Gene expression profiling of CTCL patient-derived cell lines after GTSF1 knockdown

Project description:In CTCL, the ectopic expression of Gametocyte Specific Factor 1 (GTSF1) has emerged as a potential prognostic biomarker. High expression of GTSF1 has been associated with a worse overall prognosis for patients. However, the contribution of GTSF1 to CTCL carcinogenesis remains unknown. We performed a shRNA mediated silencing of GTSF1 in three cell lines representing the most common variants of CTCL: Mac2A, representative of primary cutaneous Anaplastic Large Cell Lymphoma; MyLa 2000, representative of Mycosis Fungoides; and SZ4, representative of Sézary Syndrome. The three cell lines showed different gene expression profiles, signaling the different clinical behaviors of each variant. In Mac2A, silencing of GTSF1 in CTCL led to T cell activation and production of IFNγ and TNFα. This suugests that GTSF1 contributes to carcinogenesis by partially modifying the effector-memory phenotype of the malignant T cells.

Drosophila Gtsf1 is an essential component of the Piwi mediated transcriptional silencing complex

Project description:The PIWI interacting RNA pathway is a small RNA silencing system that keeps selfish genetic elements such as transposons under control in animal gonads. Several lines of evidence indicate that nuclear PIWI family proteins guide transcriptional silencing of their targets, yet the composition of the underlying silencing complex is unknown. Here we demonstrate that the double CHHC zinc finger protein Gtsf1 is an essential factor for Piwi mediated transcriptional repression in Drosophila. Cells lacking Gtsf1 contain nuclear Piwi loaded with piRNAs, yet Piwi's silencing capacity is ablated. Gtsf1 interacts stably with a sub-population of nuclear Piwi and loss of Gtsf1 phenocopies loss of Piwi in terms of deregulation of transposons, loss of H3K9me3 marks at euchromatic transposon insertions and deregulation of genes in proximity to repressed transposons. We propose that only a small fraction of nuclear Piwi interacts productively with a target RNA, resulting in assembly of a silencing complex with Gtsf1 as one core component. impact of loss of DmGtsf1 on transcription and H3K9m3 in ovarian somatic cells (OSC)

Expression data from CTCL patient skin lesion [Agilent]

Project description:Cutaneous T cell lymphoma (CTCL) can have clinical and histological features resembling benign inflammatory dermatosis (BID) and can be difficult to diagnose especially at the early stage of CTCL. We used microarrays to detail the global alteration of miRNA transcriptome and generate a diagnosis and prognosis signature.

Oncogenic role of TOX in CTCL

Project description:TOX is a nuclear factor essential for the development of CD4+ T cells in the thymus. TOX is found to be aberrantly up-regulated in the skin biopsies and in the blood CD4+ T cells of cutaneous T cell lymphoma. The goal of this study is to identify potential transcriptional targets of TOX in CTCL by comparison between TOX shRNA transfected CTCL cells (Hut78 and HH) and control CTCL cells. Two color experiment. Lentivirus transduced control vector vs. TOX shRNA vectors on Hut78 and HH cell lines. Biological replicates: 3 control replicates, 3 shRNA tansduced replicates for each cell line.

RIP-seq of mouse Asterix/Gtsf1 expressed in Sf9 cells

Project description:Asterix/Gtsf1 has been previously been shown to be involved in the silencing of retrotransposons in animal germ cells through the piRNA pathway. During early stages of purification of mouse Gtsf1 protein in Sf9 cells for structural studies, we found that the protein was co-purifying with endogenous nucleic acids. We first characterized those RNAs by next-generation sequencing (this dataset) and then later investigated its RNA-binding in more relevant cell culture systems. In each case, we found Asterix/Gtsf1 was binding tRNAs. Given the role of tRNAs as primers for Long Terminal Repeat (LTR) transposons, this work implicates Asterix/Gtsf1 as exploiting tRNA dependence to identify transposon transcripts and promote piRNA silencing.
