Multiple myeloma (MM) is a non-curable tumor developing in the bone marrow (BM). The BM microenvironment rich in hematopoietic precursors is suspected to have a role in MM development. Here we show that a proliferation-inducing ligand (APRIL) mediated in vivo

Epidemiological studies indicate that statins, cholesterol-lowering drugs, prevent aggressive prostate cancer and other types of cancer. Employing essentially non-prostate cell lines, we previously showed that statins rapidly downregulate nuclear levels of phosphorylated Akt via P2X7, a purinergic receptor recently implicated

Hematopoietic stem cells (HSCs) possess the ability to generate all hematopoietic cell types and to self-renew over long periods, but the mechanisms that regulate their unique properties are incompletely understood. Herein, we show that homozygous deletion of the miR-29a/b-1 bicistron

Alloimmune antenatal membranous nephropathy (MN) during pregnancy results from antibodies produced by a neutral endopeptidase (NEP)-deficient mother. Here we report two recent cases that provide clues to the severity of renal disease. Mothers of the two children had circulating antibodies

Rheumatoid arthritis (RA) is thought to be a T cell-mediated disease, based on its strong association with HLA class II alleles, clinical responsiveness to T cell-directed therapies, and the presence of CD4+ T cells in rheumatoid joints. The presence of
