UAB research could improve the prognosis and treatment of lung cancer

08.01.2008
A group of scientists led by Professor Xavier Parés of the Department of Biochemistry and Molecular Biology at Universitat Autònoma de Barcelona, has published a research on AKR1B10, an enzyme that is detected in large quantities only in lung cancers, particularly those caused by smoking.

This enzyme can appear even when the cancer has not yet developed and lesions are precancerous. Thus this molecule would serve as a good marker in the diagnosis and prognosis of the disease. Moreover, its activity could play a relevant role in the development of lung cancer, which makes the research of great interest for potential future therapeutical applications as well.

According to researchers, both the experiments using test tubes and cell cultures revealed that the enzyme lowers the levels of the most active form of vitamin A (retinoic acid), a strong anticancerous agent. This is achieved by its strong retinal reductase activity, which favours chemical reduction transformation, thus causing retinal, the precursor of retinoic acid, to transform into its least active form, retinol.

Retinoic acid is present in several biological processes - from fetus development to cell proliferation and differentiation - by controlling the expression of certain genes. The reduction of this acid within cells, which is precisely the effect produced by the enzyme under study, is linked directly to the lack of cell differentiation and therefore favours the development of the cancer. In order to discover why the enzyme acts this way, scientists obtained and studied its three-dimensional structure and located the elements responsible for its role in the onset of cancer among smokers. The identification of these structural elements makes it possible to create a specific design for drugs that can treat this disease. In fact, researchers were able to observe how the substance tolrestat, used as an inhibitor of the enzyme AKR1B1, or aldose reductase, responsible for many secondary complications of diabetes, also worked to inhibit the activity of the enzyme AKR1B10. Since both enzymes contain similar structures, research was carried out on its possible applications in the treatment of diabetes.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
