  6. 6. Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies  ScienceDaily (Feb. 7, 2011)
  7. 7. Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies   <ul><li>Alu RNA accumulates </li></ul><ul><li> in retina </li></ul><ul><li>It causes macular </li></ul><ul><li> degenaration </li></ul><ul><li>and death of retina </li></ul><ul><li>cells </li></ul>http://www.sciencedaily.com/releases/2011/02/110206132904.htm
  8. 8. Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies <ul><li> Accumulation </li></ul><ul><li>due to </li></ul><ul><li> decreased levels of </li></ul><ul><li>“ dicer” enzyme </li></ul><ul><li> which </li></ul><ul><li>Degradates Alu RNA </li></ul>
  9. 9. Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies <ul><li>Two Possible Solutions were proposed </li></ul><ul><li>Increase “dicer” Block Alu RNA </li></ul><ul><li>enzyme </li></ul>
  10. 10. Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies <ul><li>STUDENT OBSERVATION </li></ul><ul><li>  </li></ul><ul><li>I think that this discovery has not only a relevant implication in the physiopatology of the Geographic Atrophy, it is also important to develop a treatment to heel the condition and even more, to prevent it. This will give a hope to those patients with the illness or to those who are prone to it. </li></ul><ul><li>Moreover, this news shows us that is important to investigate about the RNA processing and how can it be related to pathologies. </li></ul><ul><li>  </li></ul>
  11. 11. Advance Could Speed Use of Genetic Material RNA in Nanotechnology ScienceDaily (Jan. 19, 2011)
  12. 12. Advance Could Speed Use of Genetic Material RNA in Nanotechnology <ul><li>A change in the sugar ring </li></ul><ul><li>of the RNA, averts the effect </li></ul><ul><li>of the enzyme RNAse in this </li></ul><ul><li>molecule, making the RNA </li></ul><ul><li>more stable </li></ul>Enzyme RNAse
  13. 13. Advance Could Speed Use of Genetic Material RNA in Nanotechnology <ul><li>The RNA stability was proved </li></ul><ul><li>introducing a nanomotor of </li></ul><ul><li>bacteriophague phi29 in a </li></ul><ul><li>bacteria </li></ul><ul><li>The nanomotor, based on </li></ul><ul><li>modified RNA didn´t got </li></ul><ul><li>degraded even in the </li></ul><ul><li>presence of RNAse </li></ul>
  14. 14. Advance Could Speed Use of Genetic Material RNA in Nanotechnology <ul><li> </li></ul><ul><li>This modified RNA is useful in </li></ul><ul><li>nanotechnology because it is </li></ul><ul><li>not easily degraded and it </li></ul><ul><li>can adopt a 3D structure. </li></ul><ul><li>This discovery can be useful </li></ul><ul><li>in the development of </li></ul><ul><li>treatments for cancer </li></ul>
  15. 15. Advance Could Speed Use of Genetic Material RNA in Nanotechnology <ul><li>STUDENT OBSERVATION </li></ul><ul><li>I think that it is amazing that just change in a molecule ( RNA ) can adapt it to be part of a nanostructure, and I think it is even more amazing that the modified RNA through this nanotechnology can be useful in sick people, like in cancer patients. </li></ul><ul><li>  I also think that this nanotechnology allows the development of a new less invasive therapies due to its small size. </li></ul><ul><li>  </li></ul>
  16. 16. MEDICAL UTILITY
  17. 17. MEDICAL UTILITY <ul><li>Age-Related Macular Degeneration: Key Mechanism in Geographic Atrophy Identified, Two Possible Therapies   </li></ul><ul><li>Patients who suffer from Geographic Atrophy can have a hope due to the therapies that can be developed based on this scientific advance. </li></ul>
  18. 18. MEDICAL UTILITY <ul><li>Advance Could Speed Use of Genetic Material RNA in Nanotechnology </li></ul><ul><li>With this nanotechnolgy,based on RNA, therapies for cancer can be developed. </li></ul>
  19. 19. MEDICAL UTILITY <ul><li>Both discoveries can be used in the development of a mechanism in which illnesses can be prevented, for example the Geographic Atrophy, Cancer or another. </li></ul><ul><li>That prevention will allow a better perspective to those patients prone to suffer that illnesses. </li></ul>
