Who in the world is Harold Varmus?

 :: Posted by American Biotechnologist on 08-27-2013

Harold Varmus is the 1989 Nobel Prize in Physiology or Medicine for discovery of the cellular origin of retroviral oncogenes. Check out a tribute to Dr. Varmus below.

A tribute to the creature of the summer!

As we prepare for our August camping vacations, the American Biotechnologist would like to pay tribute to everyone’s favorite summer annoyance. The ghastly mosquito. In this video, you will see biology at its best. If only I was able to cannulae a blood vessel as quickly and efficiently as this wonderous creature I would have finished my vascular biology experiments much quicker!

C. Elegans: The Elegant Teaching Tool

 :: Posted by American Biotechnologist on 05-29-2013

Teaching biology? Don’t forget about one of the most studied model organisms in biology, C. elegans.
And if you are planning on exploring C. elegans in the classroom, the C. elegans Behavior Kit allows students to work with and learn about C. elegans.

With this kit, students are able to:

  • Get hands-on experience with a model eukaryotic organism
  • Observe and study the life cycle of C. elegans
  • Utilize their microscope skills
  • Learn how to subculture
  • Learn about genetics and its effect on behavior
  • Discover the connection between learning, the daf-18 gene, and the AIY and ASE neurons

The “dark matter” of biology

 :: Posted by American Biotechnologist on 02-19-2013

Ramin Shiekhattar, from the Wistar Institute, hates the term “junk DNA.” He much prefers to call it the dark matter of biology.

Long segments of RNA—encoded in our DNA but not translated into protein—are key to physically manipulating DNA in order to activate certain genes. These non-coding RNA-activators (ncRNA-a) have a crucial role in turning genes on and off during early embryonic development, researchers say, and have also been connected with diseases, including some cancers, in adults.

In an online article of the journal Nature, a team of scientists led by Wistar’s Ramin Shiekhattar, Ph.D., detail the mechanism by which long non-coding RNA-activators promote gene expression. They show how these RNA molecules help proteins in the cell to create a loop of DNA in order to open up genes for transcription. Their experiments have also described how particular ncRNA-a molecules are related to FG syndrome, a genetic disease linked to severe neurological and physical deficits.
