Expression of lysophosphatidic acid receptors and local invasiveness and metastasis in Chinese pancreatic cancers.

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
BACKGROUND AND
objectivesThe present study evaluated the potential role of lysophosphatidic acid receptors (lpars) in processes leading to local invasiveness and metastasis in Chinese pancreatic carcinoma.
methodsReal-time reverse-transcriptase polymerase chain reaction and Western blot analysis were used to detect expression of lpars in tumour and adjacent non-tumour tissues from patients with surgically resected pancreatic carcinoma. Surgical specimens from 50 patients were examined for relative expression of each receptor's messenger rna (mrna) and protein. Findings were analyzed for correlations with tumour size, pathologic classification, clinical stage, and infiltration of capsule and lymphonodi.
resultsIncreased levels of mrna of lpars (lpar1 ≈ lpar3 < lpar2) were found in the pancreatic cancer tissues examined. Low levels of transcripts for lpar1, lpar2, and lpar3 receptors were detectable in adjacent non-tumour tissues. The difference in lpar1 protein expression between tumour and adjacent non-tumour tissues does not seem significant, but the signals of lpar2 expression in pancreatic cancer tumour tissues were significantly amplified compared with those in adjacent non-tumour tissues. Tumour and adjacent non-tumour tissues both weakly expressed lpar3 protein with no statistical difference. However, expression of lpar1, lpar2, and lpar3 showed an obvious correlation with infiltration of capsule cells, surrounding lymphonodi, and specific histopathologic features.
conclusionsLysophosphatidic acid receptor is a promising indicator for pancreatic cancer, and our findings suggested that lpar2 might be a potential target for clinical treatment of pancreatic cancer.
