Abstract
Giant cell tumor of bone (GCTB) is a rare osteolytic bone tumor consisting of mononuclear stromal cells, macrophages, and osteoclast-like giant cells. Although GCTB predominantly exhibits benign behavior, the tumor carries a significant risk of high local recurrence. Furthermore, GCTB can occasionally undergo malignant transformation and distal metastasis, making it potentially fatal. The standard treatment is complete surgical resection; nonetheless, an optimal treatment strategy for advanced GCTB remains unestablished, necessitating expanded preclinical research to identify appropriate therapeutic options. However, only one GCTB cell line is publicly available from a cell bank for research use worldwide. The present study reports the establishment of two novel cell lines, NCC-GCTB8-C1 and NCC-GCTB9-C1, derived from the primary tumor tissues of two patients with GCTB. Both cell lines maintained the hallmark mutation in the H3-3A gene, which is associated with tumor formation and development in GCTB. Characterization of these cell lines revealed their steady growth, spheroid-formation capability, and invasive traits. Potential therapeutic agents were identified via extensive drug screening of the two cell lines and seven previously established GCTB cell lines. Among the 214 antitumor agents tested, romidepsin, a histone deacetylase inhibitor, and mitoxantrone, a topoisomerase inhibitor, were identified as potential therapeutic agents against GCTB. Conclusively, the establishment of NCC-GCTB8-C1 and NCC-GCTB9-C1 provides novel and crucial resources that are expected to advance GCTB research and potentially revolutionize treatment strategies.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare mesenchymal tumor characterized by rearrangement of the ASPSCR1 and TFE3 genes and a histologically distinctive pseudoalveolar pattern. ASPS progresses slowly, but is prone to late metastasis. As ASPS is refractory to conventional chemotherapy, the only curative treatment is complete surgical resection. The prognosis of advanced and metastatic cases is poor, highlighting the need for preclinical research to develop appropriate treatment options. However, ASPS is extremely rare, accounting for < 1% of all soft tissue sarcomas, and only one patient-derived ASPS cell line is available from public cell banks worldwide for research. This study reports the establishment of a novel ASPS cell line derived from the primary tumor tissue of an ASPS patient, named NCC-ASPS2-C1. This cell line retains the ASPSCR1-TFE3 fusion gene, which is characteristic of ASPS. The characterization of this cell line revealed stable growth, spheroid formation, and invasive properties. By screening a drug library using NCC-ASPS2-C1, we identified several drugs that inhibited the proliferation of ASPS cells. In conclusion, the establishment of NCC-ASPS2-C1 provides a valuable resource for advancing ASPS research and developing novel treatments for this challenging disease.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is the most prevalent dermal sarcoma, characterized by the presence of the fusion of the collagen type I alpha 1 (COL1A1) gene with the platelet-derived growth factor beta chain (PDGFB) gene. Although PDGF receptor inhibitor imatinib mesylate was approved for the treating patients with unresectable or metastatic DFSP, disease progression was shown in 9.2% of the patients. Therefore, developing novel therapeutic strategies is crucial for improving the prognosis of DFSP. Patient-derived cell lines play a vital role in preclinical studies; however, only a limited number of DFSP cell lines are currently available in public cell banks. Here, we successfully established a novel DFSP cell line (NCC-DFSP5-C1) using surgically resected tumor tissue from a patient with DFSP. NCC-DFSP5-C1 cells were confirmed to carry the COL1A1-PDGFB translocation and maintain the same mutation as the original tumor tissue. They exhibited consistent growth, formed spheroids, and were invasive. By screening a drug library using NCC-DFSP5-C1 and four previously established DFSP cell lines, we identified anti-cancer drugs that inhibit DFSP cell proliferation. Our observations suggest that the NCC-DFSP5-C1 cell line holds promise as a valuable tool for conducting fundamental and preclinical studies for DFSP.

Abstract
Leiomyosarcoma (LMS) is an aggressive mesenchymal malignancy, which originates from the smooth muscle cells or from the precursor mesenchymal stem cells that potentially differentiate into smooth muscle cells. LMS is one of the most common sarcomas. LMS has genomic instability, reflecting complex and unbalanced karyotypes, and the cytogenetic and molecular changes in LMS are not consistent. The standard treatment of the primary LMS is complete resection, and the metastasis is often observed even after curative surgery. Patient-derived cancer models are a key bioresource to develop a novel therapy, and we aimed to establish and characterize a novel cell line for LMS. We established a cell line from tumor tissues of the patient with LMS and named it NCC-LMS3-C1. We maintained NCC-LMS3-C1 cells for 12 months and passed them more than 30 times. Genome-wide copy number analysis demonstrated that NCC-LMS3-C1 cells harbored genetic abnormalities. NCC-LMS3-C1 cells exhibited aggressive phenotypes such as continuous growth, spheroid formation, and invasion in the tissue culture condition, which may reflect the clinical behaviors of LMS. We performed a drug screening using NCC-LMS3-C1 cells and found that four anti-cancer agents, such as bortezomib, dasatinib, mitoxantrone, and romidepsin, had remarkable anti-proliferative effects on NCC-LMS3-C1 cells. We conclude that NCC-LMS3-C1 cells will be a useful resource for the study of LMS.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a superficial low-grade sarcoma, genetically characterized by a fusion gene in collagen type I α (COL1A1) gene and platelet-derived growth factor subunit β (PDGFB). DFSP is locally aggressive and does not typically metastasize. However, DFSP with fibrosarcomatous transformation, which occurs in 7-16% of DFSP cases, demonstrates a poor prognosis than classic DFSP with a higher local recurrence rate and metastatic potential. Although imatinib, a PDGF receptor inhibitor, is a potent therapeutic agent for classic DFSP, it is less effective for DFSP with fibrosarcomatous transformation. The development of definitive chemotherapies for DFSP with fibrosarcomatous transformation is required. Patient-derived tumor cell lines are indispensable tools for preclinical research to discover novel therapeutic agents. However, only seven cell lines were derived from DFSP, out of which only two were established from DFSP with fibrosarcomatous transformation. Hence, in the present study, we established a novel DFSP cell line, NCC-DFSP4-C1, from a surgically resected DFSP tumor specimen with fibrosarcomatous transformation. NCC-DFSP4-C1 harbored an identical COL1A1-PDGFB fusion gene as its donor tumor. NCC-DFSP4-C1 cells retained the morphology of their donor tumor and demonstrated constant proliferation, spheroid formation, and invasion capability in vitro. By screening a drug library, we found that bortezomib and romidepsin demonstrated the strongest suppressive effects on the proliferation of NCC-DFSP4-C1 cells. In conclusion, we report a novel cell line of DFSP with fibrosarcomatous transformation, and demonstrate its utility in the development of novel therapeutic agents for DFSP.

Abstract
Desmoid fibromatosis (DSM) is a rare, locally aggressive mesenchymal tumor genetically characterized by mutations in the CTNNB1 gene. A local control rate of up to 65‒80% for DSM is achieved with multiple modality treatments, including watchful monitoring, radiation therapy, chemotherapy, and surgery. However, several variables, such as age < 30 years, extremity tumor location, and tumor size of > 10 cm in diameter, are associated with poor local control rates in patients with DSM. The definitive treatments for DSM have not been established. Therefore, it is necessary to develop novel treatments for DSM. Moreover, although patient-derived tumor cell lines are potent tools for preclinical research, no DSM cell lines have been reported. Therefore, this study aimed to establish and characterize a novel DSM cell line for preclinical studies on DSM. Herein, we established the first cell line derived from a patient with DSM exhibiting poor prognostic factors (27-year-old male patient with a DSM tumor of > 10 cm in diameter located at the lower extremity) and named it NCC-DSM1-C1. NCC-DSM1-C1 cells had a T41A mutation in CTNNB1 and exhibited constant proliferation, spheroid formation, and invasion capability in vitro. Screening of antitumor agents in NCC-DSM1-C1 cells showed that bortezomib and romidepsin are effective against DSM. In conclusion, we report the first officially characterized DSM cell line derived from a patient with DSM exhibiting factors associated with poor prognosis. We believe that NCC-DSM1-C1 cell line is a useful tool for developing novel treatments for DSM.

Abstract
Teeth are exposed to various stimuli, including bacterial, thermal, and physical stimuli. Therefore, immune cells present in the normal dental pulp and the immune response to these stimuli have been studied. However, the relationship between systemic inflammation, such as that induced by viral infection, and changes occurring in dental pulp is not well known. This study aimed to investigate the immunological and hematological responses to systemic inflammation in dental pulp. Poly(I:C), a toll-like receptor 3 agonist, was injected into mice every two days to simulate a systemic inflammatory state in which type I interferon (IFN–I) was produced. The untreated normal state was defined as a steady state, and the states of acute and chronic inflammation were defined according to the period of administration. Changes in the abundance and dynamics of hematopoietic and immune cells in dental pulp, bone marrow and peripheral blood were quantitatively investigated in the steady state and under conditions of inflammation induced by IFN-l. We found that dental pulp in the steady state contained only a few hematopoietic cells, but a greater variety of immune cells than previously reported. B cells were also found in the steady state. An increase in multipotent progenitor cell levels was observed in the dental pulp during both acute and chronic inflammation. The increased multipotent progenitor cells in the dental pulp during acute inflammation tended to differentiate into the myeloid lineage. On the other hand, there was an influx of B cells into the dental pulp during chronic inflammation. These results revealed that a unique immune response is induced in the dental pulp by systemic inflammation, which would lead to a significant change in the perspective of dentists on the utility of dental pulp in the management of systemic diseases.

Abstract
Primary cultures of neonatal cardiac myocytes were used to determine both the identity of second messengers that are involved in vasopressin receptor-mediated effects on cardiac hypertrophy and the type of vasopressin receptor that is involved in vasopressin-induced cell growth. Neonatal rat myocytes were plated at a density of 1x10(6) cells per 60 mm dish and were incubated with serum-free medium for 7 days. Treatment of myocytes with vasopressin significantly increased the RNA-to-DNA ratio, by 18-25%, at culture days 4-6 and the protein-to-DNA ratio by 18-20% at culture days 5-7. Rates of protein synthesis were determined to assess their contribution to protein contents during myocyte growth. Vasopressin significantly accelerated rates of protein synthesis by 25% at culture day 6. Intracellular free Ca(2+) ([Ca(2+)](i)) was transiently increased after vasopressin exposure. After the peak increase in [Ca(2+)](i) at less than 30 s, there was a sustained increase for at least 5 min. The specific activity of protein kinase C in the particulate fraction was increased rapidly after exposure to vasopressin, and its activity remained higher for 30 min, returning to its control level within 60 min. The activity of protein kinase C in the cytosol was significantly decreased at all times after exposure to vasopressin. After vasopressin treatment, the content of c-fos mRNA was increased. The stimulatory effects of vasopressin on these parameters were significantly inhibited by vasopressin V(1A) receptor antagonist, OPC-21268, but not by vasopressin V(2) receptor antagonist, OPC-31260. These results suggest that vasopressin directly induces myocyte hypertrophic growth via the V(1A) receptor in neonatal rat heart cells.

Abstract
Angiotensin II activates p21ras, and mediates cardiac hypertrophic growth through the type 1 angiotensin II receptor in cardiac myocytes. An inhibitor of 3-hydroxy-3-methyglutaryl-coenzyme A (HMG-CoA) reductase has been shown to block the post-translational farnesylation of p21ras and inhibit protein synthesis in several cell types. Primary cultures of neonatal cardiac myocytes were used to determine whether HMG-CoA reductase inhibitors, lovastatin, simvastatin and pravastatin inhibit the angiotensin II-induced hypertrophic growth. Angiotensin II (10(-6) M) significantly increased protein-DNA ratio, RNA-DNA ratio, ratios of protein synthesis and mitogen-activated protein (MAP) kinase activity. Lipid-soluble HMG-CoA reductase inhibitors, lovastatin (10(-6) M) and simvastatin (10(-6) M) partially and significantly inhibited the angiotensin II-induced increases in these parameters, but a water-soluble HMG-CoA reductase inhibitor, pravastatin (10(-6) M) did not. Mevalonate (10(-4) M) overcame the inhibitory effects of lovastatin and simvastatin on angiotensin II-induced increases in these parameters. A selective protein kinase C inhibitor, calphostin C (10(-6) M) partially and significantly prevented angiotensin II-induced increases in these parameters, and treatment with both lovastatin and calphostin C inhibited completely. Angiotensin II increased p21ras activity and membrane association, and lovastatin inhibited them. These studies demonstrate that a lipid-soluble HMG-CoA reductase inhibitor, lovastatin, may prevent angiotensin II-induced cardiac hypertrophy, at least in part, through p21ras/MAP kinase pathway, which is linked to mevalonate metabolism.

Abstract
BACKGROUND Production of heat shock protein 70 (HSP70) in the heart is induced by hemodynamic stress, but its intracellular signal transduction system has not been elucidated well. OBJECTIVE To investigate the hypothesis that protein kinase A (PKA)-dependent and protein kinase C (PKC)dependent systems are involved in the pressure-induced expression of HSP70 mRNA in perfused adult rat heart METHODS Isolated tetrodotoxin-arrested Sprague-Dawley rat hearts were perfused as Langendorff preparations at a constant aortic pressure of 60 mmHg. Aortic pressure in rats of the pressure-overloaded group was elevated from 60 to 120 mmHg for 2-120 min. cAMP contents and rates of synthesis of protein were measured by radioimmunoassay and the incorporation of [14C]-phenylalanine into total heart protein, respectively. Expression of HSP70 mRNA was determined by Northern blot analysis. RESULTS Elevation of aortic pressure significantly increased cAMP content after 2 min of perfusion (by 41%), significantly increased rates of synthesis of protein during the second hour of perfusion (by 41%), and induced expression of HSP70 mRNA maximally after 60 min of perfusion (2.7-fold the control value). Exposure to glucagon, forskolin or 1 -methyl-3-isobutylxanthine mimicked increases in these parameters caused by elevation of aortic pressure. Administration of a selective PKA inhibitor, H-89, significantly prevented induction of increases in expression of HSP70 mRNA and rates of synthesis of protein by a high pressure overload and exposure to agents that increase cAMP content. Furthermore, administration of phorbol ester induced expression of HSP70 mRNA. Administration of a PKC inhibitor, calphostin C, significantly prevented induction of increases in expression of HSP70 mRNA by a pressure overload and by exposure to phorbol ester. CONCLUSIONS These results suggest that the pressure-induced induction of production of HSP70 is regulated both by PKA-dependent and by PKC-dependent systems during periods of active synthesis of protein in adult rat heart.

Abstract
It is not certain whether activation of the Ras/mitogen-activated protein (MAP) kinase pathway is involved in cardiac hypertrophy. 3-Hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, such as lovastatin, prevent farnesylation of the Ras protein, which is critical for Ras's membrane localization and function. Therefore, the present study was undertaken to investigate the role of the Ras pathway, which is linked to mevalonate metabolism, in the mechanism of stretch-induced myocyte hypertrophy. Myocytes isolated from 1- to 2-day-old rats were cultured at 4.1 x 10(6) cells per well in a deformable silicon dish and incubated with serum-free medium for 7 days. The cultures were stretched by 15% on culture day 4. Stretch increased the RNA/DNA ratio by 20% to 26% on culture days 5 and 6 and the protein/DNA ratio by 18% to 20% on culture days 6 and 7. Stretch accelerated rates of protein synthesis by 24% on culture day 6. Stretch increased protein kinase C (PKC) activity, MAP kinase activity, and c-fos mRNA expression. A selective PKC inhibitor, calphostin C (1 x 10(-6) M), prevented the stretch-induced increase in PKC activity, but lovastatin (7.5 x 10(-6) M) did not. Lovastatin as well as calphostin C partially but significantly inhibited the stretch-induced increases in MAP kinase activity, c-fos mRNA expression, and protein synthesis. Pretreatment with both lovastatin and calphostin C completely inhibited the increases in these variables caused by stretch. Lovastatin as well as calphostin C prevents stretch-induced cardiac hypertrophy. These results suggest that mechanical stretch may activate the Ras pathway, which is linked to mevalonate metabolism, in cultured neonatal rat heart cells.

Abstract
OBJECTIVES The aim was to determine whether proto-oncogene c-fos expression and acceleration of protein synthesis by acute pressure overload to the heart were coupled with a cAMP- and protein-kinase-A-dependent system in adult rat heart. METHODS Isolated adult rat hearts were perfused as Langendorff preparations at a constant aortic pressure of 60 mmHg. In the pressure-overloaded group, aortic pressure was raised from 60 to 120 mmHg for the time indicated. Agents that increase cAMP were added to the perfusate at an aortic pressure of 60 mmHg. Furthermore, a selective protein kinase A inhibitor (H-89) or a selective protein kinase C inhibitor (calphostin C) was administered before the elevation of aortic pressure or the addition of the agents. cAMP content or rates of protein synthesis were measured by RIA or the incorporation of [14C]phenylalanine into total heart protein, respectively. c-fos mRNA expression was determined by Northern blot analysis. RESULTS Elevation of aortic pressure in beating hearts and arrested hearts increased cAMP content at 2 min of perfusion by 36 and 41%, induced c-fos mRNA expression at 30-60 min of perfusion by 4.8- and 2.0-fold, and accelerated rates of protein synthesis during the 2nd hour of perfusion by 39 and 41% over control levels, respectively. Glucagon, forskolin or IBMX mimicked increases in these parameters by elevated aortic pressure. H-89 prevented these changes by elevated pressure overload or exposure to forskolin or IBMX in arrested hearts. On the other hand, calphostin C prevented the pressure-induced increases in c-fos expression and protein synthesis rates in arrested hearts. CONCLUSIONS These results suggest that c-fos expression induced by acute pressure overload may be coupled with increased cAMP content and protein kinase A activity in addition to increased protein kinase C activity in adult rat heart.

Abstract
Although it is well known that mechanical load to cardiac muscles causes cardiac hypertrophy, little is known about how mechanical load is transduced into the activation of intracellular signals which are linked to cell growth. We investigated whether the cardiac renin-angiotensin system was involved in stretch-induced hypertrophy of cultured neonatal rat heart myocytes. Myocytes were cultured with serum-free medium in a deformable silicon dish. Stretch of cardiac myocytes significantly increased the protein/DNA ratio at culture days 6 and 7, and the RNA/DNA ratio at culture days 4 and 5. Stretch significantly accelerated rates of protein synthesis by 15%. c-fos mRNA expression was significantly increased after stretch. The stimulatory effects of cell stretch on these parameters were significantly inhibited by the angiotensin converting enzyme inhibitor, captopril, or the type 1 angiotensin II receptor antagonist, losartan. The concentrations of angiotensin I and angiotensin II in culture media were significantly increased by stretch. Stretch did not change the angiotensin converting enzyme activity. These studies demonstrate that mechanical stretch activates the cardiac renin-angiotensin system in a autocrine and paracrine system which acts as an initial mediator of the stretch-induced hypertrophic growth.

Abstract
The present experiments were undertaken to clarify the difference of renal dopamine production from beta 1-selective beta-blocker with and without intrinsic sympathomimetic activity (ISA). Either beta-blocker with ISA, celiprolol (100 or 300 mg/kg/day; CEL-100 or CEL-300) or beta-blocker without ISA, atenolol (50 mg/kg/day; ATE-50) was administered to the SHR from 19 to 26 weeks. Degrees of lowering blood pressure in CEL-300 SHR and in ATE-50 SHR were similar, but decrease in heart rate was significantly less in CEL-300 SHR than in ATE-50 SHR. Urine output, which was significantly less in control SHR than in control WKY, was significantly greater in CEL-100 SHR and CEL-300 SHR, but not in ATE-50 SHR. Urinary excretions of noradrenaline (u-NA) and dopamine (u-DA) were significantly higher in control SHR than in control WKY and a comparable u-DA/u-NA ratio was found in these two groups. U-DA and the ratio of u-DA/u-NA were significantly elevated in CEL-100 SHR and CEL-300 SHR, but not in ATE-50 SHR. There was a significant positive correlation between u-DA/u-NA ratio and urine output and a significant negative correlation between the ratio of u-DA/u-NA and change of blood pressure in control SHR, CEL-100 SHR and CEL-300 SHR. These results suggest that an enhancement of renal dopamine production by ISA (beta 2 stimulation) of beta 1-selective beta-blocker may contribute, at least in part, to the antihypertensive effect of this drug.

Abstract
The purpose of the present study were to determine the contribution of Na+/H+ exchange to pressure overload-induced cardiac hypertrophy and to examine its potential interaction with cAMP-dependent signaling pathway. Isolated rat hearts were perfused as Langendorff preparations with aortic pressure of 60 mmHg. In pressure overload group, aortic pressure was increased to 120 mmHg. cAMP contents in the heart perfused at 2 min were examined by RIA. Rates of protein synthesis were examined by 14C-phenylalanine incorporation into myocardial protein during the second hour of perfusion. Expression of c-fos mRNA in the heart perfused at 1 hour was analyzed by Northern blotting. Elevation of aortic pressure from 60 mmHg to 120 mmHg in perfused rat hearts increased cAMP contents from 4.89 +/- 0.09 to 6.30 +/- 0.28 pmol/mg protein and accelerated rates of protein synthesis from 644 +/- 13 to 860 +/- 49 mmol Phe/g dry heart/hr. Expression of c-fos mRNA was induced by elevated aortic pressure. Amiloride, an inhibitor of Na+/H+ exchange, decreased rates of protein synthesis in a concentration-dependent manner (12.5, 25, 50, 100 microM) but did not change cAMP content (5.25 +/- 0.11 pmol/mg protein) or expression of c-fos mRNA. Furthermore, amiloride did not prevent the increases in cAMP (6.99 +/- 0.34 pmol/mg protein), protein synthesis rates (476 +/- 18 to 689 +/- 31 nmolPhe/g dry heart/hr) and expressions of c-fos mRNA that were induced by elevation of aortic pressure. These results indicate that amiloride, an inhibitor of Na+/H+ exchange system, while influencing rates of protein synthesis, does not play an important role in pressure overload-induced cardiac hypertrophy. The mechanism by which amiloride influences cardiac protein synthesis is independent of the cAMP-dependent mechanism by which pressure overload induces cardiac hypertrophy.

Abstract
We encountered a patient with spontaneous coronary artery dissection complicated by acute inferior myocardial infarction. A 58-year-old male was admitted to our hospital due to acute inferior myocardial infarction in 1979. Coronary angiography performed 4 weeks after the onset showed a double lumen divided by a linear intimal flap in the right coronary artery, suggesting coronary artery dissection, but no apparent occlusion. Subsequently, he had been medicated with nitrates without any recurrent infarction. In February, 1989, 10 years after the first examination, coronary angiography was again performed and showed that the dissection had remained unchanged. Acetylcholine infusion into the right coronary artery induced coronary spasm. The prognosis of this condition seems to be better than has been generally considered, particularly in patients such as ours in whom the involvement of coronary spasm in the development of coronary artery dissection and myocardial infarction is suggested. When coronary spasm in controlled by treatment with nitrates or calcium antagonists, an uneventful course may be expected.

Abstract
We encountered a rare case of hypersensitivity pneumonitis associated with bilateral hilar lymphadenopathy (BHL). The patient was a 53-year-old male, who developed dry cough and shortness of breath when using a humidifier since 1982. He was admitted to our hospital for further evaluation in 1987. Chest X-ray films showed BHL and ground glass appearance in the bilateral lung fields. Pulmonary function test indicated disturbance of diffusing capacity. Transbronchial lung biopsy revealed interstitial pneumonitis, and lymph node biopsy by mediastinoscopy showed lymphoid sinus histiocytosis without noncaseating granuloma. Provocation test using the humidifier was positive, and the diagnosis of humidifier lung with BHL was made.

Abstract
The authors have measured the power and endurable grip strength by five times repetition at five second intervals on post-office clerks (indoor service and outdoor service) and the personnel of harbor construction office (office workers and crew of dredger). The results are as follows: 1) Grip strength (power: higher value either at the first or the second grip) has negative correlation with age. 2) Endurable grip strength (endurance: subtract lower value either at the fourth or fifth grip from the grip strength) of the indoor mail clerks and office workers has no correlation with age, but that of the others (the outdoor service and crew of dredger) has negative correlation with age.
