Multiple myeloma (MM) is a disease that affects plasma cells and can lead to devastating clinical features such as anemia, lytic bone lesions, hypercalcemia, and renal disease. An enhanced understanding of MM disease mechanisms has led to new more targeted treatments. There is now a plethora of treatments available for MM. In this review article, our aim is to discuss many of the novel agents t...

Primary plasma cell leukemia (PPCL) is a rare aggressive variant of plasma cell disorder and frequently presents with extramedullary disease. Central nervous system (CNS) involvement with PPCL has an extremely poor prognosis. We describe a 46-year-old man with PPCL treated with a combination of lenalidomide, bortezomib, and dexamethasone as induction therapy following upfront allogeneic stem ce...

The immunomodulatory drugs (IMiDs) lenalidomide and pomalidomide yield high response rates in patients with multiple myeloma, but the use of IMiDs in multiple myeloma is associated with neutropenia and increased risk for venous thromboembolism (VTE) by mechanisms that are unknown. We show that IMiDs down-regulate PU.1, a key transcription factor involved in granulocyte differentiation in vitro ...

Glutamine synthetase (GS) plays an essential role in metabolism by catalyzing the synthesis of glutamine from glutamate and ammonia. Our recent study showed that CRBN, a direct protein target for the teratogenic and antitumor activities of immunomodulatory drugs such as thalidomide, lenalidomide, and pomalidomide, recognizes an acetyl degron of GS, resulting in ubiquitylation and degradation of...

Contemporary treatments have greatly extended survival in multiple myeloma (MM), and when relapse occurs, clinicians have numerous effective options at their disposal. Genetic profiling of the tumor allows for risk stratification that guides treatment selection. “Survival is improving, thanks to new treatments,” according to Angela Mayo, MS, PA-C. The proteasome inhibitors—bortezomib (Velcade),...

The aim of our research is to identify potential genes associated with Ductal carcinoma in situ (DCIS) through microarrays. The microarray dataset GS54665 were downloaded from the GEO(Gene Expression Omnibus) database. Dysregulated genes were screened and their associations with DCIS was analyzed by comprehensive bioinformatics tools. A total of 649 differential expression genes were identified...
