(Submitter supplied) Ophelia syndrome is characterized by the coincidence of severe neuropsychiatric symptoms, classical Hodgkin lymphoma, and the presence of antibodies to the metabotropic glutamate 5 receptor (mGluR5). Little is known about the pathogenetic link between these symptoms and the role anti-mGluR5-antibodies play. We investigated lymphoma tissue from patients with Ophelia syndrome and with isolated classical Hodgkin lymphoma by quantitative immunocytochemistry for mGluR5-expression. more...

(Submitter supplied) Disease relapse and resistance to chemotherapy represent challenging issues in a subset of Hodgkin Lymphoma (HL) patients. Activity and mechanism(s) of action of a novel PI3K/ERK dual inhibitor AEZS-136 (Æterna Zentaris GmbH, Germany, EU) were examined in L-540, SUP-HD1, KM-H2 and L-428 cell lines. Despite exposure to AEZS-136 induced a significant cell growth inhibition (range, 30-80%), levels of caspase-independent cell death and mitochondrial dysfunction, were only observed in L-540 (62 ±9 vs 14 ±3%, P ≤.0001) and SUP-HD1 (46 ±2% vs 15 ±2%, P ≤.0001) cells. more...

(Submitter supplied) Tumor-associated macrophages (TAMs) are involved in the pathogenesis of Hodgkin lymphoma (HL) and correlate with negative prognosis. The phosphatidylinositol 3-kinase (PI3K) mediates tumor and endothelial cell survival, and macrophage activation. As PI3Kδ and PI3Kγ are constitutively activated in HL, we describe RP6530, a novel PI3Kδ/γ inhibitor, in clinical development for HL and NHL. RP6530 exhibits anti-proliferative and cytotoxic activity both in vitro in HL cell lines and in vivo in HL xenograft mouse models. more...

(Submitter supplied) Rett syndrome is caused by mutations in the gene encoding methyl-CpG binding protein 2 (MECP2), an epigenetic regulator of mRNA transcription. Here we report a test of the hypothesis of shared pathophysiology of Rett syndrome and fragile X, another monogenic cause of autism and intellectual disability. In fragile X, the loss of the mRNA translational repressor FMRP leads to exaggerated protein synthesis downstream of metabotropic glutamate receptor 5 (mGluR5). more...

Analysis of KM-H2 Hodgkin lymphoma derived cells depleted for PTPN1. PTPN1 encodes PTP1B, a non-receptor-type member of the superfamily of protein tyrosine phosphatases. Results provide insight into the role of PTPN1 mutations in lymphomagenesis.

(Submitter supplied) The pathogenesis of classical Hodgkin lymphoma (cHL), the most common lymphoma in the young, is still enigmatic, largely because its Hodgkin and Reed-Sternberg (HRS) tumor cells are rare in the involved lymph node and therefore difficult to analyze. Here, by overcoming this technical challenge and performing for the first time a genome-wide transcriptional analysis of microdissected HRS cells in comparison to other B-cell lymphomas, cHL lines and normal B-cell subsets, we show that they differ extensively from the usually studied cHL cell lines, that the lost B-cell identity of cHLs is not linked to the acquisition of a plasma cell-like gene expression program, and that Epstein-Barr virus infection of HRS cells has a minor transcriptional influence on the established cHL clone. more...
