Project description:ChIP-seq analysis of SNAIL transcription factor binding sites in RH30 rhabdomyosarcoma cells

Project description:The main goal of the project was to analyze the effect of SNAIL transcription factor on microRNA expression profile in rhabdomyosarcoma (RMS) cells using the next generation sequencing. Differential expression of microRNAs between three groups was compared in RH30 alveolar RMS cells: WT (WT), shCTRL (modified with control shRNA vector) and shSNAIL (modified with shRNA against SNAIL). Different groups were compared to investigate the effect of SNAIL silencing on microRNA up- or downregulation.

Project description:Rhabdomyosarcoma (RMS) is a frequent non-epithelial tumor of soft tissue that originates from a myogenic differentiation defect. Expression of SNAIL transcription factor is elevated in the alveolar subtype of RMS, characterized by a low myogenic differentiation status and high aggressiveness. SNAIL affects RMS metastasis by reorganization of actin cytoskeleton, regulation of ezrin expression and chemotaxis to HGF and SDF-1. The differentiation of human RMS diminishes SNAIL level. SNAIL silencing completely abolishes the growth of human RMS xenotransplants. SNAIL inhibits myogenic differentiation of RMS by binding to the MYF5 promoter, suppressing its expression, displacing MYOD from canonical to alternative E-box sequences and regulating myomiRs expression. SNAIL silencing allows the re-expression of MYF5 and canonical MYOD binding, promoting RMS cell myogenic differentiation. These novel results open potential avenues for the development of innovative therapeutic strategies based on SNAIL silencing.

Project description:The effect of the Smac mimetic BV6 on the transcriptional regulation in the alveolar rhabdomyosarcoma cell line RH30 was investigated by bulk RNA-sequencing. To this end, RH30 cells were treated with 5 µM BV6 for 24 h, or left untreated. Here, a regulation of several NF-κB target genes could be observed.

Project description:Classical NF-κB activity can be inhibited by overexpression of the IκBα super repressor (SR). To determine the role of NF-κB in rhabdomyosarcoma cells, we overexpressed the IκBα SR in RH30 rhabdomyosarcoma cells. IκBα SR was overexpressed in RH30 cells. RH30 vector cells were used as control group.

Project description:Transcriptional profiling of mouse 4T1 breast cancer cells stably tranduced with pLEX-MCS based lentivirus. Three groups were compared, Vector cells, SNAIL expressing cells; and SNAIL+FBXO11 expressing cells. SNAIL expression induced strong EMT phenotype while SNAIL/FBXO11 reversed cells back to epithelial cells.

Project description:To screen the genes regulated by wt-Snail and non-acetylated Snail The successful development of cancer metastasis requires two major events: the reprogramming of cancer cells to increase their migration and tumor-initiation capabilities; and the remodeling of the tumor microenvironment to facilitate invasion and colonization of cancer cells. Epithelial-mesenchymal transition (EMT) is a crucial mechanism for reprogramming cancer cells to possess tumor initiation and migration capabilities1,2. However, the role of EMT in the interplay between tumor and host cells is largely unknown. The EMT regulator Snail is mainly known as a transcriptional repressor of the adhesion protein E-cadherin, whose repression is considered to be a key step in initiating metastasis3,4. We previously found that Snail can also act as an activator that induces the transcription of ERCC15 and IL86. Here we show that Snail is acetylated by CREB-binding protein (CBP) and that Snail and CBP co-occupy the promoters of target genes to activate transcription of the target genes. Furthermore, Snail activates the expression of a panel of cytokine genes, including TNFa (which forms a positive feedback loop with Snail to amplify the signal) and CCL2 and CCL5 (which facilitate the recruitment of macrophages by cancer cells). Our results demonstrate a novel function for Snail, providing new understanding of the recruitment of host cells to tumor sites during metastatic evolution.
