    Precisely Alternating Functionalized Polyampholytes Prepared in a Single Pot from Sustainable Thiolactone Building Blocks

    No full text
    Polyampholytes with precisely alternating cationic and anionic functional groups were prepared using sustainable thiolactone building blocks in a simple one-pot procedure at room temperature and in water. Ring opening of the <i>N-</i>maleamic acid-functionalized homocysteine thiolactone monomer enabled the introduction of different functional groups into the polymer chain, which contributed to both ionic and hydrogen bonding interactions. The resulting polyampholytes exhibited various isoelectric points while maintaining high solubility in water under different pH and ionic strengths, which expands their potential applications. Finally, it is shown that the upper critical solution temperature (UCST) of these alternating polyampholytes in water/ethanol (30/70% vol) solutions can be tuned as a function of the content of ionic and hydroxyl groups

    Diet-based comparisons of enzyme expression in pantothenate pathway. Two comparisons are shown: (A) Plin2-HF vs. Plin2-LF and (B) WT-HF vs. WT-LF. Circular nodes indicate enzymes, with size indicating relative difference in expression between sample types and color indicating direction of change (see inset key). Associated heatmaps indicate global changes in expression for each enzyme, in addition to taxon-specific changes in expression for each of the 17 defined taxa colored according to phylum. The following abbreviations are used: 5,6-dh-uracil (5,6-dihydro-uracil), N-cm-β-alanine (N-carbamoyl-β-alanine), N-pt-Cys (N-pantothenoyl-cysteine), and (R)-4′-P-pt-L-Cys ((R)-4′-phospho-pantothenoyl-l-cysteine.

    Comparison of glycolysis pathway enzyme expression between sample types. Three comparisons are shown: (A) Plin2-LF vs. WT-LF; (B) Plin2-HF vs. Plin2-LF; (C) WT-HF vs. WT-LF. Circular nodes indicate enzymes, with size indicating relative difference in expression between sample types and color indicating direction of change (see inset key). Associated heatmaps indicate global changes in expression for each enzyme, in addition to taxon-specific changes in expression for each of the 17 defined taxa colored according to phylum.

    Rarefaction analysis of annotated mRNA reads. Recovery of species (A) and enzymes (B) with increasing numbers of annotated mRNA reads (reads mapped to known transcripts) indicate that sequencing depth for each sample was sufficient to recover the vast majority of species and enzymes present within each of the 16 samples. Rarefaction analysis was performed using R. (PDF 16825 kb

    Phenylketonuria (PKU) is an inborn error of metabolism caused by a deficiency in functional phenylalanine hydroxylase (PAH), resulting in accumulation of phenylalanine (Phe) in patients’ blood and organs. Affected patients encounter severe developmental delay, neurological deficits, and behavioral abnormalities when not treated. Early diagnosis and treatment are extremely important; newborn screening programs have been implemented in most countries to ensure early identification of patients with PKU. Despite available treatment options, several challenges remain: life-long adherence to a strict diet, approval of some medications for adults only, and lack of response to these therapies in a subpopulation of patients. Therefore, there is an urgent need for treatment alternatives. An mRNA-based approach tested in PKU mice showed a fast reduction in the accumulation of Phe in serum, liver and brain, the most significant organ affected. Repeated injections of LNP-formulated mouse PAH mRNA rescued PKU mice from the disease phenotype for a prolonged period of time. An mRNA-based approach could improve the quality of life tremendously in PKU patients of all ages by replacing standard-of-care treatments.</p
