Project description:It has been reported that PHF1, CUL4B and PRMT5 all play important roles in epigenetic regulation. We reported that PHF1, CRL4B and PRMT5 may act as a complex in transcriptional regulation and have a vital effect in breast cancer progression. So we performed ChIP-on-chip assays to find unique promoters co-targeted by PHF1, CUL4B and PRMT5. PHF1, CUL4B and PRMT5 have a predominant cooperation, at least in MDA-MB-231 cells. comparison of PHF1, CUL4B and PRMT5 target genes

Project description:Cullin 4B (CUL4B) is a scaffold protein of the CUL4B-Ring E3 ligase (CRL4B) complex. Here, we found that CRL4B interacted with transcriptional corepressor complexes. Our results supporting CUL4B as a potential target of cancer therapy.
Project description:Dicer, RNase III endonuclease, is an essential enzyme in miRNA biogenesis that regulates target gene expression, and it has been reported that aberrant expressions of Dicer associate with the clinical outcomes of patients in various cancers. To explore the miRNA differencial expression regulated by Dicer in MDA-MB-231/E1A cells, the microarray profiling analysis was employed to conduct differentially expressed miRNAs in stable MDA-MB-231/vector, MDA-MB-231/E1A, and MDA-MB-231/E1A/shDicer cells.
Project description:Identification of genes that are involved in self-seeding by comparing gene expression profiles between parental MDA-MB-231 cells and seeder cells (MDA-231-S1a and S1b) 2 replicates from each sample (parental MDA-MB-231, MDA-MB-231 S1a and MDA-MB-231 S1b) were analyzed

The four groups including vector control, E1A-expressing and Dicer knockdown in E1A-expressing MDA-MB-231 cells were harvested and RNA were isolated. Two independent experiments were performed for each group.

Project description:The project profiled the expression patterns in hypoxia induced secretomes between MDA-MB-231 parental and MDA-MB-231 Bone Tropic (BT) breast cancer cell lines which have been previously generated by Massague and colleagues (Kang et al. Cancer Cell 2003).
