Expression of tumour transcription factor GLI1 in canine mammary tumours tissue.

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
backgroundMammary tumor is one of the most common diseases of canine in pet clinics.
objectivesThis study investigates the distribution and expression of the tumor transcription factor GLI1 and the downstream proteins, Bmi1 and Sox2, in canine mammary tumors and paracancerous tissues.
methodsCancerous and paracancerous normal mammary tissues were detected using western blotting (WB), and immunohistochemistry.
resultsThe results showed that the histopathology of different types in mammary tumors by microscopic observation. GLI1/Bmi1/Sox2 expression was significantly higher in canine mammary invasive carcinoma than in ductal carcinoma and adjacent normal mammary tissues (p < 0.01). The expression of GLI1 in invasive carcinoma tissues was significantly higher than Bmi1 and Sox2, while Sox2 expression in ductal carcinoma tissues was significantly higher than GLI1 and Bmi1 (p < 0.01). GLI1/Bmi1/Sox2 all showed positive reactions in both mammary tumor and adjacent normal mammary tissues with immunohistochemistry. GLI1 and Sox2 showed strong positive staining in the cytoplasm of invasive mammary carcinoma and ductal carcinoma cells, and weak positive staining in the nuclei. The positive Bmi1 reaction was mainly concentrated in the cytoplasm of invasive carcinoma and ductal carcinoma cells, while the positive reaction on the cell membrane was weak.
conclusionsWe speculate that GLI1 and related proteins play an important role in regulating the proliferation and differentiation of tumors. Therefore, it provides important reference for the pathogenesis and pathogenicity of canine mammary tumor.
