Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Trophoblast lineages, as the precursor of placenta, are essential for post-implantation embryo survival. However, the regulatory networks for trophoblast development remains incompletely understood. Here, we identified CITED1 as a regulator to induce trophoblast-like differentiation from mESCs. Overexpression of CITED1 in ESCs prompted differentiation towards trophoblast accompanying with elevated expression of trophoblast marker genes. To evaluate the ability of CITED1 to induce trophoblast differentiation at a genome-wide scale, we compared the global transcriptional profiles between CITED1 overexpressing cells and control ESCs by Affymetrix microarray analysis at day 1 and day 2 after transfection.

Description
Platinum-based compounds exert their anti-neoplastic effect through direct binding to DNA, which blocks fundamental cellular process ultimately resulting in apoptotic cell death. However, many ovarian cancers become refractory to treatment with platinum-based compounds. To improve the existing therapies for ovarian cancer, we sought to identify potent, nontoxic and specific drug candidates that have anti-neoplastic effects towards cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. Using a cell-based screening assay, we evaluated 56 compounds-derived from the Chinese medicinal plant, Phytolaccae, and one phytoaccagenin compound (Hu-17) was selected on the basis of its ability to dramatically decrease the viability of cisplatin-resistant SK-OV-3 cells.Using high-throughtput microarray system, we identified GO terms and pathway signatures enriched in Hu-17 and/or cisplatin treated SK-OV-3 cells.

Description
Degenerative retinal diseases like age-related macular degeneration (AMD) are the leading cause of blindness. Cell transplantation showed promising therapeutic effect for such diseases, and retinal progenitor cell (RPC) derived from embryonic stem cell (ESC) is one of the sources of such donor cells. Here, we established two protocols through which two types of rat ESC-derived RPCs (rESC-RPCs) were obtained and both contained some NPCs and committed retina lineage cells. As P-RPCs have been reported to successfully integrate into host eyes, we sough to identify differentially expressed genes among P-RPCs, rESC-RPC1s and rESC-RPC2s through genome-wide transcript profiling. rESC-RPC2 can integrate into the host retina, form synaptic connections and restore visual function after transplanted into the degenerative retinal disease model RCS rat.

Description
Fenretinide has shown its antitumor activity in many tumor types with low cytotoxicity to normal cells. Recently, we have shown that fenretinide could eradicate chronic myeloid leukemia stem/progenitor cells and spheres from ovarian cancer. In this study, we investigate whether fenretinide could selectively target sphere cells of colon cancer. Using high-throughtput microarray system, we identified GO terms and pathway signatures enriched in fenretinide treated HT29 cells and HT29 derived sphere cells.

Description
The protein level of OCT4, a core pluripotency transcriptional factor, is vital for embryonic stem cell (ESC) maintenance, differentiation and somatic cell reprogramming. Although OCT4 protein is regulated at multiple scales, the role and regulatory mechanisms of OCT4 ubiquitination in reprogramming remains elusive. We identified the five lysine residues as ubiquitination sites on OCT4, and found that destruction of the ubiquitination can enhance OCT4 activity in reprogramming.

Description
Residence of cancer-propagating cells (CPCs) within preferential microenvironmental niches has a major part in evading therapy. However, the nature of niches involved and the mechanisms protecting CPCs remain largely unknown. We addressed these issues in mouse transplantation models of acute lymphoblastic leukemia (ALL). When the engrafted leukemic cells substantially damaged adjacent vascular structures and endosteal linings in the bone marrow (BM), after chemotherapy small foci of CPCs were retained, surrounded by sheaths of supporting cells that comprise a novel niche. We investigated patients BM biopsies and found evidence of a similar process in patients receiving induction-therapy. The efficacy of chemotherapy was enhanced by interfering with the niche formation or niche-CPC interaction. We therefore identified a therapy-induced niche that protects CPCs.

Description
Unlimited self-renewal and developmental pluripotency are hallmarks of embryonic stem cells. Both properties are precisely controlled by the extrinsic signals and intrinsic factors and have been extensively investigated. However, factors capable of converting ES cells to extra-embryonic lineages have been poorly studied. Here we found that overexpression of Ssbp3 dramatically up-regulated trophoblast specific markers. Then we investigated the genome-wide transcriptional effect of ectopic Ssbp3 expression by comparing the whole genome expression profiles of Ssbp3-overexpressing cells with negative control cells using affymetrix microarray.Genetic analysis indicated that overexpression of Ssbp3 drives the trophoblast transcriptional program, induces the expression of early trophectoderm transcription factors such as Cdx2, Gata3 and Elf5, and activates MAPK and TGF- pathways, which are essential for trophoblast derivation.Our findings identify Ssbp3 as a novel regulator converting ES cells into extra-embryonic trophoblast.

Description
Induced pluripotent stem (iPS) cells were produced from reprogramming of somatic cells, and they are shown to possess pluripotent properties similar to embryonic stem (ES) cells. Here we used microarrays to detail the global expression pattern among the ES cells and iPS cells, as well as the original mouse embryo fibroblast (MEF), to identify important players involved in the reprogramming process.
