Project description:Transcriptomic profiling and unsupervised clustering of cMyc+ GC-B cells identify the four subpopulations representing positive-selection stages.
Project description:To determine functional overlap between cMyc and AP4 in CD8+ T cell priming, we retrovirally expressed cMyc or AP4 in cMyc-deficient CD8+ T cells and examined gene expression after activation.
Project description:cMyc and Max ChIP-seq analysis in a high MYC expressing small cell lung carcinoma cell line (H2171) and a low MYC expressing small cell lung carcinoma cell line (H128). H2171 cells (expressing high levels of cMyc protein) and H128 cells (expressing low levels of cMyc protein) were used to analyze how cMyc overexpression influences its genome-wide occupancy.
Project description:To determine functional overlap between cMyc and AP4 in CD8+ T cell priming, we retrovirally expressed cMyc or AP4 in cMyc-deficient CD8+ T cells and examined gene expression after activation. Naive CD8+ T cells from Myc conditional knockout mice with a tamoxifen inducible Cre transgene were retrovirally transduced with Myc or AP4 followed by a treatment with 4-hydroxytamoxifen in the presence of IL-7 for 2 days. RNA was harvested 48 hours after restimulation of transduced cells with anti-CD3 antibody and gene expression was compared by microarray. CD8+ T cells from littermate wildtype mice that were transduced with an empty retrovirus were used as control.
Project description:Transcriptome profiling of human umbilical vein endothelial cells (HUVECs) transduced with lentiviruses encoding FLAG-CAS9 nuclease and control- (gCTL) or cMYC-targeting (gMYC) gRNAS to identify cMYC regulated genes.
Project description:cMyc is a master regulator of transcription in growing cells. Here, we used microarray to study global transcriptomic expression of cMyc knockdown HT1080 cells to investigate cMyc- regulated gene expression.
