Developmental biology. From genetic association to genetic switch.
at which nucleation occurs is determined largely by the size of the nanodroplets present (10). Could the precritical clusters observed by Gebauer et al. also be the result of stabilization of calcium carbonate clusters by another species present as an impurity? This mechanism would provide a basis for stabilizing precritical clusters in a free-energy minimum and does not contradict classical nu...
متن کاملHitting the genetic off switch.
I n 1996 Worth magazine proclaimed that Isis Pharmaceuticals could become the next Microsoft, a prediction that turned out to be a particularly egregious example of hyperbole run amok. To be sure, Isis remains a leader in the gene-blocking technology called antisense. But the road to successful treatments for cancer and other diseases has been littered with disappointments. During the past few ...
متن کاملEvolution of genetic switch complexity
The circuitry of the phage λ genetic switch determining the outcome of lytic or lysogenic growth is well-integrated and complex, raising the question as to how it evolved. It is plausible that it arose from a simpler ancestral switch with fewer components that underwent various additions and refinements, as it adapted to vast numbers of different hosts and conditions. We have recently identifie...
متن کاملInsensitivity to pain due to Genetic Mutation
Pain is neuroanatomically, psychologically and neurophysiologically complicated and its first function is protecting all alive creature body. This issue is so questionable and interesting that people who don’t feel pain how face this sensation and what problems threaten them. So many researchers by using 73 references, articles from electronical and library references have done a clinical...
متن کاملepileptic syndromes: from clinic to genetic.
epilepsy is one of the most common neurological disorders. studies have demonstrated that genetic factors have a strong role in etiology of epilepsy. mutations in genes encoding ion channels, neurotransmitters and other proteins involved in the neuronal biology have been recognized in different types of this disease. moreover, some chromosomal aberration including ring chromosomes will result i...
