Project description:Total RNA was isolated from n=3 culture wells per siRNA treatment group, from 6 independent primary neonatal rat cardiomyocyte isolations. RNA was pooled to obtain n=3 independent samples per siRNA treatment group for sequencing. The siRNA treatment groups were= siScr (Scramble control), siBtg12 (Btg1/Btg2 double knockdown), siBtg1 (Btg1 single knockdown), siBtg2 (Btg2 single knockdown).

Project description:The human BTG1 and BTG2 genes are targeted by genetic alterations in hematological malignancies. In this study we examined the unique and overlapping functions of Btg1 and Btg2 in mouse B cell development. Mice deficient for Btg1 and Btg2 displayed the strongest phenotype with a decrease in B cell numbers in bone marrow due to impaired B cell commitment and immature B cell differentiation. To determine the underlying mechanism, microarray expression analyis was performed on early (B220+ CD43+) and late (B220+ CD43-) B cells of WT and Btg1;Btg2 dKO mice. Total RNA obtained from sorted B220+ CD43+ ( Hardy fractions ABC) and B220+ CD43- (Hardy fractions DEF) BM cells of WT and Btg1-/-;Btg2-/- mice. In total 4 samples were analyzed and no replicates were included.

Project description:We addressed the question of which protein kinases are expressed in cardiomyocytes. We assessed the changes during postnatal development, comparing profiles in rat neonatal ventricular cardiomyocytes (NVMs) with adult ventricular cardiomyocytes (AVMs). Neonatal and adult rat ventricular cardiomyocytes prepared according to established procedures (Marshall et al. PLoS ONE 2010 5(4):e10027; Fuller and Sugden, FEBs Lett. 1989 247:209-12; Rodrigues and Severson In Biochemical Techniques in the Heart (McNeill, J. H., Ed.) pp 101-115, CRC Press, New York.). mRNA expression profiles compared using Affymetrix rat genome 230 2.0 arrays.

Project description:Quiescence is a cellular state in which cells undergo reversible cell cycle arrest in response to environmental challenges or lack of stimuli. When favourable conditions are engaged, the cells exit quiescence and start to proliferate. For example, quiescent stem cells and oocytes are activated by differentiation signals and fertilization, respectively. The regulation of quiescent state is also crucial for lymphocytes, such as T cells. Inappropriate activation of T cells often leads to autoimmune diseases and thus, the balance between quiescent and activated T cells must be preserved. Despite its importance, however, how T cells maintain the ‘quiescent state’ and exit from it remain largely unknown. Here, we identify BTG1 and BTG2 (BTG1/2) as factors responsible for T cell quiescence. Knockout of Btg1/2 in T cells resulted in a reduced threshold to T cell activation, increased proliferation and a concomitant reduction of the frequency of naive T cells. Loss of BTG1/2 rendered naive T cells to become spontaneously activated even without TCR stimuli. Interestingly, we found a global increase in mRNA abundance in naive T cells that lack BTG1/2. In addition, depletion of BTG1/2 led to an increase in mRNA half-life and poly(A) tail length. Thus, BTG1/2 promotes deadenylation and degradation of mRNA in naive T cells. Our study demonstrates a key mechanism underlying T cell quiescence, and suggests low mRNA abundance as a key feature for maintaining quiescent T cells.

Project description:Study on changes in gene expression in primary cultures of neonatal rat ventricular cardiomyocytes to electric stimulation. Through comparing non-stimulated, stimulated and blebbistatin supplemented and stimulated cultures we set out to identify the genes that are specifically activated by electric pulsing separate from cardiomyocyte contractions. After initial recovery phase, primary cultures of neonatal rat ventricular cardiomyocytes were cultured for 3 days without pulsing, with electric pulsing or with electric pulsing combined with blebbistatin. Per treatment: 3 arrays, with samples obtained from 3 separate series of cardiomyocyte isolation and culturing. Per array: sample prepared from pooled (1:1) RNA from duplicate experiments.
