Description
Gender dimorphism exists in the physiological response to diet and other environmental factors. Trans-hydrogenated fatty acid (TFA) intake is associated with an increase in coronary heart disease (CHD), and gender differences in the incidence of CHD are well documented. Neonatal administration of Monosodium Glutamate (MSG) causes stunted heart growth and hypoplasticity; and gender dimorphism at the growth hormone axis has been demonstrated in MSG-treated rodents. The identification of gender dimorphism in cardiac nutrigenomics may provide the basis for gender-specific medicine in the future.

Description
Chronic dietary aspartame may impair rodent insulin tolerance and may affect behavior. Previous studies have shown the aspartame effects may be modulated by developmental NMDA receptor antagonism. Present study was designed to assess effects of aspartame and NMDAR antagonism on components of the HPA axis.

Description
The adult human lung has a very limited capacity to regenerate functional alveoli. In contrast, adult mice have a remarkable capacity for neoalveolarization following either lung resection or injury. The molecular basis for this unique capability to regenerate lung tissue in mice is largely unknown. We examined the transcriptomic responses to single lung pneumonectomy in adult mice in order to elucidate prospective molecular signaling used in this species during lung regeneration. Unilateral left pneumonectomy or sham thoracotomy was performed under general anesthesia (n = 8 mice per group for each of the four time points). Total RNA was isolated from the remaining lung tissue at four time points post-surgery (6 hours, 1 day, 3 days, 7 days) and analyzed using microarray technology. The observed transcriptomic patterns revealed mesenchymal cell signaling, including up-regulation of genes previously associated with activated fibroblasts (Tnfrsf12a, Tnc, Eln, Col3A1), as well as modulation of Igf1-mediated signaling. The data set also revealed early down-regulation of pro-inflammatory cytokine transcripts, up-regulation of genes involved in T cell development and function, but few similarities to transcriptomic patterns observed during embryonic or post-natal lung development. Immunohistochemical analysis suggests that early fibroblast but not myofibroblast proliferation is important during lung regeneration and may explain the preponderance of mesenchymal-associated genes that are over-expressed in this model. This appears to differ from embryonic alveologenesis. These data suggest that modulation of mesenchymal cell signaling and proliferation may act in concert with immunomodulation to control inflammation during post-pneumonectomy lung regeneration in adult mice.

Description
The primary aim of this project was to identify novel factors, in particular the cell-surface protein CD109, which regulate osteoclastogenesis. Microarray analysis was performed comparing two pre-osteoclast cell lines generated from the RAW 264.7 osteoclast cell line: one that has the capacity to fuse forming large multinucleated cells and one that does not fuse. It was found that CD109 was up-regulated by > 17-fold in the osteoclast forming cell line when compared to the cell line that does not fuse.
Publication Title
CD109 plays a role in osteoclastogenesis.

Description
High quality genetic material is an essential pre-requisite when analyzing gene expression using microarray technology. Peripheral blood mononuclear cells (PBMC) are frequently used for genomic analyses, but several factors can affect the integrity of nucleic acids prior to their extraction, including the methods of PBMC collection and isolation. In this study, we compared the Ficoll-Paque density gradient centrifugation and BD Vacutainer cell preparation tube (CPT) protocols to determine if either method offered a distinct advantage in preparation of PBMC-derived immune cell subsets for their use in gene expression analysis. We compared gene expression in PBMC and individual immune cell types from Ficoll and CPT isolation protocols using Affymetrix microarrays.

Description
The translocation t(7;12)(q36;p13) occurs in infants and very young children with AML and usually has a fatal prognosis. Whereas the transcription factor ETV6, located at chromosome 12p13, has largely been studied in different leukemia types, the influence of the translocation partner HB9 (chr. 7q36), is still unknown. This is particularly surprising as ectopic expression of HB9 is the only recurrent molecular hallmark of translocation t(7;12) AML. We investigated the influence of HB9 as a potential oncogene on cell proliferation and cell cycle in vitro, as well as on hematopoietic stem cell differentiation in vivo using murine and human model systems. We show, that HB9 induces premature senescence in human HT1080 and murine NIH3T3 cells, providing for the first time evidence for an oncogenic potential of HB9. Furthermore, HB9-transduced primary murine hematopoietic stem and progenitor cells underwent a profound differentiation arrest and accumulated at the megakaryocyte/erythrocyte progenitor stage, resulting in a premalignant myeloid cell population in vivo. Concomitantly, HB9 expression upregulates erythropoiesis-related genes in primary human hematopoietic stem and progenitor cells, and enriches gene expression profiles for cell cycle and mitosis-related biological processes. In summary, the novel findings of HB9 dependent premature senescence and perturbed hematopoietic differentiation shed light on the oncogenic properties of HB9 in translocation t(7;12) AML and offer novel targets for therapeutic intervention. Overall design: CD34+ cells were transduced with either GFP or HB9

Description
Human and mouse blood each contain two monocyte subsets. Here, we investigated the extent of their similarity using a microarray approach. Approximately 300 genes in human and 550 genes in mouse were differentially expressed between subsets. More than 130 of these gene expression differences were conserved between mouse and human monocyte subsets. We confirmed numerous differences at the cell surface protein level. Despite overall conservation, some molecules were conversely expressed between the two species subsets, including CD36, CD9, and TREM-1. Furthermore, other differences existed, including a prominent PPAR signature in mouse monocytes absent in human. Overall, human and mouse monocyte subsets are far more broadly conserved than currently recognized. Thus, studies in mice may indeed yield relevant information regarding the biology of human monocyte subsets. However, differences between the species deserve consideration in models of human disease studied in the mouse.
