Regulation of Synaptogenesis by the miRNA Pathway and FMR/P Bodies

Post-transcriptional regulation of mRNA is facilitated by different mechanisms, such as microRNA (miRNA) induced gene silencing or fragile X mental retardation protein (FMRP) mediated repression either independent of or acting through cytoplasmic RNA Processing bodies (P bodies). DPTP99A, Lar, and Wg have known functions during synaptogenesis and may be targets of miR-8. Here, we provide evidence that miR-8 regulates DPTP99A in vitro. Non-endogenous miR-8 expressed using an UAS driver regulates Lar. Endogenous miR-8 may regulate DPTP99A in vivo. Here we show that FMRP is capable of colocalizing with the P body components: DCP1, HPat, and Me31B, but not CCR4. We also show that RNAi against HPat and Me31B but not CCR4 and DCP1 are required for FMRP’s repression of a translational reporter in vivo. This functional analysis provides additional insight into another aspect of FMRP’s and P bodies’ ability to cooperatively control repression of mRNA targets.

"Viewers should not try this at home". Die Verfassungsgerichte Bosnien-Herzegowinas und Kosovos in deren Rolle als Schlichtungsinstanzen in ethnopolitischen Konflikten = The constitutional courts of Bosnia-Herzegovina and Kosovo in their role as arbitration bodies in ethno-political conflicts. EDAP 01/2014

The article analyzes the role of constitutional courts in Bosnia and Kosovo, both characterized by their partly internationalized membership, in the adjudication of cases that are highly controversial between the different ethno-political factions. The main focus is on the Constitutional Court of Bosnia, which presents one of the richest and most interesting examples of “lawfare” in divided societies. The concept of lawfare has been adapted to refer to the continuation of political battles by ethno-political actors through legal means, in this case, constitutional adjudication. In Kosovo, the Constitutional Court has been an important defender of diversity, albeit its primary focus and merit are to have contributed to the establishment of a concept of democracy close to the people of Kosovo. The article concludes that constitutional courts represent important institutions of internal conflict resolution in divided societies, which have been instrumental in shaping multiculturalism in these post-conflict societies divided by deep ethnic cleavages.
