Description
The goal of this study is to investigate the differential transcripted genes affected by CRISPR induced endoglin knockout in PASMC cells. Overall design: Total RNA was purified from NTC or ENG-/- PASMC cells using RNeasy Mini Kit (Qiagen, Hilden, Germany). RNA quality and concentration were assessed with Agilent Tapestation 200 (Agilent Technologies) and Qubit 2.0 (ThermoFisher Scientific). ~250-500 ng RNA were used for library construction. The NGS libraries were constructed using the KAPA Stranded mRNA-Seq Kits (KapaBioSystems). mRNA was captured using magnetic oligo-dT beads and 1st strand cDNA was synthesized using random priming. In order to preserve strand-specificity, 2nd strand synthesis, which converts the cDNA:RNA hybrid to double-stranded cDNA (dscDNA), was marked by dUTP incorporation. cDNA framents were A-tailed by adding dAMP to the 3''-ends of the dscDNA library fragments. dsDNA Illumina TruSeq "forked” adapters 3''-dTMP overhangs were then ligated to A-tailed library insert fragments. Each of the six libraries were ligated with a unique Truseq 6bp barcode. Library fragments were amplified using the KAPA HiFi HotStart polymerase. The strand marked with dUTP was not amplified, allowing strand-specific sequencing. Fragment length and library quality was assessed on a 2100 Bioanalyzer using the High Sensitivity DNA Kit (Agilent Technologies). Libraries were diluted to 10nM and pooled at equimolar ratios. The pool was then diluted to 2nM and denatured in NaOH following Illumina recommendations. 10pM of denatured library pool was loaded in one HiSeq lane and flowcell was clustered on the Illumina C-bot. 5% PhiX control was spiked-in. The flowcell was sequenced on a HiSeq 2500 V4 chemistry with 50bp Single read protocol. Data was demultiplexed and Fastq files were generated using BcptoFastq 1.8.4 script provided by Illumina.

Description
The objective of this experiment was to determine global gene expression change in triple negative cell line upon knockdown of TGFBR3. Genotype specific differences in expression profiles have been evaluated using human HuGene1.0-ST affymetrix array. RNA was extracted from SUM159 controls and SUM159 TGFBR3KD cells cultured in 3-dimensional in vitro system.

Description
To clarify the lineage relationship between IL3Rahigh- and IL3Ralow precursor cells and to find potential molecules involved in their differentiation, we compared the IL3Rahigh- and IL3Ralow precursor populations from three independent donors by mRNA deep sequencing and used the Ingenuity Pathway Analysis (IPA)- and Multi-experimental Viewer (MeV) to analyze the differentially expressed genes (p<0.001). Analysis of the protein coding genes showed that the samples from IL3Rahigh precursor cells clustered together, as did the IL3Ralow samples. This indicated that the gene expression patterns of these cells are likely to be conserved. Further analysis revealed a list of (649) differentially expressed molecules between the two populations. Among these, most notably, genes involved in the differentiation of cell in general, amongst which differentiation of MF, OC and antigen presenting cells appeared to be activation increased.

Description
The epithelial to mesenchymal transition (EMT) of malignant hepatocytes is a crucial event in hepatocellular carcinoma (HCC) progression and recurrence. We aimed to establish a human model of EMT to examine drug efficacy and specificity in HCC progression. Human HCC cell populations were characterized by immunofluorescence analysis, migration and invasion assays, array comparative genomic hybridization, whole-genome expression profiling and promoter methylation. Therapeutic agents clinically used against HCC were examined for efficacy by determination of IC50 values. Liver cancer cell lines showed either an epithelial or mesenchymal phenotype of which latter showed strong migratory and invasive abilities in vitro. The common cellular origin of both cell types indicated that mesenchymal HCC cells have been derived from epithelial hepatocytes through EMT in the HCC patient. Drug exposure of mesenchymal HCC cells showed higher resistance to the targeted therapeutic agents sorafenib and erlotinib as compared to epithelial HCC cells, which were slightly more resistant to cytostatic drugs. Most remarkably, combined treatment with doxorubicin and sorafenib caused increased susceptibility of both HCC cell types resulting in enhanced drug efficacy. Taken together, this novel model of human HCC allows to monitor the differential effect of liver cancer progression on drug efficacy in pre-clinical studies.
