E2f8 mediates tumor suppression in postnatal liver development.
Age, Specimen part
View SamplesE2Fs are regulators of the cell cycle and are involved in development. In this study we examine transcriptional changes occurring the liver in E2f1 (1KI) and E2f3b (3bKI) knock in mice. These mice have E2f1 or E2f3b knocked into the E2F3a locus resulting in loss of E2f3a and expression of E2f1 or E2f3b from the E2f3a locus as originally described In Tsai et. al., Nature 2008.

View SamplesThis portion of the study evaluated the effects of topical 10% black raspberry gel application on gene expression profiles of premalignant oral lesions. Topical application of the bioadhesive black rasberry gel was observed to modulate gene expression and reduce proinflammatory proteins in human premalignant oral lesions.

View SamplesWe show that numerous miRNAs are transcriptionally up-regulated in papillary thyroid carcinoma (PTC) tumors compared with unaffected thyroid tissue. Among the predicted target genes of the three most upregulated miRNAs (miRs 221, 222 and 146b), only less than 15% showed significant downexpression in transcript level between tumor and unaffected tissue. The KIT gene which is known to be downregulated by miRNAs 221 and 222 displayed dramatic loss of transcript and protein in those tumors that had abundant mir-221, mir-222, and mir-146b transcript.

View SamplesPapillary thyroid cancers (PTC) that invade into local structures are associated with a poor prognosis, but the mechanisms for PTC invasion are incompletely defined limiting the development of new therapies. To characterize biological processes involved in PTC invasion, we analyzed the gene expression profiles of microscopically dissected intratumoral samples from central and invasive regions of seven widely invasive PTCs and normal thyroid tissue by oligonucleotide microarray and performed confirmatory expression and functional studies. In comparison to the central regions of primary PTCs, the invasive fronts overexpressed TGFbeta, NFkappaB and integrin pathway members, and regulators of small G-proteins and CDC42. Moreover, reduced levels of mRNAs encoding proteins involved in cell-cell adhesion and communication were identified, consistent with epithelial-to-mesenchymal transition (EMT). To confirm that aggressive PTCs were characterized by EMT, 35 additional PTCs were examined for expression of vimentin, a hallmark of EMT. Overexpression of vimentin was associated with PTC invasion and nodal metastasis. Functional, in vitro studies demonstrated that vimentin was required for the development and maintenance of both a mesenchymal morphology and invasiveness in thyroid cancer cells. We conclude that EMT is a common mechanism of PTC invasion and that vimentin regulates thyroid cancer EMT in vitro.

View SamplesIn current study, DES could effectively suppress the expression of miR-9-3 through the ERa-dependent epigenetic machinery in MDECs and MCF-7 cells. We want to figure out the biological significance and the potential targets of miR-9-3 and the related signaling cascades.
