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
Background: Colorectal cancers are believed to arise predominantly from adenomas. Although these precancerous lesions have been subjected to extensive clinical, pathological, and molecular analyses, little is currently known about the global gene expression changes accompanying their formation. Results: To characterize the molecular processes underlying the transformation of normal colonic epithelium, we compared the transcriptomes of 32 prospectively collected adenomas with those of normal mucosa from the same individuals. Important differences emerged not only between the expression profiles of normal and adenomatous tissues, but also between those of small and large adenomas. A key feature of the transformation process was the remodeling of the Wnt pathway reflected in patent over- and underexpression of 78 known components of this signaling cascade. Conclusions: Our transcriptomic profiles of normal colonic mucosa and colorectal adenomas shed new light on the early stages of colorectal tumorigenesis.

Description
Huntingtons disease (HD) is a dominantly inherited genetic disease caused by mutant huntingtin (htt) protein with expanded polyglutamine tracts. A neuropathological hallmark of HD is the presence of neuronal inclusions of mutant htt. p62 is an important regulatory protein in selective autophagy, a process by which aggregated proteins are degraded, and it is associated with several neurodegenerative disorders including HD. Here we investigated the effect of p62 depletion in three HD model mice: R6/2, HD190QG and HD120QG mice. We found that loss of p62 in these models led to longer lifespans and reduced nuclear inclusions, although cytoplasmic inclusions increased with polyglutamine length. In mouse embryonic fibroblasts (MEFs) with or without p62, mutant htt with a nuclear localization signal (NLS) showed no difference in nuclear inclusion between the two MEF types. In the case of mutant htt without NLS, however, p62 depletion increased cytoplasmic inclusions. Furthermore, to examine the effect of impaired autophagy in HD model mice, we crossed R6/2 mice with Atg5 conditional knockout mice. These mice also showed decreased nuclear inclusions and increased cytoplasmic inclusions, similar to HD mice lacking p62. These data suggest that the genetic ablation of p62 in HD model mice enhances cytoplasmic inclusion formation by interrupting autophagic clearance of polyQ inclusions. This reduces polyQ nuclear influx and paradoxically ameliorates disease phenotypes by decreasing toxic nuclear inclusions.

Description
Germinal center (GC) B cells cycle between two states, the light zone (LZ) and the dark zone (DZ), and in the latter they proliferate and hypermutate their immunoglobulin genes. How this functional transition takes place is still controversial. In this study, we demonstrate that ablation of Foxo1 after GC development led to the loss of the DZ GC B cells and disruption of the GC architecture. Mechanistically, even upon provision of adequate T cell help, Foxo1-deficient GC B cells showed less proliferative expansion than controls. Moreover, we found that the transcription factor BATF was transiently induced in LZ GC B cells in a Foxo1-dependent manner and that deletion of BATF similarly led to GC disruption. Thus, our results are consistent with a model where the switch from the LZ to the DZ is triggered after receipt of T cell help, and suggest that Foxo1-mediated BATF up-regulation is at least partly involved in this switch. Overall design: mRNA profiles of wild-type DZ, LZ, and Foxo1-deficient GC B cells were generated by deep sequencing in triplicate, using Illumina HiSeq 1500.

Description
Decoy receptor 3 (DcR3), a member of the tumor necrosis factor receptor (TNFR) superfamily, competitively binds and inhibits members of the TNF family, including Fas ligand (FasL), LIGHT, and TL1A. DcR3 was recently reported not only to act as a decoy receptor for these TNFRs but also to play a role as a ligand for the pathogenesis of RA.

Description
Global gene expression profiling of the avian B-lymphoma DT40 cell line was used as a model to differentiate among Btk KO and Btk KO cells reconstituted with human Btk. Differences in the gene expression pattern showed statistically significant changes between parental DT40 and all the Btk KO cell populations irrespective of whether they are reconstituted or not. These results imply that in the process of generating a knockout cell line, subclones are selected, which have multiple changes in their gene expression pattern (p<0.01).

Description
Overall goal: To identify genes that will cause non-fusogenic fibroblasts to become fusogenic. Purpose of analysis: To generate transcriptional profile of non-fusogenic fibroblasts, using 10T1/2 fibroblasts transduced with empty retrovirus as model. Experimental structure: The profile generated from the RNAseq analysis would be compared with transcriptional profile of MyoD-expressing fibroblasts (GEO DataSet GSE34907) to identify genes regulating fusion in muscle cells. Overall design: RNAseq analysis of total RNA from 10T1/2 fibroblasts transduced with retrovirus carrying empty pBabe-X retroviral vector was carried out to generate a transcriptional profile of a model of non-fusogenic fibroblasts.
