Description
The mitochondrial superoxide dismutase (SOD2) is a major antioxidant protein which detoxifies superoxide anion radicals generated by mitochondrial respiration (Weisiger and Fridovich, J. Biol. Chem. 1973). We designed a model of oxidative stress-induced anemia caused by SOD2-deficiency (Friedman et al. J. Exp. Med. 2001). Our previous work showed that mice reconstituted with SOD2-deficient hematopoietic stem cells develop an anemia with striking similarity to human sideroblastic anemia (SA) (Friedman et al. Blood 2004; Martin et al. Exp Hematol 2005). Our overall goal was to define early events in the pathogenesis of SOD2-deficiency SA and, in particular, to identify genes involved in the response of erythroid progenitors to oxidative stress. We compared gene expression of sorted TER-119+ CD71+ erythroblasts from SOD2-/- ('KO') versus Sod2+/+ ('WT') hematopoietic stem cell recipients using cDNA microarrays.

Description
We describe a novel subset of CD8+ DCs in lymphoid organs of nave mice characterized by expression of the CX3CR1 chemokine receptor. CX3CR1+CD8+ DCs lack hallmarks of classical CD8+ DCs, including IL12 secretion, the capacity to cross-present antigen and their developmental independence of the transcriptional factor BatF3. Gene expression profiling showed that CX3CR1+CD8+ DCs resemble CD8- cDCs. The microarray analysis further revealed a unique plasmacytoid DC (PDC) gene signature of CX3CR1+ CD8+ DCs. A PDC relationship of the cells is further supported by the fact that they harbor characteristic D-J immunoglobulin gene rearrangements and that development of CX3CR1+CD8+ DCs requires E2-2, the critical transcriptional regulator of PDCs. Thus, CX3CR1+ CD8+ DCs represent a unique DC subset, related to but distinct from PDCs.

Description
Restricted feeding impacts the hepatic circadian clock of WT mice. Cry1, Cry2 double KO mice lack a circadian clock and are thus expected to show rhythmical gene expression in the liver. Imposing a temporally restricted feeding schedule on these mice shows how the hepatic circadian clock and rhythmic food intake regulate rhythmic transcription in parallel

Description
Cardiac hypertrophy can lead to heart failure, and is induced either by physiological stimuli eg postnatal development, chronic exercise training or pathological stimuli eg pressure or volume overload. Majority of new therapies for heart failure has mixed outcomes. A combined mouse model and oligo-array approach are used to examine whether phosphoinositide 3-kinase (p110-alpha isoform) activity is critical for maintenance of cardiac function and long-term survival in a setting of heart failure. The significance and expected outcome are to recognise genes involved in models of heart failure ie pathological- vs physiology-hypertrophy, and examine the molecular mechanisms responsible for such activity.

Description
Temporally restricted feeding has a profound effect on the hepatic circadian clock. While the circadian clock is largely unaffected by by extensive fasting, many transcripts are known to be affected by a fasting paradigm. This dataset shows the effect of extensive fasting on dynamic gene expression in the liver
