PURPOSE Salvia officinalis L., also known as Maryam Goli, is one of the native plants used to Persian medicinal herbs. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized crude methanol extracts prepared from Salvia officinalis L., on a non-Hodgkin's B-cell lymphoma (Raji) and human leukemic monocyte lymphoma (U937), Human acute myelocytic leuke...

Methotrexate (MTX)-resistant sublines of malignant human cells were selected in vitro by stepwise increase in drug concen tration in the medium. By this procedure a subline of Burkitt's lymphoma cells (RAJI) was made 290-fold resistant (RAJI/MTXR), T-cell leukemia cells (CCRF-CEM) were obtained 210-fold resistant (CEM/MTX-R), and 3 MTX-resistant human osteosarcoma lines were selected: TE-85/MTX...

BACKGROUND Anti-CD20 monoclonal antibody treatment has not only increased survival and cure rates in many non-Hodgkin lymphomas, but also has prompted an explosion in the development of novel antibodies and biologically active substances with specific cellular targets in the field of malignancies treatment. Since the robust immune responses are elicited by the gene-modified T cells, gene based ...

The alkylating agents represent one of the most important classes of antitumor agents and play a major role in combination with other agents in the curative chemotherapy of selected human cancers. By repeatedly exposing cells to escalating doses of an alkylating agent, we have developed four human tumor cell lines which are relatively stably resistant to the drug with which the culture was trea...

the b-cell cd20 antigen is one of the most reliable surface targets in immunotherapy of b lymphoma. in this project, we studied the production and characterization of a new monoclonal antibody against chimeric human cd20 extra loops (hcd20 exl). the results showed that clone c12h, igg2/k isotype reacted with the antigen in elisa and immunoblot. the kd value was  found to be 2×10-9m and flow cyt...

Lymphoma is not a common focus for viral therapy as many researchers do not consider lymphoma as a suitable target for viral vectors. In the present study, the infection, replication and cytotoxicity of herpes simplex virus (HSV) and adenovirus vectors were screened and evaluated in different lymphoma cell lines. Three recombinant viruses, BAC-HSV-1-eGFP, Adv-eGFP and an NV1020-like oncolytic H...

BACKGROUND Exosomes secreted by tumor cells contain specific antigens that may have immunotherapeutic purposes. The aim of this study was to characterize the proteomic content of lymphoma cell-derived exosomes (LCEXs). METHODS In this study, exosomes derived from Raji cells (EXO(Raji)) were purified and proteins of EXO(Raji) were separated by one-dimensional sodium dodecyl sulfate polyacrylam...

Coriolus versicolor (CV), also known as Yunzhi, is one of the commonly used Chinese medicinal herbs. Although recent studies have demonstrated its antitumour activities on cancer cells in vitro and in vivo, the exact mechanism is not fully elucidated. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized aqueous ethanol extract prepared from Corio...

Methotrexate (MTX)-resistant sublines of malignant human cells were selected in vitro by stepwise increase in drug concentration in the medium. By this procedure a subline of Burkitt's lymphoma cells (RAJI) was made 290-fold resistant (RAJI/MTX-R), T-cell leukemia cells (CCRF-CEM) were obtained 210-fold resistant (CEM/MTX-R), and 3 MTX-resistant human osteosarcoma lines were selected: TE-85/MTX...

Burkitt lymphoma (BL) is a highly malignant non-Hodgkin's lymphoma that is closely related to the abnormal expression of genes. Familial acute myelogenous leukemia related factor (FAMLF; GenBank accession No. EF413001.1) is a novel gene that was cloned by our research group, and miR-181b is located in the intron of the FAMLF gene. To verify the role of miR-181b and FAMLF in BL, RNAhybrid softwa...
