Welcome to the SIROCCO Project

RNA silencing is a natural mechanism of gene regulation in cells. Small double-stranded RNA molecules 20-28 nucleotides long trigger the degradation of target RNA or DNA, thereby reducing specific gene expression. There is the potential to create small regulatory RNAs (siRNAs) that can be introduced into cells and silence genes that cause diseases.

The goals of the SIROCCO project are

  1. to exploit RNA silencing mechanisms in order to improve human and plant health
  2. to reveal how siRNAs play a role in developmental biology and disease defense
  3. to provide fundamental insights into the genetic networks that underlie normal and diseased embryonic development and adult growth

Project Announcements

Next SIROCCO Annual Meeting 11-13 October 2010 Heidelberg

This year’s SIROCCO Annual Meeting will take place at the EMBL Advanced Training Centre in Heidelberg 11-13 October 2010

Registration by email to Aileen Hogan fah37@cam.ac.uk by 18 July.

The SIROCCO AGM will precede the EMBO/EMBL Symposium ‘The Non-Coding Genome’ 13-16 October (Elisa Izaurralde, organizer). To register for this please visit:

A detailed description of our research program can be found on our About Page.

Partners have access to a Private Partners page including discounts and reporting documents.

There is also a Data and Bioinformatics site available which aggregates the various bioinformatic and resources developed and hosted by the SIROCCO consortium.
