Project description:We have reported previously that when chromosome Y (chrY) from the mouse strain C57BL/6J (abbreviated as B) was substituted for that of A/J mice (ChrY<A>), cardiomyocytes from the resulting 'chromosome substitution' C57BL/6J-chrY<A> strain (abbreviated as B.Y) were smaller than that of their C57BL/6J counterparts. In reverse, when chrY<A> from A/J mice was substituted for that of chrY<B>, cardiomyocytes from the resulting A/J-chrY<C57> strain were larger than in their A/J counterparts. We further used these strains (B and the consomic B.Y) to test whether the origin of chrY could also be linked to differences in the profile of gene expression in their cardiac left ventricles in adult mice where either sham surgery (intact animals) or castration has been performed at 3-4 weeks of age..

Samples from 4 different mice were used in each group. For hybridization, probes generated from samples were randomized on 2 different Illumina MouseRef v2.0 BeadChips.
Project description:Wild-type (WT) C57Bl/6 and akt2-/- male mice. Keywords: RNA Expression Array Left ventricles (LV) from 12-16 week-old male wild type mice and age-matched akt2-/- mice
Project description:The medial and cardiac lobes of the right lung and whole right lung of (initially) 10-12 week old C57BL/6 mice were transcriptome profiled at days 0, 3, 7, 14, 28 and 56 post left pneumonectomy, with day 0 being pre-pneumonectomy, and an additional day 56 post sham surgery to control for 8 week aging post left pneumonectomy.
Project description:We monitored gene expression in the liver of 10-12 week-old male C57BL/6J mice for 24 hours before and until 48 hours after the end of a single total sleep deprivation (SD) episode. The aim was to characterise the response to SD and recovery thereafter.
Project description:Analysis of angiotensin II effect on left ventricle at gene expression level. The hypothesis tested in the present study was that angiotensin II treatment may affect gene expression in left ventricle in a strain specific manner. Results provide important information about which genes respond to angiotensin II in C57Bl/6N male mice compared to their C57Bl/6J counterparts. Total RNA obtained from isolated left ventricles from C57Bl/6J and C57Bl/6N mice subjected to 48 hours of angiotensin II infusion, via osmotic mini-pumps (500ng/kg/h) implanted sub-cutaneously, compared to sham operated controls.
Project description:We analysed the combined effects of exposure to maternal diabetes and disrupted HIF-1 signaling on the transcriptom in cardiac left ventricles of 12 weeks old male mice. This approach provides the information about the long term changes originating in utero due to maternal diabetes and inefficient response to hypoxia which develops as a result of hyperglycemia. The majority of changes were detected in Hif1a insufficient mice exposed to maternal diabetes.
Project description:We monitored gene expression and chromatin accessibility in the cerebral cortex of 10-12 week-old male C57BL/6J mice for 24 hours before and until 48 hours after the end of a single total sleep deprivation (SD) episode. The aim was to characterise the response to SD and recovery thereafter.
