RB activation defect in tumor cell lines.
Activation of the retinoblastoma (RB) protein through dephosphorylation arises in cells upon exit from M phase and in response to environmental stresses, including DNA damage. We provide here for the first time evidence that these responses are co-ordinately affected in a subset of tumor derived cell lines. We find that RB dephosphorylation is not apparent in these cells during progression into...
متن کاملInduction of apoptosis in human tumor cell lines by platelets
Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
متن کاملDown-regulation of HSP40 gene family following OCT4B1 suppression in human tumor cell lines
Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human tumor cell lines. Materials and Met...
متن کاملAssessment of Cytotoxicity of Dimethyl Sulfoxide in Human Hematopoietic Tumor Cell Lines
Background: Dimethyl Sulfoxide (DMSO) is a solvent most broadly used as a cryopreservative agent. Antitumor effects of DMSO is a recently recognized phenomenon. In this study, cytotoxic effects of DMSO on human monocytes and T leukemic cell lines has been investigated in vitro. Methods: Human leukemic T cells (Molt-4 and Jurkat) and monocytes (U937 and THP1) were cultured in complete RPMI medi...
