Transient nuclear factor kappaB (NF-kappaB) activation stimulated by interleukin-1beta may be partly dependent on proteasome activity, but not phosphorylation and ubiquitination of the IkappaBalpha molecule, in C6 glioma cells. Regulation of NF-kappaB linked to chemokine production.

We previously reported that several stresses can induce cytokine-induced neutrophil chemoattractant expression in a nuclear factor kappaB (NF-kappaB)-dependent manner. In this study, we focused further on the regulation of NF-kappaB. The activation of NF-kappaB and the subsequent cytokine-induced neutrophil chemoattractant induction in response to interleukin-1beta (IL-1beta) were inhibited by proteasome inhibitors, MG132 and proteasome inhibitor I. Translocation of NF-kappaB into nuclei occurs by the phosphorylation, multi-ubiquitination, and degradation of IkappaBalpha, a regulatory protein of NF-kappaB. Nascent IkappaBalpha began to degrade 5 min after treatment with IL-1beta and disappeared completely after 15 min. However, IkappaBalpha returned to basal levels after 45-60 min. Interestingly, resynthesized IkappaBalpha was already phosphorylated at Ser-32. These results suggest that 1) the upstream signals are still activated, although the translocation of NF-kappaB peaks at 15 min; and 2) the regulated protein(s) acts downstream of IkappaBalpha phosphorylation. Western blotting showed that the resynthesized and phosphorylated IkappaB molecules were also upward-shifted by multi-ubiquitination in response to IL-1beta treatment. On the other hand, ATP-dependent Leu-Leu-Val-Tyr cleaving activity transiently increased, peaked at 15 min, and then decreased to basal levels at 60 min. Furthermore, the cytosolic fraction that was stimulated by IL-1beta for 15 min, but not for 0 and 60 min, could degrade phosphorylated and multi-ubiquitinated IkappaBalpha. These results indicate that the transient translocation of NF-kappaB in response to IL-1beta may be partly dependent on transient proteasome activation.

Possible involvement of p38 MAP kinase in HSP70 expression induced by hypoxia in rat primary astrocytes.

The aim of this study was to elucidate the possible mechanism of HSP induction in response to hypoxia in rat primary astrocytes. Treatment with SB203580, a selective p38 MAP kinase (p38 MAPK) inhibitor, attenuated the increase in HSP70 in a concentration-dependent manner. p38 MAPK was activated in response to hypoxic treatment. These results suggest that p38 MAPK positively regulates hypoxia-induced HSP70 expression in astrocytes.

Biochemical nature and cellular distribution of the paired immunoglobulin-like receptors, PIR-A and PIR-B.

PIR-A and PIR-B, paired immunoglobulin-like receptors encoded, respectively, by multiple Pira genes and a single Pirb gene in mice, are relatives of the human natural killer (NK) and Fc receptors. Monoclonal and polyclonal antibodies produced against a recombinant PIR protein identified cell surface glycoproteins of approximately 85 and approximately 120 kD on B cells, granulocytes, and macrophages. A disulfide-linked homodimer associated with the cell surface PIR molecules was identified as the Fc receptor common gamma (FcRgammac) chain. Whereas PIR-B fibroblast transfectants expressed cell surface molecules of approximately 120 kD, PIR-A transfectants expressed the approximately 85-kD molecules exclusively intracellularly; PIR-A and FcRgammac cotransfectants expressed the PIR-A/ FcRgammac complex on their cell surface. Correspondingly, PIR-B was normally expressed on the cell surface of splenocytes from FcRgammac-/- mice whereas PIR-A was not. Cell surface levels of PIR molecules on myeloid and B lineage cells increased with cellular differentiation and activation. Dendritic cells, monocytes/macrophages, and mast cells expressed the PIR molecules in varying levels, but T cells and NK cells did not. These experiments define the coordinate cellular expression of PIR-B, an inhibitory receptor, and PIR-A, an activating receptor; demonstrate the requirement of FcRgammac chain association for cell surface PIR-A expression; and suggest that the level of FcRgammac chain expression could differentially affect the PIR-A/PIR-B equilibrium in different cell lineages.

Chemical design of radiolabeled antibody fragments for low renal radioactivity levels.

The renal uptake of radiolabeled antibody fragments presents a problem in targeted imaging and therapy. We hypothesized that the renal radioactivity levels of radiolabeled antibody fragments could be reduced if radiolabeled compounds of urinary excretion were released from glomerularly filtered antibody fragments before they were incorporated into renal cells by the action of brush border enzymes, present on the lumen of renal tubules. 3'-[131I]Iodohippuryl N(epsilon)-maleoyl-L-lysine ([131I]HML) was conjugated with a thiolated Fab fragment because the glycyl-lysine sequence in HML is a substrate for a brush border enzyme and metaiodohippuric acid is released by cleavage of the linkage. Fab fragments were also radiolabeled by direct radioiodination (125I-Fab) or by conjugation with meta-[125I]-iodohippuric acid via an amide bond [N-(5-maleimidopentyl) 3'-iodohippuric acid amide ([125I]MPH-Fab)] or an ester bond [maleimidoethy 3'-iodohippurate ([125I]MIH-Fab)] by procedures similar to those used for [131I]HML-Fab. In biodistribution experiments in mice, [131I]HML-Fab demonstrated markedly low renal radioactivity levels with kidney:blood ratios of radioactivity of 1 from 10 min to 1 h due to rapid release of meta-[131I]iodohippuric acid. [125]MIH-Fab and 1251-Fab reached their peak ratios of 3.8 and 7.3 at 1 h, respectively, and [125I]MPH-Fab showed the maximum ratio of 16.8 at 6 h. In subcellular distribution studies, both [125I]MIH-Fab and 125I-Fab showed migration of radioactivity from the membrane to the lysosomal fraction of the renal cells from 10 to 30 min postinjection, whereas the majority of the radioactivity was detected only in the membrane fraction after administration of [131I]HML-Fab at both time points. In nude mice, [131I]HML-Fab showed one-quarter of the renal radioactivity of simultaneously administered 125I-Fab without impairing the target radioactivity levels 3 h after injection. These findings indicated that HML is a useful reagent for targeted imaging and therapy using antibody fragments as vehicles. These findings also suggested that the radiochemical design of radiolabeled antibody fragments that liberate radiometabolites of urinary excretion from antibody fragments by the action of brush border enzymes may constitute a new strategy for reducing the renal radioactivity levels of antibody fragments.

Diffuse schwannoma involving the entire large bowel with huge extramural development: report of a case.

Schwannoma of the large bowel is a rare clinical entity, which has reportedly been recognized to arise from one place with a submucosal tumor morphology. We present herein the unique case of a 25-year-old woman who suffered from a schwannoma diffusely involving the entire large intestine. The patient complained of abdominal distension and imaging studies revealed a giant tumor occupying the whole abdomen, but no confirmed preoperative diagnosis could be made. A laparotomy proved the huge tumor detected preoperatively to be the markedly wall-thickened entire large bowel itself due to the diffuse extramural development of a neoplasm, but no other organs were involved. Biopsy specimens from the tumor were histologically diagnosed as benign schwannoma. However, because of the possibility of malignancy, we later performed a total proctocolectomy followed by an ileal J-pouch-anal canal anastomosis. The final pathological diagnosis was also that of a benign schwannoma originating from the large intestine. The patient remains well without recurrence 15 months after surgery. To the best of our knowledge, no such case of a schwannoma in the entire large bowel has yet been reported in the literature, and the pathogenesis of its occurrence remains unknown.

Neuroprotective effects of a dihydropyridine derivative, 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarbox ylic acid methyl 6-(5-phenyl-3-pyrazolyloxy)hexyl ester (CV-159), on rat ischemic brain injury.

CV-159, 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylic++ + acid methyl 6-(5-phenyl-3-pyrazolyloxy)hexyl ester, is a dihydropyridine derivative that blocks the L-type Ca2+ channel and inhibits the calmodulin (CaM)-dependent pathway. In this study, we examined the effects of CV-159 on rat ischemic brain injury. CV-159 (5 and 10 mg/kg, p.o.) gave significant protection against delayed neuronal death in the hippocampal CA1 region after 15-min transient forebrain ischemia. In contrast, the Ca2+ antagonists nicardipine (1 and 10 mg/kg, p.o.) and nifedipine (1 mg/kg, i.p.) and the CaM antagonist N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7, 500 ng, i.c.v.) had no effect on this hippocampal neuronal death. CV-159 also diminished the size of the brain infarct after permanent middle cerebral artery (MCA) occlusion, although physiological variables, including regional cerebral blood flow, were not affected. The increase in the water content of the infarcted cortex induced by MCA occlusion was significantly reduced by CV-159. On the other hand, neither nicardipine nor nifedipine affected the brain infarct size, volume or increased water content induced by MCA occlusion, as previously reported (A. Sauter and M. Rudin, Am. J. Hypertens. 4 121S-127S, 1991). These findings indicate that Ca2+ antagonists, such as nicardipine and nifedipine, and W-7 have no effect on rat ischemic brain injury. The results suggest that CV-159 protects against ischemic brain injury. This might be mediated by both blocking the L-type Ca2+ channel and inhibiting CaM-dependent function via Ca2+/CaM binding at a different binding site from that of W-7 to CaM (H. Umekawa, K. Yamakawa, K. Nunoki, N. Taira, T. Tanaka, and H. Hidaka, Biochem. Pharmacol. 37 3377-3381, 1988).

Temperament and character inventory dimensions as a predictor of response to antidepressant treatment in major depression.

BACKGROUND: Cloninger's theory of personality, including 4 temperament dimensions and 3 character dimensions, is one of the most noteworthy theories in recent years. Several studies have explored temperament dimensions as a predictor of response to antidepressant treatments in major depression, but these have provided inconsistent results. The present study explored temperament as well as character dimensions, as measured by the Temperament and Character Inventory (TCI), as possible predictors of response to maprotiline, the most-widely prescribed antidepressant in Japan. METHODS: 86 consecutive patients with major depression underwent a 16-week open trial of maprotiline. They filled out the TCI at baseline, and were followed up at weeks 8 and 16 by using the Hamilton Rating Scale for Depression. RESULTS: Hierarchial logistic regression analyses demonstrated that response to maprotiline was significantly predicted by the cooperativeness score at the 8-week outcome assessment, and by the self-directedness score at the 16-week outcome assessment, after controlling the possible effects of clinical variables on the response. There was no evidence that either temperament dimensions or their 2-way interactions significantly predicted the response. LIMITATIONS: Large replication studies with other antidepressants are needed for generalizing the results in this study. CONCLUSIONS: The results in this study regarding temperament dimensions seem consistent with findings in previous studies, which are, as a whole, inconsistent with each other. It is suggested that character dimensions (particularly cooperativeness and self-directedness), rather than temperament dimensions, may be important predictors of response to antidepressants. Antidepressants may differ in the personality configurations that predict optimal responses.

Gene transfer to the rat biliary tract with the HVJ-cationic liposome method.

BACKGROUND/AIMS: The ability to transfer foreign genes into the biliary tract would be useful for the treatment of biliary tract diseases, including cancer, cystic fibrosis and other genetic diseases. To introduce a foreign gene precisely into the rat biliary epithelial cells, we developed a new technique, inserting a polyethylene catheter into the common bile duct through the papilla of Vater by use of a fusigenic cationic liposome with hemagglutinating virus of Japan (HVJ-cationic liposome). METHODS: Transfection efficiency was estimated with the use of FITC-oligonucleotides (FITC-ODNs) and cDNA of beta-galactosidase (pCAG-lacZ). RESULTS: FITC-ODNs encapsulated in HVJ-cationic liposome were effectively transfected into cell nuclei of human cholangiocellular carcinoma in vitro after a 30-min incubation as compared with the simple application of naked FITC-ODNs. After in vivo injection of FITC-ODNs using the HVJ-cationic liposome method through the papilla of Vater, fluorescence accumulation was observed only in the epithelial cells of the biliary tract, but not in the parenchymal cells of the liver. Beta-galactosidase expression was observed in the biliary epithelial cells 3 days after the transfection of pCAG-lacZ and was also detected at 14 days, but not at 28 days, without obvious cytotoxicity. CONCLUSIONS: HVJ-cationic liposome-mediated gene transfer to the biliary tract via the papilla of Vater is a minimally-invasive and an effective gene-delivery method for site-specific targeting to the epithelial cells of the biliary tract, which could be applied to the treatment of human biliary tract diseases.

The integrity of the disulfide bond in a cyclic somatostatin analog during 99mTc complexation reactions.

Recent development of a variety of thiol-free chelating agents has facilitated the design of 99mTc-labeled somatostatin analogs suitable for receptor imaging of somatostatin-positive tumors. However, it remains ambiguous whether the disulfide bonds in cyclic peptides are stable during 99mTc complexation reactions, and contradictory results have been reported regarding the integrity of disulfide bonds in cyclic somatostatin analogs. To estimate the stability of the disulfide bond in a synthetic somatostatin analog at low peptide concentrations, [125I]I-RC-160, in which radioiodine was incorporated into the 3-Tyr residue, was synthesized and the integrity of the disulfide bond of the peptide was investigated in the presence of reducing agents such as ascorbic acid, dithionite, and stannous ions. The disulfide bond in [125I]I-RC-160 remained stable in the presence of ascorbic acid in boiling water. The disulfide bond was also stable when treated with stannous ions at concentrations sufficient to reduce 99mTc for complexation with a thiol-free chelating agent, bis(hydroxamamide) analog when the 99mTc complexation reaction was performed at room temperature. However, the disulfide bond of [125I]I-RC-160 was slightly cleaved in the presence of a small amount of stannous ions when the reaction was performed in boiling water. Treatment of [125I]I-RC-160 with dithionite in boiling water markedly reduced the disulfide bond of the parental peptide. These findings indicated that synthetic somatostatin analogs may be labeled with 99mTc with stannous ions as the reducing agent without impairing their structure after conjugation of thiol-free chelating agents that provide 99mTc chelates under mild reaction conditions.

Confirmatory factor analysis of the Parental Bonding Instrument in a Japanese population.

BACKGROUND: There is controversy surrounding the factor structure of the Parental Bonding Instrument (PBI), a widely used instrument for assessing perceived parental rearing behaviours. Recent studies have proposed five different factor structures, including Parker et al.'s original two-factor model. METHODS: Four hundred and eighteen employed Japanese adults filled out the PBI. Maximum likelihood confirmatory factor analyses were performed to compare the five different factor structures in terms of model-fit. RESULTS: Parker's original two-factor structure fitted the data poorly. In general, three-factor structures showed better fit. Among the three-factor structures, Murphy's model and Kendler's model were superior (the adjusted goodness-of-fit index > 0.8), with the latter providing the best fit to the data (the goodness-of-fit index > 0.9). When considering invariance of factor structure across gender subgroups and across age subgroups, only Kendler's model was acceptable. CONCLUSIONS: Parker's two-factor structure of the PBI may not be appropriate for assessing perceived parental rearing behaviours in a Japanese population. Three-factor structures, in particular Murphy's model and Kendler's model, are preferable. Kendler's model provided the best fit to the data and was relatively invariant across the subgroups in this study. Thus, Kendler's model might prove to be very important for obtaining a factor structure invariant across different cultures.

The association between the high interpersonal sensitivity type of personality and a lifetime history of depression in a sample of employed Japanese adults.

BACKGROUND: Although the 'high interpersonal sensitivity' type of personality has repeatedly been shown to be related to depression by case-control studies, no studies have confirmed whether this association also exists in a non-clinical sample. METHODS: Scores on the Interpersonal Sensitivity Measure (IPSM) were compared between employed Japanese adults with and without a lifetime diagnosis of major depressive disorder. The diagnosis was provided by the Inventory to Diagnose Depression, Lifetime version. A multiple logistic regression analysis estimated the odds ratios for having a lifetime diagnosis of depression. RESULTS: The scores on the IPSM were higher in the subjects with a lifetime history of depression than those without a lifetime history of depression. On the five subscales of the IPSM, the subjects with a lifetime history of depression showed higher scores on 'interpersonal awareness', 'need for approval', and 'separation anxiety' than those without a lifetime history of depression. The multiple logistic regression analysis showed that the subjects with the high interpersonal sensitivity type of personality had an increased risk for experiencing lifetime depression. CONCLUSIONS: The results suggest that high interpersonal sensitivity is a risk factor for depression even in a non-clinical sample from non-Western culture.

Pertussis toxin-sensitive and insensitive intracellular signalling pathways in undifferentiated 3T3-L1 cells stimulated by insulin converge with phosphatidylinositol 3-kinase upstream of the Ras mitogen-activated protein kinase cascade.

We have previously reported that pertussis toxin (PTX)-sensitive GTP binding protein (G-protein) and phosphatidylinositol 3-kinase (PI 3-K) are involved in adipocyte differentiation of 3T3-L1 cells induced by insulin/dexamethasone/methylisobutyl xanthine. The aim of this study was to examine the effect of PTX on the tyrosine kinase cascade stimulated by insulin acting through insulin-like growth factor-I (IGF-I) receptors in undifferentiated 3T3-L1 cells. A high level of mitogen-activated protein kinase (MAPK) activation was sustained for up to 4 h after insulin treatment, and mobility shifted and tyrosine phosphorylated MAPK was also detected. MAPK kinase activity measured by the incorporation of 32P into kinase-negative recombinant MAPK was enhanced by insulin treatment. We previously discovered that insulin activates Ras and that this is mediated by wortmannin-sensitive PI 3-K. Tyrosine-phosphorylation of IRS-1 and Shc also occurred in response to insulin. Subsequently, we investigated the effects of PTX on the activation of these proteins by insulin. Interestingly, treating 3T3-L1 cells with PTX attenuates the activation by insulin of both the Ras-MAPK cascade and PI 3-K. In contrast, neither tyrosine-phosphorylation of IRS-1 and Shc nor the interaction between IRS-1 and PI 3-K is sensitive to PTX. However, activation of the Ras-MAPK cascade and tyrosine-phosphorylation of Shc by epidermal growth factor are insensitive to PTX. These results indicate that there is another pathway which regulates PI 3-K and Ras-MAPK, independent of the pathway mediated by IGF-I receptor kinase. These findings suggest that in 3T3-L1 fibroblasts, PTX-sensitive G-proteins cross-talk with the Ras-MAPK pathway via PI 3-K by insulin acting via IGF-I receptors.

Reliability of the 5-min speech sample for assessing expressed emotion in Japanese patients.

Expressed emotion (EE) has been shown in various countries to be a good predictor of the clinical course of a patient's mental illness. Because the traditional EE interview requires considerable time and effort, this study examined the reliability of a method called the five-minute speech sample (FMSS) for assessing EE. The samples of 65 subjects were rated by the FMSS-EE coding system, and the interrater reliability among four authorized raters was investigated. Of these 65 samples, 10 (15%) were rated as high-EE (high critical, 6%; high emotional over-involvement (EOI), 9%), and 19 (29%) were rated as borderline (b-)-high-EE (b-critical, 15%; b-EOI, 14%). The intraclass correlation coefficient (ICC) was 0.91 for the overall category, 0.74 for criticism, 0.85 for EOI, 0.63 for b-critical and 0.54 for b-EOI. The FMSS was shown to be reliable for the assessment of EE, even outside of Western countries. However, the lower agreement in the subcategories of EOI and b-critical has to be considered as a limitation of this brief method.

Caspase activation accompanying cytochrome c release from mitochondria is possibly involved in nitric oxide-induced neuronal apoptosis in SH-SY5Y cells.

It is well known that caspases are produced as proforms, which are proteolytically cleaved and activated during apoptosis or programmed cell death. We report here that caspases are activated during apoptosis by treatment with NOC18, a nitric oxide (NO) donor. Our present experiments have examined the way in which NO induces neuronal cell death, using a new type of NO donor that spontaneously releases only NO without enzymatic metabolism. NOC18 induced apoptosis in human neuroblastoma SH-SY5Y cells in a concentration- and time-dependent manner as estimated by DNA fragmentation assay, FACScan analysis, and nuclear morphology. Oxyhemoglobin, an NO trapper, suppressed NOC18-triggered DNA fragmentation, indicating that NO from NOC18 is a real activator in this study. Upon the induction of apoptosis, an increase in caspase-3-like protease activity, but not caspase-1, was observed. Procaspase-2 protein, an inactive form of caspase-2, decreased dramatically. In addition, NOC18 also resulted in poly (ADP-ribose) polymerase (PARP) cleavage, yielding an 85-kDa fragment typical of caspase activity. Oxyhemoglobin blocked the decrease of procaspase-2 and the cleavage of PARP by NOC18 in a concentration-dependent manner. Moreover, NO elicited the release of cytochrome c into the cytosol during apoptosis. These results suggest that both stimulation of caspase activity and cytochrome c release are partly involved in NO-induced neuronal apoptosis.

Personality disorder comorbidity in early-onset versus late-onset major depression in Japan.

This study explored the comorbidity of DSM-III-R personality disorders in early-onset versus late-onset major depression in Japan. The subjects were 117 consecutive outpatients with major depression, with 26 classified as having an early onset (first depressive episode at age 22 or earlier) and 91 classified as having a late onset (first depressive episode at age 23 or later). Personality disorders were assessed using the Structured Clinical Interview for DSM-III-R Personality Disorders after a 2-month antidepressant treatment. The results indicated that early-onset major depression was characterized by greater personality disorder comorbidity than late-onset major depression in Japan. Subjects with any one cluster A or B personality disorder were more prevalent in the early-onset group. In terms of each personality disorder, histrionic, narcissistic, and borderline patients were more prevalent, and the number of criteria met for schizotypal and cluster B personality disorders was significantly larger in early-onset major depression after corrections for age and gender. The results suggested that the higher prevalence of personality pathologies in early-onset major depression may reflect a higher likelihood to convert into bipolar disorders or a stronger impact of having experienced depressive episodes in young individuals. The possibility that the predisposing personality pathology may be different in early-onset and late-onset major depression is also discussed.

Factor analysis of the EMBU scale in a large sample of Japanese volunteers.

OBJECTIVE: The EMBU (Egna Minnen av Barndoms Uppfostran; (one's memories of upbringing') is a convenient and reliable instrument for the assessment of parental attitudes. The aim of the present study was to investigate the extent to which the factor structure of the EMBU, obtained in previous investigations, could be retrieved in a large Japanese sample. METHOD: The EMBU scale was administered to 1320 healthy Japanese volunteers. Both exploratory and confirmatory factor analyses were performed. RESULTS: The first factor in the analysis, accounting for 9.9% (father) and 10.6% (mother) of the variance, consisted of rejection items. The second factor, accounting for 9.1% (father) and 8.6% (mother) of the variance, contained items relating to emotional warmth. The third factor appeared to represent overprotection, and accounted for 7.8% (father) and 7.8% (mother) of the variance. The fourth factor, which accounted for 3.7% (father) and 3.7% (mother) of the variance, included items classified under favouring subjects. Confirmatory factor analysis revealed that this four-factor structure fitted our data very well for both the father and the mother. The results of factor analysis for four subscales showed three major factors for the EMBU. CONCLUSION: The results of this study confirmed that the EMBU yielded a factor structure in Japan similar to that found in European countries. The EMBU is useful for comparison of parenting attitudes in different societies or countries.

Characteristics of perceived parenting styles in Japan using the EMBU scale.

OBJECTIVE: The EMBU (Egna Minnen av Barndoms Uppfostran) is a self-report questionnaire for the assessment of one's memory of parental rearing experiences. We are interested in using this scale to determine the characteristics of perceived parenting styles in Japan. METHOD: The study subjects consisted of 1320 healthy Japanese volunteers, comprising 687 males (52%) and 633 females (48%). We investigated the relationship between demographics and the EMBU scale. RESULTS: ANCOVA revealed that the subject's gender had a significant effect on paternal rejection scores (male > female), and both gender and birth-order position had significant effects on emotional warmth scores for both parents (female > male, and only-child > middle or last-born child). Birth-order position had significant effects on maternal over-protection, with the highest score being that of only children, and on the aspect of favouritism (favouring subjects), scores for both parents were highest from the last-born children. Rejection scores for the mother were significantly higher than those for the father from female subjects. Among both male and female subjects, emotional warmth scores and overprotection scores for the mother were significantly higher than those for the father. Among male subjects, scores for the mother on favouritism of the subject were significantly higher than those for the father. On the other hand, among female subjects, scores for the father on favouritism of the subject were higher than scores for the mother. CONCLUSION: Our results suggest that parenting styles have significant interrelationships with the gender and birth-order position of the subject.
