Project description:Tumor resistance to anti-cancer drugs is a major huddle in chemotherapy. To identify cancer genes that contribute to chemoresistance, B16 mouse melanoma cells were used as a model. We used microarrays to decipher the specific gene regulation in doxorubicine treated B16 mouse melanoma cells. Keywords: Time course Overall design: B16 cells were treated with 1 microgram/ml of doxorubicine and the RNAs were purified at 0, 2, and 4h after the treatment.

Project description:Purpose: Chronic infection with hepatitis B virus is the leading global risk factor for the development of liver cancer. A large body of research has shown the many effects an HBV infection has on cellular physiology, particularly on pathways that may be involved in the development of HBV-associated diseases. Unfortunately, a significant portion of this research has been done in systems that may not mimic what is seen in a primary hepatocyte, and is not done on a transcriptome-wide scale. Because of this, we performed an RNA-seq analysis of primary rat hepatocytes either expressing HBV or not over a series of time points to determine the global changes HBV has on primary hepatocyte physiology. Methods: To do this RNA-seq analysis, triplicate samples of total RNA were collected from cultured primary rat hepatocytes (PRH) over the course of 72hr. PRH were collected immediately after isolation (0hr), or 24hr, 48hr, or 72hr after plating. In addition, PRH were infected 24hr after plating with adenovirus expressing GFP alone (AdGFP) or GFP along with a greater than unit length copy of the HBV genome (AdHBV) and collected at 48hr after plating (24hr after infection) or 72hr after plating (48hr after infection). cDNA libraries were sequenced using the Illumina NextSeq 500 platform to generate either 1x75bp reads. Reads were mapped using the STAR aligner, and output BAMs were further analyzed in R using the GenomicAlignments package, to quantify number of reads per transcript, and DESeq2, to determine differential expression. Reads per kilobase transcript per million total reads (RPKM) was calculated by dividing reads per transcript by the transcript length and then normalizing to the total number of reads in the sample. Results: Following this pipeline, we were able to identify a number of HBV-mediated differentially expressed transcripts at 48hr and 72hr. In addition, we noted considerable change to the hepatocyte transcriptome as a direct result of the isolation/plating procedure, regardless of the presence of HBV. Further pathway analysis of these differentially expressed transcripts identified many important cellular pathways, including those involved with cell cycle regulation and metabolism, as being differentially regulated by HBV in primary hepatocytes. mRNA profiles of cultured primary rat hepatocytes were generated, in triplicate, using the Illumina NextSeq 500 platform from freshly isolated cells (0hr), 24hr, 48hr, or 72hr after plating, and with or without expression of HBV 48hr or 72hr after plating.
Project description:Temproral networks of (phospho)-proteins are constructed and analyzed to infer differential interactions under insulin and IGF1 stimulation. In total, 134 antibodies are tested in 21 breast cancer cell lines. The experiments are done in triplicate. Three serum-free-condition time points (5min, 24hr, 48hr) and six stimulation time points (5min, 10min, 30min, 6hr, 24hr, and 48hr) are obtained with either 10 nM IGF1 or 10 nM insulin stimulation.

Project description:Humans are exposed to ionizing radiation (IR) from background radiation, medical treatments, occupational and accidental exposures. IR causes profound changes in transcription. Transcription is a primary process where protein amount and function can be regulated. One aspect of the transcriptional IR response that little is known about on a whole genome basis is alternative transcription. These investigations focus on the response to IR at the exon level in human cells but also at the whole gene level. Whole genome exon arrays were utilized to comprehensively characterize radiation-induced transcriptional expression products in two human cell types, namely EBV-transformed lymphoblast and primary fibroblast cell lines. Overall design: 12 human primary fibroblast cell lines and 12 primary lymphoblast cell line samples were used for two doses (0 and 10 Gy) and two time points (0 and 4hr). Additional doses ( 1 Gy, 2 Gy, 5 Gy, and 20 Gy) and time points ( 1hr, 2hr, 8hr, 24hr and 48hr) were assessed in four lymphoblast cell lines and four primary fibroblasts.
