More than 50% of prostate tumors have a chromosomal rearrangement resulting in aberrant expression of an oncogenic ETS family transcription factor. However, mechanisms that differentiate the function of oncogenic ETS factors expressed in prostate tumors from non-oncogenic ETS factors expressed in normal prostate are unknown. Here, we find that four oncogenic ETS (ERG, ETV1, ETV4, and ETV5), and no other ETS, interact with the Ewing's sarcoma breakpoint protein, EWS. This EWS interaction was necessary and sufficient for oncogenic ETS functions including gene activation, cell migration, clonogenic survival, and transformation...

Chromosomal rearrangements deregulating hematopoietic transcription factors are common in acute lymphoblastic leukemia (ALL). Here we show that deregulation of the homeobox transcription factor gene DUX4 and the ETS transcription factor gene ERG is a hallmark of a subtype of B-progenitor ALL that comprises up to 7% of B-ALL. DUX4 rearrangement and overexpression was present in all cases and was accompanied by transcriptional deregulation of ERG, expression of a novel ERG isoform, ERGalt, and frequent ERG deletion...

A translocation leading to the formation of an oncogenic EWS-ETS fusion protein defines Ewing sarcoma. The most frequent gene fusion, present in 85 percent of Ewing sarcomas, is EWS-FLI1. Here, a high-throughput RNA interference screen was performed to identify genes whose function is critical for EWS-FLI1 driven cell viability. In total, 6781 genes were targeted by siRNA molecules and the screen was performed both in presence and absence of doxycycline-inducible expression of the EWS-FLI1 shRNA in A673/TR/shEF Ewing sarcoma cells...

BACKGROUND: Ectopic pregnancy (EP) has been reported to occur in 1.4-5.4% of all clinical pregnancies resulting from in vitro fertilization (IVF) and embryo transfer (ET). Data on factors associated with abnormal embryo implantation following assisted conception are limited. MATERIALS AND METHODS: A systematic review and meta-analysis was performed to determine whether there is an association between the day (cleavage-stage, D3, versus blastocyst, D5) or the type (fresh versus frozen/thawed) of ET and EP rate...

The ion exchange of yttrium, one of the five most critical rare-earth elements as outlined by the U.S. Department of Energy, into ETS-4 is a dynamic, multistep ion exchange process. The ion exchange process was followed using in situ time-resolved Raman spectroscopy, and the crystal structures of the pre-exchange and post-exchange forms were determined by single-crystal X-ray diffraction. In situ Raman spectroscopy is an ideal tool for this type of study, as it measures the spectral changes that are a result of molecular geometry changes at fast time intervals, even where symmetry and unit volume changes are minimally detected by X-ray diffraction...

Smoking is the leading cause of avoidable death and is associated with type 2 diabetes (T2D) risk. Previous studies on the impact of passive smoking have not been applied to a Hispanic-majority population. We investigated the association between active smoking, exposure to environmental tobacco smoke (ETS), and pre-diabetes risk in a New Mexico population. We hypothesized that pre-diabetes risk increases with increasing smoking status after adjustment for important covariates. We screened 219 adults from an ongoing study who were categorized according to their smoking status (never smoker, current smoker, previous smoker) and their exposure to ETS (exposed or unexposed)...

OBJECTIVE: Exposure to environmental tobacco smoke (ETS) in smoky venues puts patrons and employees at risk for immediate respiratory symptoms. Although much literature focuses on outcomes associated with chronic ETS exposure, the current study assesses changes in lung function after acute exposure. METHODS: Ninety-six nonsmoking, healthy adults were exposed to ETS at a bar. Lung function [eg, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1)] was assessed at baseline, immediately after 3 hours of ETS exposure, and 2 hours after exiting the bar...

Obesity is a global health issue, arousing interest in molecular mechanisms controlling fat. Transcriptional regulation of fat has received much attention, and key transcription factors involved in lipid metabolism, such as SBP-1/SREBP, LPD-2/C/EBP, and MDT-15, are conserved from nematodes to mammals. However, there is a growing awareness that lipid metabolism can also be controlled by post-transcriptional mechanisms. Here, we show that the Caenorhabditis elegans RNase, REGE-1, related to MCPIP1/Zc3h12a/Regnase-1, a key regulator of mammalian innate immunity, promotes accumulation of body fat...

The transcription factor Ets-1 is involved in various physiological processes and invasive pathologies. Human Ets-1 exists under three isoforms: p51, the predominant full-length isoform, p42 and p27, shorter alternatively spliced isoforms. We have previously demonstrated that Ets-1 p51, but not the spliced variant Ets-1 p42, is processed by caspases in vitro and during apoptosis. However, the caspase cleavage of the second spliced variant Ets-1 p27 remains to investigate. In the present study, we demonstrate that Ets-1 p27 is a cleavage substrate of caspases...

We examined the correlation between the odor concentration and the chemical composition of environmental tobacco smoke (ETS). Three types of ETS samples were prepared: secondhand smoke (SHS), thirdhand smoke (THS), and field ETS samples from an outside smoking area. The odor concentrations of the ETS, SHS, and THS samples were determined by the triangle-odor-bag method, and the chemical compositions were determined by proton transfer mass spectrometry. The odor concentration of the SHS samples was three or four orders of magnitude higher than that of the field ETS samples, and three orders of magnitude higher than that of the THS samples...
