Chris Astill-Smith: Genetic Disorders, Epigenetics, Biology and the Emotions
This is a 10 minute extract from Chris Astill-Smith #39;s latest seminar. Genetic Disorders, Epigenetics, Biology and the Emotions. The 6 hour presentation looks first of all at the 5 major problems which Chris experiences in his Clinic. Chris Astill-Smith DO DIBAK is a Registered Osteopath graduating from the British School of Osteopathy 1970. Lecturer in Nutrition and Dietetics at the British School of Osteopathy 1973-80 and in Arthrology and Myology 1981-89. He obtained his Diplomate from the International College of Applied Kinesiology 1988 and lectures internationally on Functional Biochemistry most weekends. Awarded Assistant Professor status at the Institute for Manual Medicine, Russia 1992. Chris calls upon 41 years of experience of clinical management and will share with you his extensive knowledge in the subject as well as a multitude of clinical pearls. In 1992 Chris founded Metabolics Ltd In 2011 Chris and his partners founded Epigentics Ltd http://www.epigenetics-international.comFrom:Clive BinghamViews:1 0ratingsTime:09:56More inEducation

ScienceDaily (Nov. 2, 2012) A new mechanism in the formation of ribosomes has been discovered by researchers from the Heidelberg University Biochemistry Center. In an interdisciplinary approach, the Heidelberg scientists, along with colleagues from Switzerland and Japan, describe a heretofore uncharacterised protein that plays a specific role in ribosome assembly in eukaryotes, organisms whose cells contain a cell nucleus. This protein makes sure that specific factors required for ribosome synthesis are transported together, like hitchhikers, into the nucleus to the site of assembly.

The results of this research were published in Science.

Ribosomes, the protein factories of the cell, are macromolecular complexes of ribonucleic acids (RNA) and ribosomal proteins (r-proteins) that are organised in a highly complicated three-dimensional nanostructure. Correct synthesis of ribosomes is critical for the division of all cells and is a process that follows strict rules. In eukaryotes, new ribosomes are formed predominantly in the cell nucleus. Therefore, the r-proteins needed for ribosome formation must travel from the cytoplasm of the cell to a site in the nucleus where the ribosomes are assembled. Until recently it was not clear whether r-proteins that have a similar function and form functional clusters on the ribosome structure are also co-transported into the nucleus.

The researchers have now found a protein that coordinates the co-transport of certain r-proteins in functional clusters into the cell nucleus. This factor is called Symportin1, for synchronised import. "Symportin1 synchronises the import of both the Rpl5 and Rpl11 r-proteins into the cell nucleus and supports their integration into the growing ribosome structure," explains Prof. Dr. Irmgard Sinning of the Heidelberg University Biochemistry Center (BZH). "It employs a familiar logistical concept from every day life, like picking up a hitchhiker or sharing a taxi with someone headed for the same destination," says Dr. Gert Bange of the BZH, lead author of the study together with Dr. Dieter Kressler (now of Fribourg University).

The researchers from Heidelberg University and the University of Fribourg (Switzerland) collaborated closely with colleagues from Osaka University in Japan on the research. "The combination of different methods ranging from traditional cell biology to new biophysical approaches was crucial in developing the detailed picture of this previously unknown biological mechanism," emphasises Prof. Dr. Ed Hurt, also of the BZH. The study took advantage of the Biochemistry Center's crystallisation platform and the research received support from the Cluster of Excellence "CellNetworks" of Heidelberg University.
