Appropriate regulation of hematopoietic stem cell (HSC) self-renewal is critical for the maintenance of life long hematopoiesis. However, long-term repeated cell divisions induce the accumulation of DNA damage, especially at telomere, significantly compromises HSC function. Therefore, shelterin elements Pot1a is required to prevent DNA damage response at telomeres in order to maintain their function.

View SamplesIL28B genotype was shown to be associated with treatment outcome of antiviral thearpy for HCV infection. We tried to clarify the molecular feature that was asocciated with IL2B genotype by comparing Hepatic gene expression of HCV related Hepatocellular carcinoma and non-cancerous tissue with Il28B rs8099917 TT genotype and TG/GG genotype.

View SamplesSpinal interneurons are critical modulators of locomotor circuit function. In the dorsal spinal cord, a set of interneurons called GABApre presynaptically inhibits proprioceptive sensory afferent terminals, thus negatively regulating sensory-motor signaling. While deficits in presynaptic inhibition have been inferred in human locomotor diseases, including dystonia, it remains unknown whether GABApre circuit components are altered in these conditions. In this study, we use developmental timing to show that GABApre neurons are a late Ptf1a-expressing subclass and localize to the intermediate spinal cord. Using a microarray screen to identify genes expressed in this intermediate population, we find the kelch-like family member Klhl14, implicated in dystonia through its direct binding with torsion-dystonia related protein Tor1a. Furthermore, in Tor1a mutant mice in which Klhl14 and Tor1a binding is disrupted (Dyt1E), GABApre-sensory afferent synapse formation is impaired. Our findings suggest a potential contribution of GABApre neurons to the deficits in presynaptic inhibition observed in dystonia.
