Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Transcriptional profiling of human acute myelogenous leukemia (AML) CD34+ cells treated with 5 M fenretinide. Two timepoints included are 6h, 12h, covering the apoptosis-induction time window of AML CD34+ cells responsing to the fenretinide treatment. We studied gene expression series in human AML CD34+ cells with or without 5 M fenretinide treatment by cDNA microarray analysis. Several signal transduction pathways are involve, including stress response, NF-kappaB inhibition and p53 inhibition (p<0.05). These findings indicate fenretinide may represent a promising candidate for targeting AML-initiating cells.

Description
The mechanistic target of rapamycin complex 1 (mTORC1) regulates beta cell growth and mass; yet it remains unclear whether it also directs beta cell functional maturation. To understand the global molecular basis of the phenotype caused by the loss of Raptor in beta cells, we isolated pancreatic islets from 8-week-old RapKO and WT mice. We compared gene-expression profile by Affymetrix microarray of islets, which revealed that a number of mRNAs were dys-regulated in Raptor-deficient islets.

Description
PML-RARa contributes to the development of APL through repression of genes important in myeloid development. Through a global approach, we have identified 2,979 high quality PML-RARa binding sites in ZnSO4 induced PR9 cells. By integration the gene expression data, we found that PML/RARa target genes are transcriptionally suppressed in primary APL cells and re-activated in ATRA treated NB4 cells.

Description
NB4 is an APL derived cell line, carrying the t(15;17) translocation and expressing the PML/RARa fusion protein. Still, an important question that remains to be addressed is whether PML/RARa target genes are transcriptionally suppressed in primary APL cells and re-activated in all-trans retinoic acid (ATRA) treated NB4 cells. Gene expression of NB4 cells treated with ATRA at different time points were analyzed.

Description
Developmental Origins of Health and Disease Hypothesis (DOHaD) all emphasized that maternal nutrition plays an important role on the growth and development of offspring. More and more attention has been paid on the effect of maternal high fat diet and overnutrition during pregnancy on the susceptibility of offspring metabolic diseases. So we aim to build the rat model of maternal high fat diet which may induce steatohepatitis and change of lipid metabolism in the early life of offspring, and explore their possible mechannisms.And then to investigate the influence of maternal high fat diet on the expression of hepatic metabolic genes in the early life of offspring.

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.
