Description
Methanol (MeOH) is considered to be a poison in humans because of the alcohol dehydrogenase (ADH)-mediated conversion of MeOH into toxic formaldehyde (FA). Our recent genome-wide analysis of the mouse brain demonstrated that an increase in endogenous MeOH after ADH inhibition led to a significant increase in the plasma MeOH concentration and the modification of mRNA synthesis. These findings suggest endogenous MeOH involvement in homeostasis regulation by controlling mRNA levels. Here, we demonstrate directly that study volunteers displayed increasing concentrations of MeOH and FA in their blood plasma when consuming citrus pectin, ethanol and red wine. A microarray analysis of white blood cells (WBC) in volunteers after pectin intake showed various responses for 30 differentially regulated mRNAs. Most of the mRNAs were somehow involved in the pathogenesis of Alzheimer's disease (AD). There was also a decreased synthesis of hemoglobin mRNA, HBA and HBB, the presence of which in WBC RNA was not a result of red blood cells contamination because erythrocyte-specific marker genes did not show significant change. A qRT-PCR analysis of volunteer WBC after pectin and red wine intake confirmed the complicated dependence between plasma MeOH content and the mRNA accumulation of previously identified genes, namely GAPDH and SNX27, and MME, SORL1, DDIT4, HBA and HBB genes revealed in this study. We hypothesized that human plasma MeOH, which is replenished from endogenous and exogenous sources (diet), has an impact on the WBC mRNA levels of genes involved in AD pathogenesis and signaling.

Illumina Genome Analyzer IIx
Description
RNA-seq was performed using the RNA extracted from the bottom half of right lobe of mouse livers. Mice fall into two groups, mutant group which express ectopic hURI and their control littermates which do not express hURI. Two time points were considered in the study, 1-week-old mice, expressing hURI since 1 week (n =3, 4 for control and mutant, respectively) and 8-week-old mice expressing hURI since 8 week (n= 4, 3 for control and mutant, respectively), as hURI is expressed since conception. Overall design: Determination of differentially expressed transcripts over two time points (1 week and 8 weeks) in mouse livers expressing hURI (1 week and 8 weeks).

Description
Gene expression profile of in vitro differentiated control and CD33 KO CD34+ cells (with 70-85% CD33 KO) were analyzed by RNA-seq to exclude any major impact of CD33 loss on downstream gene expression Overall design: Primary CD34+ cells were treated with CRISPR/Cas9 to disrupt the CD33 gene and grown in culture for 5-7 days prior to analysis; mRNA profile was compared to control cells from the same donor that were also treated with Cas9 and a control gRNA; 5 different donors were evaluated (CD33 KO/control for each = total 10 samples)

Description
Chronic alcohol consumption can lead to alchohol-related brain damage (ARBD). Despite the well known acute effects of alcohol the mechanism responsible for chronic brain damage is largely unknown. Pathologically the major change is the loss of white matter while neuronal loss is mild and restricted to a few areas such as the prefrontal cortex. In order to improve our understanding of ARBD pathogenesis we used microarrays to explore the white matter transcriptome of alcoholics and controls.

Description
Damage-associated molecular pattern (DAMP) molecules S100A8 and S100A9 with well-known functions in inflammation, tumor growth and metastasis. It has been found to have promote tumor cell proliferation activity at low concentration . However, the mechanism underlying this remains unclear. In the current study, we performed genome expression profiling analysis using the Affymetrix genome wide microarray system to identify broad scale changes in gene expression associated with S100a8 or S100a9 recombinant protein stimulation in murine colon carcinoma cell line CT26.WT.

Description
Tcf1 is necessary for optimal T lineage development. Tcf1 deficient progenitors fail to initiate the T lineage program in vitro and development is severely defective in vivo. We used microarrays to assess the overal global gene expression differences from Tcf1 wildtype and deficient lymphoid biased progenitors cultures on Notch-ligand expressing stroma to determine if Tcf1 deficient progenitors are able to intiate the T lineage specification program.

Description
We used microarrays to perform a global gene expression analysis in Tcf1-expressing Thy1+CD25+ T lineage cells that develop on OP9 stroma in the absence of Notch1 signals. We compare this to the starting population, LMPP progenitors, and to control expressing T lineage cells that developed on OP9 stroma expressing Notch ligand DL4. The overall goal of this study was to determine if Tcf1 initiates T lineage specification in lymphoid progenitors. We found that Tcf1 was sufficient to upregulate many T lineage genes as compared to control expressing progenitors on OP9-DL4.
