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.

Gene expression profile upon TNF-a stimulation, forced expression of NICD, or TNF-a stimulation under forced expression of NICD, in human colon carcinoma-derived LS174T cells

Project description:A human colon carcinoma-derived cell line LS174T was modified to overexpress NICD, intracellular domain of Notch1, upon doxycycline addition (designated as LS174T-tetON-NICD cells), using the T-rex system (Invitrogen). We have previously shown that these cells can overexpress NICD under the control of CMV promoter (Okamoto R et al, Am J Physiol, 296(1):G23-35, 2009), and the amont of the overexpressed NICD protein reaches to the maximal level in early as 3 hours from doxycycline addition (100ng/ml), which persists for up to 24 hours. In the present experiment, LS174T-tetON-NICD cells were treated with recombinant human TNF-a (50ng/ml) alone, doxycycline alone (100ng/ml), co-treated by both TNF-a and doxycycline, or left untreated (Control) for 24 hours, and subjected for analysis. Experiment was done using a modified sub-line of LS174T cell (LS174T-tetON-NICD cells), in which overexpression of NICD can be induced by a Doxycycline dependent manner.

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.

Expression analysis of KHR and KHR-NICD oral tumors

Project description:KHR-NICD oral tumors grow faster than KHR oral tumors. The hypothesis was to test for differences in gene expression between KHR and KHR-NICD oral tumors. Total RNA was isolated for KHR (n=6) and KHR-NICD (n=6) oral tumors. Expression profiling was performed using the Illumina MouseRef-8 v2 (GPL6885) array. Studies were conducted using tumors from FVB x C57BL/6 F1 mice.

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.

Gene expression changes in Nicd induced wing disc hyperplasia

Project description:The outcome of Notch proliferation on proliferation depends on the context. In Drosophila wing imaginal discs Notch activation causes hyperplasia despite having localized inhibitory effects on proliferation. To understand te underlying mechanisms we have used genomic strategies to identify the Notch-Su(H) target genes during wing discs hyperplasis. these data are the results from expression profiling the RNAs from hyperplastic wing discs overexpressing Nicd. Direct comparison of third instar lavae wing imaginal disc Nicd (abxUbxFLPase; Act>y>Gal4, UAS GFP; FRT82B tubGal80 with UAS-Nicd; FRT82B) vs control (abxUbxFLPase; Act>y>Gal4, UAS GFP; FRT82B tubGal80 with FRT82B ). 4 Biological replicates, the 2nd replicate was performed as a dye-swap.
