A Critical Role of Growth Arrest-Specific Gene 6-Mer Axis in the Pathogenesis of Endothelial Damage Contributing to Thrombotic Microangiopathy Associated with Graft-Versus-Host Disease after Allogeneic Hematopoietic Stem Cell Transplantation
Graft-versus-host disease (GVHD) and thrombotic microangiopathy (TMA) are severe complications of allogeneic hematopoietic stem cell transplantation (allo-SCT). Host endothelial cells are targets of alloreactive donor cytotoxic T lymphocytes or various proinflammatory cytokines following allo-SCT, and endothelial damage plays an important role in the pathogenic mechanism(s) of TMA associated with GVHD. However, the detailed mechanism(s) of TMA as well as GVHD have not yet been fully elucidated. Growth arrest-specific (Gas) 6 structurally belongs to the family of plasma vitamin K-dependent proteins working as a cofactor for...

Identifying a Murine Xenograft Model Relevant to Light-Chain Specific Approaches to Human Ig Light-Chain Diseases
CONCLUSIONS: The ALMC-1, RPMI 8226 and H929 IP models did not meet the criteria we required in order to effectively test specific interventions on circulating LC (Table 1). The NSG JJN3 IP model had a short latency period for LC, β2M and FLUX measurements, and had significant correlations among these measurements. The NSG JJN3 model met our criteria. We are currently evaluating soluble BCMA levels in this model also, These measurements will allow investigators to distinguish the impact of interventions on LC specifically, independent of tumor cells. We have used this model successfully to test an RNAi approach to redu...
