Project description:The transcription factor forkhead box D3 (FoxD3) is a transcriptional factor which belongs to forkhead box (Fox) transcription factor family. The functions of FOXD3 in embryogenesis and in the development of neural crest cells have been clearly defined. Its tumor suppressor function hasbeen found in many types of cancer in recent years. However, the study about its roles in lung cancerdevelopment is still lacking. Our study found that deficiency of FoxD3 in lung cancer enhanced cell growth and cell invasion. RNA-sequence analysis demonstrated that loss of FoxD3 mainly affected cell cycle progression related gene expression. Knockdown of FoxD3 led to G2-M cell accumulation with up-regulation of DNA replication licensing factor MCM5 and MCM4 as well as cell cycle regulator polo-like kinase-1 (PLK1) and CDC6. Over-expression of those genesin lung cancer was associated with poor clinical outcomes of lung cancer patients. We also identified high mobility group box-1(HMGB1), Hras and Ephrin B1 gene expression increase after FoxD3 silencing which may participate in enhanced lung cancer cell invasion. Our study identifiedtumor suppressor function of FoxD3 in lung cancer andwe did the first comprehensive analysis of the genes regulated by FoxD3 for cell proliferation and invasion in lung cancer. The identified genes regulated by FoxD3 through our analysis will provide valuable information to uncover the mechanism of FoxD3 tumor suppressor function.

Project description:The tumor-initiating cells (TIC) are cell population that can initiate tumor, mediate drug resistance, and give rise to metastasis. FOXD3 is a forkhead box (Fox) transcription factor family that regulates the pluripotency of embryonic stem cell and tumorigenicity. However, it is unclear whether FOXD3 play any role in TIC and tumor metastasis. Here, we report that FOXD3 is down-regulated in tumor initiating cells and negatively correlated with higher histologic grades and positive lymph node metastasis. FOXD3 repress TIC expansion, cell migration, drug resistance and osteogenesis in vitro and in vivo. Mechanically, we found that FOXD3 repress a cohort of genes including SET and WDR5 and to regulate several TIC related signaling pathway. Moreover, SET and WDR5 was positively correlated with the CSC abundance and tumor progression. Besides, patients with high expression of SET and WDR5 presented a poorer overall survival. Collectively, our work defined that FOXD3-WDR5-SET axis that repress TIC accumulation and lung cancer progression.

Project description:Neuroblastoma (NB), a malignant embryonic tumor arising from primitive neural crest cells, accounts for more than 7% of malignancies and around 15% of cancer-related mortality in childhood. Better elucidating the mechanisms of tumorigenesis and aggressiveness is important for improving the therapeutic efficiencies of NB. Through mining of publically available microarray datasets, we discovered a novel 963-bp lncRNA, named FOXD3 antisense RNA 1 (FOXD3-AS1), as an independent prognostic marker for favorable clinical outcome of NB patients. To investigate the mechanisms underlying the oncogenic functions of FOXD3-AS1, we employed the Illumina HiSeq PE125/PE150 as a discovery platform to analyze the transcriptome profiling changes of human BE(2)-C cells in response to stable over-expression of FOXD3-AS1. The results showed that stable over-expression of FOXD3-AS1 led to altered expression of 3191 human mRNAs, including 1542 up-regulated genes and 1650 down-regulated genes. Then we found the possible roles of these differentially regulated mRNAs in selected pathways including cell cycle/proliferation, apoptosis, and cytokine/chemokine responses by Bioinformatic analysis. Furthermore, we validated the RNA-seq results by real-time RT-PCR with high identity. Overall, our results provided fundamental information about the transcriptomic changes in response to FOXD3-AS1 over-expression in human NB cells, and these findings will help us understand the pathogenesis of NB.

Project description:We wished to examine the genes regulated by FoxD3 in pigment cells to gain understanding in how FoxD3 represses melanoblast specification in the neural crest. For technical reasons, we could not use neural crest cells, so we used melanoma cells, since they are derived from neural crest cells. To this end, we transfected B16-F10 mouse melanoma cells with constructs expressing FoxD3, or FoxD3-VP16, in which the C-terminal portion of FoxD3 (which contains the transcriptional repression domain) has been replaced by the VP16 transcriptional activation domain.

Project description:We describe the NucleoATAC algorithm for high-resolution nucleosome positioning and occupancy determination using ATAC-seq. ATAC-seq was performed on Saccharomyces cerevisiae and Schizosaccaromyces pombe. Nucleosomes were called for both species as well as for the human GM12878 cell line using data from GSE47753. Additionally, ATAC-seq was performed on S. cerevisiae undergoing an osmotic stress time-course and nucleosomes were called for each time point.

Experiment Overall Design: The base vector used for these studies was pMES, which expresses the gene of interest under control of the chick beta-actin promoter. EGFP is also expressed from the bicistronic mRNA through the use of an IRES. Experiment Overall Design: B16-F10 cells were transfected with either empty pMES, pFoxD3 (which contains FoxD3 inserted into pMES), or pFoxD3-VP16 (similar to pFoxD3, except that the C-terminal portion of FoxD3, which contains the transcriptional repression domain, has been replaced by the transcriptional activation domain of VP16). Experiment Overall Design: 24 hours after transfection, EGFP-positive cells were collected by FACS and those cells were subjected to microarray analysis.

Project description:In this study, we demonstrated that FOXD3, acting as a repressor in the expansion of lung cancer TICs, was negatively correlated with histological grades and metastasis in lung cancer, and provided evidence that FOXD3 repressed the TIC expansion, cell invasion and drug resistance in vivo and in vitro. Global genomic RNA-Seq and Chip-seq analyses identified WDR5 and SET as the direct targets of FOXD3 in lung cancer. Inhibition of WDR5 and SET could partially rescue TIC abundance, cell invasion, osteogenesis, and gene expression signature upon depletion of FOXD3. Clinically, we revealed that FOXD3 was negatively correlated with WDR5 and SET expression, CSC abundance, and prognosis of lung cancer.
