A novel protein is lower expressed in renal cell carcinoma.
Article in International journal of molecular sciences, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Engrailed-2 (EN2) has been identified as a candidate oncogene in breast cancer and prostate cancer. It is usually recognized as a mainly nuclear staining in the cells. However, recent studies showed a cytoplasmic staining occurred in prostate cancer, bladder cancer and clear cell renal cell carcinoma. The inconsistency makes us confused. To clarify the localization and expression of EN2 in renal cell carcinoma, anti-EN2 antibody (ab28731) and anti-EN2 antibody (MAB2600) were used for immunohistochemistry (IHC) respectively. Interestingly, we found that EN2 detected by ab28731 was mainly presented in cytoplasm while EN2 detected by MAB2600 was mainly presented in nucleus. To further investigate the different patterns observed above, lysates from full-length EN2 over expression in HEK293T cells were used to identify which antibody the EN2 molecule bound by western blot. Results showed ab28731 did not react with the lysates. For this reason, the novel specific protein detected by ab28731 was not the EN2 molecule and was named nonEN2. Then using the renal carcinoma tissue microarray and renal tissues, we found that the protein expression levels of nonEN2 in kidney tumor tissues was significantly lower than that in kidney normal tissues (p < 0.05), so was in renal cell lines. Taken together, nonEN2 is lower expressed and may play an important role in renal cell carcinoma.
