Description
Histidine-rich glycoprotein (HRG) is a 75 kDa heparin-binding plasma protein which has been implicated in regulation of tumor angiogenesis and growth. To exert some of its biological functions, HRG acts on macrophages.This study was performed to assess changes in gene expression in peritoneal macrophages treated with HRG using oligonucleotide microarrays
Publication Title
Genetic deficiency in plasma protein HRG enhances tumor growth and metastasis by exacerbating immune escape and vessel abnormalization.

Description
Progression to malignancy requires cells to overcome senescence and switch to an immortal phenotype. Thus, exploring the genetic and epigenetic changes that occur during senescence/immortalization may help elucidate crucial events that lead to cell transformation. In the present study, we have globally profiled DNA methylation in relation to gene expression in primary, senescent and immortalized mouse embryonic fibroblasts.

Description
Alzheimer's disease (AD) is characterized by massive neurodegeneration and multiple changes in cellular processes, including neurogenesis. Proteolytic processing of the amyloid precursor protein (APP) plays a central role in AD. Due to varying APP processing, several beta-amyloid peptides are generated. In contrast to the form with 40 amino acids, the variant with 42 amino acids is thought to be the pathogenic form triggering the pathophysiological cascade in AD. Here, we studied the transcriptomic response to increased or decreased Abeta42 levels generated in human neuroblastoma cells. Genome-wide expression profiles (Affymetrix)were used to analyze the cellular response to the changed Abeta42 and Abeta40-levels. <br></br><br></br>Human neuroblastoma cell line SH-SY5Y is a thrice cloned (SK-N-SH -> SH-SY -> SH-SY5 -> SH-SY5Y) subline of the neuroblastoma cell line SK-N-SH which was isolated and established in 1970. This cell line has 47 chromosomes. The cells possess a unique marker comprised of a chromosome 1 with a complex insertion of an additional copy of a 1q segment into the long arm, resulting in trisomy of 1q. The cell lines used in this study are SHSY5Y transfected with the constructs pCEP-C99I45F, pCEP-C99V50F, pCEP-C99 wildtype or mock transfected with an empty vector. Independent cell clones of each transfected line were used to provide biological replicates.<br></br> Overexpressed C99 I45F is intracellularly cleaved resulting in high Abeta42, but low Abeta40 levels.<br></br> Overexpressed C99V50F is intracellularly cleaved resulting in low Abeta42, but high Abeta40 levels.<br></br>Overexpressed C99 wildtype is intracellularly cleaved resulting in medium Abeta42 and Abeta40 levels<br></br>Mock is the SHSY5Y cell line transfected with the empty vector pCEP (Invitrogen) as a negative control

Description
mDC and pDC exhibit distinct TLR expression pattern and differ in their responses to various TLR ligands. The goal of this study was to identify genes, that were differentally expressed between mDC and pDC as a means to determine how TLR signaling pathways operate. Suprisingly, expression of TLR-assoociated signaling proteins were found to be present at equivalent levels between mDC and pDC, despite differential expression of TLRs, and thus revealing insight into use of adaptor proteins that function as general regulators of TLR signaling pathways in both cell types.

Description
We measured gene expression of D. melanogaster female heads and abdomens after mating with males from six populations evolved under either enforced monogamy (no male-male competition, 3 populations) or sustained polygamy (intense male-male competition, 3 populations). Overall design: Three samples of virgin female heads and six samples of mated female heads (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. Also, three samples of virgin female abdomens and six samples of mated female abdomens (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. In total, eighteen libraries sequenced in 8 lanes.

Description
Beside their role in conventional immune regulation, macrophages are now recognised as essential regulator of local tissue homeostasis depending on the tissue in which they reside. Using phenotyping, we found that LYVE-1+ macrophages are the major resident macrophage population in murine aorta and adipose tissues under steady state. Furthermore, imaging analysis revealed the exclusive association of adipose tissue LYVE-1+ macrophages with smooth muscle positive large blood vessels. Hence, we hypothesize that LYVE-1+ macrophages sustain large vessel functional homeostasis. The present experiment aims to better characterize resident LYVE-1+ vs LYVE-1- macrophages in aorta and adipose tissues. Overall design: LYVE-1+ and LYVE-1- aortic macrophages were FACS sorted as DAPI-CD45+CD64+MerTK+CD11b+F4/80+LYVE-1+ and DAPI-CD45+CD64+MerTK+CD11b+F4/80+LYVE-1- respectively from 30 adult C57/BL6 mice (n =3) their RNA extracted for transcriptome profiling. Similarly, LYVE-1+ and LYVE-1- adipose tissue macrophages were FACS sorted as DAPI-CD45+CD64+MerTK+CD11b+F4/80+LYVE-1+ and DAPI-CD45+CD64+MerTK+CD11b+F4/80+LYVE-1- respectively from 20 adult C57/BL6 epididymal and subcutaneous adipose tissue (n =3) their RNA extracted for transcriptome profiling.

Description
Purpose: In our study, we identified a heterogeneity among bone marrow (BM) Ly6Chi monocytes, which can be subdivided the expression of CXCR4. In order to understand the development of BM monocytes, the goal of this experiment is to compare the transcriptome of these 2 BM Ly6Chi monocyte subsets to those of the common monocyte progenitor (cMoP) and Ly6Clo monocytes. Overall design: 4 BM monocyte subsets (cMoP, Ly6ChiCXCR4hi, Ly6ChiCXCR4lo and Ly6Clo) from 3 different mice were sorted using a BD Aria III. Total RNA was extracted, converted to cDNA and run through deep sequencing using Illumina HiSeq 2500
