TL;DR: The results indicate that antibody arrays can be used to identify differentially expressed proteins.
Abstract: We have developed a novel technique for high-throughput screening of recombinant antibodies, based on the creation of antibody arrays. Our method uses robotic picking and high-density gridding of bacteria containing antibody genes followed by filter-based enzyme-linked immunosorbent assay (ELISA) screening to identify clones that express binding antibody fragments. By eliminating the need for liquid handling, we can thereby screen up to 18,342 different antibody clones at a time and, because the clones are arrayed from master stocks, the same antibodies can be double spotted and screened simultaneously against 15 different antigens. We have used our technique in several different applications, including isolating antibodies against impure proteins and complex antigens, where several rounds of phage display often fail. Our results indicate that antibody arrays can be used to identify differentially expressed proteins.

TL;DR: The crystal structure of the fully specific complex between the DNA-binding domain from the estrogen receptor and DNA reveals how the protein recognizes its own half site sequence rather than that of the related glucocorticoid receptor, which differs by only two base pairs.

TL;DR: The structure of the δ-endotoxin from Bacillus thuringiensis subsp.
Abstract: The structure of the delta-endotoxin from Bacillus thuringiensis subsp. tenebrionis that is specifically toxic to Coleoptera insects (beetle toxin) has been determined at 2.5 A resolution. It comprises three domains which are, from the N- to C-termini, a seven-helix bundle, a three-sheet domain, and a beta sandwich. The core of the molecule encompassing all the domain interfaces is built from conserved sequence segments of the active delta-endotoxins. Therefore the structure represents the general fold of this family of insecticidal proteins. The bundle of long, hydrophobic and amphipathic helices is equipped for pore formation in the insect membrane, and regions of the three-sheet domain are probably responsible for receptor binding.

TL;DR: Increased proliferation, reduced cell death, and enhanced dopamine neuron generation in lowered O2 are demonstrated, making this method an important advance in the ex vivogeneration of specific neurons for brain repair.
Abstract: Standard cell culture systems impose environmental oxygen (O2) levels of 20%, whereas actual tissue O2 levels in both developing and adult brain are an order of magnitude lower. To address whether proliferation and differentiation of CNS precursors in vitro are influenced by the O2 environment, we analyzed embryonic day 12 rat mesencephalic precursor cells in traditional cultures with 20% O2 and in lowered O2 (3 ± 2%). Proliferation was promoted and apoptosis was reduced when cells were grown in lowered O2, yielding greater numbers of precursors. The differentiation of precursor cells into neurons with specific neurotransmitter phenotypes was also significantly altered. The percentage of neurons of dopaminergic phenotype increased to 56% in lowered O2 compared with 18% in 20% O2. Together, the increases in total cell number and percentage of dopaminergic neurons resulted in a ninefold net increase in dopamine neuron yield. Differential gene expression analysis revealed more abundant messages for FGF8, engrailed-1, and erythropoietin in lowered O2. Erythropoietin supplementation of 20% O2cultures partially mimicked increased dopaminergic differentiation characteristic of CNS precursors cultured in lowered O2. These data demonstrate increased proliferation, reduced cell death, and enhanced dopamine neuron generation in lowered O2, making this method an important advance in the ex vivogeneration of specific neurons for brain repair.
