Alteration of ASIC1 expression in clear cell renal cell carcinoma.
Article in OncoTargets and therapy, 2015. 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
backgroundAcidic extracellular pH is a major feature of tumor tissue. Acid-sensing ion channels (ASICs) represent an H(+)-gated subgroup of the degenerin/epithelial Na(+) channel family and are activated by acidic microenvironment. Little is known about the expression and clinical significance of ASICs in solid tumors. The purpose of this study was to examine the expression of ASIC1 in human clear cell renal cell carcinoma (CCRCC) and to determine if the expression of ASIC1 is associated with clinicopathological features.
methodsThe expression of ASIC1 in CCRCC tissues at the mRNA and protein levels was determined by real-time quantitative polymerase chain reaction and Western blot analysis, respectively. A tissue microarray was used to assess the expression of ASIC1 protein in tumor tissue and matched adjacent normal tissues from 75 patients with CCRCC.
resultsASIC1 expression was detected in normal renal and CCRCC samples. The expressions of ASIC1 protein and mRNA were significantly decreased in the CCRCC tissues compared with matched normal renal tissues (P<0.05). The staining density measurement showed that the expression of ASIC1 was significantly decreased in stage I (P=0.037), stage II (P=0.026), and stage III (P=0.026), grades I-II CCRCC (P=0.004), and CCRCC from male patients (P=0.00002). However, no significant difference was observed for ASIC1 expression between CCRCC and normal tissue in patients with stage IV CCRCC (P=0.236), patients with grades III-IV CCRCC (P=0.314), and female patients (P=0.095). Spearman correlations demonstrated that ASIC1 expression did not correlate to tumor stage (correlation coefficient [CC =0.168], P=0.149) and the age of patients (CC -0.147, P=0.688) but showed a positive correlation to higher tumor grades (CC =0.270, P=0.018).
conclusionASIC1 is downregulated in CCRCC. ASIC1 expression may be potentially used as a novel biomarker and even a CCRCC therapeutic target. Further efforts will be made to clarify the mechanism of ASIC1 in occurrence, progression, and metastasis of CCRCC.
