Centrosomes: Hooked on the Nucleus
A recent study has shown that the Hook protein ZYG-12 of Caenorhabditis elegans is essential for attachment of the centrosome to the nucleus. The results suggest a novel mechanism for the tight coupling between these two organelles, and shed new light on its biological significance.
متن کاملThe 'hooked' acromion revisited.
Examination was made of 750 scapular dry bone specimens from museum collections and 80 cadaver shoulders. Hooking of the acromion was not found in subjects under the age of 30 years. The hooked configuration developed at later ages in an increasing proportion of subjects as a result of calcification of the acromial attachment of the coracoacromial ligament.
متن کاملHooked on the D3 Receptor: CaMKII's New Addiction
The dopaminergic D3 receptor (D3R) is emerging as an antagonist of sensitized behavior induced by addictive drugs such as cocaine. New work by Wang and coworkers in this issue of Neuron now identifies CaMKII as an important negative regulator of the D3R. CaMKII relieves the D3R-mediated inhibition on sensitized behavior to foster drug-seeking behavior.
متن کاملHooked on the nicotine addiction thesis: a response to DiFranza
DiFranza's rebuttal to our critique of the "Hooked on Nicotine" research program misconstrues our arguments beyond recognition. The grossest misrepresentation of our critique by DiFranza is that we devise (by thwarting science) to rescue "the conventional wisdom" of the "threshold model of nicotine addiction." In fact, the difference between our positions lies elsewhere: We believe that nicotin...
متن کاملHooked on benzodiazepines: GABAA receptor subtypes and addiction.
Benzodiazepines are widely used clinically to treat anxiety and insomnia. They also induce muscle relaxation, control epileptic seizures, and can produce amnesia. Moreover, benzodiazepines are often abused after chronic clinical treatment and also for recreational purposes. Within weeks, tolerance to the pharmacological effects can develop as a sign of dependence. In vulnerable individuals with...
