World's first successful visualisation of key coenzyme

16.04.2014

Japanese researchers have successfully developed the world's first imaging method for visualising the behaviour of nicotine-adenine dinucleotide derivative (NAD(P)H), a key coenzyme, inside cells. This feat could ultimately facilitate the diagnosis of cancer and liver dysfunction and help to elucidate the mechanisms of neurological disorders.  

A Japanese research team led by Drs. Hirokazu Komatsu and Katsuhiko Ariga of the International Center for Materials Nanoarchitectonics, in collaboration with Professors Yutaka Shido and Kotaro Oka of Keio University, have developed the world's first method for visualising the coenzyme nicotine-adenine dinucleotide derivative (NAD(P)H) inside cells.

Fluorescent imaging – used to identify and visualise cellular components by attaching a fluorescent substance – is an effective method for exploring vital phenomena.

Until now, however, the development of a method for visualising NAD(P)H, which plays a key role in various vital phenomena and diseases, has proven elusive due to the low reactivity of NAD(P)H to fluorescent substances.

The research group succeeded in developing a new fluorescent probe that specifically reacts with NAD(P)H, and achieved fluorescent imaging of NAD(P)H for the first time in the world, through the combined use of the new probe and an artificial promoter capable of promoting reactivity.

The new NADH imaging method could be used for various purposes, including: promoting early detection and supporting cancer treatment by detecting NADH leakage from invasive cancers; diagnosing liver dysfunction by detecting excessive NADH caused by cirrhosis of the liver; and elucidating the lack of NADH in patients with brain or neurological diseases such as Alzheimer's Disease, depression, and Parkinson's Disease.

The new method will also prove of great value in other life sciences research.

The research results will be published in a German scientific journal, Angewandte Chemie International Edition.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
