Project description:In order to identify common gene expression across other gliopathic bang senstiive genes (i.e. genes that when knocked down or over expressed by repo-GAL4 cause seizures) we crossed six UAS-RNAi or UAS-over-expression lines for known bang senstive genes to repo-GAL4. We pooled total RNA from brains of these animals in equal amounts and ran microarray analysis to search for transcripts that are common among these six seizure associated genes.
Project description:Sensitive skin is a hyperactive skin condtion, characterized by prickling, burning, itching, stinging, pain, or tingling sensation, which develops in response to various internal and external stimulants that can be tolerated by most people. The pathophysiology involved in the development of sensitive skin remains largely elusive. To characterize differential gene expression profiles in sensitive skin, we investigated the genome-wide patterns of gene expression from skin samples from subjects with sensitive or non-sensitive skin, following lactic acid challenge or normal saline application using cDNA microarrays.
Project description:Two cell lines were utilized to determine hormone sensitive chromatin marks. Specficially this study identifies the H3K4me pattern in response to hormone treatment. This chromatin mark is believed do demarkate genes which are 'poised' to be transcriptionally activated. We have found differential H3K4me sites both common and unique in each cell type. Many of these correlate with previous studies of ecdysone sensitive genes.
Project description:To explore gene expression profiles of cells sensitive to necrosis (such as L929 cells) and those sensitive to apoptosis (such as NIH3T3 cells), we conducted expression microarray analysis of L929 cells and NIH3T3 cells.
Project description:Sensitive skin is a hyperactive skin condtion, characterized by prickling, burning, itching, stinging, pain, or tingling sensation, which develops in response to various internal and external stimulants that can be tolerated by most people. The pathophysiology involved in the development of sensitive skin remains largely elusive. To characterize differential gene expression profiles in sensitive skin, we investigated the genome-wide patterns of gene expression from skin samples from subjects with sensitive or non-sensitive skin, following lactic acid challenge or normal saline application using cDNA microarrays. We recruited eighteen healthy volunteers with sensitive skin (n=9) or non-sensitive skin (n=9). From each subject, two skin samples were obtained following lactic acid or normal saline application.(18 samples/group) Based on the existence of sensitive skin and lactic acid challenge, samples were pooled into sets of three individuals each. Global transcriptome profiling was conducted using Affymetrix Human Genome U133 Plus 2.0 array.
