We recently reported that single-cell derived isogenic subclones of SKMEL5 cells have differential initial sensitivity to BRAF-inhibitors. In order to probe differences among these subclones, we selected three subclones with unique drug responses: progressing (SK-MEL-5 SC10), stationary (SK-MEL-5 SC07), and regressing (SK-MEL-5 SC01) and performed RNASeq. This study examines differentially expressed genes (DEGs) among the subclones to identify the molecular basis for initial differences in drug sensitivity. Overall design: Transcriptomics analysis between single-cell derived isogenic subclones of BRAF-mutated melanoma cell line, SK-MEL-5

Chromatinized protein kinase C-θ directly regulates inducible genes in epithelial to mesenchymal transition and breast cancer stem cells.

View SamplesEpithelial to mesenchymal transition (EMT) is activated during cancer invasion and metastasis, enriches for cancer stem cells (CSCs), and contributes to therapeutic resistance and disease recurrence. The epithelial cell line MCF7, can be induced to undergo EMT with the induction of PKC by PMA. 5-10% of the resulting cells have a CSC phenotype. This study looks at the transcriptome of these cells and how it differs from cells with a non-CSC phenotype.

View SamplesWe compared the seedling transcription profiles to determine the effects of loss-of-function of the BRX gene of Arabidopsis. BRX is required for optimal root growth. We compared seedlings of a loss-of-function line (brx) with its control background (Sav-0). Because the loss-of-function line was derived from introgression, a brx line that was complemented by a transgenic wild type copy of BRX was also included as a control. This line (rescued brx) allows the identification of expression differences that are due to introgression drag. See Mouchel et al. 2004, Genes & Dev. Vol. 18, p. 700 for a detailed description. We also compared to response of the different genotypes to the application of the phytohormones brassinolide (BL) and indole acetic acid (IAA)
BRX mediates feedback between brassinosteroid levels and auxin signalling in root growth.

View SamplesExpression profiling of mRNA abundance in the adult mouse olfactory epithelium during replacement of OSNs forced by the bilateral ablation of the olfactory bulbs. The experiment was done on 6 week old male C57Bl/6 mice. Olfactory epithelium tissue samples were collected on days 1, 5, and 7 after bulbectomy. The cellular processes activated by bulbectomy include apoptosis of mature olfactory sensory neurons, infiltration of macrophages and dendritic cells, stimulation of proliferation of basal cell progenitors, and differentation of new sensory neurons.

View SamplesPorcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of 3rd trimester pregnant pigs can result in transmission of the virus to the fetus and ultimately death in utero or postnatally. Little is known about the immune response to infection at the maternal-fetal interface and in the fetus itself, or the molecular events behind virus transmission and disease progression in the fetus. To investigate these processes, RNA-sequencing of two tissues, uterine endothelium adjacent to the umbilical attachment site and fetal thymus, was performed 21 days post challenge on four groups of fetuses selected from a large PRRSV challenge experiment of pregnant gilts. Overall design: RNA-seq experiment compared gene expression between four different groups of fetuses (n=12 per group): control (CON-uninfected fetuses from mock inoculated gilts), UNINF (uninfected fetuses from PRRSV-inoculated gilts), INF (infected fetuses from PRRSV-inoculated gilts), and meconium-stained fetuses (MEC-meconium-stained fetuses from PRRSV-inoculated gilts) and investigated two tissues: uterine endometrium (with adherent placental tissue) at the site of umbilical attachment and fetal thymus (96 samples in total). Three contrasts were performed for the differential expression (edgeR) and network (WGCNA) analyses: UNINF v CON, INF v UNINF, and MEC v INF.
