By the time the British ecologist Charles Elton wrote his famous 1958 book The Ecology of Invasions by Animals and Plants, some 40 scientists had published descriptions of non-natives, but no consensus had been reached on the desirability of intervening when alien species were introduced. 32, 407417 (2010). The present paper traces the history of the debate and attempts to explain the theory's longevity and vitality in the face of what has amounted to largely negative assessments by other sociologists over the preceding fifty years. . To ascertain whether the targeted delivery system can provide effective delivery of functional siRNA to human tumours, we investigated biopsies from three patients from three different dosing cohorts; patients A, B and C, all of whom had metastatic melanoma and received CALAA-01 doses of 18, 24 and 30mgm-2 siRNA, respectively.

Most notably, we detect the presence of an mRNA fragment that demonstrates that siRNA-mediated mRNA cleavage occurs specifically at the site predicted for an RNAi mechanism from a patient who received the highest dose of the nanoparticles.

Intentionally or not, such characterizations have helped to create a pervasive bias against alien species that has been embraced by the public, conservationists, land managers and policy-makers, as well by as many scientists, throughout the world. We are at present conducting the first in-human phase I clinical trial involving the systemic administration of siRNA to patients with solid cancers using a targeted, nanoparticle delivery system. PCR products were excised from the gel and sequenced directly to confirm RACE band identities. The targeted nanoparticles (about 70-nm diameter) were administered intravenously, as they are designed to circulate and then to accumulate and permeate in solid tumours13.

Because of the limited sample amount, only immunohistochemistry (IHC) and staining for the nanoparticles could be performed on the C1pre and C1post samples, and protein (for western blot analyses) was only available from the C2pre and C2post samples. Therapeutics that are designed to engage RNA interference (RNAi) pathways have the potential to provide new, major ways of imparting therapy to patients1,2.

Increasingly, the practical value of the native-versus-alien species dichotomy in conservation is declining, and even becoming counterproductive1. Professor, University of Florida. After phenol extraction and ethanol precipitation, the purified ligation products were reverse-transcribed using SuperScriptIII (Invitrogen) and an RRM2 gene-specific reverse-transcription primer (5-CTCTCTCCTCCGATGGTTTG-3) at 55C for 45min followed by inactivation at 70C.

Patient C had stable disease between these biopsies, and these mostly quiescent tumours have very slow growth kinetics that would be suitable to experience lengthy RNAi effects25. The bar graph shows the average volume of western blot bands from two independent experiments; one representative blot is pictured. Rep. 15, 12991304 (2006), CAS Because the nanoparticles are observed in the sample C1post and not the sample C2pre, they must disassemble within 1month. Furthermore, this result indicates that at least a portion of the RRM2 mRNA and protein reductions observed from the C2 samples are due to a bona fide RNAi mechanism. Since then, several delivery vehicles have been combined with siRNAs to improve their delivery in animal models1,2. Wiley DT, 5-RLM-RACE-PCR was performed using the GeneRacer 5 primer (5-CGACTGGAGCACGAGGACACTGA-3) and an RRM2 gene-specific reverse primer (5-GGCCAGGCATCAGTCCTCGTTTCTTG-3).

Tumour biopsies from melanoma patients obtained after treatment show the presence of intracellularly localized nanoparticles in amounts that correlate with dose levels of the nanoparticles administered (this is, to our knowledge, a first for systemically delivered nanoparticles of any kind). Natl Acad. Formalin-fixed, paraffin-embedded human tissue samples from patient-matched pre- and post-treatment cases were obtained under UCLA Institutional Review Board (IRB) approval. This formulation was the first targeted siRNA nanoparticle formulation to enter into human clinical trials.5, 6 The second technology was a polymerdrug conjugate using sugarbased polymers to stabilize and deliver camptothecin, and anticancer agent.7, 8 This platform, is now being evaluated in phase II clinical trials by Cerulean Pharma.

Although there are animal studies that do support the possibility of an RNAi mechanism of action from administered siRNA11, other animal data from siRNAs injected into the eyes of mice for the treatment of CNV suggest non-RNAi mechanisms of action for CNV suppression12. Because RRM2 protein expression is largely restricted to the late G1/early S phase of the cell cycle, not all of the tumour cells will be expressing RRM2.

Efficient delivery of siRNA for inhibition of gene expression in postnatal mice. Because samples Apre and Bpre are from tissues collected many months before the initiation of siRNA treatment, the fraction of the overall reduction in mRNA observed in Apost and Bpost attributable to the nanoparticle treatment cannot be directly ascertained.
