Project description:Comparing the transcriptomic profiles of GBM-37 cells treated with control and NUPR1 v.1 siRNA. Goal was to examine the effects of NUPR1 v.1 on malignant mesenchymal transformation of GBM tumor after conventional treatment
Project description:Transcriptional profiling of human hTERT-RPE1 cell spheroids comparing Control siRNA transfected hTERT-RPE1 cell spheroids with those transfected with YAP1 siRNA.
Project description:Finding a novel prognostic marker and therapeutic target for aggressive GBM is necessary. By analyzing pre- and post-treatment tumors from a GBM patient who experienced a very aggressive tumor recurrence after receiving concurrent chemoradiotherapy with temozolomide, we discovered a novel prognostic marker for aggressive mesenchymal GBM
Project description:Transcriptional profiling of HCT116 cells compared to untreated control with HCT116 cells transfected with ZNF746 siRNA plasmid. Goal was to determine the effects of ZNF746 gene transfection on CRC progression. Two-condition experiment, HCT116 vs. ZNF746 siRNA.
Project description:Transcriptional profiling of human hTERT-RPE1 cell spheroids comparing Control siRNA transfected hTERT-RPE1 cell spheroids with those transfected with YAP1 siRNA. Two-condition experiment, Control siRNA vs.YAP1 siRNA hTERT-RPE1 cell spheroids. Biological replicates: 1 Control siRNA, 1YAP1 siRNA transfected, independently grown and harvested. Bothreplicates per array.
Project description:Twenty million LbetaT2 cells were transfected with either control or Galphas siRNA, then were seeded in 100-mm cell culture plates in DMEM + 10% FBS. Two days later, cells were washed twice with pre-warmed PBS. Conditioned media was harvested another 24 h later, and centrifuged at 20,000 g for 10 min at 4°C to remove cell debris. To enrich secreted proteins in the conditioned media, conditioned media samples were centrifuged using Amicon centrifugal filters with a 3kDa cutoff (Millipore, Billerica, MA). A total of 8 concentrated conditioned media samples were independently prepared: 4 samples from control siRNA-treated cells, and 4 samples from Galphas siRNA-treated cells. Samples were stored at –70°C until they were sent to the Mount Sinai Proteomics Core Facility.HPLC-isobaric tags for relative and absolute quantitation mass-spectrometry (iTRAQ MS) - Data analysis ProteinPilot 3.0 (AB Sciex) was used to search the MS/MS spectra for protein identification and quantitation with its searching algorithm Paragon 3.0.0.0 (*Reference). The protein database used for searching was Uniprot mouse fasta file (release-2010_11). The search parameters include quantitation for iTRAQ 8-plex (peptide-labeled), MMTS for cysteine alkylation, trypsin for enzyme digestion, biological modifications for ID focus, and taxonomy set for Mus musculus. The detected protein threshold was set to 1.3 (95% confidence). Additionally, we converted our AB Sciex mass spectral data (TOF/TOF data) into an mzML format, using the AB Sciex MS Data Converter (beta version 1.3) tool. Finally, we used the command line tool group2xml, which is included with ProteinPilot Software, to convert the .group search engine result file to an XML file.
Project description:To clarify the effect of SHP in LXRs-mediated signaling pathway, we performed global gene expression analysis of SHP siRNA transfected- or control siRNA transfected- astrocytes after IFN-γ and LXRs agonist. Microarray analysis revealed that expression of several genes encoding inflammatory mediators were reversed in SHP siRNA transfected-astrocytes, when compared with control siRNA transfected-astrocytes.
