Affymetrix Rice Genome Array (rice)
Description
Plant hormones interact with each other and regulate gene expression to control plant growth and development. To understand the complex network, accumulation of comprehensive and integrative data of gene expression and hormone concentration is important. Using microarray, global gene expression profile was analyzed to compare with plant hormone concentration in 14 parts of rice at reproductive stage.

Illumina HiSeq 2500
Description
During a binary cell fate decision, a progeny silences the gene expression program associated with the alternative fate. Helper versus cytotoxic lineage decision in the thymus has been studied as a model for gene silencing of alternative lineage genes, including Cd4. While RUNX3 is required for the initiation of Cd4 silencing, it remains unknown how silenced states of Cd4 and other helper lineage genes are maintained. We show that the histone methyltransferase G9a is necessary for heritable silencing of Cd4 and other helper lineage genes in CD8 T cells. Despite normal Cd4 downregulation during the development, G9a-deficient CD8 T cells fail to maintain silencing of helper lineage genes when they repeatedly divide under non-inflammatory conditions. However, Cd4 depression is prevented during division driven by elevated TCR signaling and an inflammatory cytokine signaling. These results reveal the requirement for G9a in silencing of helper lineage genes in CD8 T cells and also suggest that CD8 T cells employ an alternative mechanism to maintain their cellular identity during immune responses. Overall design: RNA-sequencing on CD4+CD8+ G9a KO, CD4–CD8+ G9a KO, and CD4–CD8+ G9a WT T cells after 4 weeks of proliferation in a lymphopenic environment. ChIP-sequencing on H3K9me3 IP''ed from Ehmt2+/+ and Ehmt2-/- CD8+ T cells cultured in vitro with antibodies to CD3 and CD28

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Inhibiting the unfolded protein response (UPR) can be a therapeutic approach, especially for targeting the tumor microenvironment. We found that compound C (also known as dorsomorphin) prevented the UPR and exerted enhanced cytotoxicity during glucose deprivation. The UPR-inhibiting activity of compound C was not associated with either AMPK or BMP signaling inhibition.
Publication Title
Compound C prevents the unfolded protein response during glucose deprivation through a mechanism independent of AMPK and BMP signaling.

Description
Cancer cells consume large amounts of glucose because of their specific metabolic pathway. However, cancer cells exist in tumor tissue where glucose is insufficient. To survive, cancer cells likely have the mechanism to elude their glucose addiction. Here we show that functional mitochondria are essential if cancer cells are to avoid glucose addiction.
Publication Title
Mitochondria regulate the unfolded protein response leading to cancer cell survival under glucose deprivation conditions.

Description
We examined the effect of quercetin on the gene expression and function of epididymal adipose tissue (EAT) in Western diet-induced obese mice. Quercetin suppressed the increase in the number of macrophages and the decrease in the ratio of CD4+ to CD8+ T cells in EAT, and the elevation of plasma leptin and TNF levels in mice fed the Western diet. Comprehensive gene expression analysis revealed that quercetin suppressed gene expression associated with the accumulation and activation of immune cells, including macrophages and lymphocytes in EAT. It also improved the expression of the oxidative stress-sensitive transcription factor NFB, NADPH oxidases, and antioxidant enzymes. Quercetin markedly increased gene expression associated with mitochondrial oxidative phosphorylation and mitochondrial DNA Quercetin most likely universally suppresses the accumulation and activation of immune cells, including anti-inflammatory cells, whereas it specifically increased gene expression associated with mitochondrial oxidative phosphorylation. Suppression of oxidative stress and NFB activity likely contributed to the prevention of the accumulation and activation of immune cells and resulting chronic inflammation.

Description
Astaxanthin alleviates hepatic lipid accumulation and peroxidation, inflammation, and fibrosis in mice with high-cholesterol, high-cholate, and high-fat (CL) diet-induced nonalcoholic steatohepatitis (NASH). It has been proposed as a potential new treatment to inhibit the progression of NASH in humans. Therefore, we compared hepatic gene expression profiles after treatment with astaxanthin or the antioxidant vitamin E in mice with CL diet-induced NASH. Comprehensive gene expression analyses of the livers of mice fed a standard, CL, or CL diet containing astaxanthin or vitamin E for 12 weeks were performed using a DNA microarray. Both astaxanthin and vitamin E effectively improved gene expression associated with eukaryotic initiation factor-2 (EIF2) signaling, which is suppressed in NASH by endoplasmic reticulum (ER) stress in the liver.

Description
In sexual reproduction, a proper communication and cooperation between male and female organs and tissue are essential for male and female gametes to unite. In flowering plants, female sporophytic tissues and gametophyte direct a male pollen tube towards an egg apparatus, which consists of an egg cell and two synergid cells. The cell-cell communication between the pollen tube and the egg apparatus, such as the reception of a signal from the egg apparatus at the pollen tube, makes the tip of pollen tube rapture to release the sperm cell. To isolate male factors involved in the interaction between a pollen tube and an egg apparatus, we focused on receptor-like kinases (RLKs), which are extensively diversified in the flowering plant lineage to comprise a large monophyletic gene family. Approximately 620 members were found in the Arabidopsis thaliana genome. Expression patterns of 558 RLKs were analyzed using an Affymetrix ATH1 microarray of A. thaliana. We focused on two RLKs, ANXUR1 (ANX1) and ANXUR2 (ANX2), and characterized their function. Here we report that pollen tubes of anx1/anx2 ruptured before arriving at the egg apparatus, suggesting that ANX1 and ANX2 are male factors controlling pollen tube behavior with directing rupture at proper timing. Furthermore, ANX1 and ANX2 were the most closely related paralogs to a female factor FERONIA/SIRENE controlling pollen tube behavior expressed in synergid cells. Our finding shows that the coordinated behaviors of female and male reproductive apparatuses are regulated by the sister genes, whose duplication might play a role in the evolution of fertilization system in flowering plants.
Publication Title
ANXUR1 and 2, sister genes to FERONIA/SIRENE, are male factors for coordinated fertilization.
