Expression and significance of transforming growth factor-β receptor type II and DPC4/Smad4 in non-small cell lung cancer.
Article in Experimental and therapeutic medicine, 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
The aim of the present study was to investigate the expression levels of transforming growth factor-β (TGF-β) receptor type II (TβRII) and DPC4/Smad4 in the TGF-β signaling pathway and the importance of these expression levels in non-small cell lung cancer (NSCLC). The mRNA and protein expression levels of TβRII and DPC4/Smad4 were detected by reverse transcription-quantitative polymerase chain reaction and western blotting, respectively, in NSCLC and control nonlesional lung tissues of 60 patients. The protein expression levels of DPC4/Smad4 were detected by immunohistochemistry in paraffin-embedded samples of NSCLC. In addition, the correlations among the expression levels of TβRII and DPC4/Smad4 and their association with the clinical and pathological features of NSCLC were analyzed. The expression levels of TβRII and DPC4/Smad4 in NSCLC tissues were significantly lower when compared with the control nonlesional lung tissues (P<0.05). In addition, the expression of TβRII and DPC4/Smad4 in poorly-differentiated NSCLC tissues was significantly lower compared with moderately- or well-differentiated NSCLC tissues (P<0.05). The expression levels of TβRII and DPC4/Smad4 were significantly lower in NSCLC tissues with metastatic lymph nodes compared with tissue without metastatic lymph nodes (P<0.05). Thus, the expression levels were demonstrated to significantly correlate with the clinical and pathological stages, and subsequently were shown to be associated with the occurrence and progression of NSCLC. In conclusion, TβRII and DPC4/Smad4 may play an important role in the tumorigenesis, differentiation and progression of NSCLC via the TGF-β signaling pathway.
