Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Hyperthermia (HT) is widely used to treat patients with various cancers. In general, HT elicits a wide spectrum of stress responses, such as induction of heat shock proteins, protein aggregation and cell death in mammalian cells. Although many biological processes are affected by HT, the overall responses to HT in mammalian cells remain unknown.
Publication Title
Identification of common gene networks responsive to mild hyperthermia in human cancer cells.

Description
Hyperthermia is widely used to treat patients with various cancers. Here, the effects of heat stress at 41C for 30 min (mild hyperthermia) on the gene expression in OUMS-36 human normal fibroblast cells were investigated using an Affymetrix GeneChip system. The cells were treated with mild hyperthermia, followed by incubation for 0, 1, or 3 h at 37C. No cell death was observed in the mild hyperthermia-treated cells. On the other hand, many genes that were differentially expressed by a factor 1.5 or greater were identified in the cells treated with the mild hyperthermia.

Hyperthermia is widely used to treat patients with various cancers. Here, the effects of heat stress at 41C for 30 min (mild hyperthermia) on the gene expression in Hs68 human skin normal fibroblast cells were investigated using an Affymetrix GeneChip system. The cells were treated with mild hyperthermia, followed by incubation for 0, 1, or 3 h at 37C. No cell death was observed in the mild hyperthermia-treated cells. On the other hand, many genes that were differentially expressed by a factor 1.5 or greater were identified in the cells treated with the mild hyperthermia.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The objective of the present study is to investigate the role of DNA-PK inhibition in cell death induced by heat stress (44C, 60 min). Comparative gene expression analysis was performed with mock cells, negative control siRNA-treated cells and DNA-PK siRNA-treated cells. The expression of DNA-PK was confirmed by Western blotting. Gene expression was analyzed using GeneChip oligonucleotide microarrays and computational gene expression analysis tools.

Description
Parathyroid hormone (PTH) plays an essential role in regulating calcium and bone homeostasis in the adult, but whether PTH is required at all for regulating fetal-placental mineral homeostasis is uncertain. To address this we treated Pth-null mice in utero with 1 nmol PTH (1-84) or saline and examined placental calcium transfer 90 minutes later. It was found that placental calcium transfer increased in Pth-null fetuses treated with PTH as compared to Pth-null fetuses treated with saline. Subsequently, to determine the effect of PTH treatment on placental gene expression, in a separate experiment, 90 minutes after the fetal injections the placentas were removed for subsequent RNA extraction and microarray analysis.

Description
The use of in vitro cell culture systems has been of central importance for research of physiology, pharmacology, and toxicology, and functions at the cellular and molecular levels. We have developed an immortalized oral epithelial cell line ROE2 from fetal transgenic rats harboring temperature-sensitive simian virus 40 large T-antigen. Here, to identify genes involved in ROE2 cell differentiation, global-scale gene expression analysis was carried out using a GeneChip system.

Description
CD74, a Type II membrane glycoprotein and MHC class II chaperone (Ii), is normally expressed by cells associated with the immune system. CD74 also forms heterodimers with CD44 to generate receptors to macrophage migration inhibitory factor (MIF), a proinflammatory cytokine. Following targeted Cre-mediated deletion of Ikk in IkkDeltaHep mice (a strain highly susceptible to chemically-induced hepatotoxicity and hepatocarcinogenesis), CD74 is abundantly expressed by hepatocytes throughout liver acini (as detected by specific Western blots and immunohistochemical stains); it is not observed in either control IkkF/F hepatocytes or embryonic fibroblasts from Ikk-/- mice. Constitutive CD74 expression in IkkDeltaHep hepatocytes is also accompanied by significantly augmented expression of CD44 and genes associated with antigen processing and host defense. These observations suggest that IkkDeltaHep hepatocytes might directly respond to MIF signaling, accounting partly for the enhanced susceptibility of IkkDeltaHep mice to hepatotoxins and hepatocarcinogens, and also might exhibit unusual immunological properties including antigen presentation.

Description
In addition to its essential metabolic functions biotin is suggested a critical role in regulating gene expression. The first committed enzyme in biotin biosynthesis in Arabidopsis, 7-keto-8-aminopelargonic acid synthase is encoded by At5g04620 (BIO4). We isolated a novel T-DNA insertion mutant of BIO4 (bio4-1) showing a spontaneous cell death phenotype that could be rescued both by exogenous biotin and genetic complementation. The bio4-1 plants exhibited massive accumulation of hydrogen peroxide.

Biotin deficiency causes spontaneous cell death and activation of defense signaling.
