IRCM researchers discover a nerve cell´s internal clock A team of IRCM researchers, led by Dr. Frédéric Charron, recently uncovered a nerve cell´s internal clock, used during embryonic development. The discovery was made in collaboration with Dr. Alyson Fournier´s laboratory at the Montreal Neurological Institute. Published today in the prestigious scientific journal Neuron, this breakthrough could lead to the development of new tools to repair and...

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...

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,...

New research may help to explain why the location of postnatal neural stem cells in the brain determines the type of new neurons that are generated. The research, published by Cell Press in the July 28 issue of the journal Neuron, demonstrates that a signaling pathway which plays a key role in development also actively regulates the fate of neural stem cells in the adult brain. Manipulation of this signaling pathway redirected the fate of adult stem cells, a finding that may impact the design...

Common genetic recipes pattern organs as different as shark gills and human hands A SCUBA expedition in Australia and New Zealand to find the rare embryos of an unusual shark cousin enabled American and British researchers to confirm new developmental similarities between fish and mammals. Elephant fish, a relative of sharks, utilize the same genetic process for forming skeletal gill covers that lizards and mammals use to form fingers and toes, researchers at the University of Chicago and the...

Sonic hedgehog, a gene that plays a crucial rule in the positioning and growth of limbs, fingers and toes, has been confirmed in an unexpected place in the embryos of developing mice "” the layer of cells that creates the skin. Named for a video game character, Sonic hedgehog describes both a gene and the protein it produces in the body. Its study is important to increase understanding of human birth defects. It was thought to be exclusively present in the cell layer that builds bone...

The laboratory of Dr. Fr©d©ric Charron, in Montreal, made this discovery The laboratory of Dr. Fr©d©ric Charron, a researcher at the Institut de recherches cliniques de Montr©al (IRCM), has discovered a new molecular mechanism that permits the guidance of visual nerves towards the brain. Their findings have been published in the current issue of the Journal of Neuroscience. The research was conducted in collaboration with Dr. Tomomi Shimogori from the RIKEN Brain...

In a study published in the journal Development, investigators at the USC School of Dentistry describe how to non-surgically reverse the onset of cleft palate in fetal mice - potentially one step in the journey to a better understanding of similar defects in humans. Yang Chai, the study's principal investigator and director of the School of Dentistry's Center for Craniofacial Molecular Biology, said that cleft palate is one of the most common congenital birth defects in humans and that...

The research group of Dr. Fr©d©ric Charron, a researcher at the Institut de recherches cliniques de Montr©al (IRCM), has made a discovery which could help treat spinal cord injuries and neurodegenerative diseases. This new finding has been published in the current issue of the prestigious scientific journal Neuron. Patricia T. Yam, S©bastien D. Langlois and Steves Morin, all at the IRCM, are listed as co-authors.The brain is composed of billions of interconnected neurons....

U.S. researchers said brain tumors appear to more aggressive when they feed off cancer stem cells that use Sonic Hedgehog protein signaling mechanisms. The researchers said the finding could help in the development of treatments that kill malignant brain tumors at their source and prevent them from recurring, Cedars-Sinai Medical Center said Monday. The study, conducted by Cedars Sinai's Maxine Dunitz Neurosurgical Institute, identified a subset of brain tumor stem cells that are...
