Researchers at the Bellvitge Biomedical Research Institute (IDIBELL) and The Institute of Photonic Sciences (ICFO) have collaborated on the development of a diagnostic tool that identifies the metastatic ability of breast cancer cells.
The analysis is based on the characterization of the lipid component of the cells, which is indicative of malignancy. This has allowed the researchers to develop a classifier to discriminate cells capable of inducing metastasis. The results of the study have been published in the online version of the scientific journal PLoS ONE.
The characterization of the lipids associated with malignancy has been possible thanks to the technological development of a spectroscopic device named Raman along with the versatility offered by the experimental models of breast cancer. The results of this process form the basis for introducing this technique in routine cytological diagnosis, which could be extended in the future to diagnose other tumours.
The researchers have analyzed the main components and, partly, the less discriminating ones to assess the profile of the lipid composition of breast cancer cells. They have generated a classification model that segregated metastatic and non-metastatic cells. "The algorithm for the discrimination of the metastatic ability is a first step towards the stratification of breast cancer cells using this quick and reactive tool", explains the study coordinator, Àngels Sierra, researcher at the Biological Clues of the Invasive and Metastatic Phenotype group of IDIBELL.
Using cytology techniques, the researchers have found a correlation between the activation of lipogenesis (the chemical reaction leading to fatty acids in an organism) and the amount of saturated fats in metastatic cells indicating a worse prognosis and a decreased survival. The lipid content of the breast cancer cells might be a useful measure to determine various functions coupled to the progression of breast cancer. The work has been supported by the Instituto de Salud Carlos III, the former Spanish Ministry of Science and Innovation and the private Cellex Barcelona Foundation.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
