Description
Transcriptional profiling of mouse mesenchymal stem/progenitor cells (MSPC) comparing control Ptpn11+/+ MSPC with Ptpn11E76K/+ MSPC. By obtaining 20 million reads of sequence from two pair, we confirmed our cytokine/chemokine array data and quantitative ELISA data from both mouse and patient-derived specimens. CCL3, CCL12, CCL4, and CXCL12 (SDF-1) were aberrantly produced by Ptpn11 mutated MSPCs Overall design: Examination of mouse Ptpn11E76K/+ mesenchymal stem/progenitor cells (MSPC) transcriptional profiling compared to control Ptpn11+/+ MSPC, freshly isolated from Ptpn11E76K/+/Nestin and Ptpn11+/+/Nestin mice. Two replicate per array.

Description
ZFP36L2, zinc finger protein 36, C3H type-like 2 (also known as Brf2, Erf2, Tis11D) is a member of the tristetraprolin (TTP; Zfp36) family of tandem CCCH zinc finger proteins that can bind to AU-rich elements (AREs) in the 3'-untranslated region of mRNAs, leading to their deadenylation and subsequent degradation. We have generated Zfp36l2 knockout mice. Knockout mice were born at the expected Mendelian frequency, but within several weeks of birth they died rather suddenly with pallor and frequent intestinal hemorrhage. These mice exhibited pancytopenia, decreased hematopoietic progenitor cells from fetal liver and yolk sac, and ineffective hematopoietic stem cells. Since ZFP26L2 is likely to function as an ARE-containing mRNA destabilizing protein, we were interested in identifying any abnormally stabilized transcripts in fetal livers from the Zfp36l2 knockout mice whose protein product may directly or indirectly affect hematopoietic stem cell function.

Description
Human induced pluripotent stem (hiPS) cells and human embryonic stem (hES) cells differentiate into cells of the endothelial lineage, but derivation of cells with human umbilical cord blood endothelial colony forming cell (ECFC)-like properties has not been reported. Here we describe a novel serum- and stromal cell-free ECFC differentiation protocol for the derivation of clinically relevant numbers of ECFCs (> 108) from hiPS and hES cells. We identified NRP-1+CD31+ selected cells that displayed a stable endothelial phenotype exhibiting high clonal proliferative potential, extensive replicative capacity, formation of human vessels that inosculated with host vasculature upon transplantation, but lacking in teratoma formation in vivo. We also identified NRP-1-VEGF165-KDR-mediated activation of KDR as a critical mechanism for the emergence and derivation of ECFCs from hiPS and hES cells. This protocol advances the field by generating highly replicative but stable endothelial cells for use as a potential cell therapy for human clinical disorders. Overall design: Transcriptome sequencing of undifferentiated day 0 hiPS cells, Day 3 differentiated hiPS-derived mesoderm proginator cells, Day 12 hiPS-derived NRP-1+CD31+ cells, Day 12 H9-hES-derived NRP-1+CD31+ cells and cord blood-derived Endothelial colony forming cells.

Description
Purpose: The ability to rationally manipulate the transcriptional states of cells would be of great use in medicine and bioengineering. We have developed a novel algorithm, NetSurgeon, which utilizes genome-wide gene regulatory networks to identify interventions that force a cell toward a desired expression state. Results: We used NetSurgeon to select transcription factor deletions aimed at improving ethanol production in S. cerevisiae cultures that are catabolizing xylose. We reasoned that interventions that move the transcriptional states of cells utilizing xylose toward the fermentative state typical of cells that are producing ethanol rapidly (while utilizing glucose) might improve xylose fermentation. Some of the interventions selected by NetSurgeon successfully promoted a fermentative transcriptional state in the absence of glucose, resulting in strains with a 2.7-fold increase in xylose import rates, a 4-fold improvement in xylose integration into central carbon metabolism, or a 1.3-fold increase in ethanol production rate. Conclusions: We conclude by presenting an integrated model of transcriptional regulation and metabolic flux that will enable future metabolic engineering efforts aimed at improving xylose fermentation to prioritize functional regulators of central carbon metabolism. Overall design: Mutant and wildtype S. cerevisiae cells were put into 48 hour aerobic batch fermentations of synthetic complete medium supplmented with 2% glucose and 5% xylose and culture samples were taken at 4 hours and 24 hours for transcriptional profiling performed by RNA-Seq analysis. In addition, wildtype S. cerevisiae cells were grown in various single carbon sources for 12 hours and culture samples were taken for transcriptional profiling performed by RNA-Seq analysis.

Description
Few studies have investigated heterogeneity of selection response in replicate lines subjected to equivalent selection. We developed 4 replicate lines of mice based on high levels of voluntary wheel running (high runner or HR lines) while also maintaining 4 non-selected control lines. This led to the unexpected discovery of the HR mini-muscle (HRmini) phenotype, recognized by a 50% reduction in hindlimb muscle mass, which became fixed in 1 of the 4 HR selected lines.

Description
While infection of chickens with highly pathogenic avian influenza (HPAI) H5N1 subtypes often leads to complete mortality within 24 to 48 h, infection of ducks in contrast causes mild or no clinical signs. Rapid onsets of fatal disease in chickens, but with no evidence of severe clinical symptoms in ducks, suggest underlying differences in their innate immune mechanisms. To understand the molecular basis for such difference, chicken and duck primary lung cells, infected with a low-pathogenicity avian influenza (LPAI) and two HPAI H5N1 viruses, were subjected to RNA expression profiling using Affymetrix Chicken GeneChip arrays.
Publication Title
Highly pathogenic avian influenza virus infection in chickens but not ducks is associated with elevated host immune and pro-inflammatory responses.

Description
Squamous cell carcinoma (SCC) is the second most common cancer worldwide and accounts for approximately 30% of all keratinocyte cancers. The vast majority of cutaneous SCCs of the head and neck (cSCCHN) are readily curable with surgery and/or radiotherapy unless high-risk features are present. Perineural invasion (PNI) is recognized as one of these high-risk features. The molecular changes during clinical PNI in cSCCHN have not been previously investigated. In this study, we assessed the global gene expression differences between cSCCHN with or without incidental or clinical PNI. The results of the analysis showed signatures of gene expression representative of activation of p53 in tumors with PNI compared to tumors without, amongst other alterations. Immunohistochemical staining of p53 showed cSCCHN with clinical PNI to be more likely to exhibit a diffuse over-expression pattern, with no tumors showing normal p53 staining. DNA sequencing of cSCCHN samples with clinical PNI showed no difference in mutation number or position with samples without PNI, however a significant difference was observed in regulators of p53 degradation, stability and activity. Our results therefore suggest that cSCCHN with clinical PNI may be more likely to contain alterations in the p53 pathway, compared to cSCCHN without PNI.
