Description
Human SH-SY5Y neuroblastoma cells are widely utilized in in vitro studies to dissect out pathogenetic mechanisms of neurodegenerative disorders. These cells are considered as neuronal precursors and differentiate into more mature neuronal phenotypes under selected growth conditions. In this study, we performed systematic transcriptomic (RNA-seq) and bioinformatic analysis to pinpoint pathways and cellular processes underlying neuronal differentiation of SH-SY5Y cells according to a two-step paradigm: retinoic acid treatment followed by enriched neurobasal medium. Categorization of 1989 differentially expressed genes (DEGs) identified in differentiated cells outlined meaningful biological functions associated with changes in cell morphology including remodelling of plasma membrane and cytoskeleton, neuritogenesis. Seventy-three DEGs were assigned to Axonal Guidance Signalling pathway, and the expression of selected gene products such as neurotrophin receptors, the functionally related SLITRK6, and semaphorins, was validated by immunoblotting. Along with these findings, the differentiated cells exhibited the ability to elongate longer axonal process as assessed by the morphometric evaluation. Recognition of molecular events occurring in differentiated SH-SY5Y cells is necessary to accurately interpret the cellular responses to specific stimuli in studies on disease pathogenesis. Overall design: Comparison of cell line SH-SY5Y differentiated and undifferentiated.

Description
We created two cell lines derived from Ovcar8 by stably transfecting with an eGFP-firefly luciferase fusion protein and either an additional copy of the gene TWIST1 or an shRNA against TWIST1, under the control of the CMV promoter. RNA sequencing was used to look for differential expression of genes that may impact cisplatin resistance in epithelial ovarian cancer. Overall design: RNA-seq for differential expression between two cell lines differing in expression of gene of interest. Run as biological replicates and technical triplicates.
Publication Title
TWIST1 drives cisplatin resistance and cell survival in an ovarian cancer model, via upregulation of GAS6, L1CAM, and Akt signalling.

- Illumina HumanHT-12 V3.0 expression beadchip
Description
Genomic and expression profiling using 38K BAC array-CGH and Illumina HT-12 beadchips were performed on 97 diploid invasive breast tumors to assess the impact of gene dosage on gene expression patterns and the effect of other mechanisms on transcriptional levels. Patient stratification was performed according to axillary lymph node status (node-negative, pN0; node-positive, pN1) and overall survival (>8-year survivors; breast cancer-specific mortality within 8 years of diagnosis). Array-CGH results was validated by FISH using tumors showing HER2/neu gene amplification and expression profiling was confirmed using qPCR for 16 transcripts.

Description
Purpose: Analyze the function of the transcription factors Hand2 and Gata3 in adult sympathetic neurons by induced knockout and RNAseq analysis Overall design: Method and Result: Hand2flx/del::DbhCreERT2 (referred to as mutant) and Hand2flx/+::DbhCreERT2 (referred to a control) were injected for 10 days with tamoxifen to activate Cre. Animals were killed, sympathetic ganglia (SCG+Stellate) collected and processed for RNA isolation and RNAseq (Stanzel et al., 2016). Gata3flx/flx::DbhCerERT2 (mutant) and Gata3flx/+::DbhCreERT2 (controls) were treated as Hand2 animals. 16 ganglia from 4 mice were pooled for Hand2 mutant and controls and Gata3 controls. As only rudimentary ganglia were present in Gata3 mutant mice (Tsarovina et al., 2010) ganglia from 8 mice were pooled. The specific effects of the Hand2 knockout are decribed in Stanzel et al., 2016. The analysis of ganglion rudiments in the Gata3 knockout revealed that Gata3 was not reduced, indicating that the remaining cells had escaped the knockout.
