Naa10p's effect on gene expression profiles in MCF7 breast cancer cells

ABSTRACT: N-α-acetyltransferase 10 protein (Naa10p, also called ARD1), the catalytic subunit of N-acetyltransferase A, is a critical regulator of cell death and proliferation. Naa10p is also shown to regulate cancer metastasis by inhibiting cell motility, however its role in cancer metastasis is not fully understood. In this study, we found that high expression of Naa10p is positively correlated with the survival of patients with breast cancer, while negatively correlated with lymph node metastasisr. Naa10p inhibits breast cancer cell migration and invasion in vitro and decreases the xenograft growth and metastasis in nude mice. Microarray screening revealed that Naa10p down-regulates expression of several pro-invasive genes, which was validated by qRT-PCR analysis.

Naa10p's effect on gene expression profiles in MCF7 breast cancer cells

Project description:N-?-acetyltransferase 10 protein (Naa10p, also called ARD1), the catalytic subunit of N-acetyltransferase A, is a critical regulator of cell death and proliferation. Naa10p is also shown to regulate cancer metastasis by inhibiting cell motility, however its role in cancer metastasis is not fully understood.

Naa10p inhibits breast cancer cell migration and invasion in vitro and decreases the xenograft growth and metastasis in nude mice. Microarray screening revealed that Naa10p down-regulates expression of several pro-invasive genes, which was validated by qRT-PCR analysis. To gain an insight into Naa10p’s inhibitory effect on cancer metastasis, we performed microarray analysis with RNA samples extracted from Naa10p-silenced MCF-7 (MCF-7SA) and control cells (MCF-7NC).

Explore the role of RHAMM in invasion/metastasis of breast cancer

Project description:To understand the mechanism of breast cancer invasion and metastasis, we collected tumor tissue from a cohort of 120 breast cancer patients and performed a Nanostring gene profiling assay (26 cases were removed from further analysis during quality control). Differential gene expression (DGE) analysis was done by comparing patients with/without lymph node metastasis lymph nodes. To explore the role of RHAMM in breast cancer invasion and metastasis, we created an RHAMM Related Signature (RRS) by intersecting the top 50 genes with another DGE list generated from a murine model wherein overexpression of an oncogenic RHAMM isoform increased cell motility in vivo tumor engraftment, and metastasis to identify RHAMM-related transcriptome changes specifically.

Identification of recurrence biomarkers in over 40 year’s women with lymph-node-positive primary breast cancer

Project description:Several studies provide genes expression characteristic correlated to recurrence in breast cancer patients with lymph node negative. However few reports mentioned about the gene expression file in patients with lymph node metastasis confirmed during surgery, of which the cumulative incidences of relapse are more than 50%.

Prognostic value of biomarkers EpCAM and B-crystallin is associated with lymphatic metastasis in breast cancer by iTRAQ analysis

Project description:Metastasis is responsible for the majority of deaths in a variety of cancer types, including breast cancer. Although several factors or biomarkers have been identified to predict the outcome of patients with breast cancer, few studies have been conducted to identify metastasis-associated biomarkers. Quantitative iTRAQ proteomics analysis was used to detect differentially expressed proteins between lymph node metastases and their paired primary tumor tissues from 23 patients with metastatic breast cancer. Immunohistochemistry was performed to validate the expression of two upregulated (EpCAM, FADD) and two downregulated (NDRG1, αB-crystallin) proteins in 190 paraffin-embedded tissue samples. These four proteins were further analyzed for their correlation with clinicopathological features in 190 breast cancer patients. We identified 637 differentially regulated proteins (397 upregulated and 240 downregulated) in lymph node metastases compared with their paired primary tumor tissues. Furthermore, bioinformatics analysis using GEO profiling confirmed the difference in the expression of EpCAM between metastases and primary tumors tissues. Two upregulated (EpCAM, FADD) and two downregulated (NDRG1, αB-crystallin) proteins were associated with the progression of breast cancer. Obviously, EpCAM plays a role in the metastasis of breast cancer cells to the lymph node. We further identified αB-crystallin as an independent biomarker to predict lymph node metastasis and the outcome of breast cancer patients.

Pilot Study 13C flux effects when RhoC or RhoA perturbed (13C BCs)

Project description:Rho-GTPases are small GTP-binding proteins that contribute to the epithelial-to-mesenchymal transition by regulating several cellular processes including organization of the actin cytoskeleton, cell motility, transcription, and cell proliferation. Overexpression of RhoC-GTPases (RhoC) in breast cancer has been implicated in poor disease prognosis due to increased cancer cells invasion, migration, and motility, which warranted its consideration as a therapeutic target for inhibiting breast cancer metastasis. Using silencing RNA (siRNA) molecules to knockdown RhoC expression is a promising approach to inhibit breast cancer metastases.

Expression data from Control and Six1 expressing MCF7 derived xenograft tumors

Project description:Although an important association between lymph node metastasis and poor prognosis in breast cancer was observed decades ago, an active role for the lymphatic system in metastatic dissemination has only recently been examined. We demonstrate that the Six1 homeoprotein promotes peri- and intra-tumoral lymphangiogenesis, lymphatic invasion, and distant metastasis of breast cancer cells. We identify the pro-lymphangiogenic factor, VEGF-C, as required for this process, and demonstrate transcriptional induction as the mechanism of regulation of VEGF-C expression by Six1. Using a different, but complementary animal model, we show that while required, VEGF-C is not sufficient for the pro-metastatic effects of Six1. Verifying the clinical significance of this pro-metastatic Six1-VEGF-C axis, we demonstrate co-expression of Six1 and VEGF-C in human breast cancer.

Plasma proteomic profiling of small size HER2-positive breast cancer

Project description:Lymph node status is a crucial predictor for the overall survival of invasive breast cancer. However, lymph node involvement is only detected in about half of HER2 positive patients. Currently, there are no biomarkers available for distinguishing small size HER2-positive breast cancers with different lymph node statuses. Thus, in the present study, we applied label-free quantitative proteomic strategy to construct plasma proteomic profiles of ten patients with small size HER2-positive breast cancers (5 patients with lymph node metastasis versus 5 patients with lymph node metastasis).

Whole-transcriptome analysis in breast cancer with or without lymph node metastasis

Project description:To identify the mRNAs, long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) involved in the pathogenesis of breast cancer, we performed the whole transcriptome sequencing. The whole transcriptome sequencing was performed with three breast cancer tissues with or without lymph node metastasis in each group, respectively. The results showed that 728 mRNAs, 131 lncRNAs, and 144 circRNAs were differentially expressed in lymph node metastasis group and no lymph node metastasis group (fold change≥2, p<0.05). These data indicate that dysregulation of mRNAs, lncRNAs, and circRNAs may contribute to breast cancer progression.

SAGE-Seq gene expression profiles of Hs578T, MCF7, and SUM159PT cells treated with STAT3 or non-targeting siRNAs, DMSO, or CXCR2, PTGIS, HAS1, PFKFB3, JAK, or NQO1 inhibitor

Project description:To investigate potential links between Stat3 transcriptional activity and other signaling pathways in breast cancer, we determined the gene expression profiles of three breast cancer cell lines treated with JAK, PTGIS, PFKFB3, CXCR2, HAS1, or NQO1 inhibitor (all of which decreased Stat3 transcriptional activity in Hs 578T cells except for the NQO1 inhibitor), inhibitor treatment vehicle alone (DMSO), STAT3 siRNAs, or non-targeting siRNAs. Using the resulting data, we identified a gene signature that was significantly regulated by STAT3 siRNAs and similarly affected by the JAK and at least 3 other inhibitors (or by 4 other inhibitors) but not by the NQO1 inhibitor in Hs 578T cells that was enriched in genes involved in development and correlated with shorter distant metastasis-free survival in primary lymph-node-negative invasive breast tumors. These results emphasize the central importance of Stat3 in CD44+/CD24- stem-cell-like breast cancer cells.
