Description
Heart failure is a leading cause of mortality and morbidity in the developed world, partly because mammals lack the ability to regenerate heart tissue. Whether this is due to evolutionary loss of regenerative mechanisms present in other organisms or to an inability to activate such mechanisms is currently unclear. Here, we decipher mechanisms underlying heart regeneration in adult zebrafish and show that the molecular regulators of this response are conserved in mammals. We identified miR-99/100 and Let-7a/c, and their protein targets smarca5 and fntb, as critical regulators of cardiomyocyte dedifferentiation and heart regeneration in zebrafish. Although human and murine adult cardiomyocytes fail to elicit an endogenous regenerative response following myocardial infarction, we show that in vivo manipulation of this molecular machinery in mice results in cardiomyocyte dedifferentiation and improved heart functionality after injury. These data provide a proof-of-concept for identifying and activating conserved molecular programs to regenerate the damaged heart. Overall design: RNA-Seq expression profiles of rat cardiomyocytes after knockdown of miR-99/100 and Let-7 miRNAs

Description
To determine effects of p53 activation on levels of RNA associated with polysomes, we performed RNA-seq analysis of colorectal carcinoma cell line HCT116, breast carcinoma line MCF7, and osteosarcoma line SJSA treated with MDM2 inhibitor Nutlin. Overall design: Polysomal RNA was extracted from HCT116, MCF7 and SJSA cells treated with Nutlin, polyA enriched and subjected to RNA-seq protocol.

Description
HCT116 colon carcinoma cells invade more the basement membrane when carcinoma-associated fibroblasts (CAFs) are present. In order to identify if CAFs induce an invasive phenotype to HCT116 cells, and therefore regulate genes expression related to invasion, we compared gene expression of HCT116 cells cultured alone or in the presence of CAFs.

Cancer-associated fibroblasts induce metalloprotease-independent cancer cell invasion of the basement membrane.

Description
TCP transcription factors from the CYC2-class are involved in the development of monosymmetric flowers in all core eudicot species analysed so far. In Antirrhinum majus, the CYC2/TCP transcription factor CYCLOIDEA (CYC) is the molecular key regulator driving the development of flower monosymmetry (Luo D, Carpenter R, Vincent C, Copsey L, Coen E: Origin of floral asymmetry in Antirrhinum. Nature 1996, 383:794-799). In the Brassicaceae Iberis amara, a stronger expression of the CYC2 gene IaTCP1 in the small adaxial petals likely leads to the reduced petal size in comparison to large abaxial petals, with hardly any IaTCP1 expression. This results in the formation of the monosymmetric Iberis flower (Busch A, Zachgo S: Control of corolla monosymmetry in the Brassicaceae Iberis amara. PNAS 2007, 104:16714-16719). In contrast, the orthologous TCP/CYC2 transcription factor TCP1 from Arabidopsis thaliana, which forms equally sized and shaped petal pairs, only shows an early and transient expression in the adaxial area of floral primordia. This implies that monosymmetry in the Brassicaceae evolved through a heterochronic expression shift of the TCP/CYC2 key regulator gene IaTCP1.

Over activation of the aryl hydrocarbon receptor (AhR) by TCDD results ampng other phenotypes in severe thymic atrophy accompanied by immunosuppression. The link between thymic atrophy, skewed thymocyte differntiation and immunosuppression is still not fully resolved. This study investigates the TCDD elicted exprssion changes in the ET, cortical thymus epithelial cell line.

Dose-dependent femoral gene expression was examined following repeated exposure (every 4 days for 28 days) to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). These data were used to examine the effect of repeated TCDD exposure on gene expression in the femur of C57BL/6 male mice.
