Description
Here we show that in MMTV-Myc cells (1) MS culture enriches for aggressive breast cancer cells compared to the bulk cells, (2) Cbx8 knockdown reduces Notch-network gene expression. Overall design: Gene expression of (1) bulk vs MS MMTV-Myc cells, (2) control vs Cbx8 knockdown MMTV-Myc cells

Description
Preeclampsia complicates more than 3% of all pregnancies in the United States and Europe. High-risk populations include women with diabetes, dyslipidemia, thrombotic disorders, hyperhomocysteinemia, hypertension, renal diseases, previous preeclampsia, twin pregnancies, and low socioeconomic status. In the latter case, the incidence may increase to 20% to 25%. Preeclampsia is a major cause of maternal and fetal morbidity and mortality. Preeclampsia is defined by systolic blood pressure of more than 140 mm Hg and diastolic blood pressure of more than 90 mm Hg after 20 weeks gestation in a previously normotensive patient, and new-onset proteinuria. Abnormal placentation associated with shallow trophoblast invasion (fetal cells from outer cell layer of the blastocyst) into endometrium (decidua) and improper spiral artery remodeling in the decidua are initial pathological steps.

Description
We compared the gene expression of A549 cells following 24 and 48 hours of treatment with a no-observed-effect level dose of cisplatin. The objective of the study is to identify genes that are differentially expressed in response to sub-lethal doses of cisplatin. This study helps identify not only treatment responses but also changes in gene expression that may confer cytoprotective mechanisms that allow these cells to survive treatment and to develop treatment resistance.
Publication Title
Combined Use of Gene Expression Modeling and siRNA Screening Identifies Genes and Pathways Which Enhance the Activity of Cisplatin When Added at No Effect Levels to Non-Small Cell Lung Cancer Cells In Vitro.

Description
Purpose: Here we demonstrate ALK3Bright/PDX1+ cells residing within the human pancreatic ducts have progenitor like characteristics. Using flow cytometery, live-cell sorting of ALK3bright/PDX1+ cells is possible using a surrogate surface marker for PDX1 (P2RY1). Treating ALK3bright/P2RY1+ cells with BMP7 results in their expansion. Later removal of BMP7 results in the differentiation of these cells to ß-like cells. Here we compare the mRNA expression profiles of these three different cell types (in triplicate). Methods: mRNA profiles of ALK3Bright/P2RY1+ cells isolated from human non-endocrine pancreatic tissue, ALK3Bright/P2RY1+ cells treated with BMP7 and ALK3Bright/P2RY1+ cells differentiated to ß-like cells after BMP7 removal were generated by deep sequencing, in triplicate, using Illumina HiSeq PE Cluster Kit v4 and Illumina HiSeq Flow Cell v4 with 50 nt paired end reads plus dual index reads using the Illumina HiSeq SBS kit v4. Sequence reads that passed quality filters were analyzed at the transcript isoform level following alignment using TopHat v2.1.0 followed by exon and gene level counting using Bioconductor easyRNASeq v 2.4.7. Conclusions: Our study represents the first detailed analysis of ALK3Bright/P2RY1+ sorted cells with biological replicates. We demonstrate ALK3Bright/P2RY1+ cells were shown to form progenitor-like epithelial colonies characterized by NKX6.1 and PDX1 expression. Unlike the negative fraction controls, these colonies responded to BMP-7 by generating new ß-like cells as well as cells from other pancreatic lineages. The transcriptional profile of these cells and their BMP7 treated counterparts suggest a mitotic and progenitor like state. Our studies confirm the progenitor-like nature of ALK3Bright/PDX1+ cells within the human pancreas and suggest a specific anatomical location within the ductal network. Overall design: Comparison of transcriptional expression in Alk3Bright/P2RY1+ cells, Alk3Bright/P2RY1+ cells treated with BMP7 and Alk3Bright/P2RY1+ cells allowed to differentiate after BMP7 removal. Human islets, isolated from the same donors were included as a control.
