چکیده

Multiple myeloma (MM) is the second most common malignancy in the hematologic system, which is characterized by accumulation of plasma cells in bone marrow. Pterostilbene (PTE) is a natural dimethylated analog of resveratrol, which has anti-oxidant, anti-inflammatory and anti-tumor properties. In the present study, we examined the anti-tumor effect of PTE on MM cell lines both in vitro and in vivo using the cell counting kit (CCK)-8, apoptosis assays, cell cycle analysis, reactive oxygen species (ROS) generation, JC-1 mitochondrial membrane potential assay, Western blotting and tumor xenograft models. The results demonstrated that PTE induces apoptosis in the H929 cell line and causes cell cycle arrest at G0/G1 phase by enhancing ROS generation and reducing mitochondrial membrane potential. The anti-tumor effect of PTE may be caused by the activation of the extracellular regulated protein kinases (ERK) 1/2 and c-Jun N-terminal kinase (JNK) signaling pathways. Additionally, mice treated with PTE by intraperitoneal injection demonstrated reduced tumor volume. Taken together, the results of this study indicate that the anti-tumor effect of PTE on MM cells may provide a new therapeutic option for MM patients.

The effect of down-regulation of CCL5 on lipopolysaccharide-induced WI-38 fibroblast injury: a potential role for infantile pneumonia

Objective(s): Aberrant expression of CCL5 has been found in several kinds of inflammatory diseases, and the roles of CCL5 in these diseases have also been reported. However, the role of CCL5 in infantile pneumonia is still unclear. Thus, the function and acting mechanism of CCL5 in the in vitro model of infantile pneumonia were researched in this study. Materials and Methods: Human fetal lung f...

In vitro Effect of Pomalidomide on Bone Marrow Mononuclear Cells from Multiple Myeloma Patients

Background: Many features of anticancer drugs, including cytotoxicity and/or cytokine induction, are studied using cell lines orhuman blood leukocytes. However, in a disease such as multiple myeloma, most cancerous cells are resided within bone marrowmononuclear cells. In the present study, we investigated the effect of pomalidomide on apoptosis and IL-2 production of bonemarrow mononuclear cel...

The human immunodeficiency virus-1 protease inhibitor nelfinavir impairs proteasome activity and inhibits the proliferation of multiple myeloma cells in vitro and in vivo.

BACKGROUND Multiple myeloma is characterized by the accumulation of tumor plasma cells in the bone marrow. Despite therapeutic improvements brought by proteasome inhibitors such as bortezomib, myeloma remains an incurable disease. In a variety of human cancers, human immunodeficiency virus protease inhibitors (e.g. nelfinavir) effectively inhibit tumor progression, but their impact on myeloma i...

Interruption of the Ras/MEK/ERK signaling cascade enhances Chk1 inhibitor-induced DNA damage in vitro and in vivo in human multiple myeloma cells.

The role of the Ras/MEK/ERK pathway was examined in relation to DNA damage in human multiple myeloma (MM) cells exposed to Chk1 inhibitors in vitro and in vivo. Exposure of various MM cells to marginally toxic concentrations of the Chk1 inhibitors UCN-01 or Chk1i modestly induced DNA damage, accompanied by Ras and ERK1/2 activation. Interruption of these events by pharmacologic (eg, the farnesy...
