Effect of CD133 overexpression on bone metastasis in prostate cancer cell line LNCaP.
Article in Oncology letters, 2019. 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
Prostate cancer (PC) metastasizes to the bone, and a small number of cancer cells, described as cancer stem cells (CSCs), have the ability to differentiate into tumor cells. CSCs are responsible for tumor recurrence and metastases. In the present study, we examined whether ectopic overexpression of CD133, a key molecule maintaining the stability of CSCs in the human PC cell line, LnCaP, caused bone metastasis in a mouse model. Ectopic overexpression of CD133 was induced in LnCaP cells, and CSC-related protein expression was measured. Furthermore, a colony-forming assay was performed to compare results against the blank green fluorescent protein-expressing cells. Furthermore, epithelial to mesenchymal transition-related protein expression, cell migration and wound healing were investigated. To assess the role of CD133 in bone metastasis, CD133-overexpressing LnCaP cells were inoculated into mice via intracardiac injection, and bone metastasis was assessed via histological and immunohistochemical study. In addition, cytokine arrays were used to determine the cytokines involved in bone metastasis. Ectopic overexpression of CD133 in LnCaP cells increased CSC properties such as Oct-4 and Nanog expression and colony-forming ability. Furthermore, epithelial-to-mesenchymal transition (EMT) properties, including decreased E-cadherin and increased vimentin expression, wound gap distance, and cell migration increased. CD133 overexpression led to formation of bone metastatic tumors in mice, consistent with results of hematoxylin and eosin staining. In addition, an increase in expression of the macrophage-migration inhibitory factor was observed at the tumor margin in mice inoculated with CD133
