissues and tumor-infiltrating cells. We show herein that transcription of the IL-10 gene in primary peripheral T cells and T cell lines is up-regulated upon contact with glioma cells without an induction of apoptosis in those T cells. Glioma-associated IL-10 induction was suppressed by interrupting the engagement of Fas and its...
Chlamydia trachomatis L2 invasively attacks lymphatic and subepithelial tissues of the genital tract during the formation of primary lesions. This subsequently results in lymphadenopathy, and suggests a greater propensity for systemic dissemination. However, whether lymphocytes are a potential vehicle cell for the dissemination of this infection remains unknown. We therefore assessed the growth...
Differently from the antiapoptotic action most commonly assigned to peroxisome proliferators (PPs), we demonstrated that some of them, clofibrate (CF) in particular, display clearcut apoptogenic properties on rat hepatoma cell lines. We and others could confirm that CF as well as various other PPs can induce apoptosis in a variety of cells, including human liver, breast and lung cancer cell lin...
An efficient method for the synthesis of 3-(1H-indol-3-yl)-2-(7,8,12,13-tetraoxa-10-azaspiro[5.7]tridecan-10-yl)propanoic acid) via condensation 7,8,10,12,13-pentaoxaspiro[5.7]tridecane with tryptophan under action a catalyst based on Sm(NO3)3·6H2O has been developed. A high cytotoxic activity eight-membered azadiperoxide against tumor cells Jurkat, K562, U937, and HL60 was established. Additio...
