Abstract
We investigated the inhibitory effect of osthole on myocardial fibrotic formation in mice and its possible mechanisms. A mouse model with myocardial fibrosis was induced by hypodermic injection of isoprenaline while the mice were simultaneously treated with 40 and 80 mg/kg osthole for 40 days. After...

Abstract
We show that Fgf8 and Sema3f, produced by early dental epithelium, respectively, attract and repulse mesenchymal cells, which cause them to pack tightly together during mouse tooth development. Resulting mechanical compaction-induced changes in cell shape induce odontogenic transcription factors (Pa...

Abstract
We generated and characterized Atxn1L(-/-) and Atxn1(-/-); Atxn1L(-/-) mice. Atxn1L(-/-) mice have hydrocephalus, omphalocele, and lung alveolarization defects. These phenotypes are more penetrant and severe in Atxn1(-/-); Atxn1L(-/-) mice, suggesting that ATXN1 and ATXN1L are functionally redundan...

Abstract
We identified an alternative mode of cytokinin action that uses endocytic trafficking as a means to direct plant organogenesis. This activity occurs downstream of known cytokinin receptors but through a branch of the cytokinin signaling pathway that does not involve transcriptional regulation. We sh...

Gene expression profiles of paired hepatocellular carcinoma (HCC) and adjacent noncancerous liver tissue samples revealed preferential expression of midkine in HCC. This finding suggested the clinical usefulness of midkine measurement in serum for monitoring HCC treatment response, recurrence, and pr...

Abstract
Dendritic cells (DCs) are critical in initiating immune responses by cross-priming of tumor Ags to T cells. Previous results showed that NK cells inhibited DC-mediated cross-presentation of tumor Ags both in vivo and in vitro. In this study, enhanced Ag presentation was observed in draining lymph nod...

Interestingly, Ag-specific IgA Ab-...

Abstract

We hypothesized that the NLRP3/caspase-1/IL-1β pathway is critical in DEP-induced lung inflammation. Upon DEP exposure, IL-1RI knockout mice had reduced pulmonary inflammation compared with wild-type mice. Similarly, treatment with rIL-1R antagonist (anakinra) and IL-1β neutralization impaired the...

We report that CD86 is ubiquitinated in DCs via MARCH1 E3 ubiquitin ligase and that this ubiquitination plays a key role in CD86 regulation. Ubiquitination at lysine 267 played the most critical role for this regulation. CD86 is ubiquitinated in MARCH1-deficient DCs to a much lesser degree than in w...

We examined the effect of PHD inhibition on the expression of angiotensin II type 1 receptor (AT(1)R). Hypoxia, cobalt chloride, and dimethyloxalylglycine, all known to inhibit PHD, reduced AT(1)R expression in vascular smooth muscle cells.

We show that in both RAW264.7 macrophage cells and primary bone marrow-derived macrophages, the production of IFN-β and IL-6, but not TNF, in response to cyclic-di-AMP and cyclic-di-GMP requires MPYS (also known as STING, MITA, and TMEM173). Furthermore, expression of MPYS was required for IFN resp...
