Candidatus Liberibacter asiaticus infection of citrus is characterized by symptom variability within and among organs. In order to identify molecular processes involved in the regulation of organ response to Ca. Liberibacter infection, the gene expression patterns in C. sinensis leaf, stem, and root was examined in Affymetrix microarray.

Dual actions of Meis1 inhibit erythroid progenitor development and sustain general hematopoietic cell proliferation.

View SamplesThe homeodomain protein Meis1 is essential for definitive hematopoiesis and vascular patterning in the mouse embryo. Meis2, another member of the same family, shares 82% protein identities with Meis1. Our present study suggested Meis2 exerts two distinguishable effects in differentiating ES cells. First, it increases the numbers of hematopoietic progenitors and extends their persistence in culture. Second, Meis2 skews hematopoietic differentiation by suppressing erythroid while enhancing megakaryocytic progenitor differentiation. To identify the underlying transcriptional bases of these actions, we carried out microarray analysis to compare the various populations of cells developing in ES differentiation cultures in the presence and absence of Meis2 induction.

View SamplesPreviously, we reported that the transcription factor Mesp1 promotes the cell fates of cardiomyocytes, smooth muscle, and vascular endothelium. Recently, hematopoietic stem cells (HSCs) were shown to derive from hemogenic endothelium. Since Mesp1 regulates development of endothelium, it potentially could influence gene expression related to hematopoietic development.

Systems genetics identifies a co-regulated module of liver microRNAs associated with plasma LDL cholesterol in murine diet-induced dyslipidemia.

View SamplesGenetic variation, in addition to environmental influences like diet, can govern the expression levels of microRNAs (miRNAs). MiRNAs are commonly found to operate cooperatively in groups to regulate gene expression. To investigate this, we combined small RNA sequencing, clinical phenotypes, and microarray data measuring gene expression from an outbred mouse model, the Diversity Outbred population. In the DO population, each individual has a distinct genome that is a mosaic of 8 inbred founder strains. We used these data to identify co-regulated modules of miRNAs and genes that are influenced by genetics and diet, and identify relationships between the modules and phenotypes in over 200 DO mice.
