Immunohistochemical alpha- and beta-catenin and E-cadherin expression and their clinicopathological significance in human lung adenocarcinoma.

The E-cadherin/catenin complex (alpha-catenin, beta-catenin, and E-cadherin) plays a crucial role in cell-cell adhesion and tissue remodeling, and abnormalities in these molecules have been suggested to participate in the proliferation and invasive and metastatic potentials of several human carcinomas. However, in human lung adenocarcinomas, its importance has not yet been sufficiently investigated. We immunohistochemically examined the expressions of E-cadherin/catenin complex in 35 primary lung adenocarinomas, and evaluated their expressions in a semiquantitative manner. Correlations between these expression levels, MIB-1 and nuclear p53 indices, and clinicopathological factors were analyzed by subdividing the cases into high- and low-expression groups for each protein. The reduction in membranous E-cadherin/catenin complex expression correlated significantly with low-grade histological differentiation and with high MIB-1 index. Survival analyses were also performed to clarify which factors potentially affected the prognosis of lung adenocarcinoma patients. The low expression of beta-catenin and the high MIB-1 index had a significantly unfavorable influence on the patients' survival. Moreover, the immunohistochemical expression of beta-catenin by cancer cells and MIB-1 index are considered useful prognostic factors for lung adenocarcinoma.

Interleukin-10 expression is positively correlated with oxidized LDL deposition and inversely with T-lymphocyte infiltration in atherosclerotic intimas of human coronary arteries.

The inflammatory balance modulated by pro- and anti-inflammatory cytokines in atherosclerotic lesions is still unclear. The purpose of this study was to investigate the immunohistochemical localization of interleukin-10 (IL-10) and the topographical correlation between IL-10-positive cells and the other inflammatory cells in human coronary arteries. Coronary arteries (242 sections) were obtained from 43 Japanese patients (mean age: 72+/-14 years) at autopsy, and the intimal changes were classified according to the classification of the American Heart Association. The immunohistochemical distributions of IL-10, oxidized low-density lipoprotein (oxLDL), macrophages, and lymphocytes were examined morphometrically. We compared the ratios of IL-10-positive cells/macrophages and T-lymphocyte number among the shoulder and in other areas of type IV lesions and in atherosclerotic lesion types. IL-10 was expressed mainly by macrophages, and the positive cell number increased as the lesions became advanced (p<0.0001). The number of IL-10-positive cells was positively correlated with that of oxLDL-positive cells, and inversely with infiltrating T-lymphocytes (p<0.01). IL-10 expression in type IV-plaque shoulder was significantly lower than that in fibrous cap and the deeper portion under necrotic core (p<0.01). These findings suggest that IL-10 expression, seen mainly in macrophages, was possibly upregulated with oxLDL, and was inversely correlated with T-lymphocytic function in atherosclerotic coronary intimas.

A decrease in AFP level related to administration of interferon in patients with chronic hepatitis C and a high level of AFP.

It is known that there is a very high incidence of hepatocellular carcinoma (HCC) among patients with type C chronic hepatitis and cirrhosis, and alpha -fetoprotein (AFP) has been widely used as a diagnostic marker for HCC. However, there are some patients showing continuous high AFP values but no evidence of HCC, and some studies have defined such patients as a high-risk group for HCC. In vitro study has shown that interferon (IFN) inhibits cell proliferation and enhances apoptosis as well as specific cytotoxic T lymphocytes against HCC, resulting in direct anticancer actions. In this study, we investigated the effect of IFN on AFP changes in chronic hepatitis C patients. Of 40 patients with chronic hepatitis C in whom diagnostic imaging confirmed the absence of HCC, 24 patients showed high pretreatment AFP values (high AFP group: AFP level > 10 ng/dl; mean +/- SD, 46.3 +/- 41.5 ng/dl) and 16 showed low pretreatment AFP values (low AFP group: pretreatment AFP level < or = 10 ng/dl; mean +/- SD, 5.3 +/- 2.2 ng/dl). Pretreatment clinical parameters were statistically evaluated in relation to the AFP value. In the high AFP group, the platelet count, albumin level, and prothrombin (%) were significantly lower (P = 0.047, P = 0.0002, and P = 0.044, respectively), suggesting that AFP value increases with advancing liver disease. Subsequently 27 patients were administered IFN (IFN group), and the remaining 13 patients were administered Stronger Neo-minophagen C (SNMC), a glycyrrhizin preparation (SNMC group), as a control group receiving liver-protective therapy. Alanine aminotransferase was reduced in both the IFN and the SNMC group (mean, 132.56 to 60.07 mg/ml [P < 0001] and 147.85 to 56.23 mg/ml [P = 0.0240], respectively). AFP was significantly reduced in the IFN group (mean, 30.03 to 12.65 ng/ml; P = 0.0034), but there was no significant change in AFP in the SNMC group (mean, 29.70 to 39.17 ng/ml). AFP is useful for diagnosing HCC; however, some patients show a persistently high AFP level in the absence of HCC, and these patients have been described as a high-risk group for HCC. In this study, we found that IFN therapy but not SNMC universally reduced the AFP baseline. Since AFP is a significant predictor for HCC, therapeutic strategies for hepatitis C, e.g., long-term low-dose IFN treatment, may reduce hepatocarcinogenesis.

[Pathological characteristics of diabetic macro-angiopathy].

The pathological features of coronary diabetic macro-angiopathy were characterized by the acceleration of atherosclerotic lesions. Among the Hisayama cohort study subjected for participants in the screening examination in 1988, the coronary atherosclerotic grade, pathologically estimated on luminal stenosis and/or incidence of advanced lesions of coronary arteries, was significantly correlated with serum HbA1c, levels. These findings suggest that the impaired glucose metabolism is a significant risk factor for coronary atherosclerosis in Japan. The clinico-pathological survey of risk factors for atherosclerosis in the general Japanese population would be very important in not only the further clarification of Japanese atherogenesis but also the exploration and development of novel diagnostic and therapeutic strategies, and preventive guidelines for atherosclerosis-related cardiovascular diseases in Japan nowadays under the remarkable changes of life-style.

Angiogenesis and lymphangiogenesis and expression of lymphangiogenic factors in the atherosclerotic intima of human coronary arteries.

Little information regarding the development of lymphangiogenesis in coronary atherosclerosis is available. We immunohistochemically investigated the correlation among intimal neovascularization (CD34 for angiogenesis and lymphatic vessel endothelial hyaluronan receptor-1 [LYVE-1] and podoplanin for lymphangiogenesis), the expression of lymphangiogenic factors (vascular endothelial growth factor [VEGF]-C and VEGF-D), and the progression of atherosclerosis using 169 sections of human coronary arteries from 23 autopsy cases. The more the atherosclerosis advanced, the more often the neointimas contained newly formed blood vessels ( P < .0001). Vascular endothelial growth factor-C was expressed mostly in foamy macrophages and in some smooth muscle cells, whereas VEGF-D was abundantly expressed in both. The number of VEGF-C-expressing cells, but not that of VEGF-D-expressing cells, was increased as the lesion advanced and the number of intimal blood vessels increased ( P < .01). Lymphatic vessels were rare in the atherosclerotic intima (LYVE-1 vs CD34 = 13 vs 3955 vessels) compared with the number seen in the adventitia (LYVE-1 vs CD34 = 360 vs 6921 vessels). The current study suggests that VEGF-C, but not VEGF-D, may contribute to plaque progression and be a regulator for angiogenesis rather than lymphangiogenesis in coronary atherosclerotic intimas. Imbalance of angiogenesis and lymphangiogenesis may be a factor contributing to sustained inflammatory reaction during human coronary atherogenesis.

Effects of estradiol administration on feto-placental growth in rat.

BACKGROUND: To clarify the effect of estradiol benzoate on placental structure and its consequences for fetal survival and fetoplacental growth. STUDY DESIGN: Estradiol benzoate (0, 0.1, 1, 10, 100 microg/day) was infused intraperitoneally into pregnant Wistar rats from 12 to 19 days' gestation. Survival rate, weight of pups and placentas at 20 days' gestation, and plasma levels of estrogen and progesterone were measured. Pathological changes in the placenta were also examined. RESULTS: Estradiol benzoate reduced fetal survival (1 microg/day: 100%, 10 microg/day: 70%, 100 microg/day: 14.6%) and the weights of the pups and placentas in a dose-dependent manner. Maternal estradiol concentration was raised 23-fold with 100microg/day of estradiol benzoate. Trophoblast degeneration, including apoptosis and destruction of placental labyrinth was induced but the structures of the maternal kidney and liver were not affected. CONCLUSIONS: In pregnant rats, estradiol benzoate causes fetal mortality at a pharmacological dose (more than 10 microg/day) and fetoplacental growth retardation via trophoblastic degeneration and destruction of the placental labyrinth even at a physiological dose (1 microg/day).

Clinicopathologic differences between 22 cases of CD56-negative and CD56-positive subcutaneous panniculitis-like lymphoma in Japan.

CD56 is an important marker for prospecting clinicopathologic features of cytotoxic T-cell and natural killer (NK)/T-cell lymphomas. We examined 22 cases of subcutaneous panniculitis-like lymphoma and classified these into CD56-positive and CD56-negative groups. The 11 CD56-negative cases were mainly in the younger age group and had systemic subcutaneous nodules without ulceration. They exhibited subcutaneous invasion by medium-sized lymphoma cells, scattered erythrophagocytosis, patchy necrosis, and little tumor invasion in the superficial dermis. Their lymphoma cells had characteristics of CD3 epsilon-, CD8-, TcR beta F1-, T-cell intracellular antigen (TIA)1-, and granenzyme B-positive cytotoxic T cells and were negative for apoptosis-promoting proteins CD95 (Fas), Bax, CPP32 (caspase 3), and p53 (DO7). Ten patients were alive despite clinical signs of hemophagocytic syndrome and relapses in 7 cases. The 11 CD56-positive cases had systemic ulcerative skin tumors composed of pleomorphic lymphoma cells with massive necrosis and little erythrophagocytosis involving the subcutis and also often the whole dermis. Their tumor cells were positive for CD3 epsilon, TIA1, granenzyme B, CD95, CD95L (Fas ligand), Bax, and CPP32. Three cases were of the TcR beta F1-positive phenotype, 1 was of the TcR gamma/delta-positive T-cell phenotype, and 6 were of the TcR beta F1- and TcR gamma/delta-negative NK/T-cell phenotype. Six cases were p53 (DO7) positive. Seven cases had complications of liver dysfunction and cytopenia, and 8 died of disease. One CD56-negative case and 3 CD56-positive cases had nuclear signals of Epstein-Barr virus-encoded RNA in their lymphoma cells. The 2 groups had significantly (P <0.01) different prognoses by Kaplan-Meier and log-rank methods. Patients with CD56-negative and CD56-positive groups had statistically different clinicopathologic, immunohistologic, and functional findings and prognoses.

Clinicopathologic analysis of 22 cases of subcutaneous panniculitis-like CD56- or CD56+ lymphoma and review of 44 other reported cases.

In 22 histologic cases of subcutaneous panniculitis-like lymphoma, we studied the clinicopathologic differences between CD56- and CD56+ cases (11 each). CD56- cases had skin ulcers (1 [9%]); tumor invasion in the superficial dermis (1 [9%]); erythrophagocytosis (10 [91%]); and medium-sized (11 [100%]), CD8+ (10 [91%]), T-cell receptor (TcR)betaF1+ (10 [91%]), and CD95 (Fas)- tumor cells. CD56+ cases had skin ulcers (9 [82%]); tumor invasion in the superficial dermis (8 [73%]); erythrophagocytosis (1 [9%]); and pleomorphic large (10 [91%]), CD8+ (2/10 [20%]), TcRbetaF1 + (3/10 [30%]), and CD95 (Fas)+ (7/10 [70%]) tumor cells. These 7 factors were significantly different between groups (P < .01). Median survival rates were 96 and 12 months for the CD56- and CD56+ groups, respectively. Age younger than 40 years, no skin ulcers, no tumor invasion in the superficial dermis, and CD8+, TcRbetaF1 +, CD95 (Fas)-, and CD56- tumor cells were significantly better prognostic factors (P < .01). The CD56- and CD56+ groups showed different tumor cell characteristics, clinicopathologic findings, and prognosis. In the CD56+ group, 1 was gamma/delta T-cell phenotype, 3 were alpha/beta T-cell, and 6 were TcRbetaF1- and gamma/delta- NK/T-cell, and 3 NK/T-cell cases had nuclear signals of Epstein-Barr virus-encoded RNA. Cases of CD56+ T- and NK/T-cell lymphoma had similar clinicopathologic findings and prognosis.

Long-term treatment with a Rho-kinase inhibitor improves monocrotaline-induced fatal pulmonary hypertension in rats.

Primary pulmonary hypertension is a fatal disease characterized by endothelial dysfunction, hypercontraction and proliferation of vascular smooth muscle cells (VSMCs), and migration of inflammatory cells, for which no satisfactory treatment has yet been developed. We have recently demonstrated that intracellular signaling pathway mediated by Rho-kinase, an effector of the small GTPase Rho, is involved in the pathogenesis of arteriosclerosis. In the present study, we examined whether the Rho-kinase-mediated pathway is also involved in the pathogenesis of fatal pulmonary hypertension in rats. Animals received a subcutaneous injection of monocrotaline, which resulted in the development of severe pulmonary hypertension, right ventricular hypertrophy, and pulmonary vascular lesions in 3 weeks associated with subsequent high mortality rate. The long-term blockade of Rho-kinase with fasudil, which is metabolized to a specific Rho-kinase inhibitor hydroxyfasudil after oral administration, markedly improved survival when started concomitantly with monocrotaline and even when started after development of pulmonary hypertension. The fasudil treatment improved pulmonary hypertension, right ventricular hypertrophy, and pulmonary vascular lesions with suppression of VSMC proliferation and macrophage infiltration, enhanced VSMC apoptosis, and amelioration of endothelial dysfunction and VSMC hypercontraction. These results indicate that Rho-kinase-mediated pathway is substantially involved in the pathogenesis of pulmonary hypertension, suggesting that the molecule could be a novel therapeutic target for the fatal disorder.

Prognostic significance of the F-box protein Skp2 expression in diffuse large B-cell lymphoma.

The F-box protein Skp2 positively regulates the G1-S transition by promoting degradation of the cyclin-dependent kinase inhibitor p27(kip1) (p27). Recent evidence has suggested an oncogenic role of Skp2 in not only carcinogenesis but also lymphomagenesis. In this study, we performed immunohistochemical analysis on the cell-cycle-associated proteins, Skp2, p27, and Ki-67, in 27 patients with de novo diffuse large B-cell lymphoma (DLBCL), evaluating the correlation between the clinical characteristics and expression levels of these proteins. The patients were classified into two groups according to the positivity for Skp2 expression: a high Skp2 expression group (>60% positive for Skp2 in lymphoma cells) and a low Skp2 expression group (< or = 60%). A high level of Skp2 expression significantly correlated with advanced clinical stage (P = 0.029), although the increase did not correlate with age, gender, LDH levels, presence of extranodal disease, or performance status and resulted in no correlation with the International Prognostic Index-based risk grading. However, it was noteworthy that the high Skp2 expression group demonstrated a significantly worse prognosis than the low Skp2 expression group (P = 0.0007). The expression level of Skp2 correlated with that of Ki-67 but not necessarily with that of p27. The p27 expression level did not correlate patients' prognosis. Taken together, it was suggested that Skp2 was a valuable and independent marker predicting the outcome in DLBCL.

Immune and non-immune factors in cryopreserved tissues.

BACKGROUND: Although cryopreserved tissues are used clinically, the effects of cryopreservation on antigenicity leading to immune and non-immune responses are not well known. METHODS: We investigated the change of inflammatory effects of cryopreserved tissue by using spleen and aortic allografts from Class I antigen-disparate B6.C-H-2(bm1) (bm1; K(bm1), IA(b), D(b)), Class II antigen-disparate B6.C-H-2(bm12) (bm12; K(b), IA(bm12), D(b)) and Class I and Class II antigen-disparate (bm1 x bm12)F1 (K(bm1 x b), IA(b x bm12), D(b)) mice against C57BL/6 Cr Slc (B6; H-2(b)) mice. Cryopreservation was done in a programmed freezer and cryopreserved tissues were kept in the vapor phase of liquid nitrogen for 2 weeks and thawed at room temperature. RESULTS: Cryopreserved B6 spleen cells expressed almost the same levels of Class I (K(b) and D(b)) and Class II (IA(b)) antigens as observed in fresh B6 spleen cells. Cryopreserved bm1 and bm12 spleen cells had the same stimulator activities in mixed-lymphocyte reaction (MLR) and cytotoxic T-lymphocyte (CTL) assays compared with fresh bm1 and bm12 spleen cells, respectively. To elucidate the effects of cryopreserved tissues on immune response of recipients, descending aortas of (bm1 x bm12)F1 mice were implanted into the right common carotid artery of B6 (H-2(b)) mice with the cuff technique and the reactivities of recipient B6 mice against Class I antigen-disparate bm1 antigens and Class II antigen-disparate bm12 antigens were examined 4 weeks after implantation. In both MLR and CTL assays against bm1 or bm12 antigens, anti-donor reactivities were augmented and there was no significant difference between B6 mice grafted with fresh aortic allografts and those grafted with cryopreserved ones. Histologic analysis showed that mild infiltration of mononuclear cells into the adventitia was observed in both fresh and cryopreserved aortic allografts. The fibrous change was observed more strongly in cryopreserved aortic allografts compared with fresh aortic allografts. CONCLUSIONS: Cryopreservation has no effect on eliciting immune responses to Class I or Class II alloantigens, but has some effect on promoting fibrous change.

Portal vein invasion and intrahepatic micrometastasis in small hepatocellular carcinoma by gross type.

Background/AIMS: Recurrence due to clinically undetectable intrahepatic metastasis and portal vein invasion of HCC cells is not 'uncommon' even in small HCCs. The present study investigated the relationship between these factors and macroscopic types of HCC. METHODS: Surgically resected 209 cases of small HCC less than 3 cm in diameter were examined. Macroscopically, 209 cases were divided into 'vaguely nodular type', 'single nodular type', 'single nodular type with extranodular growth' and 'confluent multinodular type'. RESULTS: None of the vaguely nodular type had intrahepatic metastasis or portal vein invasion, and their diameter was significantly smaller than the other three types. 'Single nodular type with extranodular growth' and 'confluent multinodular type' show higher frequency of portal vein invasion and intrahepatic metastases than 'single nodular type'. Among 149 metastatic lesions, the distance was 10 mm or shorter in 118 (79.2%). CONCLUSIONS: It is important to precisely determine the gross type of small HCC by diagnostic imaging in order to predict portal vein invasion and micrometastasis. It is also important to ablate the tumor with enough surrounding tissue 1 cm in width at least to prevent the recurrence from those micrometastasis.

Plaque-stabilizing effect of pitavastatin in Watanabe heritable hyperlipidemic (WHHL) rabbits.

This study investigated the effect of pitavastatin, a 3-hydroxy-3-methylglutaryl coenzyme A ( HMG-CoA ) reductase inhibitor with strong cholesterol-lowering activity, on the composition of atherosclerotic plaque. Pitavastatin ( 0.5mg/kg ) was administered to Watanabe heritable hyperlipidemic ( WHHL ) rabbits for 16 weeks, with the result that plasma total cholesterol ( TC ), very low density lipoprotein ( VLDL )-C, intermediate density lipoprotein ( IDL )-C and low density lipoprotein ( LDL )-C decreased by 28.6, 60.0, 42.3 and 21.7%, respectively. In the aorta, pitavastatin reduced the area of the lesion by 38.6%. In the pitavastatin group, the macrophage-positive area in the aortic plaque was reduced by 39.4%, and the areas occupied by collagen and a-smooth muscle actin ( alpha-SMA )-positive area increased by 66.4 and 91.7%, respectively. In the aortic arch, pitavastatin increased the average thickness of alpha-SMA in the plaque by 96.7% and reduced the vulnerability index by 76.0%. Furthermore, pitavastatin reduced the positive areas of monocyte chemoattractant protein ( MCP )-1, matrix metalloproteinase ( MMP )-3 and MMP-9 by 39.1, 40.6 and 52.3%, respectively. These results indicated that pitavastatin had an excellent lipid-lowering effect in WHHL rabbits, suppressing the progression of atherosclerosis and stabilizing atherosclerotic plaque.

Distributions of diffuse intimal thickening in human arteries: preferential expression in atherosclerosis-prone arteries from an early age.

Diffuse intimal thickening (DIT) is a thickened intima present in human arteries before atherosclerosis develops and is considered to be related to atherogenesis. The purpose of this study was to clarify the systemic and age distributions of DIT. Coronary, cerebral, carotid, subclavian, iliac and abdominal organ arteries and the aorta were examined in 72 autopsy cases (aged 36 weeks of gestation to 30 years at death). DIT was found in the coronary arteries and aorta from 36 weeks of gestation and the first year of life, respectively. The intima/media (I/M) ratio of coronary arteries showed an age-dependent increase and was much greater than that of other muscular arteries, i.e., intracranial and extraparenchymal cerebral arteries and abdominal organ arteries. Aorta also demonstrated age-dependent as well as site-dependent increases of I/M ratio; the more distal the segments, the greater the ratio. Consequently, the abdominal aorta had the largest I/M ratio within the aorta. Other elastic arteries, i.e., carotid, subclavian and iliac arteries, showed trends similar to the distal portions of the aorta. Thus, DIT was strongly expressed from an early age in arteries that are considered to be prone to atherosclerosis. These findings suggest that the development of atherosclerosis depends at least partly on the degree of DIT.

Heart allograft tolerance without development of posttransplant cardiac allograft vasculopathy in chimerism-based, drug-induced tolerance.

BACKGROUND: Recently, we have described a drug (cyclophosphamide [CP] plus busulfan [BU])-induced skin allograft tolerance in mice that can regularly overcome fully H-2-mismatched barriers. Using this method, we have investigated whether or not this regimen can prolong the survival of heart allografts and inhibit the development of posttransplant cardiac allograft vasculopathy (CAV). METHODS: The components of the method are intravenous administration of 1 x 108 allogeneic spleen cells on day 0, intraperitoneal injection of 200 mg/kg of CP and 30 mg/kg of BU on day 2, and intravenous injection of T cell-depleted 1 x 107 allogeneic bone marrow cells from the same strain of mice on day 3. Heart grafting was performed on day 28. Chimerism in peripheral blood was followed by flow cytometric analysis, and histological analysis was performed at various times after grafting. RESULTS: In a fully major histocompatability complex (MHC)-mismatched combination of B10.D2 (H-2d, IE+)-->B10 (H-2b, IE-), stable, multilineage-mixed chimerism was observed permanently. B10.D2 heart grafts were accepted permanently in a donor-specific manner, and posttransplant CAV did not develop. CONCLUSIONS: These results demonstrated that the drug-induced tolerance recently established by us can regularly induce a long-lasting heart allograft tolerance without development of CAV.

Fibroblast growth factor-2 determines severity of joint disease in adjuvant-induced arthritis in rats.

Rheumatoid arthritis (RA), a systemic inflammatory disease of unknown etiology, mainly affects synovial joints. Although angiogenic growth factors, including fibroblast growth factor-2 (FGF-2) and vascular endothelial growth factor (VEGF), may play a critical role in the development and progression of RA joint disease, little information is now available regarding their exact role in initiation and/or progression of RA. In this study, we show that both polypeptides were up-regulated in the rat joint synovial tissue of an adjuvant-induced model of arthritis (AIA), as well as human subjects with RA. FGF-2 overexpression via Sendai virus-mediated gene transfer significantly worsened clinical symptoms and signs of rat AIA, including hind paw swelling and radiological bone destruction, as well as histological findings based on inflammatory reaction, synovial angiogenesis, pannus formation, and osteocartilaginous destruction, associated with up-regulation of endogenous VEGF. FGF-2 gene transfer to non-AIA joints was without effect. These findings suggested that FGF-2 modulated disease progression, but did not affect initiation. Reverse experiments using anti-FGF-2-neutralizing rabbit IgG attenuated clinical symptoms and histopathological abnormalities of AIA joints. To our knowledge, this is the first report indicating direct in vivo evidence of disease-modulatory effects of FGF-2 in AIA, as probably associated with endogenous VEGF function. FGF-2 may prove to be a possible therapeutic target to treat subjects with RA.
