Description
The purpose of current study is to identify the differentiated gene expression associated with mouse 11B3 deletion, syntenic to human chromosome 17p13.1. We compared four different mouse acute myeloid leukemia cells, freshly isolated from mouse bone marrows with either 11B3fl/p53fl;shNf1;shMll3;Vav1-Cre or p53fl/fl;shNf1;shMll3;Vav1-Cre. The RNA-seq results indicate that genes located on chromosome 11B3 mostly reduce gene expression level in 11B3 deleted leukemia cells. Overall design: Examination RNA expression level in 11B3-deleted vs p53-loss only samples.

Description
Heart formation requires the fusion of bilateral cardiomyocyte populations as they move toward the embryonic midline. The bHLH transcription factor Hand2 is essential for cardiac fusion; however, the effector genes that execute this function of Hand2 are unknown. Here, we provide the first evidence for a downstream component of the Hand2 pathway that mediates cardiac morphogenesis. Although hand2 is expressed in cardiomyocytes, mosaic analysis demonstrates that hand2 plays a non-autonomous role in regulating cardiomyocyte movement. Gene expression profiles reveal heightened expression of fibronectin 1 (fn1) in hand2 mutant embryos. Reciprocally, overexpression of hand2 leads to decreased Fibronectin levels. Furthermore, reduction of fn1 function enables rescue of cardiac fusion in hand2 mutants: bilateral cardiomyocyte populations merge and exhibit improved tissue architecture, albeit without major changes in apicobasal polarity. Together, our data provide a novel example of a tissue creating a favorable environment for its morphogenesis: the Hand2 pathway establishes an appropriate environment for cardiac fusion through negative modulation of Fn1 levels.
Publication Title
Hand2 ensures an appropriate environment for cardiac fusion by limiting Fibronectin function.

Description
Engineering microbes with novel metabolic properties is a critical step for production of biofuels and biochemicals. Synthetic biology enables identification and engineering of metabolic pathways into microbes; however, knowledge of how to reroute cellular regulatory signals and metabolic flux remains lacking. Here we used network analysis of multi-omic data to dissect the mechanism of anaerobic xylose fermentation, a trait important for biochemical production from plant lignocellulose. We compared transcriptomic, proteomic, and phosphoproteomic differences across a series of strains evolved to ferment xylose under various conditions. Overall design: RNA-seq and transcriptome analysis of three evolved S. cerevisiae strains (Y22-3, Y127, Y128) grown aerobically or anaerobically in rich lab media with glucose, xylose, galactose, or sorbitol. Duplicates were collected on different days.

Description
Microarray analysis has been applied to the cell proliferation in a human colonic cel line, Caco-2. We have shown previously that a moderate riboflavin depletion around weaning has a profound impact on the structure and function of the small intestine of the rat, which is not reversible following riboflavin repletion. In this study we have modelled riboflavin deficiency in a human cell line, shown irreversible loss of cell viability associated with impaired mitosis and identified candidate effectors of riboflavin depletion in the cell.

Description
Grainyhead genes are involved in wound healing and developmental neural tube closure. In light of the high degree of similarity between the epithelial-mesenchymal transitions (EMTs) occurring in wound healing processes and the cancer stem cell-like compartment of tumors, including TGF--dependence, we investigated the role of a Grainyhead gene (GRHL2) in oncogenic EMT. Grainyhead was specifically down-regulated in the claudin-low subclass of mammary tumors and in the basal-B subclass of breast cancer cell lines. Functionally, GRHL2 suppressed TGF--induced, Twist-induced or spontaneous EMT, enhanced anoikis-sensitivity, and suppressed mammosphere generation in mammary epithelial cells. These effects were mediated, in part, by its suppression of ZEB1 expression, through direct repression of the ZEB1 promoter. GRHL2 also inhibited Smad-mediated transcription, and up-regulated mir200b/c as well as the TGF- receptor antagonist, BMP2. The expression of GRHL2 in the breast cancer cell line MDA-MB-231 triggered a mesenchymal-to-epithelial transition and sensitized the cells to anoikis. These results indicate that GRHL2 is a suppressor of the oncogenic EMT.
