Project description:We screened for target genes of hsa-mir-199a-1 and hsa-mir-4423 by transcriptome profiling. The miRNAs were overexpressed in HeLa cells by transient transfection of precursor miRNA expression plasmids. High-density Clariom D arrays for human were used for the gene expression analysis. This GEO entry provides the microarray data preprocessed according to the gene level workflow.
Project description:Microarray study of iBAT gene expression comparing a) adult male offspring of control and 3,3’,5-triiodothyronine (T3)-treated mothers during pregnancy and b) adult male offspring of control and maternal thyroid hormone receptor (TR) β signaling (TRb) treated mothers during pregnancy. Microarrays were conducted by Atlas Biolabs (Berlin, Germany) on GeneChip Clariom S arrays (Affymetrix/Thermofisher, Germany).
Project description:Experiment description to give context to the data set: Ductal carcinoma in situ (DCIS), the most common type of pre-invasive lesion of breast, is being detected with increasing frequency with the advent of mammographic screening. Surgery is the mainstay for the treatment of DCIS. Based on the clinic-pathological features of DCIS, this may be followed by radiotherapy and/or endocrine therapy. The qualitative assessment of histological grade, expression of single protein biomarkers and more recently, mRNA analysis (DCIS Score) have been used to make these decisions. However, these factors do not fully predict the likelihood of development of invasive breast cancer treated with breast-conserving surgery. A majority of women with ductal carcinoma in situ (DCIS) receive breast-conserving surgery (BCS) but then face a risk of development of invasive breast cancer. Using Human Clariom D Pico Assay, we aim to compare the transcriptome profiles of DCIS in relation to development of invasive breast cancer (INV-BC) versus Non-INV-BC cases. Experimental Methods Clariom D Pico Human Transcriptome Array were performed according to Applied Biosystems/Thermo Fisher Scientific’s instructions. Experimental protocols are summarized in detail in Supplementary Methods (Supplementary Data). Sample annotation We compared the relative gene expression in development of invasive breast cancer (INV-BC) versus Non-INV-BC cases in Singapore cohort-59 cases (discovery cohort) and Italian cohort-50 cases (validation cohort). Microplate Plate and Well IDs are also provided as Clariom D ID list per cohort. Author information Dr. Sunil Badve is the Principal Investigator. Raw Data Probe Cell Intensity (CELL) and .ARR files which contain the design information for this study are provided (Human Clariom D Pico Assay).
Project description:This study compares the dose dependent transcriptome data obtained for the volatile compound dimethylamine, which has been exposed in an in vitro system via air-liquid-interface (ALI) exposure to a pulmonary cell line (A549 cells).
