It is known that the level of protein-conjugated acrolein in plasma is a good marker of chronic renal failure and brain infarction. Thus, studies were carried out to determine which kinds of plasma proteins are conjugated with acrolein. It was found that acrolein was mainly conjugated with albumin. Tandem mass spectrometry analysis demonstrated that Lys-557(More)
Neuroblastoma (NB) is one of the most frequent solid tumors in children and its prognosis is still poor. The neurotrophin receptor TrkB and its ligand brain-derived neurotrophic factor (BDNF) are expressed at high levels in high-risk NBs and are involved in defining the poor prognosis of the patients. However, the TrkB targeting therapy has never been(More)
Liposomally formulated indocyanine green (LP-ICG) has drawn much attention as a highly sensitive near-infrared (NIR)-fluorescence probe for tumors or lymph nodes in vivo. We synthesized ICG derivatives tagged with alkyl chains (ICG-Cn), and we examined NIR-fluorescence imaging for lymph nodes in the lower extremities of mice by using liposomally formulated(More)
Polyamines play important roles in cell growth mainly through their interaction with RNA. We have previously reported that polyamines stimulate the synthesis of oligopeptide-binding protein OppA in Escherichia coli and the formation of Ile-tRNA in rat liver (Igarashi, K., and Kashiwagi, K. (2000) Biochem. Biophys. Res. Commun. 271, 559-564). These effects(More)
We have rationally designed and synthesized a novel near-infrared (NIR) photoactivating probe, designated by iDOPE, in which an indocyanine green (ICG) fluorophore is covalently conjugated with a phospholipid moiety, 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), to incorporate into liposome bilayers. NIR irradiation showed that iDOPE retained the(More)
The survival of patients with primary CNS lymphoma (PCNSL) has been improved by high-dose methotrexate (HD-MTX). Since the combination therapy of HD-MTX and whole-brain radiotherapy (WBRT) carries a significant risk for delayed neurotoxicity, it is important to know the therapeutic potential and prognostic factors for HD-MTX without WBRT. We retrospectively(More)
Calmodulin (CaM)-dependent protein kinase (CaM kinase) is proposed to regulate the type alpha of cytosolic phospholipase A(2) (cPLA(2)alpha), which has a dominant role in the release of arachidonic acid (AA), via phosphorylation of Ser515 of the enzyme. However, the exact role of CaM kinase in the activation of cPLA(2)alpha has not been well established. We(More)
The aim of this study was to assess whether modulated electro-hyperthermia (mEHT) can induce an abscopal effect and thereby enhance the antitumor effects of immunotherapy. We used an intratumoral dendritic cell (DC) injection and mEHT to treat C3H/He mice inoculated with squamous cell carcinoma SCCVII cells in the left leg, and we assessed the whole body(More)
Mastermind (Mam) is one of the elements of Notch signaling, a system that plays a pivotal role in metazoan development. Mam proteins form transcriptionally activating complexes with the intracellular domains of Notch, which are generated in response to the ligand-receptor interaction, and CSL DNA-binding proteins. In mammals, three structurally divergent(More)
BACKGROUND/AIM Although conventional staging laparoscopy (SL) has improved the diagnostic accuracy of peritoneal dissemination, novel technology is needed to increase the sensitivity of SL. We herein describe a new imaging method employing near-infrared (NIR) fluorescence imaging using a liposomal synthesized indocyanine green (ICG) liposomal derivative,(More)
