 | Retrovirus reverse transcripiton This is the best animation I've found for an introduction to the mechanism of reverse transcription. Although simplistic, the message is well defined (courtesy of HHMI). As this is my current area of research, I'll try to follow with retrotransposons (when I understand them better). 2009年03月30日再生回数 103796 |
 | Retrovirus Replication 3D Animation The example used is the HIV Lentivirus. This video does a great job describing "complex" retrovirus transcription in a visually appealing way that is sufficient in detail for upper level coursework and possibly graduate coursework. * Modes of action for some anti-viral drugs are also described. NOTE: The viral genome in the form of DNA stays in the cell's chromosome! This is the predominant reason for the persistence of retroviral infections. 2011年04月29日再生回数 67218 |

Retroviruses And Pseudogenes www.youtube.com --- RETROVIRUSES A retrovirus is an RNA virus that is replicated in a host cell via the enzyme reverse transcriptase to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. The virus itself stores its nucleic acid in the form of a +mRNA (including the 5'cap and 3'PolyA inside the virion) genome and serves as a means of delivery of that genome into cells it targets as an obligate ... 2010年06月04日再生回数 23653 |

 | Evolution: Genetic Evidence - Endogenous RetroVirus Evolution: Genetic Evidence - Ubiquitous Proteins Excerpt from The Cassiopeia Project; "Facts of Evolution". The Full series can be found at: www.cassiopeiaproject.com (Transcript of Video Below) A third type of structure found within the genome is also direct evidence of genetic relationships. Retroviruses like HTLV1 (which causes a type of leukemia) and AIDS make a DNA copy of their own viral genome and insert it into their host's genome. If this happens inside of sperm cells or egg cells the retroviral DNA will be inherited by descendants of the host. And these copies of virus DNA are called endogenous retroviruses. In human DNA, there are about 30000 endogenous retroviruses. There are at least seven distinct instances of identical retrogene insertions shared between chimps and humans. The phylogenic tree for cats provide another example. The standard phylogenetic tree has small cats diverging later than large cats. The small cats (eg the jungle cat, European wildcat, African wildcat, blackfooted cat, and domestic cat) share a specific retroviral gene insertion. In contrast, all other carnivores which diverged earlier lack this sequence. Retrovirus Example Let's examine how Endogenous RetroViruses or ERVs would behave within a model of evolution by common descent. Suppose an ancient creature, let's call it Primus Mammalius, is the common ancestor of all modern mammals and is infected by a retrovirus that becomes endogenous. All of the Primus descendants would be ... 2009年08月16日再生回数 10724 |

 | Retroviruses, Reproduction, and Regenerative Medicine: The Influence of Federal Funding Ann Anderson Kiessling, Ph.D. (Harvard Medical School and the Bedford Stem Cell Research Foundation, Bedford Massachusetts) was introduced by Dorrie Fontaine, Ph.D., RN, FAAN (Sadie Health Cabaniss Professor and Dean, School of Nursing, University of Virginia) who also described a newly established award by the School of Nursing, called the "Alumni Achievement Award," which is awarded to a nursing graduate who has contributed beyond the field of nursing. This first 2010 award was given to Dr. Kiessling by Dr. Fontaine and Pamela Booth Woodard (BSN, 1969, President of the School of Nursing Alumni Association). Dr. Kiessling addressed the role of federal funding in biomedical research with an example from her area of study, retroviruses and parthenotes. Her lecture also included the role of federal funding in the 1971 discovery of the Rous Sarcoma Virus and cancer pathogenesis and recent stem cell debates and resulting legislation from the Clinton and Obama administrations.
