Project description:Affymetrix microarray data was generated from MCF7 breast cancer cells treated in vitro with siRNAs against 78 transcription factors and signalling molecules. Gene expresion of 78 functionally important molecules were knocked down in MCF7 breast cancer cells using siRNA. Then the gene expression profiles of these MCF7 cells, along with untreated cells and non-targetting control (SICONTROL) treated cells were analysed using microarrays.
Project description:Affymetrix microarray data was generated from MCF7 breast cancer cells treated in vitro with siRNAs against estrogen receptor alpha (ESR1). Gene expresion of estrogen receptor alpha (ESR1) was knocked down in MCF7 breast cancer cells using siRNA. Then the gene expression profiles of these MCF7 cells, along with non-targetting control treated cells were analysed using Affymetrix Human Genome U133 Plus 2.0 microarrays.

Project description:LncRNA LINC01929 was knocked down using anti-LINC01929 antisense oligonucleotides (ASOs) in the ER+ breast cancer cell line MCF7 and the triple-negative breast cancer cell line MDA-MB-231.

Project description:Affymetrix microarray data were generated from A375 melanoma cells treated in vitro with siRNAs against 45 transcription factors and signalling molecules. 45 functionally important molecules were knocked down in A375 melanoma cells by siRNA. Then the gene expression profiles of these A375 cells, along with untreated cells and sRNA control treated cells were analysed by microarrays.
Project description:Analysis of tumor suppression by cell cycle-related genes which are regulated by SCTR(Secretin receptor) at gene expression level. The hypothesis tested in the present study was that SCTR regulates cell cycle-related genes toward tumor suppression in normal breast cells. Results suggest that normal breast cells have tumor suppressor activity when SCTR was knocked down by siRNA. Total RNA obtained from MCF-10A where SCTR was knocked down by siRNA
Project description:To investigate the function of SNHG14 in breast cancer, we established MDA-MB-231 cell lines in which this gene has been knocked down by siRNA.
Project description:The ets transcription factor ELF5 specifies the differentiation of mammary progenitor cells to establish the milk-secreting lineage. ER- and poor prognosis basal breast cancers arise from this progenitor cell and these cancers express high levels of Elf5. Knockdown of ELF5 expression in basal breast cancer cell lines, or forced expression in luminal breast cancer cell lines, resulted in reduced cell proliferation. Transcript profiling and chromatin immunoprecipitation revealed that the transcriptional activity of ELF5 specified the gene expression patterns that distinguish basal from luminal breast cancer, including suppression of FOXA1, GATA3 and ER, key estrogen-action genes. Tamoxifen treatment of luminal MCF7 cells upregulated Elf5 expression and cells that acquired resistance to Tamoxifen became dependent on ELF5 for proliferation. ELF5 is a regulator of breast cancer cell proliferation, transcriptionally specifies the basal molecular subtype and is utilised by ER+ breast cancer cells to escape proliferative arrest caused by Tamoxifen. Elf5 was knocked down via siRNA in basal HCC1937 cell lines, in triplicate. Elf5 was induced in luminal T47D and MCF7 cell lines via a doxycycline inducible expression vector, in duplicate.
