Electrochemical Detection of Global DNA Methylation Using Biologically Assembled Polymer Beads.

DNA methylation is a cell-type-specific epigenetic marker that is essential for transcriptional regulation, silencing of repetitive DNA and genomic imprinting. It is also responsible for the pathogenesis of many diseases, including cancers. Herein, we present a simple approach for quantifying global DNA methylation in ovarian cancer patient plasma samples based on a new class of biopolymer nanobeads.

Bioengineered Polymer Nanobeads for Isolation and Electrochemical Detection of Cancer Biomarkers.

Early sensitive diagnosis of cancer is critical for enhancing treatment success. We previously bioengineered multifunctional core-shell structures composed of a poly-3-hydroxybutyrate (PHB) core densely coated with protein functions for uses in bioseparation and immunodiagnostic applications. Here, we report bioengineering of to self-assemble PHB inclusions that codisplay a ferritin-derived iron-binding peptide and the protein A-derived antibody-binding Z domain.

Polymeric nanoparticle vaccines to combat emerging and pandemic threats.

Subunit vaccines are more advantageous than live attenuated vaccines in terms of safety and scale-up manufacture. However, this often comes as a trade-off to their efficacy. Over the years, polymeric nanoparticles have been developed to improve vaccine potency, by engineering their physicochemical properties to incorporate multiple immunological cues to mimic pathogenic microbes and viruses.

Polyester as Antigen Carrier toward Particulate Vaccines.

Spherical polyhydroxyalkanoate (PHA) inclusions are naturally self-assembled inside bacteria. These PHA beads are shell-core structures composed of a hydrophobic PHA core surrounded by proteins, such as PHA synthase (PhaC). PhaC is covalently attached and serves as an anchor protein for foreign protein vaccine candidate antigens.

Multiple abiotic stimuli are integrated in the regulation of rice gene expression under field conditions.

Plants rely on transcriptional dynamics to respond to multiple climatic fluctuations and contexts in nature. We analyzed the genome-wide gene expression patterns of rice (Oryza sativa) growing in rainfed and irrigated fields during two distinct tropical seasons and determined simple linear models that relate transcriptomic variation to climatic fluctuations. These models combine multiple environmental parameters to account for patterns of expression in the field of co-expressed gene clusters.
