Vibrio cholerae Freezing Study

ABSTRACT: Question Addressed: Does gene expression in V. cholerae change when samples are frozen at -80 degrees? An in vitro grown culture of O1 Inaba ICDDR,B (strain DSM-V999 described in Nature. 2002 Jun 6;417(6889):642-5) that had been grown to exponential phase (OD600 + 0.2) was placed in a 15 ml conical and then placed in a -80 degree freezer. A portion of the starting culture was harvested prior to freezing to serve as the control/reference for downstream hybridizations. RNA was recovered from the non-frozen sample as well as by prepping material directly from frozen samples. Labeling reactions were performed in quadruplicate for each sample. A replicate experimental design type is where a series of replicates are performed to evaluate reproducibility or as a pilot study to determine the appropriate number of replicates for a subsequent experiments.

Transcription profiling of human oral lesions treated with bioadhesive black rasberry gel to determine the effect on gene expression and proinflammatory proteins

Project description:This portion of the study evaluated the effects of topical 10% black raspberry gel application on gene expression profiles of premalignant oral lesions. Topical application of the bioadhesive black rasberry gel was observed to modulate gene expression and reduce proinflammatory proteins in human premalignant oral lesions. Experiment Overall Design: Each patient served as their own internal control. A pretreatment specimen of the premalignant lesion was obtained for baseline parameters. Following six weeks of treatment, the treated lesional tissue was removed. All tissue samples were immediately placed in RNA later and placed in a -80 degree freezer until sample preparation.

wild type two hours exposure to zymolyase

Project description:S. cerevisiae was grown on YEPD. For Zymolyase experiments, yeast cells were grown overnight at 24 °C to an optical density 0.8 - 1 (A600). The culture was refreshed to 0.2 O.D and grown at 24 °C for 2h 30min. Next, culture was divided into two parts. One continues growing under same conditions (non-treated culture) while the other was supplemented with 5units/ml Zymolyase 100T . Cells were collected at 2 hours of growth, frozen at -80 °C and processed for RNA extraction. Keywords: repeat sample

Wild type 4 hours exposure to congo red (cell wall chip)

Project description:S. cerevisiae was grown on YEPD. For Congo Red experiments, yest cells were grown overnight at 24 °C to an optical density 0.8 - 1 (A600). The culture was refreshed to 0.2 O.D and grown at 24 °C for 2h. Next, culture was divided into two parts. One continues growing under same conditions (non-treated culture) while the other was supplemented with Congo Red to a final concentration of 30 µg/ml. Cells were collected at 4hours of growth, frozen at -80 °C and processed for RNA extraction. Keywords: repeat sample
