NME1 is a well-known metastasis suppressor which has been reported to be downregulated in some highly aggressive cancer cells. Although most studies have focused on NME1, the NME1 gene also encodes the protein (NME1L) containing N-terminal 25 extra amino acids by alternative splicing. According to previous studies, NME1L has potent anti-metastatic activity, in comparison with NME1, by interacting with $IKK{\beta}$ and regulating its activity. In the present study, we tried to define the role of the N-terminal 25 amino acids of NME1L in $NF-{\kappa}B$ activation signaling. Unfortunately, the sequence itself did not interact with $IKK{\beta}$, suggesting that it may be not enough to constitute the functional structure. Further construction of NME1L fragments and biochemical analysis revealed that N-terminal 84 residues constitute minimal structure for homodimerization, $IKK{\beta}$ interaction and regulation of $NF-{\kappa}B$ signaling. The inhibitory effect of the fragment on cancer cell migration and $NF-{\kappa}B$-stimulated gene expression was equivalent to that of whole NME1L. The data suggest that the N-terminal 84 residues may be a core region for the anti-metastatic activity of NME1L. Based on this result, further structural analysis of the binding between NME1L and $IKK{\beta}$ may help in understanding the anti-metastatic activity of NME1L and provide direction to NME1L and $IKK{\beta}$-related anti-cancer drug design.

This is a humanistic study to trace phenomena logically the comprehensive therapeutic mechanism of the human body which is coded by the smart emotion of the rated signal conveyed by the Rated Sijo. The Gestalt, which is structured in the form of therapeutic metastasis conveyed by sentences, is intended to embody the principle of human response. So, this researcher explored the metastatic structure toward Gestalt of original human being through the passage of foreground and background by ergonomic and chemical structure. In the meantime, this researcher focused on revealing the structure of the field of existence by the symbol system in which the therapeutic mechanism of the human body is embodied. As a result, the basic framework of Gestalt literary therapy, which contributes to the improvement of the Quality of Life metaphorized as a mechanism of the symbol system by the metastasis of literary therapy or the electrical operation of the human body. As a result, the human body as a conductor through literature has turned out to be an original Gestalt structure pursued by literature. In addition, it was analyzed that the human body would accept signals such as emotions and Rated Emotions planted in the sentence, and synapse them into the human physiological psycho analytical symbol system. Therefore, it has been confirmed possibility that human existent environment and trauma are separated from the whole universe can push fully implement therapeutic techniques toward totalization by a combination of literary devices, especially appropriate electric signal combination of the Rated Sijo.

To examine the new practical utilization of mucilages in Opuntia humifusa, polysaccharides were isolated from O. humifusa and their anti-metastatic activity and structural analysis were carried out. In experimental lung metastasis of B16BL6 melanoma cells, prophylactically intravenous (i.v.) administration of the crude polysaccharide (CNC-0) from O. humifusa significantly inhibited lung metastasis in a dose-dependant manner. The main polysaccharide, CNC-Ia was purified to homogeneity from CNC-0 by two successive column chromatographies using DEAE-Sepharose FF and Sephadex G-100 and its structure was characterized. Molecular mass of CNC-Ia was estimated to be 700 kDa and it mainly consisted of arabinose, galactose and xylose in addition to two minor sugars such as rhamnose and fucose. Methylation analysis indicated that CNC-Ia comprised at least 18 different glycosyl linkages such as terminal Araf, 5-linked Araf, 4-linked Galp and terminal Xylp in addition to three characteristic linkages such as full branched Araf, 3,4,6-branched Galp and full branched Galp. To analyze the fine structure of CNC-Ia, it was sequentially digested by exo-${\alpha}$-L-arabinofuranosidase and endo-${\beta}$-1,4-D-galactanase. These analyses suggested that CNC-Ia belongs to be a highly branched Type I arabinogalactan which has a ($1{\rightarrow}4$)-${\beta}$-galactan backbone with arabinosyl oligosaccharide side chains.

A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Bisphosphonate are a class of drugs with a chemical structure which inhibit bone resorption, actually used for metastatic bone disease, osteoporosis, Paget's disease and multiple myeloma. Significant complication associated with their use is reported recently : mandibular and maxillary osteomyelitis or osteonecrosis. So we here report our case about the patient who was diagnosed of prostate cancer in 2004 April and treated with bisphosphonate(Zoledronic acid-$Zometa^{(R)}$, Novartis Co.) intravenously every 3 to 4weeks at a dose of 4mg to prevent bone metastasis, and also, the patient who came to the hospital due to the bony exposure of mandible and pain in 2006 November and was diagnosed osteomyelitis of mandible as a result of biopsy, bone scan, PET CT examination.

Carcinomas of the stomach can spread to adjacent structure by local extension or metastasize to lymph nodes, peritoneum and distant organs. However, the incidence of metastatic bladder cancer originated at the stomach is very rare. A fifty-five year-old man admitted complaining of epigastric pain for 2 months. A large ulceroinfiltrative lesion was seen in the low body, which was confirmed poorly differentiated adenocarcinoma by histological examination. Abdominopelvic CT scan showed wall thickening at the greater curvature side of gastric body and urinary bladder. Urine cytology was negative. By transurethral resection of bladder, he was diagnosed as metastatic adenocarcinoma of the bladder. We report a case of stomach cancer with metastasis to urinry bladder.

The activity of N-acetylglucosamitnyltransferase(GnT) III and V on a Melanoma B-16 was examined after incubation with interleukin 1 (IL-1). While augumenting cell proliferation, IL-1 resulted in a decrease of GnT-III activity and an increase of GnT-V activities. Consistant with this, Melanoma B-16 cultured with IL-1 showed increased affinlity to Daturam stramonium lectin, which recognizes asialo-tri- and asialeo-tetra-antenery N-linked oligosaccharides. These results indicate that IL-1 modulate glycosyltransferase activity and the oligosaccharide structure of target cells. On the other hand, to investigate whether or not TKM-SG affect GnT-V gene expression in lung metastatic carcinoma, we used RT-PCR methods. TKM-SG treated cell lines showed low levels of secretion of GnT-V mRNA transcription as elucidated by RT-PCR. Thus, with together lower GnT-V activity levels in the medium, TKM-SG was highly effective for lung cancer metastasis treatment and it was concluded that the medicine can be used as a potent anti-lung cancer metastasis medicine.

The authors diagnosed a 54-year-old male as central mucoepidennoid carcinoma after undergoing clinical, radiological and histopathological examinations. The characteristics were as followed : 1. Clinically, the patient complained of the painless unilateral swelling of the left mandibular molar region and had a pus discharge through the fistula. Painful nodule was palpated on the scalp of the left frontal area and it was regarded as a metastatic lesion. 2. Plain radiographs showed the ill-defined permeative radiolucent lesion. The osteolytic lesions were also detected in the cranial bone, number 9 and 11 ribs, scapula, and vertebral bodies. 3. The mandibular CT and PNS MRI showed the swelling of the left mandible and the enlargement of the several lymph nodes of 1.5 cm in size. 4. Histopathologically, many solid epidermoid type cells were mixed with mucus-secreting cells and they were arranged in duct-like structure. Most of them were epidermoid type, which indicates a high grade tumor. Mucins could be found in mucicamrine staining.

Primary thymic adenocarcinoma is a very rare malignancy of the anterior mediastinum with no standardized treatment. A 36-year-old male patient presented with hoarseness over the past 3 months. A chest computed tomography (CT) scan showed an infiltrative mass to the proximal vessels and aortic arch in left upper mediastinum ($4.1{\times}3.1{\times}5.4cm$). Brain magnetic resonance imaging (MRI) showed focal lesions, suggesting metastasis in the left frontal lobe. A thoracoscopic biopsy of the mediastinal mass confirmed a primary thymic adenocarcinoma forming a glandular structure with atypia of tumor cells. The patient received four cycles of systemic chemotherapy, consisting of etoposide and cisplatin, with concurrent radiotherapy (6,000 cGy/30 fractions) to the mediastinal lesion and the metastatic brain lesion (4,200 cGy/12 fractions). A follow-up chest CT scan and brain MRI showed a decrease in the size of the left upper mediastinal mass and brain lesion. We report a rare case of the primary thymic adenocarcinoma with a literature review.
