Frequency of FLT3 ITD and FLT3 TKD Mutations in Multiple Myeloma Patients (A Case Control Study)
Background and Aims: Multiple myeloma is a malignant proliferation of plasma cells derived from a single clone. The tumor, its products and the host response lead to organ damages. Some factors that are responsible in its pathogenesis are recognized. As FMS like Tyrosine Kinase 3 receptor (FLT3) mutation has been proved as a determining factor in leukemic patients the goal of this study was to ...
متن کاملSphingosine kinase 2 inhibition synergises with bortezomib to target myeloma by enhancing endoplasmic reticulum stress
The proteasome inhibitor bortezomib has proven to be invaluable in the treatment of myeloma. By exploiting the inherent high immunoglobulin protein production of malignant plasma cells, bortezomib induces endoplasmic reticulum (ER) stress and the unfolded protein response (UPR), resulting in myeloma cell death. In most cases, however, the disease remains incurable highlighting the need for new ...
متن کاملSphingosine Kinase-1 Protects Multiple Myeloma from Apoptosis Driven by Cancer-Specific Inhibition of RTKs.
Activation of acid sphingomyelinase (ASM) leads to ceramide accumulation and induces apoptotic cell death in cancer cells. In the present study, we demonstrate that the activation of ASM by targeting cancer-overexpressed 67-kDa laminin receptors (67LR) induces lipid raft disruption and inhibits receptor tyrosine kinase (RTK) activation in multiple myeloma cells. Sphingosine kinase 1 (SphK1), a ...
متن کاملMethylation and mRNA expression levels of P15, death-associated protein kinase, and suppressor of cytokine signaling-1 genes in multiple myeloma
Objective(s): The aim of this study was to investigate the methylation status and mRNA expression levels of P15, death-associated protein kinase (DAPK), and suppressor of cytokine signaling-1 (SOCS1) genes in multiple myeloma (MM). Materials and Methods: The bone marrow samples of 54 MM patients were collected and the methylation status of the P15, DAPK, and SOCS1 gene promoter regions was dete...
متن کاملInhibition of sphingosine kinase 2 downregulates the expression of c-Myc and Mcl-1 and induces apoptosis in multiple myeloma.
Sphingolipid metabolism is being increasingly recognized as a key pathway in regulating cancer cell survival and proliferation. However, very little is known about its role in multiple myeloma (MM). We investigated the potential of targeting sphingosine kinase 2 (SK2) for the treatment of MM. We found that SK2 was overexpressed in MM cell lines and in primary human bone marrow (BM) CD1381 myelo...
