难治性癫痫,即对目前可用的疗法没有反应的癫痫发作障碍,是困难的,通常是悲惨的神经系统疾病。Na+通道病与一些难治性癫痫(包括Dravet综合征)有关,但在治疗方面进展甚微。在这里,我们研究了果蝇模型的难治性癫痫,Na+通道功能获得性突变parabss 1类似Dravet综合征在某些方面。特别是,我们确定了第二个网站的突变与parabss 1,癫痫发作增强剂,癫痫发作抑制剂。我们描述了一个名为江湖郎中(chn)的突变。chn基因通常编码神经元特异性基因的神经元限制性沉默因子/RE 1沉默转录因子转录抑制因子。我们确定了第二个位点的等位基因抑制突变,吉尔伽美什(gish),减少了几个等位基因样表型的parabss 1/+杂合子的严重程度。gish基因通常编码酪蛋白激酶CK 1g 3的果蝇直向同源物,CK 1是丝氨酸-苏氨酸激酶家族的成员。我们认为,CK 1g 3是一个意想不到的,但有前途的癫痫治疗的新靶点。
Intractable epilepsies, that is, seizure disorders that do not respond to currently available therapies, are difficult, often tragic, neurological disorders. Na+ channelopathies have been implicated in some intractable epilepsies, including Dravet syndrome, but little progress has been forthcoming in therapeutics. Here we examine a Drosophila model for intractable epilepsy, the Na+ channel gain-of-function mutant parabss1 that resembles Dravet syndrome in some aspects. In particular, we identify second-site mutations that interact with parabss1, seizure enhancers, and seizure suppressors. We describe one seizure-enhancer mutation named charlatan (chn). The chn gene normally encodes an Neuron-Restrictive Silencer Factor/RE1-Silencing Transcription factor transcriptional repressor of neuronal-specific genes. We identify a second-site seizure-suppressor mutation, gilgamesh (gish), that reduces the severity of several seizure-like phenotypes of parabss1/+ heterozygotes. The gish gene normally encodes the Drosophila ortholog of casein kinase CK1g3, a member of the CK1 family of serine-threonine kinases. We suggest that CK1g3 is an unexpected but promising new target for seizure therapeutics.
