The 42.5\u02daC is well known as inflection point of hyperthermia and generally up to 42\u02daC of hyperthermia is used in clinical case to combine with other therapy. Here, the effects of heat stress at 42 or 44\u02daC 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 44\u00b0C for 90 min) and followed by incubation for 0, 6, or 12 h at 37\u00b0C. The percentage of cell death was 5.0 \u00b1 1.5 (mean \u00b1 SD) at 42\u00b0C for 12 h and 17.4 \u00b1 0.6 at 44\u00b0C 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 44\u00b0C. HSC-3 human oral squamous carcinoma cells were treated with heat stress (42 or 44\u00b0C for 90 min) and followed by incubation for 0, 6, or 12 h at 37\u00b0C. Non-treated cells were served as control. Total RNA samples were prepared from the cells. Gene expression was analyzed by an Affymetrix GeneChip\u00ae system with a Human Genome U133-plus 2.0 array for analysis of over 47,000 transcripts. Sample preparation for array hybridization was carried out as described in the manufacturer\u2019s instructions.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-24783", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-24783/samples/"}
