The mechanisms coupling fate specification of tissues to their physical separation remain largely unknown. mammalian trachea and esophagus differentiate from a single tube definitive endoderm, requiring the mutually repressive transcription factors SOX2 NKX2-1, but how dorsoventral site tissue is defined properly allocate tracheal esophageal cell types Here, we show that EPH/EPHRIN signaling ge...

In this study we have performed genome-wide analysis to identify Nkx2-5 binding regions using mid-gestation mouse hearts to gain insight into the molecular mechanisms by which Nkx2-5 contributes to the correct development of the heart. Nkx2-5 and SRF invivo binding sites were mapped using ChIPchip assays and analysis of the ChIP-chip data has identified 600 and 858 SRF and Nkx2-5-binding sites,...

NKX2-1, encoding a homeobox transcription factor, is amplified in approximately 15% of non-small cell lung cancers (NSCLC), where it is thought to drive cancer cell proliferation and survival. However, its mechanism of action remains largely unknown. To identify relevant downstream transcriptional targets, here we carried out a combined NKX2-1 transcriptome (NKX2-1 knockdown followed by RNAseq)...

The NKX2-1 transcription factor, a regulator of normal lung development, is the most significantly amplified gene in human lung adenocarcinoma. To study the transcriptional impact of NKX2-1 amplification, we generated an expression signature associated with NKX2-1 amplification in human lung adenocarcinoma and analyzed DNA-binding sites of NKX2-1 by genome-wide chromatin immunoprecipitation. In...

BACKGROUND NKX2-1, a key molecule in lung development, is highly expressed in non-small cell lung cancer (NSCLC), particularly in lung adenocarcinoma (ADK), where it is a diagnostic marker. Studies of the prognostic role of NKX2-1 in NSCLC have reported contradictory findings. Two microRNAs (miRNAs) have been associated with NKX2-1: miR-365, which targets NKX2-1; and miR-33a, which is downstrea...

Nkx homeobox transcription factors are expressed in diverse embryonic cells and presumably control cell-type specification and morphogenetic events. Nkx2-9 is a novel family member of NK2 genes which lacks the conserved TN-domain found in all hitherto known murine Nkx2 genes. The prominent expression of Nkx2-9 in ventral brain and neural tube structures defines a subset of neuronal cells along ...

The homeodomain transcription factor Nkx2-1 is essential for normal lung development and homeostasis. In lung tumors, it is considered a lineage survival oncogene and prognostic factor depending on its expression levels. The target genes directly bound by Nkx2-1, that could be the primary effectors of its functions in the different cellular contexts where it is expressed, are mostly unknown. In...
