Chilunga 1 , Peter Henneman2, Andrea Venema2, Karlijn A. C. Meeks 3, Ana Requena-Méndez4,5, Erik Beune1, Frank P. Mockenhaupt6, Liam Smeeth7, Silver Bahendeka8, Ina Danquah9, Kerstin Klipstein-Grobusch10,11, Adebowale Adeyemo 3, Marcel M.A.M Mannens2 and Charles Agyemang1 Molecular mechanisms at the intersection of inflammation and cardiovascular diseases (CVD) among Africans are still unknown. We performed an epigenome-wide association study to identify loci associated with serum C-reactive protein (marker of inflammation) among Ghanaians and further assessed whether differentially methylated positions (DMPs) were linked to CVD in previous reports, or to estimated CVD risk in the same population. We used the Illumina Infinium® HumanMethylation450 BeadChip to obtain DNAm profiles of blood samples in 589 Ghanaians from the RODAM study (without acute infections, not taking anti-inflammatory medications, CRP levels < 40 mg/L). We then used linear models to identify DMPs associated with CRP concentrations. Post-hoc, we evaluated associations of identified DMPs with elevated CVD risk estimated via ASCVD risk score. We also performed subset analyses at CRP levels ≤10 mg/L and replication analyses on candidate probes. Finally, we assessed for biological relevance of our findings in public databases. We subsequently identified 14 novel DMPs associated with CRP. In post-hoc evaluations, we found 1234567890():,; that DMPs in PC, BTG4 and PADI1 showed trends of associations with estimated CVD risk, we identified a separate DMP in MORC2 that was associated with CRP levels ≤10 mg/L, and we successfully replicated 65 (24%) of previously reported DMPs. -

The HSP70 Chaperone Machinery: J Proteins As Drivers of Functional Specificity
REVIEWS The HSP70 chaperone machinery: J proteins as drivers of functional specificity Harm H. Kampinga* and Elizabeth A. Craig‡ Abstract | Heat shock 70 kDa proteins (HSP70s) are ubiquitous molecular chaperones that function in a myriad of biological processes, modulating polypeptide folding, degradation and translocation across membranes, and protein–protein interactions. This multitude of roles is not easily reconciled with the universality of the activity of HSP70s in ATP-dependent client protein-binding and release cycles. Much of the functional diversity of the HSP70s is driven by a diverse class of cofactors: J proteins. Often, multiple J proteins function with a single HSP70. Some target HSP70 activity to clients at precise locations in cells and others bind client proteins directly, thereby delivering specific clients to HSP70 and directly determining their fate. In their native cellular environment, polypeptides are participates in such diverse cellular functions.

Lind1 and Katherine S. Pollard1,2,3,4,5* Abstract Background: Microbial eukaryotes are found alongside bacteria and archaea in natural microbial systems, including host-associated microbiomes. While microbial eukaryotes are critical to these communities, they are challenging to study with shotgun sequencing techniques and are therefore often excluded. Results: Here, we present EukDetect, a bioinformatics method to identify eukaryotes in shotgun metagenomic sequencing data. Our approach uses a database of 521,824 universal marker genes from 241 conserved gene families, which we curated from 3713 fungal, protist, non-vertebrate metazoan, and non-streptophyte archaeplastida genomes and transcriptomes. EukDetect has a broad taxonomic coverage of microbial eukaryotes, performs well on low-abundance and closely related species, and is resilient against bacterial contamination in eukaryotic genomes. Using EukDetect, we describe the spatial distribution of eukaryotes along the human gastrointestinal tract, showing that fungi and protists are present in the lumen and mucosa throughout the large intestine. We discover that there is a succession of eukaryotes that colonize the human gut during the first years of life, mirroring patterns of developmental succession observed in gut bacteria. By comparing DNA and RNA sequencing of paired samples from human stool, we find that many eukaryotes continue active transcription after passage through the gut, though some do not, suggesting they are dormant or nonviable. We analyze metagenomic data from the Baltic Sea and find that eukaryotes differ across locations and salinity gradients. -

Simple Summary: In this study, we investigated the expression pattern and prognostic significance of the heat shock proteins (HSPs) family members in breast cancer (BC) by using several bioinfor- matics tools and proteomics investigations. Our results demonstrated that, collectively, HSPs were deregulated in BC, acting as both oncogene and onco-suppressor genes. In particular, two different HSP-clusters were significantly associated with a poor or good prognosis. Interestingly, the HSPs deregulation impacted gene expression and miRNAs regulation that, in turn, affected important bio- logical pathways involved in cell cycle, DNA replication, and receptors-mediated signaling. Finally, the proteomic identification of several HSPs members and isoforms revealed much more complexity Citation: Buttacavoli, M.; Di Cara, of HSPs roles in BC and showed that their expression is quite variable among patients. In conclusion, G.; D’Amico, C.; Geraci, F.; we elaborated two panels of HSPs that could be further explored as potential biomarkers for BC Pucci-Minafra, I.; Feo, S.; Cancemi, P. -

Embargoed until 9 a.m. (EDT) August 13, 2015 STATISTICAL ADVANCES HELP UNLOCK MYSTERIES OF THE HUMAN MICROBIOME SEATTLE, WA, AUGUST 13, 2015 – Advances in the field of statistics are helping to unlock the mysteries of the human microbiome—the vast collection of microorganisms living in and on the bodies of humans, said Katherine Pollard, a statistician and biome expert, during a session today at the 2015 Joint Statistical Meetings (JSM 2015) in Seattle. Pollard, senior investigator at the Gladstone Institutes and professor of epidemiology and biostatistics at the University of California, San Francisco, delivered a presentation titled “Estimating Taxonomic and Functional Diversity in Shotgun Metagenomes” during an invited session focused on statistics, the microbiome and human health. “While we are only just beginning to understand the complex roles microbes play in human biology, it is clear specific changes in microbial flora are associated with—and sometimes cause or cure—disease in the host,” said Pollard while explaining her research focus. “Some of the best-supported links are with autoimmune diseases, which are on the rise in the United States, perhaps due to antibiotic use and lack of exposure to a diverse collection of microbes during childhood. This ‘hygiene hypothesis’ suggests that health risks not attributable to human genetics and behavior may stem from differences in microbiome composition between individuals.” What’s more, a given microbial species can share less than 50% of the same genes when found in two people. These differences track with functional capabilities of the microbial communities, including genes related to sugar metabolism, biosynthesis and two-component systems. -
Morphology, Behavior, and the Sonic Hedgehog Pathway in Mouse Models of Down Syndrome
MORPHOLOGY, BEHAVIOR, AND THE SONIC HEDGEHOG PATHWAY IN MOUSE MODELS OF DOWN SYNDROME by Tara Dutka A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland July, 2014 © 2014 Tara Dutka All Rights Reserved Abstract Down Syndrome (DS) is caused by a triplication of human chromosome 21 (Hsa21). Ts65Dn, a mouse model of DS, contains a freely segregating extra chromosome consisting of the distal portion of mouse chromosome 16 (Mmu16), a region orthologous to part of Hsa21, and a non-Hsa21 orthologous region of mouse chromosome 17. All individuals with DS display some level of craniofacial dysmorphology, brain structural and functional changes, and cognitive impairment. Ts65Dn recapitulates these features of DS and aspects of each of these traits have been linked in Ts65Dn to a reduced response to Sonic Hedgehog (SHH) in trisomic cells. Dp(16)1Yey is a new mouse model of DS which has a direct duplication of the entire Hsa21 orthologous region of Mmu16. Dp(16)1Yey’s creators found similar behavioral deficits to those seen in Ts65Dn. We performed a quantitative investigation of the skull and brain of Dp(16)1Yey as compared to Ts65Dn and found that DS-like changes to brain and craniofacial morphology were similar in both models. Our results validate examination of the genetic basis for these phenotypes in Dp(16)1Yey mice and the genetic links for these phenotypes previously found in Ts65Dn , i.e., reduced response to SHH. Further, we hypothesized that if all trisomic cells show a reduced response to SHH, then up-regulation of the SHH pathway might ameliorate multiple phenotypes.
