Description
The only FDA approved therapy for Pompe is directed at correcting skeletal and cardiac muscle pathology, however, clinical and animal model data show strong histological evidence for a neurological disease component. While neuronal cell death and neuroinflammation are prominent in many lysosomal disorders, these processes have not been evaluated in Pompe disease. There is also no information available regarding the impact of Pompe disease on the fundamental pathways associated with synaptic communication.

Description
Transcriptional silencing of terminal differentiation genes by the Polycomb group (PcG) machinery is emerging as a key feature of precursor cells in stem cell lineages. How, then, is this epigenetic silencing reversed for proper cellular differentiation? Here we investigate how the developmental program reverses local PcG action to allow expression of terminal differentiation genes in the Drosophila male germline stem cell lineage. We find that the silenced state, set up in precursor cells, is relieved through developmentally regulated sequential events at promoters once cells commit to spermatocyte differentiation. The programmed events include global down-regulation of PRC2, recruitment of hypophosphorylated RNA Polymerase II (Pol II) to promoters, as well as expression and action of cell-type specific homologs of subunits of TFIID (tTAFs). In addition, action of tMAC, a tissue specific version of the MIP/dREAM complex, is required both for recruitment of tTAFs to target differentiation genes and for proper cell-type specific localization of PRC1 components and tTAFs to the spermatocyte nucleolus. Together, action of the tMAC and tTAF cell-type specific chromatin and transcription machinery leads to loss of

Description
Optic nerves are an accessible part of the CNS, providing a source of glia without the presence of neuronal cell bodies. Therefore, an analysis was carried out of gene expression in optic nerves at P4, before myelination begins and at P10, when myelination is very actively proceeding. The goal was to obtain a profile of the changing gene expression that accompanies this transition from unmyelinated CNS nerve to myelinated nerve.

Description
Smac mimetics are considered as promising cancer therapeutics, but little is yet known about how they alter gene expression. In this study we used an unbiased genome-wide expression array to investigate Smac mimetic BV6-induced gene regulation in breast cancer cell lines. Kinetic analysis revealed that BV6 alters gene expression in two waves. The first wave primarily involves NF-B- and AP-1 families of transcription factors, while the second wave largely depends on tumor necrosis factor receptor 1 (TNFR1) signaling. Interestingly, disrupting auto-/paracrine tumor necrosis factor- (TNF)/ (TNFR1) signaling by knockdown of TNFR1 strongly attenuates the BV6-induced second wave of gene expression and upregulation of many pathways including NF-B signaling, apoptosis and immune signalling, but not MAPK signaling pathways. Consistently, BV6 stimulates phosphorylation of cJun, a marker of MAPK cascade activation, irrespective of the presence or absence of the TNF blocking antibody Enbrel. We show here in a comprehensive overview that BV6-induced gene expression in breast cancer cells takes place in a time- as well as TNFR1-dependent manner.
