Expression data of human lung adenocarcinoma cell line H441 treated with TTF-1/NKX2-1 siRNA and TGF-beta

ABSTRACT: We determined and analyzed the effect of TTF-1/NKX2-1 on Smad3/Smad4 binding sites by ChIP-sequencing. We used expression microarrays to evaluate the effect of TTF-1/NKX2-1 siRNA on TGF-beta-induced gene expressions. H441 cells were transfected with siRNAs and treated with TGF-beta for RNA extraction and hybridization on Affymetrix microarrays. This submission represents transcriptome component of study.

Thyroid transcription factor-1 (TTF-1, also known as NKX2-1) is a tissue-specific transcription factor in lung epithelial cells. Although TTF-1 inhibits the epithelial-to-mesenchymal transition induced by transforming growth factor-β (TGF-β) in lung adenocarcinoma cells, the mechanism through which TTF-1 inhibits the functions of TGF-β is unknown. Here we show that TTF-1 disrupts the nuclear Smad3-Smad4 complex without affecting the nuclear localization of phospho-Smad3. Genome-wide analysis by ...[more]

Expression data of the human hepatoblastoma cell line HepG2 treated with TGF-beta

Project description:Smad2/3 are transcription factors that engage in TGF-beta-induced transcription. We determined and analyzed HepG2 and Hep3B-specific Smad2/3 binding sites by ChIP-chip. We used expression microarrays to compare the Smad2/3 and HNF4alpha binding sites identified by ChIP-chip or ChIP-seq, respectively, to TGF-beta-induced gene expressions. HepG2 cells were transfected with control or HNF4A siRNAs and treated with 3 ng/ml TGF-beta for 0, 1.5 and 24 h (6 samples in total, no replicates). Total RNA was extracted and expression microarray analysis was performed as described in the protocols.

Transcription profiling of human bronchial epithelial cells overexpressing the lung developmental transcription factors TTF1, NKX2-8 and PAX9

Project description:We investigated the clinical implications of lung developmental transcription factors (TTF-1, NKX2-8, and PAX9) which we recently discovered as cooperating oncogenes activated by way of gene amplification at chromosome 14q13 in lung cancer. Using stable transfectants of human bronchial epithelial cells, RNA expression profiles (signatures) representing activation of the biological pathways defined by each of the three genes were determined and used to risk stratify a non-small cell lung cancer (NSCLC) clinical dataset consisting of ninety-one early stage tumors. Co-activation of the TTF-1 and NKX2-8 pathways identified a cluster of patients with poor survival, representing approximately 20% of patients with early stage NSCLC, whereas activation of individual pathways did not reveal significant prognostic power. Importantly, the poor prognosis associated with co-activation of TTF-1 and NKX2-8 was validated in two other independent clinical datasets. Further, lung cancer cell lines showing co-activation of the TTF-1 and NKX2-8 pathways were shown to exhibit resistance to cisplatin, the standard of care for the treatment of NSCLC. Since TTF-1 and NKX2-8 lack specific inhibitors at the current time, we explored an alternative therapeutic strategy. Using signatures of signaling pathway activation, we identified deregulation of specific oncogenic pathways (Ras and Myc) in the TTF-1/NKX2-8 co-activated cohort. In vitro experiments demonstrated the ability of a Ras pathway-specific therapy to inhibit tumor cell growth in TTF-1/NKX-2 activated cells, thus, suggesting that modulation of the Ras pathway is a rational strategy to targeted therapy in high risk NSCLC patients with co-activation of specific lung developmental pathways. Experiment Overall Design: Six controls and six replicates of each transcription factor (TTF1, NKX2-8, PAX9) were prepared and analyzed.
