Description
By comparing Sirt6-silenced YAMC cells to siControl-transfected YAMC cells, we found that there were 916 and 1,026 differentially expressed genes in the naïve and TNF-a treatment conditions respectively. We also found that there were 302 genes that were co-expressed differentially in both naïve and TNF-a treatment conditions between Sirt6-silenced and siControl-transfected YAMC cells. Overall design: YAMC cells were transfected with Sirt6 siRNA (siSirt6, 50 nM) and negative control siRNA (siControl, 50 nM) respectively using lipofectamine 2000. Forty-eight hours after transfections, the cells were cultured with medium containing TNFa (100 ng/mL) and medium alone respectively for additional 24 h. At the end of treatments, cells were harvested for RNA extraction followed by RNA-seq transcriptome analysis.

Description
The current understanding of the molecular factors underlying LF2000-mediated transfection is largely unknown. Cationic LF2000 gene delivery system was used to transfer GFP transgene to HEK293T cells. FACS separation of transfected (GFP positive), untransfected (GFP negative), and untreated cells enabled gene expression profiles to be obtained using Affymetrix HG-U133A 2.0 microarrays for each cell population. Gene profiles were differentially compared for each population combination.

Description
Wnt signaling is intrinsic to mouse embryonic stem cell self-renewal. Therefore it is surprising that reprogramming of somatic cells to induced pluripotent stem cells (iPSCs) is not strongly enhanced by Wnt signaling. Here, we demonstrate that active Wnt signaling inhibits the early stage of reprogramming to iPSCs, while it is required and even stimulating during the late stage. Mechanistically, this biphasic effect of Wnt signaling is accompanied by a change in the requirement of all four of its transcriptional effectors: Tcf1, Lef1, Tcf3, and Tcf4. For example, Tcf3 and Tcf4 are stimulatory early but inhibitory late in the reprogramming process. Accordingly, ectopic expression of Tcf3 early in reprogramming combined with its loss-of-function late enables efficient reprogramming in the absence of ectopic Sox2. Together, our data indicate that the step-wise process of reprogramming to iPSCs is critically dependent on the stage-specific control and action of all four Tcfs and Wnt signaling.

Description
Argonautes, a family of highly evolutionarily conserved proteins, are the central platform for small RNA-mediated gene regulatory mechanisms which occur mainly in the cytoplasm. To understand a potential role of Argonaute 1 (Ago1) protein in the nucleus of mammalian cells in regulating gene transcription and epigenetics, we performed integrated analyses of Ago1 ChIP-sequencing (GSE40536) and gene expression profiling in cells depleted of Ago1. For gene expression profiling, we knocked down the expression of Ago1 by siRNA in PC-3 cells and compared gene expression profiles in the cells depleted of Ago1 and cells receiving control treatments. We found that Ago1 depletion resulted in more downregulated genes which were enriched in gene responsible for promoting cell cycle progression, DNA replication and repair, and response to endogenous stimuli. Integrated analyses of Ago1-chromosomal interactions and gene expression changes in response to Ago1 depletion reveal a significant correlation between Ago1-bound genes and genes altered by Ago1 depletion. These genes are significantly enriched in cancer-related pathways. Our data suggests a nuclear function of Ago1 in regulating gene transcription.
