Project description:We studied genes, that are differentially expressed between malignant and normal breast tissue, to find weak spots for anti-cancer therapy development. RNA sequencing of three cell lines was performed: MCF-7 (epithelial breast cancer cell line), BCC (primary breast tumour cell line) and MCF-10A (epithelial breast cell line).
Project description:A comparison of different energetics based techniques for the characterization of two mammalian breast cell lines, MCF-7 a luminal A breast cancer cell line and MCF-10A a normal human breast cell line. The techniques of stability of proteins from rates of oxidation (SPROX), thermal proteome profiling (TPP), and conventional expression level analyses were compared and the relative advantages and disadvantages are discussed.
Project description:Genome wide expression profiling of breast normal cell line MCF-10A. The Illumina HumanHT-12 v4 Expression BeadChip was used to obtain expression profiles. This profiling indicates that MicroRNA-7 mediates the activity of HGF to suppress oncogenic proteins, which inhibits cancer progress.
Project description:We report differentially expressed genes by DATS exposure in MCF-10A human epithelial cell line and SK-BR-3 human breast cancer cell line
Project description:To explore the roles of essential miRNAs in regulating self-renewal of breast cancer stem cells (BCSCs), which initiate from mammary epithelial stem cells (MaSCs). CD44+CD24-/low cells and MUC1-ESA+ cells were isolated by fluorescence-activated cell sorting (FACS) from breast cancer cell line MCF-7 and normal mammary epithelial cell line MCF-10A, and were verified as BCSCs and MaSCs by clonogenic assay and multipotential differentiation experiment in 2-dimensional (2-D) and 3-D cultures, respectively. Using microarray containing oligonucleotides corresponding to 509 miRNAs from human, mouse, and rat genomes. We obtained candidate miRNAs in regulating breast tumorigenesis. One representative miRNA (miR-200c) was proved to regulate stemness of BCSCs and MaSCs in vitro and in vivo by miR-200c agomir transfection. We validated that miR-200c negatively regulated PDCD10, an apoptosis regulator, in BCSCs and MaSCs.
