MDA-9/Syntenin regulates differentiation and angiogenesis programs in Head and Neck Squamous Cell Carcinoma

ABSTRACT: We identified MDA-9/Syntenin (8q12) as a key component of HNSCC differentiation and angiogenesis. Robust reduction in the expression of cyclinD1, CDK4, CTNNB1, STAT3 and PI3K were evident in MDA- 9/Syntenein depleted cells, which was reversed following MDA-9/Syntenin overexpression in immortalized oral epithelial cells. To further elucidate the role of MDA-9/Syntenin in tumor growth and epithelial cell differentiation in vitro and in vivo by sielnicng its expression.

Little is known about the molecular pathways regulating poor differentiation and invasion of head and neck squamous cell carcinoma (HNSCC). In the present study, we aimed to determine the role of MDA-9/Syntenin, a metastasis associated molecule in HNSCC tumorigenesis. Elevated MDA-9/Syntenin expression was evident in 67% (54/81) primary HNSCC tumors (p=0.001-0.002) and 69% (9/13) pre-neoplastic tissues (p=0.02-0.03). MDA-9/Syntenin overexpression was associated with the stage (p=0.001), grade (p ...[more]

Expression data of control-shRNA and SATB1-shRNA expressing MDA-MB-231 cells from 2D and 3D culture system

Project description:We examined whether SATB1 functions as a global gene regulator in order to maintain the aggressive phenotype of the MDA-MB-231 cell line. We compared the gene expression profiles between control_shRNA-MDA-MB-231 cells, which express SATB1 at high levels, and SATB1_shRNA1-MDA-MB-231 in which the level of SATB1 was greatly downregulated by RNAi technology. This comparative studies were performed using two different platforms (Codelink and Affymetrix genechip) with two culture conditions either on plastic dish (2D) or on matrigel (3D) which allows cells to form a breast-like morphology only for non-aggressive cells. Keywords: Comparative studies on Control_shRNA and SATB1_shRNA1 expressing MDA-MB-231 from 2D or 3D culture. We examined control_shRNA-MDA-MB-231 cells and SATB1_shRNA1-MDA-MB-231 cells under two culture condition;on plastic dish(2D culture) and on Matrigel coated dish(3D culture). When SATB1 was depleted by RNAi technology, these normally aggressive cells exhibited normal breast like morphology on 3D. We used two different microarray platforms (Codelink and Affymetrix) to make expression data. Initial analysis of data and cross-platform comparison were performed using Codelink expression analysis and GeneSpring software. We provide ratio for control_shRNA/SATB1_shRNA1-MDA-MB-231 cells for 2D and 3D on this series.

TWIST1-induced microRNA-424 drives an intermediate epithelial-to-mesenchymal transition that opposes metastasis

Project description:Epithelial-to-mesenchymal transition (EMT) is a dynamic process that relies on cellular plasticity; an EMT/MET axis is critical for metastatic colonization of carcinomas. Unlike epithelial programming, regulation of mesenchymal programming is not well understood in EMT. Here we describe the first microRNA that enhances exclusively mesenchymal programming. We demonstrate that microRNA-424 is up-regulated early during a TWIST1/SNAI1-induced EMT, and that it causes cells to express mesenchymal genes without affecting epithelial genes, resulting in a mixed/intermediate EMT. Further, microRNA-424 increases motility, decreases adhesion and induces a growth arrest, changes associated with a complete EMT. Patient microRNA-424 levels positively associate with TWIST1/2 and EMT-like gene signatures and is increased in primary tumors versus matched normal breast. However, microRNA-424 is down-regulated in metastases versus matched primary tumors. Correspondingly, microRNA-424 decreases tumor initiation and is post-transcriptionally down-regulated in macrometastases in mice. RNA-seq identified microRNA-424 regulates numerous genes associated with EMT and breast cancer stemness including the novel miR-424 target, TGFBR3, which regulates mesenchymal phenotypes without influencing miR-424 effects on tumor-initiating phenotypes; instead, we show that ERK signaling is critical for such tumor-initiating effects of miR-424. These findings suggest microRNA-424 plays distinct roles downstream of EMT-inducing factors, facilitating earlier stages, but repressing later stages, of metastasis. Examination of mRNA levels in MCF12A human breast cell lines that stably over-expressed miR-424 or an empty vector (EV) control. Each group has three replicates.

Minocycline is an inhibitor of the TNF-alpha induced fusion of human M13SV1-Cre breast epithelial cells and human MDA-MB-435-pFDR1 breast cancer cells

Project description:Using a Cre-LoxP-based cell fusion assay we able to demonstrate that the fusion of human M13SV1-Cre breast epithelial cells and human MDA-MB-435-pFDR1 breast cancer cells was induced by TNF-alpha both under normoxic and hypoxic conditions. To investigate the impact of TNF-alpha on the gene expression profile of the cells M13SV1 and MDA-MB-435-pFDR1 cells were cultured for three days in the presence of 100ng/ml TNF-alpha both under normoxic and hypoxic conditions. Untreated cells served as a control. Subsequently, total RNA was extracted from the cells. Total RNA of three independent experiments that matched RIN criteria of 8 to 10 was pooled. Synthesis and Cy3 labeling of cDNA and hybridization of microarrays and microarray analysis was performed by Source Biosciences (Nottingham, UK). Microarray gene expression data were analyzed using GeneSpring GX v14.8 software (Agilent Technologies).

DOCK1 gene derived hsa_circ_0020397 RNA is over-expressed in luminal mammary tumors and it is involved in the epithelial differentiation, growth and motility of the neoplastic cell

Project description:Circular-RNAs are an emerging group of regulatory molecules involved in the control of numerous cellular processes and may play a role in the growth and diffusion of various types of tumors. In the present study, we define the expression of 15 selected circular-RNAs, which may be involved in the process of epithelial-to-mesenchymal-transition, using a panel of 18 breast cancer cell-lines recapitulating the heterogeneity of the tumor and consisting of three distinct groups according to the mesenchymal/epithelial phenotype. The circular RNA deriving from the DOCK1 gene (hsa_circ_0020397) is characterized by the most interesting expression profile, as it is undetectable in triple-negative mesenchymal cell-lines, while it is easily measurable in epithelial cell-lines independent of their positivity to estrogen receptor or the HER2 membrane receptor. Whole-genome RNA-sequencing experiments performed on the triple-negative/mesenchymal MDA-MB-231 and MDA-MB-157 cell-lines engineered to over-express hsa_circ_0020397 demonstrate that the circular-RNA controls the expression of 110 common genes. Pathway analysis of these genes indicate that over-expression of the circular-RNA differentiates the two mesenchymal cell-lines along the epithelial pathway and increase cell-to-cell adhesion. This is accompanied by a growth inhibitory effect and a reduction in the random/directional motility of the two cell-lines. The up-regulated AGR2, ENPP1 and PPP1R9A genes as well as the down-regulated APOE, AQP3, CD99L2 and IGFBP4 genes show an opposite regulation by circDOCK1 silencing in CAMA1 luminal cells.

Isolation and characterization of a metastatic hybrid cell line generated by ER negative and ER positive breast cancer cells in mouse bone marrow

Project description:The origin and the contribution of breast tumor heterogeneity to its progression are not clear. We investigated the effect of a growing orthotopic tumor formed by an aggressive estrogen receptor (ER)-negative breast cancer cell line on the metastatic potential of a less aggressive ER-positive breast cancer cell line for the elucidation of how the presence of heterogeneous cancer cells might affect each other’s metastatic behavior. ER positive ZR-75-1/GFP/puro cells, resistant to puromycin and non-tumorigenic/non-metastatic without exogenous estrogen supplementation, were injected intracardiacally into mice bearing growing orthotopic tumors, formed by ER negative MDA-MB-231/GFP/Neo cells resistant to G418. A variant cell line B6, containing both estrogen-dependent and -independent cells, were isolated from GFP expressing cells in the bone marrow and re-inoculated in nude mice to generate an estrogen-independent cell line B6TC.
