Processing of N‐Terminal Unnatural Amino Acids in Recombinant Human Interferon‐β in Escherichia coli
Authors: Wang Aijun , Winblade Nairn Natalie , Johnson Richard S. , Tirrell David A. , Grabstein Kenneth 
Published: December 2007

AbstractIncorporation of unnatural amino acids into recombinant proteins represents a powerful tool for protein engineering and protein therapeutic development. While the processing of the N‐terminal methionine (Met) residues in proteins is well studied, the processing of unnatural amino acids used for replacing the N‐terminal Met remains largely unknown. Here we report the effects of the penultimate residue (the residue after the initiator Met) on the processing of two unnatural amino acids, L‐azidohomoalanine (AHA) and L‐homopropargylglycine (HPG), at the N terminus of recombinant human interferon‐β in E. coli. We have identified specific amino acids at the penultimate position that can be used to efficiently retain or remove N‐terminal AHA or HPG. Retention of N‐terminal AHA or HPG can be achieved by choosing amino acids with large side chains (such as Gln, Glu, and His) at the penultimate position, while Ala can be selected for the removal of N‐terminal AHA or HPG. Incomplete processing of N‐terminal AHA and HPG (in terms of both deformylation and cleavage) was observed with Gly or Ser at the penultimate position.

AbstractObjective: We report our experience with the elective placement of below‐knee, drug‐eluting stents in patients with chronic limb ischemia. Background: Infrapopliteal percutaneous transluminal angioplasty has been associated with a lower rate of procedural success and high rate of restenosis because of the small size of the tibial vessels and the prevalence of calcified and diffuse atherosclerotic disease. Prior published data reports 3‐year patency rates below 25%. Bare metal stents have been reported in bailout situations. Drug‐eluting stents have markedly reduced restenosis compared to bare metal stents in the coronary vasculature, but there is little data supporting the use of these devices below the knee. Methods: Elective placement of drug‐eluting stents in infrapopliteal lesions was performed on 10 patients with severe (≥Fontaine Stage IIb) claudication (n = 1) or limb‐threatening ischemia (n = 9) (rest pain, nonhealing ulcers and gangrene). Results: A total of 17 drug‐eluting stents were electively placed in 12 below‐knee arteries in 10 patients, resulting in an average of 1.7 ± 0.7 stents per patient. The mean lesion length was 24.8 ± 10.9 mm, the mean total stent length was 38.3 ± 19.1 mm, and the mean nominal stent diameter was 2.8 ± 0.3 mm. One patient required target vessel revascularization (TVR) at 3 weeks because of stent thrombosis. TVR was 10% at 12.4 ± 6.5 months of follow‐up. Clinically driven angiography in three different patients was performed at 4, 15, and 16 months and confirmed drug‐eluting stent patency in each case. Conclusions: The use of below‐knee drug‐eluting stents is feasible and appears to be safe in our small series of complex infrapopliteal lesions causing chronic limb ischemia. The occurrence of a single case of stent thrombosis warrants continued observation in this cohort. Prospective clinical trials will be necessary to confirm the benefits and justify the costs of this strategy for treating patients with infrapopliteal culprit lesions and chronic limb ischemia. © 2008 Wiley‐Liss, Inc.
CTO recanalization by intraocclusion injection of contrast: The microchannel technique

Published: December 2007

AbstractObjectives: To assess the utilization of microinjection of contrast for the recanalization of chronic total occlusions (CTO). Background: Microchannels in CTOs have been considered important conduits for CTO crossing, utilizing dedicated guidewires. We postulated that microinjection of contrast immediately distal to the proximal cap of the CTO could identify and enlarge these microvessels, creating a passage for crossing the CTO with a floppy guidewire. Methods: A total of 32 patients with a CTO were treated with this technique. Following few millimetres penetration of the proximal fibrous cap of the occlusion with a dedicated CTO guidewire, the over‐the‐wire balloon was advanced into the proximal portion of the occlusion, and 50–100 μg of nitroglycerine followed by 1 ml of contrast was gently injected into the occluded segment. Technical success of the microchannel technique was defined as the ability to visualize the distal true lumen with microinjection of contrast and thereafter cross the CTO with a floppy guidewire in the absence of any dissection. Results: Overall, technical success of the microchannel technique was obtained in 20 (63%) with angiographic success in 19. In 12 (37%) cases there was a technical failure because of dissection, and we obtained recanalization of the artery in 7 of these 12 cases with another technique. There was only one case of periprocedural myocardial infarction in an unsuccessful procedure and no major adverse cardiac events or subacute stent thromboses were observed. Conclusions: Microinjection of contrast immediately distal to the proximal fibrous cap of a CTO may be an additional technique to facilitate recanalization of CTO. © 2008 Wiley‐Liss, Inc.
