Expression data comparing Huh7 CD133+ and CD133- HCC cells
ABSTRACT: To identify candidate genes involved in enhanced tumorigenicity of CD133+ liver tumor-initiating cells Affymetrix Human Genome U133 Plus GeneChip 2.0 HCC cell line Huh7 was sorted into CD133+ and CD133- populations by flow cytometry
<h4>Unlabelled</h4>A novel theory in the field of tumor biology postulates that cancer growth is driven by a population of stem-like cells, called tumor-initiating cells (TICs). We previously identified a TIC population derived from hepatocellular carcinoma (HCC) that is characterized by membrane expression of CD133. Here, we describe a novel mechanism by which these cells mediate tumor growth and angiogenesis by systematic comparison of the gene expression profiles between sorted CD133 liver su ...[more]
Project description:To identify candidate genes involved in enhanced tumorigenicity of CD133+ liver tumor-initiating cells Affymetrix Human Genome U133 Plus GeneChip 2.0 HCC cell line PLC8024 was sorted into CD133+ and CD133- populations by flow cytometry
Project description:To identify candidate genes involved in enhanced tumorigenicity and metastasis of CD90+ esophageal tumor-initiating cells. The esophageal squamous carcinoma cell (ESCC) cell line KYSE-140 was sorted into CD90+ and CD90- populations by flow cytometry. Total RNA was analyzed on Affymetrix Human Genome U133 Plus GeneChip 2.0 arrays.
Project description:To identify candidate genes that are up-regulated in chemoresistant (cisplatin and doxorubicin) hepatospheres as compared with their differentiated counterparts Affymetrix Human Genome U133 Plus GeneChip 2.0 PLC/PRF/5 HCC cells were grown as spheroids and treated with cisplatin and doxorubicin combination. Differentiated counterparts were generated by addition of FBS in the spheroids and allowed to attach.
Project description:To identify CD24 signaling pathway Affymetrix Human Genome U133 Plus GeneChip 2.0 shRNA CD24 (knockdown) or non-target control (NTC) was stably transduced into Huh7 HCC cells by lentiviral approach
Project description:Expression from CD133+ cells isolated from adult human exocrine tissue was compared to a CD133-depleted cell population Islet-depleted exocrine tissue from three independent adult human cadaveric pancreata were cultured for four days in Miami media 1A. Following trypsinization, cells were isolated using anti-CD133 immunomagnetic beads to >95% CD133+. CD133-negative cells were further depleted of CD133+ cells to <1% CD133+.
Project description:CD133 has been widely used for identification and isolation of cancer stem cells in tumors although its role as a marker for cancer stem cell is still controversial . We isolated the CD133+ and CD133- cells from SW620 human colon cancer cell line and compared their biological characteristics, such as tumorigenicity,drug sensitivity, etc. Our study revealed that CD133+ SW620 cells were more tumorigenic and resistant to anti-cancer drugs. Correspondingly, they displayed different gene expression profile. However, it was observed that CD133- cells and CD133+ cells could mutually convert, indicating that CD133 expression was under dynamic and reversible regulations which might impose significant infulence on cells behaviors. Thus, our data challenge the role of CD133 as a marker for cancer stem cell. There are two populations with distinct expression of CD133 in SW620 human colon cancer cell line. Microarray assays were employed to investigate the differentially expressed genes between the two populations, which may possess different tumorigenetic potential and sensitivity to anti-cancer drugs. CD133+ and CD133- cells were isolated from human colon cancer SW620 cell line by magnetic cell sorting system. The clones from sorted CD133+ or CD133- populations were established. Clone cells were expanded and were further purified by using CD133 cell isolation kit before microarray assays.
Project description:To identify regulators of human HSC fate, we transcriptionally profiled quiescent primitive cord blood (CB) CD133+ G0 cells enriched for long term culture initiating cell (LTC-IC) activity. CD133+ G0 cells were sorted by cell cycle status using combined DNA and RNA staining; less immature CD133+G1 cells served as a comparison.
