ABSTRACT: Monkeypox virus: Genome sequencing by Pathogen Genomic Lab, Institut National de Recherche Biomédicale, Kinshasa, Democratic Republic of the Congo
Project description:Maternal stress has long been associated with lower birthweight but mechanisms remain elusive. This study explored how maternal stress may impact changes in gene expression within a cohort of mother-placenta-newborn triads in the eastern Democratic Republic of Congo We used microarrays to detail the global programme of gene expression underlying the impact of maternal stress on newborn birthweight and identified that global placental gene expression may partially mediate the negative impact of maternal war stress on newborn birthweight.
Project description:The purpose of this experiment was to obtain samples for mRNA analysis in IHH cells infected with Zaire Ebola virus and mutants: Zaire Ebola virus: This wild-type Ebola virus - strain Mayinga - was isolated from a fatal human case in Zaire (now known as the Democratic Republic of Congo) in 1976 Zaire Ebola virus, VP35 R312A possesses a R312A mutation in the VP35 protein. Zaire Ebola virus, delta sGP. Lacks the ability to produce non-structural protein, the secreted glycoprotein (sGP). Zaire Ebola virus, delta mucin. Lacks the mucin-like domain (MLD), which contains both N-linked and O-linked glycosylation sites, for the glycoproteins.

Project description:Genome-wide DNA methylation profiling of venous blood samples from children in the Eastern Democratic Republic of Congo from birth to age three. DNA methylation data were noob normalized and uploaded to Steve Horvath's epigenetic age calculator website to calculate Horvath epigenetic age acceleration for each participant at each timepoint for which they had data available. Replicates were averaged and a single outlier at birth was removed as described in the manuscript, leaving 155 observations from 67 unique individuals. Sample size at each timepoint was as follows: n = 64 at birth, n = 8 at six months, n= 35 at one year, n = 32 at two years, and n = 16 at three years.
Project description:Orthopox viruses, including monkeypox, multiply intracellularly and induce numerous changes in host genes expression. The virus target mainly humoral host response, and simultaneously, exploits other genes and functions to reproduce effectively. The goal of this experiment is to identify those host genes and functions that are essential for monkeypox virus replication. Mock infected control cells were treated and incubated identically to time point arms, except for virus exposure. Two time points of cells infected with monkeypox virus were harvested at 3, 7 hours post infection, and gene expression was assessed using microarray in all arms. The experiment was done in triplicate.

Overview of Experiment: Cells: Immortalized Human Hepatocytes (IHH); seed 60,000 cells per well in a 24-well plate. Infected with a multiplicity of infection (MOI) of 0.5. After infection, 3x wash with PBS and replace with 5% FCS DMEM without NaPyr or NEAA. Time matched mocks done in triplicate from same cell stock as rest of samples. Time Points = 0, 6, 12, 24, 48, and 72 hrs post infection in triplicate.
