Description
To recruit phagocytes, apoptotic cells characteristically release ATP, which functions as a danger signal. Here, we found that the culture supernatant of apoptotic cells activated the macrophages to express anti-inflammatory genes such as NR4A and Thbs1. A high level of AMP accumulated in the apoptotic cell supernatant in a Pannexin1-dependent manner. A nucleotidase inhibitor and A2a adenosine receptor antagonist inhibited the apoptotic supernatant-induced gene expression, suggesting AMP was metabolized to adenosine by an ecto-5-nucleotidase expressed on macrophages, to activate the macrophage A2a adenosine receptor. Intraperitoneal injection of zymosan into AdoR A2a- or Panx1-deficient mice produced high, sustained levels of inflammatory mediators in the peritoneal lavage. These results indicated that AMP from apoptotic cells suppresses inflammation as a calm down signal.

Description
We demonstrated that, four weeks after the pulmonary artery banding (PAB) operation, rats could be divided into two groups: an F+ group in which the fibrotic area occupied more than 6.5% of the whole area of the heart tissues, and an F- group in which the fibrotic area occupied less than 6.5% of this area.

Description
We describe a critical role for Cdk6 in JAK2V617F+ MPN evolution. The absence of Cdk6 ameliorates clinical symptoms and prolongs survival of JAK2V617F fl/+ vav-Cre mice. The Cdk6 protein interferes with three hallmarks of disease: besides regulating malignant stem cell quiescence, it promotes NFkB signaling and contributes to cytokine production while inhibiting apoptosis. The treatment with palbociclib did not mirror these effects, showing that the functions of Cdk6 in MPN pathogenesis are largely kinase-independent. Overall design: LSK-sorted (FACS) bone marrow cells from 8-week-old VavCre;Jak2+/+; Cdk6+/+, VavCre;Jak2V617F; Cdk6+/+, VavCre;Jak2V617F; Cdk6-/-, VavCre; Jak2+/+; Cdk6-/- mice, and the same cell type from palbociclib-treated (38mg/kg, 3x in one week) VavCre;Jak2V617F; Cdk6+/+ mice, n=3 for all genotypes

Description
Ensuring cooperation among formerly autonomous cells has been a central challenge in the evolution of multicellular organisms. One solution is monoclonality, but this option does not eliminate genetic and epigenetic variability, leaving room for exploitative behavior. We therefore hypothesized that embryonic development must be protected by robust regulatory mechanisms that prevent aberrant clones from superseding wild-type cells. Using a genome-wide screen in murine induced pluripotent stem cells, we identified a network of genes (centered on p53, topoisomerase 1, and olfactory receptors) whose downregulation caused the cells to replace wild-type cells, both in vitro and in the mouse embryowithout perturbing normal development. These genes thus appear to fulfill an unexpected role in fostering cell cooperation.

Description
The overall goal of this project is to investigate the role of TGF-beta signaling in epithelial cells as it pertains to the orientation of muscle fibers in the soft palate during embryogenesis. Here, we first conducted gene expression profiling of the anterior and posterior portions of the palate from wild-type mice. In addition, we also conducted gene expression profiling of the posterior palate in mutant mice with an epithelium-specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of submucosal cleft palate, which is a congenital birth defect commonly observed in many syndromic conditions.

Description
Steroid and xenobiotic receptor (SXR) and its murine ortholog pregnane X receptor (PXR) are nuclear receptors that are expressed mainly in the liver and the intestine. They function as xenobiotic sensors by inducing genes involved in detoxification and drug excretion. Recent evidence showed that SXR and PXR are also expressed in bone tissue where they mediate bone metabolism. Here we report that systemic deletion of PXR results in aging-dependent wearing of articular cartilage of knee joints. Histomorphometrical analysis showed remarkable reduction of width and an enlarged gap between femoral and tibial articular cartilage in PXR knockout mice. We hypothesized that genes induced by SXR in chondrocytes have a protective effect on articular cartilage and identified Fam20a (family with sequence similarity 20a) as an SXR-dependent gene induced by the known SXR ligands, rifampicin and vitamin K2. Lastly, we demonstrated the biological significance of Fam20a expression in chondrocytes by evaluating osteoarthritis-related gene expression of primary articular chondrocytes. Consistent with epidemiological findings, our findings indicate that SXR/PXR protects against aging-dependent wearing of articular cartilage and that ligands for SXR/PXR have potential role in preventing osteoarthritis caused by aging.
