View SamplesUsing microarray, the anther transcript profiles of the three indica rice CMS lines revealed 622 differentially expression genes (DEGs) in each of the three CMS lines. GO and Mapman analysis indicated that these DEGs were mainly involved in lipid metabolic and cell wall organization. Comprised with the gene expression of sporophytic and gametophytic CMS lines, 303 DEGs were differentially expressed and 56 of them were down-regulated in all the CMS lines. Co-expression network analysis suggested that many genes were significantly differentially expressed in the CMS lines. These down-regulated DEGs in the CMS lines were found to be involved in tapetum or cell wall formation and their suppressed expression might be related to male sterility. The present study will give some information for the nuclear gene regulation by different cytoplasmic genotypes and provide some candidate genes for pollen development in rice.

View SamplesWe found that IL-7 pretreatment enhanced Th9 differentiation. To clarify the underlying mechanisms, we examine the gene expression profiles of CD4+ T cell and Th9 cells with or without IL-7 pretreatment. In Th9 cells, we found that Th9 related genes were greatly increased in IL-7 Th9 group, which demonstrated an enhanced Th9 differentiation. In CD4+ T cells, we found that IL-7 treatment resulted in a global gene expression change especially on chromatin remodeling related genes, which facilitated the entry of transcriptional factor to the Il9 promoter region and promoted Il9 transcription.

View SamplesHep3B and Huh7 are two types of human hepatoma cell lines (HCC). In our laboratory, we cultured their stem-like cancer cells (HCSCs), Hep3B-C and Huh7-C. And we have demonstrated that these cells had enhanced stem cell properties, drug resistance, properties of EMT, and stronger tumor-initiating capabilities. To explore functionally crucial mRNAs in HCSCs, 2 samples of HCSCs and 2 samples of HCCs were sequenced by the Illumina Genome Analyzer II. Through differential expression analysis, we finally identified 115 up- and 402 down-regulated miRNAs which were consistently up- and down-regulated in two stem cells compared to the cancer cells. Overall design: Expression analysis using total RNAs extracted from 2 HCSC cell lines (Hep3B-C and Huh7-C), and 2 HCC cell lines (Hep3B and Huh7).

View Sampleswe have investigated molecular and functional properties in early B-lineage cells from Pax-5 deficient animals crossed to a B-lineage restricted reporter mouse. Gene expression analysis of ex vivo isolated progenitor cells revealed that Pax-5 deficiency has a minor impact on Bcell specification.By comparison of gene expression patterns in ex vivo isolated Pax-5 and Ebf-1 deficient progenitors, it was possible to identify a set of B-cell restricted genes dependent of Ebf-1 but not Pax-5, supporting the idea that B-cell specification and commitment is controlled by distinct regulatory networks.
Single-cell analysis of early B-lymphocyte development suggests independent regulation of lineage specification and commitment in vivo.

View SamplesTumor formation constitutes a major obstacle to the clinical application of embryonic stem cells (ESCs). As P-RPCs could successfully integrate into host eyes without development of teratomas or NOG, we sought to identify differentially expressed genes between P-RPCs and ESC-RPCs through genome-wide transcript profiling. Inhibition of Wnt signaling by DKK1 promotes the commitment of ESC-RPCs to more mature retinal cells and reduces the occurrence of NOG to 3%. DKK1-treated ESC-RPCs efficiently integrate to the host retina, form synaptic connections and restore visual function.
WNT signaling determines tumorigenicity and function of ESC-derived retinal progenitors.

View SamplesIn vertebrates, non-lens bg-crystallins are widely expressed in various tissues, but their functions are unknown. The molecular mechanisms of trefoil factors, initiators of mucosal healing and being greatly involved in tumorigenesis, have remained elusive.A naturally existing 72-kDa complex of non-lens bg-crystallin (a-subunit) and trefoil factor (b-subunit), named bg-CAT, was identified from frog Bombina maxima skin secretions. Its a-subunit and b-subunit (containing three trefoil factor domains), with a non-covalently linked form of ab2, show significant sequence homology to ep37 proteins, a group of non-lens bg-crystallins identified in newt Cynops pyrrhogaster and mammalian trefoil factors, respectively. The bg-CAT showed multiple cellular effects on human umbilical vein endothelial cells. Low dosages of bg-CAT (25-50 pM) were able to stimulate cell migration and wound healing. At high concentrations, it induced cell detachment (EC50 10 nM) and apoptosis. The bg-CAT was rapidly endocytosed via intracellular vacuole formation. Under confocal microscope, some of the vacuoles were translocated to nucleus and partially fused with nuclear membrane. However, what exactly target of bg-CAT act on HUVECs nuclear is still unknown. Primary cultured HUVECs treated with bg-CAT (25 nM, 2 h) were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genome wide level of significant differential gene expression induced by bg-CAT on HUVECs in order to get clues about bg-CAT action mechanisms. These findings illustrate novel cellular functions of non-lens bg-cyrstallins and action mechanism via association with trefoil factors, serving as clues for investigating the possible occurrence of similar molecules and action mechanisms in mammals.
