Project description:To determine combination effect of GSK126 and pomalidomide at the RNA levels in EZH2 Y641 mutant DLBCL, We performed gene expression profiling in WSU-DLCL2 cell line after co-treatment of GSK126 and pomalidomide
Project description:Single cell RNA-seq analysis for spleen tissue isolated from mice under steady state, and subjected to phenohydrazine (PHZ) and bleeding treatment respectively. Single cell RNA-seq analysis for bone marrow cells isolated from mice under steady state.
Project description:This SuperSeries is composed of the following subset Series: GSE31421: Cereblon expression is required for the anti-myeloma activity of lenalidomide and pomalidomide [expression profiling] GSE31451: Cereblon expression is required for the anti-myeloma activity of lenalidomide and pomalidomide [aCGH] Refer to individual Series
Project description:Blood from 17 patients taking enteric-coated low-dose aspirin (LDA) and with suspected bleeding from small intestine and 18 control patients taking aspirin were analyzed. Results provide insight into the risk for aspirin-induced small bowel bleeding.
Project description:BACKGROUND Antithrombotic medications target coagulation factors. Their use is associated with an increased bleeding risk. Safer drugs are needed. We described that the heat shock protein 70 (Hsp70) exhibits antithrombotic properties that do not influence bleeding. OBJECTIVES By using murine models, we want to test the hypothesis that overexpressing Hsp70 with CM-695, a dual inhibitor of HDAC6 and phosphodiesterase 9, protects against thrombosis while leaves bleeding tendency unaltered. METHODS CM-695 was used to induce Hsp70 overexpression. Hsp70 overexpressing mice were submitted to three thrombosis-triggering procedures. The ferric chloride carotid artery model was used to compare the antithrombotic role of CM-695 and rivaroxaban, a direct oral anticoagulant. The mouse tail transection model was used to compare the bleeding tendency upon CM-695 or rivaroxaban administration. RESULTS Intraperitoneal (i.p.) 20 mg/kg CM-695 increased Hsp70 expression markedly in the murine aortic tissue. This treatment delayed thrombosis in the collagen/epinephrine [P=0.04 (Log-Rank test), n=10], Rose Bengal/laser [median vessel occlusion time (OT): 58.6 vs. 39.0 minutes (min) in the control group (CG), P=0.008, n≥10] and ferric chloride (OT: 14.7 vs. 9.2 min in the CG, P=0.032, n≥10) models. I.p. 80 mg/kg CM-695 (n≥9) and intravenous 3 mg/kg rivaroxaban (n≥8) significantly delayed thrombosis. CM-695 did not induce bleeding [median bleeding time (BT): 8.5 vs. 7.5 min in the CG, n≥10]. However, this was dramatically increased by rivaroxaban (BT: 30.0 vs. 13.7 min in the CG, P=0.001, n=10). CONCLUSIONS CM-695 is a new antithrombotic drug devoid of bleeding risk that may be envisioned as a useful clinical tool.
