1 · What the graph read from it

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.

2 · The registry

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

backgroundMutations in the tumor suppressor gene von Hippel-Lindau (VHL) underlie a hereditary cancer syndrome-VHL disease-and are also frequently observed in sporadic renal cell carcinoma of the clear cell type (ccRCC). VHL disease is characterized by malignant and benign tumors in a few specific tissues, including ccRCC, hemangioblastoma and pheochromocytoma. The etiology of these tumors remains unresolved.

methodsConditional inactivation of the VHL gene in mouse (Vhlh) was generated to examine the pathophysiological role of the VHL gene function. Specific cell populations were isolated by fluorescence-activated cell sorting (FACS) and bone marrow transplants were performed to identify the Vhlh-inactivated cells responsible for the phenotype.

resultsPreviously we showed that inactivation of Vhlh in a subpopulation of kidney distal tubule cells resulted in hyperplastic clear-cell lesions and severe inflammation and fibrosis. Here, we show that this knockout mouse strain also develops Hif-2α-dependent vascular overgrowth (hemangioma) and extramedullary erythropoiesis in the liver. However, Vhlh inactivation was not detected in the liver parenchyma. We instead demonstrate that in these mice, Vhlh is inactivated in liver granulocytes and that hemangiomas are partially rescued in knockout mice reconstituted with wild-type hematopoietic stem cells, indicating the involvement of bone-marrow-derived leukocyte. Interestingly, bone marrow from knockout mice failed to generate the liver phenotype in wild-type recipients, suggesting that an additional cell type that is not derived from the bone marrow is involved in the development of the hemangioma phenotype.

conclusionThese results support the idea that the development of a full-blown VHL disease phenotype requires inactivation of the VHL gene not only in the tumor proper, but also in the stromal compartment.
