Developmental genes often take inputs from two independent sources Albert Erives, associate professor in the University of Iowa Department of Biology, and his graduate student, Justin Crocker, currently a postdoctoral researcher at the Howard Hughes Medical Institute (HHMI) Janelia Farm Research Campus, have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent “morphogen concentration...

Retinoic Acid Gradient Observed For The First Time In A Zebrafish Embryo

RIKEN In a ground-breaking study, researchers from the RIKEN Brain Science Institute in Japan report a new technique that allows them to visualize the distribution of retinoic acid in a live zebrafish embryo, in real-time. This technique enabled them to observe two concentration gradients going in opposing directions along the head-to-tail axis of the embryo, thus providing long-awaited evidence that retinoic acid is a morphogen. The report, published today in the journal Nature, puts...

How The Fruit Fly Got Its Wings
2013-03-12 16:16:04

The Ohio State University Scientists have delved deeper into the evolutionary history of the fruit fly than ever before to reveal the genetic activity that led to the development of wings — a key to the insect´s ability to survive. The wings themselves are common research models for this and other species´ appendages. But until now, scientists did not know how the fruit fly, Drosophila melanogaster, first sprouted tiny buds that became flat wings. A cluster of only 20...

New York University biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body plans. The researchers investigated a specific theory–morphogen theory, which posits that proteins controlling traits are arranged as gradients, with different amounts of proteins activating genes to create specified physical features. This theory was first put forth...

Evidence Discovered To Support Turing's Morphogen Theory

A team of UK researchers claims to have put forth the first ever experimental evidence in support of a long-standing theory about how biological patterns such as a leopard's spots or a tiger's stripes are formed. The study was the work of experts from King's College London, and according to a February 19 press release from the school, "The findings provide evidence to support a theory first suggested in the 1950s by famous code-breaker and mathematician Alan Turing," who championed the...

A new study has shed light on the process by which fruit flies develop with their body proportions remaining constant. The study, conducted by the research group of Professor Markus Affolter at the Biozentrum of the University of Basel and Sven Bergmann's group at the Department of Medical Genetics, University of Lausanne, has demonstrated that the morphogen Dpp and the feedback regulator Pentagone are key factors responsible for proportional tissue growth in wings of a fruit fly. This...

Salk scientists discover a highly conserved mechanism governing brain development If you think today's political rhetoric is overheated, imagine what goes on inside a vertebrate embryo. There, two armies whose agendas are poles apart, engage in a battle with consequences much more dire than whether the economy will recover---- they are battling for whether you (or frogs or chickens) will have a forebrain. In a study published in the August 19 online edition of Genes & Development,...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
