The long and the short of it: Expanding small RNA biology in mammals

12.06.2006
In independent studies, Drs. Haifan Lin (Duke University) and Toshiaki Watanabe (Kyoto University) and colleagues report on their identification of novel small RNAs in the mouse germline.

"The discovery of piRNAs reveals a new dimension of the small RNA world. The complexity of piRNAs and their correspondence to different types genomic sequences implicates their potentially diverse functions. This is another gold mine for studying gene regulation, especially that related to reproduction and inheritance," explains Dr. Lin.

Their papers will be available online (www.genesdev.org) ahead of the scheduled July 1st publication date.

While hundreds of small RNAs have been isolated from somatic tissues in mammals, these papers are representative of a number of recent and up-and-coming studies independently identifying unique small RNAs residing in the mouse germline. The newly identified piRNAs are bigger in size (26-31 nucleotides long) than most previously described small RNAs in mammals, and are shown to be associated with the piwi subfamily of the Argonaute protein family. They are largely expressed in the mouse testes, and are thought to play a role in spermatogenesis.

Future research will be aimed at elucidating the pathway of biogenesis of these novel, small RNAs, as well as the targets and function of this emerging class of molecules. Dr.Watanabe emphasizes that "Newly identified small RNAs have features clearly different from those of previously identified small RNAs such as miRNAs or siRNAs. The sequences of this novel small RNAs are not conserved between species. However, interestingly, the presence of this novel class of small RNAs is conserved among diverse animals including humans."

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Research icebreaker Polarstern begins the Antarctic season

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Coping with errors in the quantum age

Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
