Analysis of myelomonocytic lymphoma U937 cells subjected to mild hyperthermia. Mild hyperthermia alone does not induce apoptosis but it does show a synergism with radiotherapy and anti-cancer drugs. Results provide insight into molecular mechanisms underlying cellular responses to mild hyperthermia.

(Submitter supplied) The rationale underlying hyperthermia is the fact that temperatures over 42.5˚C are highly cytotoxic to tumor cells. On the other hand, although mild hyperthermia at a range from 39 to 41˚C alone did not induce cytotoxicity in tumor cells, mild hyperthermia is reported to show a synergism with radiotherapy and anti-cancer drugs. Here, the effects of mild hyperthermia (41˚C for 30 min) on the gene expression in human lymphoma U937 cells were investigated using by an Affymetrix GeneChip system. more...

(Submitter supplied) Hyperthermia (41˚C <) is widely used to treat patients with various cancers. Here, the effects of hyperthermia (42˚C 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 (42°C for 90 min) and followed by incubation for 0, 1, 3 or 6 h at 37°C. 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. more...

(Submitter supplied) Here, the effects of non-thermal low intensity pulsed ultrasound (LIPUS) on the gene expression in human lymphoma U937 cells were investigated using by an Affymetrix GeneChip system. Six hours after LIPUS treatment (0.3 W/cm2 for 1 min), apoptosis (14±3.8%, mean±SD) with minimal cell lysis was observed. At 3 h post-treatment, LIPUS down-regulated 193 genes and up-regulated 201 genes by >1.5-fold. Keywords: ultrasound, gene expression, Human lymphoma U937 cell

(Submitter supplied) Hyperthermia is widely used to treat patients with various cancers. 42.5˚C is well known as the inflection point of hyperthermia and generally up to 42˚C of hyperthermia is used in clinical cases combined with other therapies. Here, the effects of heat stress at 42 or 44˚C 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 44°C for 15 min), followed by incubation for 0, 1, 3 or 6 h at 37°C. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Anisomycin is known as a potent apoptosis inducer by activating JNK/SAPK and inhibiting protein synthesis during translation. However, only few details are known on the mechanism of apoptosis induced by this compound. Genes in apoptosis induced by anisomycin in human leukemia U937 cells were investigated by using an Affymetrix GeneChip system. DNA fragmentation and phosphatidylserine externalization assays clearly demonstrated that anisomycin induced apoptosis in a time- and concentration- dependent manner. more...

(Submitter supplied) The alkylating agent N-methyl-N’-nitro-N-nitrosoguanidine (MNNG) induces cellular DNA damages and other comprehensive alterations that lead to chromosomal aberrations, mutations, tumor initiations, and cell death. However, the molecular mechanism of MNNG-induced cellular stress remains unclear.We have genome-wide analyzed early transcriptional responses of human FL amnion epithelial cells after exposure to three relatively low doses of MNNG (0.2, 1.0, and 10.0µM),and differential gene expression profiles were obtained 4 h after exposure using oligonucleotide microarrays followed by validation with quantitative real-time RT-PCR. more...

(Submitter supplied) 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. The effects of heat stress at 41°C for 30 min (mild hyperthermia) on the gene expression in human oral squamous cell carcinoma HSC-3 cells were investigated using an Affymetrix GeneChip system.
