Abstract
Undifferentiated pleomorphic sarcoma (UPS) is the second most common soft tissue sarcoma. For patients with unresectable or metastatic disease, chemotherapies are considered, but in many cases they are not curative. There is a need to identify specific molecular dysregulations that can be therapeutic targets. We focused on neurotensin receptor 1 (NTSR1), which belongs to the G-protein-coupled receptor. NTSR1 expression was upregulated in specimens from patients with UPS. Real-time polymerase chain reaction showed that expression of NTSR1 messenger RNA was 5- to 7-fold increased in UPS cells compared with myoblasts. Western blot showed a high expression of NTSR1 protein in UPS cell lines. Knockdown of NTSR1 prevented UPS cell proliferation and invasion. We confirmed that SR48692, an inhibitor of NTSR1, exhibited antitumor activities in UPS cells. The combination index showed that SR48692 and standard chemotherapeutic drugs prevented UPS cell proliferation synergistically. Mouse xenograft models showed that SR48692 inhibited extracellular signal-regulated kinase phosphorylation and enhanced the response to standard chemotherapeutic drugs. Inhibition of NTSR1 improved the effect of standard chemotherapeutic drugs for UPS. SR48692 may be a new drug for targeted UPS therapy.

The histone deacetylase inhibitor LBH589 inhibits undifferentiated pleomorphic sarcoma growth via downregulation of FOS-like antigen 1. Mol Carcinog 2018; 58:234-246.

Abstract
Undifferentiated pleomorphic sarcoma (UPS) is the second most frequent soft tissue sarcoma. Because of its resistance to chemotherapy, UPS patients are treated with surgical resection and complementary radiotherapy. However, since standard chemotherapy has not been established, unresectable or metastatic cases result in a poor prognosis. Therefore, the identification of a more effective therapy for UPS patients is needed. The development and progression of malignant tumors involve epigenetic alterations, and histone deacetylases (HDAC) have become a promising chemotherapeutic target. In this study, we investigated the potential effects and mechanisms of an HDAC inhibitor, LBH589, in UPS cells. We confirmed that LBH589 exhibits potent antitumor activities in four human UPS cell lines (GBS-1, TNMY-1, Nara-F, and Nara-H) and IC50 values ranged from 7 to 13 nM. A mouse xenograft model showed that LBH589 treatment effectively suppressed tumor growth. FACS analysis showed that LBH589 induced apoptosis and G2/M cell cycle arrest. Among apoptosis-related proteins, the expressions of Bcl-2 and Bcl-xL were decreased and the expression of Bak and Bim increased. Among cell cycle-related proteins, reductions of CDK1, p-CDK1, cyclin B1, Aurora A, and Aurora B were observed after LBH589 treatment. RNA microarray identified the FOS-like antigen 1 (FOSL1) gene as a downregulated gene in response to LBH589 in UPS cells. While knockdown of FOSL1 decreased UPS cell proliferation, overexpression induced cell proliferation. Our results show that LBH589 could be a promising chemotherapeutic agent in the treatment of UPS and downregulation of the FOSL1 gene could be the new molecular target of UPS treatment.

Characterization of the new human pleomorphic undifferentiated sarcoma TP53-null cell line mfh-val2. Cytotechnology 2017; 69:539-550. [PMID: 28676915 DOI: 10.1007/s10616-017-0112-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Accepted: 04/21/2016] [Indexed: 01/01/2023] Open
Abstract
Pleomorphic undifferentiated sarcoma (PUS), also called malignant fibrous histiocytoma, is a soft tissue sarcoma which occurs predominantly in the extremities. Its origin is a poorly defined mesenchymal cell, which derives to histiocytic and fibroblastic cells. The patient, a 58 year-old man, presented a lesion located in the forearm composed by spindle cells and multinucleated giant cells, which expressed vimentin and adopted a histological pattern formed by irregular-swirling fascicles. Cells were cultured in vitro and a new cell line was established. We characterized this new cell line by histological analyses, cytogenetics (using G-bands and spectral karyotype technique) and cytometric analyses. Cells were grown in culture for more than 100 passages. They had elongated or polygonal morphology. The cells presented a saturation rate of 70,980 cells/cm2, a plating efficiency of 21.5% and a mitotic index of 21 mitoses per field. The cell line was tumorigenic in nude mice. The ploidy study using flow cytometry revealed an aneuploid peak with a DNA index of 1.43. A side population was detected, demonstrating the presence of stem and progenitor cells. Cytogenetics showed a hypotriploid range with many clonal unbalanced rearrangements. Loss of p53 gene was evidenced by MLPA. We describe, for the first time, the characterization of a new human PUS TP53-null cell line called mfh-val2. Mfh-val2 presents a wide number of applications as a TP53-null cell line and a great interest in order to characterize genetic alterations influencing the oncogenesis or progression of PUS and to advance in the biological investigation of this tumor.

Transcutaneous application of CO2 enhances the antitumor effect of radiation therapy in human malignant fibrous histiocytoma. Int J Oncol 2014; 45:732-8.

Abstract
Sarcomas are relatively resistant because of hypoxia. We previously demonstrated that the transcutaneous CO(2) therapy reduced hypoxic conditions in human malignant fibrous histiocytoma (MFH). Therefore, we hypothesized that transcutaneous CO(2) therapy could enhance the antitumor effect of radiation therapy in human MFH. Our purpose was to evaluate the effects of transcutaneous CO(2) therapy on the antitumor efficacy of X-ray irradiation using MFH. First, in an in vitro study, we assessed apoptotic activity and reactive oxygen species (ROS) production using flow cytometric and immunoblot analysis at 24 h after X-ray irradiation under three different oxygen conditions (normoxic, reoxygenated and hypoxic). In addition, in the in vivo study, 24 male athymic BALB/c nude mice with MFH tumors that were inoculated in the dorsal subcutaneous area were randomized into four groups: control, CO(2), X-ray irradiation and combination (CO(2) and X-ray irradiation). Treatments were performed twice weekly for 2 weeks, four times in total. Tumor volume was calculated. All tumors were excised and apoptotic activity, ROS production, related proteins and HIF-1α expression were assessed using flow cytometric and immunoblot analysis. The in vitro study revealed that X-ray irradiation induced increased apoptosis and ROS production in MFH cells under normoxic and reoxygenated conditions relative to hypoxic conditions (P<0.01). In the in vivo study, tumor volume in the combination group was reduced to 28, 42 and 47% of that in the control, CO(2), and X-ray groups, respectively (P<0.05). Apoptotic activity and ROS production in the combination group were strongly increased with decreasing HIF-1α expression relative to the control, CO(2) and X-ray groups. The transcutaneous CO(2) system enhanced the antitumor action of X-ray irradiation and could be a novel therapeutic tool for overcoming radio-resistance in human malignancies.

Abstract
Fibrous dysplasia (FD) is sometimes accompanied by extraskeletal manifestations that can include any combination of café-au-lait macules, hyperfunctioning endocrinopathies, such as gonadotropin-independent precocious puberty, hyperthyroidism, growth hormone excess, FGF23-mediated renal phosphate wasting, and/or Cushing syndrome, as well as other less common features. The combination of any of these findings, with or without FD, is known as McCune-Albright syndrome (MAS). The broad spectrum of involved tissues and the unpredictable combination of findings owe to the fact that molecular defect is due to dominant activating mutations in the widely expressed signaling protein, Gsα, and the fact these mutations arises sporadically, often times early in development, prior to gastrulation, and can distribute across many or few tissues.The complexity can be mastered by a systematic screening of potentially involved tissues and cognizance that the pattern of involved tissues is established, to some degree, in utero. Thorough testing allows the clinician to establish, often times at presentation, the full extent of the disease, and importantly as well what tissues are unaffected. Treatment and follow-up can then be focused on affected systems and a meaningful prognosis can be offered to the patient and family. The authors outline screening and treatment strategies that allow for effective management of the extraskeletal manifestations of FD.

Establishment of a new human pleomorphic malignant fibrous histiocytoma cell line, FU-MFH-2: molecular cytogenetic characterization by multicolor fluorescence in situ hybridization and comparative genomic hybridization. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2010; 29:153.

Abstract
Background Pleomorphic malignant fibrous histiocytoma (MFH) is one of the most frequent malignant soft tissue tumors in adults. Despite the considerable amount of research on MFH cell lines, their characterization at a molecular cytogenetic level has not been extensively analyzed. Methods and results We established a new permanent human cell line, FU-MFH-2, from a metastatic pleomorphic MFH of a 72-year-old Japanese man, and applied multicolor fluorescence in situ hybridization (M-FISH), Urovysion™ FISH, and comparative genomic hybridization (CGH) for the characterization of chromosomal aberrations. FU-MFH-2 cells were spindle or polygonal in shape with oval nuclei, and were successfully maintained in vitro for over 80 passages. The histological features of heterotransplanted tumors in severe combined immunodeficiency mice were essentially the same as those of the original tumor. Cytogenetic and M-FISH analyses displayed a hypotriploid karyotype with numerous structural aberrations. Urovysion™ FISH revealed a homozygous deletion of the p16INK4A locus on chromosome band 9p21. CGH analysis showed a high-level amplification of 9q31-q34, gains of 1p12-p34.3, 2p21, 2q11.2-q21, 3p, 4p, 6q22-qter, 8p11.2, 8q11.2-q21.1, 9q21-qter, 11q13, 12q24, 15q21-qter, 16p13, 17, 20, and X, and losses of 1q43-qter, 4q32-qter, 5q14-q23, 7q32-qter, 8p21-pter, 8q23, 9p21-pter, 10p11.2-p13, and 10q11.2-q22. Conclusion The FU-MFH-2 cell line will be a particularly useful model for studying molecular pathogenesis of human pleomorphic MFH.

Abstract
Malignant fibrous histiocytoma (MFH) is one of the highest-grade sarcomas arising in bone and soft tissue. Its prognosis is poor because of chemoresistance and high metastatic potential to various organs. Few cases arising of MFH of the mandible or oral cavity have been documented. We established a tumor line in nude mice (MFH-N), which was derived from human MFH of the mandible and examined the characteristics of this tumor line. Histologically, MFH-N was identical to the original tumor and showed a storiform-pleomorphic pattern, but had low metastatic potential. Immunohistochemically, both the original and xenografted tumors expressed vimentin, S-100, alpha-SMA, and histiocytic marker CD68. Lysozyme was expressed by the original tumor, but only sporadically by the xenografted tumor. RT-PCR analysis demonstrated human beta-actin in this tumor line, indicating the human origin. In a parallel experiment, we established a new MFH cell line (MFH-NC) from MFH-N. Tumor cells inoculated into the flanks and submandibular region of nude mice developed into tumors histologically similar to MFH-N and the original tumor; multiple lung metastases were detected approximately 5 months after inoculation. The expression levels of various metastasis-related molecules differed between MFH-N and MFH-NC on Western blotting. In MFH-NC, the expressions of MMP7, MMP9, MT1-MMP, CXCR4, COX-2 and integrin alpha4 were up-regulated, while those of MMP2 and TIMP1 were down-regulated. Expression of TIMP2, integrinalphaL and sialyl lewis X were not detected in either line. Our findings suggest that the MFH-N tumor line transplantable in nude mice is a useful model for studying the biological behavior of MFH.
