Description
Nuclear FTY720-P is a potent inhibitor of class I histone deacetylases (HDACs) that enhances histone acetylations and regulates expression of a restricted set of genes independently of its known effects on canonical signaling through sphingosine-1-phosphate (S1P) receptors. We found that FTY720 is phosphorylated in Era-negative breast cancer cells by nuclear sphingosine kinase 2 and accumulates these cells.
Publication Title
The phosphorylated prodrug FTY720 is a histone deacetylase inhibitor that reactivates ERα expression and enhances hormonal therapy for breast cancer.

Description
Background: Blau syndrome, or early-onset sarcoidosis, is a juvenile-onset systemic granulomatosis associated with a mutation in Nucleotide-binding oligomerization domain 2 (NOD2). The underlying mechanisms of Blau syndrome leading to autoinflammation are still unclear, and there is currently no effective specific treatment for Blau syndrome. Objectives: To elucidate the mechanisms of autoinflammation in Blau syndrome, we sought to clarify the relation between disease associated-mutant NOD2 and the inflammatory response in human samples. Methods: Blau syndrome-specific induced pluripotent stem cells (iPSCs) lines were established. To precisely evaluate the in vitro phenotype of iPSC-derived cells, the disease-associated NOD2 mutation of iPSCs was corrected using a CRISPR/Cas9 system. We also introduced the same NOD2 mutation into a control iPSC line. These isogenic iPSCs were then differentiated into monocytic cell lineages, and the status of NF-?B pathway and proinflammatory cytokine secretion were investigated. Results: We focused on the signals that upregulate the expression of NOD2, especially IFN-? signaling. IFN-? treatment of NOD2-mutant macrophages induced ligand-independent NF-?B activation and proinflammatory cytokine production. IFN-? treatment acted as a priming signal through the up-regulation of NOD2 protein and recruitment of NOD2 on the basement membrane. Conversely, the production of proinflammatory cytokines by MDP, a ligand of NOD2, was decreased in mutant macrophages. Conclusions: Our data support the significance of ligand-independent autoinflammation in the pathophysiology of Blau syndrome. Our comprehensive isogenic disease-specific iPSC panel provides a useful platform for probing therapeutic and diagnostic clues for the treatment of Blau syndrome patients. Overall design: RNA-sequencing was conducted to identify the genes expressed in reponse to stimulation in different manners between WT and MT cells

Description
Identification of cancer stem/initiating cells (CSCs/CICs) by a specific marker is useful for diagnosis and therapy of cancer. We have determined that PSF1 which plays a role in DNA replication in lower species is strongly expressed in wide range of normal stem cell population. Here, utilizing the transcriptional activity of PSF1 promoter in tumor cell xenograft model, we show that PSF1high cancer cells display malignant features including high proliferating activity, serial transplantation potential, and metastatic ability those are used for criteria of CSCs/CICs. PSF1high cancer cells localize in perivascular region and genetically display ES cell like signature. Silencing of PSF1 by RNAi inhibited growth of cancer cells mediated by disruption of DNA synthesis and chromosomal segregation. These suggested that PSF1 is a possible maker and a molecular target of CSCs/CICs.

Description
Purpose: RNA-Seq analysis can help identify large set of differentially expressed genes at a time. We performed RNA-Seq analysis to identify differentially expressed genes in the PBMCs of war veterans suffering from PTSD. Methods: Total RNA from PBMCs from PTSD +ve and -ve individuals were used for RNA-Seq analysis. Results: We obtained, on average, ~60 millions reads per sample. More than 70% of the reads were mapped to human genome. Functional analysis of the differentially expressed genes (362) revealed dysregulation in immune system network. Conclusions: Our present study provides further proof that immune system related genes and pathways are dysregulated in PTSD PBMCs. Overall design: RNA-Seq was performed with RNA from 5 each control and PTSD individuals. PBMCs collected within one hour of blood draw were used for RNA isolation. 1 ug of total RNA was used for library synthesis and sequenced in a HighSeq 2000 illumina instrument at Tufts University.
