TL;DR: This work reports that apoA-I signals in the macrophage through Toll-like receptor2, TLR4, and CD14, utilizing myeloid differentiation primary response protein 88 (MyD88)-dependent and -independent pathways, to activate nuclear factor-kappaB and induce cytokines and identifies innate immunity as a physiologic signal in cholesterol homeostasis.

TL;DR: It is revealed that, with only two amino acid replacements, an enzyme capable of functioning exclusively as a hydrolase can be converted into an equally active enzyme performing solely as an acyltransferase.

TL;DR: It is proposed that APOE4 carriers have impaired brain transport of free DHA but not of DHA‐lysoPC, as a consequence of a breakdown in the outer membrane leaflet of the blood–brain barrier, putting them at increased risk for AD.
Abstract: Dietary and supplemental intake of the ω-3 fatty acid docosahexaenoic acid (DHA) reduces risk of Alzheimer's disease (AD) and ameliorates symptoms. The apolipoprotein E ( APOE) 4 allele is the strongest risk factor for sporadic AD, exclusive of age. APOE4 carriers respond well to the DHA present in fish but do not respond as well to dietary supplements. The mechanisms behind this varied response remain unknown. I posit that the difference is that fish contain DHA in phospholipid form, whereas fish oil supplements do not. This influences whether DHA is metabolized to nonesterified DHA (free DHA) or a phospholipid form called lysophosphatidylcholine DHA (DHA-lysoPC). Free DHA is transported across the outer membrane leaflet of the blood-brain barrier (BBB) via passive diffusion, and DHA-lysoPC is transported across the inner membrane leaflet of the BBB via the major facilitator superfamily domain-containing protein 2A. I propose that APOE4 carriers have impaired brain transport of free DHA but not of DHA-lysoPC, as a consequence of a breakdown in the outer membrane leaflet of the BBB, putting them at increased risk for AD. Dietary sources of DHA in phospholipid form may provide a means to increase plasma levels of DHA-lysoPC, thereby decreasing the risk of AD.-Patrick, R. P.

TL;DR: It is found that the gene linkage detected in all vertebrate genomes has been maintained in the primitively appendage-lacking, basal chordate, amphioxus.
Abstract: T-box genes encode a family of DNA-binding transcription factors implicated in numerous developmental processes in all metazoans. The Tbx2/3/4/5 subfamily genes are especially interesting because of their key roles in the evolution of vertebrate appendages, eyes, and the heart, and, like the Hox genes, the longevity of their chromosomal linkage. A BAC library derived from the single male amphioxus (Branchiostoma floridae) used to sequence the amphioxus genome was screened for AmphiTbx2/3 and AmphiTbx4/5, yielding two independent clones containing both genes. Using comparative expression, genomic linkage, and phylogenetic analyses, we have reconstructed the evolutionary histories of these members of the T-box gene family. We find that the Tbx2–Tbx4 and Tbx3–Tbx5 gene pairs have maintained tight linkage in most animal lineages since their birth by tandem duplication, long before the divergence of protostomes and deuterostomes (e.g., arthropods and vertebrates) at least 600 million years ago, and possibly before the divergence of poriferans and cnidarians (e.g., sponges and jellyfish). Interestingly, we find that the gene linkage detected in all vertebrate genomes has been maintained in the primitively appendage-lacking, basal chordate, amphioxus. Although all four genes have been involved in the evolution of developmental programs regulating paired fin and (later) limb outgrowth and patterning, and most are also implicated in eye and heart development, linkage maintenance—often considered due to regulatory constraints imposed by limb, eye, and/or heart associated gene expression—is undoubtedly a consequence of other, much more ancient functional constraints.

TL;DR: It is demonstrated that the four plasmid genotypes of B. anthracis and B. cereus group near-neighbors were differentially and simultaneously discriminated by this assay.
Abstract: Bacillus anthracis has four plasmid possible virulence genotypes: pXO1+/pXO2+, pXO1+/pXO2−, pXO1−/pXO2+ or pXO1−/pXO2−. Due to the lack of a specific chromosomal marker for B. anthracis, differentiation of the pXO1−/pXO2− form of B. anthracis from closely related Bacillus cereus group species is difficult. In this study, we evaluate the ability of sspE, pXO1 and pXO2 primers to discriminate individual B. anthracis and the B. cereus group genotypes using multiplex real-time PCR and melting curve analysis. Optimal conditions for successful multiplex assays have been established. Purified DNAs from 38 bacterial strains including 11 strains of B. anthracis and 18 B. cereus group strains were analyzed. Nine of the B. cereus group near-neighbor strains were shown by multilocus sequence typing to be phylogenetically proximate to the B. anthracis clade. We have demonstrated that the four plasmid genotypes of B. anthracis and B. cereus group near-neighbors were differentially and simultaneously discriminated by this assay.
