Expression data from wild type and ttk^twk mutant whole ovaries

ABSTRACT: Epithelial tube morphogenesis requires precise orchestration of cell signaling, shape, migration, and adhesion. Follicle cells in the Drosophila ovary form epithelial tubes, the lumens of which act as molds for the eggshell respiratory filaments, or dorsal appendages (DAs). The Tramtrack69 (TTK69) transcription factor controls DA lumen volume and shape by promoting tube expansion; the tramtrack mutation twin peaks (ttk^twk) reduces TTK69 levels late in oogenesis, inhibiting DA tube expansion. We used microarrays to identify differentially expressed genes in the ttk^twk mutant that are downstream of TTK69 and that play a functional role in DA tube expansion.

We used microarrays to identify differentially expressed genes in the ttk^twk mutant that are downstream of TTK69 and that play a functional role in DA tube expansion. Ovaries were dissected from female flies at 36 hours of age, to maximize the proportion of developing egg chambers undergoing DA tube expansion. Flies were raised at a constant temperature of 25C in the presence of wet yeast, to maximize the rate of egg chamber production.

A novel USP9X substrate TTK contributes to tumorigenesis in non-small cell lung cancer

Project description:The X-linked deubiquitinase, USP9X, is implicated in multiple cancers by targeting various substrates. Increased expression of USP9X is observed in non-small cell lung cancer (NSCLC) and is correlated with poor prognosis. However, the molecular mechanism for USP9X regulating tumor cell survival and tumorigenesis in NSCLC is less defined. In this study, chemical labeling quantitative proteomic screening was applied to analyze A549 cells with or without USP9X RNA interference, and the resulting data suggested that TTK is a potential substrate of USP9X. Further experimental evidences confirmed that USP9X stabilized TTK via direct interaction and deubiquitination of TTK. Moreover, knockdown of USP9X or TTK inhibited cell proliferation, migration and tumorigenesis, and the immunohistochemical analysis of clinical NSCLC samples showed that the protein expression levels of USP9X and TTK were significantly elevated and positively correlated in tumor tissues. In summary, our data demonstrated that the USP9X-TTK axis may play a critical role in NSCLC, and could be considered as the potential therapeutic target.

Candidate genes and pathways involved in TTK-induced biological functions in ovarian carcinoma

Project description:TTK has been shown to participate in the tumorigenesis of several cancer types but little is known about the function and molecular signalling in ovarian cancer cells. In this study we aim to identify the underlying mechanisms involved in TTK-induced biological functions in the human ovarian cancer cells.

Transcriptome profiling of Drosophila wild type and ttk-RNAi, dpn overexpressed, Nicd overexpressed and seq&Nicd overexpressed intestinal progenitor cells

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare transcriptome profiling (RNA-seq) of intestinal progenitor cells in Drosophila wild type and ttk-RNAi, dpn overexpressed, Nicd overexpressed and seq&Nicd overexpressed midguts Methods: mRNA profiles of intestinal progenitor cells isolated from 7-day-old wild-type (Ctrl) and ttk-RNAi, dpn overexpressed(dpn OE), Nicd overexpressed(Nicd OE) and seq&Nicd overexpressed(seq&Nicd OE) Drosophila midgut were generated by deep sequencing using Illumina HiSeq 2500. Results: ttk-RNAi in intestinal progenitor cells induces the expression of many neural-specific genes, including dpn and seq. Dpn ectopic expresion explains most of the ttk-RNAi expression profile change. Seq ectopic expression explains the expression of neural-specific Notch targets in the ttk-RNAi intestinal progenitor cells.

Transcription profiling of human mesenchymal stem cells transduced with lentivirus reporter gene fluc-mrfp-ttk

Project description:Human mesenchymal stem cells (hMSCs) were transduced using lentivirus containing the the triple fusion reporter gene fluc-mrfp-ttk. Microarray studies of hMSCs after transduction with the triple reporter genes using lentivirus were performed to study the effects of transduction on stem cell properties using an oligonucleotide human microarray. Transduced cells were sorted by FACS. Cells with high and low signals were ftacrtionated, and gene expression profiles were determined. Experiment Overall Design: In this study, 8 samples were experimentally evaluated. 2 samples were used as the control without undergoing any transduction. 2 samples were transduced with the virus containing only the backbone. 2 samples were transduced with the lentivirus containing the triple reporter and has high MGFP (>10^3), while 2 samples <10^3.

modENCODE_White Lab: genome-wide ChIP data of Ttk from Kc167 on Illumina Genome Analyzer.

Project description:This is a dataset generated by the Drosophila Regulatory Elements modENCODE Project led by Kevin P. White at the University of Chicago. It contains genome-wide binding profile of the factor Ttk from Kc167 generated by ChIP and analyzed on Illumina Genome Analyzer. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf A validated dataset is comprised of three biological replicates for ChIP-chip experiments and two replicates for ChIP-seq and meet the modENCODE quality standards. The control sample is the chromatin Input used for ChIP. Most factors binding profiles are generated by using specific antibodies for the protein of interest. However, some factors have been tagged by GFP in a transgenic line. In that case, ChIP is generated using an anti-GFP antibody. This submission represents the ChIP-seq component of the study.
