Project description:The study aims to elucidate the effect of histone methyltransferase SMYD3 on gene expression in MCF-7 breast cancer cell line. Knockdown luciferase control v.s. knockdown SMYD3 in MCF-7 breast cancer cell line were conducted. Results identify a large proportion of cell cycle-related genes regulated by SMYD3.
Project description:The breast cancer cell line MCF-7 was engineered to overexpress the Twist gene resulting in the MCF-7/Twist cell line. To study which miRNA are regulated by Twist, we employed whole genome microarray expression profiling and compared miRNA expression between MCF-7/Twist and MCF-7 cells.
Project description:We investigated the functions/pathways affected by SPEN knockdown in breast cancer by global expression profiling in a cell model, where the human breast cancer cell line, MCF-7, were transfected with an shRNA targeting SPEN mRNA.
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:Through the use of antagomiR-122, the knockdown of miR-122 was achieved with an efficiency of 70% in the cell line MCF-7RR with phenotype of acquired resistance to ionizing radiation. To evaluate the transcriptomic landscape resulting from knockdown of miR-122 of radioresistant breast cancer cells MCF-7RR. These assays showed the modulation of genes enrichment in RAS-MAPK and TNFR signaling pathways, inflammatory response and regulation of transcription.
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.
