FRY Impacts Breast Cancer Malignancy by Inducing an Enrichment of Genes with Tumor-Suppressive Functions and Affecting EMT Potential of Breast Cancer Cells

Project description:Breast cancer is a disease with diverse phenotypes, and while the progression of breast cancer from a localized lesion to metastatic disease is well understood clinically. Our previous study genetically linked the FRY gene with differential susceptibility to mammary carcinogenesis; however, little is known about the mechanistic insights of FRY in mammalian cells and breast cancer progression. Through RNA-Seq analysis of series of constructed cell lines based on highly malignant triple-negative human breast cancer cells MDA-MB-231, we show that enhanced FRY induces massive changes in gene expression, which favor signalings and molecules with tumor-suppressive functions and engage in promoting cell differentiation, maintaining the normal and histopathological characteristics of epithelial cells, and in regulating EMT potential of breast cancer cells. As a result, the proliferation, migration and invasion potentials of breast cancer cells are significantly inhibited both in vitro and in xenograft tumor models. Importantly, consistent with FRY’s anti-tumor progression role, decreased FRY protein levels are correlated with poorly differentiated and aggressive tumor phenotypes in the analysis of two clinically annotated breast cancer cohorts. Our results identify FRY’s potent tumor-suppressive role at the gene transcription and molecular function levels, providing a novel biomarker for breast cancer prognosis and a target for therapeutic intervention.

Expression of FRY-targeting shRNA in MCF10A cells

Project description:We identified the predicted FRY gene as a candidate mammary carcinoma susceptibility gene. This gene has not been characterized in mammals, so for part of our analysis we conducted microarray experiments to look at the changes in gene expression which occur when FRY-targeting shRNA is expressed in the nontumorigenic MCF10A mammary epithelial cell line (a cell line which we identified as having higher FRY mRNA expression than breast cancer cell lines). We used microarrays to identify the FRY interactome and identified that FRY affects the expression of gene networks that maintain normal cellular and tissue architecture, organization, differentiation of epithelial cells.

Ectopic expression of wild-type Cop Fry in MDA-MB-231 cells

Project description:We identified the wt Cop allele of the predicted Fry gene as a mammary carcinoma susceptibility gene. This gene has not been characterized in mammals, so for part of our analysis we conducted microarray experiments to look at the changes in gene expression which occur when the wt Cop Fry allele is ectopically expressed in the MDA-MB-231 breast cancer cell line (a cell line which we identified as having low FRY mRNA expression). We used microarrays to identify the Fry interactome and identified that Fry affects the expression of gene networks that maintain normal cellular and tissue architecture, organization, differentiation of epithelial cells.

Proliferative genes dominate malignancy-risk gene signature in histologically-normal breast tissue

Project description:Analysis of 143 completely histologically-normal breast tissues resulted in the identification of a “malignancy risk” gene signature that may serve as a marker of subsequent risk of breast cancer development. Keywords: Tissue from breast cancer and adjacent regions

The UPR Transducer IRE1 Promotes Breast Cancer Malignancy by Degrading Tumor Suppressor microRNAs

Project description:To understand the mechanistic basis by which inositol-requiring enzyme 1 (IRE1) is involved in luminal breast cancer malignancy, we analyzed the transcriptomic signature that IRE1 regulates in breast cancer. We suppressed the activity of IRE1 RNase in luminal breast cancer SUM52 line by adenoviral-based over-expression of the IRE1 dominant-negative K599A or K907A, and then performed RNA-sequencing (RNA-seq) analysis with IRE1 dominant-negative and control SUM52 cells. Through the RNA-seq analysis, we identified 98 genes that were commonly upregulated (65 genes) or downregulated (33 genes) in K599A-expressing SUM52 (SUM52-K599A) or K907A-expressing SUM52 (SUM52-K907A) cells.

Hypoxia-induced TET-TNFa-p38-MAPK signaling axis drives tumor malignancy of human breast cancer

Project description:Hypoxia, a hallmark of most solid tumors, leads to aberrations in epigenetic modifications promoting malignant tumor phenotypes, including metastatic features and stem cell-like characteristics. Aberrant DNA methylation has been considered to play an essential role during tumor progression and tightly associate with tumor malignancy. However, the mechanism by which hypoxia alters DNA methylation to promote tumor malignancy remains poorly understood. Ten-eleven translocation 1-3 (TET1-3) proteins, which catalyze the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), play a critical role in the DNA demethylation that controls different biological processes. Here we demonstrate that the expression of TET1 and TET3 is closely associated with tumor hypoxia, tumor malignancy and poor prognosis of patients with breast cancer. Hypoxia results in deregulation of TET1 and TET3, leading to breast tumor initiating cell (BTIC) properties. Mechanically, hypoxia regulates expression of TET1 and TET3 via hypoxia-inducible factor-1a (HIF-1a), thereby resulting in 5hmC genome-wide changes, which in turn leads to the upregulation of TNFa expression and activation of its downstream p38-MAPK pathway. Importantly, signal transduction through the TET-TNFa-p38-MAPK signaling axis is required for the acquisition of BTIC characteristics and chemotherapy resistance, leading to more malignant tumor phenotypes. Inhibition of the hypoxia-TET-TNFα-p38-MAPK signaling pathway results in compromised BTIC properties and tumorigenicity in vitro and in vivo, suggesting a possible therapeutic strategy.
