Doubled-haploid (DH) and single-seed-descent (SSD) lines in maize have been compared for quantitatively inherited traits and for RFLP markers. The comparisons of the distributions for agromorphological traits do not allow definite conclusions to be drawn on the similarity of the two reproductive systems. We have used more than 100 RFLP markers to provide a(More)
Elastin provides extensible tissues, including arteries and skin, with the propensity for elastic recoil, whereas amyloid fibrils are associated with tissue-degenerative diseases, such as Alzheimer's. Although both elastin-like and amyloid-like materials result from the self-organization of proteins into fibrils, the molecular basis of their differing(More)
A quantitative trait loci (QTL) analysis for androgenetic capability has been conducted on three different crosses in maize, including very high and nonresponding lines for androgenesis. The doubled haploid lines derived by anther culture from the crosses DH5 x DH7, A188 x DH7, and R6 x DH99 showed a range of 0-70%, 0-40%, and 0-50% androgenetic responding(More)
The B(2) bradykinin receptor belongs to the G-protein coupled receptor family. Development of new drugs for this important therapeutic target requires structural information on the receptor. The main goal of the present work was to overexpress the human B(2) receptor for future biophysical studies. Different tagged B(2) receptors were engineered and their(More)
The elastin binding protein (EBP), a spliced variant of lysosomal β-galactosidase, is the primary receptor of elastin peptides that have been linked to emphysema, aneurysm and cancer progression. The sequences recognized by EBP share the XGXXPG consensus pattern found in numerous matrix proteins, notably in elastin where the VGVAPG motif is repeated. To(More)
In an effort to better define the molecular mechanism of the functional specificity of human sex-determining region on the Y chromosome (SRY), we have carried out equilibrium binding assays to study the interaction of the full-length bacterial-expressed protein with a DNA response element derived from the CD3epsilon gene enhancer. These assays are based on(More)
The self-aggregation of proteins into amyloid fibrils is a pathological hallmark of numerous incurable diseases such as Alzheimer's disease. scyllo-Inositol is a stereochemistry-dependent in vitro inhibitor of amyloid formation. As the first step to elucidate its mechanism of action, we present molecular dynamics simulations of scyllo-inositol and its(More)
Although it has long been established that the extracellular matrix acts as a mechanical support, its degradation products, which mainly accumulate during aging, have also been demonstrated to play an important role in cell physiology and the development of cardiovascular and metabolic diseases. In the current study, we show that elastin-derived peptides(More)
A purified RAR/RXR-DeltaAB heterodimer was obtained by production of His-tagged RAR and untagged RXR in Escherichia coli, followed by combined purification on a Ni(2+) affinity column using excess RXR extract, and finally a gel filtration chromatography step to isolate a pure heterodimer. The purified heterodimer preparation bound 9-cisRA at a level of(More)
In the context of global water scarcity and food security concerns, water footprints are emerging as an important sustainability indicator in the agriculture and food sectors. Using a recently developed life cycle assessment-based methodology that takes into account local water stress where operations occur, the normalized water footprints of milk products(More)
