Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Aims: Resident cardiac progenitor cells show homing properties when injected into the injured but not into the healthy myocardium. The molecular background behind this difference in behavior needs to be studied to elucidate how adult progenitor cells can restore cardiac function of the damaged myocardium. Since the brain-derived neurotrophic factor (BDNF) moderates cardioprotection in injured hearts, we focused on delineating its regulatory role in the damaged myocardium.
Publication Title
Brain derived neurotrophic factor contributes to the cardiogenic potential of adult resident progenitor cells in failing murine heart.

Description
In seed plants, leaves are born on radial shoots but unlike shoots they are determinate dorsiventral organs made of flat lamina. YABBY genes are found only in seed plants and in all cases studied, are expressed primarily in lateral organs and in a polar manner. Despite their simple expression, Arabidopsis plants lacking all YABBY gene activities have a wide range of morphological defects in all lateral organs as well as the shoot apical meristem. Here we show that leaves lacking all YABBY activities are initiated as dorsiventral appendages but fail to properly activate lamina programs. In particular, the activation of most CIN-TCPs does not commence, SAM-specific programs are reactivated, and a marginal leaf domain is not established. Altered distribution of auxin signalling and the auxin efflux carrier PIN1, highly reduced venation, initiation of multiple cotyledons, and gradual loss of the SAM accompany these defects. We suggest that YABBY functions were recruited to mould modified shoot systems into flat plant appendages by translating organ polarity into lamina specific programs that include marginal auxin flow and activation a maturation schedule directing determinate growth.

Description
INTRODUCTION. Fixation with formalin, a widely adopted procedure to preserve tissue samples, leads to extensive degradation of nucleic acids and thereby compromises procedures like microarray-based gene expression profiling. We hypothesized that RNA fragmentation is caused by activation of RNAses during the interval between formalin penetration and tissue fixation. To prevent RNAse activation, a series of tissue samples were kept under-vacuum at 4C until fixation and then fixed at 4C, for 24 hours, in formalin followed by 4 hours in ethanol 95%.

Formalin fixation at low temperature better preserves nucleic acid integrity.

Description
A-to-I RNA editing levels differ across tissues and cell types, but regulators of the editing process are largely unknown. We used RNA-seq on whole fly brains with different RNA binding proteins knocked down to test for A-to-I RNA editing level differences between controls and knockdowns. Overall design: To screen for editing regulators in the Drosophila brain, we crossed a pan-neuronal Gal4 driver, C155-Gal4, to different UAS-shRNA lines targeting individual RNA binding proteins, extracted RNA and made RNA-seq libraries. We sequenced four total replicates of shGFP controls and two replicates of all RNA binding protein knockdowns.

Description
Aminaphtone, a drug used in the treatment of chronic venous insufficiency (CVI), showed a remarkable role in the modulation of several vasoactive factors, like endothelin-1 and adhesion molecules. We analysed in vitro the effects of Aminaphtone on whole-genome gene expression. ECV304 endothelial cells were stimulated with IL-1 100 U/ml in the presence or absence of Aminaphtone 6 g/ml. Gene expression profiles were compared at 1, 3, and 6 h after stimulation by microarray.
