Description
Paired platinum-sensitive & platinum-resistant cell lines PEO1 and PEO4 (respectively) were derived from the same patient. Cell line cultures were profiled with the HT-HGU133a GeneChip to investigate chemotherapy resistance related expression of genes marked with different histone modifications in a primary ovarian tumour (clinical data for the primary ovarian tumour is available as Series supplementary file).

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Myeloid derived suppressor cells (MDSC) playing the immune suppressive roles in tumor bearing host consists of two major subsets of granulocytic and monocytic cells. Granulocytic MDSC (G-MDSC) express CD11b+ Gr-1high Ly6G+ Ly6Clow and produce high level of reactive oxygen species (ROS). Interestingly, neutrophils are well known ROS producing cells during immune defensive process and share same surface markers with G-MDSC. These similar features always brought the fundamental questions whats the difference between G-MDSC and neutrophils but its not yet proven clearly.
Publication Title
Characterization of the nature of granulocytic myeloid-derived suppressor cells in tumor-bearing mice.

Description
Dendritic cells (DC) arise from a diverse group of hematopoietic progenitors and have marked phenotypic and functional heterogeneity. We have found previously that activation of protein kinase C beta 2 (PRKCB2) by cytokines or phorbol esters drives normal human CD34(+) hematopoietic progenitors and myeloid leukemic blasts (KG1, K562 cell lines, and primary patient blasts) to differentiate into DC, but the genetic program triggered by PRKCB2 activation that results in DC differentiation is only beginning to be characterized. Of the cPKC isoforms, only PRKCB2 was consistently activated by DC differentiation-inducing stimuli in normal and leukemic progenitors. To examine early changes in gene expression following PRKCB2 activation, we employed the following cell lines: (1) the CD34(+) human acute myeloid leukemia derived cell line KG1, which undergoes DC differentiation following phorbol ester treatment; (2) KG1a, a spontaneously arising differentiation-resistant daughter cell line of KG1 that has lost PRKCB2 expression; (3) clones established from KG1a that stably express exogenous PRKCB2-GFP fusion proteins and are once again able to undergo DC differentiation (KG1a-PRKCB2-GFP Clone E9 and Clone E11). We examined changes in gene expression in these cells following treatment with the phorbol ester PMA (phorbol 12-myristate 13-acetate) for 2 hours. Since KG1 and KG1a differ in PRKCB2 expression but have similar expression of the other protein kinase C isoforms, this protocol will allow for the identification of genes regulated by PRKCB2 activation.

Illumina HiSeq 2500
Description
We analyzed the global effect of c-Myb knockdown by sequencing the transcriptomes of K-562 cells transfected with control siRNA and si2992 (MYB knockdown), as well as K-562 cells stably expressing TY-tagged wild type c-Myb and c-Myb D152V transfected with si2992 Overall design: Cells were tranfected with siRNA and 24 hours after total RNA was extracted. Three individual experiments were performed. Libraries were prepared and 125-bp paired-end reads were obtained using an Illumina HiSeq 2500 sequencer
Publication Title
A c-Myb mutant causes deregulated differentiation due to impaired histone binding and abrogated pioneer factor function.

- Affymetrix Plasmodium/Anopheles Genome Array (plasmodiumanopheles)
Description
In the present study, we have investigated the effect of CpG Oligodeoxynucleotides (CpG-ODN) on the outcome of Plasmodium infection of the mosquito vectors Anopheles stephensi and Anopheles gambiae and on the modulation of mosquito immunity to Plasmodium. Anopheles mosquitoes inoculated with CpG-ODN showed significant reduction of Plasmodium infection rate and intensity. Microarrays were used to profile transcription of fat-body from CpG-ODN-treated mosquitoes. Mosquitoes were dissected 18h after ODN inoculation (immediately before feeding). Batches of 20 to 30 fat bodies (abdomen without midgut, ovaries and malpighian tubule]) were dissected in cold DEPC-treated phosphate-buffered saline (PBS) and processed for RNA preparation. Mosquitoes treated with CpG-ODNs are less susceptible to Plasmodium infection. Transcription profile of fat body indicates that protection was associated with coagulation/wound healing, while melanization appears to be depressed.
