- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Temporal changes of gene expression from 1-wk- to 4-wk and 8-wk-old mouse in heart, kidney and lung. Mammalian somatic growth is rapid in early postnatal life but then slows and eventually ceases in multiple tissues. We hypothesized that there exists a postnatal gene expression program that is common to multiple tissues and is responsible for this coordinate growth deceleration. Consistent with this hypothesis, microarray analysis identified >1600 genes that were regulated with age coordinately in kidney, lung, and heart of juvenile mice, including many genes that regulate proliferation. As examples, we focused on three growth-promoting genes, Igf2, Mest, and Peg3, that were markedly downregulated with age. We conclude that there exists an extensive genetic program occurring during postnatal life. Many of the involved genes are regulated coordinately in multiple organs, including many genes that regulate cell proliferation. At least some of these are themselves apparently regulated by growth, suggesting that, in the embryo, a gene expression pattern is established that allows for rapid somatic growth of multiple tissues but then, during postnatal life, this growth leads to negative-feedback changes in gene expression that in turn slow and eventually halt somatic growth, thus imposing a fundamental limit on adult body size.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Turner Syndrome (TS) is the most common X chromosome aneuploidy disorder in female, and the predominant karyotype is 45X, a complete loss of the second sex chromosome. Depending on the parental origin of the single X chromosome, 45X patients can be further divided into two groups: 45Xm and 45Xp with maternal and paternal inherited X chromosome, respectively. TS patients of 45Xm and 45Xp are found to associate with different severity in phenotype, including prevalence for cardiovascular disease.

- Affymetrix Rat Genome 230 2.0 Array (rat2302), Affymetrix Rat Genome U34 Array (rgu34a)
Description
Biological processes are optimized by circadian and circannual biological timing systems. In vertebrates, the pineal gland plays an essential role in these systems by converting time into a hormonal signal, melatonin; in all vertebrates, circulating melatonin is elevated at night, independent of lifestyle. At night, sympathetic input to the pineal gland, originating from the circadian clock in the suprachiasmatic nucleus, releases norepinephrine. This adrenergic stimulation causes an elevation of cAMP, which is thought to regulate many of the dramatic changes in genes expression known to occur at night. In many aspects, the adrenergic/cAMP effects on gene expression can be recapitulated in primary organ culture.

Description
We aimed to identify genes that are inhibited by Kctd15 overexpression during neural crest (NC) induction. Injection of RNAs encoding Wnt3a and chordin into the embryo followed by animal cap explant culture leads to the induction of NC marker genes as well as additional genes expressed in the neural plate border. Our previous study indicated that co-injection of kctd15 inhibits the induction of these markers. We injected four sets of RNAs, lacZ as control (L), wnt3a+chd (WC), wnt3a+chd+kctd15 (WCK), and kctd15 (K). After evaluation of marker gene expression with RT-PCR, we prepared probes with same RNA extract for Affymetrix DNA microarray. The hybridization, washing and scanning were perfomed following the manual from Affymetrix. Partek Genomics Suite was employed for data analysis.

Description
Oligodendrocyte precursor cells from postnatal day 10 optic nerve remained in a developmentally immature state in LIF-/- mice. Partial recovery of myelin genes is seen in LIF-/- mice by postnatal day 14 in the optic nerve. Very little difference in myelin genes in the optic nerve is seen by postnatal day 35 (adult).
