Detection of human breast cancer cells using a 2-deoxy-D-glucose-functionalized superparamagnetic iron oxide nanoparticles.
Article in Cancer biomarkers : section A of Disease markers, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundBreast cancer is one of the most common type of female cancer worldwide and represents 14% of cancer-related deaths in women. Early detection is the most important factor for treatment and prognosis of breast cancer. In most countries, the women are currently screened with mammography only. Even though there has been considerable progress in the detection, surgical therapy, hormonal and target therapy of breast cancer, there are about ∼ 3500 000 women who die from breast cancer each year. Therefore, there is an urgent need to explore the new techniques for early detection of breast cancer. Magnetic resonance imaging (MRI) has the potential to improve breast cancer detection at an early stage because of its higher sensitivity. Glucose transporter (Glut) is a cellular transmembrane receptor that plays key roles in cell glucose metabolism and over-expressed in breast cancer cells. 2-deoxy-D-glucose having a similar structure to D-glucose can specifically interact with Glut.
methodsIn the present study, we constructed a 2-deoxy-D-glucose-functionalized superparamagnetic iron oxide (SPIO) nanoparticles that coated with meso-2,3-dimercaptosuccinic acid (γ-Fe2O3@DMSA-DG NPs). The aim of this study is to evaluate the efficacy of new constructed MRI contrast agent (γ-Fe2O3@DMSA-DG NPs) in detecting human breast cancers.
resultsOur results showed that breast cancer cells MDA-MD-231, MCF7 and ZR-75-1 had a high uptake rate of γ-Fe2O3@DMSA-DG NPs than human breast fibroblast cell HUM-CELL-0056. There was a significant difference of T2 relaxation times and signal intensity between breast cancer cells and human breast fibroblast cells labeled with γ-Fe2O3@DMSA-DG NPs when MIR.
conclusionOur results indicated that γ-Fe2O3@DMSA-DG NPs may be used as a new MRI contrast agent for detection of breast cancer.
