Description
Background: In this study we reveal a previously undescribed role of the HACE1 (HECT domain and Ankyrin repeat Containing E3 ubiquitin-protein ligase 1) tumor suppressor protein in normal vertebrate heart development using the zebrafish (Danio rerio) model. We examined the link between the cardiac phenotypes associated with hace1 loss of function to the expression of the Rho small family GTPase, rac1, which is a known target of HACE1 and promotes ROS production via its interaction with NADPH oxidase holoenzymes. We examined expression changes induced by knock-down of hace1 in zebrafish at 48 hpf, the stage when heart abnormalities are observed. This was done by collecting duplicate samples of control and hace1 morphant embryos and performing RNA sequencing on them. Conclusions: Our study demonstrates that HACE1 is critical in the normal development and proper function of the heart via a ROS-dependent mechanism. Overall design: 2 samples of control and hace1 morphant zebrafish embryos at 48 hpf were analyzed

- Affymetrix Human Exon 1.0 ST Array [probe set (exon) version (huex10st)
Description
YB-1 controls epithelial-mesenchymal transitions by restricting translation of growth-related mRNAs and enabling expression of EMT-inducing transcription factors. We used microarrays to characterize the direct transcriptional and indirect translational regulation of mRNAs by exogenous YB-1 in breast cancer cell lines.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Low oxygen stress dynamically regulates the translation of cellular mRNAs as a means of energy conservation in seedlings of Arabidopsis thaliana. Most of the highly hypoxia-induced mRNAs are recruited to polysomes and actively translated, whereas other cellular mRNAs become translationally inactive and are either targeted for stabilization or degradation. Here we identify the involvement of OLIGOURIDYLATE BINDING PROTEIN 1 (UBP1), a triple RNA Recognition Motif protein, in dynamic and reversible aggregation of translationally repressed mRNAs during hypoxia. Mutation or downregulation of UBP1C interferes with seedling establishment and reduces survival of low oxygen stress. By use of messenger ribonucleoprotein immunopurification, we show that UBP1C constitutively binds a subpopulation of mRNAs characterized by U-rich 3-untranslated regions under normoxic conditions. During hypoxia, UBP1C association with non-U-rich mRNAs is enhanced concomitant with its aggregation into microscopically visible cytoplasmic foci, referred to as UBP1 stress granules (SGs). This UBP1C-mRNA association occurs as global levels of protein synthesis decline. Upon reoxygenation, rapid UBP1 SG disaggregation coincides with the return of the stabilized mRNAs to polysomes. The mRNAs that are highly induced and translated during hypoxia largely circumvent UBP1C sequestration. Thus, UBP1 is established as a component of dynamically assembled cytoplasmic mRNPs that sequester mRNAs that are poorly translated during a transient low energy stress.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Regulator of sex-limitation (rsl) is a recessive mouse phenotype in which the otherwise male-specific sex-limited protein (Slp) gene is expressed in females. Positional cloning in rsl mice led to the identification of mutations in two neighboring KRAB zinc finger transcriptional repressors, Rsl1 and Rsl2, and BAC transgenic rescue experiements verified their ability to repress male-specific genes in the liver.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We report a mouse model that recapitulates expression of the ETV6-NTRK3 (EN) fusion oncoprotein, the product of the t(12;15)(p13;q25) translocation characteristic of human secretory breast carcinoma. Activation of EN expression in mammary tissues by Whey acidic protein (Wap) promoter-driven Cre leads to fully penetrant, multifocal malignant breast cancer with short latency. We provide genetic evidence that committed bipotent or CD61+ luminal alveolar progenitors, are targets of tumorigenesis. Furthermore, EN transforms these otherwise transient progenitors through activation of the AP1 complex. Given increasing relevance of chromosomal translocations in epithelial cancers, such mice serve as a paradigm for the study of their genetic pathogenesis and cellular origins, and generation of novel preclinical models.
