The Impact Of Inward Licensing On New Venture’s Performance. Is inward licensing a winning strategy?

The original idea of the thesis draws on interrelated assumptions: 1) among the tools used, in the markets for technology, for the acquisition of external knowledge, the licensing agreements are acknowledged as one of the most important contractual mechanisms; 2) the liabilities of newness and the liabilities of smallness force new venture to strongly rely on external knowledge sources. Albeit the relevance of this topic, little attention has been paid so far to its investigation, especially in the licensing context; 3) nowadays there is an increasing trend in licensing practices, but the literature on markets for technology focuses almost exclusively on the incentives and rationales that foster firms’ decisions to trade their technologies, under-investigating the role of the acquiring firm, the licensee, overlooking the demand side of the market. Therefore, the thesis investigates the inward licensing phenomenon within the context of new ventures. The main questions that new venture licensee has to address if it decides to undertake an inward licensing strategy, can be summarized as follows: 1) Is convenient for a new venture to choose, as initial technology strategy, the implementation of an inward licensing ? 2) Does this decision affect its survival probabilities? 3) Does the age, at which a new venture becomes a licensee, affect its innovative capabilities? Is it better to undertake a licensing-in strategy soon after founding or to postpone this strategy until the new venture has accumulated significant resources? The findings suggest that new ventures licensees survive less than their non-licensee counterparts; the survival rates are directly connected to the time taken by firms to reach the market;being engaged in licensing-in deals some years after its inception allows a new venture licensee to increase its subsequent capacity to produce innovations.

A novel RNA polymerase I-dependent RNase activity that shortens nascent transcripts from the 3′ end

A novel RNase activity was identified in a yeast RNA polymerase I (pol I) in vitro transcription system. Transcript cleavage occurred at the 3′ end and was dependent on the presence of ternary pol I/DNA/RNA complexes and an additional protein factor not identical to transcription factor IIS (TFIIS). Transcript cleavage was observed both on arrested complexes at the linearized ends of the transcribed DNA and on intrinsic blocks of the DNA template. Shortened transcripts that remained associated within the ternary complexes were capable of resuming RNA chain elongation. Possible functions of the nuclease for transcript elongation or termination are discussed.

Functional topography of nascent RNA in elongation intermediates of RNA polymerase

To determine the dynamics of transcript extrusion from Escherichia coli RNA polymerase (RNAP), we used degradation of the RNA by RNases T1 and A in a series of consecutive elongation complexes (ECs). In intact ECs, even extremely high doses of the RNases were unable to cut the RNA closer than 14–16 nt from the 3′ end. Our results prove that all of the cuts detected within the 14-nt zone are derived from the EC that is denatured during inactivation of the RNases. The protected zone monotonously translocates along the RNA after addition of new nucleotides to the transcript. The upstream region of the RNA heading toward the 5′ end is cleaved and dissociated from the EC, with no effect on the stability and activity of the EC. Most of the current data suggest that an 8- to 10-nt RNA⋅DNA hybrid is formed in the EC. Here, we show that an 8- to 10-nt RNA obtained by truncating the RNase-generated products further with either GreB or pyrophosphate is sufficient for the high stability and activity of the EC. This result suggests that the transcript–RNAP interaction that is required for holding the EC together can be limited to the RNA region involved in the 8- to 10-nt RNA⋅DNA hybrid.
