B7 homolog 3 induces lung metastasis of breast cancer through Raf/MEK/ERK axis.
Article in Breast cancer research and treatment, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
purposeThe essential action of B7 homolog 3 (B7-H3) in different diseases and cancers has been documented. We here focused on its role in breast cancer through the Raf/MEK/ERK axis regarding lung metastasis.
methodsExpression pattern of B7-H3 was determined in breast cancer tissues and cells with its correlation with prognosis analyzed. Then, through transfection of lentivirus vector expressing B7-H3-shRNA, overexpression vector of B7-H3 (B7-H3-LV), U0126 (small molecule inhibitor of MEK), or PD98059 (small molecule inhibitor of ERK), the in vitro and in vivo effects of B7-H3 in breast cancer cell biological processes, and lung metastasis were analyzed in relation to the Raf/MEK/ERK axis.
resultsWe discovered elevated B7-H3 in breast cancer and its elevation associated with poor prognosis. B7-H3 promoted the malignant properties of breast cancer cells, accompanied with increased N-cadherin and vimentin and reduced E-cadherin. Additionally, overexpression of B7-H3 accelerated the lung metastasis in breast cancer in vivo. All the above promoting action of B7-H3 was achieved through activation of the Raf/MEK/ERK signaling pathway.
conclusionTaken together, B7-H3 can promote lung metastasis in breast cancer through activation of the Raf/MEK/ERK axis.
