Project description:Transcriptional profiling of fully developed leaves of Arabidopsis Col0 plants heat-stressed for 25 min at 27.7 degrees Celsius. Goal was to isolate and study the influence of temperature and vpd change in the 30 min high light-stress experiments, since the Isolight rises leaf temperature to 27.5C and increases the vpd from 5 min of exposure.

Project description:This study measured the differential expression of genes from a single clonal Daphnia pulex isolate obtained from an eutrophic flooded opencast mine near Gräfenhain (Saxony, Germany) and has been kept in the laboratory since 2002. The daphniids (50 adult animals per batch) were raised in 3-L glass beakers under a 16 h:8 h L:D photoperiod. Three-quarter of the culture medium (M4) was renewed once a week, and the animals were equally fed ad libitum with algae (Desmodesmus subspicatus; SAG 53.80, Göttingen, Germany). Long-term-acclimated animals were kept at three different temperatures (i.e., 10 ± 0.5°C, 20 ± 0.3°C, and 24 ± 0.3°C) under normoxia (Po2 ≥ 20 kPa) for at least twelve weeks. Time-resolved experiments (acute heat stress) were carried out with long-term 20°C acclimated animals, which were exposed for three different time intervals (2, 4, and 8 h) to either 30 ± 0.2°C (test conditions) or 20 ± 0.3°C (control conditions). For this, 50 animals each were rapidly transferred with a sieve (mesh size: 1.2 mm) from 20°C-medium to a set of beakers containing 30°C-medium. As control, 50 animals each were transferred from 20°C-medium to another set of beakers with 20°C-medium. Only adult female animals with a body length of 2−2.5 mm (between the base of the apical spine and the anterior part of the head) and carrying parthenogenetic eggs and embryos were used for experiments. Animals were not fed during short-term exposures. During experiments, all animals were in good physical condition. After thermal acclimation or heat exposure, animals were transferred into 1.5-ml microcentrifuge tubes and shock-frozen in liquid nitrogen after removing adhering water with a tissue paper. Samples were short-term stored at -80°C. For all experimental conditions, four independent replicates (50 animals each) were analyzed. This GEO record is for the contrasts between animals conditioned to 10 degrees Celsius (condition 1) versus 20 degrees Celsius (condition 2), 10 degrees Celsius (condition 1) versus 24 degrees Celsius (condition 3), and 20 degrees Celsius (condition 2) versus 24 degrees Celsius (condition 3)

Project description:JN54 (wild-type) cells were incubated in YPD medium at 30 degrees C to a logarithmic phase (OD660=1), followed by treatment with mild heat-shock at 43 degrees C for 30 min in pre-warmed (43 degrees C) 100ml of YPD medium using 500 ml Erlenmeyer flask. JN54 (wild-type) cells were incubated in YPD medium at 30 degrees C to a logarithmic phase (OD660=1), followed by treatment with mild heat-shock at 43 degrees C for 60 min in pre-warmed (43 degrees C) 100ml of YPD medium using 500 ml Erlenmeyer flask.

Project description:Male ferrets, aged 3 months, were divided into two group: one group remained at 22 degrees Celsius, while the other group was acclimatized to 4 degrees Celsius for one week. After sacrification, inguinal and periaortic white adipose tissues were dissected, and used for RNA isolation and subsequent global gene expression profiling using custom Agilent ferret-specific 2x400K microarrays. Data analysis indicated that while the cold exposure induces an increase on metabolism in inguinal white adopose tissue, in periaortic white adipose tissue this stimulus induces a reduction on expression of genes involved in cell cycle and in immune response.

Project description:Male ferrets, aged 3 months, were divided into two group: one group remained at 22 degrees Celsius, while the other group was acclimatized to 4 degrees Celsius for one week. After sacrification, inguinal and periaortic white adipose tissues were dissected, and peripheral blood mononuclear cells (PBMC) were isolated. The three tissues are used for RNA isolation and subsequent global gene expression profiling using custom Agilent ferret-specific 2x400K microarrays. Data analysis indicated that the cold exposure induce a clear gene expression response of some genes in the inguinal and periaortic white adipose tissue as in PBMC. These genes could be defined as a biomakers of the effect of cold exposure in these cells.

Project description:Mms21 deleteion in Candida albicans resulted in invasveness and filamentatation in YPD media at 30 degrees Celsius. Wild type SN148 do not make any Filaments in YPD at 30 degrees Celsius. The aim was to look for transcription profiling mms21 dleleted mutant against wild type to find genes up and down regulated in the mutant especially thoseones critical for filamentation.

Project description:After measuring the transcriptional response to increasing exposure of Caenorhabditis elegans N2 to 35 degrees Celsius, we wondered how recovery from heat-stress would progress. Hence, we exposed populations of the N2 strain to a 2 hour heat-shock of 35 degrees Celsius and took samples from 0 - 7 hours after termination of stress. This experiment was conduced in three biological replicates.

Project description:From preliminary experiments, HSP70 deficient MEF cells display moderate thermotolerance to a severe heatshock of 45.5 degrees after a mild preshock at 43 degrees, even in the absence of hsp70 protein. We would like to determine which genes in these cells are being activated to account for this thermotolerance. Experiment Overall Design: Two cell lines are analyzed - hsp70 knockout and hsp70 rescue cells. 6 microarrays from the (-/-)knockout cells are analyzed (3 Pretreated vs 3 unheated controls). For the (+/+) rescue cells, 4 microarrays are used (2 pretreated and 2 unheated controls). Cells were plated at 3k/well in a 96 well plate, covered with a gas permeable sealer and heat shocked at 43degrees for 30 minutes at the 20 hr time point. The RNA was harvested at 3hrs after heat treatment.
