Description
During cortical development neurons are generated sequentially from basal progenitors (BPs) which specifically express the transcription factor Tbr2. We used fluorescent-activaed cell sorting (FACS) to isolate BPs from Tbr2GFP knockin reporter mice (Arnold SJ et al. Genesis, 2009) at early (embryonic day, E13) and late (embryonic day, E16) stages of cortical neurogenesis and determined mRNA expression profiles using mouse mRNA microarray (Illumina MouseWG-6 v2). Comparison of E13 and E16 mRNA expression profiles allowed us to identify regulatory gene networks for maintaining stage specific homeostasis of BPs throughout neurogenesis.

Description
OBJECTIVE: To understand the molecular pathways underlying the cardiac preconditioning effect of short-term caloric restriction (CR). BACKGROUND: Lifelong CR has been suggested to reduce the incidence of cardiovascular disease through a variety of mechanisms. However, prolonged adherence to a CR life-style is difficult. Here we show how short-term CR protects the mouse heart from ischemia. METHODS: Male 10-12 wk old C57bl/6 mice were randomly assigned to an ad libitum (AL) diet with free access to regular chow, or CR, receiving 30% less food over a period of 7 days (d), prior to myocardial infarction (MI) via permanent coronary ligation. Prior to MI (d8), the left ventricles (LV) of AL and CR mice were collected for Western blot, DNA and microRNA (miR) analyses. In separate groups, infarct size, cardiac hemodynamics and protein abundance of caspase 3 was measured at d2 post-MI. RESULTS: This short-term model of CR was associated with cardio-protection, as evidenced by decreased infarct size (18.52.4% vs. 26.61.7%, N=10/group; P=0.01). cDNA and miR profiles pre-MI (N=5/group) identified genes modulated by short-term CR to be associated with circadian clock, oxidative stress, immune function, apoptosis, metabolism, angiogenesis, cytoskeleton and extracellular matrix (ECM). Western blots pre-MI revealed CR-associated increases in phosphorylated Akt and GSK3, reduced levels of phosphorylated AMPK and mitochondrial related proteins PGC-1, cytochrome C and cyclooxygenase (COX) IV, with no differences in the levels of phosphorylated eNOS or MAPK (ERK1/2; p38). CONCLUSIONS: Short-term CR for only 7d represents a preconditioning strategy that limits infarct size. It is associated with a unique gene and miR signature, including the activation of specific pro-survival kinases. These findings may have implications for therapeutic use of short-term CR. .

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Despite numerous observations of effects of estrogens on spermatogenesis, identification of estrogen-regulated genes in the testis is limited. We previously showed in rats, in which irradiation had completely blocked spermatogonial differentiation, that testosterone (T) suppression with GnRH-antagonist and antiandrogen stimulated spermatogenic recovery and addition of estradiol (E2) to this regimen accelerated this recovery. We report here the global changes in testicular cell gene expression induced by the E2 treatment. By minimizing the changes in other hormones and also having concurrent data on the regulation of the genes by those hormones, we were able to dissect the effects of estrogen on gene expression, independent of gonadotropin or T changes. Expression of 20 genes, largely in somatic cells, was up- or down-regulated between 2- and 5-fold by E2. There were also early germ cell genes whose expression increased but this was a result of a small increase in spermatogonial numbers. The striking enrichment of transcripts not corresponding to known genes among the E2-downregulated probes led to the identification of one as micro-RNA miR-34a. We propose that genes whose expression levels are altered in one direction by irradiation and in the opposite direction by both T suppression and E2 treatment are candidates for controlling the block in differentiation. Several genes, including insulin-like 3 (Insl3), satisfied those criteria. If they are indeed involved in the inhibition of spermatogonial differentiation, they may be candidate targets for clinical treatments to enhance recovery of spermatogenesis following gonadotoxic exposures, such as those resulting from cancer therapy.

Description
ETS2 is a canonical transcriptional factor and member of the ETS family of genes. ETS2 binds to consensus ERE binding sites in a broad spectrum of genes thus affecting many intracellular molecular functions. However, the role of ETS2 in the biology and pathogenesis of lung cancers is still not known.
