Background technology
UBE3A coding for targeting specific albumen with degrade ubiquitin E3 ligases (de Bie, P. and Ciechanover A.(2011)Cell Death Differ.18:1393-402), and since it is as main general in cynapse The protein-bonded effect of element, thus it is most important in terms of cognitive function of bringing into normal play.UBE3A removes cynapse signal conductive protein The ability of (for example, Arc) allows for the homologous adjusting of neurite outgrowth.The forfeiture of UBE3A expression can be destroyed via transcription factor The long-term enhancing of Arc, and also result in the imbalance of glutamate receptor activity.Over time, UBE3A missings cause cynapse to be dropped Solution and epileptic attack.
The attenuation of correlation of UBE3A functional disturbances and cognitive function joins.In particular, it with certain obstacles (for example, Angelman syndrome) the origin cause of formation it is related.
Angelman syndrome is a kind of genetic block, leads to functionally serious hypoevolutism, it is characterised in that serious Disfluency, movement or disequilibrium and abnormal behaviour.
It is estimated that only America & Canada just has 1000 to 5000 Angelman syndrome cases.
Drug can be used sometimes with the relevant epileptic attack of Angelman syndrome or controlled using high fat diet, so And improved Atkins diet has also been attempted in this context, but the success of these methods is variable.
The nearest certain cancer drugs of studies have shown that can induce UBE3A, and in Angelman syndrome mouse mould Show that behavior improves (Huang, H.S. et al. (2011) Nature 481 using particular cancers drug in type:185-9).So And these drugs are not that brain is bioavailable, such cancer drug inhibits cell division in addition, and is not suitable for The long-term treatment of Angelman syndrome patient.
Using antibiotic, to methylate nutriment and antioxidant several for treating Angelman syndrome to carry out Clinical test, these substances be all proved to cognition or behavior almost without any effect.Therefore, it there is no at present for the disease The reliable treatment of disease.
Prader-Willi syndromes are a kind of and relevant genetic block of Angelman syndrome.Prader-Willi is comprehensive Simulator sickness patient has significant cognition, nerve, endocrine and abnormal behavior.Further, since hypotony, patient may be in baby Phase is difficult to feed, and leads to growth retardation, but due to the uncontrollable craving of food, becoming fertilizer afterwards in the life that they can be It is fat.
The whole world about 400,000 patients suffer from Prader-Willi syndromes.
Although behavior therapy and other treatments can reduce the influence of Prader-Willi syndromes, do not have for the disease Effective treatment.
Therefore, for up-regulation brain in UBE3A expression with improve cognitive function method continue there is notable demands.Separately Outside, hence it is evident that also need to for treating disease such as Angelman syndrome and Prader-Willi syndromes, being specifically used for The method for solving the treatment of its relevant cognitive impairment.
