Description
We sought to determine the genes regulated by the Drosophila Hox protein AbdA in a homogenous cell system. S2-DRSC cells that have no Hox expression were stably transfected with HA-tagged AbdA under the control of a metallothionein promoter. Overall design: S2-DRSC cells are stably transfected with HA-tagged AbdA (S2-DRSC:AbdA). S2 and S2-AbdA cells are analysed for gene expression in the absence (S2-DRSC) and presence (S2-DRSC-HA::AbdA) of AbdA

Description
Based on the results of numerous clinical and preclinical analyses, the transcription factor HIF-1a has been identified as an important tumor-promoting factor and is considered to be an attractive target for cancer therapy. To further deconstruct the molecular nature of HIF-1as role in tumorigenesis, we have applied lentiviral shRNA transduction to establish HIF-1a-deficient gastric cancer cells. Interestingly, functional analyses failed to show a significant growth defect of HIF-1a-deficient gastric cancer cells in vitro and in vivo. These observations led us to propose that stable inactivation of HIF-1a resulted in efficient compensation enabling cell growth and, ultimately, tumor progression in a HIF-1a-independent manner. To better understand the mechanisms that control this compensation, we performed transcriptomics of control (scrambled (SCR)) and HIF-1a-deficient (HIF) gastric cancer cells.

Description
Quiescent and dividing hemopoietic stem cells (HSC) display marked differences in their ability to move between the peripheral circulation and the bone marrow. Specifically, long-term engraftment potential predominantly resides in the quiescent HSC subfraction, and G-CSF mobilization results in the preferential accumulation of quiescent HSC in the periphery. In contrast, stem cells from chronic myeloid leukemia (CML) patients display a constitutive presence in the circulation. To understand the molecular basis for this, we have used microarray technology to analyze the transcriptional differences between dividing and quiescent, normal, and CML-derived CD34+ cells.

Description
The comparative whole genome transcriptome effects of two similar pharmaceuticals, imig or vela, on a Gaucher disease mouse model, 9V/null, were evaluated by two commonly used platforms, mRNA-Seq and microarray. Also, statistical methods, DESeq and edgeR for mRNA-Seq and Mixed Model ANOVA for microarray, were compared for differential gene expression detection. The biological pathways were similar between two platforms. Cell growth and proliferation, cell cycle, heme metabolism, and mitochondrial dysfunction were the most altered functions associated with the disease process. Although the two biopharmaceuticals have a very similar structure and function, imig- and vela- treatment in the mice differentially affected disease-specific pathways indicating the action of the two drugs on the disease process in the visceral tissues of Gaucher mouse model differ significantly at the molecular level. This study provides a comprehensive comparison between the two platforms (mRNA-Seq and microarray) for gene expression analysis and addresses the contribution of the different methods involved in the analysis of such data. The results also provide insights into the differential molecular effects of two similar biopharmaceuticals for Gaucher disease treatment Overall design: 9V/null mice (Gaucher mouse model) were injected weekly via tail vein with 60U/kg/wk of imig or vela for 8 wks. Control 9V/null mice were injected with same volume of saline. Wt mice were untreated. Age and strain matched mice were used for the study. Also, statistical methods, DESeq and edgeR for mRNA-Seq and Mixed Model ANOVA for microarray, were compared for differential gene expression detection. Cell growth and proliferation, cell cycle, heme metabolism, and mitochondrial dysfunction were the most altered functions associated with the disease process.

Description
Gaucher disease type 1 is an inborn error of metabolic disease with the defective activity of the lysosomal enzyme acid b-glucosidase (GCase). Enzyme replacement/reconstitution therapy (ERT), infusions with purified recombinant GCases, is efficacious in reversing hematologic, hepatic, splenic, and bony disease manifestations in Gaucher type 1 patients. However, the tissue specific molecular events in Gaucher disease and their response to therapy are not known yet. To explore the molecular events underlying GCase treatment, we evaluated the tissue-specific gene expression profiles and molecular responses in our Gaucher disease mouse model, which were treated with two FDA approved commercially available GCases, imiglucerase (imig) and velaglucerase alfa (vela). Using microarray and mRNA-Seq techniques, differentially expressed genes (DEGs) were identified in the spleen and liver by the direct comparison of imig- vs. vela- treated mice. Among them three gene expression networks were derived from these spleens: 1) cell division/proliferation, 2) hematopoietic system and 3) inflammatory/macrophage response. Our study showed the occurrence of differential molecular pathophysiologic processes in the mice treated with imig compared with vela even though these two biosimilars had the same histological and biochemical efficacy Overall design: 9V/null mice (Gaucher mouse model) were injected weekly via tail vein with 60U/kg/wk of imig or vela for 8 wks. To understand the molecular events underlying GCase treatment, we evaluated the tissue-specific gene expression profiles and molecular responses in our Gaucher disease mouse model, which were treated with two FDA approved commercially available GCases, imiglucerase (imig) and velaglucerase alfa (vela).

Description
Purpose: The aim of this study is to determine the relative expresson levels of mRNA transcripts in wild type platelets Methods: Total RNA was extracted and purified from purified platelets from BALB/c male mice (3 independent samples). Platelet purification was performed as described in Josefsson EC et al, Journal of Experimental Medicine (2011) 208:2017-31. Total RNA (100 ng) was used to generate sequencing libraries for whole transcriptome analysis following Illumina’s TruSeq RNA v2 sample preparation protocol. Completed libraries were sequenced on HiSeq 2000 with TruSeq SBS Kit v3- HS reagents (Illumina) as 100 bp paired-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Reads were aligned to the mouse reference genome mm10 and counts for known genes were obtained using the Rsubread package (version 1.18.0) (Liao et al. 2013; Liao et al. 2014). Overall design: Total RNA was extracted and purified from purified platelets from BALB/c male mice (3 independent samples per population).
