Project description:Frequent loss of heterozygosity (LOH) at 11q22-23 in breast cancer strongly suggests that this region contains a tumor suppressor gene, yet to be identified. We and others have shown Yes-associated protein (YAP), which is located at 11q22.2, transactivates the p53 family member p73 upon DNA damage, suggesting a tumor suppressive function for YAP. Our analysis of breast tumor tissues by immunohistochemistry (IHC) showed loss of YAP protein expression in great portion of breast cancers. We used microarray to look at the targte genes regulated by YAP in normal breast luminal cell and breast cancer cell lines. Experiment Overall Design: We generated stable cell lines by introducing control vector(pRS-IRES-GFP/pmig) or YAP shRNA(pRS-IRES-GFP-YAP/pmig-YAP) in a normal breast luminal cell line 1089 luminal and breast cancer cell lines MDA MB231. RAN was extracted and hybridized on Affymetrix microarrays.We looked for new target genes regulated by YAP in normal breast luminal cell and breast cancer cell lines.

Project description:Experiments to test the effect of CtBP2 inhibition on metabolism of breast cell lines. In particular, experiment 1 involves comparison between a normal breast cell line (MCF102A) and a triple-negative breast cancer cell line (MDA-MB231). Experiment 2 is a study between MDA-MB231 silenced for CtBP2 by stable RNA interference (shCtBP2 cells) compared to scramble (shCTRL cells). Experiment 3 is a comparison between a normal breast cell line (MCF102A) and a triple-negative breast cancer cell line (MDA-MB231)in the presence of the absence of small-molecule CtBP inhibitors: HIPP (400 μM) or P4 (300 μM)for 48 hours.

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:Breast cancer brain metastasis has been recognized as one of the central issues in breast cancer research. Elucidation of the process and pathway that mediate this step is expected to provide important clues for a better understanding of breast cancer metastasis. Increasing evidence suggests that the aberrant glycosylation patterns greatly contribute to the cell invasion and cancer metastasis. Herein, we combined next generation RNA sequencing with liquid chromatograph-tandem mass spectrometry based proteomic and N-glycomic analysis from five breast cancer cell lines and one brain cancer cell line to investigate the possible mechanism of breast cancer brain metastasis. 24763 genes were identified including 14551 differentially expressed genes across six cell lines while proteomic analysis allowed the quantitation of 1096 differentially expressed proteins with approximately 83.8% proteins’ regulation matching their gene expression change. The genes/proteins associated with cell movement were highlighted in the breast cancer brain metastasis. Integrin signaling pathway and the up-regulation of α-integrin (ITGA2, ITGA3) associated with the brain metastatic process was shown through Ingenuity Pathway Analysis (IPA). Overall 91 glycosylation genes were selected from transcriptomic data and all exhibited differential expression. 12 glycogenes showed unique expression in 231BR. The regulation of these genes could result in an activation prediction of sialylation function in 231BR by ingenuity pathway analysis. In agreement with the changes of glycogenes, 60 N-glycans out of 63 identified exhibited differential expression among cell lines. The correlation of glycogenes and glycans revealed the importance of sialylation and sialylated glycans in breast cancer brain metastasis. Highly sialylated glycans, which were up-regulated in brain seeking cell line 231BR, probably contributes to brain metastasis.
