Project description:SUPT4H1 is a transcription elongation factor comprising part of the RNA polymerase II complex. Recent studies propose a selective role for SUPT4H1 in transcription of repeat-containing transcripts; the translated products of which being a hallmark of neurodegeneration in disorders such as Huntington’s Disease and C9orf72-amyotrophic lateral sclerosis. To investigate the potential of SUPT4H1 as a therapeutic target in repeat-associated neurodegeneration, we depleted SUPT4H1 by RNA interference in order to mimic pharmacological loss of function. Using RNA sequencing we assessed SUPT4H1-knockdown induced changes is both immortalized cells (HEK293t) as well as primary human fibroblasts. Diminished SUPT4H1 leads to a global reduction in cellular RNA.
Project description:We investigated gene expression profiles of Parkinson disease (PD) patient's fibroblasts that were treated by SNCA expression-control RNAi to see adverse effects of the RNAi treatment. The data suggested no significant adverse effects caused by the treatment.
Project description:This is part of a larger experiment in which the effects of IL-13, LIGHT and TGF-B1 on human primary esophageal fibroblasts were analyzed and compared.
Project description:We investigated gene expression profiles of Parkinson disease (PD) patient's fibroblasts that were treated by SNCA expression-control RNAi to see adverse effects of the RNAi treatment. The data suggested no significant adverse effects caused by the treatment. Total RNA samples prepared from PD fibroblasts that were treated by SNCA expression-control RNAi and by non-silencing RNAi as a control.
Project description:The Kaposi sarcoma-associated herpesvirus (KSHV) is the causative agent of Kaposi sarcoma (KS), the most common HIV/AIDS-associated tumor worldwide. Involvement of the oral cavity portends a poor prognosis for patients with KS, but mechanisms for KSHV regulation of the oral tumor microenvironment are largely unknown. Infiltrating fibroblasts are found with KS lesions, and KSHV establishes latent infection within human primary fibroblasts in vitro, but contributions for KSHV-infected fibroblasts to the KS microenvironment have not been previously characterized. In the present study, we used Illumina microarray to detect the global gene profile altered in KSHV-infected primary human fibroblasts (PDLF and HGF) isolated from the oral cavity.
Project description:This SuperSeries is composed of the following subset Series: GSE18952: Effects of IGF 1 on primary breast fibroblasts (normal and carcinoma associated) GSE18953: Effects of IGF 1 on MCF-7 breast cancer cells GSE18954: Effects of IGF 1 on CCL-171 fibroblasts Refer to individual Series
Project description:To characterize the effects of IGF 1 on primary breast fibroblasts, we cultured pre-starved primary breast fibroblasts (normal and carcinoma associated) from three patients with or without 50ng/ml IGF 1 for 24 h. We then profiled gene expression changes using Human Exonic Evidence Based Oligonucleotide (HEEBO) microarrays. After stimulation, total RNA was extracted and amplified using a modified Eberwine procedure. The amplified RNA was labeled with the fluorescent dye Cy5 and pooled with Cy3 labeled reference RNA, and then the pooled RNA was hybridized onto HEEBO microarrays. After hybridization and washing, arrays were scanned on a fluorescent microscope scanner.
