Description
The HMG-box factor Tcf1 is required during T-cell development in the thymus and mediates the nuclear response to Wnt signals. Tcf1/ mice have previously been characterized and show developmental blocks at the CD4CD8 double negative (DN) to CD4+CD8+ double positive transition. Due to the blocks in T-cell development, Tcf1/ mice normally have a very small thymus. Unexpectedly, a large proportion of Tcf1/ mice spontaneously develop thymic lymphomas with 50% of mice developing a thymic lymphoma/leukemia at the age of 16 wk. These lymphomas are clonal, highly metastatic, and paradoxically show high Wnt signaling when crossed with Wnt reporter mice and have high expression of Wnt target genes Lef1 and Axin2. In wild-type thymocytes, Tcf1 is higher expressed than Lef1, with a predominance of Wnt inhibitory isoforms. Loss of Tcf1 as repressor of Lef1 leads to high Wnt activity and is the initiating event in lymphoma development, which is exacerbated by activating Notch1 mutations. Thus, Notch1 and loss of Tcf1 functionally act as collaborating oncogenic events. Tcf1 deficiency predisposes to the development of thymic lymphomas by ectopic up-regulation of Lef1 due to lack of Tcf1 repressive isoforms and frequently by cooperating activating mutations in Notch1. Tcf1 therefore functions as a T-cellspecific tumor suppressor gene, besides its established role as a Wnt responsive transcription factor. Thus, Tcf1 acts as a molecular switch between proliferative and repressive signals during T-lymphocyte development in the thymus.

Illumina HiSeq 2500
Description
Purpose: The intergration of genetic and chemical screens identified SETD8 as a new druggable target in neuroblastoma tumor. The goal of this study is to evaluate the transcriptome profiling (RNA-seq) of Neuroblastoma cell lines after genetic and pharmacological inhibition of SETD8. Methods: mRNA profiles of NB cells after genetic and pharmacological inhibition of SETD8 were generated by deep sequencing in duplicate with Ilumina HiSeq2500 using Illumina TruSeq V4. The sequence reads were analyzed with software Trimmomatic, STAR and edgeR to determine the differetially expressed genes. qRT–PCR validation was performed using SYBR Green assays. Results: About 60 million sequence reads per sample were mapped to the human genome (hg19). Approximately 10% of the transcripts showed differential expression between the control and the treated samples, with a fold change =1.5 and p value <0.05. Altered expression of 12 genes was confirmed with qRT–PCR, demonstrating the high degree of sensitivity of the RNA-seq method. Hierarchical clustering of differentially expressed genes uncovered several as yet uncharacterized genes that may contribute to SETD8 function. Conclusions: Our study identifies SETD8 as a new therapeutic target in Neuroblastoma tumor. RNA-seq transcriptome analyses and functional studies revealed that SETD8 ablation rescued the proapoptotic and cell-cycle arrest functions of p53 through reactivation of the p53 canonical pathway by decreasing p53k382me1. Overall design: mRNA profiles of Neuroblastoma cells after genetic and pharmacological inhibition of SETD8 were generated by deep sequencing in duplicate with Ilumina HiSeq2500 using Illumina TruSeq V4.
