Morse Code Used by Human Cells? 281

Posted by samzenpus from the can-you-feel-them-talking dept.
Roland Piquepaille writes "Researchers from several universities and drug companies in the U.K. have discovered that our cells are using Morse-like signals to switch genes on and off. The Biotechnology and Biological Sciences Research Council (BBSRC) write that this discovery may have major implications for the pharmaceutical industry. Better and more efficient drugs would only deliver the signals to our cells that will activate a desired behavior. Sounds like science fiction? Read more for other details, references and pictures."

      In case anyone here is wondering, you can get the basic amateur radio license without having any knowledge of Morse code. You need the 5WPM morse code for the more advanced licenses that open up more frequencies and higher power, especially the HF ones.
      • Yeah, but where's the fun in doing only the bare minimum? I remember when 13 wpm was a reasonable expectation. But hey, you're losing out if you don't learn it. You can transmit and receive further and on less power with CW.

        Doesn't anyone like a challenge anymore? It is all about buying multi-thousand-dollar Japanese rigs, prefab antennas and high-power amps? Where's the fun in that? You might as well just get a mobile phone.

          Yes, CW is useful for weak signal work, and could theoretically be helpful in an emergency situation where nothing else was available (sending morse by tapping 2 wires together, etc...). But outside of the amateur service (and the occasional automated ID system), it simply isn't used anymore.

        It's known that nature uses reaction-diffusion techniques to generate camouflage patterns for animals [sjsu.edu]. This was noted by Alan Turing. It wouldn't be too surprising to see if this occurred inside cells as well. There's an interesting 3D demo to see what reaction-diffusion equations can do in real-time [markmark.net]. Perhaps the pharamceutical companies will have to figure out ways of generating such signalling patterns.

      There's nothing in that press release to convince me that a "major signaling pathway" has been discovered. There was just an overblown analogy; no science was explained.

      And maybe you think biology is "oversold" because you don't know anything about it. Does anybody in your family take a statin (for lowering cholesterol levels)? If so, you should know that amazingly little details have been worked out about why those drugs work, down to the proteins that sit on the endoplasmic reticulum that are involved in cholesterol metabolism regulation, and the enzymes that interact with them. We know how that regulatory pathway eventually trickles down to interaction with DNA via transcription factors.

    A Morse code for human cells

    Morse code is a simple, effective and clear method of communication and now scientists believe that cells in our body may also be using patterns of signals to switch genes on and off. The discovery may have major implications for the pharmaceutical industry as the signalling molecules that are targeted by drugs may have more than one purpose. The number of 'dots and dashes' being used by each signal could have different purposes, all of which could be modified by a drug.

    The researchers, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and working at the Universities of Liverpool and Manchester and the Royal Liverpool Children's Hospital, in collaboration with scientists at AstraZeneca and Pfizer, have studied transcription factors, the signalling molecules inside cells that activate or deactivate genes. They found that the strength of the signal is less important than the dynamic frequency pattern that is used.

    Professor Michael White of the Centre for Cell Imaging at Liverpool and leader of the research group said, "The timing of the repeating signal is essential for its interpretation. It seems that cells may read the oscillations in level of transcription factors in a similar way to Morse code."

    The researchers focused on the response of a transcription factor involved in controlling the crucial processes of cell division and cell death. They found that the dynamics of the signalling molecule resemble the changes in calcium levels that encode other messages in cells. The results suggest how common signalling molecules could convey different messages through different frequencies.

    Professor Douglas Kell, who sits on BBSRC Council and is a member of the research team, said, "This raises new challenges for drug designers. It appears that simply aiming to knock down signalling molecules with drugs, as many people are trying to do, may have weak or even undesirable effects as a range of signals could be cancelled out. It is going to be important in the future to decode the Morse-like messages from the molecules to make sure that only the desired effects are blocked."

    Professor Julia Goodfellow, BBSRC Chief Executive, said, "This research is an example of a multi-disciplinary approach producing vitally important results. By combining expertise in cell biology, chemistry, mathematical modelling and bio-imaging the research team have discovered this coded signal that is going to inform the development of better, more effective drugs."

    Notes to Editors

    This research features in the January 2005 issue of Business, the quarterly magazine of the Biotechnology and Biological Sciences Research Council.

    The researchers used cultured cells, which had been modified to carry fluorescent proteins or a gene for bioluminescence which enabled them to visualise events in the cell.

    The signalling molecule focused on was NF-kappa B which is a transcription factor involved in cell death and cell division.

    The collaborative research was conducted by scientists at the Universities of Manchester, Liverpool , The Royal Liverpool Children's Hospital and the pharmaceutical companies AstraZeneca and Pfizer.
