Overexpression of miR-200s in murine ovarian cancer cells (ID8 and 28-2)

ABSTRACT: Little is known about the role of miR-200s in the progression of ovarian cancer. In this study we overexpressed the miR-200c/141 cluster, the miR-200b/200a/429 cluster, or both clusters in two different murine ovarian cancer cell lines (ID8 and 28-2). As co-oeverexpression of both clusters provided the best miR-200 overexpression, we evaluated ID8 and 28-2 cells overexpressing both miR-200 clusters (ID8-200f and 28-2-200f) compared to empty vector control cells (ID8EV and 28-2EV). ID8-200f and 28-2-200f cells showed increased expression of several mesenchymal genes, decreased proliferation, decreased invasion and increased apoptosis compared to their respective controls. RNA sequencing of ID8EV, ID8-200f, 28-2EV and 28-2-200f cells revealed that overexpression of miR-200s primary regulated genes involved in epithelial mesenchymal transition EMT) and gene implicated in migration. Therefore, our work suggests that miR-200s can inhibit characteristics associated ovarian cancer progression (increased proliferation and invasion and promotion of EMT).

Expression data from ovarian cells growing in three dimensional culture (Matrigel) with altered expression of miR-200s

Project description:It is believed that incessant ovulation will cause formation of ovarian cysts which later lead to ovarian cancer maglinancy. miR-200s is highly expressed in ovarian cancer tissue when compared to ovarian normal tissue. To study wether miR-200s have a pathologenic role in ovarian cyst formation, normal ovarian cells with overexpression of miR-200s and two cancer cell lines with knockdown of miR-200s were grown in a 3D culture system and allowed to form cyst. We used microarrays to detail the global programme of gene expression underlying ovarian cyst formation affected by expression of miR-200s and indentify distinct classes of up-regulated and down-regulated genes during this process.

In vivo-selected ID8 ovarian cancer cells display accelerated peritoneal metastasis accompanied with increased macrophage recruitment and M2 polarization

Project description:Ovarian cancer is the leading cause of gynecological cancer related death. The overall 5 year survival rate is only 29%. Over 85% of ovarian cancer patients present with advanced stage III or IV disease characterized by intraperitoneal metastasis when diagnosed. However, the process and mechanism of ovarian tumor metastasis remain poorly understood partially because of the lack of a mouse model which could recapitulate the development of metastatic lesion in an appropriate timeframe. In order to generate a convenient ovarian cancer model with accelerated peritoneal metastasis, we performed an in vivo selection study using ID8 ovarian cancer cells to establish a rapid metastasizing mouse ovarian cancer cell line, designated ID8-M. Syngeneic mice with intraperitoneal inoculation of ID8-M cells showed measurable ascites average 35 days after the inoculation and survived only an average of 52 days, while those inoculated with parental ID8 cells showed measurable ascites after 67 days and survived over 81 days. Further analysis showed that, compared with ID8 tumors, ID8-M tumors resulted in more macrophages in the ascites; and compared to ID8 cells, ID8-M cells were more potent to promote macrophages to acquire a M2 phenotype. A microarray analysis provided information to explain the accelerated metastatic phenotype of ID8-M cells.

Genetically modified ID8 cells to study the role of GBP1 in ovarian cancer

Project description:Genetically modified ovarian cancer cells were used to study the role of GBP1. Proteomics-based thermal stability assay (CETSA) was performed on GBP1 knockdown and overexpressing ID8 ovarian cancer cells. Shotgun proteomics was also performed on these cells.

Investigation of the direct activity of interferon epsilon on ID8 ovarian cancer cells in vitro.

Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The objective of this experiment was to examine the direct activity of interferon epsilon on the mouse ovarian cancer cell line, ID8, and compare it to equivalent unit concentrations of interferon beta. The goal was to determine whether interferon epsilon and interferon beta induce different patterns of gene expression in ID8 cells.

Global changes in gene expression in response to miR-200 overexpression in 4TO7 cells

Project description:Transcriptional profiling of 4TO7 cells stably overexpressing miR-200s or CDH1. We observe a dramatic shift in the gene signatures when miR-200s (cluster 2; miR-200c/141, or both clusters) are overexpressed relative to controls. However, cluster 1 overexpression (miRs-200b/a/429) alone or CDH1 overexpression does not induce global changes in gene expression to levels observed for cluster 2 (miR-200c/141) or both clusters together. One cell line (4TO7) cells: four different overexpression experiments, Cluster 1, Cluster 2, Clusters 1+2, CDH1, and respective controls, Puro vec, Hygro vec, Puro+Hygro vec and Puro vec. Each experiment has two biological replicates. Total, 16 samples.

TGFb treated EpRAS cells undergoing hysteretic vs non-hysteretic EMT gene expression analysis.

Project description:EpRAS cells undergo EMT transition through hysteresis showing bistability of the system. The hysteresis transition is controlled by the negative feedback loop between miR-200s and Zeb1. Disruption of the feedback loop through the deletion of Z-box2 in the miR-200s cluster-2 promoter region changes the transition to unimodal without hysteresis. To determine the consequence of cells undergoing through hysteresis or unimodal transitions of EMT, herein we determined the transcriptomic profiles of EpRAS wild type and EpRAS-delZbox2 mutant cells, (designated as EpRAS-C2-2). To induce EMT, the cells were treated with 100pM TGFbeta for 3 days. Mock PBS treatment is used as control.

Investigation of the direct activity of type I interferon on Ifnar1 KO ID8 ovarian cancer cells in vitro.

Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The goal of this experiment was to assess whether interferon signalling had been ablated in Ifnar1 CRISPR knockout (KO) ID8 cell lines, so that they could be used for in vivo models of ovarian cancer.
