Identification of genes differentailly expressed in cancer stem-like cells of ovarian serous carcinoma and its clinical significance

ABSTRACT: We found gene expression profiling of spheroid-forming cell (cancer stem-like cell) by cDNA microarray and validated the genes as prognostic markers of ovarian serous carcinoma. Total RNA obtained from four different spheroid-forming cell (S3, S4, S5, and sample 7) compared to corresponding parent cancer cell (control3-1, C4, C5 and control7) by cDNA microarray.

Differentially expressed gene profiles according to physical status of human papillomavirus integration in cervical cancer

Project description:Integration of human papillomavirus (HPV) DNA into the host genome is a critical aetiological event in the progression from normal cervix to intraepithelial neoplasm, and finally to invasive cervical cancer. In this study, we want to know how HPV DNA physical status relates to treatment outcome for cervical carcinomas. Cervical cancer samples were compared with normal sample. And also, we divided 39 cervical cancer patients into four groups according to HPV DNA physical status and investigated differentially expressed gene profiles in these groups using Agilent two-color experiment.

The global gene expression pattern by YDR374C deletion

Project description:The Ydr374c is the only protein that has the YTH domain in Saccharomyces cerevisiae. The YTH domain was identified by comparing all known protein sequences with the YT521-B splicing factor, and it is found only in eukaryotes. Recently, it has been reported that the YTH domain conveys RNA-binding ability to a new class of proteins. However, the roles of most YTH family members lacking common sequence motifs outside the YTH domain are unknown. Therefore, to investigate the function of Ydr374c, microarray analysis was performed using the wild-type and YDR374C deletion strains. For the microarray analysis, wild-type and YDR374C deletion strains were cultured in SD medium and harvested at the mid-exponential phase (OD600=0.7), and total RNA was extracted.

Transcriptional regulation of Sox17 in HUVEC

Project description:We identified Sox17 as a novel angiogenic transcription factor in the context of tumor. Our data revealed that Sox17 promotes tumor angiogenesis and tumor vessel abnormality. We found that Sox17 is specifically expressed in tumor endothelial cells within tumors. Our study elucidates a novel transcriptional regulation for tumor angiogenesis Control HUVECs vs. Sox17 knockdown HUVECs. Biological replicates: 3 control replicates, 3 transfected replicates.

Gene alteration in A549 cells by disinfectant PHMG

Project description:Polyhexamethyl guanidine is widely used as a disinfectant in various places such as hospitals and restaurants. In order to examine of PHMG cytotoxicity in lung adenocarcinoma A549 cells we treated 5 ug/ml PHMG for 24 h. To investigate cytotoxicity of commonly used bactericidal reagent PHMG, A549 cells were treated 5 ug/ml PHMG for 24 h. After then purified the total RNA from treated and untreated cells using the Rneasy mini kit (Qiagen). The concentration and purity of the total RNA was measured and performed gene array.

Isolation and characterization of stem-like cells from a human ovarian cancer cell line

Project description:Increasing evidence supports the existence of a subpopulation of cancer cells capable of self-renewal and differentiation into diverse cell lineages. These cancer stem-like or cancer initiating cells (CICs) also demonstrate resistance to chemo- and radiotherapy and may function as a primary source of cancer recurrence. We report here on the isolation and in vitro propagation of multicellular ovarian cancer spheroids from a well-established ovarian cancer cell line (OVCAR-3). Cells forming these spheroids display self-renewal potential, the ability to produce differentiated progeny and increased expression of genes previously associated with CICs. The spheroid-derived cells (SDCs) also demonstrate higher invasiveness, migration potential and enhanced resistance to standard anticancer agents relative to progenitor OVCAR-3 cells. SDCs display up-regulation of genes associated with epithelial-to-mesenchymal transitions (EMT), anticancer drug resistance and/or decreased susceptibility to apoptosis, as well as, down-regulation of genes typically associated with the epithelial cell phenotype and pro-apoptotic genes. Dataset includes 3 replicate cultures of parental OVCAR-3 cells and 3 replicate cultures of stem cell-like spheroid-derived cells

Transient activation of the WNT pathway after disruption/remodeling of colorectal cancer cell clusters promotes a malignant phenotype

Project description:Cancer progression and wound healing share some characteristics. Most colorectal cancers are differentiated adenocarcinomas that maintain three-dimensional structures to some extent. Hence, disruption of the architecture can provoke remodeling similar to the remodeling of normal intestinal epithelium. We used our recently developed three-dimensional culture system to investigate the response of cancer cell spheroids to mechanical disruption. Specifically, we developed a protocol for homogenous disruption of the spheroids that maintained the cell-cell contacts. After disruption, 9 spheroids from 9 patient samples reformed within a few hours, and 2 showed accelerated spheroid growth. Stemness increased after spheroid disruption, as assessed by marker expression, spheroid forming capacity, radiation sensitivity, and tumorigenesis. The spheroid-forming capacity increased in 6 of 11 spheroids. The disruption signature, as determined by gene expression profiling, supported the incidence of remodeling and predicted the prognosis of the colorectal cancer patients. WNT and HER3 signaling was increased in the reformed spheroids, and suppression of these signaling pathways attenuated the increases in growth and stemness after disruption. Thus, disorganized architecture in patient tumors might reflect the processes of disruption and subsequent remodeling and represent a cause rather than simply a consequence of malignancy progression. Gene expression in cancer tissue-originated spheroids (CTOSs) was measured at pre, 6 hr, 24 hr, and 4 days after mechanical disruption. One experiment was performed at each time point.
