Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Using PAXgene tubes, peripheral blood samples were collected from seven patients >18 years with documented pdm(H1N1) influenza, bilateral chest infiltrates, and in need of ventilation support. Significant co-morbidity was exclusion criterion. Expression profiles were compared with 7 age matched controls. Using a false discovery rate < 5% and an absolute fold change > 2, 370 genes were differentially expressed in case and controls.

Description
Hyperthermia is widely used to treat patients with various cancers. The 42.5C is well known as inflection point of hyperthermia and generally up to 42C of hyperthermia is used in clinical case to combine with other therapy. Here, the effects of heat stress at 42 or 44C for 90 min on the gene expression in HSC-3 human oral squamous carcinoma cells were investigated using an Affymetrix GeneChip system. The cells were treated with heat stress (42 or 44C for 90 min) and followed by incubation for 0, 6, or 12 h at 37C. The percentage of cell death was 5.0 1.5 (mean SD) at 42C for 12 h and 17.4 0.6 at 44C for 12 h. Of approximately 47,000 probe sets analyzed, many genes that were differentially expressed by a factor 2.0 or greater were identified in the cells treated with heat stress at 42 and 44C.

Description
Hyperthermia is widely used to treat patients with various cancers. 42.5C is well known as the inflection point of hyperthermia and generally up to 42C of hyperthermia is used in clinical cases combined with other therapies. Here, the effects of heat stress at 42 or 44C for 15 min on the gene expression in human lymphoma U937 cells were investigated using an Affymetrix GeneChip system. The cells were treated with heat stress (42 or 44C for 15 min), followed by incubation for 0, 1, 3 or 6 h at 37C. The percentage of DNA fragmentation was 8.4 2.2 (mean SD) at 42C for 6 h and 21.0 2.0 at 44C for 6 h. Of approximately 47,000 probe sets analyzed, many genes that were differentially expressed by a factor 2.0 or greater were identified in the cells treated with heat stress at 42 and 44C.

Description
Hyperthermia (41C <) is widely used to treat patients with various cancers. Here, the effects of hyperthermia (42C for 90 min) on the gene expression in human lymphoma U937 cells were investigated using an Affymetrix GeneChip system. The cells were treated with hyperthermia (42C for 90 min) and followed by incubation for 0, 1, 3 or 6 h at 37C. The percentage of DNA fragmentation was 7.5 0.9 (mean SD), 10.1 0.2, and 17.3 2.3 at the incubation periods of 1, 3, and 6 h, respectively. Of approximately 47,000 probe sets analyzed, the hyperthermia down-regulated 4,214 probe sets and up-regulated 1,334 by a factor 2.0 or greater.

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.

Description
In most metazoan nuclei, heterochromatin is located at the nuclear periphery in contact with the nuclear lamina, which provides mechanical stability to the nucleus. We show that in cultured cells, chromatin de-compaction by the nucleosome binding protein HMGN5 decreases the sturdiness, elasticity, and rigidity of the nucleus. Mice overexpressing HMGN5, either globally or only in the heart, are normal at birth but develop hypertrophic heart with large cardiomyoctyes, deformed nuclei and disrupted lamina, and die of cardiac malfunction. Chromatin de-compaction is seen in cardiomyocytes of newborn mice but misshaped nuclei with disrupted lamina are seen only in adult cardiomyocytes, suggesting that loss of heterochromatin diminishes the ability of the nucleus to withstand the mechanical forces of the contracting heart. Thus, heterochromatin enhances the ability of the nuclear lamina to maintain the sturdiness and shape of the eukaryotic nucleus; a structural role for chromatin that is distinct from its genetic functions.

Description
Echo-contrast agents enhance the echogenicity of ultrasound and have been clinically used for diagonosis in current medical fields. Here, the combined effects of Sonazoid, an echo-contrast agent, and ultrasound on the gene expression in human lymphoma U937 cells were investigated using an Affymetrix GeneChip system. The cells were treated with Sonazoid (0.05%; Sonazoid only), ultrasound (0.3 W/cm2 for 1 min; ultrasound only) and the combination of Sonazoid and ultrasound (0.05% Sonazoid plus ultrasound 0.3 W/cm2 for 1 min; Sonazoid + Ultrasound) and followed by incubation for 3 h at 37C. The percentage of DNA fragmentation 6 h after treatment was 5.8 1.0 (mean SD, n = 3), 6.0 0.4, 13.5 1.0, and 18.3 2.3 in cells treated with control, Sonazoid only, ultrasound only and Sonazoid + Ultrasound, respectively. Of approximately 47,000 probe sets analyzed, probe sets that were differentially expressed by a factor 2.0 or greater were 40, 184 and 144 in cells treated with Sonazoid only, ultrasound only and Sonazoid + Ultrasound, respectively.
