Persistent hemiballismus with lesions outside the subthalamic nucleus.
Two patients are reported with hemiballismus due to lesions in the striatum as documented on CT scan. The involuntary movements persisted for one and five years respectively. A third patient with more typical self-limited hemiballismus had no evidence of a causative lesion on CT scan. It is proposed that lesions outside the subthalamic nucleus of Luys may interfere with the compensatory mechani...
متن کاملNesprin isoforms: are they inside or outside the nucleus?
The giant isoforms of nesprins 1 and 2 are emerging as important players in cellular organization, particularly in the positioning of nuclei, and possibly other organelles, within the cytoplasm. The experimental evidence suggests that nesprins also occur at the inner nuclear membrane, where they interact with the nuclear lamina. In this paper, we consider whether this is consistent with current...
متن کاملPhysiological importance of a circadian clock outside the suprachiasmatic nucleus.
Circadian clocks are widely distributed in mammalian tissues, but little is known about the physiological functions of clocks outside the suprachiasmatic nucleus of the brain. The retina has an intrinsic circadian clock, but its importance for vision is unknown. Here, we show that mice lacking Bmal1, a gene required for clock function, had abnormal retinal transcriptional responses to light and...
متن کاملSplicing Segregation: The Minor Spliceosome Acts outside the Nucleus and Controls Cell Proliferation
The functional relevance and the evolution of two parallel mRNA splicing systems in eukaryotes--a major and minor spliceosome that differ in abundance and splicing rate--are poorly understood. We report here that partially spliced pre-mRNAs containing minor-class introns undergo nuclear export and that minor-class snRNAs are predominantly cytoplasmic in vertebrates. Cytoplasmic interference wit...
