View SamplesBisphenol S and mono-ethylhexyl phthalate are widely used in the industry of making plastic, mailing envelopes, tickets, etc. Humans are exposed to these compounds by skin contact, inhalation, and food ingestions. However, the molecular mechanisms of these compounds' adverse effects are still unclear. We address the molecular and cellular mechanisms underlying Bisphenol S and mono-ethylhexyl phthalate effects on HeLa cells.

View SamplesWe developed transcriptome expression assisted non-directed proteome profiling (TEAnDPP) method to investigate host-pathogen interaction. Analysis of HCV replicon induced host-cell metabolism perturbation at gene expression level. Gene enrichment analysis on DEG revealed disulfide formation related genes were significantly enriched. Based on this observation, we addminitrated thiol reactive chemical probes to visualize reactive thiol profile in live cell, and observed unique reactivity profile. Using SILAC-based quantitative profiling method, we identified 26 proteins that are labeled by iodoacetamide probes. Among these proteins, we discovered t-plastin was upregulated in APC140 cells, and its knock-down experiment showed significant HCV replication inhibition effect. In short, TEAnDPP strategy demonstrated its usefulness in host-pathogen interaction study for HCV infection.

View SamplesThe Arabidopsis thaliana NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), acts as a key regulator of xylem vessel differentiation. In order to identify direct target genes of VND7, we performed global transcriptome analysis using Arabidopsis transgenic lines in which VND7 activity could be induced post-translationally. This analysis identified 63 putative direct target genes of VND7, which encode a broad range of proteins, such as transcription factors, IRREGULAR XYLEM proteins and proteolytic enzymes, known to be closely associated with xylem vessel formation. Recombinant VND7 protein binds to several promoter sequences present in candidate direct target genes: specifically, in the promoter of XYLEM CYSTEINE PEPTIDASE1, two distinct regions were demonstrated to be responsible for VND7 binding. We also found that expression of VND7 restores secondary cell wall formation in the fiber cells of inflorescence stems of nst1nst3 double mutants, as well as expression of NAC SECONDARY WALL THICKENING PROMOTING FACTOR3 (NST3, however, the vessel-type secondary wall deposition was observed only as a result of VND7 expression. These findings indicated that VND7 upregulates, directly and/or indirectly, many genes involved in a wide range of processes in xylem vessel differentiation, and that its target genes are partially different from those of NSTs.

View SamplesThe expression of four transcription factors (OCT3/4, SOX2, KLF4, and c-MYC) can reprogram mouse as well as human somatic cells to induced pluripotent stem (iPS) cells. Expression of the c-MYC, also known as an oncogene, might induce carcinogenesis and thus, iPS cells produced with the use of c-MYC transduction cannot be used for human therapeutic applications. Furthermore, reprogramming efficiency was significantly reduced in the absence of c-MYC transduction. Here, we generated iPS cells from mesenchymal stromal cells (MSCs) derived from human third molars (wisdom teeth) by retroviral transduction of OCT3/4, SOX2, and KLF4 without c-MYC. Interestingly, clonally expanded MSCs, named 10F-15, could be used for iPS cell generation with 100-fold higher efficiency compared to that of other clonally expanded MSCs and human dermal fibroblasts. These iPS cells resembled human embryonic stem (ES) cells in many aspects, including morphology, ES markers expression, global gene expression, epigenetic states, and the ability to differentiate into the three germ layers in vitro and in vivo. Because human third molars are discarded as clinical waste, our data indicate that MSCs isolated from human third molars are a valuable cell source for the generation of iPS cells.

View SamplesR1R2R3-Myb proteins represent an evolutionarily conserved class of Myb family proteins important for cell cycle regulation and differentiation in eukaryotic cells. In plants, this class of Myb proteins are believed to play important roles in cell cycle regulation through transcriptional regulation of G2/M phase-specific genes by binding to common cis-elements, called MSA elements. In Arabidopsis thaliana, MYB3R1 and MYB3R4 act as transcriptional activators and positively regulate cytokinesis by activating transcription of KNOLLE, which encodes a cytokinesis-specific syntaxin. Here, we show that the double mutation myb3r1 myb3r4 causes pleiotropic developmental defects, some of which are due to deficiency of KNOLLE whereas other are not, suggesting multiple target genes are involved. Consistently, microarray analysis of the double mutant revealed altered expression of many genes, among which G2/M-specific genes showed significant overrepresentation of the MSA motif and a strong tendency to be down-regulated by the double mutation. Our results demonstrate, on a genome-wide level, the importance of the MYB3R-MSA pathway for regulating G2/M-specific transcription. In addition, MYB3R1 and MYB3R4 may have diverse roles during plant development by regulating G2/M-specific genes with various functions, as well as genes possibly unrelated to the cell cycle.
