RNA–protein hybrid ribozymes that efficiently cleave any mRNA independently of the structure of the target RNA

Ribozyme activity in vivo depends on achieving high-level expression, intracellular stability, target colocalization, and cleavage site access. At present, target site selection is problematic because of unforeseeable secondary and tertiary RNA structures that prevent cleavage. To overcome this design obstacle, we wished to engineer a ribozyme that could access any chosen site. To create this ribozyme, the constitutive transport element (CTE), an RNA motif that has the ability to interact with intracellular RNA helicases, was attached to our ribozymes so that the helicase-bound, hybrid ribozymes would be produced in cells. This modification significantly enhanced ribozyme activity in vivo, permitting cleavage of sites previously found to be inaccessible. To confer cleavage enhancement, the CTE must retain helicase-binding activity. Binding experiments demonstrated the likely involvement of RNA helicase(s). We found that attachment of the RNA motif to our tRNA ribozymes leads to cleavage in vivo at the chosen target site regardless of the local RNA secondary or tertiary structure.

Supporting Access to Finance by SMEs: Mapping the initiatives in five EU countries. ECMI Research Report No. 9, April 2014

This paper maps the initiatives to support access to finance for small- and medium-sized enterprises (SMEs) that were available at national level in 2012 in the five biggest European economies (Germany, France, the UK, Italy and Spain). This mapping distinguishes initiatives promoted and financed primarily through public resources from those developed independently by the market. A second breakdown is proposed for those sources of finance with different targets, i.e. whether the target is debt financing (typically bank loans at favourable conditions, public guarantees on loans, etc.) or equity financing (typically venture capital funds, tax incentives on equity investments, etc.). A broad set of initiatives has been implemented to close the funding gap of SMEs in these five countries. The total amount of public spending for SMEs, however, has remained well below 1% of GDP. Public subsidisation of bank loans has been by far the most diffused type of intervention. Despite the fact that this strategy might prove to be effective in the short term, it fails to address long-term sustainability issues via a more diversified set of financing tools.
