  • Localization of immunoreactivity for deleted in colorectal cancer (DCC), the receptor for the guidance factor netrin-1, in ventral tier dopamine projection pathways in ad ... 15730872

    DCC (deleted in colorectal cancer)-the receptor of the netrin-1 neuronal guidance factor-is expressed and is active in the central nervous system (CNS) during development, but is down-regulated during maturation. The substantia nigra contains the highest level of netrin-1 mRNA in the adult rodent brain, and corresponding mRNA for DCC has also been detected in this region but has not been localized to any particular neuron type. In this study, an antibody raised against DCC was used to determine if the protein was expressed by adult dopamine neurons, and identify their distribution and projections. Significant DCC-immunoreactivity was detected in midbrain, where it was localized to ventrally displaced A9 dopamine neurons in the substantia nigra, and ventromedial A10 dopamine neurons predominantly situated in and around the interfascicular nucleus. Strong immunoreactivity was not detected in dopamine neurons found elsewhere, or in non-dopamine-containing neurons in the midbrain. Terminal fields selectively labeled with DCC antibody corresponded to known nigrostriatal projections to the dorsolateral striatal patches and dorsomedial shell of the accumbens, and were also detected in prefrontal cortex, septum, lateral habenular and ventral pallidum. The unique distribution of DCC-immunoreactivity in adult ventral midbrain dopamine neurons suggests that netrin-1/DCC signaling could function in plasticity and remodeling previously identified in dopamine projection pathways. In particular, a recent report that DCC is regulated through the ubiquitin-proteosome system via Siah/Sina proteins, is consistent with a potential involvement in genetic and sporadic forms of Parkinson's disease.

  • Synergy of Eed and Tsix in the repression of Xist gene and X-chromosome inactivation. 18511907

    X-chromosome inactivation (XCI) depends on the noncoding Xist gene. Xist transcription is negatively regulated by its antisense partner Tsix, whose disruption results in nonrandom XCI in females. However, males can maintain Xist in a repressed state without Tsix, indicating participation of additional factor(s) in the protection of the single male X from inactivation. Here, we provide evidence that the histone methyltransferase Eed is also involved in the process. Male embryonic stem cells with Eed-null and Tsix mutations (X(Delta)Y Eed-/-) showed Xist hyperactivation upon differentiation, whereas cells with either mutation alone did not. Impaired X-linked gene expression was observed in the X(Delta)Y Eed-/- ES cells at the onset of differentiation. The Xist promoter in the X(Delta)Y Eed-/- cells showed elevated histone H3-dimethyl lysine 4 modifications and lowered CpG methylation, which are characteristics of open chromatin. Hence, we identified Eed as an additional major player in the regulation of Xist expression. The synergy of Polycomb group proteins and antisense Tsix transcription in Xist gene regulation explains why males can repress Xist without Tsix.
