Bortezomib inhibits the survival and proliferation of bone marrow stromal cells.
Article in Blood research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBortezomib is widely used for the treatment of multiple myeloma. Bone marrow stromal cells (BMSCs) endow myeloma cells with survival and growth advantages. However, the influence of bortezomib on BMSCs is not well elucidated. We examined the effects of bortezomib on the survival and growth of BMSCs in vitro.
methodsThe effects of bortezomib on the survival and proliferation of the BMSC MS-5 cell line and on BMSCs obtained from healthy individuals (N=4) and newly diagnosed myeloma patients (N=5) were investigated in vitro. Transmembrane cell migration was evaluated using the Transwell system. A short interfering RNA strategy was used to knock down the expression of chemokine (CXC motif) ligand 12 (CXCL12) mRNA. To examine the effects of bortezomib-exposed BMSCs on the migration and localization of myeloma cells, MS-5 monolayers were treated with bortezomib for 24 hr, washed, and then overlaid with human RPMI8226 myeloma cells.
resultsBortezomib inhibited BMSC proliferation in a concentration-dependent manner, and induced cellular apoptosis. Bortezomib decreased CXCL12 production by BMSCs. Knockdown of CXCL12 mRNA in BMSCs revealed that CXCL12 served as an autocrine growth factor. Short-term bortezomib treatment of BMSC monolayers reduced the tendency of myeloma cells to locate to positions under the monolayers.
conclusionBortezomib inhibits the survival and growth of BMSCs via downregulation of CXCL12, which may contribute to the clinical effects of this agent.
