Journal ArticleDOI
Alteration of biochemical and pathological properties of TDP-43 protein by a lipid mediator, 15-deoxy-Δ12,14-prostaglandin J2
Hai-Xin Zhang,Kunikazu Tanji,Hidemi Yoshida,Makoto Hayakari,Takahiro Shibata,Fumiaki Mori,Koji Uchida,Koichi Wakabayashi +7 more
TL;DR: Biochemical and immunocytochemical analyses showed that 15d-PGJ(2) affects the proteolysis, solubility, and subcellular localization of TDP-43, similar to alterations found in T DP-43 proteinopathy, and suggest that 14-Deoxy-Delta(12,14)-prostaglandin J(2), non-enzymatically produced from PGD(2).
Journal ArticleDOI
Alteration of mitochondrial protein PDHA1 in Lewy body disease and PARK14.
TL;DR: PDHA1 is reported as a new component of brainstem-type Lewy bodies in idiopathic PD, DLB and PARK14, the level of PDHA1 protein being significantly decreased in the putamen and substantia nigra of patients with idiopathy PD, suggesting that alteration of glucose metabolism through dysfunction of the PDH complex might occur in the pathogenesis of Lewy body disease and PARK 14.
Journal ArticleDOI
Platelet-activating factor enhances the expression of nerve growth factor in normal human astrocytes under hypoxia.

TL;DR: It is concluded that PAF enhances NGF gene expression in human astrocytes, and the PAF-induced increase in the expression of NGF under hypoxia may benefit the protection of the nervous tissue by promoting neuronal survival.
Journal ArticleDOI
Gnetin C, a resveratrol dimer, reduces amyloid-β 1-42 (Aβ42) production and ameliorates Aβ42-lowered cell viability in cultured SH-SY5Y human neuroblastoma cells.
Syota Seino,Takeru Kimoto,Hidemi Yoshida,Kunikazu Tanji,Tomoh Matsumiya,Ryo Hayakari,Kazuhiko Seya,Shogo Kawaguchi,Kazushi Tsuruga,Hiroshi Tanaka,Tadaatsu Imaizumi +10 more
TL;DR: Gnetin C may prevent Aβ toxicity by suppressing BACE1 and enhancing MMP-14, together with reducing both internalization and oligomerization of exogenous Aβ monomers, and lead to the prevention of Aβ-mediated diseases, particularly AD.
Journal ArticleDOI
Interferon (IFN)-induced protein 35 (IFI35) negatively regulates IFN-β-phosphorylated STAT1-RIG-I-CXCL10/CCL5 axis in U373MG astrocytoma cells treated with polyinosinic-polycytidylic acid.
Kyogo Shirai,Taku Shimada,Hidemi Yoshida,Ryo Hayakari,Tomoh Matsumiya,Kunikazu Tanji,Manabu Murakami,Hiroshi Tanaka,Tadaatsu Imaizumi +8 more
TL;DR: The results suggest that IFI 35 may negatively regulate the TLR3-IFN-β-P-STAT1-RIG-I-CXCL10/CCL5 axis in U373MG cells, and IFI35 may play a role at least partially in the regulation of innate immune reactions in astrocytes.
