Methylation Status of SMG1 Gene Promoter in Multiple Myeloma
Background: Epigenetic modifications, such as methylation can occur in multiple myeloma. SMG1is an important gene involved in cell growth which defect in methylation of its promoter leads to reduction of cell apoptosis and uncontrolled proliferation. In this study, we identified the methylation status of the SMG1 gene promoter in patients with multiple myeloma. Methods: Methylation status of S...
متن کاملCyclin D3 at 6p21 is dysregulated by recurrent chromosomal translocations to immunoglobulin loci in multiple myeloma.
Reciprocal chromosomal translocations, which are mediated by errors in immunoglobulin heavy chain (IgH) switch recombination or somatic hypermutation as plasma cells are generated in germinal centers, are present in most multiple myeloma (MM) tumors. These translocations dysregulate an oncogene that is repositioned in proximity to a strong IgH enhancer. There is a promiscuous array of nonrandom...
متن کاملPost-transcriptional Modifications Contribute to the Upregulation of Cyclin D2 in Multiple Myeloma.
PURPOSE Dysregulation of one of the three D-cyclin genes has been observed in virtually all multiple myeloma tumors. The mechanisms by which CCND2 is upregulated in a set of multiple myeloma are not completely deciphered. We investigated the role of post-transcriptional regulation through the interaction between miRNAs and their binding sites at 3'UTR in CCND2 overexpression in multiple myeloma...
متن کاملInactivation of cyclin D2 gene in prostate cancers by aberrant promoter methylation.
PURPOSE Loss or abnormal expression of Cyclin D2, a crucial cell cycle-regulatory gene, has been described in human cancers; however, data for prostate tumors are lacking. We investigated the epigenetic silencing of Cyclin D2 gene in prostate cancers and correlated the data with clinicopathological features. EXPERIMENTAL DESIGN Cyclin D2 promoter methylation was analyzed in 101 prostate cance...
متن کاملMutually exclusive cyclin-dependent kinase 4/cyclin D1 and cyclin-dependent kinase 6/cyclin D2 pairing inactivates retinoblastoma protein and promotes cell cycle dysregulation in multiple myeloma.
Multiple myeloma, the second most common hematopoietic cancer, ultimately becomes refractory to treatment when self-renewing multiple myeloma cells begin unrestrained proliferation by unknown mechanisms. Here, we show that one, but not more than one, of the three early G(1) D cyclins is elevated in each case of multiple myeloma. Cyclin D1 or D3 expression does not vary in the clinical course, b...
