Transcriptome profiling of SW480 cells and cells derived from xenograft tumors from serial transplantation of SW480 cells by RNA-sequencing

ABSTRACT: SW480 is a colorectal cancer cell line. We have shown that cancer cells are characteristic of neural stem cells and neural stemness contributes to cell tumorigenicity. We found that during serial transplantation of SW480 cells into nude mice via subcutaneous injection (in vivo passaging), the cells enhanced their neural stemness, tumorigenicity and pluripotent differentiation potential.
Project description:We have showed that cancer cells (or tumorigenic cells) resemble neural stem/progenitor cells in regulatory network, tumorigenicity and differentiation potential. We have shown PRMT1 is a protein that is upreguated in and promotes vaious cancers. The expression of its gene is localized to embryonic neural cells during vertebrate embryogenesis. The project is to identify the interaction partners of PRMT1, by which PRMT1 regulates neural stemness in both cancer cells and neural stem cells.

Project description:Heparanase (HPSE), the only known mammalian endoglycosidase responsible for heparan sulfate cleavage, is a multi-faceted protein affecting multiple malignant behaviors in cancer cells. The goals of this study are to compare the mRNA transcriptome differences between SW480 cells and HPSE-knockdown SW480 cells. Methods: mRNA profiles of SW480 cells and HPSE-knockdown SW480 cells were generated by deep sequencing, in triplicate, using Illumina.
Project description:ChIP-on-chip tilling array comparing untreated human SW480 cells vs SW480 cells treated with 2mM H2O2 for 30min. Exposing cells to the reactive oxygen species, hydrogen peroxide, recruits DNA methyltransferase 1 (DNMT1) to damaged chromatin. DNMT1 becomes part of a complex(es) containing DNMT3B and members of Polycomb Repressive Complex 4. The goal was to determine the effect of hydrogen peroxide treatment on chromatin, including changes in histone modifications and binding patterns of chromatin-associated proteins.

[Agilent-014707]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and EZH2. [Agilent-026595]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and H3. [Agilent-027811]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Four-mark: H3, 3MeK4H3, AcK16H4, and 3MeK27H3.
Project description:We have previously reported that colon cancer stem-like cells can be induced from human colon cancer cell lines by retrovirally introducing OCT3/4, SOX2 and KLF4, and we designated these cells as induced cancer stem cells (iCSCs). iCSCs showed significantly enhanced CSC properties in terms of the marker gene expression, sphere formation, chemoresistance and tumorigenicity. In the current study, we generated iCSCs using a polycistronic retroviral expression vector, and indicated that iCSCs-derived tissues in vitro are able to recapitulate human colon cancer tissues. To identify the molecular mechanisms that promote the properties of CSCs, we compared the global gene expression patterns of Mock-SW480 cells, non-V50 cells from 1st V50-OKS cells, and 2nd V50-OKS cells.
Project description:To investigate the cooperative function ALDH1B1 in the regulation of colon cancer cells, we established SW480 cell lines in which ALDH1B1 has been knocked down by shRNA and the control SCR SW480 cells.
