A widely applicable, positive cDNA selection method was developed to identify RNAs synthesized by Mycobacterium tuberculosis in response to phagocytosis by cultured human primary macrophages. cDNAs for sigE and sigH (alternative sigma factors), aceA (isocitrate lyase), ponA (class I penicillin-binding protein), pks2 (polyketide synthase), uvrA (UvrABC(More)
In this work a series of ABA tri-block copolymers was prepared from oligo(ethylene glycol) methyl ether methacrylate (OEGMA(475)) and N,N-dimethylaminoethyl methacrylate (DMAEMA) to investigate the effect of polymer composition on cell viability, siRNA uptake, serum stability and gene silencing. Reversible Addition-Fragmentation Chain Transfer (RAFT)(More)
The in vitro function of the coliphage lambda tR1 Rho-dependent terminator is governed primarily by a tripartite upstream sequence element designated rut. To determine the contribution of the different components of the rut site to terminator function in the normal context of coupled translation of the nascent cro message, tR1 variants lacking different rut(More)
A number of omega-conotoxin GVIA mimetics based on an anthranilamide core were prepared and tested for their affinity for rat brain Ca(v)2.2 channels. Features such as the presence of hydroxyl and fluoro substituents on the tyrosine side chain mimic, the length of the chains on the lysine/arginine side chain mimics and the use of diguanidino and diamino(More)
A set of fluorophenoxyanilides, designed to be simplified analogues of previously reported ω-conotoxin GVIA mimetics, were prepared and tested for N-type calcium channel inhibition in a SH-SY5Y neuroblastoma FLIPR assay. N-type or Cav2.2 channel is a validated target for the treatment of refractory chronic pain. Despite being significantly less complex than(More)
