Metallothionein gene expression in renal cell carcinoma.
Article in Indian journal of urology : IJU : journal of the Urological Society of India, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionMetallothioneins (MTs) are a group of low-molecular weight, cysteine-rich proteins. In general, MT is known to modulate three fundamental processes: (1) the release of gaseous mediators such as hydroxyl radical or nitric oxide, (2) apoptosis and (3) the binding and exchange of heavy metals such as zinc, cadmium or copper. Previous studies have shown a positive correlation between the expression of MT with invasion, metastasis and poor prognosis in various cancers. Most of the previous studies primarily used immunohistochemistry to analyze localization of MT in renal cell carcinoma (RCC). No information is available on the gene expression of MT2A isoform in different types and grades of RCC. MATERIALS AND
methodsIn the present study, total RNA was isolated from 38 histopathologically confirmed cases of RCC of different types and grades. Corresponding adjacent normal renal parenchyma was taken as control. Real-time polymerase chain reaction (RT PCR) analysis was done for the MT2A gene expression using β-actin as an internal control. All statistical calculations were performed using SPSS software.
resultsThe MT2A gene expression was found to be significantly increased (P < 0.01) in clear cell RCC in comparison with the adjacent normal renal parenchyma. The expression of MT2A was two to three-fold higher in sarcomatoid RCC, whereas there was no change in papillary and collecting duct RCC. MT2A gene expression was significantly higher in lower grade (grades I and II, P < 0.05), while no change was observed in high-grade tumor (grade III and IV) in comparison to adjacent normal renal tissue.
conclusionThe first report of the expression of MT2A in different types and grades of RCC and also these data further support the role of MT2A in tumorigenesis.
