Soluble epoxide hydrolase maintains steady-state lipid turnover linked with autocrine signaling in peritoneal macrophagesLiu F, Diao X, Cong H, Suzuki E, Hasumi K, Takeshima H
iScience
Cell press
Soluble epoxide hydrolase is a widely distributed bifunctional enzyme that contains N-terminal phosphatase (N-phos) and C-terminal epoxide hydrolase (C-EH) domains. C-EH hydrolyzes anti-inflammatory epoxy-fatty acids to corresponding diols and contributes to various inflammatory conditions. However, N-phos has been poorly examined. In peritoneal macrophages, the N-phos inhibitor amino-hydroxybenzoic acid (AHBA) seemed to primarily interrupt the dephosphorylation of lysophosphatidates and broadly attenuated inflammation-related functions. AHBA activated intrinsic lysophosphatidate and thromboxane A2 receptors by altering lipid-metabolite distribution; downstream the signaling, phospholipase C was facilitated to dampen intracellular Ca2+ stores and AKT kinase (protein kinase B) was activated to presumably inhibit inflammatory gene expression. Our data suggest that N-phos maintains steady-state phospholipid turnover connecting autocrine signaling and is a prospective target for controlling inflammatory responses in macrophages.

Soluble epoxide hydrolase (EC 3.3.2.10) is a key enzyme in the regulation of inflammation and metabolism, whereas, the role of its N-terminal phosphatase activity (N-phos) has been poorly understood because of a lack of selective inhibitors. Here we report 4-aminobenzoic (K-i 15.3 mu m) and 3-amino-4-hydroxy benzoic acid (K-i 11.7 mu m) as selective competitive inhibitors of N-phos.

Direct cellーcell interaction regulates division of stem cells from PC-3 human prostate cancer cell lineSuzuki E. Masaka N, Urabe T, Sasaki M, Hasumi K.
Biochem. Biophys. Res. Commun.
ACADEMIC PRESS INC ELSEVIER SCIENCE
Cancer stem cells (CSCs) are a subpopulation that can drive recurrence and metastasis. Therefore, therapies targeting CSCs are required. Although previous findings have suggested that non-CSCs regulate the proliferation and differentiation of CSCs in the tumor microenvironment, the precise molecular mechanism is largely unknown. In this study, we found that a direct interaction between CSCs and non-CSCs downregulated CSC division in the PC-3 human prostate cancer cell line. We found that the pro-liferation of PC-3-derived CSCs (PrSCs) was significantly decreased (similar to 47%) in the presence of non-CSC -rich parental PC-3 cells compared with that in a culture in which they were absent. We observed no differences in PrSC proliferation when we indirectly cocultured them with PC-3 cells across a Transwell insert, and PrSCs that were transiently bound to immobilized PC-3 cells proliferated more slowly than those bound to PrSCs. The frequency of cell division with prior PrSC-PrSC contact was 2.8 times higher in the PrSC monoculture compared with that in the coculture with PC-3 cells. We found that the PrSCs were approximately 1.3 times more closely associated in the monoculture compared with the coculture with PC-3 cells, as determined by a cell proximity assay. The frequency of asymmetric PrSC division was 6.5% in the monoculture compared with 1.0% in the coculture with PC-3 cells (P < 0.045). By analyzing our data, we determined the importance of PrSC-non-CSC contact in regulating the frequency and mode of PrSC division. This regulation might be a valuable target for treating cancer.

Amine-regulated pri-SMTP oxidation in the SMTP biosynthesis in Stachybotrys as a nitrogen acquisition strategyIwama R, Sasano Y, Hiramatsu T, Otake S, Suzuki E, Hasumi K.
Journal of Fungi
MDPI
SMTP (the name SMTP is derived from Stachybotrys microspora triprenyl phenol) is a family of triprenyl phenol secondary metabolites from a black mold, Stachybotrys microspora. Some SMTP congeners exhibit anti-inflammatory and profibrinolytic activities that, in combination, contribute to the treatment of ischemic stroke. The final step in the SMTP biosynthesis is a non-enzymatic amine conjugation with an o-phthalaldehyde moiety of the precursor pre-SMTP, which can form adducts with proteins and nucleic acids. Thus, pre-SMTP formation should be a precisely regulated, rate-limiting step in the SMTP biosynthesis. To address the mechanism backing this regulation, we purified a metabolite that rapidly disappeared following amine feeding, identifying a novel compound, pri-SMTP. Furthermore, an enzyme, designated as pri-SMTP oxidase, responsible for pri-SMTP conversion to pre-SMTP, was purified. The formation of pri-SMTP, which is regulated by nitrogen and carbon nutrients, occurred in particular septate mycelia. Although pri-SMTP oxidase was expressed constitutively, the consumption of pri-SMTP was accelerated only when a primary amine was fed. Thus, SMTP biosynthesis is regulated by at least three mechanisms: (i) pri-SMTP formation affected by nutrients, (ii) the compartmentalization of pri-SMTP formation/storage, and (iii) amine-regulated pri-SMTP oxidation. Amine-regulated SMTP formation (i.e., amine-capturing with pre-SMTP) may play a role in the nitrogen acquisition/assimilation strategy in S. microspora, since pri-SMTP synthesis occurs on non-preferred nitrogen.

Impact of SMTP targeting plasminogen and soluble epoxide hydrolase on thrombolysis, inflammation, and ischemic strokeHasumi K, Suzuki E
International Journal of Molecular Sciences
MDPI
Stachybotrys microspora triprenyl phenol (SMTP) is a large family of small molecules derived from the fungus S. microspora. SMTP acts as a zymogen modulator (specifically, plasminogen modulator) that alters plasminogen conformation to enhance its binding to fibrin and subsequent fibrinolysis. Certain SMTP congeners exert anti-inflammatory effects by targeting soluble epoxide hydrolase. SMTP congeners with both plasminogen modulation activity and anti-inflammatory activity ameliorate various aspects of ischemic stroke in rodents and primates. A remarkable feature of SMTP efficacy is the suppression of hemorrhagic transformation, which is exacerbated by conventional thrombolytic treatments. No drug with such properties has been developed yet, and SMTP would be the first to promote thrombolysis but suppress disease-associated bleeding. On the basis of these findings, one SMTP congener is under clinical study and development. This review summarizes the discovery, mechanism of action, pharmacological activities, and development of SMTP.

Kurozu melanoidin, a novel oligoglucan-melanoidin complex from Japanese black vinegar, suppresses adipogenesis in vitroSuzuki, Eriko; Otake, Shinya; Hamadate, Naobumi; Hasumi, Keiji
JOURNAL OF FUNCTIONAL FOODS
ELSEVIER
The black vinegar kurozu has an anti-obesity potential, but its active principle is unknown. Here, we isolate and characterize a novel oligoglucan-melanoidin complex, designated kurozu melanoidin (KZM), that suppresses adipogenesis in vitro. KZM was isolated by organic solvent extraction, followed by size-exclusion chromatography. Its average molecular mass was estimated to be 1,090 +/- 30 Da using polyethylene glycols as standards. The combination of spectroscopic and chemical analyses revealed the presence of an oligoglucan and a melanoidin structures in KZM. The glucan moiety consisted mainly of 1 -> 4 linkage. The MALDI-TOF-MS analysis identified an array of ion peaks that differed in m/z by similar to 162.055 [C6H12O6 - H2O], indicating a variation of glucan chain length. Prominent signals around m/z 500-600 that were unassignable to glucan units suggested ion peaks for the melanoidin moiety. KZM significantly suppressed adipogenesis of 3T3-L1 preadipocytes at 100 mu M.

Unsaturated fatty acids enhance the fibrinolytic activity of subtilisin NAT (nattokinase)Takagaki, Soichiro; Suzuki, Maiko; Suzuki, Eriko; Hasumi, Keiji
JOURNAL OF FOOD BIOCHEMISTRY
WILEY
Subtilisin NAT (STN), alternatively designated nattokinase, is a serine protease with potent fibrinolytic activity. In this study, we screened several foods to enhance the fibrinolytic potential of STN and identified unsaturated fatty acid-rich ones as candidates. We isolated linoleic acid as a major active compound from one of the most active foods, red pepper. Linoleic acid promoted the STN-mediated fibrin/fibrinogen degradation at >20 mu g/ml. STN cleaved three of the fibrinogen polypeptide chains, among which linoleic acid accelerated B beta-chain and gamma-chain degradations, but slightly suppressed the degradation of alpha-chain fragments. Linoleic acid failed to affect small synthetic peptide degradation, suggesting a conformational modulation of fibrin/fibrinogen for the linoleic acid promotion of STN activity. Of the various fatty acids tested, unsaturated ones were active but saturated ones were rather inhibitory to STN-mediated fibrinolysis. Thus, our data shed new light on the dietary promotion of STN activity. Practical applications Subtilisin NAT (STN) is a serine protease abundantly contained in natto, a soybean food fermented withBacillus subtilisvar.natto. The use of STN as functional foods to improve blood circulation is getting attention because STN actively degrades fibrin. Our results demonstrate that widely occurring unsaturated fatty acids such as linoleic, eicosapentaenoic, and docosahexaenoic acids enhance the fibrinolytic activity of STN. Thus, the intake of natto or STN supplements in combination with unsaturated fatty acid-containing oil can be a novel way to gain cardiovascular benefits.

N-Substituted amino acid inhibitors of the phosphatase domain of the soluble epoxide hydrolaseMatsumoto, Naoki; Kataoka, Masaki; Hirosaki, Hibiki; Morisseau, Christophe; Hammock, Bruce D.; Suzuki, Eriko; Hasumi, Keiji
BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS
ACADEMIC PRESS INC ELSEVIER SCIENCE
The soluble epoxide hydrolase (sEH) is a bifunctional enzyme implicated in the regulation of inflammation. The N-terminal domain harbors a phosphatase activity (N-phos) with an affinity to lipid phosphomonoesters, and the C-terminal domain has an activity to hydrolyze anti-inflammatory lipid epoxides (C-EH). Although many potent inhibitors of C-EH have been discovered, little is known about inhibitors of N-phos. Here, we identify N-substituted amino acids as selective inhibitors of N-phos. Many of the N-substituted amino acids inhibited differently mouse and human N-phos; phenylalanine derivatives are relatively selective for mouse N-phos, whereas tyrosine derivatives are more selective for human N-phos. The best inhibitors, Fmoc-L-Phe(4-CN) (67) and Boc-L-Tyr(Bzl) (23), inhibited mouse and human N-phos competitively with K-I in the low micromolar range. These compounds inhibit the N-phos activity 37- (67) and 137-folds (23) more potently than the C-EH. The differences in inhibitor structure activity suggest different active site structure between species, and thus, probably a divergent substrate preference between mouse and human N-phos.

Background: Stachybotrys microspora triprenyl phenol-7 (SMTP-7) has both thrombolytic and anti-inflammatory effects, but its neuroprotective effects on cerebral ischemia are still unclear. The present study assessed the antioxidative and neurovascular unit (NVU) protective effects of SMTP-7 using transient middle cerebral artery occlusion (tMCAO) mice. Methods: After 60 minutes tMCAO, 0.9% NaC1, tissue-type plasminogen activator (tPA), SMTP-7 or tPA + SMTP-7 was intravenously administrated through subclavian vein just before the reperfusion, and these mice were examined at 24 hours after reperfusion. We histologically assessed the hemorrhage and expressive changes of antioxidative markers in brains. Results: SMTP-7 treatment showed a similar antithrombotic effect to tPA, but significantly decreased the hemorrhage volumes and the number of 4-HNE, 3-NT and 8-OHdG positive cells, meanwhile, ameliorated the decrease of collagen IV in the ischemic brains. However, tPA + SMTP-7 treatment did not decrease hemorrhage volumes nor showed NVU protective effect. Conclusions: The present study suggested that SMTP-7 provided therapeutic benefits for ischemic stroke through antioxidative and NVU protective effects unlike tPA alone or tPA + SMTP-7.

Background: Stachybotrys microspora triprenyl phenol-7 (SMTP-7) has both potentials of thrombolytic and neuroprotective effects, but its detailed neuroprotective mechanisms in ischemic stroke are still unclear. Here, we assessed the neuroprotective effects of SMTP-7 for anti-inflammatory and antiapoptosis mechanisms after 60 minutes of transient middle cerebral artery occlusion (tMCAO) in mice. Methods: After 60 minutes of tMCAO, 0.9% NaCl, tissue-type plasminogen activator (tPA), SMTP-7 or tPA+SMTP-7 was intravenously administrated through subclavian vein just before the reperfusion, and these mice were examined at 24 hours after reperfusion. We histologically assessed the antineuroinflammatory effect of SMTP-7 on the expressive changes of inflammatory markers in ischemic mouse brains. Results: Compared with the vehicle and tPA groups, SMTP-7 treatment significantly improved clinical scores and decreased the infarct volume and the numbers of TNE-alpha, nuclear factor-kappa B (NF-kappa B), nucleotide oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3), and cleaved caspase-3-positive cells in the brain of mice at 24 hours after tMCAO but not p62-positive cells. However, tPA+SMTP-7 treatment did not show such effects. Conclusions: The present study suggested that SMTP-7 provides a therapeutic benefit for ischemic stroke mice through anti-inflammatory and antiapoptotic effects but not antiautophagic effect.
