Abstract
The current study was carried out to investigate the role of wogonin in proliferation and invasion of skin epithelioid carcinoma cells as well as its underlying mechanisms. For this purpose, skin epithelioid carcinoma cells were treated with 0, 5, 10 and 20μmol/L wogonin for 24, 48, 72 hours. Cell proliferation was evaluated by an MTT assay. Cell invasion was assessed by the Transwell invasion assay. The Notch1 level was analyzed by RT-qPCR for mRNA and by Western blot for protein. Results showed that wogonin inhibited the proliferation and invasion of skin epithelioid carcinoma cells in a dose-dependent manner. Wogonin treatment significantly decreased the mRNA and protein levels of Notch1. Moreover, the inhibition of cell proliferation and invasion ability by wogonin treatment was dramatically attenuated after co-treatment with 20 ng/mL doxycycline, a specific Notch1 activator. In conclusion, wogonin may inhibit skin epithelioid carcinoma cell proliferation and invasion at least partially by repressing the Notch1 gene expression.

Abstract
Epithelioid cells in the chicken thoracic aorta are chemoreceptor cells that release 5-HT in response to hypoxia. It is likely that these cells play a role in chemoreception similar to that of glomus cells in the carotid bodies of mammals. Recently, H2S was reported to be a key mediator of carotid glomus cell responses to hypoxia. The aim of the present study was to reveal the mechanism of action of H2S on 5-HT outflow from chemoreceptor cells in the chicken thoracic aorta. The 5-HT outflow induced by NaHS, an H2S donor, and Na2S3, a polysulfide, was measured by using a HPLC equipped with an electrochemical detector. NaHS (0.3-3mM) caused a concentration-dependent increase in 5-HT outflow, which was significantly inhibited by the removal of extracellular Ca(2+). 5-HT outflow induced by NaHS (0.3mM) was also significantly inhibited by voltage-dependent L- and N-type Ca(2+) channel blockers and a selective TRPA1 channel blocker. Cinnamaldehyde, a TRPA1 agonist, mimicked the secretory response to H2S. 5-HT outflow induced by Na2S3 (10μM) was also inhibited by the TRPA1 channel blocker. Furthermore, the expression of TRPA1 was localized to 5-HT-containing chemoreceptor cells in the aortic wall. These findings suggest that the activation of TRPA1 and voltage-dependent Ca(2+) channels is involved in H2S-evoked 5-HT release from chemoreceptor cells in the chicken aorta.

Abstract
Epithelioid inflammatory myofibroblastic sarcoma is extremely rare and belongs to a variant of inflammatory myofibrobalstic tumor with aggressive clinical course. We describe a case of a 22 years old man presented with an abdominal huge tumor. Microscopically, the neoplasm cells were rounded and epithelioid in shape. Abundant interstitial edema and less myxoid stroma were also present together with an inflammatory infiltrate. Fluorescence in situ hybridization revealed that ALK gene presented mutation. After surgery the patient received chemotherapy with an anaplastic lymphoma kinase (ALK) inhibitor, crizotinib. The patient continues to be alive with disease for 16 months and has no recurrence. Although EIMS has a poor prognosis, this is the few successful case with sustained response of targeted therapy.

Abstract
Bone epithelioid angiosarcoma (EA) is rare and characterized by large, mildly to moderately pleomorphic epithelioid cells, with abundant eosinophilic cytoplasm, vesicular nuclei, and prominent nucleoli. The tumors may arise in various locations in bone and the patients may present with unifocal or multifocal osseous disease. We present a unifocal lesion case of EA of the ilium in a 62-year-old woman. A needle biopsy of the ilium was performed and first diagnosed poorly differentiated adenocarcinoma based on CKpan and CK18 immunopositivity. The tumor was treated initially with curettage followed by chemotherapy. The final diagnosis on the surgical specimen was epithelioid angiosarcoma.

Abstract
Transforming growth factor beta (TGF-β) has been implicated in the pathogenesis of several diseases including infection with intracellular pathogens such as the Mycobacterium avium complex. Infection of macrophages with M. avium induces TGF-β production and neutralization of this cytokine has been associated with decreased intracellular bacterial growth. We have previously demonstrated that epithelioid cell surrogates (ECs) derived from primary murine peritoneal macrophages through a process of differentiation induced by IL-4 overlap several features of epithelioid cells found in granulomas. In contrast to undifferentiated macrophages, ECs produce larger amounts of TGF-β and inhibit the intracellular growth of M. avium. Here we asked whether the levels of TGF-β produced by ECs are sufficient to induce a self-sustaining autocrine TGF-β signaling controlling mycobacterial replication in infected-cells. We showed that while exogenous addition of increased concentration of TGF-β to infected-macrophages counteracted M. avium replication, pharmacological blockage of TGF-β receptor kinase activity with SB-431542 augmented bacterial load in infected-ECs. Moreover, the levels of TGF-β produced by ECs correlated with high and sustained levels of ERK1/2 activity. Inhibition of ERK1/2 activity with U0126 increased M. avium replication in infected-cells, suggesting that modulation of intracellular bacterial growth is dependent on the activation of ERK1/2. Interestingly, blockage of TGF-β receptor kinase activity with SB-431542 in infected-ECs inhibited ERK1/2 activity, enhanced intracellular M. avium burden and these effects were followed by a severe decrease in TGF-β production. In summary, our findings indicate that the amplitude of TGF-β signaling coordinates the strength and duration of ERK1/2 activity that is determinant for the control of intracellular mycobacterial growth.

Abstract
The epithelioid trophoblastic tumor is an unusual type of trophoblastic tumor. Herein, we describe a patient with coexisting epithelioid trophoblastic tumor and choriocarcinoma in the uterus. The patient had a history of hydatidiform mole with recurrent elevation of human chorionic gonadotrophin level that is resistant to chemotherapy. Histopathologic and immunohistochemical examination showed distinctive differences between the 2 trophoblastic tumors. The development of epithelioid trophoblastic tumor may be related to the persistence of locally invasive disease, which was unresponsive to chemotherapy. The patient responded well to surgery. The presence of an epithelioid trophoblastic tumor should be considered in chemoresistant gestational trophoblast tumor.

Abstract
Aflatoxin B1 (AFB1 ) is a carcinogenic mycotoxin found in feeds and in airborne grain dusts. Aflatoxin B1 requires biotransformation to the AFB1-8,9 epoxide (AFBO) by a bioactivation system and subsequent covalent binding to DNA or proteins, to exert its carcinogenic potential. The lung contains cytochrome P450, prostaglandin-H-synthase, lipoxygenase, epoxide hydrolase and other bioactivation enzymes, and is thus a potential target for the effects of AFB1 via the routes of inhalation and ingestion. The A549 human epithelioid lung cell line and the methylthiazol tetrazolium (MTT) bioassay were used to investigate the cytotoxicity of AFB1 and its chemically synthesised epoxide (AFBO) in vitro. Statistical analysis of the MTT results indicated that there were overall significant differences between the control and both the AFB1-treated (p < 0.0001) and AFBO-treated cells (p = 0.002). However, there was no significant difference between AFB1 and AFBO-treated cells, when the entire range of concentrations were assessed against each other (p = 0.2877). When analysed at each concentration, only at 0.01 mM was there a significant difference between the effects of AFB1 and AFBO (p = 0.0358). The results of this investigation show that AFB1 and AFBO are both cytotoxic in the A549 cell line.

Abstract
The incidence of epithelioid sarcoma among patients with malignant soft tissue tumors is small, but the rates of recurrence and metastasis of this type of sarcoma are high. To date, effective chemotherapy for advanced epithelioid sarcoma has not been established and, furthermore, epithelioid sarcoma is known to exhibit multidrug resistance (MDR). The chemosensitivities to anticancer agents of two cell lines established from epithelioid sarcoma were examined in this study. The results showed that the ES-OMC-MN and SFT-8606 cell lines were resistant to vincristine (IC50 1190 nM and 872 nM, respectively) and Adriamycin (IC50 921 nM and 650 nM, respectively), but sensitive to actinomycin D (IC50 < 10 nM). P-glycoprotein (p-Gp) and MDR-associated protein (MRP) were not expressed in these cell lines, but a high expression level of lung resistance protein (LRP) was observed. The original tumor tissues from which the two cell lines were established were also found to be LRP-positive but not to express p-Gp or MRP. Their chemosensitivities to Adriamycin were not significantly altered in the presence of 2.5 microg/ml anti-LRP antibody (LRP-56), but the IC50 of vincristine was much less (IC50 128 nM and 27 nM, respectively) than that for an untreated cell line. It is thus suggested that the vincristine resistance in the two cell lines is LRP-mediated. Since cyclosporin A, known to be a modifier of p-Gp, also induced reversal of vincristine resistance in the ES-OMC-MN and SFT-8606 cell lines (IC50 6.2 nM and 17 nM, respectively), it is suggested that cyclosporin A acts as a modifier of MDR mediated by LRP.

Abstract
1. Voltage-dependent and oxygen-sensitive currents in 5-HT-containing epithelioid cells isolated from chicken thoracic aorta were examined using the whole-cell patch clamp technique. 5-HT immunoreactive cells were identified with Neutral Red. The release of 5-HT from chicken thoracic aorta in the presence of excess KCl and veratridine was also examined using HPLC. 2. At a holding potential of -70 mV with CsCl pipette solution, depolarizing steps between -30 and +60 mV produced inward currents that were blocked by tetrodotoxin (0.2 microM). In the presence of tetrodotoxin and BaCl2 (5 mM), depolarizing steps evoked slow inward currents that were sensitive to CoCl2 (2 mM). Nifedipine (1 microM) decreased the currents to 79.4 +/- 1.7 %, and omega-conotoxin GVIA (1 microM) to 20.2 +/- 3.8 %. 3. When KCl pipette solution was used, depolarizing potentials positive to -40 mV caused outward currents that were inhibited by tetraethylammonium chloride. The K+ currents evoked by depolarizing steps to +20 mV were reduced to 90.3 +/- 0.8 % by hypoxia in five out of seven cells. Two cells failed to respond to hypoxia. The K+ current response was partly decreased by Neutral Red (20 microM). 4. Excess KCl (60 mM) and veratridine (30 microM) both caused the release of 5-HT from aortic strips. 5-HT outputs induced by both stimuli were partly inhibited by nifedipine (1 microM) and by omega-conotoxin GVIA (1 microM), and were abolished by these drugs in combination and by extracellular Ca2+ removal. 5. These results suggest that epithelioid cells containing 5-HT act as chemoreceptor cells in the chicken aortic body, having voltage-dependent Na+, K+, and L- and N-type Ca2+ channels, and oxygen-sensitive K+ channels.

Abstract
Epithelioid cells in the chicken thoracic aorta are shown to contain 5-hydroxytryptamine (5-HT) in immunocytochemical studies. To determine whether these cells act as chemoreceptors, as do type I cells of the carotid body, we examined the effects of hypoxia and acidosis on the release of 5-HT from the chicken thoracic aorta. Hypoxia caused the output of 5-HT in incubation medium. A reduction of pH to 6.8 failed to evoke 5-HT release. The response to hypoxia was inhibited by the removal of extracellular Ca2+ and by nifedipine and omega-conotoxin GVIA. These results suggest that epithelioid cells in the chicken thoracic aorta are chemoreceptors which sense a decrease in PO2 and then release 5-HT by Ca2+ influx through voltage-dependent L- and N-type Ca2+ channels. The epithelioid cells in the chicken aorta may be a useful model for pharmacological and physiological studies of 5-HT-containing cells.
